Ingredients Breakdown

• Chicken: 1.25–1.5 lb boneless, skinless chicken breasts (or thighs for extra juiciness), sliced into thin strips.
• Pasta: 12 oz penne, rigatoni, or fettuccine (short shapes grab sauce better IMO).
• Cajun seasoning: 2–3 tbsp (store-bought or homemade). Look for a blend with paprika, garlic, onion, thyme, oregano, cayenne.
• Salt & pepper: To season chicken and sauce to taste.
• Olive oil + butter: 1 tbsp oil + 2 tbsp butter for searing and richness.
• Garlic: 4 cloves, minced. Non-negotiable.
• Onion: 1 small yellow onion, finely chopped.
• Bell pepper: 1 red bell pepper, thinly sliced, for color and sweetness.
• Chicken broth: 1 cup, low sodium for better control.
• Heavy cream: 1.25 cups for that silky, restaurant-level body.
• Parmesan: 3/4 cup, freshly grated so it melts properly (no pre-shredded sawdust, please).
• Tomato paste: 1 tbsp for umami and color.
• Lemon juice: 1–2 tsp to brighten the finish.
• Fresh parsley or green onions: For garnish and freshness.
• Optional heat boosters: Pinch of cayenne or red pepper flakes if you’re feeling spicy.

The Method – Instructions

1. Boil the pasta: Salt a large pot of water like the ocean.

   Cook pasta 1 minute shy of package directions. Reserve 3/4 cup pasta water, then drain.

2. Season the chicken: Pat dry. Toss with 1.5–2 tbsp Cajun seasoning, a big pinch of salt, and black pepper.
3. Sear like you mean it: Heat olive oil and 1 tbsp butter in a large skillet over medium-high.

   Sear chicken in a single layer 3–4 minutes per side until browned and just cooked. Remove to a plate.

4. Sweat the aromatics: Lower to medium. Add remaining 1 tbsp butter, onion, and bell pepper.

   Cook 3–4 minutes until softened. Stir in garlic for 30 seconds until fragrant.

5. Build the base: Stir in tomato paste for 1 minute to caramelize slightly. Sprinkle in remaining 0.5–1 tbsp Cajun seasoning.
6. Deglaze: Pour in chicken broth, scraping up browned bits.

   Simmer 2 minutes to reduce slightly.

7. Creamy time: Reduce heat to medium-low. Add heavy cream and bring to a gentle simmer. Do not boil.
8. Cheese it up: Stir in Parmesan by handfuls until melted and smooth.

   If too thick, splash in pasta water. If too thin, simmer a minute.

9. Toss it all: Add cooked pasta and chicken (with juices). Toss to coat.

   Adjust seasoning with salt, pepper, and more Cajun spice if needed. Finish with lemon juice for brightness.

10. Garnish and serve: Top with parsley or green onions. Optional: extra Parmesan and a pinch of red pepper flakes.

    Serve immediately while it’s glossy and elite.

How to Store

• Fridge: Store in an airtight container up to 4 days. Add a splash of milk or broth when reheating to revive the sauce.
• Freezer: 1–2 months, but cream sauces can separate. If freezing, undercook pasta slightly and reheat gently on the stove with extra cream.
• Reheat: Low heat on stovetop, stirring with a splash of liquid.

  Microwave in short bursts, stirring between intervals.

Health Benefits

• High-quality protein: Chicken delivers lean protein to support muscle recovery and satiety.
• Capsaicin kick: Cajun spices (cayenne, paprika) may support metabolism and reduce inflammation.
• Balanced carbs: Pasta provides steady energy; choose whole-wheat or chickpea pasta for extra fiber and micronutrients.
• Healthy fats: Olive oil and dairy fat increase nutrient absorption and keep you full longer.
• Veg boost: Bell peppers and onions add vitamin C, antioxidants, and a little crunch so your conscience can chill.

Avoid These Mistakes

• Overcooking chicken: Thin strips cook fast. Pull them as soon as they’re done to keep them juicy.
• Boiling the cream: High heat can cause splitting. Keep it at a gentle simmer for a silky sauce.
• Using pre-shredded cheese: Anti-caking agents = grainy sauce.

  Freshly grate for smooth melt.

• Skipping pasta water: It’s liquid gold. The starch helps the sauce cling and emulsify.
• Under-seasoning: Taste and adjust. Different Cajun blends vary; salt balances the heat and cream.

Alternatives

• Protein swaps: Shrimp (cook 1–2 minutes per side), andouille sausage, or a combo for surf-and-turf energy.
• Dairy tweaks: Half-and-half works; reduce broth slightly.

  For lighter options, use evaporated milk. For a luxe finish, add 2 oz cream cheese.

• Spice levels: Mild: use 1.5 tbsp Cajun seasoning, no extra cayenne. Hot: add 1/4 tsp cayenne or a splash of hot sauce.
• Veg upgrades: Mushrooms, spinach, sun-dried tomatoes, or roasted cherry tomatoes for extra depth.
• Gluten-free: Use GF pasta and verify seasoning is GF.

  Sauce is naturally gluten-free.

• Lower carb: Swap pasta for zucchini noodles or spaghetti squash; simmer sauce a bit longer to thicken.

FAQ

Can I make this ahead?

Yes. Cook everything, cool, and refrigerate. Reheat gently with a splash of milk or broth to restore the sauce.

For best texture, cook pasta fresh and reheat the sauce and chicken.

What’s the best Cajun seasoning?

Look for blends with paprika, garlic, onion, thyme, oregano, black pepper, and cayenne. Avoid ones loaded with salt so you control the seasoning. Tony Chachere’s, Slap Ya Mama, or homemade are solid options.

Why did my sauce split?

Likely too much heat or pre-shredded cheese.

Keep the sauce at a gentle simmer, add cheese off heat or on low, and stir slowly. If it breaks, whisk in a few tablespoons of cold cream or a knob of cream cheese to bring it back.

Can I use milk instead of cream?

You can, but expect a thinner, less velvety sauce. Use whole milk and add 2–3 tsp flour to the onion/pepper step to help thicken, or finish with a little cream cheese for body.

How can I make it extra smoky?

Use smoked paprika in your Cajun blend, sear the chicken well, and add a splash of smoked sausage fat or a few drops of liquid smoke (very little—go easy).

Is this spicy?

It’s as spicy as you make it.

Start with less Cajun seasoning and add more to taste. You can always increase heat with cayenne or hot sauce at the end—easier than going the other way, FYI.
