Ingredients

• 2 medium zucchinis, sliced
• 1 lb ground turkey
• 1 cup diced bell peppers (any color)
• 1 small onion, chopped
• 2 cloves garlic, minced
• 2 cups shredded cheddar cheese
• 1 can black beans, drained and rinsed
• 1 cup diced tomatoes
• 1 teaspoon cumin
• 1 teaspoon chili powder
• Salt and pepper to taste
• 1 tablespoon olive oil
• Fresh cilantro for garnish

How To Make Cheesy Zucchini Taco Casserole (Low carb)

Step 1: Prepare the Vegetables

Start by washing and slicing the zucchinis into thin rounds, about 1/4 inch thick. Dice the bell peppers and onion, and mince the garlic cloves. Having all your vegetables ready before cooking will make the process smooth and efficient.

Step 2: Cook the Ground Turkey and Vegetables

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and garlic, sautéing until fragrant and translucent, about 2-3 minutes. Add the ground turkey and cook, breaking it up with a spoon, until it’s no longer pink.

Step 3: Add the Seasonings and Veggies

Sprinkle in the cumin, chili powder, salt, and pepper, stirring well to combine. Next, add the diced bell peppers, black beans, and tomatoes to the skillet. Cook for another 5-7 minutes until the vegetables are tender and flavors meld. Taste and adjust seasonings if needed.

Step 4: Assemble the Casserole

Preheat your oven to 375°F (190°C). In a greased baking dish, layer half of the zucchini slices evenly on the bottom. Spread half of the turkey and vegetable mixture over the zucchini, then sprinkle one cup of shredded cheddar cheese on top. Repeat the layers with the remaining zucchini, turkey mixture, and cheese.

Step 5: Bake Until Bubbling and Golden

Place the casserole in the oven and bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown. The zucchini should be tender but still hold its shape.

Step 6: Garnish and Serve

Remove the casserole from the oven and let it cool slightly. Garnish with freshly chopped cilantro for a burst of color and freshness. Serve warm and enjoy!

Expert Tips

• For extra flavor, consider adding a splash of lime juice to the turkey mixture before assembling the casserole.
• Using a mandoline slicer to cut the zucchini ensures evenly thin slices, which helps the casserole cook uniformly.
• If you want a bit more spice, add a pinch of cayenne pepper or some diced jalapeños when cooking the turkey.
• Drain and rinse the black beans thoroughly to reduce sodium and improve texture.
• To prevent the casserole from becoming watery, avoid slicing the zucchini too thick and consider patting the slices dry with paper towels before assembling.
• Leftover casserole can be reheated in the microwave or oven—just sprinkle a little extra cheese on top to refresh the gooey texture.

Variations and Customizations

• Meat Alternative: Swap ground turkey for ground chicken, beef, or even a plant-based meat substitute to suit your preferences.
• Cheese Options: Try pepper jack for a spicy kick or mozzarella for a milder, creamier melt.
• Additional Veggies: Add corn kernels, chopped zucchini flowers, or even spinach to boost the veggie content.
• Beans: Replace black beans with pinto or kidney beans if you prefer.
• Toppings: Top with sliced avocado, a dollop of sour cream, or a sprinkle of diced green onions just before serving.
• Make it Vegan: Use crumbled tofu or tempeh instead of turkey and vegan cheese alternatives to make this dish plant-based.

How to Store Leftovers

Store any leftover Cheesy Zucchini Taco Casserole (Low carb) in an airtight container in the refrigerator for up to 3-4 days. When you’re ready to enjoy it again, reheat in the microwave or oven until warmed through. If reheating in the oven, cover the casserole with foil to prevent the cheese from burning and remove the foil in the last few minutes to crisp up the top.

For longer storage, you can freeze the casserole in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating. Freezing may slightly change the texture of the zucchini but the flavors will stay delicious.

FAQ

Can I use other types of cheese in this casserole?
