Ingredients
Meat and Vegetables
- 1 lb ground turkey
- 2 medium zucchinis, sliced
- 1/2 cup chopped onion
- 2 cloves garlic, minced
- 1 can (14 oz) diced tomatoes, drained
Dairy
- 1 cup shredded mozzarella cheese
Seasonings and Oils
- 1 tsp dried Italian herbs
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 tbsp olive oil
Instructions
- Preheat oven and prepare dish. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil to prevent sticking and to add flavor.
- Sauté aromatics. In a large skillet over medium heat, heat olive oil and add chopped onion and minced garlic. Sauté them for about 2 minutes until fragrant and translucent, which will build the base flavor for the casserole.
- Cook ground turkey. Add ground turkey to the skillet and cook for 5-6 minutes, stirring and breaking it up with a spoon until fully browned and no longer pink.
- Add tomatoes and seasonings. Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Let the mixture simmer gently for 3-4 minutes to allow the flavors to meld together.
- Assemble the casserole layers. Spread half of the sliced zucchini evenly in the prepared baking dish. Layer half of the cooked turkey mixture over the zucchini, followed by half of the shredded mozzarella cheese. Repeat the layering with the remaining zucchini, turkey mixture, and mozzarella cheese on top.
- Bake the casserole. Place the casserole dish uncovered in the preheated oven and bake for 30-35 minutes. The casserole is done when it is bubbly and the cheese on top turns golden brown.
- Cool and serve. Remove the casserole from the oven and allow it to cool for about 5 minutes before serving. This resting time lets the casserole set for easier serving and enhances the flavors.
Notes
- You can substitute ground chicken or turkey sausage if preferred.
- For extra flavor, add a pinch of red pepper flakes when cooking the turkey.
- You can use shredded cheddar or a blend of Italian cheeses instead of mozzarella.
- Make sure to slice zucchini evenly for uniform cooking.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven.
