Step-by-Step Instructions to Make Sausage Potato Casserole

1. Prepare Your Ingredients

Start by gathering all your ingredients. Chop the onion, mushrooms, bell peppers, and green onions. Set them aside for easy access while cooking.

2. Cook the Sausage and Vegetables

• Heat a large skillet over medium heat. Add the Italian sausage, breaking it into small crumbles as it cooks.
• Once the sausage is browned and cooked through, remove it from the skillet and set it aside.
• In the same skillet, add the chopped onions, mushrooms, and bell peppers. Sauté them for about 5 minutes, or until the vegetables are tender.

3. Prepare the Egg Mixture

• In a mixing bowl, whisk together the eggs, milk, salt, black pepper, and red pepper flakes. This mixture will bind the casserole together and add a creamy texture.

4. Assemble the Casserole

• Preheat your oven to 375°F (190°C).
• Grease a 9×13-inch casserole dish with cooking spray or a bit of oil.
• Spread the frozen hash brown potatoes evenly across the bottom of the dish.
• Layer the cooked sausage and sautéed vegetables over the potatoes.
• Pour the egg mixture over the top, ensuring it coats everything evenly.
• Sprinkle the shredded mozzarella cheese and chopped green onions over the top.

5. Bake the Casserole

• Place the casserole dish in the preheated oven.
• Bake for 35–40 minutes, or until the eggs are set, and the cheese is bubbly and golden brown.
• Remove from the oven and let it cool for 5 minutes before serving.

Tips for Making the Best Sausage Potato Casserole

Feeding a crowd? This recipe is easy to double. Just use a larger baking dish and adjust the cooking time slightly.
