Smoky andouille sausage, sweet red bell pepper, tomatoes, Parmesan, and tender penne come together in this Andouille Sausage Pasta for a hearty dinner with very little cleanup. Everything cooks in the same large skillet, so the pasta absorbs the savory sausage flavor as it simmers instead of being boiled separately. Milk and Parmesan soften the acidity of the tomatoes and give the finished sauce a creamy texture without requiring heavy cream.
This easy andouille sausage pasta is especially useful on busy weeknights: the ingredient list is short, the cooking method is straightforward, and most of the work happens in one pan. Depending on the sausage you choose, it can range from pleasantly smoky to distinctly spicy, making it easy to adjust for your household.
Why This One-Pot Pasta Works
Cooking pasta directly in the sauce does two useful things. First, it eliminates the extra pot and colander normally required for pasta night. More importantly, the starch released from the penne stays in the skillet. That starch helps the milk, tomatoes, and Parmesan form a sauce that clings to every piece of pasta.
Andouille provides much of the dish’s seasoning. Its smoky, garlicky character flavors the bell pepper and cooking liquid, while tomatoes provide acidity to balance the richness. Parmesan added at the end gives the sauce a savory finish.
Because brands of pasta and skillet dimensions vary, the amount of water deserves a little flexibility. The two cups in the ingredient list are a starting point; add only enough liquid to barely cover the pasta.
Ingredients You’ll Need
Andouille sausage: Cut 1 pound of andouille into approximately 1-inch pieces. Many packaged andouille sausages are sold fully cooked, making them convenient for quick dinners. Check your package so you know what type you’re using.
Penne pasta: A 16-ounce box works well because the tubular shape catches the creamy tomato sauce. Similar short pasta shapes can also work, although cooking times and the amount of liquid needed may vary.
Red bell pepper: One diced red pepper provides color, sweetness, and a fresh contrast to the smoky sausage.
Crushed tomatoes: One 14.5-ounce can creates the tomato base. Crushed tomatoes blend into the cooking liquid more readily than diced tomatoes.
Milk: One cup makes this creamy andouille sausage pasta smooth without producing an especially heavy sauce. Whole or 2% milk will give the richest results.
Parmesan: Half a cup of Parmesan finishes the sauce and adds a salty, nutty flavor. Finely grated cheese melts most smoothly.
Garlic and Italian seasoning: Two teaspoons of minced garlic and one tablespoon of Italian seasoning add aromatic flavor to the tomato base.
Salt and black pepper: The recipe calls for 1 teaspoon of each, but sausage and Parmesan can both contain substantial salt. Taste before adding extra salt, particularly when using a strongly seasoned sausage.
Water: Start with 2 cups and adjust as necessary so the pasta is just barely covered before simmering.
How to Make Andouille Sausage Pasta
Begin with a large, deep skillet that has a lid. Add the sliced andouille and diced red bell pepper, then cook them over medium heat. Let the sausage make good contact with the skillet so the cut surfaces can brown. At the same time, the pepper will begin to soften.
Stir in the dry penne, milk, crushed tomatoes, Italian seasoning, minced garlic, salt, and black pepper. Pour in the water, using just enough to barely cover the pasta. Stir thoroughly so pasta isn’t trapped dry above the liquid.
Cover the skillet and maintain a gentle simmer over medium heat for about 10 minutes. Stir during cooking, especially as the liquid reduces, to keep the pasta from sticking to the bottom or clumping together.
Once the penne is tender, remove the lid. If there is still a lot of thin liquid in the skillet, let it simmer uncovered briefly. Stir in the Parmesan until it melts and the sauce coats the pasta. Serve immediately while the sauce is hot and creamy.
Tips for a Creamy, Flavorful Sauce
The key to a successful one pot andouille sausage pasta is controlling the liquid rather than blindly adding more. Skillets with a wider surface area lose moisture faster, and different pasta brands absorb different amounts of water. If the pan looks dry while the penne is still firm, add a small splash of hot water and continue cooking.
Keep the heat moderate after adding the milk. A controlled simmer cooks the pasta while allowing the sauce to thicken gradually. Aggressive boiling can cause dairy-based sauces to separate or scorch on the bottom.
