Step 1: Prep the Chicken

Start by prepping the chicken breasts. If they’re particularly thick, it’s a good idea to pound them to an even thickness to ensure they cook evenly.

Step 2: Marinade the Chicken

In a medium-sized bowl, combine soy sauce, lemon juice, Worcestershire sauce, minced garlic, and smoked paprika. Place the chicken breasts in the marinade and let them sit for at least 30 minutes to absorb all the flavors. For an extra flavor boost, let it marinate for a few hours in the refrigerator.

Step 3: Sauté the Onions and Mushrooms

While the chicken is marinating, heat olive oil in a skillet over medium heat. Add sliced onions and sauté for about 3-4 minutes until they begin to soften. Next, add the sliced mushrooms and continue cooking until the onions and mushrooms are tender and caramelized. Remove them from the skillet and set them aside.

Step 4: Cook the Chicken

In the same skillet, add a tablespoon of butter and allow it to melt over medium-high heat. Place the marinated chicken breasts in the skillet and cook for about 5-7 minutes on each side or until the internal temperature reaches 165°F. Be sure to season with salt and pepper while cooking.

Step 5: Add the Cheese

Once the chicken is nearly cooked through, place a slice of Monterey Jack cheese on each chicken breast. Cover the skillet with a lid for 1-2 minutes, allowing the cheese to melt to perfection.

Step 6: Smother the Chicken

Top each cheesy chicken breast with the sautéed onions and mushrooms. Let the flavors meld together for another minute or two, and voilà—your dish is ready!
