A cheesy, bacon-filled breakfast casserole that you prep the night before and bake in the morning for a hearty, hands-off meal perfect for busy days.

Ingredients

Scale
  • 4 cups frozen shredded hashbrowns (about 600g / 21 oz)
  • 8 slices thick-cut bacon, cooked and crumbled
  • 2 cups shredded sharp cheddar cheese (about 200g / 7 oz)
  • 6 large eggs, room temperature
  • 1 cup whole milk (240ml / 8 fl oz)
  • 4 oz cream cheese, softened (115g)
  • 1 tsp onion powder
  • 1/2 tsp garlic powder
  • 1 tsp salt
  • 1/2 tsp freshly cracked black pepper
  • 2 tbsp fresh chives or green onions, chopped (optional)

Instructions

  1. Cook the bacon in a skillet over medium heat until crispy, about 10-15 minutes. Drain on paper towels and crumble into bite-sized pieces.
  2. Preheat oven to 350°F (175°C).
  3. In a large bowl, whisk together eggs, milk, softened cream cheese, salt, pepper, garlic powder, and onion powder until smooth. Warm cream cheese slightly if needed to melt.
  4. Add frozen hashbrowns, crumbled bacon, and shredded cheddar cheese to the wet mixture. Stir gently to combine evenly.
  5. Pour mixture into a greased 9×13-inch baking dish and spread evenly with a spatula.
  6. Cover tightly with aluminum foil or a lid and refrigerate overnight (at least 6 hours).
  7. The next morning, bake covered at 350°F (175°C) for 45 minutes. Remove foil and bake an additional 15-25 minutes until the top is golden brown and bubbly and the center is set but moist.
  8. Let the casserole rest for 5 minutes before slicing. Garnish with fresh chives or green onions if desired.

Notes

Do not thaw hashbrowns before mixing to avoid mushiness. Use room temperature eggs for smooth mixing. Cover casserole while baking to keep moist and prevent over-browning. Prep can be done up to 24 hours ahead. Leftover casserole can be refrigerated for up to 3 days or frozen for up to 2 months.
