Kitchen Equipment Needed
You do not need any fancy gear for this recipe. A good-quality baking dish and a heavy skillet are really the two most important items.
- Large pot for boiling spaghetti
- Large deep skillet or sauté pan
- 9×13 glass or ceramic baking dish
- Colander for draining pasta and meat fat
- Mixing bowls (medium and large)
- Wooden spoon or spatula
- Aluminum foil
- Box grater or electric cheese grater
- Measuring cups and spoons
- Knife and cutting board
Recommended Products for This Recipe
These are products I personally reach for whenever I make this casserole, and they genuinely make a difference in how the dish comes out.
1. Le Creuset Enameled Stoneware Baking Dish
This baking dish distributes heat so evenly that the bottom of the casserole cooks through without the cheese on top burning.
The glazed interior also means cleanup is practically effortless, even with baked-on cheese. It is the kind of kitchen investment that earns its place after the very first use.
2. Rao’s Homemade Marinara Sauce
If you are not making sauce from scratch, Rao’s is hands-down the best jarred marinara on the market.
It is made with high-quality tomatoes, has no added sugar, and tastes remarkably close to homemade.
Using a great sauce at this stage means the entire dish tastes significantly better.
3. OXO Good Grips Box Grater
Always grate your own cheese for this recipe. Pre-shredded bags are coated in starch that prevents them from melting smoothly, and freshly grated cheese creates that signature gooey, stretchy pull.
This grater is sturdy, sharp, and has a comfortable grip that makes the job go quickly.
4. Lodge Pre-Seasoned Cast Iron Skillet
A cast iron skillet is ideal for browning the meat mixture because it retains high heat and gives you a proper sear on the ground beef and sausage.
That deep brown color on the meat adds real flavor to the sauce. This one from Lodge is affordable, nearly indestructible, and only gets better with use.
Step-by-Step Instructions: How to Make Southern Baked Spaghetti
1. Preheat the Oven and Prepare Your Baking Dish
- Set your oven to 350°F (175°C) and allow it to fully preheat before the casserole goes in.
- Lightly grease your 9×13 baking dish with butter or non-stick cooking spray, making sure to coat the sides as well as the bottom.
- Set the dish aside while you prepare the other components.
2. Cook the Spaghetti
- Fill a large pot with water and bring it to a rolling boil over high heat. Add a generous pinch of salt, about 1 tablespoon, to the water.
- Add 1 lb of spaghetti and cook according to the package directions, but pull it out about 2 minutes early. The pasta should be al dente (slightly firm to the bite) since it will continue cooking in the oven.
- Before draining, scoop out 1/4 cup of the starchy pasta cooking water and set it aside in a small bowl or measuring cup.
- Drain the spaghetti in a colander and toss it with 2 tablespoons of butter while it is still hot. This prevents the strands from sticking together and adds richness.
- Set the buttered pasta aside.
3. Brown the Meat and Build the Sauce
- Place a large deep skillet over medium-high heat. Once the pan is hot, add the 1 lb of ground beef and 1 lb of Italian sausage together.
- Break the meat apart with a wooden spoon or spatula as it cooks. You want small, crumbled pieces rather than large chunks.
- Cook for 7 to 8 minutes, stirring occasionally, until the meat is fully browned with no pink remaining. Let it sit undisturbed for 30 seconds at a time to develop a golden-brown crust on some pieces.
- Carefully tilt the skillet and spoon out the excess fat, or drain the meat through a colander. Leave about 1 tablespoon of fat in the pan for flavor.
- Return the meat to the pan over medium heat. Add the diced onion and diced green bell pepper.
- Cook for 4 to 5 minutes, stirring frequently, until the onion is soft and translucent and the pepper has softened.
- Add the minced garlic and cook for 1 more minute, stirring constantly so the garlic does not burn.
- Pour in the jar of marinara sauce and the drained diced tomatoes. Stir everything together.
- Add the Italian seasoning, garlic powder, onion powder, red pepper flakes (if using), and salt and black pepper to taste.
- Stir well to combine all seasonings into the sauce. Let the mixture simmer on low heat for 8 to 10 minutes, stirring occasionally, until slightly thickened and fragrant.
- Taste the sauce and adjust seasoning as needed.
4. Make the Creamy Cheese Layer
- In a medium mixing bowl, add the 8 oz of softened cream cheese and 1 cup of sour cream.
- Stir vigorously with a spoon or rubber spatula until the mixture is completely smooth and no lumps of cream cheese remain. The reserved pasta water can help loosen this mixture. Add it one tablespoon at a time if the mixture feels too thick to spread.
- Stir in 1 cup of the shredded cheddar cheese and 1 cup of the shredded mozzarella.
- Mix until the cheeses are evenly distributed throughout the cream cheese mixture. Set aside.
5. Assemble the Casserole
- Start by spreading half of the cooked, buttered spaghetti in an even layer across the bottom of your prepared 9×13 baking dish.
- Spoon all of the cream cheese mixture over the first layer of spaghetti. Use the back of a spoon or an offset spatula to spread it as evenly as possible. Do not worry if it does not reach every edge perfectly.
