Easy Egg Hashbrown Breakfast Casserole

There’s something oddly comforting about the smell of crispy hashbrowns mingling with baked eggs in the morning. This breakfast casserole isn’t one of those fancy dishes that tries too hard—it’s the kind that reminds you of slow weekends, coffee in hand, and the sound of bacon sizzling somewhere nearby. I love it because it’s hearty without being fussy, the kind of recipe you can toss together when everyone wakes up hungry and you haven’t even had your first sip of caffeine yet. The eggs bake up fluffy, the cheese melts into those golden potatoes, and every bite feels like a little morning hug. It’s one of those egg casserole recipes that just works—every single time. Whether you’re feeding a crowd or meal-prepping for the week, this Vegan Breakfast Casserole (yes, it can be made plant-based too) adapts beautifully. Add veggies, sausage, or that forgotten bit of spinach from the fridge, and suddenly you’ve got the best casserole recipe on your table. I’ve made this Breakfast Casserole With Bisquick before, and while it’s fun for a change, this version keeps things simple. If you like egg casserole recipes easy enough for a half-asleep Sunday, this one’s for you. No stress, no fancy gadgets—just a whisk, a casserole dish, and your oven doing the heavy lifting. It’s the kind of recipe for breakfast that makes you feel like you’ve got your life together—even if your hair says otherwise.

Ingredients

  • 6 large eggs
  • 1 (20-ounce) bag frozen hash browns, thawed

  • 1/2 cup diced bell pepper
  • 1 cup cooked bacon or sausage (optional)
  • 1 cup milk
  • Salt and black pepper to taste
  • Butter or oil for greasing the baking dish

Instructions

  1. Preheat your oven to 375°F and grease a 9x13-inch baking dish.
  2. In a large bowl, whisk the eggs and milk together until smooth.
  3. Add the thawed hash browns, cheese, onion, bell pepper, and cooked bacon or sausage if using.
  4. Season generously with salt and black pepper, then mix everything until well combined.
  5. Pour the mixture into the prepared baking dish and spread it evenly.
  6. Bake for 40–45 minutes or until the eggs are set and the top is lightly golden.
  7. Let it rest for a few minutes before cutting—if you can wait that long. Serve warm.
