-When you need a satisfying dinner without spending hours in the kitchen, this One-Pan Garlic Butter Cajun Sausage Penne is an excellent choice. It combines smoky sausage, tender penne, sweet bell peppers, tomatoes, garlic, and Cajun spices in one skillet for a hearty meal with big flavor and minimal cleanup.
The secret to this recipe is its simple cooking method. Instead of boiling the pasta separately, the penne cooks directly in the seasoned broth and tomato mixture. As it simmers, the pasta absorbs the flavors from the sausage, garlic, butter, and Cajun spices while releasing starch that helps create a naturally flavorful sauce.
The result is a comforting pasta dinner with a slightly spicy, savory, buttery finish. The tomatoes provide brightness, while bell peppers and onions add sweetness and texture. Fresh parsley and Parmesan bring everything together at the end.
This recipe is also easy to customize. You can use chicken or turkey sausage, increase the spice, add more vegetables, or finish it with a little cream or cheese for an even richer version.
The original recipe concept emphasizes a quick one-pan method, versatile sausage options, vegetables, and leftovers, making it particularly well suited to busy weeknights.

Ingredient Notes
Cajun Sausage
Sausage provides both protein and a significant amount of flavor. Smoked sausage, andouille, chicken sausage, or turkey sausage can all work.
If your sausage is already heavily seasoned, taste before adding additional salt.
Penne
Penne is ideal because its hollow center and ridged surface capture the tomato-butter sauce. Other short pasta shapes can be substituted.
Garlic
Fresh garlic gives the dish a much stronger aroma and flavor than dried garlic. Mince it finely so it distributes throughout the sauce.
Bell Peppers
Using two colors of peppers makes the skillet more colorful while adding sweetness and a subtle crunch.
Diced Tomatoes
Don’t drain the tomatoes. Their juices become part of the cooking liquid and help flavor the pasta.
Cajun Seasoning
Cajun blends vary in salt and heat. Start with a moderate amount, then adjust after tasting.
Ingredient Substitutions
Sausage
You can substitute the sausage with:
- Chicken sausage
- Turkey sausage
- Andouille sausage
- Italian sausage
- Smoked kielbasa
- Plant-based sausage
For a vegetarian option, use mushrooms, chickpeas, or a plant-based sausage alternative.
Pasta
If you don’t have penne, use:
- Rotini
- Rigatoni
- Fusilli
- Cavatappi
- Bow-tie pasta
- Elbow macaroni
Keep in mind that different pasta shapes may require slightly different cooking times.
Broth
Chicken broth works especially well, but vegetable broth can be used for a meat-free version.
Vegetables
Add or substitute:
- Zucchini
- Mushrooms
- Spinach
- Broccoli
- Corn
- Cherry tomatoes
Butter
For a dairy-free option, use additional olive oil or a dairy-free butter alternative.
Step-by-Step Instructions
Step 1: Slice and Season the Sausage
Slice the sausage into approximately ¼-inch rounds.
If desired, lightly season it with a small pinch of Cajun seasoning and black pepper.
Be careful not to over-season because sausage often contains plenty of salt and spices already.
Step 2: Brown the Sausage
Heat a large, deep skillet or Dutch oven over medium-high heat.
Add the olive oil.
Once hot, add the sausage slices in a single layer.
Cook for approximately 4–6 minutes, turning occasionally, until browned around the edges.
Remove the sausage and place it on a plate.
Don’t clean the skillet the browned bits will add flavor to the sauce.
Step 3: Sauté the Vegetables
Reduce the heat to medium.
Add the butter to the same skillet.
Once melted, add the diced onion and bell peppers.
Cook for approximately 4 minutes, stirring occasionally, until the vegetables begin to soften.
Step 4: Add the Garlic
Add the minced garlic.
Cook for approximately 30–45 seconds while stirring constantly.
The garlic should become fragrant but shouldn’t turn dark brown.
Step 5: Build the Cooking Liquid
Pour the diced tomatoes and their juices into the skillet.
Add the chicken broth.
Stir in:
- Cajun seasoning
- Smoked paprika
- Italian seasoning
- Red pepper flakes, if using
- Black pepper
Scrape the bottom of the skillet with a wooden spoon to loosen the browned bits left from the sausage.
Step 6: Add the Penne
Bring the mixture to a gentle boil.
Add the uncooked penne directly into the skillet.
Stir thoroughly so the pasta is submerged as much as possible.
Step 7: Simmer
Reduce the heat to medium-low.
Cover the skillet and cook for approximately 11–14 minutes.
Stir every few minutes to prevent the pasta from sticking to the bottom.
