☝️ See how the top of the whisked eggs have a foamy/frothy top? Those are air pockets from vigorous whisking and will give you extra fluffy eggs, especially if baked right away.

Make-Ahead Method

  • Assemble casserole as instructed, but wait on adding the frozen tater tots until just before baking.
  • Cover and refrigerate for up to 2 days.
  • Let it sit out for 10 minutes prior to baking.

Freezing Unbaked Breakfast Casserole

Yes, this is possible!

  • Assemble the casserole (except for the tater tots). Cover tightly with foil, and freeze for up to 2 months.
  • Let it defrost in the fridge overnight.
  • Let it sit out for 10 minutes. Top with Tater Tots and bake!

Storing Leftovers

  • Leftovers should be stored in an airtight container in the fridge and are best if eaten within 3 days. 
  • Reheat leftovers in a 350° oven until heated through, about 20-25 minutes.
  • You can also freeze leftovers for 3-4 months. I like wrap portion sizes in foil and store them in a labeled freezer bag.
  • Let frozen leftovers thaw in the fridge overnight prior to reheating in the oven.

A Fun Way to Use up Leftovers

  • Reheat, scramble it up a bit, and load up a flour tortilla for breakfast burritos!

This Tater Tot Breakfast Casserole has super creamy eggs, bacon and 2 kinds of cheese! It's easy to make ahead of time and is perfectly freezer-friendly!

Ingredients

  • 5 strips bacon
  • 1/2 cup white onion, diced
  • ½ cup green bell pepper, diced
  • Salt/Pepper, to taste
  • 9 large eggs
  • ¼ cup sour cream, at room temp
  • ½ cup milk
  • ½ teaspoon cayenne pepper
  • 1/3 cup feta
  • 1 cup Cheddar cheese, shredded
  • 3 cups frozen tater tots

To Garnish

  • 3 green onions, diced

Instructions

  • Preheat the oven to 375 degrees F.
  • Cook the bacon in a large skillet over low heat until crispy on each side.
  • Set the bacon aside. Once cool enough to handle, roughly chop it.
  • Reserve 1 Tablespoon of the bacon grease in the pan and drain the rest.
  • Heat the onions and peppers in the bacon drippings for 3 minutes over medium heat. Season lightly with salt and pepper.
  • Crack the eggs in a large bowl. Whisk vigorously with a fork or whisk to create a foamy consistency. These are air pockets that make the eggs fluffy.
  • Beat in the sour cream and milk until well-incorporated. Season with salt, pepper, and cayenne pepper.
  • Pour the egg mixture into a lightly greased 9 x 13 casserole dish.
  • Sprinkle the feta over the eggs, then the bacon, onions, and peppers. Note: You may want to reserve a little bit of bacon to garnish the top of the casserole with.
  • Top with grated cheddar, then with the tater tots.
  • Bake uncovered for 40 minutes, until the tater tots are crisp.
  • Let it sit for 5 minutes.
  • Top with diced green onions, serve, and enjoy!

Notes

I love using Cabot Hot Habanero Cheddar Cheese on top of this casserole and recommend it if you like a little kick!
The Tater Tots will sink into the egg mixture slightly, (this is fine!)- I like to position some tater tots on top of others so that they peek through the top without sinking down!

Optional Additional Ingredients Include:

  • Mushrooms
  • Spinach
  • Cherry Tomatoes
  • Sun-Dried Tomatoes
  • Caramelized Onions
  • Gruyere, Mozzarella, or Gouda Cheese
