Tex-Mex Zucchini Bake

Description

If you’re searching for a hearty, cheesy, and satisfying dinner that keeps the carbs low while delivering bold Tex-Mex flavors, this Tex-Mex Zucchini Bake is exactly what you need. Loaded with seasoned ground beef, tender zucchini, juicy cherry tomatoes, colorful bell peppers, fluffy eggs, and plenty of melted cheese, this one-pan casserole is the ultimate comfort food for busy weeknights and family dinners.

Unlike traditional casseroles that rely on pasta or tortillas, this recipe uses fresh zucchini as the main vegetable, making it naturally low in carbohydrates while adding freshness, texture, and nutrition. The zucchini absorbs the rich Tex-Mex seasonings beautifully, while the eggs help bind everything together into a soft, flavorful bake that’s easy to slice and serve.

Ground beef provides plenty of protein, while garlic, onions, cumin, smoked paprika, and chili powder create a delicious savory base with just the right amount of warmth. A blend of cheddar and mozzarella melts into a beautifully golden topping that becomes bubbly and slightly crispy around the edges during baking.

One of the best things about this recipe is how versatile it is. It works perfectly for breakfast, brunch, lunch, dinner, or meal prep. The leftovers taste just as delicious the next day, making it a great make-ahead meal for busy schedules.

Whether you’re following a low-carb lifestyle, trying to add more vegetables to your meals, or simply craving something cheesy and comforting, this Tex-Mex Zucchini Bake is guaranteed to become a family favorite.

Ingredients

For the Bake

2 medium zucchini, sliced into half-moons
1 pound (450g) lean ground beef
1 small onion, diced
3 cloves garlic, minced
1 cup cherry tomatoes, halved
1 cup diced yellow bell pepper
6 large eggs
½ cup heavy cream
1½ cups shredded cheddar cheese
1 cup shredded mozzarella cheese
2 tablespoons olive oil

Seasonings

1 teaspoon chili powder
1 teaspoon ground cumin
1 teaspoon smoked paprika
½ teaspoon garlic powder
½ teaspoon onion powder
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon dried oregano
2 tablespoons chopped fresh parsley

Instructions

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with olive oil.
Heat one tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and cook until softened, about 3 minutes. Stir in the garlic and cook for another 30 seconds until fragrant.
Add the ground beef and cook until browned, breaking it into small crumbles as it cooks. Drain any excess grease if necessary.
Season the beef with chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and black pepper. Stir well until the meat is evenly coated with the spices.
Add the sliced zucchini and diced bell pepper to the skillet. Cook for about 4 minutes until they begin to soften while still holding their shape.
Remove the skillet from the heat and gently fold in the cherry tomatoes.
Whisk together the eggs and heavy cream in a separate bowl until smooth.
Spread the beef and vegetable mixture evenly into the prepared baking dish.
Pour the egg mixture evenly over the top, allowing it to settle between the vegetables and meat.
Sprinkle the cheddar cheese evenly across the casserole, followed by the mozzarella cheese.
Bake uncovered for 35–40 minutes, or until the eggs are fully set and the cheese is melted, bubbly, and golden brown.
Broil for 2–3 minutes if you prefer a crispier, golden cheese topping.
Remove from the oven and let the casserole rest for 10 minutes before slicing.
Garnish with freshly chopped parsley and serve warm.
