How to Make Hashbrown Breakfast Casserole
Step 1: Prepare the Hashbrowns
Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil. Spread the frozen hashbrowns evenly in the dish. Bake for 10 minutes to crisp them up slightly.
Step 2: Cook the Sausage and Veggies
While the hashbrowns are baking, heat a skillet over medium heat. Cook the crumbled breakfast sausage until browned. Remove and drain excess grease. In the same skillet, sauté the diced onion and bell pepper for 2–3 minutes until softened.
Step 3: Whisk the Eggs
In a large bowl, whisk together eggs, milk, garlic powder, salt, and pepper until well combined.
Step 4: Assemble the Casserole
Spread the cooked sausage and sautéed vegetables evenly over the baked hashbrowns. Sprinkle half of the shredded cheese on top. Pour the egg mixture evenly over everything. Sprinkle the remaining cheese on top.
Step 5: Bake Until Golden
Bake for 35–40 minutes, or until the eggs are fully set and the top is golden brown. Let it cool for 5 minutes before slicing.
Step 6: Serve and Enjoy!
Slice into squares and serve warm. Pair it with fresh fruit, toast, or a side of salsa for extra flavor.
What to Serve with Hashbrown Breakfast Casserole
- Fresh fruit salad – A refreshing contrast.
