  • 1 lb . thick-cut bacon
  • 1 T. butter
  • 1 white onion diced
  • 1 green pepper chopped
  • 1 red pepper chopped
  • 30 oz . package frozen hash browns thawed
  • 1 tsp . salt
  • 1 tsp . pepper
  • 12 large eggs
  • 1 1/2 c . milk
  • 1 T. chipotle hot sauce
  • 2 c . shredded cheddar cheese


  • Preheat oven to 400 Line a large rimmed sheet pan with parchment paper.
  • Lay bacon on lined pan so that it's close but isn't touching.
  • Bake for about 10 minutes or until tender-crisp. You don't want it to be crisp because it's going to bake longer when the casserole cooks.
  • Let bacon cool on baking sheet.
  • Remove to a paper towel-lined plate to absorb any extra grease.
  • To make the casserole, heat butter in a large skillet.
  • Add diced onion and peppers.
  • Cook until onion is translucent and peppers have softened.
  • Grease a deep 9x13-inch baking dish.
  • Layer hashbrowns and cooked veggies.
  • Season with salt and pepper.
  • Crumble cooked bacon over the top of the veggies.
  • Top with 1 cup cheese.
  • In a large bowl, whisk together eggs, milk, and hot sauce.
  • Pour over hash brown mixture.
  • Top with remaining cup of cheddar cheese.
  • Cover pan with aluminum foil, and place in the fridge overnight.
  • In the morning, get casserole out of the fridge about 30 minutes before you want to bake it.
  • Preheat oven to 400 F.
  • Bake casserole, covered, for about 45 minutes.
  • Uncover, and continue cooking for about 15 minutes longer, or until casserole is set and has baked through.
  • I like to serve this with additional chipotle hot sauce or salsa.