- Add the remaining half of the cooked spaghetti on top of the cream cheese layer in an even layer.
- Pour the entire meat sauce over the top layer of spaghetti, spreading it evenly across the surface.
- Sprinkle the remaining 1 cup of shredded cheddar evenly over the meat sauce.
- Follow with the remaining 1 cup of shredded mozzarella on top of the cheddar.
- Finish by dusting the entire top with the 1/2 cup of grated Parmesan cheese for a salty, savory crust.
6. Bake the Casserole
- Cover the baking dish tightly with aluminum foil. Tenting the foil slightly in the middle helps prevent it from touching and sticking to the cheese.
- Place the dish on the center rack of your preheated 350°F oven.
- Bake covered for 20 minutes. This allows the casserole to heat through evenly and the cheese inside to melt.
- After 20 minutes, carefully remove the foil and return the dish to the oven.
- Bake uncovered for an additional 15 minutes, or until the cheese on top is fully melted, bubbly, and starting to turn golden brown at the edges.
- If you want extra browning on top, turn the oven to broil on low for the final 2 to 3 minutes. Watch it closely so it does not burn.
7. Rest and Serve
- Remove the casserole from the oven and let it rest on the counter for 10 minutes before serving. This resting time is important because it allows the layers to set, making it much easier to scoop clean portions.
- Use a large spoon or spatula to portion the baked spaghetti onto plates. Serve hot and enjoy immediately.

Tips for The Best Southern Baked Spaghetti
A few small tweaks at different stages of the recipe can turn a good casserole into an absolutely outstanding one. Here are the tips that make the biggest difference.
- Undercook the pasta on purpose: Pulling the spaghetti out 2 minutes before it is fully done prevents it from turning mushy during the baking stage.
- Grate your own cheese: Pre-shredded bags contain anti-caking starch that keeps the cheese from melting smoothly. Freshly grated cheddar and mozzarella melt into a much creamier, stretchier topping.
- Soften the cream cheese fully: Cold cream cheese will leave lumps in your cheese layer. Leave it out on the counter for 30 to 45 minutes before mixing.
- Season every layer: Taste the meat sauce before assembling and adjust salt and pepper. A well-seasoned sauce carries the whole casserole.
- Do not skip the resting time: Letting the casserole sit for 10 minutes after baking makes an enormous difference in how cleanly it scoops and serves.
- Use a blend of beef and sausage: The Italian sausage adds fennel notes and a slightly different fat content that makes the sauce richer than using plain ground beef alone.
- Cover then uncover: Baking covered first traps steam to cook things through, then uncovering lets the top get that gorgeous bubbly, golden finish.
Another favorite: Italian Meatballs make a wonderful addition to this dish if you want to add even more protein to the casserole.
Serving Suggestions
This casserole is substantial enough to stand alone as a complete dinner, but pairing it with a few simple sides takes the whole meal to another level.
A crisp salad is always a great partner, since the brightness cuts through the richness of the baked pasta beautifully.
- Garlic bread or cornbread: Serve warm slices of Sweet Cornbread on the side for a classic Southern pairing.
- Simple green salad: A Caesar Pasta Salad adds a bright, tangy contrast to the rich meat sauce.
- Roasted or sauteed vegetables: Sauteed Cabbage or roasted broccoli round out the meal without a lot of extra effort.
- Classic coleslaw: A bowl of Vinegar Coleslaw adds a bright, tangy crunch that balances the creamy, cheesy pasta.
- Soup starter: Begin the meal with a bowl of Tomato Soup for a deeply satisfying Italian-Southern combination.
Variations of Southern Baked Spaghetti
Once you have the base recipe down, it is incredibly easy to personalize. Here are some popular variations that work beautifully with this casserole format.
- Chicken instead of beef: Use shredded rotisserie chicken or cooked ground chicken in place of the beef and sausage. My Baked Chicken Spaghetti is a full recipe built around this idea.
- Vegetarian version: Skip the meat entirely and bulk up the sauce with mushrooms, zucchini, and extra bell peppers. Check out my Vegetarian Baked Spaghetti for a fully meat-free take.
- Ricotta cheese layer: Substitute ricotta for the cream cheese in the middle layer for a more traditional Italian-American flavor profile. My Baked Spaghetti with Ricotta Cheese walks through this version in detail.
- Million dollar style: Add a layer of Velveeta or processed cheese slices beneath the shredded cheese topping for an ultra-creamy, indulgent finish. My Million Dollar Baked Spaghetti is exactly this, and it is just as good as it sounds.
- Spicy version: Add extra red pepper flakes, a diced jalapeno to the sauce, or use hot Italian sausage instead of mild for a version with real heat.
- Cream cheese variation: Swap out the sour cream for an all-cream-cheese filling combined with cheddar. My Baked Cream Cheese Spaghetti Casserole is a richer, denser version of this concept.
Storage and Reheating
This casserole stores and reheats exceptionally well, which makes it ideal for meal prep or feeding a family across multiple days.
