Ingredients Needed

Here’s what you’ll need to create this delicious Crockpot Cajun Chicken Pasta:
1 pound boneless skinless Chicken Breast (cut into bite sized pieces)
1 1/2 tablespoons Cajun Seasoning
1 Red Pepper (cut into strips)
1 Yellow Pepper (cut into strips)
1 Red Onion (sliced)
2 Garlic Cloves (minced)
2 cans Chicken Broth
1 can Fire Roasted Tomatoes
3/4 cup Heavy Cream
12 ounces Penne Pasta
2 teaspoons Cornstarch
1 tablespoon Water
3/4 cup Parmesan Cheese (shredded )
Salt and Pepper (to taste)
Sprinkle of Parsley
Ingredient Notes & Substitutions
Cajun Seasoning: You can use store-bought or homemade Cajun seasoning. Store-bought blends like Tony Chachere’s or Slap Ya Mama are convenient, but heat levels can vary by brand. Adjust the amount to your preference. For a homemade option, see the recipe later in this article.
Chicken: Chicken thighs can be used as a substitute for chicken breast. They offer a richer flavor and are more forgiving in terms of overcooking.
Pasta: Penne pasta works best in this recipe, but other short pasta shapes like rotini or farfalle can be substituted. If you prefer fettuccine or pappardelle, consider cooking the pasta separately and adding it at the end.
Heavy Cream: For an even creamier sauce, you can add cream cheese as an alternative (reinforcing the unique twist). Note that using half-and-half will result in a thinner sauce.
Dairy-Free: Coconut milk or cashew cream can be used as dairy-free alternatives to heavy cream. Nutritional yeast can replace parmesan cheese.
Gluten-Free: Gluten-free pasta can be used to make this dish gluten-free.

How to Make Crockpot Cajun Chicken Pasta
Follow these simple steps to create a creamy, flavorful Crockpot Cajun Chicken Pasta:
Step 1: Prep the Vegetables
Prep your veggies first. Cut peppers into strips, slice the onion and mince the garlic (or use store-bought jar of minced garlic). The aroma of the fresh vegetables is already enticing!
Step 2: Prepare the Chicken
Next, cut chicken into cubes. Ensure chicken pieces are similar in size for even cooking.
Step 3: Combine Ingredients in Slow Cooker
Add diced chicken breast to an 8 quart slow cooker. Add Cajun seasoning, peppers, onions and garlic. The vibrant colors of the peppers and onions mix with the fragrant Cajun spice to coat the chicken.
Step 4: Add Liquids
Pour in the chicken broth, tomatoes and 1/2 cup heavy cream. The broth and tomatoes create a rich base for the sauce.
Step 5: Slow Cook the Chicken
Cook on high for 3 hours or until the chicken is cooked. The chicken should be easily shredded with a fork when done.
Step 6: Add Pasta and Cream Cheese
About 30-40 minutes before done, add in the uncooked pasta and stir. Stir well to ensure the pasta is submerged in the liquid. This is where you incorporate the cream cheese, cut into cubes.
Step 7: Thicken the Sauce
Add the cornstarch and water. Stir again. This slurry will help thicken the sauce.
Step 8: Cook the Pasta
Put the lid back on and stir every 10 minutes until pasta is cooked. Stirring prevents the pasta from sticking together or to the bottom of the slow cooker. Ensure pasta is al dente.
Step 9: Finish the Dish
Once done add in the remaining 1/4 cup heavy cream, Parmesan cheese, salt and pepper to taste. Stir. The sauce will now be thick and creamy, with a rich, cheesy flavor.
Step 10: Garnish and Serve
Top with parsley (optional). The fresh parsley adds a pop of color and freshness.
Cajun Seasoning: Store-Bought vs. Homemade
Cajun seasoning is a key ingredient in this dish, and you have the option of using store-bought or making your own. Store-bought blends are convenient, but they can vary significantly in heat and salt content. Be sure to check the label and adjust the amount accordingly.
Making your own Cajun seasoning allows you to customize the heat level and control the ingredients. Here’s a basic recipe:
- 2 tablespoons paprika
- 1 tablespoon cayenne pepper
- 1 tablespoon garlic powder
- 1 tablespoon onion powder
- 1 tablespoon dried oregano
- 1 tablespoon dried thyme
- 1 tablespoon black pepper
- 1 tablespoon salt
Combine all ingredients and store in an airtight container.
Adjusting Liquid Ratios for Your Slow Cooker
Slow cookers can vary in how much liquid they evaporate during cooking. Older models tend to evaporate less liquid than newer ones. To ensure your pasta isn’t too dry or soupy, it’s important to adjust the liquid ratios as needed.
Start with the recommended amount of chicken broth (2 cans). If you notice the sauce is becoming too thick during cooking, add a splash of chicken broth or water. Conversely, if the sauce is too thin, remove the lid during the last hour of cooking to allow some of the liquid to evaporate.
Using a slow cooker liner can also reduce liquid evaporation, as it creates a more sealed environment. You can read more about slow cooker liners and how they work on Allrecipes.
Pro Tips & Troubleshooting
Pro Tips
Boil your pasta on the stove top and add in once your sauce is thickened for a quicker meal.
Cook on low for 4-5 hours for a more hands-off approach.
Stir the pasta every 10 minutes to prevent sticking.
Use a meat thermometer to ensure the chicken is cooked through to an internal temperature of 165°F (74°C). You can find guidelines for safe minimum internal temperatures for cooking different meats at FoodSafety.gov.
Add a squeeze of lemon juice at the end to brighten the flavors.
If the sauce is too thick, add a splash of chicken broth or heavy cream.
Grate the Parmesan cheese fresh for the best flavor.
Don’t overcook the pasta; it should be al dente. It will continue to cook slightly in the sauce.
Common Mistakes to Avoid
Overcooking the pasta, which can result in a mushy dish.
Using too much Cajun seasoning, which can make the dish too spicy.
Not stirring the pasta frequently enough, which can cause it to stick together.
Adding the cream cheese too early, which can curdle the sauce.
Using low-fat or fat-free cream cheese, which won’t melt as smoothly.
Skipping the cornstarch slurry, which can result in a thin sauce.
Not tasting and adjusting the seasoning at the end.
Serving & Storage
Serving Ideas
Serve with crusty garlic bread for dipping in the creamy sauce.
Offer a side salad with a light vinaigrette to balance the richness of the pasta.
Garnish with extra Parmesan cheese and fresh parsley.
Consider serving with a sprinkle of red pepper flakes for added heat.
Storage and Make-Ahead
Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
Reheat gently in the microwave or on the stovetop. Add a splash of chicken broth or water if the sauce is too thick.
This dish can be made ahead of time and refrigerated for up to 24 hours before cooking. Add the pasta just before cooking.
Freezing is not recommended due to the cream-based sauce, which may separate upon thawing.
