Easy Brunchhhh Casserole – Cheesy 45-Minute Crowd Pleaser

Picture this: a lazy Sunday, sunlight streaming through the kitchen window, and the smell of something warm and cheesy drifting from the oven. That’s when Brunchhhh comes to life – a dish born from my travels through the cozy diners of the American Midwest, where brunch is practically a religion.

This isn’t just any breakfast casserole. It’s a one-pan wonder that combines fluffy eggs, golden hash browns, savory sausage, and a blanket of melted cheddar, all baked to bubbly perfection. I’ve tweaked it over years of weekend experiments, and now it’s my go-to for feeding a crowd without breaking a sweat.

Whether you’re hosting a family gathering or just want to treat yourself to something special, Brunchhhh delivers comfort and joy in every bite. And the best part? It comes together in just 15 minutes of prep, leaving you more time to sip coffee and enjoy the morning.

About the Ingredients

1 lb (450g) breakfast sausage

Use mild or spicy; you can substitute with bacon or turkey sausage for a lighter option.

1 tbsp (15ml) olive oil

For sautéing the veggies; you can use butter or cooking spray instead.

1 medium yellow onion, diced

Adds sweetness and depth; a red onion works too for a milder flavor.

1 red bell pepper, diced

For color and crunch; any bell pepper color works, or use roasted red peppers from a jar.

2 cups (200g) frozen hash browns, thawed

Thawed and patted dry to avoid excess moisture; you can use fresh shredded potatoes.

8 large eggs

The base of the casserole; use farm-fresh for the best flavor.

1 cup (240ml) whole milk

Adds creaminess; you can use 2% or a dairy-free alternative like oat milk.

2 cups (200g) shredded sharp cheddar cheese

Sharp cheddar gives a bold flavor; try Gruyère or pepper jack for a twist.

1 tsp (5g) salt

Adjust to taste; use kosher salt for even seasoning.

1/2 tsp (2g) black pepper

Freshly ground is best; you can add a pinch of cayenne for heat.

1/4 cup (15g) chopped fresh chives

For garnish; you can use green onions or parsley instead.

Tips & Tricks

• Don’t skip patting the hash browns dry – excess moisture makes the casserole watery.
• If you’re making this ahead, assemble the casserole and refrigerate unbaked overnight; add 10 minutes to the baking time.
• Let the casserole rest for 5 minutes after baking to set, making it easier to slice and serve.

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 375°F (190°C). Grease a 9×13-inch (23x33cm) baking dish with butter or cooking spray.

2. Cook the Sausage

In a large skillet over medium-high heat, cook the sausage, breaking it into crumbles, until browned and cooked through, about 6-8 minutes. Remove with a slotted spoon and set aside.

3. Sauté the Veggies

In the same skillet, add the olive oil, onion, and bell pepper. Sauté over medium heat until softened, about 4-5 minutes. Remove from heat.

4. Mix the Base

In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined.

5. Layer the Casserole

Spread the hash browns evenly in the prepared dish. Top with the sausage and vegetable mixture. Pour the egg mixture over everything, then sprinkle with the shredded cheddar cheese.

6. Bake to Golden Perfection

Bake in the preheated oven for 35-40 minutes, until the edges are golden brown and the center is set (a knife inserted comes out clean). The internal temperature should reach 165°F (74°C).

7. Rest and Garnish

Let the casserole rest for 5 minutes, then sprinkle with fresh chives. Slice and serve warm.

Delicious Variations

Vegetarian

Omit the sausage and add sautéed mushrooms, spinach, and zucchini.

Southwest

Add diced green chiles, use pepper jack cheese, and top with salsa and avocado.
