Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
If using fresh potatoes, dice them into small cubes and cook in a skillet over medium heat until golden and tender. For frozen hash browns, cook until crisp. Set aside.
In the same skillet, sauté bell peppers and spinach for 2–3 minutes until softened. Remove from heat and cool slightly.
In a large bowl, whisk together eggs, milk, salt, pepper, garlic powder, and onion powder until smooth and combined.
Spread cooked potatoes evenly across the bottom of the prepared baking dish. Add diced sausage, sautéed vegetables, and half of the shredded cheese.
Pour the egg mixture evenly over the layered ingredients. Gently press down with a spatula to ensure everything is evenly distributed.
Sprinkle the remaining cheese and green onions on top.
Bake uncovered for 40–45 minutes, or until the center is set and the top is golden brown. A knife inserted into the center should come out clean.
Allow the casserole to rest for 10 minutes before slicing. This helps the layers set and makes cutting easier.
Garnish with diced tomatoes or fresh herbs if desired, then serve warm.

Notes

You can assemble this casserole the night before and refrigerate it overnight. Bake fresh in the morning for a quick and hearty meal.
For a vegetarian option, omit the sausage and add extra vegetables like mushrooms, zucchini, or broccoli.
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave before serving.
To freeze, wrap portions in foil and store for up to 2 months. Reheat at 350°F until warmed through.
Add a touch of spice with diced jalapeños, chili flakes, or pepper jack cheese for a flavorful kick.
