I enjoy this recipe because it checks all the right boxes for a busy day. It is easy to prepare, uses simple ingredients, and comes together in one dish.

ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 lb (450 g) ground turkey
1 tablespoon olive oil
1 small onion, diced
2 cloves garlic, minced
1 cup (150 g) cooked rice or quinoa
1 can (14 oz / 400 g) diced tomatoes, drained
1 cup (150 g) frozen mixed vegetables (peas, carrots, corn)
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon paprika
1/2 teaspoon dried oregano
1/2 teaspoon chili flakes (optional)
1/2 cup (120 ml) low-sodium chicken broth
1 cup (100 g) shredded mozzarella cheese
1/2 cup (50 g) shredded cheddar cheese
2 tablespoons chopped fresh parsley (optional, for garnish)
directions
I start by preheating the oven to 375°F (190°C). Then I heat olive oil in a large skillet over medium heat. I add the diced onion and cook until it softens, then stir in the garlic for about 30 seconds.
Next, I add the ground turkey and cook it until browned, breaking it apart as it cooks. Once the turkey is fully cooked, I mix in the salt, pepper, paprika, oregano, and chili flakes.
I stir in the diced tomatoes, cooked rice or quinoa, mixed vegetables, and chicken broth. I let everything simmer for about 5 minutes so the flavors come together.
I transfer the mixture into a greased baking dish and spread it evenly. Then I sprinkle mozzarella and cheddar cheese on top.
I bake the casserole for 20–25 minutes, until the cheese is melted and bubbly. I like to let it rest for a few minutes before serving, then finish with fresh parsley if I have it.
Servings and timing
I usually get about 4 to 6 servings from this casserole.
Prep time: 10 minutes
Cook time: 30 minutes
Total time: 40 minutes
Variations
I sometimes switch the rice for cauliflower rice when I want a lower-carb option. I also like adding spinach or zucchini for extra vegetables. If I want more spice, I increase the chili flakes or add a dash of hot sauce. For a creamier version, I mix in a little Greek yogurt or light cream before baking.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 4 days. When I reheat it, I use the microwave for convenience or warm it in the oven at 350°F (175°C) until heated through. If it seems a bit dry, I add a splash of broth before reheating.
FAQs
Can I freeze this casserole?
I freeze it either before or after baking. I wrap it tightly and store it for up to 2 months. I thaw it overnight in the fridge before reheating.
Can I use a different type of meat?
I sometimes substitute ground chicken or lean ground beef. Both work well, though the flavor changes slightly.
Is this recipe good for meal prep?
I find it perfect for meal prep since it stores well and reheats easily. I portion it into containers for quick lunches.
Can I make it dairy-free?
I skip the cheese or use a dairy-free alternative. It still tastes great because of the seasoned turkey and vegetables.
How do I make it more filling?
I add extra grains like quinoa or beans to boost the fiber and protein, making it even more satisfying.

I keep coming back to this high protein ground turkey casserole because it is simple, reliable, and always satisfying. It is one of those meals I can count on when I want something hearty without spending too much time in the kitchen.
