Sausage and Cheese English Muffin Casserole: Step-by-Step Guide

Step 1: Cook the Sausage
In a large skillet over medium heat, melt the butter and add the ground breakfast sausage. Cook until browned and fully cooked, breaking it apart with a spatula as it cooks. Drain any excess fat, and then add the chopped onion to the skillet. Sauté for about 3-4 minutes until the onion is soft and translucent.
Step 2: Prepare the Base
In a large mixing bowl, combine the thawed hash browns and the pieces of English muffins. Stir in the cooked sausage and onion mixture, ensuring everything is evenly distributed.
Step 3: Mix the Egg Mixture
In another bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until well combined. Pour the egg mixture over the hash brown and sausage mixture, gently folding everything together until the bread is well coated.
Step 4: Add the Cheese
Fold in the shredded cheddar and mozzarella cheeses, reserving a little of each for topping. Transfer the mixture into a greased 9×13-inch baking dish, spreading it evenly.
Step 5: Top and Bake
Sprinkle the reserved cheeses on top of the casserole. Cover with foil and bake in a preheated oven at 350°F (175°C) for 40 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the casserole is set and the cheese is bubbly and golden.
Step 6: Serve and Enjoy
Allow the casserole to cool for a few minutes before slicing into squares. Serve warm, and watch as everyone digs in!
