Veggie-Loaded Breakfast Casserole Ingredients

• Flavorful layers await!

For the Sautéed Vegetables

2 tablespoons oil – Aids in sautéing vegetables; olive oil or avocado oil are healthier alternatives.
8-10 mushrooms, sliced – Adds umami flavor and moisture; substitute with any preferred type (e.g., cremini, button).
2 teaspoons minced garlic – Enhances overall flavor; use garlic powder if fresh is unavailable.
½ red onion, diced – Provides sweetness and depth; yellow onion is a good substitute or omit for a milder flavor.
2 bell peppers, diced – Offers sweetness and color; feel free to use any variety (red, yellow, or green).
2 cups packed baby spinach, roughly chopped – Contributes nutrition and vibrant color; can swap with kale or Swiss chard.

For the Casserole Base

20 ounces shredded potatoes, thawed – Serves as the delightful base layer for texture; fresh grated potatoes work wonderfully too.
10 eggs – The binder for this casserole; for a lighter option, use egg whites or an egg replacement.
⅓ cup half and half or milk – Adds creaminess; can easily be replaced with non-dairy milk for a lighter feel.
¼ cup hot sauce (to taste) – Infuses spice and flavor; simply reduce or omit for a milder dish.
Salt and pepper – Essential for seasoning; adjust to your taste preferences.

For Topping

1 cup shredded cheese (e.g., cheddar, mozzarella) – Brings creaminess and adds another layer of flavor; consider dairy-free cheese as a substitute or omit for a lighter version.

Now you’re ready to embrace the flavors of this Veggie-Loaded Breakfast Casserole! Prepare each layer with love, and soon you’ll be sharing this dish with family and friends, bringing warmth and joy to your brunch table.

Step‑by‑Step Instructions for Veggie-Loaded Breakfast Casserole

Step 1: Sauté Vegetables
In a large skillet over medium heat, add 2 tablespoons of oil and let it warm for a moment. Toss in the sliced mushrooms and cook for about 4 minutes until they begin to brown. Then, add the minced garlic, diced red onion, and bell peppers. Sauté everything together for another 3-4 minutes, stirring until the veggies soften, and finally incorporate the baby spinach until it wilts.

Step 2: Prepare Baking Dish
Preheat your oven to 375°F. Generously spray a 9×13 inch baking dish with cooking spray to prevent sticking. Once the sautéed vegetables are ready, set them aside. Now, layer the thawed and shredded potatoes evenly across the bottom of the baking dish, pressing down gently to create a solid base for your Veggie-Loaded Breakfast Casserole.

Step 3: Combine Egg Mixture
In a large mixing bowl, crack 10 eggs and whisk them together until well beaten. Stir in ⅓ cup of half and half or milk, along with ¼ cup of hot sauce, salt, and pepper to taste. Mix these ingredients thoroughly until combined. This egg mixture will serve as the binder for your casserole, bringing all the rich flavors together.

Step 4: Layer Ingredients
Now it’s time to assemble the casserole! Start by spreading the sautéed vegetable mixture evenly over the layered hash browns. Carefully pour the egg mixture on top of the veggies and potatoes, ensuring even coverage. Finally, sprinkle 1 cup of your choice of shredded cheese across the top, allowing it to melt beautifully during baking.

Step 5: Bake
Place the baking dish in the preheated oven and bake uncovered for 45–50 minutes. Keep an eye on it—the Veggie-Loaded Breakfast Casserole will be ready when the top is golden and the eggs are fully set. To check for doneness, insert a knife in the center; it should come out clean.

Step 6: Cool and Serve
Once baked to perfection, remove the casserole from the oven and let it cool for about 10 minutes before slicing. This cooling time helps the layers set, making it easier to serve. Use a spatula for neat slices, and prepare to share this delightful dish with your family and friends!
