How to Make Breakfast Casserole
Step 1: Preheat the Oven
Preheat the oven to 350°F. Grease a 3-quart baking dish to ensure nothing sticks.
Step 2: Arrange Hash Browns
Arrange the frozen hash brown patties evenly in the bottom of the greased baking dish. This will serve as a sturdy base for your casserole.
Step 3: Cook Sausage and Vegetables
Heat a large skillet over medium-high heat. Add the pork sausage and cook until browned. Break it into small pieces as it cooks. Add finely diced onions and cook for another 1-2 minutes until they become translucent. Remove from heat and mix in diced red and green bell peppers.
Step 4: Combine Sausage Mixture with Cheese
Add the cooked sausage mixture on top of the hash browns in the baking dish. Evenly sprinkle shredded cheddar cheese over this layer for added flavor.
Step 5: Whisk Eggs and Milk
In a large bowl, whisk together eggs, milk, salt, and black pepper until fully combined. This mixture will bind everything together while baking.
Step 6: Bake Casserole
Pour the egg mixture over the layered ingredients in the baking dish. Bake uncovered for 50-60 minutes or until eggs are set. You can test by cutting through the center; if runny, bake longer.
Step 7: Serve and Enjoy!
Once baked to perfection, let cool slightly before serving. Pair with ketchup if desired and enjoy your delicious breakfast casserole!
