Sausage Hashbrown Breakfast Casserole

For this delicious breakfast casserole, you’ll need the following ingredients:

Optional Add-Ons

• Mushrooms – For an extra umami boost.
• Jalapeños – If you love a little spice.
• Feta cheese – For a tangy twist.
• Fresh herbs – Like parsley or chives for a bright finish.

Tools You’ll Need

• Mixing bowls
• Whisk
• Skillet
• Baking dish (9×13 inch)
• Oven mitts

Step-by-Step Instructions

Step 1: Preheat & Prep

Preheat your oven to 350°F. Grease a 9×13-inch baking dish with nonstick spray or butter to prevent sticking. This ensures that the casserole comes out perfectly without any bits getting stuck to the pan.

Step 2: Cook the Sausage & Veggies

Heat a large skillet over medium heat. Add the pork breakfast sausage, breaking it apart with a spatula as it cooks. Stir occasionally until browned and fully cooked, about 7-8 minutes. Remove the sausage from the pan and set aside.

In the same skillet, add onions and red peppers and sauté for 3-4 minutes until softened. This enhances their natural sweetness and adds a deeper flavor to the casserole.

Step 3: Mix the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, salt, and pepper until well combined. Make sure the eggs are fully incorporated to ensure an even, fluffy texture when baked.

Step 4: Layer the Ingredients

Spread the frozen hashbrowns evenly across the bottom of the greased baking dish. Next, layer the cooked sausage and sautéed veggies over the hashbrowns. Sprinkle chopped spinach on top, then pour the egg mixture over everything, ensuring it spreads evenly. Finally, sprinkle cheddar cheese on top.

Step 5: Bake

Bake uncovered for 25-30 minutes, or until the eggs are set, and the top is golden brown. You can check for doneness by inserting a knife into the center—if it comes out clean, it’s ready!

Step 6: Cool & Serve

Let the casserole cool for 5-10 minutes before slicing. This allows the ingredients to settle and makes serving much easier.
