Ingredients:
- 1 lb lean ground turkey
- 1 tablespoon olive oil
- ½ onion, diced
- 2 cloves garlic, minced
- 2–3 medium zucchinis, thinly sliced or chopped
- 1 (14.5 oz) can diced tomatoes (drained slightly)
- 1 cup tomato sauce or marinara
- 1 teaspoon Italian seasoning
- Salt and pepper, to taste
- 1 cup shredded mozzarella cheese
- ¼ cup grated parmesan cheese
- 1 egg (optional, for binding if you layer like lasagna)
- Optional garnish: fresh basil or parsley
Preparation:
Step 1: Preheat Oven
- Preheat your oven to 375°F (190°C). Lightly grease a 9×9 or 9×13 baking dish depending on how thick you want the layers.
Step 2: Cook the Turkey Mixture
- In a large skillet, heat olive oil over medium heat. Add diced onion and cook for 2–3 minutes until softened. Stir in garlic and cook another 30 seconds.
- Add ground turkey and cook until browned and cooked through, breaking it up as it cooks. Season with salt, pepper, and Italian seasoning.
- Add the diced tomatoes and tomato sauce. Simmer for 5–7 minutes until slightly thickened.
Step 3: Prep the Zucchini
- While the turkey mixture simmers, slice the zucchini into thin rounds or half-moons. You can also dice it if you prefer a chunkier texture. Pat dry with paper towels to reduce moisture.
Step 4: Assemble the Casserole
- In the prepared baking dish, layer half of the turkey mixture, then add half the zucchini. Sprinkle with a bit of both cheeses. Repeat layers, ending with cheese on top.
- For a more structured casserole (like lasagna), you can beat one egg and mix it into the bottom layer of turkey for better sliceability.
Step 5: Bake
- Cover the dish loosely with foil and bake for 25 minutes. Remove the foil and bake for another 10–15 minutes until the cheese is golden and bubbly and the zucchini is tender.
Step 6: Cool and Serve
- Let the casserole rest for 5–10 minutes before serving to help everything set. Garnish with chopped basil or parsley.
Variation:
- Add more veggies: Mushrooms, spinach, or bell peppers work well in the filling.
- Spicy twist: Add crushed red pepper flakes or diced jalapeños.
- Creamy style: Stir in ½ cup ricotta or cream cheese for a creamy texture.
- Low-fat version: Use low-fat cheese and skip extra oil.
- Keto-friendly: Use no-sugar-added tomato sauce and go light on the onion.
COOKING Note:
Zucchini releases a lot of water as it cooks. To avoid a watery casserole, salt and pat dry the slices, or pre-cook them for a few minutes in the microwave or sauté pan before assembling.
Serving Suggestions:
- With a green salad: Light and refreshing side that pairs perfectly.
- Garlic bread: If not watching carbs, serve with crusty bread.
- For meal prep: Store in containers for easy lunches or dinners all week.
- With rice or quinoa: Make it heartier with a scoop of grains underneath.
Tips:
- Use lean ground turkey (93%) for the best balance of moisture and flavor.
- Don’t overbake—the zucchini should be just tender, not mushy.
- Add a bit of shredded cheddar for a cheesier flavor punch.
- Bake uncovered at the end for a crispy, golden cheese top.
