Recipe Information
Ingredients
- 1.5 pounds Chicken breasts or thighs (boneless, skinless)
- 1 cup Brown rice
- 2.5 cups Chicken broth (low sodium)
- 8 ounces Cremini or button mushrooms (sliced)
- 1 medium Onion (diced)
- 3 cloves Garlic (minced)
- 2 medium Carrots (sliced)
- 2 stalks Celery (sliced)
- 1 teaspoon Fresh thyme (or 1/2 teaspoon dried thyme)
- 2 tablespoons Fresh parsley (chopped, for garnish)
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 1 tablespoon Olive oil
- 0.25 cup Grated Parmesan cheese (optional, for serving)
Instructions
Heat the olive oil in a large skillet over medium-high heat. Sear the chicken breasts or thighs for 2-3 minutes per side until lightly browned. This step is optional but adds extra flavor.
Spray the inside of the slow cooker with nonstick cooking spray or use a liner for easy cleanup.
Add the brown rice and chicken broth to the bottom of the slow cooker, spreading evenly.
Layer the seared chicken on top of the rice.
Add the sliced mushrooms, diced onion, minced garlic, sliced carrots, and sliced celery on top of the chicken.
Sprinkle the salt, black pepper, and thyme over the vegetables.
Cover the slow cooker with its lid and cook on high for 3-4 hours or on low for 6-7 hours, until the chicken is tender, the rice is cooked through, and the liquid is absorbed.
Once the cooking time is complete, stir the casserole gently to mix the ingredients. Taste and adjust seasoning with more salt and pepper if needed.
Serve hot, garnished with fresh chopped parsley and a sprinkle of grated Parmesan cheese if desired.
