Hearty Sausage, Egg, and Cheese Skillet

Heat 1 tablespoon of olive oil in a large oven-safe skillet over medium-high heat.

Add 1 pound of breakfast sausage to the skillet and cook, breaking it apart with a spoon, until browned and cooked through, about 5-7 minutes. Drain any excess grease.

Stir in 1/2 cup of chopped onion and cook until softened, about 3-4 minutes.

In a medium bowl, whisk together 6 large eggs, 1/4 cup of milk, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper until well combined.

Pour the egg mixture evenly over the sausage and onion in the skillet. Reduce heat to medium-low and cook for 3-5 minutes, stirring occasionally, until the eggs begin to set but are still slightly wet.

Sprinkle 1 cup of shredded cheddar cheese over the top of the eggs.

Transfer the skillet to a preheated oven at 350°F (175°C) and bake for 8-10 minutes, or until the eggs are fully set and the cheese is melted and bubbly.
