Making the Sheet Pan Breakfast Bake is a seamless process when you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and grease a large baking sheet with non-stick spray or olive oil.
2. Cook Sausage: In a large skillet over medium heat, cook the crumbled sausage until browned, about 5-7 minutes. Drain excess fat and set aside.
3. Sauté Vegetables: In the same skillet, add the diced bell peppers and onions. Sauté until softened, approximately 3-4 minutes.
4. Whisk Eggs: In a large mixing bowl, whisk together the eggs and milk. Add garlic powder, onion powder, salt, and pepper, whisking until fully combined.
5. Combine Ingredients: Stir in the cooked sausage, sautéed vegetables, and half of the shredded cheese into the egg mixture.
6. Pour into Pan: Pour the mixture onto the prepared baking sheet, spreading it evenly across the surface.
7. Top with Cheese: Sprinkle the remaining cheese over the top of the egg mixture.
8. Bake: Place in the preheated oven and bake for 25-30 minutes or until the eggs are set and the top is golden brown.
9. Cool and Cut: Remove from the oven and let cool for a couple of minutes. Cut into squares or rectangles for serving.
10. Garnish: If desired, garnish with fresh herbs before serving.

By following these steps, your Sheet Pan Breakfast Bake will turn out beautifully with minimal effort!
