Veggie-Loaded Breakfast Casserole Ingredients For the Base: • Oil – Adds moisture and aids in frying veggies; can substitute with any neutral cooking oil. • Shredded Potatoes (20 ounces, thawed) – Forms the base and provides heartiness; frozen hash browns are ideal. For the Veggies: • Mushrooms (8-10, sliced) – Provide umami flavor and texture; any type can be used. • Garlic (2 teaspoons, minced or pressed) – Enhances flavor with aromatic notes; fresh garlic is preferable. • Red Onion (½, diced) – Adds sweetness and color; substitute with yellow or white onion if unavailable. • Bell Peppers (2, diced) – Contributes a crunchy texture and mild sweetness; use mixed colors for a vibrant presentation. • Baby Spinach (2 cups, packed, roughly chopped) – A nutrient-rich addition; can substitute with kale or Swiss chard. For the Binding: • Eggs (10) – Binds ingredients together for a custard-like texture; use large eggs for best results. • Half and Half (⅓ cup) or Milk – Adds creaminess; can substitute with non-dairy milk alternatives. • Hot Sauce (¼ cup, to taste) – Adds spice and flavor depth; reduce or omit for a milder dish. For the Flavor: • Salt and Pepper – Enhances seasoning; adjust according to taste. • Shredded Cheese (1 cup) – Provides creaminess and flavor; consider using cheddar, mozzarella, or pepper jack for your Veggie-Loaded Breakfast Casserole. Step‑by‑Step Instructions for Veggie-Loaded Breakfast Casserole Step 1: Prep Veggies In a large skillet over medium heat, add a splash of oil and sauté sliced mushrooms until they become tender and golden, about 4 minutes. Then, toss in minced garlic and diced red onion, stirring for an additional 2 minutes until fragrant. Remove the mixture from the heat and set it aside to cool slightly. Step 2: Sauté Peppers and Spinach Wipe down the skillet and drizzle in a little more oil if needed, then increase the heat to medium-high. Add the diced bell peppers and sauté for 1 minute until just tender, then fold in the chopped baby spinach until wilted, which should take about 2 minutes. Set the vibrant mixture aside with the other cooked veggies. Step 3: Assemble Casserole Preheat your oven to 375°F (190°C) and spray a 9×13-inch baking dish with nonstick cooking spray. Press the thawed shredded potatoes evenly into the bottom of the dish, forming a solid base for the Veggie-Loaded Breakfast Casserole. Ensure they cover the surface without any gaps for a perfectly baked crate. Step 4: Layer Ingredients Spread the sautéed mushroom and onion mixture over the layer of hash browns. In a separate bowl, whisk together the eggs, half and half, hot sauce, salt, and pepper. Pour this creamy egg mixture evenly over the veggies, ensuring all are coated and integrated, creating a luscious custard-like foundation. Step 5: Add Cheese Generously sprinkle the shredded cheese of your choice over the entire top surface of the casserole. This will help create a richly melty topping as the casserole bakes. Feel free to use a blend of cheeses for added flavor and texture to enhance your Veggie-Loaded Breakfast Casserole. Step 6: Bake Place the casserole in the preheated oven and bake uncovered for 45-50 minutes. You’ll know it’s done when the top is golden brown and the edges are bubbly. Allow the casserole to cool for about 10 minutes before cutting into squares, as this resting time will help it set for easier servings.
