How to Make Ground Beef and Zucchini Casserole
Phase 1 – Prep
STEP 1. Preheat oven. Set oven to 350°F (175°C).
STEP 2. Prep zucchini. Slice zucchini into rounds. Place in a colander, sprinkle with salt, and let sit for 10 minutes.
STEP 3. Dry zucchini. Pat zucchini slices dry with paper towels to remove excess water.
Phase 2 – Cook
STEP 4. Cook onion. Heat oil in a large skillet over medium heat. Add onion and sauté until softened and lightly golden, about 5 minutes.
STEP 5. Add garlic. Stir in garlic and cook for 1 minute until fragrant.
STEP 6. Brown beef. Add ground beef, breaking it up with a spoon. Cook until fully browned with no pink remaining, about 5–7 minutes. Drain extra fat if needed.
STEP 7. Season & make sauce. Stir in salt, pepper, garlic powder, and Italian seasoning. Add crushed tomatoes, tomato paste, broth (or water), cottage cheese, and parmesan. Mix well and simmer for 2–3 minutes.
STEP 8. Mix in half the zucchini. Stir half of the zucchini slices into the beef and sauce mixture.
STEP 9. Assemble casserole. Lightly grease a 9×13 casserole dish with oil or cooking spray, then spread the beef-zucchini mixture evenly into the greased baking dish. Arrange the remaining zucchini slices evenly on top. Leave some sauce showing through.
STEP 10. First bake. Bake for 15 minutes.
STEP 11. Add cheese. Remove from oven, sprinkle mozzarella evenly over the top.
STEP 12. Finish baking. Bake for another 10–15 minutes, until cheese is melted and lightly browned.
STEP 13. Rest & serve. Let rest for 5–10 minutes before slicing. Garnish with fresh basil and serve warm.
Why This Recipe Works
This casserole achieves an ideal balance of flavors and textures. The ground beef forms a hearty base, while the zucchini layers in moisture and nutrition. The creamy tomato sauce binds the components together, giving each bite a satisfying flavor.
The combination of Parmesan and mozzarella provides both depth and melty richness, while the baking creates an appealing golden top. The slow layering of flavors and textures—from the savory beef to the bright zucchini and creamy sauce—ensures that every forkful is bursting with deliciousness.
Pro Tips
For the best results, be sure to pat the zucchini dry after salting to prevent excess moisture in the casserole. Use lean ground beef to keep the dish light while still packing a protein punch. If you’re short on time, consider prepping the sauce ahead of time or using leftover cooked beef for a quick assembly later. Experiment with the seasoning to suit your personal taste, and don’t shy away from trying different cheeses to find your ideal blend!
