- Total Time: 1 hour
- Servings: 6
- Yield: 1 Casserole
- Dietary Type: Gluten-Free (Optional)
Ingredients
- 4 cups unpeeled shredded zucchini
- 1/2 teaspoon salt
- 2 eggs
- 1/2 cup grated Parmesan cheese
- 1 cup shredded cheddar cheese, divided (or to taste)
- 2 cups shredded mozzarella cheese, divided (or to taste)
- 1 lb ground beef
- 1-2 tablespoons minced fresh garlic
- Salt and pepper to taste
- 1 onion, chopped
- 1 (15 ounce) can Italian-style tomato sauce (tomato sauce, with 1/4 tsp. each, oregano and basil)
- 1 medium green pepper, seeded and chopped
Equipment Needed
- 13×9 inch baking pan
- Strainer
- Large skillet
- Cheese grater
- Mixing bowls
Instructions
- Preheat your oven to 400°F (200°C).
- Grease a 13×9 inch baking pan. This will prevent the casserole from sticking and make serving easier.
- Place the 4 cups of shredded zucchini in a strainer. Sprinkle with 1/2 teaspoon of salt. The salt will help draw out excess moisture from the zucchini.
- Let the zucchini drain for 10 minutes. This is a crucial step, don’t skip it!
- After 10 minutes, squeeze out as much moisture as possible from the zucchini. You can use your hands, a clean kitchen towel, or even a cheesecloth to do this. Removing excess moisture will prevent the casserole from being soggy.
- In a large mixing bowl, combine the squeezed zucchini with the 2 eggs, 1/2 cup of grated Parmesan cheese, and half of the shredded cheddar cheese and mozzarella cheese. Mix well to ensure everything is evenly distributed. Reserve the remaining cheddar and mozzarella for topping.
- Press the zucchini mixture evenly into the greased 13×9 inch baking pan. This will form the base of your casserole.
- Bake the zucchini base at 400°F (200°C) for 20 minutes. This will help it set and firm up before adding the toppings.
- While the zucchini base is baking, prepare the ground beef topping. In a large skillet, brown 1 lb of ground beef over medium-high heat. Add 1-2 tablespoons of minced fresh garlic and the chopped onion. Season with salt and pepper to taste.
- Cook until the ground beef is fully cooked and the onion is softened. Drain any excess fat from the skillet.
- Add the 15 ounce can of Italian-style tomato sauce to the cooked ground beef mixture. Stir well to combine.
- Once the zucchini base has baked for 20 minutes, remove it from the oven. Spoon the ground beef and tomato sauce mixture evenly over the baked zucchini mixture.
- Top the casserole with the remaining shredded cheddar cheese and shredded mozzarella cheese. Sprinkle the chopped green pepper over the cheese.
- Return the casserole to the oven and bake for another 20 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
- Remove from the oven and let cool slightly before serving. This will help the casserole set a bit and make it easier to cut.
Expert Tips & Tricks
- Squeezing the Zucchini: Don’t underestimate the importance of squeezing out the moisture from the zucchini. If you don’t, the casserole will be watery.
- Cheese Variations: Feel free to experiment with different types of cheese. Provolone, Monterey Jack, or even a blend of Italian cheeses would work well.
- Garlic Lovers: If you love garlic, don’t be shy about adding more! You can also add a pinch of garlic powder to the zucchini mixture for extra flavor.
- Spice it up!: If you like a little heat, add a pinch of red pepper flakes to the ground beef mixture.
- Make Ahead: You can assemble the casserole ahead of time and keep it in the fridge, covered, for up to 24 hours before baking. This is a great option if you’re short on time during the week. Just add a few minutes to the baking time.
- Browning the Beef: For deeper flavor, really brown the ground beef well. Letting it get a little crispy around the edges will add a wonderful depth to the casserole.
- Seasoning: Taste as you go! Make sure the zucchini base and the beef mixture are well-seasoned. A little extra salt, pepper, or Italian seasoning can make a big difference.
