Season chicken breasts with salt, pepper, paprika, and garlic powder.
Heat olive oil in a skillet over medium heat and sear chicken for 5–6 minutes per side until golden brown and cooked through (internal temp 165°F). Remove and set aside.
In the same skillet, add onions and mushrooms. Sauté until softened and caramelized (about 5–7 minutes).
Deglaze the pan with chicken broth and Worcestershire sauce, scraping any brown bits for flavor.
Return chicken to the skillet, top with the mushroom-onion mixture, and sprinkle both cheeses over the top.
Cover and cook on low until cheese is melted and bubbly (about 2–3 minutes).
Serve hot with a side of green beans or mashed cauliflower for a Texas-style feast!
