Why You'll Love This Recipe
About the Ingredients
12 oz (340g) andouille sausage, sliced into 1/4-inch rounds
Smoked andouille adds authentic Cajun flavor. If you can't find it, use any smoked sausage like kielbasa or chorizo.
8 oz (225g) penne pasta
Penne holds the creamy sauce well. Substitute with rotini, fusilli, or any short pasta.
2 tablespoons olive oil
Use extra-virgin for best flavor. Can substitute with canola or vegetable oil.
1 small yellow onion, finely chopped
About 1 cup. Use sweet onion if you prefer a milder bite.
3 cloves garlic, minced
Fresh garlic is best, but 1 teaspoon of jarred minced garlic works in a pinch.
1 red bell pepper, thinly sliced
Adds color and sweetness. Use any color bell pepper or substitute with 1 cup of frozen peppers.
1 cup (240ml) heavy cream
Heavy cream gives the sauce richness. For a lighter option, use half-and-half or evaporated milk.
1/2 cup (50g) grated Parmesan cheese
Freshly grated melts better. Pre-shredded may not melt as smoothly.
1 tablespoon Cajun seasoning
Adjust to taste. Use store-bought or make your own with paprika, garlic powder, and cayenne.
1/2 teaspoon salt
Adjust based on the saltiness of your sausage and seasoning.
1/4 teaspoon black pepper
Freshly ground is best.
2 tablespoons chopped fresh parsley, for garnish
Optional but adds freshness. Substitute with chives or green onions.
Tips & Tricks
Don't overcook the pasta
Cook it al dente because it will continue to cook slightly in the sauce. Reserve a cup of pasta water to thin the sauce if needed.
Use a large skillet
Ensure you have enough room to toss everything together. A 12-inch skillet is ideal to prevent crowding and ensure even cooking.
Taste as you go
Cajun seasoning can vary in saltiness and heat. Add it gradually and adjust to your preference.
Pro Tips
Step-by-Step Instructions
1. Cook the pasta
Bring a large pot of salted water to a boil (212°F / 100°C). Add penne and cook according to package instructions until al dente, about 11 minutes. Drain, reserving 1 cup of pasta water, and set aside.
2. Brown the sausage
In a large skillet, heat olive oil over medium-high heat (350°F / 175°C). Add sausage slices in a single layer and cook until golden brown on both sides, about 4-5 minutes. Use tongs to flip. Remove with a slotted spoon and set aside.
3. Sauté the aromatics
In the same skillet, reduce heat to medium (300°F / 150°C). Add onion and bell pepper, sauté until softened, about 3-4 minutes. Add garlic and cook for 30 seconds until fragrant.
4. Make the sauce
Pour in heavy cream and stir in Cajun seasoning, salt, and pepper. Bring to a gentle simmer (around 200°F / 93°C) and let cook for 2-3 minutes until slightly thickened.
5. Combine pasta and sausage
Add the cooked sausage and penne to the skillet. Stir to coat in the sauce. If the sauce is too thick, add a splash of reserved pasta water until desired consistency.
6. Add the cheese
Remove skillet from heat and stir in Parmesan cheese until melted and creamy. The residual heat is enough to melt it without curdling.
7. Garnish and serve
Sprinkle with fresh parsley and serve immediately. Enjoy hot with extra Parmesan on the side.
Delicious Variations
Chicken Cajun Pasta
Swap sausage for 2 diced chicken breasts, season with Cajun seasoning, and cook until golden and cooked through (165°F / 74°C internal temp).
Vegetarian Cajun Pasta
Omit sausage and add 1 cup of sliced mushrooms and 1 can of drained chickpeas for protein.
Spicy Shrimp Cajun Pasta
Replace sausage with 1 pound of peeled shrimp, sauté until pink and opaque (about 2 minutes per side), and add at the end.
How to Store Cajun Sausage Pasta
Refrigerator
Store in an airtight container for up to 4 days.
Freezer
Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat in a skillet over medium-low heat, adding a splash of milk or broth to loosen the sauce, or microwave in 30-second bursts.
Frequently Asked Questions
Q: Can I use regular Italian sausage instead of andouille?
Yes, you can use any smoked or cooked sausage. If using raw Italian sausage, cook it thoroughly before adding the other ingredients.
Q: How can I make this less spicy?
To reduce heat, use a mild Cajun seasoning or reduce the amount to 1/2 tablespoon. You can also add a tablespoon of brown sugar to balance the spice.
Q: Can I use milk instead of heavy cream?
Yes, but the sauce will be thinner. Use whole milk and thicken with a slurry of 1 tablespoon cornstarch mixed with 2 tablespoons cold water, added at the end.
Q: What can I substitute for Parmesan cheese?
Pecorino Romano or Asiago are great substitutes, or use a dairy-free nutritional yeast for a vegan option.
Q: How do I prevent the sauce from curdling?
Curdling can happen if the heat is too high or if you add cold cream to hot pan. Use medium-low heat and let cream come to room temperature before adding.