- Refrigerator: Cover the baking dish tightly with plastic wrap or foil and refrigerate for up to 4 days. Alternatively, transfer leftovers to an airtight container.
- Freezer: Let the casserole cool completely, then wrap individual portions or the whole dish tightly in two layers of plastic wrap followed by a layer of foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating in the oven: Cover the dish with foil and reheat at 350°F for 20 to 25 minutes, or until heated all the way through. Remove the foil for the last 5 minutes to re-crisp the cheese topping.
- Reheating individual portions: Microwave a single serving on medium power for 2 to 3 minutes, stopping to stir halfway through. Cover loosely with a damp paper towel to prevent the pasta from drying out.
- Make-ahead tip: Assemble the entire unbaked casserole, cover tightly, and refrigerate for up to 24 hours. When ready to bake, add 5 to 10 extra minutes to the covered baking time since it is going in cold.

Health Benefits of Key Ingredients
While this is absolutely a comfort food dish, several of the core ingredients do bring some genuine nutritional value to the table.
It is a satisfying, protein-rich meal that can easily be part of a balanced diet when enjoyed in appropriate portions.
- Ground beef: A rich source of complete protein, iron, zinc, and B vitamins including B12, which is essential for red blood cell production and neurological health.
- Tomato-based sauce: Tomatoes are high in lycopene, a powerful antioxidant linked to heart health and reduced inflammation. Cooking tomatoes actually increases the bioavailability of lycopene compared to eating them raw.
- Garlic: Contains allicin, a compound with well-documented antimicrobial and anti-inflammatory properties. Regular consumption is associated with improved cardiovascular health.
- Bell peppers: An excellent source of vitamin C, which supports immune function and skin health. Green bell peppers also contain vitamin K and folate.
- Mozzarella and cheddar cheese: Both provide high-quality calcium and phosphorus, which are critical for strong bones and teeth. They also contribute good amounts of protein and fat-soluble vitamins.
- Spaghetti (pasta): Provides complex carbohydrates that are a steady source of energy. Whole wheat spaghetti can be substituted for added fiber and micronutrients.

FAQs About Southern Baked Spaghetti
1. Can I make this recipe ahead of time?
Yes, you can assemble the entire casserole up to 24 hours in advance, cover it tightly, and refrigerate it until you are ready to bake.
Just add about 5 to 10 extra minutes to the covered baking time since the dish will be going into the oven cold.
2. Can I use a different type of pasta instead of spaghetti?
Absolutely. Linguine, fettuccine, or even penne all work well in this casserole.
The texture and baking time will be essentially the same, so just make sure to undercook whichever pasta you choose by about 2 minutes before assembling.
3. What is the best way to prevent the casserole from drying out?
Covering the dish tightly with foil for the first 20 minutes of baking traps moisture and keeps the pasta from drying out.
Also, making sure your meat sauce is fully wet before layering helps. If the sauce looks thick, stir in a splash of water or marinara before assembling.
4. Can I freeze unbaked Southern Baked Spaghetti?
Yes, this is one of the best pasta casseroles for freezing unbaked.
Assemble it completely in a freezer-safe baking dish, wrap it tightly in two layers of plastic wrap and then foil, and freeze for up to 3 months.
Thaw it in the refrigerator overnight before baking as directed, adding extra time since it starts cold.
5. How do I keep the cheese from burning before the inside is heated through?
Baking the casserole covered for the first 20 minutes allows the inside to heat through before the cheese is exposed to direct oven heat.
Removing the foil only for the last 15 minutes gives the cheese just enough time to melt, bubble, and turn golden without burning.

- Let the casserole rest on the counter for 10 minutes before serving. This allows the layers to set so it scoops cleanly into portions.
Nutrition
Notes
- Undercook the pasta by 2 minutes before assembling. It will finish cooking in the oven and stay perfectly tender rather than mushy.
- Always grate your own cheese. Pre-shredded bags contain anti-caking starch that prevents smooth melting. Freshly grated cheddar and mozzarella create a far creamier, stretchier topping.
- Soften cream cheese fully before mixing. Leave it out at room temperature for 30 to 45 minutes so it blends without lumps.
- Make it ahead: assemble the entire unbaked casserole, cover tightly, and refrigerate up to 24 hours. Add 5 to 10 extra minutes to the covered baking time since it starts cold.
- To freeze: cool completely, wrap tightly in two layers of plastic wrap and then foil, and freeze up to 3 months. Thaw overnight in the refrigerator before baking.
- To reheat leftovers in the oven, cover with foil and bake at 350°F for 20 to 25 minutes. Remove foil for the last 5 minutes to re-crisp the cheese topping.
- Substitute ground turkey or shredded rotisserie chicken for the beef and sausage for a lighter version. For a vegetarian option, replace the meat with mushrooms, zucchini, and extra bell peppers.
- For a spicier version, use hot Italian sausage, double the red pepper flakes, or add a diced jalapeño to the sauce.
- Swap the sour cream for ricotta cheese in the middle layer for a more Italian-American flavor profile.
- Season the sauce before assembling and taste as you go. A well-seasoned meat sauce carries the entire dish.
