Ingredients You’ll Need

For the Pasta & Protein:

  • Penne Pasta: 12 oz—its shape is perfect for holding the creamy sauce.
  • Protein: 1 lb boneless, skinless chicken breasts (thinly sliced) or large shrimp (peeled & deveined).
  • Olive Oil & Butter: 1 tbsp each—for searing and building flavor.
  • Bell Peppers: 1 red and 1 green, thinly sliced for sweetness and crunch.
  • Garlic: 3 cloves, minced.

For the Signature Sauce:

  • Heavy Cream: 1 ½ cups – creates the luscious, velvety base.
  • Parmesan Cheese: ½ cup, freshly grated—for salty, umami depth.
  • Cajun Seasoning: 2 tsp – the essential spice blend.
  • Smoked Paprika: ½ tsp – adds warm, smoky notes.
  • Red Pepper Flakes: ½ tsp (or to taste) – controls the spicy “bite.”
  • Salt & Black Pepper: To taste.

For Garnish (Optional):

  • Fresh parsley or cilantro, chopped.
  • A squeeze of fresh lime juice.

How to Make It: Step-by-Step

  1. Cook the Pasta: Boil penne in well-salted water until al dente (about 1 minute less than package directions). Reserve ½ cup of the starchy pasta water, then drain.
  2. Sear the Protein: Season chicken or shrimp with salt, pepper, and 1 tsp Cajun seasoning. Heat olive oil in a large skillet over medium-high. Cook until golden and cooked through (4-5 mins per side for chicken, 2-3 mins per side for shrimp). Remove and set aside.
  3. Sauté the Veggies: In the same skillet, melt butter with a drizzle of oil. Add sliced peppers and minced garlic. Sauté for 3-4 minutes until softened and fragrant.
  4. Build the Sauce: Reduce heat to medium. Sprinkle in remaining Cajun seasoning, smoked paprika, and red pepper flakes. Stir for 30 seconds to toast the spices. Pour in the heavy cream, bring to a gentle simmer (do not boil).
  5. Finish the Sauce: Stir in grated Parmesan until melted and the sauce is smooth.
  6. Combine Everything: Add the drained pasta and cooked protein back to the skillet. Toss everything to coat in the sauce, adding reserved pasta water a little at a time if needed to loosen it.
  7. Serve: Garnish with fresh herbs and a squeeze of lime if desired. Serve immediately.

Pro Tips for Success

  • Don’t Overcook the Pasta: It will continue to cook in the hot sauce. Al dente is key.
  • Reserve Pasta Water: This starchy liquid is your secret weapon for creating a silky, clingy sauce.
  • Season in Layers: Season your protein and your sauce separately for the deepest flavor.
  • Control the Heat: Start with fewer red pepper flakes; you can always add more. For a milder dish, use a mild Cajun seasoning.

What to Serve With It

  • Garlic Bread: Essential for scooping up every last bit of sauce.
  • A Crisp Salad: A simple green salad with a light vinaigrette balances the richness.
  • Grilled Vegetables: Asparagus or zucchini make a healthy, colorful side.
  • A Cooling Drink: Iced tea, lemonade, or a crisp lager.

Storing & Reheating

  • Fridge: Store in an airtight container for up to 3-4 days.
  • Reheat: Gently warm in a skillet over low heat with a splash of milk or cream to restore the sauce’s consistency. The microwave can cause separation.

Frequently Asked Questions

  • Can I make it vegetarian? Absolutely! Use mushrooms, chickpeas, or extra veggies in place of the meat.
  • What if my sauce is too thick? Thin it with a splash of reserved pasta water, broth, or cream.
  • Can I use a different pasta? Yes! Rigatoni, fettuccine, or bowties all work well.
  • Is it very spicy? The heat is customizable. Adjust the Cajun seasoning and red pepper flakes to your taste.
