Step‑by‑Step Instructions for High Protein Veggie Lasagna
Step 1: Preheat the Oven
Begin your culinary journey by preheating the oven to 375°F (190°C). This important first step ensures that the High Protein Veggie Lasagna bakes evenly, allowing the flavors to meld beautifully as it cooks. While the oven warms up, gather your baking dish and other ingredients, setting the stage for a delightful assembly.
Step 2: Sauté the Vegetables
Heat a splash of olive oil in a skillet over medium heat, then add your sliced bell peppers and fresh spinach. Sauté for about 5–7 minutes, stirring occasionally until the veggies are tender and vibrant. This process not only enhances their natural sweetness but also infuses your High Protein Veggie Lasagna with extra flavor. Once cooked, transfer them to a bowl and set aside.
Step 3: Prepare the Cheese Mixture
In a separate bowl, combine the ricotta cheese, egg, garlic powder, Italian seasoning, salt, pepper, and half of the Parmesan cheese. Mix until the mixture is smooth and creamy, creating a luscious filling for your lasagna. This delightful cheese blend is essential for the rich, comforting layers of your High Protein Veggie Lasagna, so don’t rush this step!
Step 4: Assemble the Lasagna
Grab your baking dish and start layering! Spread a thin layer of the ricotta mixture on the bottom, followed by a layer of zucchini slices or traditional noodles. Next, add the sautéed bell peppers and spinach. Then, dollop more ricotta mixture on top and sprinkle with mozzarella. Repeat these layers until all ingredients are used, finishing with a final layer of zucchini and the remaining cheeses on top.
Step 5: Bake the Lasagna
Cover the assembled High Protein Veggie Lasagna with aluminum foil, placing it in the preheated oven. Bake for 25 minutes to allow the flavors to meld while keeping the moisture intact. Carefully remove the foil and continue baking for an additional 10–15 minutes, until the cheese is golden and bubbly. You’ll know it’s done when you see a deliciously browned top.
Step 6: Let It Rest
After baking, remove the lasagna from the oven and allow it to sit for about 10 minutes before slicing. This resting period helps the layers to set, ensuring clean cuts and a beautiful presentation. As you wait, the aromas will fill your kitchen, igniting excitement for the heartwarming meal ahead!
Step 7: Serve and Enjoy
Slice your High Protein Veggie Lasagna into portions and serve warm. You might like to garnish each slice with fresh herbs for a pop of color and flavor. This comforting dish pairs wonderfully with a fresh salad or some crusty garlic bread, making it a satisfying meal for family gatherings or cozy nights in.

How to Store and Freeze High Protein Veggie Lasagna

Make Ahead Options
