📖Why My Recipe Works
- Pasta Water- During my recipe testing, adding chicken stock was too salty, and using reserved pasta water gave this recipe a better flavor.
- Fire Roasted Tomatoes- We're skipping diced tomatoes and using fire-roasted tomatoes to enhance the smoky flavor.
🧾Ingredient Notes
- Spaghetti- If you use gluten-free pasta, I recommend Jovial Spaghetti. You can also substitute spaghetti with fettuccine, linguine, penne pasta, or even bowtie pasta.
- Andouille Sausage- If you don't have andouille, you can use other smoked sausages like Italian sausage, chorizo, or kielbasa.
- Cajun Trinity + Mushrooms- We're adding mushrooms to the Cajun trinity (onions, bell pepper, and celery). Use cremini or button mushrooms.
- Garlic- If you don't have fresh garlic, skip it. There is garlic powder in the Cajun seasoning.
- Cajun Seasoning- Use store-bought Cajun seasoning, or better yet, make my homemade Cajun seasoning blend.
- Fire-roasted Tomatoes- Substitute with crushed tomatoes or diced tomatoes.
- Heavy Cream- For a lighter version, use half and half or coconut milk for dairy-free.
- For more heat, add red pepper flakes or cayenne pepper.
⏲️How to Make Cajun Spaghetti
- Cook the sausage for 3 minutes per side to develop a deep, caramelized crust. Remove the sausages but don't wipe the pan, the browned bits left behind add flavor.
- Add the fresh veggies. Keep stirring until most of the moisture evaporates and the mushrooms start to brown. We're adding the garlic last because we don't want it to burn. Then, add the Cajun seasoning and stir to coat the vegetables evenly.
- Add the fire-roasted tomatoes and reserved pasta water. Pasta water contains starch, which helps thicken the sauce. Start with a small splash and add more later as needed.
- Stirring in the cream after turning off the heat prevents it from curdling and keeps the sauce smooth and rich. If the sauce is too thick, add more pasta water.
- Add the cooked spaghetti and stir to combine. Serve with parmesan and minced parsley, and enjoy!
👩🏻🍳 Expert Tips
- Since the pasta will finish cooking in the sauce, undercook it by about 1 minute to prevent it from getting mushy.
- Cajun seasoning can be salty, depending on the brand. Start with a small amount and adjust with more seasoning or a pinch of salt before serving.

🌡️Storing Leftovers
Store leftover pasta in an airtight container and refrigerate for up to 4 days or freeze for up to 2 months. Reheat in the microwave for 1-2 minutes (30-second intervals, stirring in between), or on the stovetop over medium heat. Add a splash of cream or milk to loosen up the sauce. If reheating from frozen, let it thaw overnight in the fridge, then reheat using the stovetop or microwave method.Equipment
