Step-by-Step Instructions: Spicy Cajun Chicken Rigatoni with Creamy Mozzarella Alfredo

Ingredients Overview

• Rigatoni pasta

• Chicken breasts or thighs (boneless, skinless)

• Cajun seasoning blend (smoked paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, pepper)

• Butter and olive oil

• Garlic and onion

• Heavy cream

• Whole milk or half-and-half

• Mozzarella cheese (fresh or shredded)

• Parmesan cheese (for added depth)

• Fresh parsley (for garnish)

• Salt and black pepper

Step 1: Prepare the Cajun Chicken

1. Slice the chicken into bite-sized strips or cubes, approximately 1-inch pieces for even cooking and easy tossing with pasta.

2. Season the chicken generously with your Cajun spice blend. Be sure to coat all sides evenly for full flavor impact.

3. Heat a large skillet over medium-high heat and add a mix of butter and olive oil (about 1 tablespoon each). The butter adds richness while the oil prevents burning.

4. Once the fat is hot and shimmering, add the chicken pieces in a single layer. Avoid overcrowding the pan to ensure proper searing.

5. Cook the chicken undisturbed for 3–4 minutes until the underside is nicely browned. Flip and cook for another 3 minutes until the chicken is cooked through and has a golden crust.

6. Remove the chicken from the skillet and set aside on a plate. Keep warm.

Step 2: Cook the Rigatoni Pasta

1. Bring a large pot of salted water to a rolling boil (about 4 quarts of water per pound of pasta; salt should be like seawater).

2. Add the rigatoni and cook according to package instructions until al dente (firm to the bite, usually 10–12 minutes).

3. Reserve 1 cup of pasta cooking water, then drain the pasta.

4. Toss the drained rigatoni with a drizzle of olive oil to prevent sticking and set aside.

Step 3: Make the Creamy Mozzarella Alfredo Sauce

1. In the same skillet used for the chicken, reduce heat to medium and add 2 tablespoons of butter.

2. Add minced garlic (about 3 cloves) and finely chopped onion (½ medium onion). Sauté until fragrant and translucent, about 2–3 minutes.

3. Pour in 1 cup heavy cream and ½ cup whole milk or half-and-half. Stir gently and bring to a low simmer.

4. Reduce heat to low and slowly add 2 cups shredded mozzarella cheese, stirring continuously until fully melted and smooth.

5. For added depth and a slightly nutty flavor, stir in ½ cup grated Parmesan cheese.

6. If the sauce is too thick, add reserved pasta water a little at a time to reach your desired consistency.

7. Season with salt and freshly ground black pepper to taste.

Step 4: Combine Pasta, Chicken, and Sauce

1. Add the cooked rigatoni directly into the skillet with the Alfredo sauce.

2. Toss gently to coat the pasta evenly.

3. Return the cooked Cajun chicken to the skillet.

4. Stir to combine all ingredients, allowing the chicken to reheat and the flavors to meld.

Step 5: Final Touches and Serving

1. Taste and adjust seasoning as needed — more salt, pepper, or even a pinch of cayenne for extra heat.

2. Garnish with freshly chopped parsley for a pop of color and fresh herbal brightness.

3. Serve immediately with extra grated Parmesan on the side.

Tips for Perfection

• Chicken doneness: Use an instant-read thermometer to ensure the chicken reaches 165°F (74°C) without overcooking.

• Cheese selection: Fresh mozzarella melts creamier but shredded low-moisture mozzarella works well too.

• Sauce consistency: Reserve pasta water is your secret weapon to adjust thickness without diluting flavor.

• Balancing spice: Adjust Cajun seasoning heat level based on your preference; add cayenne sparingly.
