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 essential step ensures that your High Protein Veggie Lasagna bakes evenly, giving you that perfect golden cheese top. While your oven heats, take a moment to gather all your ingredients and equipment, making the cooking process smooth and enjoyable.
Step 2: Prepare the Vegetables
In a large skillet, drizzle a tablespoon of olive oil and heat over medium heat. Add the chopped assorted bell peppers and sauté for about 5 minutes, or until they begin to soften. Stir in the baby spinach, cooking for an additional 2-3 minutes until wilted. Once done, set the vegetables aside to cool slightly while you move on to the cheese filling.
Step 3: Mix the Cheese Filling
In a mixing bowl, combine the ricotta cheese, egg, garlic powder, Italian seasoning, salt, pepper, and grated Parmesan. Use a fork or spatula to blend the mixture until it achieves a creamy consistency. This creamy cheese mixture is what will bring your High Protein Veggie Lasagna to life, so take your time to ensure it’s well combined for even distribution in the layers.
Step 4: Layer the Lasagna
Grab a 9×13 inch baking dish and start by spreading a thin layer of the ricotta mixture on the bottom. Next, add a layer of thinly sliced zucchini as your noodle substitute. Follow this with the sautéed bell peppers and spinach, dollops of the cheese filling, and a sprinkle of mozzarella. Repeat these layers until all ingredients are used, finishing with a layer of mozzarella on top for that irresistible gooey finish.
Step 5: Bake Covered
Cover your baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes; this steams the lasagna, allowing flavors to meld together beautifully. Keep an eye on it, as the aroma of the High Protein Veggie Lasagna will fill your kitchen and get everyone excited for dinner!
Step 6: Finish Baking
After 25 minutes, carefully remove the foil, making sure not to let it touch the cheesy top. Return the lasagna to the oven and bake uncovered for an additional 10-15 minutes, or until the cheese is bubbly and golden brown. This step adds a delightful crispness to the top, making each bite even more satisfying.
Step 7: Rest Before Serving
Once out of the oven, let your High Protein Veggie Lasagna rest for about 10 minutes. This resting time allows the layers to set, making it easier to slice neatly. If desired, garnish with fresh herbs for an added touch of flavor and color. Now, it’s time to serve and relish in the comforting goodness of your homemade creation!
