Ingredients Method

Ingredients

  

• 12 oz (340 g) pasta – penne, fettuccine, or rigatoni
• 1 lb (450 g) boneless, skinless chicken breasts, thinly sliced
• 2–3 tbsp Cajun seasoning (store-bought or homemade), divided
• 2 tbsp olive oil
• 1 tbsp unsalted butter
• 1 red bell pepper, thinly sliced
• 1 yellow bell pepper, thinly sliced
• 1 small red onion, thinly sliced (or 1 shallot, minced)
• 3–4 cloves garlic, minced
• 1 cup (240 ml) low-sodium chicken broth
• 1 cup (240 ml) heavy cream (or half-and-half for lighter)
• 1/2 cup (50 g) grated Parmesan, plus more for serving
• 1 tsp smoked paprika (optional, for extra depth)
• 1/4 tsp cayenne (optional, for extra heat)
• Salt and black pepper, to taste
• Juice of 1/2 lemon (about 1 tbsp)
• 2 tbsp chopped parsley or scallions, for garnish

Method

 

1. Boil the pasta. Bring a large pot of salted water to a boil. Cook the pasta until just shy of al dente. Reserve 1/2 cup of pasta water, then drain and set aside.
2. Season the chicken. Pat the chicken dry. Toss with 1–1.5 tbsp Cajun seasoning, a pinch of salt, and black pepper. Coat evenly so every piece gets flavor.
3. Brown the chicken. Heat olive oil in a large skillet over medium-high. Add the chicken in a single layer and cook 3–4 minutes per side until browned and cooked through. Transfer to a plate and tent loosely with foil.
4. Sauté the veggies. Reduce heat to medium. Add butter, then the peppers and onion with a pinch of salt. Cook 4–5 minutes until softened and lightly charred at the edges. Stir in garlic and cook 30 seconds until fragrant.
5. Deglaze and season. Pour in the chicken broth. Scrape up the browned bits. Stir in remaining Cajun seasoning, smoked paprika, and cayenne if using. Simmer 2 minutes to reduce slightly.
6. Make it creamy. Lower the heat. Add the cream and bring to a gentle simmer, not a boil. Stir in Parmesan until melted and smooth. Taste and adjust salt and pepper.
7. Combine pasta and chicken. Add the cooked pasta and chicken to the skillet. Toss to coat. If the sauce is thick, splash in reserved pasta water a little at a time until silky and clinging to the noodles.
8. Brighten and serve. Stir in lemon juice for a clean finish. Garnish with parsley or scallions and extra Parmesan. Serve hot.

Why This Recipe Works

Save

This dish balances bold Cajun spices with a velvety cream sauce, so you get flavor in every bite without burning your taste buds. Browning the chicken first creates flavorful fond, which melts into the sauce and deepens the taste. A mix of bell peppers and garlic adds natural sweetness and aroma to keep the heat in check.

Finally, finishing the pasta in the sauce helps it absorb the seasoning, giving the whole bowl a restaurant-level finish.

Ingredients

• 12 oz (340 g) pasta – penne, fettuccine, or rigatoni
• 1 lb (450 g) boneless, skinless chicken breasts, thinly sliced
• 2–3 tbsp Cajun seasoning (store-bought or homemade), divided

   Transfer to a plate and tent loosely with foil.

4. Sauté the veggies. Reduce heat to medium. Add butter, then the peppers and onion with a pinch of salt. Cook 4–5 minutes until softened and lightly charred at the edges.

   Stir in garlic and cook 30 seconds until fragrant.

8. Brighten and serve. Stir in lemon juice for a clean finish.

   Garnish with parsley or scallions and extra Parmesan. Serve hot.

Keeping It Fresh

Store leftovers in an airtight container in the fridge for up to 3 days. The sauce will thicken as it chills, so add a splash of milk, cream, or water when reheating.

Warm gently over low heat on the stove, stirring often, to keep the sauce from splitting. If microwaving, heat in short bursts and stir between intervals. For best texture, avoid freezing; cream sauces can become grainy after thawing.

Benefits of This Recipe

• Weeknight-friendly: Ready in about 30 minutes with simple steps and one main pan.
• Balanced flavor: Cream tempers the spice, while peppers add sweetness and lemon adds brightness.
• Customizable heat: Choose mild Cajun seasoning or add cayenne for a bigger kick.
• Protein-packed: Chicken keeps it satisfying without feeling heavy.
• Great for leftovers: Reheats well with a splash of liquid to revive the sauce.

Pitfalls to Watch Out For

• Overcooking the chicken: Thin slices cook fast.

  Pull them once just cooked; they’ll warm again in the sauce.

• Boiling the cream: A hard boil can cause splitting. Keep the heat low and simmer gently.
• Under-seasoning: Taste the sauce before adding pasta. Cajun blends vary in salt; adjust as needed.
• Soggy pasta: Cook to just shy of al dente and finish in the sauce so it absorbs flavor but stays firm.
• Dry sauce: Use reserved pasta water to loosen and emulsify for a glossy, clingy finish.

Recipe Variations

• Andouille twist: Swap half the chicken for sliced andouille sausage for a smoky, savory punch.
• Shrimp option: Use peeled shrimp instead of chicken.

  Sear 1–2 minutes per side, remove, and add back at the end.

• Lighter version: Use half-and-half and reduce Parmesan slightly. Thicken with a few tablespoons of reserved pasta water.
• Veggie-loaded: Add mushrooms, spinach, or zucchini with the peppers for extra color and texture.
• Dairy-free: Use coconut milk or a barista-style oat cream and skip Parmesan. Add nutritional yeast for a cheesy note.
• Gluten-free: Use your favorite gluten-free pasta and check your Cajun seasoning for hidden gluten.
• Extra smoky: Add a splash of smoked paprika and a few drops of liquid smoke, used sparingly.

FAQ

How spicy is Cajun seasoning?

It varies by brand.

Some blends lean smoky and mild, others pack real heat. Start with less, taste the sauce, and add more—or a pinch of cayenne—if you want extra kick.

Can I make this ahead?

You can cook the chicken and chop the veggies a day in advance. For the best texture, make the sauce and combine with pasta right before serving.

Reheat gently with a splash of liquid.

What pasta shape works best?

Short, ridged shapes like penne or rigatoni hold on to the creamy sauce, but fettuccine is great for a silky, slurpable bowl. Use what you have and cook to just shy of al dente.

Can I use milk instead of cream?

You can, but the sauce will be thinner and more likely to split. If using milk, add a tablespoon of cream cheese or a knob of butter to stabilize, and keep the heat low.

What if my sauce is too thick or too thin?

If too thick, whisk in small amounts of warm pasta water or broth until silky.

If too thin, simmer gently for a few minutes to reduce, or add more Parmesan to help it thicken.

How do I make homemade Cajun seasoning?

Combine 2 tsp paprika, 1 tsp each garlic powder, onion powder, dried oregano, dried thyme, and black pepper, plus 1/2–1 tsp cayenne and 1–2 tsp kosher salt. Adjust cayenne to taste.

Why add lemon juice?

A touch of acid brightens the creamy sauce and balances the richness. It also lifts the flavors of the spices and peppers, making the whole dish taste fresher.
