Why Make This One-Pot Creamy Cajun Chicken Pasta 20 Minute Dinner

You should make this recipe because it eliminates the most annoying part of cooking: the cleanup. With everything happening in one skillet, you save time and energy. The flavors are deeply layered because the pasta absorbs the Cajun spices and chicken juices as it cooks. It is a high-protein, filling meal that rivals any Italian-American bistro, yet it costs a fraction of the price to make at home. Plus, you can easily adjust the heat level to suit your personal preference.

Ingredients

• 1 lb boneless skinless chicken breasts, cut into bite-sized pieces
• 2 tablespoons Cajun seasoning (divided)
• 2 tablespoons olive oil
• 1 red bell pepper, sliced
• 1 yellow onion, diced
• 3 cloves garlic, minced
• 8 oz penne pasta (dry)
• 2 cups chicken broth
• 1 cup heavy cream
• 1/2 cup grated Parmesan cheese
• 1/2 teaspoon smoked paprika
• Salt and pepper to taste
• Fresh parsley or sliced green onions for garnish

Directions

Step 1: Season and Sear the Chicken

Place the chicken pieces in a bowl and toss them with one tablespoon of the Cajun seasoning until evenly coated. Heat the olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the chicken and cook for 3-5 minutes until browned on all sides. You do not need to cook it all the way through yet. Remove the chicken from the pan and set it aside on a plate.

Step 2: Sauté the Aromatics and Vegetables

In the same skillet, add the sliced bell peppers and diced onions. Sauté for about 3 minutes until the vegetables begin to soften. Stir in the minced garlic and cook for another 30 seconds until fragrant. If the pan looks dry, add a tiny splash of broth to scrape up the flavorful brown bits (fond) from the bottom.

Step 3: Simmer the Pasta

Add the dry penne pasta, chicken broth, heavy cream, the remaining tablespoon of Cajun seasoning, and smoked paprika to the skillet. Stir well to combine. Bring the liquid to a gentle boil, then reduce the heat to medium-low. Cover the pan and simmer for 10-12 minutes, stirring occasionally to prevent the pasta from sticking to the bottom. The pasta is ready when it is al dente and the liquid has reduced into a thick sauce.

Step 4: Combine and Finish

Add the cooked chicken back into the skillet along with any juices from the plate. Stir in the grated Parmesan cheese and continue to cook for 1-2 minutes until the chicken is heated through and the cheese has melted into the sauce. If the sauce is too thick, add a tablespoon of water or broth. Garnish with fresh parsley or green onions and serve immediately.

Expert Tips for Perfect One-Pot Creamy Cajun Chicken Pasta 20 Minute Dinner

To ensure success, use a heavy-bottomed skillet to prevent the cream from scorching. Always stir the pasta every few minutes; since there is less liquid than a traditional boil, the starch can cause the noodles to clump. If you prefer a milder flavor, look for a “low sodium” or “mild” Cajun spice blend, as some commercial brands can be very salt-heavy and spicy. Finally, use room temperature heavy cream to prevent the sauce from curdling when it hits the hot pan.

Delicious Variations

You can easily customize this dish to fit your cravings. Swap the chicken for large shrimp for a seafood twist; just sear the shrimp for 2 minutes and add them back at the very end. For a vegetarian version, replace the chicken with sliced mushrooms and use vegetable broth. If you want more greens, stir in two cups of fresh baby spinach during the last minute of cooking until it wilts. You can also use smoked sausage or andouille for an even more authentic Louisiana flavor profile.

Frequently Asked Questions

Can I use a different type of pasta?
Yes, short pasta shapes like rotini, bow ties, or rigatoni work best for one-pot meals because they cook evenly and hold the sauce well. Avoid long noodles like spaghetti as they tend to tangle and cook unevenly in a shallow pan.

Is this dish very spicy?
The spice level depends entirely on your Cajun seasoning. You can start with half the recommended amount and add more at the end if you want more heat. Adding a pinch of cayenne pepper will also kick it up a notch.

Can I use milk instead of heavy cream?
You can use whole milk or half-and-half, but the sauce will be thinner. If you use milk, you may need to simmer the sauce a bit longer uncovered at the end or add a small cornstarch slurry to help it thicken.

How do I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk or water to loosen the sauce, as the pasta will absorb the moisture while sitting in the fridge.

Can I make this dairy-free?
Yes, you can substitute the heavy cream with full-fat canned coconut milk and use a dairy-free Parmesan alternative or nutritional yeast. The flavor will change slightly but will still be delicious and creamy.
