Recipe Instructions

Step 1

Preheat the oven to 450 degrees F (230 degrees C).

Step 2

Prick potatoes several times with a fork and place onto a baking sheet.

Step 3

Bake in the preheated oven until potatoes are soft, 50 to 60 minutes. Remove potatoes from the oven and let cool until safe to handle, at least 15 minutes.

Step 4

Reduce oven temperature to 350 degrees F (175 degrees C). Spray a 9x13-inch baking dish with cooking spray.

Step 5

Heat a large skillet over medium-high heat. Cook and stir sausage in the hot skillet until browned and crumbly, 5 to 7 minutes. Transfer sausage to a medium bowl. Sauté onion in the same skillet until translucent, about 5 minutes. Transfer onion to cooked sausage in the bowl.

Step 6

Add eggs, 1/2 of the Cheddar cheese, milk, salt, and pepper to sausage-onion mixture in the bowl. Mix until well combined.

Step 7

Grate potatoes and add to egg mixture in the bowl. Stir until evenly incorporated, then pour into the prepared dish. Sprinkle remaining Cheddar cheese on top.

Step 8

Bake in the preheated oven until heated through and cheese is melted and bubbly, about 35 minutes.
