Ingredients for Cajun Spaghetti
Exact measurements for spaghetti with sausage and peppers can be found in the recipe card.
- Spaghetti: I make this recipe using spaghetti, but any shape of pasta will work well. Try experimenting with rotini, farfalle, or penne.
- Andouille Sausage: A smoked sausage made from pork, garlic, and spices. It's popular in Louisiana Cajun cuisine and has a slightly spicy taste.
- Butter
- Mushrooms
- Bell Pepper: I love using red bell pepper in pasta, but any color will work well.
- Garlic: Fresh is always best!
- Shallot: Ideal for making sauces because of their mild, delicate flavor. Onions are a good substitute for shallots, but keep in mind that onions will have a stronger flavor.
- Flour: The flour is crucial to thickening this Cajun spaghetti sauce recipe.
- Chicken Broth
- Heavy Cream
- Parmesan: Shred fresh parmesan for the best taste and consistency.
- Cajun Seasoning: A blend of spices such as: paprika, garlic powder, cayenne, and thyme. I use this store-bought Cajun seasoning.
How to Make Cajun Spaghetti
Spaghetti and sausage is a delicious combination. This Cajun spaghetti recipe will become a fast favorite in your kitchen!
Step 1: Cook spaghetti according to package directions. Slice andouille sausage into ¼ inch coins and brown in a large skillet on medium heat for 8 minutes, stirring occasionally to ensure all sides get browned. Set aside.
Step 2: Melt butter in a medium-sized saucepot. Sauté bell peppers, mushrooms, and shallots on medium heat for 3-4 minutes until softened. Then add garlic and Cajun seasoning and cook an additional 1 minute.
Step 3: Add flour to the saucepot in 1 tablespoon increments, stirring in between each tablespoon. Once all the flour is incorporated, cook for 1 minute. Then, slowly pour in chicken broth while stirring continuously so the flour doesn't clump.
Step 4: Pour heavy cream into the saucepot and bring to a boil for 1 minute.
Step 5: Stir in freshly grated parmesan cheese and simmer for 10 minutes. Note: you may need to simmer an additional 5 minutes if the sauce isn't thick enough for your liking.
Step 6: Add the cooked andouille sausage to the sauce and heat through. Toss Cajun cream sauce with your pasta of choice. Serve Cajun sausage spaghetti immediately topped with shredded parmesan, if desired.
Expert Tips
- Slice andouille sausage and brown it in a skillet before adding it to the sauce to boost flavor.
- Flour, a thickening agent, is one of the most important ingredients to making this creamy Cajun spaghetti sauce recipe. Stir after adding each tablespoon of flour and let it cook for 1 minute before adding the chicken broth in slowly.
- If the sauce isn't thickening, you may need to let it simmer an extra 5-10 minutes. The sauce will thicken upon standing.
FAQs
Although andouille sausage has a kick of heat, it's not overly spicy.
You can use kielbasa or smoked sausage as a substitute for andouille sausage.
Both flour and allowing the pasta sauce to simmer long enough will help reduce and thicken it. Before adding liquid, sauté vegetables and garlic with flour for 1 minute. If you have already added the liquid, add more parmesan cheese to help thicken the sauce.
Swaps & Substitutions
- For a spicier sauce, add a pinch of red pepper flakes, extra cayenne powder, or a dash of hot sauce.
- Change up the protein or add more protein. We like to add chicken or shrimp to this Cajun spaghetti with sausage.
- If you don't have andouille sausage, you can use kielbasa or smoked sausage as a substitute.
Storage & Reheating
In my opinion, pasta is best hot and fresh! If you have leftovers, store them in an airtight container in the refrigerator for up to 4 days (my favorite storage containers).
To reheat Cajun spaghetti, you can use the microwave or stovetop. Microwave individual servings in a microwave safe bowl in 30 second increments stirring in between until the desired temperature is reached.
On the stovetop, reheat pasta in a skillet on medium heat. You may need to add a splash of broth or cream to loosen the sauce.
