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
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.
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!

It’s nice to have something hearty and filling for breakfast. That’s way better than cereal on the go (and by on the go, I mean while making sure your kid ties your shoes too while you fly out of the door eating, hahaha, slight exaggeration, but only slight for our a.m. ritual). ๐
