Ingredients
- 1 lb boneless, skinless chicken breasts, cubed
- 8 oz spaghetti noodles
- 1 tablespoon olive oil
- 1 medium onion, diced
- 1 bell pepper, diced (red or green)
- 3 cloves garlic, minced
- 2 tablespoons Cajun seasoning
- 1 can (14.5 oz) diced tomatoes, undrained
- 1 cup chicken broth
- 1/2 cup heavy cream
- 1 cup shredded cheddar cheese
- 1/4 cup grated Parmesan cheese
- Fresh parsley for garnish
- Salt and pepper to taste
Step-by-Step Instructions
Step 1: Heat olive oil in a large skillet or Dutch oven over medium-high heat. Add cubed chicken and cook until browned on all sides, about 5-6 minutes. Remove chicken and set aside.
Step 2: In the same skillet, add diced onion and bell pepper. Cook until softened, about 3-4 minutes. Add minced garlic and cook for another minute until fragrant.
Step 3: Sprinkle Cajun seasoning over the vegetables and stir to combine. Return the cooked chicken to the skillet.
Step 4: Add diced tomatoes with their juices and chicken broth. Bring to a simmer, then add the spaghetti noodles, making sure they’re submerged in the liquid.
Step 5: Cover and simmer for 12-15 minutes, stirring occasionally, until pasta is cooked al dente and most liquid is absorbed.
Step 6: Stir in heavy cream and both cheeses until cheese is melted and sauce is creamy. Season with salt and pepper to taste.
Step 7: Garnish with fresh parsley and serve immediately. For another delicious creamy pasta option, check out our Marry Me Chicken Pasta.
Expert Tips for Perfect Cajun Chicken Spaghetti
Adjust the Heat: Cajun seasoning can vary in spiciness. Start with 1 tablespoon and add more to taste. For milder flavor, use half the amount and add more after tasting.
Don’t Overcook the Pasta: The spaghetti will continue to cook slightly after you turn off the heat, so aim for al dente texture when testing.
Customize Your Veggies: Add sliced mushrooms, corn, or diced celery along with the peppers for extra flavor and nutrition.
Make it Ahead: This dish reheats beautifully. Store leftovers in an airtight container for up to 3 days. If you enjoy make-ahead meals, our Instant Pot Chicken and Rice Dinner is another great option.
Creamy Sauce Perfection: For an extra creamy texture, stir in an additional 1/4 cup of cream at the end. The sauce will thicken as it cools.
