The Best Breakfast Casserole Recipe {VIDEO}

This is the tastiest breakfast casserole recipe you’ll find! Super easy and delicious breakfast casserole made with tater tots, veggies, sausage and cheese. Great breakfast to make for guests and can be prepped ahead of time.

Best Breakfast Casserol

This breakfast casserole is my favorite easy breakfast of all time. Did you hear that? ALL TIME! I started making this yummy breakfast a couple decades ago (whoa) and mainly for those times when I had guests overnight and wanted to feed them heartily in the morning. This is a great prep-ahead meal (leave out the tots till just before baking) and I am telling you, it gets rave reviews and it gets devoured every single time. Prep is minimal and I love the extra yum that the tater tots provide.

Do you bake breakfast casserole covered or uncovered?

If you are storing this casserole in the fridge overnight, cover it with foil. For baking, though, you can remove the foil. If for some reason you find that your cheese is getting too crispy (this has never happened to me with this recipe), loosely cover with foil for the remainder of the cook time.

How long can you refrigerate breakfast casserole?

One of the things I love about this dish is that it is a great prep-ahead and bake later option. Cover and store in the refrigerator for up to 36 hours before baking. After the casserole has baked, it can be kept in the fridge for 3 days and still taste fresh and delish.

Notes about this Breakfast Casserole:

  • Replace sausage with a leaner meat if desired, but the sausage adds incredible flavor to the dish!

  • Use whichever color bell pepper you’d like!

  • Add up to 1 cup extra of veggies for added flavors and textures.

Super easy breakfast casserole made with tater tots, veggies, sausage and cheese. Great breakfast to make for guests and can be prepped ahead of time.


  • 1 pound ground pork breakfast sausage
  • 1 bell pepper, seeded and chopped
  • 1 yellow onion, chopped
  • 8-oz. package fresh sliced mushrooms
  • 12 eggs
  • 10.75-oz. can cream of mushroom soup
  • 1 1/4 cups milk
  • 2 cups shredded cheddar cheese, divided
  • 32-oz. package frozen potato rounds (aka, tater tots!)


  1. In a large skillet, cook sausage over medium heat until almost cooked through. Add bell pepper, onion and mushrooms to the skillet and cook till the veggies are tender and meat is cooked all the way through, about 5 minutes. Drain the grease and set aside.
  2. Preheat oven to 350 degrees F and coat a 9x13 baking dish with cooking spray. In a large bowl, beat together eggs, cream of mushroom soup, milk and 1 cup of the cheese. Add the sausage-veggies mixture and mix well. Pour contents into prepared the baking dish. Drop in the tater tots. (If prepping the night before, leave out the tater tots until just before baking.)
  3. Bake uncovered in the preheated oven for 55 minutes. Sprinkle with the remaining 1 cup of cheese and bake an additional 10-15 minutes, or until cheese is melted and eggs are cooked through. Let sit for 10 minutes before serving.
