The Method for Cheesy Baked Chicken Fajita Mac

Step 1: Cook the Macaroni

Fill a large pot with water, add a pinch of salt, and bring it to a boil. Add the 8 oz elbow macaroni and cook according to package instructions until al dente. Drain the pasta and set it aside.

Step 2: Prepare the Chicken and Vegetables

While the macaroni cooks, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chopped chicken breast and cook until it’s no longer pink, about 5-7 minutes. Remove the chicken from the skillet and set aside.

Step 3: Sauté Bell Peppers and Onions

In the same skillet, add the sliced bell pepper and onion. Sauté for 3-4 minutes until they soften but still have a slight crunch.

Step 4: Add Fajita Seasoning and Tomatoes

Return the chicken to the skillet with the vegetables. Sprinkle the fajita seasoning packet over the mixture, stirring well to coat everything evenly. Pour in 1 cup of diced tomatoes and cook for another 2-3 minutes, allowing the flavors to meld.

Step 5: Mix the Cheese Sauce

In a large bowl, combine the cooked macaroni, chicken and vegetable mixture, 1/2 cup sour cream, 1 cup shredded cheddar cheese, and 1 cup Monterey Jack cheese. Stir gently until everything is well mixed.

Step 6: Assemble and Bake

Preheat your oven to 375°F (190°C). Transfer the macaroni mixture to a greased baking dish and spread it evenly. Top with a little extra cheese if you like. Bake for 15-20 minutes until the cheese is melted, bubbly, and golden on top.

Step 7: Garnish and Serve

Remove the dish from the oven and sprinkle 1/4 cup sliced green onions over the top for a fresh, crisp finish. Serve hot and enjoy!

Ingredient Flex Options

• Chicken: Swap chicken breast for chicken thighs for juicier meat or use turkey breast for a leaner option.
• Cheese: Try pepper jack for a spicier kick or mozzarella for a milder melt.
• Vegetables: Add sliced jalapeños for heat or substitute bell peppers with zucchini or mushrooms.
• Seasoning: Use homemade fajita seasoning or a smoky chipotle spice blend for variety.
• Sour Cream: Greek yogurt is a great substitute for a tangier, protein-packed twist.
• Pasta: Penne or shell pasta can replace elbow macaroni if preferred.

Frequent Missteps to Avoid

• Overcooking the pasta: Macaroni should be al dente to avoid mushiness after baking.
• Skipping the sauté step: Cooking the chicken and vegetables before baking ensures even flavor distribution and proper texture.
• Not seasoning the chicken well: The fajita seasoning is key for flavor, so don’t skimp on it.
• Overfilling the baking dish: Leave some space so the cheese can bubble and brown nicely without spilling over.

Freezer-Friendly Notes

This Cheesy Baked Chicken Fajita Mac freezes beautifully for make-ahead meals. After baking, allow it to cool completely, then portion into airtight containers. It can be frozen for up to 3 months. To reheat, thaw overnight in the refrigerator and warm in a preheated oven at 350°F until heated through and bubbly. Add fresh green onions after reheating for the best flavor.

Quick Q&A

Can I make this recipe vegetarian?

Absolutely! Replace the chicken with sautéed mushrooms, extra bell peppers, or plant-based protein substitutes to keep it hearty and flavorful.

What’s the best way to get a crispy top on my baked mac?

Sprinkle extra cheese or even some panko breadcrumbs on top before baking. Broil for the last 2-3 minutes to achieve a golden crust, but watch carefully to avoid burning.

Can I prepare this dish ahead of time?

Yes! Assemble the mac mixture and refrigerate it for up to 24 hours before baking. Just add a few extra minutes to the bake time if baking straight from the fridge.

How spicy is this dish?

The heat level depends on the fajita seasoning you use. Most store-bought packets are mild to medium. For more spice, add cayenne or hot paprika to taste.
