How to Make a Breakfast Casserole

This breakfast casserole recipe is the BEST because of how simple it comes together and is in the oven in just minutes. This tried and true breakfast casserole tastes amazing, and I know your whole family will love it!

  1. Prepare Frozen Hash Browns: Spray a 13 x 9 x 2-inch baking dish with non-stick cooking spray. Add the frozen shredded hash browns to the bottom of the prepared pan. Season with salt and pepper.
  2. Whisk Eggs/ Add Remaining Ingredients: In a large bowl, whisk the eggs. Add the half and half and seasoned salt, then whisk to combine. Stir in the shredded cheese and chopped ham.
  3. Pour Into Pan and Refrigerate: Pour over the top of the frozen hash browns, then cover with foil and refrigerate for 2 hours or overnight.
  4. Bake: Bake uncovered at 350 degrees Fahrenheit for 60-75 minutes. Let rest for 10 minutes before serving.

Mix It Up!

Try some of these fun variations in this breakfast casserole and find what you enjoy best!

  • Can I add vegetables?  Add in some veggies like bell peppers, spinach or kale, tomato (fresh or canned), broccoli, mushrooms, or onions are great.
  • Do I have to use ham? You can use bacon, variations of sausage, shredded chicken, ground beef, or leftover turkey.
  • Do I have to use Half & Half? If you’re not a fan of half and half, you can use whipping cream for a thicker, richer breakfast, or you can simply use milk.
  • Can I use any kind of cheese? Switch up which cheese you use. Try Swiss cheese, Colby jack, or mozzarella, which all work well and melt perfectly when baked.
  • How can I make this spicy? Adding red pepper flakes, green chilies, or green onions is a fun way to add a little heat.
  • Can I use different potatoes? Diced or flavorful frozen potatoes will work great in place of shredded potatoes.

Tips for Making Breakfast Casserole

Here are some tips for making this breakfast casserole even better and easier on you. These tips will help you better understand how to bake this breakfast for you to enjoy with your family.

  • Do I Need to Thaw the Frozen Hash Browns? There is no need to thaw the potatoes because they will thaw as they sit in the refrigerator. However, they would cook up perfectly if they were to cook from frozen!
  • How Do I Know When the Casserole is Done? Once the outside edges become golden brown and the egg mixture in the middle is firm. You can check by slightly shaking the pan to see if it jiggles. Use a toothpick or knife to check if it is completely cooked through the middle. You can also use a thermometer to see if the breakfast casserole has reached 165 degrees Fahrenheit.
  • Short on Time? Allowing your casserole to refrigerate ahead of time creates the best results, and I highly recommend it! But if you’re short on time, you can assemble the casserole and bake it right away without refrigerating.
  • Drain Grease: If you use any other meat in the breakfast casserole, drain the meat before adding it to the dish.

Storing Breakfast Casserole

There are so many options and plans for this breakfast casserole to make your holiday mornings even easier and better.

  • In the Refrigerator: Store leftovers in an airtight container in the refrigerator for 3-5 days.
  • To Reheat: To reheat the breakfast casserole, microwave individual servings until warmed through.
  • In the Freezer: Yes, this is perfect for freezing. Make and bake your breakfast casserole. Once it has completely cooled down, place it in an airtight container or ziplock bag. Lay flat in your freezer for up to 1 month. Thaw from frozen in the refrigerator over night. Warm individual servings in the microwave until warmed through.
  • Make Ahead Instructions: Simply follow the instructions until you are ready to bake. Cover it with aluminum foil or a lid and place it in your fridge. When you are ready to bake, simply take it out and bake it according to the instructions. This can sit in the fridge for up to 2 days before baking.

  1. No sure how it tastes yet but still cooking after 1 hr and 45 mins middle is complete liquid still followed recipe to the T and now flipped on broil and trying to scramble in the Pyrex.

    1. that’s crazy because i pulled mine out ten minutes early and it was so overdone is was just moments from being completely inedible.

  2. I don’t have any hash browns or potatoes, can I just omit them and how would that affect the cook time?

    1. The hash brows are necessary and act as a base to hold the entire casserole together. I wouldn’t skip that ingredient.

  3. Do you think this would turn out with a dairy free milk like almond? My daughter can’t have dairy.

  4. 5 stars
    This is so yummy! Always a big hit when we have guests- i want to try adding onions next time. Do you think they’ll hold up when cooking?

    1. It doesn’t need to be refrigerated before baking but make sure to store any leftovers in your fridge in an airtight container!

      1. If it doesn’t need to be refrigerated for at least 2 hours, why is that in the recipe instructions? I’ve found when I follow this recipe and refrigerate overnight, it takes much longer to bake. I would prefer to mix everything and bake immediately.

      2. Hi, this recipe does need to be refrigerated for at least 2 hours before baking!

      1. I would decrease it by a few minutes and keep an eye on it. Are you planning on baking it in an 8×8 dish?

  5. 5 stars
    This recipe is terrific 🤍. I found the 1-1/2 hour cooking time to be perfect when covered with foil….it allows the egg mixture to percolate, creating tiny bubbles and allowing the mixture to rise to a more soufflé consistency. Thank yo Alyssa!
