  • Frozen Tater Tots: To top it all off, add frozen tater tots right from the bag onto the top of the casserole!

Here’s How to Make It

Step by Step Instructions

final four steps of preparing tater tot breakfast casserole
  1. Preheat & Prep: Preheat the oven to 350. In a large bowl, whisk together the eggs, milk, and a generous pinch of salt and pepper. Set aside.
  2. Sauté Onions & Peppers: In a large skillet or frying pan, heat the oil over a medium high heat. Add the onion and bell peppers with a pinch of salt, and cook until the pepper has started to soften and the onion has started to color, about 5 minutes.
  3. Brown the Sausage: Add the ground sausage and continue to cook, breaking it up with the back of your spoon until the sausage is cooked through and browned slightly. Stir the cooked sausage mixture into the egg mixture along with half of the cheese.
  4. Sauté Mushrooms: Next, wipe out the pan with a piece of paper towel before returning it to the heat and melting the butter. Add the mushrooms with a little more salt and pepper and cook until soft and slightly browned. Stir in the heavy cream and season to taste before removing it from the heat.
  5. Assemble: Butter a large baking dish or prepare it with cooking spray. Pour in the egg mixture and spoon the mushroom mixture over the top. With the spoon, swirl the mushroom mixture slightly into the egg mixture so they’re combined in places, but still separate.
  6. Add Tater Tots & Bake: Arrange the frozen tater tots on top and sprinkle over the rest of the cheese. Bake for 50 minutes until the cheese has melted and the tops of the tater tots are golden.

Expert Tips

  • Add some more veggies! You can really pack this one with more veggies of your choice like tomatoes, broccoli or spinach!
  • Watch the cooking time. Make sure to keep an eye on the casserole and don’t over bake! The eggs are going to be pretty moist due to the milk and heavy cream, but you don’t want them to be over baked. Once the tater tots are done cooking, the rest is good to go!
  • You can skip the breakfast sausage and add bacon instead if you prefer. Or, for a healthier option try chicken sausage!
  • Does you family love brinner? This is a great breakfast for dinner idea that the whole family will love!

Frequently Asked Questions

Can I freeze tater tot breakfast casserole?

Definitely! After baking and cooling to room temperature, you can cover the top of the baking dish well in plastic wrap, using a few layers if necessary. Then add a layer of aluminum foil to prevent against freezer burn. When you are ready to eat it, let it thaw slowly overnight in the fridge and then pop it in the oven to reheat the next morning!

This breakfast casserole will last in an airtight container in the fridge for up to 6 days. To reheat, you can pop it in the microwave but we recommend putting it until the broil for a minute or so to make it nice and toasty on the top again!
