Choosing the perfect Ingredients for Maximum Taste and Texture
Start with boneless, skinless chicken breasts or thighs for juicy, tender meat that soaks up the fajita seasoning beautifully. Use a colorful trio of bell peppers-red, green, and yellow-to add sweetness and crunch, balanced by the caramelized depth of sliced onions.Fresh garlic and a blend of spices such as smoked paprika, cumin, chili powder, and oregano create the bold, zesty undercurrent. Don’t skimp on the fresh lime juice-the brightness it adds pulls the entire dish together.

- Cheese: Use a sharp cheddar or a Mexican blend for creamy, melty goodness.
- Tortillas: Slightly toasted flour tortillas layered in the casserole add satisfying texture and soak in all the fajita juices.
