How to Make Ground Beef Zucchini Casserole
Step 1: Prepare the Zucchini

Step 3: Assemble the Casserole

- In an 8×8 baking dish, spread half of the ground beef mixture evenly across the base.
- Layer half of the zucchini slices over the beef mixture followed by half of the shredded mozzarella cheese.
- Repeat layering with remaining beef mixture, zucchini slices, and mozzarella cheese on top.
Step 4: Bake and Serve