Add the Parmesan only after the pasta is tender. Stirring finely grated cheese into the finished sauce helps it melt evenly instead of sticking to the skillet.
Finally, taste before adjusting the seasoning. Andouille and Parmesan bring plenty of savory flavor on their own, and the exact salt level differs considerably between brands.
If one-pan pasta dinners are your preferred kind of weeknight cooking, this simple creamy chicken broccoli pasta is another comforting combination to keep in your dinner rotation.
How Spicy Is Andouille Sausage Pasta?
Andouille is strongly seasoned, but its heat level varies by producer. Some sausages are predominantly smoky and garlicky, while others have a noticeable chile kick. The recipe doesn’t add cayenne or hot sauce, so the sausage determines most of the heat.
For a spicy andouille sausage pasta, choose a hot andouille or add a small amount of cayenne or Cajun seasoning. Start conservatively because you can always increase the heat at the table.
For a milder dinner, select a mild smoked sausage in place of traditional andouille. That changes the characteristic Cajun-inspired flavor somewhat, but the cooking method remains the same.
Easy Variations
For a more pronounced creamy Cajun sausage pasta flavor, replace some or all of the Italian seasoning with Cajun seasoning. Because many commercial Cajun blends contain salt, reduce the recipe’s added salt and season to taste at the end.
You can also add diced onion along with the bell pepper or use a combination of red, yellow, and green peppers. For extra richness, a small splash of cream can be stirred in at the end, although the milk and Parmesan already produce a creamy sauce.
Other short pasta shapes, such as rigatoni, ziti, or rotini, are reasonable substitutes for penne. Watch the texture rather than relying on the original 10-minute cooking time, since different shapes may need more or less time.
What to Serve With Cajun Andouille Sausage Pasta
This cajun andouille sausage pasta is substantial enough to serve as the main course. A crisp green salad or simply seasoned roasted vegetables make useful sides because they provide freshness without competing with the smoky tomato sauce.
Garlic bread is another natural choice, particularly if you want something for catching the sauce left on the plate. For a lighter meal, keep the accompaniments vegetable-focused and let the sausage pasta remain the centerpiece.
Storage, Reheating, and Make-Ahead Tips
Transfer leftovers to shallow containers and refrigerate them promptly rather than leaving the skillet at room temperature for an extended period. The USDA guidance for safely handling leftovers recommends refrigerating leftovers within two hours and using refrigerated leftovers within three to four days.
The pasta will absorb more sauce as it rests. When reheating, add a splash of milk or water and stir as the pasta warms to loosen the sauce. The USDA recommends reheating leftovers to an internal temperature of 165°F.
You can prepare the sausage and bell pepper in advance and refrigerate them, but this dish has its best pasta texture when cooked shortly before serving. Freezing the finished pasta is possible, although dairy-based sauce and cooked pasta may lose some of their original texture after thawing.
Frequently Asked Questions
Can I use precooked andouille sausage?
Yes. Fully cooked andouille is particularly convenient here because it only needs to brown and heat through before the remaining ingredients are added. Always check the product label because sausage products can differ.
Why is my pasta still firm after 10 minutes?
Pasta cooking times vary, and one-pot recipes are also affected by skillet size and heat level. If the penne is still firm and most of the liquid has disappeared, add a few tablespoons of hot water, cover, and continue simmering until tender.
Can I make this pasta without milk?
You can replace the milk with additional water or broth, but the sauce won’t have the same creamy character. If dairy is the concern, an appropriate unsweetened dairy-free milk may work, although its flavor and thickening behavior can differ.
Can I add Cajun seasoning?
Absolutely. Cajun seasoning is a simple way to make the dish more assertively Cajun-inspired. Check whether your blend contains salt before adding the full teaspoon of salt called for in the recipe.
How do I thicken a sauce that looks too watery?
Once the pasta is tender, remove the lid and simmer briefly so excess liquid can evaporate. Then stir in the Parmesan. The pasta starch and cheese will continue to thicken the sauce, especially as it cools slightly.
