Ingredients

Gather these simple, crowd-friendly staples. You’ll notice I favor convenience without skimping on flavor—hello, shortcut-friendly hashbrowns! You can also customize toward a healthy breakfast casserole by swapping in low-fat dairy or adding extra veggies.
- 1 (30 oz) bag frozen shredded hashbrowns, thawed
- 2 cups diced cooked ham (or leftover rotisserie chicken/turkey)
- 1 small onion, finely chopped
- 1 red bell pepper, diced (optional for color & nutrients)
- 8 large eggs, lightly beaten
- 1¾ cups whole milk (or half-and-half for extra creaminess)
- 2 cups shredded cheddar cheese (plus extra for topping)
- 2 tsp Dijon mustard (adds a nice zing)
- 1 tsp garlic powder
- ½ tsp paprika
- Salt and pepper, to taste
- Chopped fresh chives or parsley, for garnish
Instructions
I love recipes that feel like a classic egg casserole or egg frittata but on a bigger scale—perfect for a breakfast basket spread or a potluck centerpiece. This section doubles as a “Breakfast Casserole Make Ahead” and “Overnight Breakfast Casserole With Hashbrowns” guide. Ready? Let’s rock this brunch!
- Preheat your oven to 375°F (190°C). Grease a 9×13” baking dish with cooking spray or a thin coat of butter.
- In a large bowl, combine the thawed hashbrowns, diced ham, chopped onion, and bell pepper. Spread the mixture evenly in the prepared baking dish.
- In another bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, paprika, and a pinch of salt & pepper until smooth.
- Pour the egg mixture evenly over the hashbrowns and ham. Gently press down so the potatoes absorb some of the liquid.
- Sprinkle 1½ cups of shredded cheddar over the top. Cover with foil and refrigerate if you’re making this overnight (highly recommended!).
- If baking immediately, place the covered dish in the oven and bake for 30 minutes. Remove the foil and bake an additional 15–20 minutes, or until the eggs are set and the cheese is bubbly & golden.
- For an overnight bake: Let the casserole rest in the fridge for 8–12 hours, then bake covered for 35 minutes. Uncover and bake 20 more minutes.
- Once done, let it sit for 5 minutes. Top with extra cheddar and a sprinkle of fresh chives or parsley before slicing.
- Cut into squares or rectangles and serve warm. Enjoy every cheesy, savory bite!
Variations
Switch things up to suit your taste buds or dietary needs. These creative twists keep the recipe fresh and let you claim it as your own:
- Veggie-Loaded Brunch: Swap half the ham for a cup of sautéed spinach, mushrooms, or zucchini. You’ll boost the nutrient profile for a slightly healthier breakfast casserole.
- Spicy Southwest: Stir in a can of diced green chilies, use pepper jack cheese, and top with sliced jalapeños. It’s like a mini tortilla quiche bake with a kick.
- Mini Quiche Muffins: Line a muffin tin with paper liners, then fill each cup one-third full with hashbrowns and ham, pour in the egg mixture, and bake 20–25 minutes at 350°F. Perfect for grab-and-go breakfasts or a mini quiche recipes party!
Serving & Tips

Serve this bake straight from the dish at room temperature or lightly reheated. Pair it with fresh fruit, a side salad, or homemade salsa for a complete brunch basket spread. If you’re hosting a brunch potluck, set it next to a DIY omelet station or an egg frittata bar—guests love options!
Storage stays simple: cover leftovers and refrigerate up to 4 days. For longer stints, cut into portions, wrap tightly, and freeze. To reheat, thaw (if frozen) and bake at 350°F for 15–20 minutes until warmed through.
Looking for a cozy seasonal twist? Add a dash of nutmeg and swap cheddar for Swiss or Gruyère, then top with crisped prosciutto slices right before serving. Instant fall-friendly brunch casserole vibes!
