👨‍🍳 Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil and cook spaghetti according to package instructions. Drain and set aside.

2. Cook the Chicken

Season the chicken with Cajun seasoning, paprika, salt, and pepper.
Heat olive oil in a skillet over medium-high heat and cook chicken until golden and fully cooked (about 6–8 minutes). Set aside.

3. Make the Sauce

In the same pan, melt butter over medium heat. Add garlic and sauté for 1 minute until fragrant.
Stir in flour and cook for 1–2 minutes to form a roux.

4. Add Liquids & Cheese

Slowly whisk in milk until smooth. Let simmer until slightly thickened.
Add mozzarella, Parmesan, Cajun seasoning, and red pepper flakes. Stir until melted and creamy.

5. Combine Everything

Add cooked spaghetti and chicken back into the pan. Toss until everything is well coated in the creamy sauce.

6. Serve

Serve hot, topped with extra Parmesan and fresh herbs if desired.
