Recommended Products for This Recipe
After making this casserole countless times, I’ve found a few products that really make a difference in how it turns out.
These aren’t necessary, but they’ll definitely level up your results.
1. Le Creuset Enameled Cast Iron Baking Dish
This baking dish distributes heat so evenly that you get a perfectly golden, crispy topping without any burnt spots.
The enameled surface makes cleanup effortless, even when cheese gets baked onto the sides.
2. Wild Planet Wild Albacore Tuna
This tuna is sustainably caught and has a much better flavor and texture than typical canned tuna. It’s meatier and less fishy, which makes a huge difference in the final dish.
3. Kettle Brand Sea Salt Potato Chips
These thick-cut chips create the crunchiest topping you’ve ever had on a casserole. Regular chips work fine, but these kettle-cooked ones stay crispy even after baking.
4. OXO Good Grips Salad Spinner
This might seem random, but I use mine to dry the frozen peas after thawing them. Excess water can make your casserole watery, and this spinner gets rid of every last drop.
Step-by-Step Instructions: How to Make Tuna Noodle Casserole
Follow these detailed steps to create the perfect tuna noodle casserole from scratch. Even if you’ve never made this before, you’ll find these instructions easy to follow.
1. Cook the Egg Noodles
- Fill a large pot with water and add a generous pinch of salt. Bring it to a rolling boil over high heat.
- Add the egg noodles and stir them gently to prevent sticking. Cook according to package directions, usually about 8 to 10 minutes, until they’re tender but still have a slight bite.
- Drain the noodles in a colander and rinse them briefly with cool water to stop the cooking process. Set them aside while you prepare the rest of the ingredients.
- Don’t throw away all the pasta water just yet. Save about 1/4 cup in case you need to thin out the sauce later.
2. Prepare the Creamy Sauce
- In a large mixing bowl, combine the cream of mushroom soup, sour cream, and milk. Whisk them together until the mixture is completely smooth with no lumps.
- Add salt and black pepper to taste. Start with about 1/2 teaspoon of salt and 1/4 teaspoon of pepper, then adjust based on your preferences.
- The sauce should be pourable but not too thin. If it seems too thick, add a splash of the reserved pasta water or a bit more milk until it reaches the right consistency.
3. Combine the Main Ingredients
- Add the drained tuna to the sauce mixture. Use a fork to break up any large chunks, but leave some texture. You don’t want it completely shredded.
- Toss in the frozen peas directly from the freezer. They’ll thaw as the casserole bakes, and this keeps them from getting mushy.
- Stir in the shredded cheddar cheese, reserving about 1/4 cup for the topping if you want extra cheese on top.
- Add the cooked noodles to the bowl and gently fold everything together until the noodles are evenly coated with the creamy sauce. Be careful not to break the noodles too much.
4. Assemble the Casserole
- Preheat your oven to 375°F (190°C) while you assemble the casserole.
- Grease your 9×13 inch baking dish with butter or non-stick spray. Make sure to get the corners and sides to prevent sticking.
- Pour the noodle mixture into the prepared baking dish and spread it out evenly with a spatula. Press down gently to eliminate any air pockets.
- If you reserved extra cheese, sprinkle it evenly over the top of the casserole now.
5. Add the Crunchy Topping
- Crush the potato chips by placing them in a zip-top bag and gently rolling over them with a rolling pin. You want them broken into small pieces, not turned into dust.
- Melt the 2 tablespoons of butter in the microwave for about 30 seconds until it’s completely liquefied.
- Toss the crushed chips with the melted butter in a small bowl until they’re evenly coated. This helps them brown nicely in the oven.
- Spread the buttered chips evenly over the entire surface of the casserole. Don’t leave any gaps, as the chips create a protective layer that keeps the casserole moist underneath.
6. Bake Until Golden and Bubbly
- Place the casserole in your preheated oven and bake for 25 to 30 minutes. You’ll know it’s done when the edges are bubbling and the chip topping turns golden brown.
- If the chips start browning too quickly but the casserole isn’t heated through yet, loosely cover it with aluminum foil for the last 10 minutes of baking.
- Watch for the sauce bubbling up around the edges. This is a good sign that everything is hot and the flavors have melded together.
- Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the sauce to thicken slightly and makes it easier to portion out.

Tips for The Best Tuna Noodle Casserole
These tried-and-true tips will help you avoid common mistakes and create the best possible casserole every single time.
- Don’t overcook the noodles: Cook them just until al dente since they’ll continue cooking in the oven. Mushy noodles ruin the texture of the whole dish.
- Drain the tuna thoroughly: Press it with paper towels to remove excess moisture. Watery tuna makes for a watery casserole.
- Use room temperature dairy: Let your sour cream and milk sit out for 15 minutes before mixing. Cold dairy can cause the sauce to separate.
- Season generously: Canned soup and tuna are often bland on their own. Taste your sauce before adding the noodles and adjust the seasoning.
- Don’t skip the butter on the chips: This is what makes them crispy and golden instead of just dried out.
- Let it rest: Those 5 minutes after baking make a huge difference in how well the casserole holds together when you serve it.
- Make ahead friendly: Assemble the entire casserole up to 24 hours in advance, cover it tightly, and refrigerate. Add 10 extra minutes to the baking time if cooking from cold.

