🥚 What is an Egg Casserole Bake?

An egg casserole bake is a baked dish made by combining beaten eggs with vegetables, meats, and/or cheese, then baking until firm and golden. Think of it as a cross between a frittata and a crustless quiche — but even easier. It’s a popular healthy breakfast casserole that can be customized to suit any palate or dietary need.

Unlike classic brunch dishes like Eggs Benedict, which require poaching eggs and emulsifying sauces, this recipe is fuss-free and foolproof, making it a great option for cooks of all skill levels.

🛒 Ingredients You’ll Need

This recipe calls for wholesome, accessible ingredients that deliver on both nutrition and taste. Here’s the base version:

✨ Base Ingredients:

• 10 large eggs
• 1 cup milk (or dairy-free milk like almond or oat)
• 1 cup shredded cheddar cheese (or mozzarella, feta, or dairy-free cheese)
• 1 red bell pepper, diced
• 1 cup fresh baby spinach, chopped
• ½ cup red onion, finely chopped
• 1 cup cooked turkey sausage or chicken sausage, sliced or crumbled (optional)
• ½ cup cherry tomatoes, halved
• ½ tsp garlic powder
• ½ tsp smoked paprika
• Salt and pepper, to taste
• Cooking spray or olive oil for greasing the dish

🧑‍🍳 Step-by-Step Instructions

Step 1: Prep Your Oven & Pan

Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with olive oil or non-stick cooking spray.

Step 2: Sauté the Veggies

In a skillet over medium heat, add a teaspoon of olive oil and sauté the onions and bell pepper for about 4–5 minutes. Add spinach last and cook just until wilted. If using sausage or mushrooms, toss them in to heat through.

Step 3: Mix the Egg Base

In a large bowl, whisk together eggs, milk, garlic powder, paprika, salt, and pepper. Stir in half the shredded cheese.

Step 4: Assemble

Pour the sautéed vegetables and sausage into the casserole dish. Spread them out evenly. Pour the egg mixture over the top, then sprinkle the remaining cheese and cherry tomatoes across the surface.

Step 5: Bake

Place in the oven and bake for 35–40 minutes, or until the center is set and a knife inserted comes out clean.

Step 6: Cool and Serve

Let it rest for 5–10 minutes before slicing. Garnish with chopped parsley, green onions, or basil if desired.
