BBQ Cheddar Chicken Sandwich Ingredients
- 8 frozen onion rings
- 4 boneless chicken breasts (approximately 2 lbs)
- 1 cup BBQ sauce
- 1 tablespoon olive oil
- 1 cup baby bella mushrooms, sliced
- 4 oz cheddar cheese, sliced (about 1 oz per sandwich)
- 4 hamburger buns
Instructions
- Preheat the oven to 400°F (200°C).
- Arrange the frozen onion rings in a single layer on a baking sheet. Bake for 10 minutes, flip the rings, then bake another 8–10 minutes or until golden and crispy.
- While the onion rings bake, place the chicken breasts in a shallow bowl and toss them with the BBQ sauce until well coated.
- Heat a cast-iron skillet or heavy frying pan over medium-high heat. Add the BBQ-coated chicken breasts and cook 7–8 minutes per side, or until the internal temperature reaches 165°F (74°C) and the chicken is nicely browned.
- In a separate skillet, heat the olive oil over medium heat. Add the sliced baby bella mushrooms and sauté 5–7 minutes, stirring occasionally, until they are tender and lightly browned. Season with a pinch of salt and pepper to taste.
- When the chicken is nearly done, top each breast with about 1/4 cup of the sautéed mushrooms and two onion rings. Place a slice of cheddar on each chicken breast.
- Transfer the skillet (or move the chicken to a small baking sheet) to the oven for 2–3 minutes, just long enough to melt the cheese.
- Assemble the sandwiches: place each loaded chicken breast on a hamburger bun, close, and serve immediately.
Serving Suggestions and Tips
- Serve with a crisp green salad, coleslaw, or sweet potato fries to complement the BBQ flavors and crunchy onion rings.
- If you prefer a spicier sandwich, stir a few tablespoons of hot sauce into the BBQ sauce before coating the chicken.
- For a lighter version, use grilled chicken breasts and bake the onion rings until very crisp, or swap the cheddar for a lower-fat cheese.
- Leftover sandwich components keep well: store chicken and mushrooms in separate airtight containers in the fridge for up to 3 days.
