Step‑by‑Step Instructions for High-Protein Vegetable Breakfast Bake
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grease a 9×13-inch baking dish with olive oil to prevent sticking. This step is crucial to ensuring your High-Protein Vegetable Breakfast Bake slides out easily once it’s baked, leading to beautiful, square slices that everyone will enjoy.
Step 2: Whisk the Eggs
In a large mixing bowl, whisk together the egg whites and whole eggs until the mixture is uniform and pale yellow, which should take about 2-3 minutes. This creates a light and fluffy base for your breakfast bake. The blend of egg whites and whole eggs is vital for a high-protein content while providing a deliciously rich flavor.
Step 3: Incorporate the Cheeses
Gradually stir in the cottage cheese and grated cheddar into the egg mixture, ensuring everything is thoroughly mixed. As you do this, the creamy texture of the cottage cheese will blend beautifully with the eggs, creating a well-rounded batter. This step enhances the moisture and flavor of your High-Protein Vegetable Breakfast Bake.
Step 4: Sauté the Vegetables
In a large skillet, heat a tablespoon of olive oil over medium heat. Add the diced red and green bell peppers, along with the chopped onion and broccoli florets. Sauté these vibrant vegetables for about 5 minutes, or until they begin to soften and become fragrant. This will bring out their natural flavors, adding a hearty quality to your bake.
Step 5: Add Spinach
Once the other vegetables are slightly tender, fold in the chopped spinach and cook until wilted, approximately 2 minutes. The spinach should be bright green and seamlessly blend with the sautéed vegetables. This addition not only boosts nutrition but also adds a lovely pop of color to your High-Protein Vegetable Breakfast Bake.
Step 6: Mix Everything Together
Combine the sautéed vegetable mixture with the egg and cheese blend in the large bowl. Sprinkle in the garlic powder, salt, and black pepper, then mix well until all ingredients are evenly distributed. This harmonious blend of flavors is essential for a deliciously satisfying breakfast bake, ensuring every bite is packed with goodness.
Step 7: Pour into Baking Dish
Carefully pour the combined mixture into your prepared baking dish, spreading it evenly with a spatula. Ensure the mixture is level for even cooking. This helps all portions of the High-Protein Vegetable Breakfast Bake to bake uniformly, resulting in a beautifully golden brown top across the entire dish.
Step 8: Bake to Perfection
Place the baking dish in your preheated oven and bake for 30–35 minutes. Keep an eye on it and look for the center to be set and the top to be a lovely golden brown. This crucial step guarantees that your breakfast bake is cooked through while retaining its fluffy texture.
Step 9: Cool and Serve
After baking, remove the dish from the oven and let it cool for a few minutes before slicing into squares. The waiting period helps the flavors to settle and enhances the presentation of your High-Protein Vegetable Breakfast Bake. Serve warm, and get ready to enjoy a healthy and hearty breakfast with your family!
