Step 1: Prepare the Vegetables - Start by grating your zucchinis and carrot. Place them in a clean kitchen towel and squeeze out any excess moisture. This will prevent your casserole from becoming watery.
Step 2: Mix the Base - In a large mixing bowl, combine the grated zucchini, grated carrot, salt, black pepper, beaten egg, sour cream, and half of the shredded cheese. Mix until everything is well combined and creamy.
Step 3: Layer the Casserole - In your greased casserole dish, spread a layer of salsa at the bottom. Next, add half of the vegetable mixture, spreading it evenly. Top with a layer of salsa followed by a sprinkle of the remaining shredded cheese.
Step 4: Add More Layers - Repeat the layering process with the remaining vegetable mixture, another layer of salsa, and the last of the shredded cheese. This builds up flavor and texture in every bite!
Step 5: Bake - Preheat your oven to 375°F (190°C). Cover the casserole with aluminum foil and bake for about 30 minutes. After that, remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly.
Step 6: Cool and Serve - Once baked, let the casserole cool for about 10 minutes before slicing. This will help the layers hold together when serving. Enjoy your Lightened Up Vegetable Lasagna Casserole with a side salad or your favorite bread!
