Ingredients

- 1 (30 oz) package frozen shredded hashbrowns, thawed
- 2 cups diced cooked ham
- 1 small onion, finely chopped
- 1 red bell pepper, diced
- 8 large eggs
- 1½ cups whole milk
- 2 cups shredded cheddar cheese
- 1 tsp Dijon mustard
- ½ tsp garlic powder
- Salt and freshly ground black pepper, to taste
- 2 tbsp chopped fresh chives (optional)
- Nonstick spray or butter, for greasing
Instructions
- Preheat & Prep: Heat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or butter. Trust me, you don’t want this beauty sticking.
- Layer Hashbrowns: Spread the thawed hashbrowns evenly in the bottom of the dish. Press gently so you get a crisp bottom—no one likes a soggy base.
- Sauté Veggies & Ham: In a skillet over medium heat, toss in diced onion and red bell pepper. After 3 minutes, add the ham and cook until veggies soften and ham edges brown.
- Mix Egg Base: Whisk eggs, milk, Dijon mustard, garlic powder, salt, and pepper in a bowl. Make sure it’s smooth—no weird lumps, please.
- Assemble: Sprinkle half of the shredded cheddar over hashbrowns. Evenly layer the ham-vegetable mix, then pour the egg mixture on top.
- Top & Bake: Finish with the remaining cheddar cheese. Slide the dish into the oven.
- Bake Time: Bake for 40–45 minutes until the center sets and the cheese bubbles. If the top browns too fast, loosely tent with foil.
- Rest: Let it cool for 5–10 minutes before slicing. This helps the layers settle so your squares stay intact.
- Garnish: Sprinkle chopped chives or green onions right before serving for a fresh pop of color.
- Serve Hot: Use a sharp knife or spatula to cut into squares. Watch ‘em disappear in seconds.
- Clean Up Tip: Soak your baking dish in warm soapy water while you eat—less scrubbing later, trust me.
- Enjoy! Grab a plate, dig in, and bask in the glory of your brunch triumph.
Layering Tips
For the crispiest bottom, press the hashbrowns firmly and avoid overcrowding the dish. Ever wondered why some bites are soggy? They usually skip this crucial step. IMO, a firm press guarantees a golden crust that holds up to every gooey bite.
Baking & Cheese Melting Tips
If your cheese gets too dark before the eggs set, drop the oven temp by 10°F or drape foil over the top. Want bonus browning? Blast the broiler for the last 1–2 minutes—just watch closely so it doesn’t burn.
Make Ahead & Overnight Options
This breakfast casserole make ahead approach might be my favorite hack. Simply assemble everything up to the cheese topping, cover tightly, and refrigerate overnight. In the morning, pull it out, let it sit at room temp for 20 minutes, then bake as directed. For an overnight breakfast casserole with hashbrowns twist, skip the milk in the egg mix and add it right before baking to keep things extra fresh.
Variations
Want to mix things up? This Cheesy Hashbrown and Ham Breakfast Bake plays well with swaps and add-ins. Turn it into a vegetarian brunch casserole by swapping ham for sautéed mushrooms and spinach. Craving a spicy kick? Stir in chopped jalapeños or a sprinkle of red pepper flakes.
- Tortilla Quiche Bake: Replace hashbrowns with torn flour tortillas for a Tex-Mex twist.
- Mini Quiche Recipes: Divide the mixture into muffin tins for grab-and-go mini quiches—perfect for a breakfast basket or kids’ lunchbox.
- Easy Tater Tot Casserole: Swap hashbrowns for tater tots and top with a cheddar-panko mix for extra crunch.
Serving & Tips
This dish shines at any brunch potluck. Serve alongside a fresh fruit salad or a light arugula salad to balance the richness. Looking for a cozy seasonal touch? Add a sprinkle of smoked paprika or swap cheddar for Gruyère when cooler weather hits.
Storage is a breeze. Cover leftovers tightly and refrigerate for up to 3 days, or freeze individual slices wrapped in foil for up to 2 months. Reheat at 325°F (165°C) until warmed through—no microwave sogginess allowed.
- Serving Ideas: Pair with fresh pico de gallo, hot sauce, or avocado slices.
- Storage Tips: Cool completely before covering to avoid sogginess.
- Seasonal Touch: Stir in roasted butternut squash or kale in fall.
- Brunch Casserole Hacks: Add cooked sausage for a heartier twist.

Notes
Tried this recipe?
Let us know how it was!FAQs
Can I use fresh potatoes instead of frozen hashbrowns?
Absolutely! Peel and shred 3 large russet potatoes, then rinse and dry them thoroughly before using. You might need to pre-cook the shredded potatoes for 5–7 minutes to remove excess moisture. Otherwise, follow the recipe as written.
How do I make this dish gluten-free?
Just double-check your frozen hashbrowns and mustard for gluten-free labels—most are already safe. If you’re adding mix-ins like sausage or spices, verify those too. The rest of the ingredients (eggs, cheese, ham) are naturally gluten-free.
Can I swap the ham for another protein?
Yes! Cooked bacon, sausage crumbles, or diced turkey work beautifully. For a veggie-friendly version, skip meat and stir in sautéed mushrooms, spinach, or sun-dried tomatoes. You’ll still get that hearty, satisfying feel.
What’s the best way to reheat leftovers?
For the crispiest results, reheat individual slices in a 325°F oven for 10–12 minutes. You can also microwave on medium power for 1–2 minutes, but you might lose some of that glorious crust.
