Brown Rice Casserole with Turkey, Peppers, Mushrooms, and Feta
This Brown Rice Casserole with Turkey, Peppers, Mushrooms, and Feta is delicious and easy to make.

Ingredients
- 1 1/2 cups cooked brown rice
- 6 tsp. olive oil, divided
- 1 lb. brown Cremini mushrooms
- 1 medium onion, chopped into smallish pieces
- 1 green pepper, seeds removed and chopped into smallish pieces
- 1 tsp. Greek seasoning
- 1 tsp. Greek oregano
- 1 1/2 lb. ground turkey
- salt and fresh-ground black pepper to taste
- 2/3 cup sour cream
- 1/3 cup chicken stock
- 3/4 cup crumbled Feta
- 8 oz. grated Mozzarella
Directions
- Cook brown rice according to package directions. (I cooked the maximum amount in my Zojirushi 3-Cup Rice Cooker (affiliate link) and froze the extra for another time.)
- Preheat oven to 375F/190C.
- Spray a glass or crockery casserole dish with non-stick spray. (I used my favorite 12 cup glass casserole dish, but you can also use a rectangular dish and make a slightly flatter casserole.)
- Wash mushrooms if needed and cut into thick slices or half slices.
- Heat about 2 tsp. oil in a large non-stick frying pan and saute the mushrooms over medium-high heat until they’re slightly browned and all liquid has evaporated, about 5 minutes.
- Put mushrooms into a large plastic bowl.
- Heat a little more oil in the frying pan, add the chopped onion and green pepper, and cook over medium-high heat until the onion and peppers are starting to slightly brown.
- Add the Greek seasoning and Greek oregano and cook about 1 minute more.
- Add the vegetables to the mushrooms in the bowl.
- Heat a little more oil in the pan, add the ground turkey, and cook over medium-high heat until the turkey is nicely browned and any water that’s released has completely evaporated. (Nearly all ground turkey will release some water, even if you buy high-quality ground-in-store turkey.)
- This will take about 10 minutes; don’t rush the browning.
- Season the turkey with a little salt and fresh-ground black pepper and break apart with a turner as it cooks. (I like to use a potato masher to break the cooked turkey into small pieces.)
- Add the browned turkey to the bowl with the vegetables.
- Stir the cooked brown rice into the turkey/vegetable mixture.
- In a small bowl mix together the low-fat sour cream, chicken stock, crumbled Feta, and 3/4 cup of the reduced-fat Mozzarella.
- Gently mix the sour cream mixture into the rice/meat/vegetables mixture.
- Put it into the sprayed casserole dish and spread around so it’s slightly pressed down and flat.
- Top with the other 1 1/4 cups grated low-fat Mozzarella.
- Bake covered for 20 minutes, then remove the lid (or foil) and bake another 20 minutes, or until the top is nicely browned and the whole casserole is bubbling.
- Serve hot.
