Make it when you want a hearty meal without elaborate prepping or when you need a crowd-pleasing pasta for potlucks.
The cooking process explained
Quick overview so you know what to expect:
- Brown the sliced sausage with onion and bell pepper to build flavor.
- Add garlic, then deglaze with diced tomatoes and broth, finish with cream for richness.
- Stir in penne and simmer in the sauce until the pasta absorbs liquid and becomes tender.
- Remove from heat and fold in Parmesan to thicken the sauce into a creamy coating.
- The whole method relies on layering flavors and letting the pasta cook right in the sauce for maximum taste.
What you’ll need
- 1 lb smoked sausage, sliced (about 1/4-inch rounds)
- 12 oz penne pasta
- 2 cups chicken broth (use low-sodium if you want to control salt)
- 1 cup heavy cream
- 1 medium onion, diced
- 1 bell pepper, diced (any color)
- 3 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes
- 1 tbsp Cajun seasoning (adjust to taste)
- 1 tsp paprika
- Salt and pepper to taste
- 1 cup grated Parmesan cheese for garnish and finishing
- 2 tbsp olive oil
Substitutions and notes: opt for reduced-fat cream for a lighter finish, or use half-and-half and simmer a little longer to thicken. Swap smoked sausage for chicken or turkey sausage, or use a plant-based sausage for a vegetarian twist.
Step-by-step instructions
- Heat 2 tablespoons of olive oil in a large pot over medium heat.
- Add the sliced sausage, diced onion, and diced bell pepper. Cook, stirring occasionally, until the sausage browns and the vegetables soften, about 5 to 7 minutes.
- Stir in the minced garlic and sauté 1 minute until fragrant.
- Pour in the diced tomatoes, 2 cups chicken broth, and 1 cup heavy cream. Season with 1 tablespoon Cajun seasoning, 1 teaspoon paprika, and salt and pepper to taste. Increase heat and bring the mixture to a gentle boil.
- Add the 12 ounces penne pasta to the pot. Reduce heat to low and simmer, stirring occasionally, until the pasta is tender and the sauce has thickened, about 10 to 12 minutes. If the pasta soaks up too much liquid before it’s done, add a splash of broth or water.
- Remove the pot from the heat. Stir in the grated Parmesan until the sauce turns creamy and glossy. Taste and adjust seasoning.
- Serve immediately in bowls, topped with extra Parmesan and chopped parsley if you like.
Serving suggestions
Present this pasta in shallow bowls so the sauce shows. For texture contrast, sprinkle toasted breadcrumbs or chopped green onions on top. Offer a simple green salad dressed with a lemon vinaigrette to cut the richness. If you prefer a hands-off version for busy days, try a slow-cooker alternative such as the Crock-Pot creamy Cajun chicken pasta to plan ahead.
Storage and reheating tips
Cool leftovers quickly and store in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stovetop over low heat, adding a splash of broth or cream to loosen the sauce, and heat until it reaches 165°F (74°C). You can freeze cooled portions for up to 3 months; thaw overnight in the fridge before reheating. Always discard leftovers left at room temperature longer than two hours.
Helpful cooking tips
- Slice the sausage uniformly so pieces cook evenly.
- Use a large pot so the pasta has room to simmer without sticking.
- Stir occasionally while the pasta cooks to prevent clumping and to keep it from sticking to the bottom.
- If you want a silkier sauce, grate fresh Parmesan rather than pre-shredded—the melted texture is smoother.
- Taste before adding salt; smoked sausage and Parmesan already contribute saltiness.
- To tame the heat, reduce the Cajun seasoning by half and add black pepper or smoked paprika for flavor without extra spice.
Creative twists
- Veg-forward: add sliced mushrooms, spinach, or zucchini in step 2 to boost vegetables.
- Dairy-free: swap heavy cream for full-fat coconut milk and use a dairy-free Parmesan alternative.
- Lighter: use half-and-half or Greek yogurt (stirred in off heat) instead of heavy cream.
- Protein swap: substitute turkey or chicken sausage, or use plant-based sausage for a vegetarian version.
- Extra smoky: add a pinch of smoked paprika or a splash of hot sauce for more depth.
Common questions
How long does this recipe take from start to finish?
Active time is about 25 to 30 minutes. Browning the sausage and veggies takes roughly 7 minutes, then pasta simmers for 10 to 12 minutes.
Can I make this mild instead of spicy?
Yes. Reduce the Cajun seasoning by half and use mild paprika. Taste as you go and add more seasoning if needed.
Can I use a different pasta shape?
Absolutely. Short pasta like fusilli, rigatoni, or rotini work well because they hold the creamy sauce.
Is this safe to refrigerate and reheat?
Yes. Refrigerate within two hours of cooking and consume within 3 days. Reheat until the center reaches 165°F (74°C). Freeze in portion-sized containers for up to 3 months.
What if the sauce is too thin or too thick?
Too thin: simmer a few extra minutes uncovered to reduce it, or stir in a small handful of grated Parmesan. Too thick: add a splash of broth or cream while reheating to loosen it.
Can I prep any part of this recipe ahead?
Chop the vegetables and slice the sausage a day ahead. Store them in airtight containers in the fridge for quicker assembly.
