Ingredients Overview

Here’s a closer look at the powerhouse ingredients that make this dish both delicious and nutritious:

Chicken Breast

• Boneless, skinless chicken breasts are lean and loaded with protein.

• Dice or shred cooked chicken for easy layering.

• Rotisserie chicken works great for convenience.

Zucchini

• A naturally low-calorie vegetable that adds moisture and texture.

• Slice into rounds or half-moons for even cooking.

• Salt and drain briefly if your zucchini is extra watery.

Eggs

• Act as a binder, helping hold the casserole together.

• Also add protein and richness.

Cottage Cheese

• High in casein protein, cottage cheese gives creaminess without extra fat.

• Adds a light tang and helps boost overall protein content.

Mozzarella Cheese

• Melts beautifully, creating that golden, bubbly topping.

• Use part-skim mozzarella for a lighter option.

Parmesan Cheese

• Adds a salty, umami kick to the mix.

• Helps brown the top and deepen flavor.

Herbs & Seasoning

• Garlic powder, onion powder, oregano, salt, and pepper are essential.

• Basil or thyme work well as additional herbs.

• Optional: A pinch of chili flakes for heat.

Optional Add-Ins

• Spinach or kale for extra greens.

• Cherry tomatoes for juiciness and color.

• Cooked quinoa for added fiber and complex carbs (if not low-carb focused).

Step-by-Step Instructions

Step 1: Prepare the Chicken

If using raw chicken, season lightly with salt and pepper, then bake or pan-cook until fully done. Dice or shred into small pieces. If using pre-cooked chicken, skip to the next step.

Tip: Use about 2½–3 cups of cooked, chopped chicken.

Step 2: Prepare the Zucchini

Slice zucchini into thin half-moons. Lightly salt and let sit in a colander for 10 minutes to release excess water. Pat dry with a clean towel.

This prevents the casserole from becoming watery as it bakes.

Step 3: Mix the Filling

In a large bowl, whisk together:

• 3 eggs

• 1 cup cottage cheese

• 1 tsp garlic powder

• 1 tsp onion powder

• ½ tsp dried oregano

• ½ tsp salt

• ¼ tsp black pepper

Then fold in:

• Cooked chicken

• Sliced zucchini

• 1 cup shredded mozzarella

• Optional add-ins (e.g., spinach, tomatoes)

Step 4: Assemble and Bake

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or casserole pan.

Pour the mixture into the dish, spreading evenly. Sprinkle the top with:

• ½ cup mozzarella

• ¼ cup grated parmesan

Bake uncovered for 35–40 minutes, or until the top is golden and the center is set. Let rest for 10 minutes before slicing.

Tips, Variations & Substitutions

• Zucchini overload? Add half zucchini, half yellow squash for color and texture variation.

• Add cooked mushrooms or onions for a more savory flavor.

• For dairy-free, replace cheese with plant-based options and add a spoonful of nutritional yeast for flavor.

• Swap cottage cheese with ricotta if preferred.

• Want more carbs? Stir in a cup of cooked brown rice or quinoa before baking.

Serving Ideas & Occasions

This casserole is perfect for:

• Meal prep: Portion into containers for a week’s worth of lunches.

It keeps well for 4–5 days in an airtight container. Reheat in the microwave or oven. It’s great for meal prep!
