The andouille sausage brings a deep, smoky richness while the Cajun seasoning kicks up the heat just enough to keep things interesting.

What Makes This Recipe Special
- The sauce uses a clever roux-free technique-tomato paste and broth form a velvety base that clings beautifully to penne.
- Andouille sausage is seared first to render fat and build flavor, then finished in the sauce for juicy, caramelized bites.
- Cajun seasoning is divided-part cooked with the sausage, part with the veggies-to layer flavor from the start.
- A pinch of red pepper flakes adds subtle heat that builds in the background, making every bite feel alive.

Instructions
1
Fill a large pot with water and bring to a boil. Salt the water generously, add pasta, and cook until al dente according to package directions. Reserve 1 cup of pasta cooking water before draining. Drain pasta without rinsing.
2
Heat olive oil in a large skillet over medium-high heat. Add sliced andouille sausage with 2 teaspoons cajun seasoning. Cook until both sides are crisped, about 5 minutes. Transfer sausage to a clean plate.
3
Reduce heat to medium. In the same skillet, add diced onion and bell peppers, the remaining cajun seasoning, and red pepper flakes. Sauté until vegetables are softened, about 3 minutes. Stir in minced garlic and cook until fragrant, about 1 minute.
4
Whisk chicken broth, heavy cream, and tomato paste into the skillet until smooth. Bring to a gentle boil over medium-high heat, then lower to medium-low and simmer for 5 to 7 minutes to reduce and thicken slightly.
5
Add grated parmesan cheese to the sauce and stir to incorporate. Return cooked pasta and sausage to the skillet, tossing to coat evenly in sauce. If desired, thin the sauce with reserved pasta water. Serve immediately, garnishing with extra parmesan cheese and fresh chopped parsley.
Essential Tips
Slice sausage thin
Cut the andouille at a 45-degree angle into 1/4-inch slices. This increases surface area for maximum browning and crispy edges that add texture to the final dish.
Toast the Cajun seasoning
When adding Cajun seasoning to the sausage and veggies, let it sizzle for 30 seconds before adding other ingredients. This blooms the spices, unlocking deeper, more aromatic flavors in every bite.
Reserve pasta water
Save 1/2 cup of starchy pasta water before draining. Toss it into the sauce to loosen it if needed-it binds the sauce to the pasta without diluting flavor.
Add cheese off-heat
Let the sauce cool slightly after simmering, then stir in Parmesan. This prevents clumping and ensures a smooth, glossy finish.
Garnish just before serving
Fresh parsley should be added last. It brightens the dish and adds a pop of color, making the plate look as vibrant as it tastes.
Smart Swaps & Variations
Vegetarian
Swap andouille for plant-based sausage like Beyond or Field Roast. Use vegetable broth and coconut milk for a fully dairy-free version.
Lighter
Replace heavy cream with half-and-half or light coconut milk. Add a splash of olive oil to maintain richness.
Spicier
Add an extra teaspoon of Cajun seasoning or a diced jalapeño when sautéing the onions and peppers.
Creamy Tomato
Mix in 1 cup of crushed tomatoes with the broth and cream for a richer, tomato-forward sauce.
What to Serve With This
- Garlic bread or crusty baguette to soak up every bit of creamy sauce.
- A crisp arugula salad with lemon vinaigrette to cut through the richness.
- Grilled shrimp or chicken thighs for a heartier protein boost.
- Iced sweet tea or cold beer-especially a lager or IPA-to balance the heat.
Storage & Reheating
Storage
Store leftovers in an airtight container in the fridge for up to 3 days. The sauce will thicken as it cools, so you may need to add a splash of water or broth when reheating.
Reheating
Reheat gently in a skillet over low heat, stirring frequently and adding 1-2 tablespoons of broth or water to restore creaminess. Avoid microwaving, which can make the sauce grainy.
Expert Chef Tips
- Use a cast-iron skillet if you have one-it holds heat beautifully and helps the sausage caramelize evenly.
- Deglaze the skillet with a splash of beer or white wine after searing the sausage to lift up all the browned bits and deepen the sauce's flavor.
- For extra umami, stir in 1 teaspoon of fish sauce or Worcestershire sauce with the tomato paste-it won't taste fishy but adds incredible savory depth.
Equipment You’ll Need
- Large pot for boiling pasta
- Large cast-iron or stainless-steel skillet (12-inch preferred)
- Sharp chef's knife and cutting board
- Whisk for blending the sauce

Frequently Asked Questions
Can I use chicken sausage instead of andouille?
Absolutely! Choose a spicy chicken sausage to maintain the Cajun kick. If your sausage isn't pre-seasoned, add an extra teaspoon of Cajun seasoning when browning it.
What's the best way to make this gluten-free?
Use gluten-free pasta and ensure your broth and seasonings are certified GF. Check Cajun seasoning for additives, and opt for a GF sausage if needed.
Can I make this ahead of time?
Yes! Cook the pasta al dente, but undercook it by 1 minute. Reheat the sauce and sausage, then toss in the pasta and cook for 1-2 minutes to finish. The sauce will thicken as it sits, so add water as needed.
Why is my sauce grainy?
This usually happens if the Parmesan isn't fully incorporated or if the sauce boils too vigorously. Always stir in the cheese off the heat and keep the sauce at a gentle simmer.
Can I omit the heavy cream?
Yes, but the sauce will be less rich. Substitute with full-fat coconut milk or a mix of half-and-half and cream cheese for body. The flavor will shift slightly, so taste and adjust seasoning.
How do I adjust the spice level?
For milder heat, reduce the Cajun seasoning to 1 teaspoon total and skip the red pepper flakes. For more heat, add cayenne pepper or hot sauce to taste during serving.
Can I freeze this dish?
It freezes but the cream may separate upon thawing. For best results, freeze the sauce and sausage separately from the pasta. Thaw in the fridge and reheat gently, stirring in extra broth to restore texture.
What kind of pasta works best?
Short, sturdy shapes like penne, rigatoni, or fusilli hold sauce well. Avoid delicate pastas like angel hair, which can turn mushy in the creamy sauce.
