Description
If you’re searching for a hearty, family-approved dish that’s loaded with comfort and flavor, this Mushroom and Chicken Rice Casserole is a must-try.
Ingredients
- 2 tablespoons olive oil or unsalted butter
- 1 small yellow onion, finely diced
- 8 oz white or cremini mushrooms, sliced
- 2 garlic cloves, minced
- 1½ lbs boneless, skinless chicken thighs or breasts, diced
- 1 cup long grain white rice (uncooked)
- 1½ cups chicken broth
- 1 cup milk (whole or 2%)
- 1 cup shredded mozzarella cheese
- 1 cup shredded cheddar cheese
- ½ teaspoon dried thyme
- Salt and pepper to taste
- Fresh parsley for garnish (optional)
Instructions
Step 1: Preheat your oven to 375°F (190°C). Lightly grease your 9×13-inch baking dish and set aside.
Step 2: In a large skillet, heat olive oil or butter over medium heat. Add diced onions and cook until softened, about 3–4 minutes.
Step 3: Stir in sliced mushrooms and cook for another 5–6 minutes, allowing them to release their moisture and brown slightly.
Step 4: Add garlic and diced chicken to the pan. Season with salt, pepper, and thyme. Cook until the chicken is lightly browned but not fully cooked through, about 4–5 minutes.
Step 5: Stir in uncooked rice, chicken broth, and milk. Let the mixture come to a gentle simmer, then remove from heat.
Step 6: Pour the entire mixture into the prepared casserole dish. Sprinkle the shredded cheeses evenly over the top.
Step 7: Cover tightly with foil and bake for 30 minutes. Then remove foil and bake for an additional 10–15 minutes, or until the cheese is bubbly and golden and the rice is tender.
Step 8: Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired.
Notes
- Use long grain white rice for best results. Short grain or instant rice will alter the texture.
- Don’t overcook the chicken in the skillet—it will finish cooking in the oven.
- For a smoother sauce, warm the milk slightly before mixing it in.
- If the casserole seems dry after baking, stir in a splash of warm broth before serving.
- Allow the casserole to rest before serving so the sauce can thicken and the rice can settle.
