When the weather is cold I’m always thinking about Casseroles because I love the way you can cook once and then eat the leftovers several times. And when the idea popped into my mind to make a ground turkey casserole that was really amazing, I worked on this Ground Turkey Rice Casserole for a few weeks to get the flavors I thought were just perfect! Although this recipe does use brown rice, there’s a lot of ground turkey, green pepper, mushrooms, Mozzarella, and Feta and just a little bit of brown rice for a relatively carb-conscious casserole with rice. I tried it out on several people who all said it was a keeper!

Of course I know some of my readers wouldn’t make a casserole with rice, so check out my ultra-popular Low-Carb Turkey Casserole that uses cauliflower rice or Low-Carb Turkey Enchilada Casserole if you’re looking for a casserole with turkey that’s extra low in carbs!

What ingredients do you need for this recipe?

Can you make this recipe with leftover turkey?

You could definitely make this recipe with leftover cooked turkey; just use about 3 cups of diced turkey in place of the ground turkey. Or check out my Leftover Turkey Casserole for a more traditional turkey casserole idea.

How to make this ground turkey casserole:

(Scroll down for complete printable recipe including nutritional information.)

  1. I used my Zojirushi 3-Cup Rice Cooker (affiliate link) to cook the brown rice. (I only used part of it, and froze some rice for another time.)
  2. While rice cooks, wash mushrooms, cut into slices or half slices, and cook until nicely browned. Put mushrooms in a large bowl.
  3. Chop onions and green pepper, cook until starting to brown, then add Greek Seasoning (affiliate link) and Greek oregano and cook a few minutes more. Put the veggies into the bowl with the mushrooms.
  4. Heat a little more oil in the frying pan and cook the ground turkey until it’s nicely browned. Put the browned turkey into the bowl. Season the meat with a little salt and fresh-ground black pepper.
  5. When the rice is cooked, mix in 1 1/2 cups cooked brown rice.
  6. I used both Mozzarella and Feta to give the casserole plenty of cheesy flavor.
  7. Mix together the sour cream, chicken stock, 3/4 cup crumbled Feta, and 3/4 cup grated Mozzarella.
  8. Gently fold the sour cream/cheese mixture into the rice/meat/vegetables mixture.
  9. Put the mixture into a glass or crockery casserole dish and sprinkle with the other 1 1/4 cups cheese.  (I used my favorite 12 cup glass casserole dish, but anything close to that size will work.)
  10. Bake the casserole at 375F/190C with the lid on (or covered with foil) for the first 20 minutes. Here’s how it looks when you take off the lid. 
  11. Put back in the oven and bake about 20 minutes more, or until the top is nicely browned and the casserole is bubbling. Serve hot.
  12. This keeps well in the fridge and freezes well, and it can be reheated either in a covered dish in the oven or in the microwave.

Ground Turkey Rice Casserole

Prep Time 45 minutes
Cook Time 40 minutes
Total Time 1 hour 25 minutes

This Ground Turkey Rice Casserole has brown rice, mushrooms, green pepper, Mozzarella, and Feta for a ground turkey casserole that's truly delicious and also easy to make.

Ingredients

  • 1 1/2 cups cooked brown rice
  • 6 tsp. olive oil, divided (more or less depending on your pan)
  • 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 broth
  • 3/4 cup crumbled Feta
  • 8 oz. grated Mozzarella

Instructions

  1. 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.)
  2. 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.)
  3. Wash mushrooms if needed and cut into thick slices or half slices.
  4. 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.
  5. 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.
  6. Add the Greek Seasoning (affiliate link) and Greek oregano and cook about 1 minute more.  Add the vegetables to the mushrooms in the bowl.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.

Notes

This keeps for several days in the refrigerator and also freezes well.  It can be reheated in a tightly covered dish in the oven or in the microwave.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
This Ground Turkey Rice Casserole has 19 net carbs in a small serving, so it may be too much of a splurge for low-carb diets. But it’s loaded with low-glycemic ingredients and will work for Phase 2 or 3 for the original South Beach Diet. It’s recommended to use lean ground turkey and reduced-fat cheese for South Beach. For a lower-carb casserole with these flavors, I would use more turkey and peppers and less rice, or check out my Low-Carb Turkey Casserole for a turkey casserole that uses cauliflower rice.
