Layer the sliced mushrooms and chopped onion at the bottom of your slow cooker.
Place the chicken breasts on top of the mushroom and onion mixture.
In a separate bowl, mix together the garlic, diced tomatoes (with juices), chicken broth, balsamic vinegar, oregano, basil, salt, black pepper, and optional red pepper flakes.
Pour the mixture evenly over the chicken.
Cover and cook:
Low for 6–7 hours
High for 3–4 hours
Once fully cooked, top with fresh parsley and a generous sprinkle of grated Parmesan cheese.
✨ Variations & Tips
Thicker Sauce: Mix 1 tablespoon cornstarch with 2 tablespoons water and stir in during the last 30 minutes.
Extra Veggies: Add chopped bell peppers or zucchini in the final hour.
Prefer Dark Meat? Use chicken thighs instead—just adjust cooking time slightly.
Mushroom Lovers: Use a mix like portabella or porcini for richer depth.
Creamy Option: Stir in a splash of heavy cream or mascarpone before serving for extra richness.
