Can I Use Fresh Potatoes Instead of Frozen Hash Browns?

Yes, you can! Freshly grated potatoes work well, just be sure to squeeze out excess moisture to avoid a soggy base. Frozen hash browns, though, are the ultimate time-saver and ensure even texture throughout the casserole.

How To Make the Sausage, Egg and Hash Brown Breakfast Casserole

Step 1: Brown the Sausage

Cook breakfast sausage in a skillet over medium heat until fully browned. Break it into crumbles as it cooks. Drain any excess fat and set aside.

Step 2: Prepare the Baking Dish

Grease a 9×13-inch baking dish. Spread the hash browns evenly across the bottom.

Step 3: Layer the Casserole

Top the hash browns with cooked sausage, followed by chopped red bell peppers and green onions. Sprinkle shredded cheddar cheese evenly over the top.

Step 4: Whisk the Egg Mixture

In a large bowl, whisk together eggs, milk, salt, and pepper until fully combined. Pour the mixture over the layered ingredients in the baking dish.

Step 5: Bake to Perfection

Bake at 375°F (190°C) for 40-45 minutes, or until the center is set and the top is golden. Let rest for 5-10 minutes before slicing.
