How to Make Breakfast Sausage & Veggie Hash Brown Casserole Recipe
Step 1: Crispy Hash Browns Are Key
Start by heating olive oil in a large skillet over medium-high heat. Spread your thawed hash browns evenly and let them fry without stirring for about 5 to 7 minutes. Patience here is crucial because this step creates the golden, crispy crust that adds incredible texture. Once golden and crispy, carefully flip in sections and cook another 4 to 5 minutes. Then transfer this crispy goodness to a greased baking dish—you’ll thank yourself later for this crunch!
Step 2: Perfectly Cooked Breakfast Sausage
Using the same skillet, cook the breakfast sausage, breaking it into small crumbles. This is where your kitchen will start smelling irresistible. Cook it until it’s nicely browned and fully cooked through, then transfer the sausage into the baking dish with the hash browns. Leave just a bit of the flavorful sausage grease in the pan to work its magic with the veggies.
Step 3: Sautéed Veggies for Flavor and Color
Now add your onion, bell peppers, and mushrooms to the skillet and sauté them for about 7 to 10 minutes until they soften and start to caramelize beautifully. Then toss in the garlic and cook for 2 more minutes—garlic’s aroma is truly an essential love note in this recipe. Finally, stir in the spinach and Old Bay seasoning, letting the spinach wilt just slightly. Combine all the veggies with the sausage and hash browns in the baking dish for a full flavor explosion.
Step 4: Egg Mixture Magic
In a large bowl, whisk together the eggs, black pepper, and half-and-half until smooth and creamy. Stir in 1½ cups of the shredded sharp cheddar cheese to give your casserole richness and that irresistible melty texture baked inside.
Step 5: Bring It All Together
Pour your cheesy egg mixture evenly over the sausage and veggie hash in the baking dish. Give it a gentle stir to distribute everything evenly—this ensures every slice has a perfect balance of textures and flavors. Top the casserole with the remaining ½ cup of cheddar cheese and a few twists of black pepper to seal the deal.
Step 6: Bake to Perfection
Pop the casserole into a preheated 350°F (175°C) oven and bake for 45 to 55 minutes. The center should set firmly and not jiggle. If the cheese browns too quickly, just loosely cover the dish with foil to keep the top from burning while the inside finishes cooking.
Step 7: Rest and Garnish
Once baked, allow the casserole to cool for at least 10 minutes before slicing. This little pause helps it firm up further, making it easier to serve and enjoy. Sprinkle with fresh chopped green onions and creamy avocado slices for an extra touch of flavor and freshness.

FAQs
Can I use turkey sausage instead of pork sausage?
Absolutely! Turkey sausage is a leaner alternative and will work just as well in this breakfast sausage & veggie hash brown casserole recipe while reducing the fat content.
Do I have to use Old Bay seasoning?
Old Bay adds a unique savory flavor, but if you don’t have it on hand, seasoned salt or your favorite spice blend can be used instead without compromising the overall deliciousness.
What if I don’t have hash browns?
Frozen hash browns are easiest for this recipe, but you can use fresh shredded potatoes—just squeeze out excess moisture first to achieve the same crispiness in the skillet.
Can this recipe be made vegetarian?
Yes! Simply omit the sausage and add more mushrooms or plant-based sausage alternatives to keep the hearty flavors intact.
How long does the casserole need to rest before serving?
Letting it rest for at least 10 minutes after baking helps it set nicely so slices hold together well and flavors meld beautifully.

Instructions
- Cook Hash Browns: Heat 1 tablespoon olive oil in a large nonstick skillet over medium-high heat.

Transfer to a greased 9×13-inch baking dish.
- Cook Sausage: In the same skillet, cook the breakfast sausage over medium-high heat, breaking it into crumbles, until browned and cooked through. Use a slotted spoon to transfer the cooked sausage to the baking dish, leaving behind 2 tablespoons of grease. Drain and discard excess grease if necessary.
- Sauté Vegetables: Add the chopped onion, bell peppers, and mushrooms to the skillet with the remaining sausage grease and sauté for 7-10 minutes, stirring occasionally, until softened and browned. Add the minced garlic and continue sautéing for 2 minutes, stirring frequently. Toss in the fresh spinach and Old Bay seasoning, stirring until the spinach is just wilted. Transfer this mixture to the baking dish and toss briefly with the hash browns and sausage to combine.
- Prepare Egg Mixture: In a large bowl, whisk together the 12 eggs, 1/4 teaspoon black pepper, and 1/2 cup half-and-half. Stir in 1½ cups of shredded sharp cheddar cheese.
- Combine and Layer: Pour the egg mixture evenly over the sausage and vegetable hash browns in the baking dish. Gently stir to mix everything evenly. Sprinkle the remaining ½ cup of cheddar cheese on top along with a few extra twists of black pepper.
- Bake Casserole: Preheat the oven to 350°F (175°C). Bake the casserole for 45–55 minutes, or until the center is set and no longer jiggly. If the top browns too quickly, loosely tent with aluminum foil to prevent burning.
- Cool and Serve: Let the casserole cool for at least 10 minutes before slicing. Garnish with sliced avocado and chopped green onions if desired. Serve warm and enjoy!
