Make Spicy Cajun Chicken Mac and Cheese: A Simple Method

Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente. Drain and set aside.
Step 2: Sauté the Chicken
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the diced chicken breast and sprinkle with 2 teaspoons of Cajun seasoning, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Cook, stirring occasionally, until the chicken is cooked through and lightly browned, about 6-8 minutes. Remove from heat and set aside.
Step 3: Prepare the Cheese Sauce
In a medium saucepan, heat 2 cups of milk over medium heat until warm but not boiling. In a separate small bowl, whisk together 1/4 cup of all-purpose flour with a little cold milk to create a smooth slurry. Slowly whisk this into the warm milk, stirring constantly until the mixture thickens, about 3-5 minutes.
Step 4: Add the Cheeses
Reduce the heat to low and gradually stir in 2 cups shredded cheddar cheese and 1 cup shredded Monterey Jack cheese until melted and smooth. Make sure the sauce is creamy and well combined.
Step 5: Combine Pasta, Chicken, and Sauce
Add the cooked macaroni and seasoned chicken to the cheese sauce. Stir gently to combine everything evenly, making sure each piece of pasta is coated with that luscious cheese.
Step 6: Add Topping and Bake (Optional)
If you love a crunchy topping, transfer the mac and cheese mixture to a baking dish. Sprinkle 1/2 cup breadcrumbs evenly over the top. Bake in a preheated oven at 350°F (175°C) for about 15 minutes or until the top is golden and crispy.
Step 7: Garnish and Serve
Remove from oven and sprinkle 1/4 cup chopped green onions over the top for a fresh pop of flavor. Serve hot and enjoy the spicy, cheesy goodness.

In-Season Flavor Ideas

- Add roasted red bell peppers or fresh corn kernels for a sweet contrast.
- Swap green onions with chives or fresh parsley for a different herbal note.
- Incorporate diced tomatoes for a touch of acidity that balances the richness.
- Mix in sautéed mushrooms or spinach for extra veggie goodness.
- Top with crispy fried onions instead of breadcrumbs for more crunch.
Frequent Missteps to Avoid
- Overcooking the pasta: This can make your mac and cheese mushy. Aim for al dente for the best texture.
- Not seasoning the chicken properly: The Cajun seasoning is essential for flavor. Don’t skimp on it.
- Adding cheese too quickly: Adding cheese to boiling milk can cause it to clump. Melt cheese over low heat and stir gently.
- Skipping the flour slurry: This step thickens your sauce perfectly. Without it, your cheese sauce might be runny.
- Neglecting the garnish: Green onions add freshness and color that brighten the entire dish.
Keep-It-Fresh Plan
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk to loosen the sauce and warm gently on the stovetop or microwave to avoid drying out the pasta. You can also freeze the mac and cheese without breadcrumbs for up to 2 months; thaw overnight in the fridge before reheating. Breadcrumb toppings are best added fresh after reheating for maximum crunch.
Spicy Cajun Chicken Mac and Cheese FAQs
Can I use a different type of pasta?
Absolutely! While elbow macaroni is traditional, you can swap in penne, rotini, or shells. Just adjust the cooking time according to the pasta shape you choose.
How spicy is this recipe?
The heat level depends on the Cajun seasoning you use. Most blends have a moderate spice level, but if you want it milder, reduce the amount or choose a seasoning blend with less cayenne pepper.

Yes! Simply omit the chicken and consider adding sautéed vegetables like bell peppers, mushrooms, or even spicy smoked tofu to keep the dish hearty and flavorful.
