Step‑by‑Step Instructions for High Protein Veggie Lasagna

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This will ensure that your High Protein Veggie Lasagna bakes evenly. While the oven heats up, gather all your ingredients and equipment, such as a large baking dish and mixing bowls, to facilitate a smooth cooking process.

Step 2: Prepare the Vegetables
In a skillet over medium heat, add a splash of olive oil, then sauté the sliced bell peppers and fresh spinach for about 5 minutes or until softened. Keep stirring to prevent sticking and ensure even cooking. Once they become tender and vibrant, remove them from the heat and set aside to cool slightly.

Step 3: Mix the Cheese Filling
In a mixing bowl, blend together the ricotta cheese, whole egg, garlic powder, Italian seasoning, salt, and pepper. Use a spatula to mix until the combination is creamy and well-combined. This protein-rich filling will add delicious flavor to your High Protein Veggie Lasagna layers, so make sure it’s smooth and evenly mixed.

Step 4: Layer the Lasagna
Grab your prepared baking dish and start layering your ingredients. Begin with a generous dollop of the ricotta mixture on the bottom, followed by a layer of zucchini slices or high-protein lasagna sheets. Add a layer of the sautéed vegetables, then repeat the layering process with more ricotta mixture and mozzarella cheese. Continue layering until you finish with mozzarella and a sprinkle of parmesan on top.

Step 5: Bake the Lasagna
Cover your lasagna with aluminum foil to retain moisture and place it in the preheated oven. Bake for 25 minutes, allowing all the flavors to meld. After 25 minutes, carefully remove the foil and continue baking for an additional 10–15 minutes. This will give you that golden, bubbly cheese on top.

Step 6: Rest and Serve
Once the baking time is complete, take the High Protein Veggie Lasagna out of the oven, and let it rest for at least 10 minutes before slicing. This resting period allows the layers to set for clean cuts. For an added touch, garnish with fresh herbs before serving for an extra burst of flavor.
