Ingredients
  

Main Ingredients

  • 1 bag frozen hash browns (about 20–30 oz) Thaw or lightly drain if needed.
  • 1 cup shredded cheddar cheese Use sharp or medium for flavor.
  • 1 cup shredded mozzarella cheese For melt and gooiness.
  • 6 large eggs Whisked with milk and seasonings.
  • 1 cup milk (whole or 2%) For creaminess.
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup diced bell peppers Any color.
  • 1 cup diced cooked turkey bacon Can substitute with cooked pork bacon, ham, or cooked sausage.

Instructions
 

Preparation

  • Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish or spray with nonstick oil.
  • If the hash browns are clumped, break them up in the bag or bowl. Spread the frozen (or partly thawed) hash browns evenly in the prepared baking dish.
  • Scatter the diced bell peppers and cooked turkey bacon over the potatoes. Sprinkle half of both cheeses evenly on top.
  • In a medium bowl, whisk the eggs, milk, garlic powder, onion powder, salt, and black pepper until smooth and slightly frothy.
  • Pour the egg mixture evenly over the potato, pepper, and bacon layer. Press down gently so the liquid reaches the potatoes.
  • Top with the remaining cheddar and mozzarella.

Baking

  • Bake uncovered for 40–50 minutes, or until the center is set (no runny egg) and the top is golden brown.
  • If the top browns too quickly, tent with foil for the last 10–15 minutes.
  • Let the casserole rest for 10 minutes before slicing.

Notes

For richer custard, swap half the milk for half-and-half. For dairy-free, use unsweetened plant milk and a dairy-free cheese alternative. You can add veggies like spinach or mushrooms for extra flavor.
