Ingredients

2 cups cooked chicken breast, shredded or diced

2 cups broccoli florets

2 cups cauliflower florets

1 tablespoon olive oil

1 small onion, finely chopped

2 cloves garlic, minced

1 cup cottage cheese

1 cup shredded cheddar cheese

1 cup mozzarella cheese, divided

1/2 cup sour cream

2 large eggs

1 teaspoon onion powder

1/2 teaspoon garlic powder

1/2 teaspoon paprika

1/2 teaspoon salt

1/4 teaspoon black pepper

1/4 cup breadcrumbs

1 tablespoon chopped parsley for garnish

Directions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil.

Bring a large pot of water to a boil. Add the broccoli and cauliflower florets and cook for about 3 minutes until slightly tender but still crisp. Drain well and set aside.

In a skillet over medium heat, heat the olive oil. Add the chopped onion and cook for 4–5 minutes until softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.

In a large mixing bowl, combine the cottage cheese, sour cream, eggs, onion powder, garlic powder, paprika, salt, and black pepper. Mix until smooth.

Add the cooked chicken, broccoli, cauliflower, onion mixture, cheddar cheese, and half of the mozzarella cheese to the bowl. Stir everything together until evenly coated.

Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle the remaining mozzarella cheese over the top, followed by the breadcrumbs.

Bake uncovered for 30–35 minutes or until the casserole is bubbling and the top is golden brown.

Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with chopped parsley if desired.

Variations

For a spicier version, add a pinch of red pepper flakes or diced jalapeños to the mixture.

Swap cheddar cheese with Monterey Jack, Swiss, or gouda for a different flavor profile.

You can also use turkey instead of chicken for a lighter twist.

For added texture, stir in sliced mushrooms or spinach before baking.

If you prefer a lower-carb option, replace the breadcrumbs with crushed almonds or simply leave them out.

Storage/Reheating

If reheating from frozen, thaw overnight in the refrigerator before warming in the oven.
