Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- In a large mixing bowl, combine the thawed and squeezed-dry hashbrowns with melted butter, garlic powder, onion powder, 1/2 tsp salt, and 1/4 tsp black pepper. Mix until the hashbrowns are evenly coated.
- Press the seasoned hashbrown mixture evenly into the bottom of the prepared baking dish. Bake for 20 minutes, or until the edges start to crisp and turn golden. This step helps ensure a crispy base for your Hashbrown Breakfast Casserole.
- While the hashbrowns are baking, cook the breakfast sausage in a large skillet over medium heat, breaking it up with a spoon until fully browned. Drain any excess grease and set aside.
- In a medium mixing bowl, whisk together the eggs, milk, 1/2 tsp salt, 1/4 tsp black pepper, and optional red pepper flakes until well combined.
- Remove the baking dish with the hashbrowns from the oven. Sprinkle the cooked sausage evenly over the hashbrown layer. Top with half of the shredded cheddar cheese and half of the Monterey Jack cheese.
- Pour the egg mixture carefully and evenly over the sausage and cheese layers.
- Sprinkle the remaining cheddar and Monterey Jack cheeses over the top of the casserole.
- Cover the baking dish loosely with aluminum foil and bake for 30 minutes. Remove the foil and continue baking for another 20-25 minutes, or until the eggs are set and the top is golden brown and bubbly.
- Let the Hashbrown Breakfast Casserole rest for 5-10 minutes before slicing and serving. This allows the casserole to set further.
Notes
Creating the perfect Hashbrown Breakfast Casserole is all about a few simple steps that make a big difference. These are the little tricks I’ve picked up over the years that ensure every bite is as delicious as possible.
- Crispy Hashbrowns are Key: Don’t rush the initial baking of the hashbrown base. Getting them golden and slightly crispy before adding the other layers prevents a soggy bottom and provides a fantastic textural contrast in your finished casserole. I always spread them out evenly for even cooking.
- Don’t Overcook the Sausage: Cook the breakfast sausage just until browned, then drain any excess fat. This keeps the casserole from becoming greasy and allows the savory sausage flavor to shine without overpowering the other ingredients in our Hashbrown Breakfast Casserole.
- My Secret Trick: I always let the assembled casserole sit for about 15-20 minutes at room temperature before baking, especially if I’m making it ahead. This allows the egg mixture to slightly absorb into the hashbrowns and sausage, resulting in a more cohesive and tender casserole with even cooking.
- Embrace the Make-Ahead Magic: This casserole truly shines as a make-ahead dish! Assemble everything the night before, cover it tightly, and pop it in the fridge. In the morning, just take it out about 30 minutes before baking to let it come closer to room temperature, then bake as directed. It’s a game-changer for stress-free mornings!
Fun Variations for Hashbrown Breakfast Casserole
One of the things I adore most about a good Hashbrown Breakfast Casserole is how wonderfully versatile it is. It’s like a blank canvas waiting for your creative touch! Here are a few ways my friends and I love to change things up:
Veggie Boost
For a delicious and colorful addition, sauté some diced bell peppers, spinach, or mushrooms with your breakfast sausage. My friend Sarah always asks me to add a medley of colorful peppers and onions; it gives the casserole a lovely sweetness and extra nutrition.
Spice It Up!
If you love a little kick, consider adding a pinch more red pepper flakes to your egg mixture, or even a dash of hot sauce. For a smoky flavor, a sprinkle of smoked paprika is a wonderful choice.
Cheese Please!
While cheddar and Monterey Jack are a classic pairing, feel free to experiment with other cheeses. Pepper Jack can add a nice zing, or a touch of smoked gouda could introduce a sophisticated depth of flavor. My cousin loves when I swap in a bit of sharp provolone for extra tang.
Protein Power
Instead of breakfast sausage, you could use diced ham, cooked bacon, or even crumbled chorizo for a different flavor profile. Some mornings, I’ll even mix in a bit of leftover shredded chicken for an unexpected twist!
What to Serve With Hashbrown Breakfast Casserole
Our delightful Hashbrown Breakfast Casserole is a hearty meal in itself, but a few simple additions can truly complete the brunch experience. I always think about balancing the richness with something fresh and bright.
I love serving this casserole with a fresh fruit salad, bursting with seasonal berries and melon; the juicy sweetness is a perfect contrast. A side of warm, buttered toast or flaky biscuits is also always a welcome sight, perfect for soaking up any last bits of cheesy goodness. For drinks, a hot cup of freshly brewed coffee or a tall glass of orange juice rounds out the meal beautifully. My mom always pairs this with her homemade mimosa recipe when we have a special occasion, which adds a lovely celebratory touch!
How to Store Hashbrown Breakfast Casserole
Knowing how to properly store your Hashbrown Breakfast Casserole means you can enjoy those comforting flavors for days to come, or even pull it out for a quick meal when you need it most!
Fridge Storage
Once the casserole has cooled completely, cover it tightly with plastic wrap or transfer individual portions to airtight containers. It will keep beautifully in the refrigerator for 3-4 days. This makes it perfect for meal prepping!
Freezer Tips
For longer storage, cut the cooled casserole into individual servings. Wrap each piece tightly in plastic wrap, then place them in a freezer-safe bag or container. It can be frozen for up to 2-3 months. When I freeze leftovers, I like to label each portion with the date so I know exactly how long it’s been stored.
Reheating Methods
From the fridge, you can reheat individual slices in the microwave until warmed through. For a crispier edge, pop slices into a toaster oven. If reheating a whole casserole from the fridge, cover it loosely with foil and bake at 300°F (150°C) until hot. From frozen, thaw overnight in the fridge before reheating, or reheat gently from frozen in the oven, covered, at a lower temperature until warmed through, removing the foil for the last few minutes to crisp up.
Nutritional Benefits
This comforting casserole isn’t just delicious; our Hashbrown Breakfast Casserole also offers some satisfying nutritional benefits. With protein-rich eggs and breakfast sausage, it provides a great start to your day, keeping you feeling full and energized. The cheeses contribute calcium, while the humble hashbrowns offer some good energy to fuel your morning. It’s a treat that’s both satisfying and nourishing, embodying my philosophy of making hearty food with simple ingredients.
FAQs
Faq 1
Can I assemble this Hashbrown Breakfast Casserole the night before?
Absolutely! This casserole is designed to be make-ahead friendly. Assemble it fully, cover tightly with plastic wrap, and refrigerate overnight. Just remember to take it out about 30 minutes before baking to let it come closer to room temperature.
Faq 2
How can I prevent my casserole from being watery?
To avoid a watery casserole, ensure your breakfast sausage is thoroughly drained of excess grease after cooking. Also, make sure your hashbrowns are mostly thawed and patted dry if they have a lot of ice crystals, as this helps maintain a perfect texture for your Hashbrown Breakfast Casserole.
Faq 3
What kind of milk should I use for the egg mixture?
I recommend using whole milk for a richer, creamier egg mixture that truly enhances the flavor and texture of your Hashbrown Breakfast Casserole. However, 2% milk can also work well if you prefer a slightly lighter option without sacrificing too much richness.
Faq 4
Can I add vegetables to this breakfast casserole?
Yes, definitely! Diced bell peppers, onions, spinach, or mushrooms are wonderful additions. Sauté them with the sausage or hashbrowns before assembling to ensure they are tender and cooked through, adding extra flavor and nutrition to your Hashbrown Breakfast Casserole.
