Ingredients for a Chicken Fajita Bake

  • 2 pounds chicken breast, sliced into strips
    • For this chicken fajitas recipe, slice the chicken into strips so it cooks evenly with the rice. Alternatively, slice it horizontally for a thin chicken breast that will also cook more quickly.
  • 3 bell peppers, sliced
    • Use 2-3 peppers, depending on their size and preference. We are a bell pepper-loving family and use 3 bell peppers every time.
  • 1 medium onion, sliced
  • 1 ounce packet of fajita seasoning or taco seasoning
    • For a stronger flavor, use 1 1/2 to 2 packets. My teenagers and husband prefer two packets. For younger children who are sensitive to spice, stick to one packet.
  • 2 Tablespoons olive oil
  • 3/4 cup long-grain rice, uncooked, not instant
  • 1 1/2 cups chicken broth
    • We often use Better Than Bouillon chicken base. It’s an easy way to keep chicken(and beef) stock on hand for recipes.
  • 2 cups shredded cheddar cheese, optional if dairy-free
    • I shred my cheese with this cheese grater(click here to view), which I found on Amazon. It works well. I love the simple design. It comes with many barrels for veggies and cheese. I love that it’s a non-electric cheese grater. No worries when my kids clean it, and we can shred cheese anywhere. No fighting over outlets! It’s a thing here.
