What You’ll Need

• Chicken: 2 large boneless skinless chicken breasts (about 1.25–1.5 pounds), butterflied or pounded to even thickness
• Pasta: 12 ounces penne or fettuccine
• Cajun seasoning: 1.5 tablespoons (store-bought or homemade)
• Salt and pepper: To taste
• Olive oil: 2 tablespoons
• Butter: 2 tablespoons
• Garlic: 3 cloves, minced
• Red bell pepper: 1 small, thinly sliced
• Onion: 1/2 medium yellow onion, thinly sliced
• Heavy cream: 1.5 cups
• Chicken broth: 1/2 cup (low-sodium preferred)
• Parmesan cheese: 3/4 cup, freshly grated
• Cayenne pepper: 1/8–1/4 teaspoon, optional for extra heat
• Fresh parsley: 2 tablespoons, chopped (for garnish)
• Lemon: 1/2, for a squeeze at the end (optional but brightens the sauce)

Instructions

1. Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package directions. Reserve 1/2 cup pasta water, then drain.
2. Season the chicken: Pat the chicken dry. Sprinkle all over with Cajun seasoning, salt, and pepper. Press gently so the seasoning adheres.
3. Sear the chicken: Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high. Add chicken and cook 4–6 minutes per side, until browned and cooked through (165°F). Transfer to a plate and tent with foil to rest.
4. Sauté the aromatics: Reduce heat to medium. Add the remaining olive oil and butter.Stir in garlic, onion, and bell pepper. Cook 3–4 minutes until softened and fragrant, scraping up browned bits.
5. Build the sauce: Pour in chicken broth and simmer 1–2 minutes to reduce slightly. Stir in heavy cream and a pinch of cayenne if using.Simmer gently 3–4 minutes, stirring, until the sauce starts to thicken.
6. Add the cheese: Lower the heat and stir in Parmesan until melted and smooth. Taste and adjust salt and pepper. If the sauce gets too thick, splash in reserved pasta water.
7. Slice the chicken: Slice the rested chicken into strips or bite-size pieces.
8. Toss it together: Add the drained pasta and chicken to the skillet. Toss to coat, adding a bit of pasta water as needed to loosen the sauce. Finish with a light squeeze of lemon if desired.
9. Garnish and serve: Top with chopped parsley and extra Parmesan. Serve hot while the sauce is silky.

Keeping It Fresh

• Storage: Keep leftovers in an airtight container in the fridge for up to 3 days.
• Reheating: Warm gently on the stovetop over low heat with a splash of milk or broth to restore creaminess. Avoid high heat to prevent the sauce from separating.
• Freezing: Cream sauces don’t freeze well. If you must freeze, store the chicken and sauce separately and expect a slight texture change.
• Make-ahead tip: Cook the chicken in advance and refrigerate. Make the sauce and pasta fresh for best texture.

Health Benefits

• Protein-rich: Chicken breast delivers lean protein to keep you satisfied and support muscle health.
• Balanced carbs: Pasta fuels energy needs, especially if you choose whole-wheat or high-protein pasta.
• Micronutrients: Bell peppers and onions contribute vitamin C, antioxidants, and fiber.
• Customizable fats: You can lighten the sauce by using half-and-half or evaporated milk, though the texture will be less silky.

What Not to Do

• Don’t overcook the chicken: Dry chicken ruins the dish. Pull it at 165°F and let it rest before slicing.
• Don’t boil the cream hard: A gentle simmer keeps the sauce smooth. A rolling boil can cause separation.
• Don’t skip the pasta water: The starchy liquid helps the sauce cling and adjust thickness without breaking.
• Don’t use pre-shredded Parmesan: It often contains anti-caking agents that hinder melting. Freshly grated is best.
• Don’t add all the salt at once: Cajun seasoning and Parmesan are salty.Season gradually and taste.

Recipe Variations

• Blackened chicken: Use a cast-iron skillet and cook the chicken over higher heat for a deeper crust and smokier flavor.
• Sausage swap: Replace or supplement the chicken with sliced and seared andouille or smoked sausage.
• Veggie boost: Add mushrooms, spinach, or cherry tomatoes in the sauté step for color and nutrients.
• Lighter sauce: Use 1 cup half-and-half and 1/2 cup cream. Simmer gently and add a teaspoon of cornstarch slurry if you want more body.
• Extra heat: Add sliced jalapeño with the peppers, or finish with hot sauce.
• Gluten-free: Use gluten-free pasta and check your Cajun seasoning for hidden gluten.
• Dairy-free: Swap in a rich, unsweetened coconut cream and a dairy-free Parmesan-style cheese. Flavor will differ but still be tasty.

FAQ

Can I use pre-cooked chicken?

Yes.

Slice it and warm it in the sauce just before adding the pasta. Season the sauce a little more to make up for the chicken not being seared in the pan.

How spicy is this recipe?

It’s medium by default. For mild, use a mild Cajun blend and skip the cayenne.

For hot, add extra cayenne or a few dashes of hot sauce.

What can I use instead of heavy cream?

Half-and-half works with a gentler simmer, or use evaporated milk for a lighter option. If needed, thicken slightly with a cornstarch slurry to reach a creamy consistency.

Which pasta shape is best?

Penne and fettuccine are classics. Short, ridged shapes like rigatoni also hold the sauce well.

Why did my sauce break?

High heat or prolonged boiling can cause separation.

Keep the heat moderate, add cheese off the boil, and use a splash of pasta water to emulsify if needed.

Can I make it without bell peppers?

Absolutely. The peppers add sweetness and texture, but the dish is still great without them. Consider adding mushrooms or spinach for balance.

How do I make homemade Cajun seasoning?

Mix 2 teaspoons paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon dried oregano, 1 teaspoon dried thyme, 1/2 teaspoon black pepper, 1/2 teaspoon salt, and a pinch of cayenne.

Adjust salt to taste.
