How to Make Sweet Potato Hashbrown Breakfast Casserole
Step 1: Preheat and Prepare Your Baking Dish
Start by preheating your oven to 375°F (190°C)—this way, it’s perfectly hot when your casserole is ready to go in. Lightly grease a 9×13-inch baking dish with cooking spray or a drizzle of oil so nothing sticks, and you get those lovely, clean slices.
Step 2: Sauté the Vegetables
Heat the olive oil in a large skillet over medium heat. Once shimmering, add your diced onion along with the red and green bell peppers. Cook these for 4 to 5 minutes until the onions turn translucent and the peppers soften, stirring occasionally to prevent sticking. Toss in the chopped spinach and cook just until wilted—about a minute—then remove everything from the heat.
Step 3: Whisk the Egg Mixture
In a spacious mixing bowl, crack in all eight eggs and pour in the milk. Sprinkle in the garlic powder, smoked paprika, salt, and black pepper. Whisk until the yolks, whites, and seasonings are fully combined and the mixture takes on a silky consistency.
Step 4: Combine Everything
Fold the shredded sweet potatoes into the egg mixture, mixing well to break up clumps. Next, add in the sautéed veggies and scatter in half of the shredded cheddar cheese, ensuring each ingredient is evenly distributed. This is the moment where everything melds together—so take your time mixing!
Step 5: Assemble and Bake
Pour the combined mixture into your prepared baking dish, smoothing out the top with a spatula for even cooking. Sprinkle the remaining cheddar cheese across the surface so every slice ends up with gooey, golden topping. Slide the dish into the oven and bake for 35 to 40 minutes, or until the center is firmly set and the top is gloriously golden brown.
Step 6: Cool, Slice, and Serve
Once baked, let your Sweet Potato Hashbrown Breakfast Casserole cool for a few minutes—this will make for neater slices and allow the flavors to settle. Use a sharp knife or spatula to portion out slices, then serve warm to savor all those creamy, cheesy, and veggie-packed bites!
How to Serve Sweet Potato Hashbrown Breakfast Casserole

Garnishes
Amp up each serving with a flourish of fresh chopped herbs—think parsley, chives, or even a sprinkle of dill. If you’re a fan of spice, a dash of hot sauce or a scattering of red pepper flakes takes things up a notch. A spoonful of tangy Greek yogurt or sour cream on the side is always a crowd-pleaser.
Side Dishes
Pair your Sweet Potato Hashbrown Breakfast Casserole with a simple fruit salad for refreshing balance, or some toasted sourdough to mop up every tasty bit. If you’re aiming for a heartier brunch, crispy bacon or breakfast sausage are classic companions.
Creative Ways to Present
For a charming brunch buffet, cut the casserole into bite-sized squares and stack them on a platter—it’s always a hit at gatherings! You can also layer slices into toasted English muffins or wraps for an on-the-go breakfast sandwich, turning leftovers into a lunchtime upgrade.
Make Ahead and Storage
Storing Leftovers
Leftover Sweet Potato Hashbrown Breakfast Casserole keeps beautifully in the fridge! Simply transfer slices to an airtight container and refrigerate for up to four days. It’s a meal prep dream—ready for busy mornings or an easy lunch.
Freezing
If you want to stash some away, let the casserole cool completely, then cut into portions. Individually wrap each slice in foil or plastic wrap, and pop them into a freezer bag or container. They’ll be good for up to two months, making breakfast totally effortless.
Reheating
To reheat, unwrap and microwave a slice for 1 to 2 minutes, or place it in a 350°F oven until warmed through—about 10 minutes. The casserole stays creamy and flavorful, so every bite tastes just as good as when it was first baked.
