What Kind of Zucchini Should I Use?

For best results, use fresh, medium-sized zucchini. They have tender skins and fewer seeds, making them ideal for shredding or slicing into ribbons. Overgrown zucchinis tend to be more watery and can lead to a soggy casserole, so stick to firm and slender ones when possible.

Ingredients for the Shredded Zucchini Casserole

Every ingredient in this casserole plays a part in building comfort, flavor, and balance. Here’s why each one matters:

Zucchini: The star of the dish. It acts as a lighter alternative to pasta or potatoes while adding moisture and nutrients.
Ground beef: Adds heartiness and protein to make this a full, satisfying meal.
Onion: Enhances the savory depth of the meat mixture.
Garlic: Infuses aromatic flavor into the entire casserole.
Cheddar cheese: Melts to create a gooey, golden topping with bold flavor.
Mozzarella cheese: Offers stretchy meltiness and balances the cheddar’s sharpness.
Eggs: Help bind the layers together and create a custardy texture.
Sour cream: Adds richness and a touch of tang.
Salt and pepper: Essential seasonings to enhance all the other flavors.

How To Make the Shredded Zucchini Casserole

Step 1: Prep the Zucchini

Shred or thinly slice your zucchini, sprinkle with salt, and let it sit for 10 minutes. Then press out the excess water with a clean towel to avoid a soggy bake.

Step 2: Cook the Meat Mixture

In a skillet, brown the ground beef with chopped onion and garlic until fully cooked and fragrant. Season with salt and pepper.

Step 3: Create the Creamy Egg Layer

In a bowl, whisk together eggs and sour cream. This will serve as your binding agent and create a soft, custard-like consistency throughout the casserole.

Step 4: Assemble the Layers

In a greased baking dish, start with a layer of zucchini, followed by the meat mixture, a sprinkle of both cheeses, and a bit of the egg mixture. Repeat until all ingredients are used, finishing with cheese on top.

Step 5: Bake to Perfection

Bake in a preheated oven at 375°F (190°C) for about 25-30 minutes, or until the top is bubbly and golden brown.
