- 1 (15 ounce) can tomato sauce or marinara
Instructions
- Preheat oven to 400°F (200°C).
- Place shredded zucchini in a colander and sprinkle with 1/2 teaspoon salt. Let stand for 10 minutes to draw out moisture.

- Bake the zucchini crust for 20 minutes.
- While the zucchini bakes, cook ground beef and chopped onion in a large saucepan over medium heat until the meat is no longer pink.
- Add minced garlic to the beef mixture and cook for one minute more. Drain any excess fat.
- Stir in the tomato sauce with the beef mixture and spoon it over the baked zucchini crust.
- Sprinkle the remaining mozzarella and cheddar cheeses over the top.
- Bake for an additional 10 minutes, or until the cheese is melted and bubbly.
- Let the casserole rest for a few minutes before serving.
Notes
– For a richer flavor, brown the ground beef until deeply caramelized before adding the onions and garlic.
– The internal temperature for ground beef should reach 160°F (71°C) to ensure it is fully cooked before mixing with the sauce.
– Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 300°F (150°C) until warmed through. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The key technique in making a successful zucchini casserole lies in properly managing moisture. Zucchini has a high water content, which can lead to a soggy casserole if not addressed. Shredding the zucchini and salting it allows for moisture extraction through osmosis. After salting, let the zucchini sit for about 10-15 minutes, then squeeze out the excess liquid using a clean kitchen towel. This step helps maintain the integrity of the casserole, ensuring it is not watery and the flavors concentrate.
Troubleshooting
- Problem: Casserole is too watery.
Fix: Ensure you salt and drain the zucchini properly before mixing it with the other ingredients. - Problem: Casserole lacks flavor.
Fix: Increase the amount of seasoning in the ground beef mixture, or add herbs like oregano or basil to enhance the flavor profile. - Problem: Cheese is not melting properly.
Fix: Make sure the casserole is baked at the right temperature (around 350°F) and for the appropriate time to allow the cheese to melt and bubble. - Problem: Casserole is overcooked.
Fix: Keep an eye on the cooking time; check for doneness a few minutes before the suggested time to prevent overcooking.
Substitutions
- Ground beef: Substitute with ground turkey or chicken for a leaner option without sacrificing texture.
- Parmesan cheese: Use Pecorino Romano for a sharper flavor that complements the other cheeses.
- Tomato sauce: Swap with homemade tomato sauce or a spicy marinara for added depth and flavor.
- Cheddar cheese: Replace with Gouda for a smoky flavor that pairs well with the zucchini and beef.
