Breakfast Casserole Vegetarian Recipe

The texture of the casserole is rich yet fluffy, with a slight crunch from the vegetables and a creamy base from the eggs and cheese. The seasoning brings everything together with a burst of flavor, and you can make it as mild or as bold as your palate desires.
Here’s How To Make It
Ingredients Needed
To create this vegetarian breakfast casserole, you’ll need a variety of basic ingredients, but don’t worry-nothing too complicated here. Here’s the list:
- Eggs: 8 large eggs will serve as the base. They provide structure, fluffiness, and protein.
- Milk: 1 cup (or dairy-free substitute, like almond or oat milk) to create a creamy texture in the eggs.
- Cheese: 1 ½ cups of shredded cheese (sharp cheddar, mozzarella, or a combination). You’ll want something that melts well.
- Potatoes: 2 medium-sized potatoes, peeled and diced. They add a hearty, filling component and soak up all the delicious flavors.
- Vegetables: You’ll need about 2 cups of diced vegetables. A mix of onions, bell peppers, spinach, mushrooms, and zucchini works beautifully.
- Garlic: 2 cloves of garlic, minced, to add that rich, savory depth to your casserole.
- Olive oil: 1 tablespoon to sauté your vegetables and prevent sticking.
- Spices: Salt (1 tsp), black pepper (½ tsp), dried oregano (1 tsp), and paprika (½ tsp). You can adjust these to taste.
- Fresh herbs (optional): A handful of chopped fresh parsley, basil, or chives for garnish or extra flavor.
You can add extras like sun-dried tomatoes, olives, or even a bit of hot sauce to really kick it up a notch!
Cooking Instructions
- Preheat the oven: Set it to 375°F (190°C) and grease a 9×13 baking dish with a bit of oil or cooking spray.
- Prepare the potatoes: In a medium skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced potatoes and sauté them until they’re golden brown and slightly crispy, about 10-12 minutes. Season with a pinch of salt and pepper.
- Cook the vegetables: In the same skillet, add the garlic and cook for 1 minute until fragrant. Then, toss in your mixed veggies (onions, bell peppers, mushrooms, zucchini). Sauté until they’re soft and any excess moisture has evaporated-about 5-7 minutes. Add spinach towards the end and cook until wilted.
- Assemble the casserole: Spread the sautéed potatoes and veggies evenly in the bottom of your prepared baking dish.
- Whisk the eggs: In a large bowl, beat the eggs with milk, salt, pepper, oregano, and paprika until fully combined. Pour this mixture over the veggies in the casserole dish.
- Add cheese: Sprinkle the shredded cheese evenly on top.
- Bake: Place the casserole in the oven and bake for 30-35 minutes or until the eggs are set and the top is golden brown.
- Cool and serve: Allow the casserole to cool for a few minutes before slicing it into squares. Garnish with fresh herbs if desired.
Ingredient Science Spotlight
Each ingredient in this casserole plays a specific role in contributing to the texture, flavor, and overall success of the dish. Here’s the science behind some of the key ingredients:
- Eggs: Eggs are the backbone of this casserole. They provide structure through their proteins, which coagulate when heated, creating a firm, yet soft texture. The fats in the egg yolks add richness and flavor, while the egg whites contribute to the fluffiness.
- Milk: Milk, especially full-fat milk, helps create a creamy, smooth texture in the egg mixture. The proteins in the milk combine with the eggs to provide a custard-like consistency.
- Potatoes: Potatoes add starch, which thickens the casserole and helps bind everything together. They also provide a satisfying, hearty component to the dish.
- Cheese: Cheese melts and binds the casserole together, adding both flavor and texture. It also helps in browning the top, giving it that appealing golden crust.
- Vegetables: Vegetables like spinach and mushrooms are high in water content, which helps balance the richness of the eggs and cheese. They also add fiber and micronutrients, making the dish healthier.
Expert Tips
- Make it ahead: This casserole can be assembled the night before and stored in the fridge. Just pop it in the oven the next morning for a quick breakfast.
- Use a variety of veggies: Don’t be afraid to experiment with different veggies! Broccoli, asparagus, or even sweet potatoes work beautifully in this casserole.
- Add extra flavor: Spice it up with chili flakes, hot sauce, or some Dijon mustard in the egg mixture. For extra richness, try adding a dollop of sour cream or Greek yogurt on top when serving.
- Go dairy-free: If you’re avoiding dairy, simply swap the cheese for a plant-based variety and use almond or oat milk. The texture will still be amazing.
- Use leftovers: If you have leftover roasted vegetables, throw them into the casserole mix for a quick and easy meal!
Recipe Variations
- Vegan Version: Replace the eggs with a tofu scramble or chickpea flour mixture. Use non-dairy milk and vegan cheese to make this dish plant-based.
- Muffin Cup Casseroles: For an individual portion, you can make these in muffin tins. Adjust cooking time to 20-25 minutes.
- Breakfast Burrito Style: Add cooked quinoa or rice to the mix, along with black beans, and top it with avocado after baking. Serve wrapped in a tortilla for a fun twist.
- Southwestern Style: Add black beans, corn, jalapeños, and a bit of cumin to the veggie mix for a Tex-Mex inspired casserole.
- Gluten-Free: This recipe is naturally gluten-free! Just be mindful of any pre-packaged items you use (like cheese or dairy alternatives).
