Method
Season and sear the chicken
- Season the boneless skinless chicken breasts with garlic powder, onion powder, salt, and black pepper. Make sure both sides are evenly coated for consistent flavor.
- Heat the olive oil in an oven-safe cast iron skillet over medium-high heat and sear the chicken for 5–6 minutes per side until golden. Transfer the chicken to a plate to rest while you cook the mushrooms and onions.
Smother with mushrooms and onions
- Melt the butter in the same skillet, then add the sliced onions and sliced mushrooms. Cook over medium heat for 8–10 minutes until caramelized, stirring occasionally so the vegetables brown.
- Pour in the chicken broth and stir to deglaze, scraping up the browned bits from the bottom of the skillet. Let the liquid bubble briefly to form a glossy base.
- Nestle the seared chicken back into the skillet on top of the mushroom-onion mixture. Arrange it so the toppings stay pooled under the chicken.
- Pile the shredded Monterey jack cheese generously on top of each chicken breast. Add enough to fully cover the surface so it melts and turns bubbly.
Broil and serve
- Place the skillet under the broiler for 3–4 minutes until the cheese is melted and bubbly. Watch the top closely so it browns lightly without burning.
- Garnish with fresh parsley right after broiling. Serve immediately while the pan juices are hot and the cheese is set but still melty.
Notes
For extra even cooking, pound the chicken to a consistent thickness so each breast reaches the same golden-brown sear time. Store leftovers in an airtight container in the refrigerator up to 3 days; reheat gently in a skillet over low heat until warmed through. Freezing is not recommended because the cheese and vegetables can lose texture. If you want a lighter option, use reduced-fat Monterey jack to lower calories while keeping the smothered, bubbly finish.
