Ingredients for Baked Egg Casserole

• Bacon: Adds salty savory flavor to the dish.
• Bell Peppers: A little crunch and mild flavor to add depth and variety to the dish which helps you feel more satisfied.
• Eggs: A lot of eggs are needed! We prefer to use large eggs.
• Milk: Creates a softer egg.
• Seasonings: Add flavor with minimal effort.
• Sharp Cheddar Cheese: Sharp cheese adds a lot more flavor to the dish compared to a mild variety.

How to Make Baked Egg Casserole

1. Grease a casserole dish so the eggs don’t stick.
2. Cook the bacon until crispy.
3. Sauté the peppers and add the onions and seasonings.
4. Chop the bacon.
5. Beat the eggs and milk.
6. Stir in the remaining bacon, peppers mix and cheese into the egg mixture, reserving a small amount of cheese to sprinkle on top.
7. Pour into the prepared baking dish and add remaining cheese, and bake until a knife inserted into the middle comes out clean, about 30-40 minutes.