If the liquid is disappearing too quickly and the pasta isn’t tender, add ¼ cup of broth at a time.
Step 8: Return the Sausage
When the penne is almost tender, return the browned sausage to the skillet.
Stir everything together.
Continue cooking for another 2–3 minutes, or until the pasta is al dente and the sausage is heated through.
Step 9: Finish the Dish
Turn off the heat.
Stir in the chopped parsley and fresh lemon juice, if using.
Taste and adjust the seasoning.
For a richer finish, add a little extra butter or Parmesan.
Step 10: Rest Before Serving
Let the skillet rest uncovered for approximately 3–5 minutes.
This gives the sauce time to thicken slightly and allows the pasta to absorb any remaining liquid.
Finish with freshly grated Parmesan and extra parsley.
Serve hot.
Expert Tips
Brown the Sausage First
Don’t rush this step. Golden-brown edges create flavorful caramelization that carries throughout the dish.
Use a Deep Skillet
The pasta needs enough room to move around while it cooks. A deep 12-inch skillet or Dutch oven works particularly well.
Stir Regularly
One-pan pasta can stick more easily than pasta cooked in a large pot of water. Stir every few minutes.
Don’t Overcook the Penne
Aim for al dente pasta. It will continue cooking slightly while the skillet rests.
Taste Before Adding Salt
Cajun seasoning, sausage, broth, and Parmesan can all contain significant amounts of sodium.
Adjust the Liquid
If the pasta needs more cooking time but the skillet looks dry, add a little warm broth rather than turning up the heat.
Add Parmesan at the End
Parmesan is best used as a finishing ingredient rather than cooked aggressively into the sauce.
Recipe Variations
Creamy Cajun Sausage Penne
For a richer version, stir in ½ cup of heavy cream during the final few minutes of cooking. Add Parmesan after removing the skillet from the heat.
Spicy Cajun Pasta
Add:
- Extra Cajun seasoning
- Cayenne pepper
- Crushed red pepper
- Sliced jalapeños
- Your favorite hot sauce
Cajun Chicken Sausage Pasta
Use chicken sausage for a slightly lighter version while retaining the smoky flavor.
Cajun Shrimp Penne
Replace the sausage with peeled shrimp. Add the shrimp during the final few minutes so they don’t overcook.
Vegetable Cajun Penne
Add zucchini, mushrooms, spinach, broccoli, or corn for a vegetable-packed dinner.
Cheesy Cajun Pasta
Stir in shredded cheddar, Monterey Jack, or Pepper Jack just before serving.
What to Serve with Cajun Sausage Penne
Because this pasta is rich and flavorful, simple sides work best.
Fresh Green Salad
A crisp salad with cucumber, tomatoes, lettuce, and a tangy vinaigrette provides a refreshing contrast.
Garlic Bread
Warm garlic bread is perfect for soaking up any remaining tomato-butter sauce.
Roasted Broccoli
Roasted broccoli adds a slightly crispy texture and pairs beautifully with Cajun seasoning.
Green Beans
Steamed or roasted green beans provide a light vegetable side.
Corn on the Cob
Sweet corn complements the smoky, spicy flavors of Cajun sausage.
Coleslaw
A cool, crunchy slaw can balance the warmth and spice of the pasta.
Storage & Reheating
Refrigerator
Transfer cooled leftovers to an airtight container.
Store in the refrigerator for 3–4 days.
Freezer
For longer storage, freeze individual portions in airtight freezer-safe containers for up to 2–3 months.
The pasta may soften slightly after thawing, but the flavor will remain enjoyable.
Microwave
Place a portion in a microwave-safe bowl.
Add a tablespoon or two of broth or water.
Cover loosely and heat in short intervals, stirring between each interval.
Stovetop
Place leftovers in a skillet over medium-low heat.
Add a splash of broth and stir occasionally until thoroughly warmed.
Avoid high heat, which can dry out the pasta.
Common Mistakes to Avoid
Overcooking the Pasta
Penne can quickly go from al dente to mushy. Start checking it before the recommended cooking time is finished.
Not Stirring
Pasta sitting against the bottom of the skillet can stick or burn. Stir regularly.
Adding Too Much Cajun Seasoning
Cajun blends vary considerably. Start with less and increase after tasting.
Skipping the Sausage Browning
Browning is what gives the sausage its best texture and adds flavor to the skillet.
Draining the Tomatoes
The tomato juices are part of the cooking liquid. Keep them in the pan.
Using Too Much Liquid
The pasta needs enough broth to cook but shouldn’t be swimming in liquid at the end. Add additional broth gradually if needed.
Serving Immediately
A short resting period allows the sauce to settle and thicken.
