One-Pot Chicken Cajun Pasta

Okay, here’s a little kitchen secret I only tell people I like: one-pot meals become my superhero when I need big flavor with tiny cleanup. I learned this trick while hustling through weeknights with a hungry family — sear the chicken hard, toss everything into one pan, and let pasta soak up all that spiced, creamy goodness. This One-Pot Chicken Cajun Pasta gives you peppery heat, silky cream, and a little char on the chicken that sings in every bite. If your house smells like a Creole cafe after 20 minutes, you’re doing it right.

The sauce finishes silky, the pasta finishes al dente, and the whole kitchen hums like a Friday night.

Ingredients

For the Main Dish:

• 1 lb boneless, skinless chicken breasts, cut into 1-inch pieces
• 12 oz penne or rigatoni pasta (about 3 cups dry)
• 2 tbsp butter
• 1 tbsp olive oil
• 1 medium yellow onion, thinly sliced
• 1 red bell pepper, thinly sliced
• 3 cloves garlic, minced
• 2 tbsp Cajun seasoning (store-bought or homemade)
• 1 tsp smoked paprika
• 1/2 tsp black pepper
• 3 cups low-sodium chicken broth
• 1 cup heavy cream
• 1 (14.5 oz) can diced tomatoes, drained slightly (optional for a touch of acidity)
• Salt to taste (start with 1/2 tsp)

For the Sauce / Garnish (if applicable):

• 1/2 cup grated Parmesan (plus extra for serving)
• 2 tbsp chopped fresh parsley or green onions
• Fresh lemon wedges (for squeezing at the table)

How I Make It

Step 1:

Heat a large, heavy-bottomed skillet over medium-high heat and add 1 tbsp olive oil plus 2 tbsp butter. When the butter melts and starts to foam, pat the chicken dry and toss it with 2 tbsp Cajun seasoning and 1 tsp smoked paprika. Add the chicken in a single layer and let it sear without moving for 3–4 minutes until you get deep, golden edges and a slightly crisp sound. Flip and cook another 2 minutes until nearly cooked through. Remove chicken to a plate (it will finish cooking later).

Step 2:

Lower heat to medium and add the sliced onion and red bell pepper to the same pan. You’ll hear a happy sizzle; scrape up those brown bits with a wooden spoon — that’s flavor. Cook for 4–5 minutes until soft and fragrant, then stir in the minced garlic and cook 30 seconds until it smells bright and toasty. Return the chicken to the pan.

Step 3:

Pour in 3 cups chicken broth and scrape the bottom of the pan. Stir in the 12 oz pasta and the drained can of diced tomatoes if using. Bring to a simmer and cook, stirring occasionally, for about 10–12 minutes until the pasta absorbs liquid and starts to get tender. Keep the heat steady so the liquid reduces but doesn’t boil over. You want that sauce to thicken slowly.

Step 4:

Lower heat to medium-low and stir in 1 cup heavy cream and 1/2 cup grated Parmesan. Simmer gently for another 2–3 minutes until the sauce becomes glossy and coats the pasta. Taste and adjust salt and Cajun heat. Check chicken doneness with a thermometer — it should reach 165°F in the center. If the sauce looks too thin, let it bubble a minute longer; it will thicken as it cools.

Step 5:

Turn off the heat and stir in chopped parsley or green onions. Squeeze a little lemon over the top for brightness and finish with extra Parmesan. Serve hot, and listen for the tiny steam hisses as you twirl pasta onto a fork. Sprinkle more parsley for color and maybe an extra pinch of Cajun if you like it fiery.

Pro Tips

• For the best sear, pat chicken dry and don’t crowd the pan. Work in batches if needed so pieces brown instead of steam.
• If you like it smokier, add a dash of liquid smoke or swap smoked paprika for regular paprika.
• Use a thermometer to hit 165°F exactly — juicy chicken beats dry chicken every time.
• Leftover sauce thickens in the fridge; stir in a splash of broth or cream when reheating to revive it.

Common Mistakes to Avoid

• Skipping preheating: Classic rookie move. It changes texture and bake time.
• Overmixing: Leads to dense or chewy results. Mix until just combined.
• Guessing cook time: Always use visual cues or a timer, not just vibes.
• Overcrowding pans: Give your food some breathing room to crisp properly.

Alternatives & Substitutions

• Chicken ↔ Tofu: Use firm tofu, pressed and cubed, and pan-fry until golden. Texture will be firmer but will soak up the sauce nicely.
• Heavy cream ↔ Greek yogurt: Stir in 3/4 cup full-fat Greek yogurt off heat for a tangy, lighter creaminess (avoid boiling after adding yogurt to prevent curdling).
• Gluten-free: Use gluten-free pasta; you may need slightly less broth since some gluten-free pastas absorb less liquid.
• Dairy-free: Swap heavy cream for canned coconut milk (use light flavor coconut milk) and omit Parmesan or use a dairy-free alternative.

Variations & Tips

• Make it spicy: add chopped andouille sausage with the chicken and a pinch of cayenne for a Creole kick.
• Kid-friendly: reduce Cajun seasoning to 1 tsp and add sweet corn for playful sweetness.
• Vegetarian: skip chicken, use mushrooms and extra bell peppers, and stir in white beans for protein.
• One-skillet bake: after Step 4, top with extra cheese and broil for 2–3 minutes to get a bubbly, golden crust.
• Summer twist: add fresh cherry tomatoes and basil at the end instead of canned tomatoes for a lighter finish.
• Creative twist: finish with a spoonful of cream cheese for ultra-luxe, velvety sauce that clings like a dream.

FAQ (Frequently Asked Questions)

Can I make this ahead of time?

Yes! Cook fully, cool, and store in an airtight container in the fridge up to 3 days. Reheat gently in a skillet with a splash of broth or cream to loosen the sauce.

Can I double the recipe?

Sure thing. Use a wider pan so everything cooks evenly; you may need to increase broth by 1/2–1 cup because more pasta can absorb more liquid.

Can I substitute butter with oil?

Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil.

How do I know it’s done?

Look for a glossy, thick sauce coating the pasta, pasta cooked al dente (tender with a little bite), and chicken at 165°F internal temperature. You should see golden edges on the chicken and a fragrant, spicy steam rising when you stir.

What if I don’t have ingredient X?

No panic—use canned tomatoes instead of fresh, swap penne for rotini, or replace heavy cream with half-and-half plus a tablespoon of butter for richness. Small swaps keep dinner on track.

How I Like to Serve It

I serve this pasta right from the skillet with lemon wedges and an extra sprinkle of Parmesan. Pair it with a crisp green salad and a cold beer for weeknights, or invite friends over and add garlic bread for a casual dinner party. In winter it comforts like a warm hug; in summer I open the windows and let the spice chase the heat away.

Notes

• Store leftovers in the fridge up to 3 days. Reheat over low heat with a splash of broth to loosen the sauce.
• Safe cooking temp for chicken: 165°F.
