Ingredients

This Hashbrown Breakfast Casserole ingredient list is surprisingly simple but delivers incredible comfort! Here’s what you’ll need:
- 32 ounces frozen shredded hashbrowns, thawed – the crunchy base of your cheesy hashbrown casserole
- 1 pound breakfast sausage, cooked and crumbled – for savory, meaty flavor
- 2 cups shredded cheddar cheese – sharp cheddar adds rich, melt-in-your-mouth goodness
- 8 large eggs – the binder that makes the casserole fluffy and full-bodied
- 2 cups whole milk – creaminess for the custard base
- 1/2 cup diced onion – adds gentle sweetness and subtle bite
- 1 teaspoon garlic powder – boosts flavor quietly under the cheese
- Salt and pepper, to taste
The secret to amazing Hashbrown Breakfast Casserole is using thawed frozen hashbrowns instead of fresh potatoes. They hold their texture well, soak up the creamy custard, and save loads of prep time. You can find the best ingredients for this Hashbrown Breakfast Casserole at your local grocery store’s freezer aisle and fresh meat counter.
If you want to splurge on one Hashbrown Breakfast Casserole ingredient, make it the cheese—using a high-quality sharp cheddar really lifts the flavor. Feel free to swap breakfast sausage for diced ham or cooked bacon if that’s your preference, and try adding chopped bell peppers or mushrooms for a veggie twist.
For a lighter option, whole milk can be replaced with half-and-half or even a dairy-free alternative that works well in baking, like almond milk. If you want to prep ahead, cook the sausage and chop your veggies a day earlier. Store all ingredients in airtight containers until ready to combine.
This approachable ingredient lineup makes the Hashbrown Breakfast Casserole a breeze to pull together, even on busy mornings!
Let’s Make This!
Let’s get cooking on this beautiful Hashbrown Breakfast Casserole! Follow these steps for a lovely, oven-baked breakfast casserole everyone will adore:
- Preheat your oven to 350°F (175°C). This temperature cooks everything gently so your cheesy hashbrown casserole sets perfectly without drying out.
- Prepare your sausage by cooking it in a skillet over medium heat until browned and crumbled, about 7-10 minutes. Drain excess grease. While the meat cools slightly, move on to the rest.
- In a large bowl, whisk together eggs, milk, garlic powder, salt, and pepper. This creamy custard mix will soak into the hashbrowns for a tender finish.
- Combine the thawed hashbrowns, diced onion, cooked sausage, and half the cheese in a greased 9×13-inch baking dish. Give it a gentle toss so flavors begin to mingle.
- Pour the egg mixture evenly over the hashbrown combo. Press down lightly with a spatula to make sure everything is covered but avoid squashing the texture.
- Sprinkle the remaining cheese on top—this is where the cheesy hashbrown casserole magic happens, creating that irresistible baked crust.
- Bake uncovered for about 45-55 minutes. You want the top golden and bubbly. Your Hashbrown Breakfast Casserole should have a gentle jiggle in the middle, and a toothpick inserted near the center should come out mostly clean.
- Let it rest for 10 minutes before serving. This step helps the casserole set for easy slicing and keeps all those flavors locked in.
Don’t worry—your Hashbrown Breakfast Casserole is going to turn out beautifully! Here’s a helpful tip: if your oven runs hot, check at the 40-minute mark to avoid over-browning. While your casserole is baking, take a moment to enjoy that amazing aroma filling your kitchen—there’s nothing like it.

Serving & Presentation
When it’s time to serve this Hashbrown Breakfast Casserole, simplicity shines. Slice into hearty squares and plate them warm with a sprinkle of fresh chopped parsley for a pop of color and brightness. It pairs wonderfully with a crisp green salad or fresh fruit to balance the richness.
I love serving this casserole for weekend brunches, holiday mornings, or easy gatherings where everyone can help themselves. It creates the sweetest moments at family dinners and brings that feeling of being fully at home.
For side ideas that complement your Hashbrown Breakfast Casserole, think fresh tomatoes, roasted asparagus, or even some baked apples for a little sweetness contrast. A dollop of sour cream or a drizzle of your favorite hot sauce can add another layer of deliciousness.
Leftovers? They heat up beautifully the next day. Try a quick reheat in your oven or microwave, or even cube pieces to toss into a breakfast scramble or a loaded omelet. If you want to mix it up seasonally, adding sautéed spinach or roasted zucchini during the assembly can be a comforting variation I’ve tested and loved.

FAQs
Let’s tackle some of the questions fellow food lovers ask about my Hashbrown Breakfast Casserole:
Can I make this Hashbrown Breakfast Casserole ahead of time?
Absolutely! This is a wonderful make-ahead breakfast dish. Assemble it the night before, cover it tightly, and refrigerate. When ready, bake for about 60-65 minutes since it’s going in cold, and enjoy fresh, warm casserole magic in the morning.
What if I don’t have breakfast sausage?
No worries—bacon, diced ham, or even cooked ground turkey work beautifully. You can also keep it vegetarian by swapping sausage out and adding sautéed mushrooms or bell peppers.
How do I know when my Hashbrown Breakfast Casserole is perfectly done?
I look for a golden, bubbly top, a slight jiggle in the middle, and that a toothpick inserted near the center comes out mostly clean. Letting it rest a bit after baking helps everything set for easier slicing.
Can I freeze leftovers?
Yes! Cool completely before wrapping tightly. Defrost overnight in the fridge before reheating. It keeps well for about 2-3 months in the freezer.
Is there a gluten-free version of this Hashbrown Breakfast Casserole?
If your sausage and hashbrowns are gluten-free (always check labels), this recipe naturally fits gluten-free diets perfectly.
For more thorough FAQs and helpful variations, Spend With Pennies has excellent answers that I trust for easy breakfast casseroles like this hashbrown one.
What’s your best tip for ensuring the casserole isn’t soggy?
Make sure your hashbrowns are thawed and well-drained—excess moisture can make the casserole watery. Also, don’t overmix once you add the egg custard—fold gently to keep the right texture.
Can I make a cheesy hashbrown casserole vegetarian?
Yes! Just swap sausage for your favorite diced veggies or meatless sausage and use veggie-friendly cheese options.
