Ingredients
1 lb ground beef
2 medium zucchinis, sliced into thin rounds
1 small onion, diced
2 cloves garlic, minced
1 tsp Italian seasoning
½ tsp paprika
Salt and pepper, to taste
1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
2 eggs
½ cup milk
1 tbsp olive oil
Optional: 2 tbsp grated Parmesan
Fresh parsley for garnish
Instructions
Step 1: Preheat & Prep
Preheat your oven to 375°F (190°C)
Grease a casserole dish with olive oil or non-stick spray
Step 2: Cook the Ground Beef Mixture
In a large skillet, heat olive oil over medium heat
Add diced onion and cook for 2–3 minutes until softened
Add garlic and cook for another 30 seconds
Add ground beef, breaking it up with a spoon
Cook until browned, about 6–8 minutes
Season with Italian herbs, paprika, salt, and pepper
Drain excess fat if needed
Step 3: Prepare the Zucchini
Slice zucchini into ¼-inch rounds
Lightly salt and pat dry with a paper towel to reduce moisture
Step 4: Assemble the Casserole
Spread half of the zucchini slices in the bottom of the casserole dish
Spoon the cooked beef mixture evenly over the zucchini
Add the remaining zucchini on top
In a small bowl, whisk together eggs and milk
Pour egg mixture evenly over the casserole
Top with cheddar, mozzarella, and optional Parmesan
Step 5: Bake
Bake for 30–35 minutes, or until the top is golden and bubbly
Let cool for 5–10 minutes before slicing
Step 6: Garnish & Serve
Sprinkle with chopped fresh parsley and serve warm
Pair with a green salad or crusty bread if desired
Notes
Pat Zucchini Dry – This keeps the casserole from becoming watery
Use Full-Fat Cheese – Melts better and adds rich flavor
Add Extra Veggies – Mushrooms, bell peppers, or spinach work great
Make It Spicy – Add red pepper flakes or a pinch of cayenne to the beef
Double for a Crowd – Easily scaled up for meal prep or potlucks
