Once your onions are looking fabulous, add sliced mushrooms and minced garlic to the pan. Stir them around for a few minutes until everything gets cozy and fragrant.

While those veggies are sizzling away, season your boneless chicken breasts with salt, pepper, and fresh thyme. Then nestle them right into that pan so they can absorb all those glorious flavors.

In a bowl, mix together beef broth and balsamic vinegar. Pour this luscious mixture over everything in the skillet. It’s going to be saucy—just how we like it!

Step 6: Bake It All Together

Transfer your skillet to the preheated oven and let it bake for about 25-30 minutes or until your chicken reaches an internal temperature of at least 165°F (75°C).
