4. Equipment Needed

5. Step-by-Step Instructions

Step 1: Cook the Pasta

• Boil a large pot of salted water.

• Add penne and cook for 10-11 minutes, until al dente.

• Reserve ½ cup of pasta water, then drain and set aside with 1 tbsp olive oil.

Pro Tip: Salting pasta water adds flavor from the start it should taste like the sea.

Step 2: Prepare the Chicken

• Pat dry chicken strips with paper towels.

• Combine Cajun seasoning, paprika, garlic powder, onion powder, salt, and pepper in a bowl.

• Coat chicken evenly in the spice mix.

Pro Tip: Patting the chicken dry helps it sear beautifully without steaming.

Step 3: Sear the Chicken

• Heat 1 tbsp olive oil in a skillet over medium-high heat (190°C / 375°F).

• Cook chicken 3-4 minutes per side until golden brown and cooked through.

• Transfer to a plate and cover to keep warm.

Visual cue: The chicken should have a deep golden crust and juicy center.

Step 4: Start the Garlic Butter Base

• In the same skillet, add 2 tbsp butter.

• Sauté minced garlic for 30 seconds, until fragrant and golden.

Pro Tip: Don’t burn garlic — lower the heat if it starts to brown too quickly.

Step 5: Make the Roux

• Sprinkle in 2 tbsp flour and whisk constantly for 1 minute.

• The mixture should be golden and smell nutty — this is your base for a silky sauce.

Step 6: Add Milk & Cream

• Gradually pour in milk while whisking to avoid lumps.

• Add cream next, stirring continuously until smooth.

• Simmer on low heat (165°C / 330°F) for 3-4 minutes until slightly thickened.

Visual cue: The sauce should coat the back of a spoon without dripping.

Step 7: Season the Sauce

• Stir in Parmesan, Italian seasoning, chili flakes (if using), salt, and black pepper.

• Taste and adjust for spice and salt balance.

Chef’s Tip: Use freshly grated Parmesan — pre-shredded cheese doesn’t melt as smoothly.

Step 8: Combine Chicken & Pasta

• Return chicken to the skillet along with any juices.

• Add drained pasta and toss to coat everything evenly in the sauce.

• Add a splash of reserved pasta water if the sauce feels too thick.

Visual cue: Pasta should appear glossy and creamy, not clumpy or dry.

Step 9: Add Final Touches

• Fold in spinach, mushrooms, or lemon zest if desired.

• Top with extra Parmesan and parsley.

Step 10: Serve & Enjoy

• Plate in warm bowls.

• Drizzle with melted butter or olive oil.

• Garnish with fresh herbs and chili flakes for a vibrant finish.

Pro Tip: Serve immediately for the creamiest texture — sauce thickens as it cools.

6. Pro Tips & Chef Secrets

• Layer your flavors: Season each stage pasta water, chicken, and sauce for depth.

• Don’t overcook cream: Keep heat low to prevent curdling.

• Use pasta water wisely: It emulsifies and gives the sauce its silky body.

• Want it spicier? Add extra cayenne or a dash of hot sauce.

• Dairy-Free Version: Use coconut milk and olive oil instead of cream and butter.

• Vegetarian Twist: Replace chicken with grilled mushrooms or roasted cauliflower.

• Shrimp Variation: Use 450 g shrimp and cook for only 2 minutes per side.

Mistakes to Avoid

• Adding cream at high heat (causes curdling).

• Over-seasoning with salt (Parmesan already adds saltiness).

• Using pre-grated cheese (clumps and dull flavor).

• Forgetting pasta water (results in dry sauce).

• Overcooking chicken (leads to dryness).

Notes

• Pasta Water Magic: Reserve at least ½ cup of pasta water. The starch helps your sauce cling beautifully to the pasta and prevents it from drying out.
• Butter is Flavor: Use real butter, not margarine it makes the garlic base richer and silkier.
• Juicy Chicken Secret: Pat chicken dry before seasoning; it helps form that flavorful golden crust.
• Spice Control: For a mild version, reduce Cajun and cayenne by half. For heat lovers, add extra chili flakes or a dash of hot sauce.
• Vegetarian Version: Replace chicken with grilled mushrooms, roasted cauliflower, or tofu.
• Dairy-Free Option: Substitute cream with full-fat coconut milk and use olive oil instead of butter.
• Garlic Perfection: Add garlic only after butter melts it burns quickly and turns bitter if added too soon.
• Bright Finish: A squeeze of lemon before serving balances the richness and enhances the Cajun spices.
• Cheese Tip: Always add Parmesan off the heat for a creamy melt instead of clumping.
• Reheating Tip: Reheat slowly with milk or cream, stirring constantly avoid microwaving at full power.
• Meal-Prep Friendly: Make the sauce and chicken ahead, then toss with freshly cooked pasta before serving for best texture.
