Ingredients for One Pot Chicken Pasta

Below are the core ingredients used in this recipe. Exact measurements and full instructions are included in the recipe card further down.

• Boneless, skinless chicken breasts – diced into bite-sized pieces.
• Cajun seasoning – for a smoky, spicy kick.
• Onion and red bell pepper – sautéed for sweetness and depth.
• Dried penne pasta – sturdy pasta that holds up in the sauce.
• Chicken broth – cooks the pasta and adds savory flavor.
• Rotel (diced tomatoes with green chiles) – for brightness and mild heat.
• Milk or heavy cream – stirred in at the end for a creamy finish.
• Parmesan or mozzarella (optional) – sprinkle on top before serving.

Portioning, Freezing, and Meal Prep

• Serving size: The recipe yields about 4 servings. It’s easy to halve for two people.
• Freezing: The assembled dish is best eaten fresh or refrigerated; cream-based pasta can separate if frozen. Instead, you can dice the chicken and freeze it raw, and then thaw and cook when ready.
• Meal prep tip: Chop the onion and pepper ahead of time to speed up dinner on busy nights.

Step-by-Step Instructions

Simple skillet steps bring this dish together quickly. Follow the numbered steps for an easy weeknight meal.

1. Season the chicken: Toss diced chicken with Cajun seasoning so each piece is coated.
2. Brown the chicken: Heat a skillet with a little oil (cast iron works well). Add the chicken in a single layer and let it sear undisturbed until the edges turn opaque and begin to brown, then turn and finish cooking.
3. Sauté the vegetables: Add diced onion and red bell pepper to the pan. Their moisture helps deglaze the pan and lift any flavorful browned bits.
4. Add pasta and liquids: Stir in the dried penne, chicken broth, and a can of Rotel (including the juices). Bring the mixture to a boil.
5. Simmer: Reduce heat to low, cover, and simmer for about 10 minutes, stirring occasionally, until the pasta is tender and most of the liquid is absorbed.
6. Finish with cream: Stir in milk or cream to create a silky sauce. Heat through but do not boil vigorously to avoid breaking the cream.
7. Serve: Sprinkle with grated Parmesan or shredded mozzarella if you like, and serve hot.

Cooking Tips for Cast Iron

Cooking this recipe in a cast iron skillet gives excellent browning and a deep flavor, but a few pointers help get the best results:

• Preheat the pan: Warm the skillet and add a bit of oil so the chicken sizzles on contact.
• Don’t move the chicken too soon: Let the pieces develop a sear before flipping to prevent sticking.
• Use the veggies to deglaze: Onions and peppers release liquid that helps lift browned bits from the pan for extra flavor.
• Stir occasionally while simmering: Keep the heat low and stir so pasta cooks evenly and nothing sticks to the bottom.
• Care for your skillet: After use, dry it thoroughly and rub a light coat of oil to protect the seasoning.

Substitutions and Variations

• Add sliced smoked sausage with the vegetables for a heartier version.
• Swap or add vegetables such as sliced mushrooms, zucchini, or spinach.
• For more heat, try a tablespoon of Southwest seasoning plus a pinch of cayenne.
• Use heavy cream instead of milk for an extra-rich sauce.

What to Serve with Cajun Chicken Pasta

This dish stands well on its own but also pairs nicely with lighter sides that balance the spice and creaminess:

• A fresh side salad with a tangy vinaigrette.
• Warm garlic bread or crusty bread to soak up the sauce.
• Roasted or steamed vegetables to add color and nutrients.
