Ingredients
- 1 pound ground beef
- 2 medium zucchini, sliced into thin rounds
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 cup sour cream
- 1 cup shredded mozzarella cheese
- 1/2 cup grated cheddar cheese
- 1/2 cup cream cheese, softened
- 1 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon olive oil
Step By Step Instructions
- Preheat your oven to 375 F. Lightly grease a medium baking dish with oil or cooking spray.
- Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook for 2 to 3 minutes until soft.
- Add the garlic and cook for 30 seconds until fragrant.
- Add the ground beef. Break it apart with a spoon and cook until browned. Drain any extra grease.
- Stir in salt, pepper, and Italian seasoning. Turn off the heat.
- In a bowl, mix sour cream and cream cheese until smooth and creamy.
- Layer half of the zucchini slices in the baking dish. Spread half of the beef mixture on top.
- Spoon half of the cream mixture over the beef. Spread gently to cover.
- Repeat the layers with the remaining zucchini, beef, and cream mixture.
- Sprinkle mozzarella and cheddar cheese evenly over the top.
- Bake uncovered for 25 to 30 minutes until the cheese is melted and golden.
- Let the casserole rest for 5 to 10 minutes before serving. This helps it set and makes slicing easier.
Common Mistakes To Avoid

Using thick zucchini slices: Thin slices cook faster and turn tender. Thick slices may stay firm and watery.
Not draining the beef: Extra grease can make the casserole oily. Always drain well after browning.
Skipping the rest time: Letting it rest helps the creamy layers firm up. If you cut too soon, it may fall apart.
Tips For Success
If your zucchini seems very watery, sprinkle it lightly with salt and let it sit for 10 minutes. Pat dry with paper towels before layering.
For more flavor, add a pinch of paprika or red pepper flakes to the beef. It gives a gentle kick without overpowering the dish.
