How to Make One Pot Cajun Chicken Pasta
This recipe comes together in a few simple steps. No complicated techniques—just straightforward cooking.
1. Cook the Chicken
Heat oil in a large pot over medium-high heat. Toss the chicken with part of the Cajun seasoning, then cook until golden and fully cooked through. Remove and set aside to keep warm.
2. Sauté the Vegetables
In the same pot (don’t clean it—that’s flavor!), add a bit more oil if needed. Toss in the bell peppers and onion, cooking until slightly softened. Add garlic and remaining Cajun seasoning and cook briefly until fragrant.
3. Add Liquids and Pasta
Pour in the chicken broth, tomatoes, and part of the cream. Bring everything to a boil, then stir in the pasta.
4. Cook Until Tender
Let the pasta cook directly in the sauce, stirring occasionally to prevent sticking. This step allows the pasta to absorb all those amazing flavors.
5. Thicken the Sauce
Add the cornstarch slurry and cook for another minute or so until the sauce thickens slightly.
6. Finish the Dish
Turn off the heat and stir in the remaining cream, parmesan cheese, parsley, and cooked chicken. Season to taste.
7. Serve and Enjoy
Serve warm, creamy, and fresh. You’ll immediately notice how rich and comforting this dish is.
Variations You Can Try
One of the best things about this One Pot Cajun Chicken Pasta is how flexible it is.
- Swap the protein:
Try shrimp (quick-cooking!) or smoked sausage for a different twist. - Make it vegetarian:
Skip the chicken and load it up with zucchini, mushrooms, spinach, or corn. - Make it extra creamy:
Add a bit of cream cheese at the end for a tangy, richer sauce. - Adjust the spice level:
Use less Cajun seasoning for mild flavor or add chili flakes for extra heat.
What to Serve With Cajun Chicken Pasta
This dish is hearty on its own, but if you want to round out the meal:
