Ingredients
- 2 Tbsp unsalted butter, divided, plus more for greasing
- 8 large eggs
- 3/4 cup whole milk
- Kosher salt
- Freshly ground black pepper
- 4 oz Gruyère, shredded (about 1 cup), divided
- 4 oz sharp cheddar, shredded (about 1 cup), divided
- 9 Tbsp neutral oil, divided
- 20 oz breakfast sausage, casings removed
- 1/2 yellow onion, finely chopped
- 2 (16-oz) packages frozen shredded hash browns, divided
- Sliced chives, for serving
- Pure maple syrup and/or hot sauce, for serving
Instructions
- Preheat oven to 375°F (190°C). Grease a 13×9-inch baking dish with butter.
- In a large bowl, whisk eggs and milk. Season with salt and pepper, then mix in half the Gruyère and half the cheddar. Set aside.
- Heat 1 Tbsp oil in a medium skillet over medium heat. Add sausage, crumble, and cook until browned and fully cooked. Transfer to a bowl.
- In the same skillet, cook the chopped onion over medium-low heat until translucent. Add to the sausage and let cool.
- In a large skillet, heat 4 Tbsp oil and 1 Tbsp butter over medium heat. Add one package of hash browns in an even layer. Cook 6 minutes until golden, flip, season, and cook until crisp. Spread this batch into the bottom of the baking dish.
- Repeat with remaining oil, butter, and second package of hash browns. Leave the second batch in the skillet once crisp.
- Spread sausage and onion mixture evenly over the first layer of hash browns. Pour egg mixture over the top.
- Place the second hash brown layer over the eggs, then finish with remaining Gruyère and cheddar.
- Bake 25–30 minutes, until cheese is melted and golden. Top with chives and serve with maple syrup or hot sauce.
Notes
- Add sautéed bell peppers or mushrooms for extra vegetables.
- Use hot sausage or crushed red pepper for a spicier version.
- Swap Gruyère for mozzarella or Swiss for different flavors.
- Add smoked paprika for a light smoky note.
