If you love creamy pasta with a little heat, this Creamy Sweet Chili Cajun Sausage and Cheddar Penne is a weeknight dinner worth adding to your rotation. It combines browned sausage, tender penne, bold Cajun seasoning, sweet chili sauce, garlic, cream, and melted cheddar into one rich and satisfying skillet meal.
The flavor comes from the contrast between spicy, smoky, savory, creamy, and sweet. Cajun seasoning gives the dish its signature kick, while sweet chili sauce adds a glossy sweetness and mild chili flavor. Cream and cheddar mellow the spice and turn the sauce into a rich coating that clings to every piece of pasta.
Sausage makes this pasta especially hearty. As it browns in the skillet, the edges become caramelized and flavorful, creating a savory foundation for the sauce. You can use mild Italian sausage for a more family-friendly version or spicy sausage if you want to turn up the heat.
Penne is an ideal choice because its tubular shape catches the creamy sauce. However, there is plenty of flexibility here. Rotini, rigatoni, shells, cavatappi, or bow-tie pasta can all work.
The best part is how easy this recipe is to customize. Add spinach for freshness, bell peppers for sweetness, broccoli for extra vegetables, or Pepper Jack for even more heat. A sprinkle of green onions or parsley at the end adds freshness and color.
Serve this pasta with a simple green salad and warm garlic bread for an easy dinner that feels indulgent without requiring complicated cooking techniques.

Ingredient Notes
Sausage
Italian sausage gives the pasta a savory, herby foundation. Mild sausage allows the sweet chili sauce to stand out, while hot sausage adds another layer of spice.
Bulk sausage is convenient, but sausage links can also be removed from their casings and crumbled.
Sweet Chili Sauce
Sweet chili sauce contributes sweetness, gentle heat, and acidity. Since different brands vary in sweetness, taste the sauce before deciding whether additional sweetener is necessary.
Cajun Seasoning
Cajun seasoning provides the smoky, peppery backbone of the dish. Some blends are saltier than others, so add additional salt cautiously.
Cheddar
Sharp cheddar gives the sauce a stronger cheese flavor. Freshly shredded cheddar generally melts more smoothly than pre-shredded cheese.
Heavy Cream
Heavy cream creates the richest sauce and helps balance the Cajun seasoning and sweet chili sauce.
Penne
Penne works particularly well because its hollow centers and ridges hold onto the sauce. Other short pasta shapes are easy substitutes.
Ingredient Substitutions
- Italian sausage: Use chicken sausage, turkey sausage, smoked sausage, or plant-based sausage.
- Penne: Substitute rotini, rigatoni, shells, cavatappi, or fusilli.
- Heavy cream: Use half-and-half for a lighter sauce.
- Cheddar: Try Colby Jack, Monterey Jack, Pepper Jack, or smoked Gouda.
- Chicken broth: Vegetable broth works well.
- Sweet chili sauce: Use a mild chili sauce combined with a little honey or maple syrup.
- Cajun seasoning: Use Creole seasoning or a homemade blend of paprika, garlic powder, onion powder, oregano, thyme, and cayenne.
- Fresh garlic: Garlic paste can be used if needed.
Step-by-Step Instructions
Step 1: Cook the Penne
Bring a large pot of salted water to a boil.
Add the penne and cook according to the package directions until al dente.
Before draining, reserve approximately ½ cup of pasta water.
Drain the pasta and set aside.
Step 2: Brown the Sausage
Heat olive oil in a large skillet over medium-high heat.
Add the sausage and break it into small pieces.
Cook for approximately 5–7 minutes, stirring occasionally, until the sausage is browned and cooked through.
Don’t rush this step. The browned edges provide important flavor.
Step 3: Add the Vegetables
If using bell pepper or corn, add them to the skillet.
Cook for approximately 2–3 minutes until slightly softened.
If you’re using spinach, save it for later.
Step 4: Add Garlic and Butter
Reduce the heat to medium.
Add butter and minced garlic.
Cook for approximately 30–60 seconds, stirring frequently, until fragrant.
Avoid browning the garlic too much.
Step 5: Add Cajun Seasoning
Sprinkle in the Cajun seasoning, smoked paprika, and black pepper.
Stir until the sausage is evenly coated.
Let the spices cook briefly in the butter and sausage juices to bring out their flavor.
Step 6: Add Sweet Chili Sauce
Pour in the sweet chili sauce.
Stir thoroughly so the sausage and vegetables become coated.
Cook for approximately 1 minute.
Step 7: Add the Cream
Reduce the heat to medium-low.
Pour in the heavy cream and chicken broth.
Stir gently until the sauce is evenly combined.
Allow it to warm without bringing it to a vigorous boil.
Step 8: Melt in the Cheddar
Lower the heat.
Add shredded cheddar gradually, stirring as it melts.
Continue stirring until the sauce becomes smooth and creamy.
