Ingredients for Zucchini Pizza Casserole
Here’s what you’ll need to make this delicious Zucchini Pizza Casserole:
4 cups shredded unpeeled zucchini – Choose firm, fresh zucchini for the best texture. Shredding allows the zucchini to cook down perfectly.
1/2 teaspoon salt – This little pinch helps draw out excess moisture from the zucchini.
2 large eggs – These bind the ingredients together and add a richness to the dish.
1/2 cup grated Parmesan cheese – For that nutty, salty flavor that complements the other cheeses and ingredients beautifully.
2 cups shredded part-skim mozzarella cheese, divided – This provides gooey, melty goodness. Dividing it gives the dish a cheesy surprise.
1 cup shredded cheddar cheese, divided – Adds a sharp flavor that pairs wonderfully with the other cheeses.
1 pound ground beef – For the traditional pizza essence, choose lean ground beef for a healthier option.
1/2 cup chopped onion – Adds sweetness and depth to the dish, enhancing the overall flavor profile.
1 can (15 ounces) Italian tomato sauce – Use your favorite brand for an authentic taste, adding moisture and zing to the casserole.
1 medium green or sweet red pepper, chopped – Adds a splash of color and a subtle crunch that balances the richness of the cheese.
How to Make Zucchini Pizza Casserole
Follow these simple steps to prepare this delicious Zucchini Pizza Casserole:
Step 1: Prepare the Zucchini
Preheat your oven to 400°F (200°C). Place the shredded zucchini in a colander and sprinkle with salt. Allow it to sit for about 10 minutes to draw out excess moisture. Once time is up, give it a good squeeze to drain any liquid; you want your casserole to be hearty, not soggy.
Step 2: Combine Ingredients for the Base
In a large mixing bowl, combine the drained zucchini with the eggs, grated Parmesan cheese, and half of the mozzarella and cheddar cheeses. Mix well until everything is evenly coated, then press this mixture into a greased 13×9-inch baking dish, creating an even layer. Bake this wonderful base for 20 minutes, letting it firm up beautifully.
Step 3: Cook the Beef
While the base is baking, take a deep breath and get ready for the next delicious step. In a large saucepan over medium heat, cook the ground beef with the chopped onion until the beef is no longer pink. Use a wooden spoon to break the meat into crumbles. Once fully cooked, drain any excess fat and stir in the tomato sauce. Let this savory mixture simmer for a few moments to blend the flavors.
Step 4: Assemble the Casserole
Once the zucchini base is done, carefully remove it from the oven. Pour the meat and sauce mixture evenly over the zucchini layer. Now, sprinkle the remaining mozzarella and cheddar cheese on top, followed by the chopped green or red pepper for that fresh finish.
Step 5: Bake to Perfection
Return the assembled casserole to the oven and bake for an additional 20 minutes, or until the cheese is melted and bubbly. Keep a close eye on it; your kitchen will soon fill with an irresistible aroma.
Step 6: Serve and Enjoy
Remove the casserole from the oven and let it cool for a few minutes before cutting into squares. Serve warm and savor the warm, melty goodness topped with fresh herbs if you’d like. This dish is perfect for plating and sharing at a family gathering or just curling up in front of a movie with loved ones.
