What Makes Fajita Chicken Mac and Cheese Special?

What makes this recipe so delicious is the combination of bold fajita seasoning and a rich, creamy cheese sauce.

The chicken is cooked with paprika, chili powder, cumin, garlic, and other savory seasonings until beautifully golden and tender. Bell peppers and onions are sautéed until slightly softened, adding sweetness and that familiar fajita flavor.

The cooked pasta is then combined with a homemade cheese sauce made with butter, milk, and melted cheese. Cheddar provides a sharp, cheesy flavor, while Monterey Jack adds extra creaminess and a smooth texture.

Instead of serving the fajita chicken separately, everything is tossed together so the pasta absorbs all those delicious flavors. The result is a comforting, cheesy dinner with a little Tex-Mex personality.

Helpful Tips for the Best Results

• Cook the pasta al dente:Slightly firm pasta holds its shape better when mixed with the creamy cheese sauce.
• Season the chicken generously:Make sure every piece is coated with fajita seasoning for maximum flavor.
• Use freshly grated cheese:It melts more smoothly than pre-shredded cheese and creates a creamier sauce.
• Don’t overcook the peppers:Cook them until slightly tender while keeping a little crunch for texture.
• Keep the heat low when adding cheese:High heat can make the sauce grainy or cause the cheese to separate.
• Adjust the spice level:Add extra chili powder or cayenne pepper for more heat, or reduce the amount for a milder family-friendly version.
• Reserve some pasta water:A small splash can help loosen the sauce if it becomes too thick.
• Serve immediately:Mac and cheese is at its creamiest when freshly prepared.

Ingredients

For the Chicken

• 1 lb (450 g) boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 tablespoon olive oil
• 1 teaspoon paprika
• 1 teaspoon chili powder
• ½ teaspoon ground cumin
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Vegetables

• 1 tablespoon unsalted butter
• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 small yellow onion, thinly sliced
• 2 cloves garlic, minced

For the Mac and Cheese

• 12 oz (340 g) elbow macaroni
• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 2 cups (480 ml) whole milk
• ½ cup (120 ml) heavy cream
• 2 cups (200 g) shredded sharp cheddar cheese
• 1 cup (100 g) shredded Monterey Jack cheese
• ½ teaspoon paprika
• ¼ teaspoon black pepper
• Salt to taste

For Garnishing

• 2 tablespoons fresh cilantro, chopped
• 2 green onions, sliced
• Extra shredded cheddar cheese
• A pinch of chili flakes (optional)

Ingredient Notes

• Chicken breasts:Boneless, skinless chicken breasts cook quickly and provide lean protein. Chicken thighs are another excellent option if you prefer a juicier texture.
• Fajita seasoning:Paprika, chili powder, cumin, garlic powder, and onion powder create the classic smoky and savory flavor.
• Bell peppers:Red and green peppers add color, sweetness, and a little crunch.
• Yellow onion:Adds natural sweetness and complements the fajita spices.
• Elbow macaroni:The classic choice for mac and cheese because its shape holds the creamy sauce beautifully. Shells or penne also work well.
• Sharp cheddar cheese:Provides a rich, bold cheese flavor.
• Monterey Jack cheese:Melts smoothly and gives the sauce extra creaminess.
• Whole milk and heavy cream:Create a rich, smooth sauce that coats the pasta.
• Fresh garlic:Adds another layer of savory flavor to the vegetables and cheese sauce.

Equipment You’ll Need

• Large pot for cooking pasta
• Large skillet or deep frying pan
• Medium saucepan
• Colander
• Cutting board
• Sharp knife
• Measuring cups and spoons
• Whisk
• Wooden spoon or spatula
• Cheese grater

Before You Begin

• Cut the chicken into evenly sized bite-sized pieces so it cooks consistently.
• Slice the bell peppers and onion into thin strips.
• Mince the garlic and grate the cheeses before cooking.
• Combine the chicken seasonings in a small bowl for easy preparation.
• Bring a large pot of salted water to a boil for the macaroni.
• Measure the milk, cream, butter, and flour before preparing the cheese sauce.

Helpful note:For the creamiest mac and cheese, grate the cheddar and Monterey Jack directly from a block. Freshly grated cheese melts more smoothly and helps prevent a grainy sauce.

How to Make Fajita Chicken Mac and Cheese

Preparation Time

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 4–6

Step-by-Step Instructions

Cook the Macaroni

Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to the package instructions until al dente.

Drain the pasta and set it aside. Reserve about ½ cup of pasta water in case you need to thin the cheese sauce later.

Season the Chicken

In a small bowl, combine the paprika, chili powder, cumin, garlic powder, onion powder, salt, and black pepper.

Place the chicken pieces in a large bowl and sprinkle the seasoning mixture over them. Toss until every piece is evenly coated.

Cook the Chicken

Heat the olive oil in a large skillet over medium-high heat.

Add the seasoned chicken in a single layer and cook for approximately 6–8 minutes, turning occasionally, until golden brown and cooked through. The internal temperature should reach 165°F (74°C).

Transfer the chicken to a plate and set aside.

Sauté the Vegetables

In the same skillet, melt 1 tablespoon of butter over medium heat.

Add the sliced red bell pepper, green bell pepper, and onion. Cook for about 4–5 minutes, stirring occasionally, until the vegetables are slightly tender but still have a little crunch.

Add the minced garlic and cook for another 30 seconds until fragrant.

Remove the vegetables from the skillet and set aside with the chicken.

Prepare the Creamy Cheese Sauce

In a medium saucepan, melt 2 tablespoons of butter over medium heat.

Add the flour and whisk continuously for about 1 minute to create a smooth roux.

Gradually pour in the milk and heavy cream, whisking constantly to prevent lumps.

Cook for 3–5 minutes, stirring frequently, until the sauce begins to thicken.

Reduce the heat to low. Add the paprika and black pepper, then gradually stir in the shredded cheddar and Monterey Jack cheese.

Continue stirring until the cheese melts completely and the sauce becomes smooth and creamy. Taste and add salt if needed.

Combine Everything

Add the cooked macaroni to the cheese sauce and stir gently until the pasta is evenly coated.

Fold in the cooked chicken, sautéed bell peppers, and onions.

Mix everything together until the ingredients are well distributed and heated through.

If the sauce feels too thick, add a small splash of reserved pasta water or warm milk until it reaches your preferred consistency.

Garnish and Serve

Remove the skillet from the heat and sprinkle with chopped fresh cilantro, sliced green onions, and extra shredded cheddar cheese.

Add a pinch of chili flakes if you enjoy a little extra heat.

Serve immediately while the cheese sauce is warm, creamy, and delicious!

Helpful Tips for Perfect Fajita Chicken Mac and Cheese

• Cook the pasta al dente:This prevents it from becoming too soft when mixed with the cheese sauce.
• Cut chicken evenly:Similar-sized pieces cook more consistently and stay tender.
• Don’t overcrowd the skillet:Cook the chicken in batches if necessary to help it brown properly.
• Keep the cheese sauce on low heat:Adding cheese over high heat can make the sauce grainy.
• Grate cheese fresh:Freshly grated cheese melts more smoothly than pre-shredded varieties.
• Keep the peppers slightly crisp:This adds texture and keeps the vegetables from becoming mushy.
• Adjust the consistency:Add warm milk or reserved pasta water if the sauce thickens too much.