Step 9: Add the Pasta
Add the cooked penne to the skillet.
Toss gently until the pasta is completely coated.
If the sauce is too thick, add reserved pasta water a little at a time.
Step 10: Add Spinach
If using spinach, add it now.
Stir for 1–2 minutes until the leaves wilt into the creamy sauce.
Step 11: Taste and Adjust
Taste the pasta before adding salt.
Add extra Cajun seasoning for more spice, sweet chili sauce for additional sweetness, or crushed red pepper flakes for more heat.
If the sauce is too thick, loosen it with another splash of pasta water.
Step 12: Garnish and Serve
Turn off the heat.
Top with parsley, green onions, extra cheddar, or a small drizzle of sweet chili sauce.
Serve while hot and creamy.
Expert Tips
Brown the Sausage Well
Don’t simply cook the sausage until done. Allow it to develop browned edges for maximum flavor.
Watch the Cajun Seasoning
Cajun blends vary in saltiness and spice. Taste before adding extra salt.
Don’t Boil the Cream Sauce
A gentle simmer is enough. Aggressive boiling can cause the dairy to separate.
Use Freshly Shredded Cheese
Block cheese generally melts more smoothly into creamy sauces.
Save Pasta Water
Starchy pasta water is perfect for thinning a thick sauce while maintaining its creamy consistency.
Cook Pasta Al Dente
The pasta will continue absorbing sauce after it enters the skillet, so avoid overcooking it.
Add Cheese Over Low Heat
Low heat helps the cheddar melt smoothly without becoming greasy.
Balance Sweetness and Heat
Taste before adjusting. If the sauce is too spicy, a little additional cream or cheese can mellow it.
Recipe Variations
Extra-Spicy Cajun Sausage Penne
Use hot Italian sausage, extra Cajun seasoning, and crushed red pepper flakes.
Pepper Jack Cajun Pasta
Replace half or all of the cheddar with Pepper Jack for a creamy, spicy cheese sauce.
Cajun Chicken Penne
Swap sausage for bite-sized chicken breast or boneless chicken thighs.
Cajun Shrimp Pasta
Sauté seasoned shrimp separately and fold them into the finished creamy pasta.
Cajun Sausage Spinach Pasta
Add two large handfuls of baby spinach near the end for extra color and freshness.
Cajun Sausage Broccoli Pasta
Add small broccoli florets to the pasta water during the final few minutes of cooking.
Cajun Sausage and Corn Pasta
Sweet corn is a natural match for the spicy Cajun sauce and sweet chili flavor.
Smoky Gouda Version
Replace cheddar with smoked Gouda for a deeper smoky flavor.
Bacon Cajun Sausage Pasta
Add crispy bacon for another layer of smoky, salty flavor.
What to Serve With Cajun Sausage Penne
Garlic Bread
Crusty garlic bread is perfect for soaking up the creamy sauce.
Green Salad
A fresh salad with lettuce, cucumber, tomatoes, and vinaigrette adds acidity and freshness.
Roasted Broccoli
Roasted broccoli provides caramelized flavor and a slightly crisp texture.
Steamed Green Beans
Simple green beans provide a lighter side without overwhelming the main dish.
Corn on the Cob
Sweet corn complements the sweet chili and Cajun seasoning beautifully.
Cucumber Salad
A cool cucumber salad can help balance the warmth of the Cajun spices.
Garlic Roasted Vegetables
Roasted peppers, zucchini, and asparagus make excellent additions to this dinner.
Storage & Reheating
Refrigerator
Allow leftovers to cool before placing them in an airtight container.
Refrigerate for up to 3–4 days.
Microwave
Place one serving in a microwave-safe bowl.
Add a splash of milk, cream, or broth.
Heat in 30-second intervals, stirring between each interval until hot.
Stovetop
For several servings, warm the pasta in a skillet over low heat.
Add a little broth or cream and stir gently until the sauce becomes smooth again.
Freezer
Creamy cheese sauces can change texture after freezing and thawing, so refrigeration is recommended for the best results.
Common Mistakes to Avoid
Overcooking the Pasta
Penne should be al dente rather than soft. Overcooked pasta can become mushy when mixed with hot sauce.
Burning the Garlic
Garlic only needs a short cooking time. Burnt garlic can make the sauce bitter.
Using Too Much Cajun Seasoning
Cajun seasoning can quickly become overpowering, especially when combined with spicy sausage.
Boiling the Cream
Keep the sauce at low to medium-low heat once dairy is added.
Adding Cheese Over High Heat
High temperatures can cause cheese to become oily or grainy.
Forgetting to Save Pasta Water
A little pasta water can help you achieve a smooth, glossy sauce.
Making the Sauce Too Sweet
Sweet chili sauce already contains sugar. Add more sweetener only after tasting.
Overcrowding the Sausage
Give the sausage enough room to brown instead of steaming.
