Tips & Variations

  • For a vegetarian option, omit the bacon and add mushrooms or spinach instead.
  • Use your favorite cheese blend, such as cheddar and Monterey Jack, for extra flavor.
  • Make sure the eggs are well beaten to help the casserole set evenly.
  • Substitute almond or oat milk if you prefer a dairy-free version.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave until warmed through. To freeze, wrap tightly and use within 2 months; thaw overnight before reheating.

How to Serve

The image shows a cooked dish in a black pan with several layers. The bottom layer is a creamy white base, covered by a melted layer of orange-yellow cheese that is slightly browned in spots. On top of the cheese, there are small pieces of crispy bacon, light brown with some darker edges, mixed with small green slices of scallions scattered evenly across the surface. There are also small bits of green peppers visible under the cheese. The overall texture looks gooey from the cheese, crispy from the bacon, and fresh from the scallions. The pan edges are dark and glossy. The photo is taken with an iphone --ar 4:5 --v 7

FAQs

Can I use fresh potatoes instead of frozen hashbrowns?

Yes, you can use peeled and diced fresh potatoes, but be sure to par-cook them slightly before layering to ensure they cook fully overnight.

What if I don’t have a crock pot?

This casserole can also be baked in a 9×13 inch baking dish at 350°F (175°C) for about 45-55 minutes, or until the eggs are set and the top is golden brown.

  • 12 large eggs
  • 1 cup whole milk
  • 1/2 tsp salt
  • 1/2 tsp black pepper

Instructions

  1. Prepare the Crock Pot and Bacon: Spray the crock pot with a nonstick cooking spray to prevent sticking. Cook the bacon strips in a skillet over medium heat until they are crisp. Remove the bacon, chop it into pieces, and set aside.
  2. Sauté Vegetables: In the same skillet or a separate pan, sauté the chopped onion, green bell pepper, and peeled garlic clove for about 5 minutes until the vegetables are softened and fragrant.
  3. Layer Ingredients: Place one-third of the frozen hashbrowns evenly on the bottom of the crock pot.

  5. Cook the Casserole: Cover the crock pot with its lid and cook on the low setting for 8 to 10 hours. The casserole is done when a food thermometer inserted in the center reads 160 degrees Fahrenheit, indicating the eggs are fully set and cooked through.
