This Dirty Spaghetti Recipe takes everything you love about Louisiana dirty rice and tosses it with a big pile of spaghetti.
Ground beef, smoky andouille sausage, and the Cajun holy trinity simmer in a rich, savory gravy that coats every single strand.
There is no red sauce here, just deep brown, peppery comfort that tastes like it cooked all afternoon.
It actually comes together in about 40 minutes, which makes it a true weeknight hero.
If you love bold, saucy pasta dinners, this one will earn a spot right next to my Rasta Pasta in your regular rotation.
The “dirty” in the name comes from the dark, rustic color of the sauce, and I promise it tastes far better than it looks.

Ingredients
Everything below is easy to find, and the two ingredients worth hunting for are a good smoked sausage and a flavorful Cajun blend.
- 1 pound spaghetti
- 1 tablespoon kosher salt, for the pasta water
- 1 tablespoon olive oil
- 1 pound ground beef (80/20)
- 12 ounces andouille sausage, sliced into half-moons
- 1 medium yellow onion, diced (about 1 cup)
- 1 green bell pepper, diced
- 2 celery stalks, diced
- 4 garlic cloves, minced
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 tablespoons tomato paste
- 3 cups low-sodium beef broth
- 1 tablespoon Worcestershire sauce
- 1 tablespoon Cajun seasoning
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1/2 teaspoon black pepper
- 1 cup reserved pasta water
- 1 to 2 teaspoons Louisiana hot sauce, optional
- 3 green onions, thinly sliced, for garnish
- 2 tablespoons fresh parsley, chopped, for garnish
- Kosher salt, to taste
Choose a sausage with plenty of smoke, since it seasons the whole pot as it browns.
The same trick of letting the sausage flavor the dish is one I rely on in my Italian sausage tortellini.
Kitchen Equipment Needed
You only need a few basic tools, and most of them are probably already in your kitchen.

Recommended Products for This Recipe
These are my personal recommendations based on years of cooking big, hearty pasta dinners like this one.
None of them are required, but each one makes the recipe a little easier or a lot more flavorful.
1. Lodge Enameled Cast Iron Dutch Oven
This pot holds heat beautifully, so the beef and sausage brown deeply without scorching the bottom.
The wide, deep shape also gives you plenty of room to toss the spaghetti in the gravy without losing a single noodle over the side.
2. Aidells Cajun Style Andouille Smoked Sausage
Good andouille is the backbone of this dish, and this one has the right snap and smoky, peppery bite.
It renders just enough flavorful fat to build the gravy on. It pairs well with a big pot of shrimp and grits too.
3. Tony Chachere’s Original Creole Seasoning
This is the classic Louisiana kitchen staple, and it delivers salt, garlic, and a gentle cayenne kick in one shaker.
I use it when I want a more traditional Cajun taste. A little goes a long way, so taste before you add extra salt.
4. Cuisinart Pasta Pot with Strainer Lid
Draining spaghetti while trying to save a cup of pasta water is where most people make a mess.
This pot has a built-in strainer lid, so you can scoop out your reserved water first and drain the noodles right in the sink without a colander.
5. Victorinox Fibrox Pro Chef’s Knife
This recipe has a lot of chopping, and a sharp knife makes the onion, pepper, and celery go quickly and evenly.
Even pieces cook at the same speed, which gives the gravy a better texture. It is the best value knife I have ever owned.
Step-by-Step Instructions: How to Make Dirty Spaghetti
1. Prep All the Ingredients
- Dice the yellow onion, green bell pepper, and celery into small, even pieces about 1/4 inch wide, so they melt into the gravy.
- Mince the garlic cloves and set them aside in a small pile.
- Slice the andouille sausage into thin half-moons, about 1/4 inch thick.
- Combine the Cajun seasoning, smoked paprika, dried thyme, and black pepper in a small bowl so you can add them all at once.
- Measure the flour, tomato paste, Worcestershire sauce, and beef broth and keep them within reach of the stove.
2. Boil the Spaghetti
- Fill a large stockpot with about 4 quarts of water and bring it to a rolling boil over high heat.
- Stir in 1 tablespoon of kosher salt, then add the spaghetti.
- Cook the pasta for 1 to 2 minutes less than the package directions, usually about 8 minutes, because it will finish cooking in the gravy.
- Scoop out 1 cup of the starchy pasta water with a liquid measuring cup and set it aside.
- Drain the spaghetti in a colander and let it sit while you build the gravy. Do not rinse it.
3. Brown the Andouille Sausage
- Set a Dutch oven or large deep skillet over medium-high heat and add the olive oil.
- Once the oil shimmers, add the sliced andouille sausage in a single layer.
- Cook for 3 to 4 minutes, stirring once or twice, until the edges are browned and the sausage has released some flavorful fat.
- Transfer the sausage to a plate and leave the drippings in the pot.
4. Cook the Ground Beef
- Add the ground beef to the same pot and break it into small crumbles with a wooden spoon.
- Cook for 6 to 8 minutes, stirring often, until no pink remains and the meat is nicely browned.
- Tilt the pot and spoon out extra grease, leaving about 2 tablespoons behind for flavor.

