Chicken breast in mushroom sauce

Season chicken breasts with salt and pepper on both sides.
Heat olive oil in a large skillet over medium-high heat. Add chicken breasts and cook for 5-6 minutes on each side until browned and cooked through. Remove from pan and set aside.
In the same skillet, add chopped onion and cook until translucent, about 3-4 minutes
Add chopped garlic and chopped mushrooms. Cook for 5-7 minutes until the mushrooms release their moisture and begin to brown.
Sprinkle flour over the mushroom mixture and stir to combine. Cook for 1 minute to remove the raw flour taste.
Slowly pour in the chicken broth while stirring constantly to avoid lumps.
Add heavy cream, dried thyme, and a pinch of salt and pepper. Stir to combine.
Bring the sauce to a simmer and cook for 5 minutes until it begins to thicken.