Serving Suggestions
This casserole is hearty enough to serve as a complete meal, but a few simple sides turn it into a proper feast.
- Simple green salad: A crisp salad with a tangy vinaigrette cuts through the richness of the casserole perfectly.
- Steamed green beans: Lightly seasoned green beans add a fresh, healthy element to your plate without much effort.
- Garlic bread: Because who doesn’t love soaking up extra creamy sauce with warm, buttery bread?
- Roasted vegetables: Try my sheet pan roasted carrots, brussels sprouts, or broccoli for added nutrition and color.
- Coleslaw: The cool, crunchy texture provides a nice contrast to the warm, creamy casserole.
- Fresh fruit: A bowl of mixed berries or sliced apples gives you something light and refreshing to finish the meal.
I learned this serving technique while perfecting my Crockpot Lasagna.
Variations of Tuna Noodle Casserole
One of the best things about this recipe is how easily you can customize it to suit your taste or use what you have in your pantry.
- Mediterranean twist: Replace the peas with sun-dried tomatoes and add kalamata olives. Use feta cheese instead of cheddar for a tangy kick.
- Spicy version: Stir in diced jalapeños and use pepper jack cheese. Add a dash of hot sauce to the cream sauce for extra heat.
- Vegetable-loaded: Add sautéed mushrooms, diced bell peppers, and chopped spinach. The more veggies, the better.
- Chicken instead of tuna: Use 2 cups of shredded rotisserie chicken for a different protein. The cooking method stays exactly the same.
- Healthier option: Swap regular noodles for whole wheat, use Greek yogurt instead of sour cream, and top with crushed whole grain crackers instead of chips.
- Creamy dill version: Add 2 tablespoons of fresh dill to the sauce and use cream of celery soup instead of mushroom. This gives it a lighter, fresher flavor.
- Italian-inspired: Use Italian seasoning in the sauce, add diced tomatoes, and top with a mixture of crushed crackers and parmesan cheese.

Storage and Reheating
This casserole stores beautifully, which makes it perfect for meal prep or enjoying leftovers throughout the week.
- Refrigerator storage: Cover the baking dish tightly with plastic wrap or transfer portions to airtight containers. It will keep for 3 to 4 days in the fridge.
- Freezer storage: Wrap individual portions in plastic wrap, then aluminum foil, or use freezer-safe containers. Label with the date and freeze for up to 3 months.
- Reheating in the oven: Cover with foil and bake at 350°F for 20 to 25 minutes until heated through. Remove the foil for the last 5 minutes to crisp up the topping.
- Microwave reheating: Place a single portion on a microwave-safe plate and heat on high for 2 to 3 minutes, stirring halfway through. The chips won’t stay as crispy, but it’s still delicious.
- Thawing frozen casserole: Transfer it to the fridge the night before you plan to eat it. Once thawed, reheat using either method above.
- Preventing dry leftovers: Add a splash of milk or chicken broth before reheating to restore creaminess. Cover while reheating to trap moisture.
This pairs beautifully with my Broccoli Cheddar Soup for a complete comfort food spread.

FAQs About Tuna Noodle Casserole
1. Can I make this casserole without canned soup?
Absolutely! Make a simple white sauce by melting 3 tablespoons of butter, whisking in 3 tablespoons of flour, then gradually adding 2 cups of milk.
Season with salt, pepper, and garlic powder, then use this instead of the canned soup.
2. What can I use instead of potato chips for the topping?
Crushed crackers, breadcrumbs, or even fried onions work wonderfully.
For a healthier option, try crushed whole grain crackers or panko breadcrumbs mixed with a bit of parmesan cheese.
Whatever you choose, make sure to toss it with melted butter for the best crispy texture.
3. Can I use fresh tuna instead of canned?
You can, but it’s not necessary and actually costs significantly more. If you do use fresh tuna, cook it first by pan-searing or baking, then flake it into chunks.
You’ll need about 10 ounces of cooked fresh tuna to replace the two cans.
4. Why is my casserole watery?
This usually happens when the tuna isn’t drained well enough or the frozen peas release too much water.
Always press the tuna dry with paper towels and consider thawing and draining the peas before adding them.
Also, make sure you’re not using too much milk in the sauce mixture.
5. Can I double this recipe for a crowd?
Yes! Just use two 9×13 inch baking dishes or one large roasting pan.
Keep the baking time the same and check that both dishes are heated through before serving. This recipe scales up beautifully for potlucks and family gatherings.
