Gather all ingredients.
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.
Mix eggs, cheese, bacon/sausage, red bell pepper, broccoli, milk, garlic, salt, and black pepper together in a bowl until well-combined; pour into the prepared baking dish.
Bake in the preheated oven until eggs are set, about 20 to 25 minutes.