5. Sauté the Holy Trinity and Garlic
- Add the diced onion, green bell pepper, and celery to the beef.
- Cook for about 5 minutes, stirring often, until the vegetables soften and the onion turns translucent.
- Stir in the minced garlic and cook for 30 seconds, just until fragrant.
- Sprinkle in the Cajun seasoning mixture and stir for 1 minute so the spices toast in the pot.
6. Build the Roux and Gravy
- Push the meat and vegetables to the sides of the pot and add the butter to the center.
- Once the butter melts, sprinkle the flour over the top and stir everything together for about 2 minutes to cook out the raw flour taste.
- Add the tomato paste and stir constantly for 1 minute, until it darkens slightly.
- Slowly pour in the beef broth while stirring, scraping up all the browned bits from the bottom of the pot.
- Stir in the Worcestershire sauce and return the browned sausage to the pot.
- Bring to a gentle boil, then lower the heat and simmer for 8 to 10 minutes, until the gravy thickens and coats the back of a spoon.
7. Toss the Spaghetti in the Gravy
- Add the drained spaghetti to the pot and use tongs to toss until every strand is coated.
- Pour in about 1/2 cup of the reserved pasta water and keep tossing for 2 minutes so the noodles soak up the flavor.
- Add more pasta water, a splash at a time, if the gravy looks too thick.
- Taste and add kosher salt as needed. Stir in the Louisiana hot sauce if you want extra heat.
8. Garnish and Serve
- Remove the pot from the heat and let it rest for 2 minutes so the gravy settles.
- Scatter the sliced green onions and chopped parsley over the top.
- Serve hot in wide bowls with extra hot sauce on the side.
Tips for The Best Dirty Spaghetti
A few small habits take this pasta from good to the kind of dinner people talk about later.
The roux technique is the same one I use for my creamy sausage gravy, so if you have made that, you are already ahead.
- Undercook the pasta slightly: The spaghetti finishes in the gravy, so pulling it early keeps it from turning soft.
- Save the pasta water: The starch helps the gravy cling to the noodles and gives it a silky finish.
- Brown the meat well: Deep browning builds the dark, savory base that gives the dish its name.
- Do not skip the roux: Cooking the flour for a full 2 minutes prevents a pasty taste.
- Add the broth slowly: Pouring gradually while stirring keeps the gravy smooth and lump free.
- Use low-sodium broth: Cajun seasoning and andouille are already salty, so this gives you control.
- Taste before salting: Season at the end, after the flavors have come together.
- Let it rest: Two minutes off the heat lets the gravy thicken to the perfect coating consistency.
- Choose a wide pot: More surface area means easier tossing and better browning.
Serving Suggestions
Dirty spaghetti is hearty enough to stand alone, but a simple side turns it into a full spread.
Pick something crisp, buttery, or fresh to balance the rich gravy.
- Warm, crusty garlic bread for scooping up every last bit of sauce
- A crisp green salad with a tangy vinaigrette
- Sautéed collard greens or green beans for a Southern touch
- Skillet cornbread with a drizzle of honey
- A cool, crunchy coleslaw to balance the heat
- Roasted broccoli with lemon
- Extra hot sauce and lemon wedges on the table
- A cold glass of iced tea or lemonade

Variations of Dirty Spaghetti
Once you have the classic version down, this dish is easy to bend to your pantry and your crowd.
Here are my favorite ways to switch it up.
- Ground turkey or chicken: Swap the beef for a lighter option and add an extra tablespoon of butter.
- Ground pork blend: Use half beef and half pork for a richer, juicier gravy.
- Spicy version: Add 1 diced jalapeño with the trinity and a pinch of cayenne pepper.
- Extra cheesy: Stir in 1/2 cup of freshly grated Parmesan at the end.
- Shrimp add-in: Sauté 1 pound of peeled shrimp in Cajun seasoning and fold them in just before serving.
- Gluten-free: Use gluten-free spaghetti and swap the flour for a gluten-free blend.
- Sausage swap: Use smoked sausage or ground Italian sausage if you cannot find andouille.
- Oven-baked style: Spread the finished pasta in a baking dish, top with cheese, and bake until bubbly.
If you love the baked idea, try my Southern baked spaghetti for another cozy pasta night.
Storage and Reheating
Dirty spaghetti keeps well, and the flavor often improves overnight.
Cool it quickly and store it properly for the best texture.
- Refrigerator: Store leftovers in airtight glass containers for up to 4 days.
- Freezer: Freeze in freezer-safe containers for up to 2 months, leaving a little room at the top.
- Thawing: Move frozen portions to the refrigerator overnight before reheating.
- Stovetop reheating: Warm in a skillet over medium-low heat with a splash of broth or water until hot.
- Microwave reheating: Heat in 1 minute bursts, stirring in between, and add a spoonful of water to loosen the gravy.
- Cooling tip: Do not leave the pasta out for more than 2 hours before refrigerating.
- Garnish fresh: Add fresh green onions and parsley after reheating.

FAQs About Dirty Spaghetti
1. What is dirty spaghetti?
Dirty spaghetti is a Southern-inspired pasta made with a savory beef gravy instead of red sauce.
It borrows the seasoned meat and holy trinity flavors of Cajun dirty rice and serves them over spaghetti.
2. Why is it called dirty spaghetti?
The name comes from dirty rice, which gets its color from browned meat and dark seasonings.
The gravy turns the pasta a deep, rustic brown, so it looks a little dirty even though it tastes fantastic.
3. Can I make dirty spaghetti in one pot?
Yes, you can. Break the dry spaghetti in half, add it to the simmering gravy with 2 extra cups of broth, and cook until tender, stirring often.
I prefer boiling the pasta separately for the best texture, but the one pot method is great for cleanup.
4. Is dirty spaghetti spicy?
It has a warm, gentle heat rather than a burning one.
Use a mild Cajun seasoning and skip the hot sauce for less spice, or add cayenne and a diced jalapeño for more.
5. What can I use instead of andouille sausage?
Smoked sausage, kielbasa, or ground Italian sausage all work well.
If you like Italian sausage in your pasta, my baked chicken spaghetti is another cozy way to enjoy it.
