Ingredients You’ll Need

Pasta

12 ounces short pasta
- I like penne, rigatoni, or rotini because they hold the creamy Cajun sauce well.
- Use regular, whole wheat, or gluten-free pasta based on your needs.

Sausage and protein

12 to 14 ounces smoked sausage or andouille, sliced into coins
- Andouille gives the most authentic Cajun flavor and more heat.
- Use turkey sausage or chicken sausage if you want a lighter option.
Optional: ½ pound peeled shrimp or cooked chicken, bite-size pieces
- Add near the end if you want extra protein.

Veggies and aromatics

1 tablespoon olive oil or neutral cooking oil
1 tablespoon butter
1 small yellow onion, finely chopped
1 red bell pepper, sliced or diced
1 green bell pepper, sliced or diced
2 to 3 cloves garlic, minced
2 green onions, sliced, plus more for garnish
Optional: 1 small jalapeño, minced, for extra heat

Creamy Cajun sauce

2 to 3 tablespoons Cajun seasoning
- Use a low-sodium blend if possible, since sausage already carries salt.
- If your Cajun seasoning tastes very salty, start with 1½ tablespoons and add more at the end.
½ teaspoon smoked paprika
¼ teaspoon dried thyme
¼ teaspoon dried oregano
1 cup low-sodium chicken broth
1 cup heavy cream
- Use half-and-half for a lighter sauce, but it will coat a bit thinner.
4 ounces cream cheese, softened and cubed
- This gives extra creaminess and helps the sauce cling to the pasta.
1 cup shredded Parmesan or Romano cheese, plus extra for serving
- I prefer freshly grated cheese because it melts smoother than bagged shreds.
½ teaspoon kosher salt, more to taste
¼ to ½ teaspoon black pepper
Pinch of sugar (optional, to balance acidity and spice)

Garnishes

Extra sliced green onions
Fresh parsley, chopped
Red pepper flakes, to taste
Extra Parmesan

Pantry shortcuts and brand notes

Use a good quality smoked sausage like Aidells, Johnsonville, or a local brand with clear Cajun or andouille labeling.
Use store-bought Cajun seasoning such as Tony Chachere’s or Slap Ya Mama, but taste for salt before adding more.
Use jarred minced garlic in a pinch, though fresh garlic gives better flavor.

Equipment list

Large pot for boiling pasta
Large deep skillet or wide Dutch oven
Tongs or a large spoon for stirring
Measuring cups and spoons
Cutting board and sharp knife
Colander for draining pasta

Tips & Tricks

Salt the pasta water generously so the noodles carry flavor before they hit the sauce.
Cook the pasta just to al dente, since it will finish in the hot sauce and soak up flavor.
Brown the sausage well so it develops crispy edges and leaves tasty browned bits in the pan.
Use room temperature cream cheese so it melts into the sauce without clumps.
Add Cajun seasoning gradually and taste as you go, since different brands vary in heat and salt.
Thin the sauce with a splash of pasta water if it looks too thick.
Stir the pasta gently in the sauce so you coat every piece without breaking it.
Add extra veggies like mushrooms, zucchini, or spinach if you want more color and nutrition.
Keep kids happy by serving red pepper flakes at the table instead of loading all the heat into the pot.
Finish with a squeeze of lemon if the sauce tastes heavy; the acidity brightens everything.

How to Make Creamy Cajun Sausage Pasta Recipe

Step 1: Boil the pasta

Bring a large pot of water to a strong boil and add a big pinch of salt. Add the pasta and cook until al dente, following package timing but checking a minute early. Reserve about 1 cup of the starchy pasta water, then drain the pasta and set it aside.

Step 2: Brown the sausage

Heat a large deep skillet or Dutch oven over medium-high heat. Add the sliced sausage in a single layer and cook until browned on one side, about 3 to 4 minutes. Flip the pieces and cook another 2 to 3 minutes, until you see caramelized edges, then transfer the sausage to a plate and keep the rendered fat in the pan.

Step 3: Sauté veggies and aromatics

Lower the heat to medium and add the olive oil and butter to the same pan. Add the onion and bell peppers, and cook until they soften and start to brown at the edges, about 5 to 7 minutes. Stir in the garlic, green onions, and jalapeño if you use it, and cook 1 to 2 minutes until fragrant.

Step 4: Build the Cajun flavor base

Sprinkle in the Cajun seasoning, smoked paprika, thyme, and oregano. Stir so the spices coat the veggies and toast slightly, about 1 minute, which deepens the flavor. If the pan looks dry, add a small splash of chicken broth to loosen the browned bits.

Step 5: Make the creamy sauce

Pour in the chicken broth and stir, scraping up all the flavorful bits from the bottom of the pan. Add the heavy cream and bring the mixture to a gentle simmer, not a hard boil, while you stir. Add the cream cheese cubes and stir until they melt and smooth out the sauce.

Step 6: Add cheese and adjust seasoning

Lower the heat and stir in the shredded Parmesan until it melts and thickens the sauce. Taste the sauce, then add salt, black pepper, and a pinch of sugar if the seasoning tastes too sharp. If the sauce looks too thick, stir in a splash of reserved pasta water until you like the consistency.

Step 7: Combine pasta and sausage

Return the browned sausage and any juices from the plate to the pan. Add the cooked pasta and toss everything together so the sauce coats each piece. If you use shrimp or cooked chicken, stir it in now and cook just until heated through and opaque in the case of shrimp.

Step 8: Finish and serve

Turn off the heat and let the pasta sit for 2 to 3 minutes so it thickens slightly and the flavors settle. Sprinkle extra green onions, parsley, red pepper flakes, and more Parmesan over the top. Serve the Creamy Cajun Sausage Pasta Recipe hot, straight from the pan, while the sauce still clings luxuriously to the noodles.

What to Serve with Creamy Cajun Sausage Pasta Recipe

This Creamy Cajun Sausage Pasta Recipe pairs nicely with a crisp green salad with a simple vinaigrette to cut through the richness. Add a side of garlic bread or warm baguette so everyone can swipe up the extra sauce. Steamed broccoli, roasted green beans, or sautéed zucchini bring color and freshness to the plate. Serve with iced tea, sparkling water with lemon, or a citrusy mocktail to cool down the Cajun spice.

Storage Options

Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
Add a splash of milk, cream, or broth before reheating to loosen the sauce.
Reheat gently on the stovetop over low to medium heat, stirring often, until hot and creamy again.
Use the microwave in short bursts, stirring between each, to avoid overcooking the pasta.
Freeze portions in freezer-safe containers for up to 2 months, then thaw overnight in the fridge before reheating with a bit of extra liquid.
