I am most definitely a savory breakfast person. As delicious as french toast and doughnuts are, they just don’t keep me satisfied for very long. I almost always have eggs for breakfast, and this easy breakfast casserole with bacon is the perfect way to feed an egg loving crowd!

This casserole is chock full of eggs, potato tots, crumbled bacon and cheddar cheese. The finishing touch is a fresh and delicious avocado and tomato topping, which cuts through the richness of the casserole. Plus who couldn’t use a few veggies in the morning?!

Breakfast Casserole With Bacon Ingredients

To make this recipe, you will need bacon, frozen tater tots, eggs, cheddar cheese, milk, salt, black pepper, tomatoes, avocado and chives.

How Do You Make Breakfast Casserole With Bacon?

Preheat the oven and coat a casserole dish with cooking spray. Place the frozen potato tots in a single layer at the bottom of the baking dish. Place the eggs and milk in a large bowl, and whisk to combine. Stir most of the bacon into the eggs and half of the cheese, then season with salt and pepper to taste. Pour the egg mixture over the potatoes, then add the rest of the bacon and cheese on top of the casserole. Bake until the eggs have set. Stir together the tomatoes, avocado, chives and salt. Add the vegetable mixture on top of the casserole, then cut into squares and serve.

Tips For The Perfect Dish

  • You do not need to thaw your potato tots before you put them in the casserole.
  • I recommend grating your own cheddar cheese. Store bought shredded cheese contains preservatives and anti caking agents and does not melt as well.
  • You can prepare this casserole the night before. Store it covered in the fridge for up to 8 hours, then bake according to the recipe. You’ll want to make the tomato topping right before serving.
  • Leftovers will stay fresh in an airtight container in the refrigerator for up to 4 days. You can microwave individual slices to warm them.

Quick Tip

There’s no need to add a lot of extra salt to the casserole, since the bacon, eggs and potato tots all contain salt.

Recipe FAQs

How do you know when breakfast casserole is done?

A breakfast casserole is done when the top is golden brown, and a skewer inserted into the middle comes out clean, or with a few moist crumbs attached. If the skewer has liquid on it, it means the eggs are not cooked and it needs more time.

Do you bake a casserole covered or uncovered?

You should bake your egg casserole uncovered. If you feel that the top is getting overly browned before the inside is done, you can place a sheet of foil on top of the casserole partway through the baking process.


Flavor Variations

While this dish is delicious as-is, you can add other ingredients to customize the flavors to your tastes.

  • Meat: You can substitute cooked sausage or ham for the bacon.
  • Cheese: No cheddar on hand? This recipe also works well with mozzarella, gouda, swiss or fontina cheese.
  • Potatoes: Swap out the tater tots for other frozen potatoes such as hash browns or diced potatoes.
  • Vegetables: Feel free to add up to 1 cup of cooked vegetables to the casserole. Some great onions include bell peppers, green onions, mushrooms or spinach.

This breakfast casserole recipe is the perfect choice for a holiday meal, or you can make it at the beginning of the week and reheat a square each day for a quick breakfast on the go. My family has started requesting this one almost every weekend, it’s just that good!

  1. Can I make this a day before then heat it in the morning? I’d assume the potatoes would be thawed by the time I heat it.

  2. 5 stars
    It didn’t look like enough tater tots so I covered the whole bottom of the pan. BIG mistake! LOL It was still very good – but waaaaay too potato-y! Next time I will only use the 16 oz bag!!

  3. 5 stars
    Love this ! It is so easy and versatile. You can add veggies in, too!
    Has anyone tried microwaving leftovers? How did it go?

    1. Yes!! We microwaved our leftovers for like 3 days after Christmas (bc this is my go to Christmas breakfast dish bc the whole family is obsessed with it!!) and it was just as good as the day I baked it😉

  4. Hello – can this be made and frozen BEFORE cooking, then thawed and cooked so “freshly cooked”, instead of cooked, frozen and reheated? Thank you

      I used Hormel bacon bits and it was delicious! I don’t “do” bacon, so was glad to have that option!

      A 16 oz bag of frozen tater tots. Don’t be tempted to use more – I know it doesn’t look like much in the pan, but I put more and the potato took over the casserole!

    We enjoyed this for a brunch I made! I prepared it earlier then just had to pop it in the oven right before my guests came. It seemed like everyone asked for seconds!

    Thank you for the recipe! I made the casserole for a Easter brunch and it was a big hit! I used low sodium sausage and no one couldn’t even tell. Yummy!!!

    Thank you for this recipe! My boyfriend can’t have fodmaps so my go-to breakfast casserole with sausage and bread is no longer a breakfast option. We have made this a few times now, including taking to his family on Christmas morning. It was a big hit! It comes together so quickly and has a great flavor! It’s now in our regular rotation… to the point I created a note on my phone so I always have the ingredients with me 🙂

  8. 4 stars
    None of the comments here are very useful. That being said – the flavor of this casserole is very good! BUT – the eggs kind of disappeared. Next time I’ll add 6 more eggs and it will be divine! Best casserole ever.
