Instructions
- Prepare & Marinate Chicken: Pat chicken strips dry. In a bowl, toss chicken with 1 tbsp olive oil, 2 tbsp lime juice, and 2/3 of the fajita seasoning blend (chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne, salt, black pepper). Marinate for 15-60 minutes to infuse flavors and tenderize the meat.
- Prep Vegetables & Queso Ingredients: Slice bell peppers and onion. Grate Monterey Jack and cheddar cheeses for the queso. Measure out milk, butter, flour, and open diced green chilies. Set aside the remaining 1/3 fajita seasoning to season the vegetables later.
- Sear Chicken: Heat 1 tbsp 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 3-4 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 remaining chicken.
- Cook & Season Vegetables: Add the final 1 tbsp olive oil to the same skillet. Add sliced onions and bell peppers. Sauté for 5-7 minutes over medium-high heat, stirring occasionally, until tender-crisp with some charred edges. Sprinkle with the remaining 1/3 fajita seasoning blend and toss well. Cook for another 1-2 minutes to bloom the spices.
- Combine Fajitas: Return the cooked chicken to the skillet with the vegetables. Toss everything gently to combine. Remove the skillet from heat momentarily to prepare the queso sauce.
- Prepare the Queso Roux: In a separate medium saucepan, melt 2 tbsp unsalted butter over medium heat. Sprinkle in 2 tbsp all-purpose flour and whisk continuously for 1-2 minutes until smooth and pale yellow, forming the base for the queso sauce.
- Whisk in Milk & Melt Cheese for Queso: 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 the sauce thickens, about 3-5 minutes. Reduce heat to low. Gradually add freshly grated Monterey Jack and mild cheddar cheeses, a handful at a time, whisking constantly until fully melted and smooth.
- Finish & Season Queso: Once the queso is creamy and glossy, stir in 2-3 tbsp 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 to maintain smoothness.
- Combine Queso with Fajitas: Return the skillet with chicken and vegetables to medium-low heat if it has cooled. Pour the warm queso sauce directly over the mixture. Gently fold and stir everything together to coat the chicken and veggies evenly, being careful not to overcook.
- Serve Immediately: Warm the tortillas in a dry skillet, oven, or microwave. Serve the sizzling Queso Chicken Fajita skillet with warm tortillas, fresh chopped cilantro, avocado slices or guacamole, sour cream or Greek yogurt, and lime wedges for guests to build their own fajitas.
Notes
- Marinate the chicken for at least 15 minutes but up to 1 hour for maximum flavor.
- Adjust the cayenne pepper and hot sauce to control spice level.
- Use half-and-half instead of whole milk in the queso for a richer sauce.
- For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend in the roux and use corn tortillas.
- Leftover fajitas can be refrigerated for up to 3 days and reheated gently to preserve the creamy sauce.
- For crispier chicken, avoid overcrowding the skillet when searing and cook in batches.
- Fresh lime juice added during marination and serving brightens the flavors beautifully.
