Ingredients

2 lbs boneless, skinless chicken breasts or thighs, thinly sliced
3 tbsp olive oil, divided
3 bell peppers (red, yellow, green), sliced
1 large yellow or white onion, thinly sliced
1/4 cup lime juice
1 tbsp chili powder
2 tsp ground cumin
1 tsp smoked paprika
1 tsp garlic powder
1/2 tsp onion powder
1/2 tsp dried oregano
1/4 tsp cayenne pepper
1 tsp salt
1/2 tsp black pepper
2 tbsp unsalted butter
2 tbsp all-purpose flour
1.5 cups whole milk or half-and-half
8 oz Monterey Jack cheese, freshly grated
4 oz mild cheddar cheese, freshly grated
2-3 tbsp diced canned green chilies
Pinch of salt and white pepper
Optional: dash of hot sauce
12-16 small flour or corn tortillas
Fresh cilantro, chopped
Avocado slices or guacamole
Sour cream or Greek yogurt
Lime wedges

Instructions

Step 1: Pat chicken strips dry. In a bowl, toss chicken with 1 tablespoon olive oil, 2 tablespoons lime juice, and two-thirds of the fajita seasoning blend (chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne, salt, black pepper). Marinate for 15 to 60 minutes.
Step 2: Slice bell peppers and onion. Grate Monterey Jack and cheddar cheeses. Measure out milk, butter, flour, and open the canned green chilies. Set aside the remaining one-third of the fajita seasoning for the vegetables.
Step 3: Heat 1 tablespoon olive oil in a large, heavy-bottomed skillet over medium-high heat until shimmering. Add about half of the marinated chicken in a single layer. Sear for 3 to 4 minutes per side until deeply golden, slightly charred, and cooked through (internal temperature 165°F / 74°C). Remove to a plate and tent with foil. Repeat with the remaining chicken.
Step 4: Add the final 1 tablespoon olive oil to the same skillet. Add sliced onions and bell peppers. Sauté for 5 to 7 minutes over medium-high heat, stirring occasionally, until tender-crisp with some charred edges. Sprinkle with the remaining one-third fajita seasoning blend and toss well. Cook for another 1 to 2 minutes to allow the spices to bloom.
Step 5: Return the cooked chicken to the skillet with the vegetables. Toss everything gently to combine. Remove the skillet from heat momentarily.
Step 6: In a separate medium saucepan, melt 2 tablespoons unsalted butter over medium heat. Sprinkle in 2 tablespoons all-purpose flour and whisk continuously for 1 to 2 minutes to create a smooth, pale yellow roux.
Step 7: Slowly pour in 1.5 cups whole milk (or half-and-half), whisking constantly to prevent lumps. Bring to a gentle simmer and whisk until thickened, about 3 to 5 minutes. Reduce heat to low. Gradually add freshly grated Monterey Jack and mild cheddar cheeses a handful at a time, whisking constantly until each addition is fully melted and smooth. Avoid adding all the cheese at once.
Step 8: Once the queso is smooth and glossy, stir in 2 to 3 tablespoons diced canned green chilies, a pinch of salt, white pepper, and an optional dash of hot sauce. Keep the queso warm over very low heat, stirring occasionally.
Step 9: Return the skillet with chicken and vegetables to medium-low heat if cooled. Pour the warm, creamy queso directly over the mixture. Gently fold and stir everything together, ensuring the chicken and veggies are evenly coated. Avoid overcooking once queso is added.
Step 10: Warm tortillas in a dry skillet, oven, or microwave. Bring the sizzling skillet of Queso Chicken Fajitas directly to the table. Serve with warmed tortillas, fresh chopped cilantro, avocado slices or guacamole, sour cream or Greek yogurt, and extra lime wedges for building custom fajitas.

Tips & Variations

Use chicken thighs for more flavor and juiciness, or breasts for leaner meat.
Adjust the cayenne and hot sauce to your preferred spiciness level.
Swap the Monterey Jack with Pepper Jack for a spicy kick.
Try adding mushrooms or zucchini to the vegetables for extra variety.
For a dairy-free version, substitute cheese with vegan cheese and use coconut or almond milk.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat to prevent the queso from separating. Add a splash of milk to loosen the sauce if needed. Tortillas are best warmed fresh for serving.

How to Serve

A white bowl holds a colorful dish with three main layers. The bottom layer is orange rice mixed with strips of green and red bell peppers. On top, there are chunks of brown grilled chicken pieces scattered evenly. The chicken is covered with a creamy, light yellow sauce drizzled over to make it look smooth. Small bits of green herbs sprinkle over the sauce to add a touch of color. In the background, there is a shiny pan with more orange rice, and everything sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use frozen chicken for this recipe?

It’s best to use fresh or fully thawed chicken for even cooking. If using frozen, thaw completely and pat dry before marinating to ensure proper searing and flavor absorption.

What if I don’t have all the spices for the fajita seasoning?

You can substitute with a pre-made fajita or taco seasoning mix. Adjust the quantities to taste and keep the salt to about 1 teaspoon in total to avoid over-seasoning.
