this Recipe

Let me set the scene: It’s a slow Sunday morning. The coffee’s brewing, the house smells like bacon from someone’s late-night snack, and I’ve got a bunch of hungry people asking, “What’s for breakfast?”

Now, I could stand at the stove flipping pancakes while my coffee gets cold, or… I could throw everything into a baking dish and actually enjoy my morning.

That’s how this Brunch Casserole became my go-to. It’s the kind of meal that looks fancy but takes zero effort. Everything just bakes together into this warm, cheesy, slightly crispy, and ridiculously satisfying dish. And the best part? Leftovers taste just as amazing the next day. (Not that there are ever leftovers in my house.)

If you love lazy weekend breakfasts, cheesy goodness, and a meal that feeds a crowd with almost no work, then this is your kind of recipe.

Ingredient Notes:

This is the kind of recipe where simple ingredients come together to create something amazing.

Pro Tip: Want to take it to the next level? Add a dash of hot sauce or a sprinkle of smoked paprika for extra depth.

How To Make Brunch Casserole?

Step 1: Preheat & Prep

Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish. No one wants to scrape baked-on cheese off a pan.

Step 2: Cook the Sausage & Peppers

Heat a skillet over medium heat. Cook the sausage for about 4 minutes, breaking it up as it browns. Once it’s halfway cooked, toss in the chopped bell peppers and let them soften for another 4 minutes.

Step 3: Assemble the Layers

Transfer the sausage and peppers into the greased baking dish. Add the thawed hash browns, mix everything up, and top it with 1 cup of cheese.

Step 4: Mix the Eggs & Milk

In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until smooth. Stir in the chopped green onions for a fresh, mild bite.

Step 5: Pour & Bake

Pour the egg mixture over the casserole. Sprinkle the remaining 1 cup of cheese on top.

Bake for 40-50 minutes, or until the eggs are set and the cheese is golden brown.

Step 6: Let It Rest & Serve

Let the casserole sit for 5-10 minutes before slicing. This helps it hold together when serving. Then, dig in and enjoy!

Storage Options:

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezing: Wrap individual portions in foil and freeze for up to 2 months.
• Reheating: Microwave for 30-60 seconds, or bake at 350°F for 15 minutes for a fresh-from-the-oven taste.

Variations and Substitutions:

One of the best things about this casserole? You can switch it up however you like.

• Swap the Protein – Try bacon, ham, or even cooked chicken.
• More Veggies? Yes, Please! – Mushrooms, spinach, or diced zucchini add great texture.
• Cheese Lovers Unite – Swap cheddar for Swiss, feta, or pepper jack for a fun twist.
• Spice It Up – Add diced jalapeños or a pinch of cayenne for extra heat.
• Low-Carb Option – Skip the hash browns and add more eggs for a crustless version.

What to Serve with Brunch Casserole?

This dish is already a full meal, but if you want to round it out, here are some ideas:

• Fresh Fruit Salad – A light, refreshing contrast to the cheesy richness.
• Buttery Biscuits or Toast – Because carbs are never a bad idea.
• Crispy Bacon or Sausage Links – Extra protein for extra satisfaction.
• Avocado Slices or Guacamole – A creamy, fresh twist.
• Mimosas or Fresh Orange Juice – Because brunch isn’t brunch without a good drink.

Frequently Asked Questions:

Do I need to thaw the hash browns first?

Yes! If you don’t, they’ll release too much water and make the casserole soggy.

How do I know when it’s done baking?

The top should be golden, and the eggs should be fully set. Insert a knife in the center—if it comes out clean, you’re good to go!

Can I use egg whites instead of whole eggs?

Absolutely! Swap the whole eggs for 8-10 egg whites for a lighter version.

Notes

Absolutely, adapting this Brunch Casserole for a gluten-free lifestyle is simple and ensures that everyone can indulge in this comforting dish without hesitation. To guarantee it meets gluten-free standards, select a sausage that is labeled as gluten-free; many sausages contain fillers that may include gluten. Next, double-check your hash browns — though inherently gluten-free, as they're made from potatoes, they can sometimes be processed in facilities that handle wheat products. Opt for a brand that confidently asserts its gluten-free status. As for the remaining ingredients — eggs, milk, cheese, and spices — they are naturally gluten-free.
