Line a 9x5-inch loaf pan with parchment paper, leaving an overhang on the sides, and lightly grease.
Layer a single hash brown patty, a slice of ham, and a slice of cheese alternating until the pan is full.
In a bowl, whisk eggs, milk, salt, and pepper, then pour evenly over the layers, keeping it inside the parchment.
Bake at 375 degrees F for 60 to 70 minutes, until golden and crisp on top.
Let cool 10 to 15 minutes. Then carefully lift it out using the parchment, sprinkle with green onions (if using), and slice to serve.
Notes
Note 1: Rectangular (or rectangle-shaped) hash brown patties can be found in the frozen aisle. Note 2: I love presliced ham found in the meat aisle. Make sure it isn’t sweetened. Note 3: Grab a package of presliced cheddar cheese, or have it sliced for you at the deli. Note 4: Use any type of milk except for skim. Unsweetened almond milk or lactose free milk will also work. Note 5: To keep this recipe low FODMAP, use only the tops of the green onions.
