this Recipe

You know that magical feeling when you pull a hot, cheesy casserole out of the oven, and the whole kitchen smells amazing? Yeah, this casserole was born from one of those moments.

It all started on Christmas morning last year. I had a house full of guests, coffee brewing, and a counter covered in wrapping paper scraps. I wanted a no-fuss breakfast that felt special without me flipping pancakes for an hour. Enter: hash brown egg casserole.

I had a pack of frozen hash browns in the freezer (a rare miracle, honestly), leftover ham from the night before, and enough eggs to feed a small army. So, I threw everything together, hoping for the best. And you know what? It turned out amazing.

Since then, it’s become my go-to for brunches, lazy weekends, and basically any time I need a crowd-pleaser.

Ingredient Notes:

This recipe keeps things simple, but every ingredient pulls its weight.

Pro Tip: Use smoked cheddar for an extra cozy twist—it’s so good.

How To Make Hash Brown Egg Casserole?

Trust me, you won’t believe how simple this is.

Step 1: Preheat and Prep

Set your oven to 325°F and grease a 9×13-inch baking dish. Nobody wants to scrape stuck cheese off the pan, right?

Step 2: Layer the Hash Browns

Lay the hash brown patties in a single layer at the bottom of your dish. No need to thaw them—straight from the freezer works perfectly.

Step 3: Add the Cheese, Ham & Scallions

Sprinkle the cheddar and Monterey Jack cheese evenly over the hash browns. Next, toss on the diced ham and those fresh scallions.

Step 4: Make the Egg Mixture

In a medium bowl, whisk together the eggs, milk, salt, garlic powder, and dry mustard. Give it a quick taste to make sure it’s seasoned just right.

Step 5: Pour and Bake

Pour the egg mixture over your layered ingredients. Cover the dish with foil and bake for 25 minutes.

Remove the foil and bake another 20 minutes until the top is golden, bubbly, and set in the center.

Step 6: Rest and Serve

Let the casserole sit for about 5 minutes before slicing. This helps it firm up a bit—plus, it makes cutting way easier.

Storage Options:

This casserole saves beautifully, making it perfect for meal prep.

• Fridge: Store in an airtight container for up to 4 days.
• Freezer: Wrap slices individually in foil and freeze for up to 2 months.
• Reheat: Warm in the oven at 325°F or microwave for a quick breakfast fix.

Variations and Substitutions:

The beauty of this casserole? It’s endlessly customizable.

• Switch Up the Meat: Try cooked bacon, crumbled sausage, or even turkey bacon.
• Different Cheeses: Swiss, Colby Jack, or a spicy Pepper Jack work great.
• Veggie Boost: Toss in spinach, mushrooms, or roasted red peppers.
• Dairy-Free: Use almond milk and vegan cheese for a lactose-friendly version.

Pro Tip: Love spice? Add a dash of cayenne or a sprinkle of red pepper flakes!
