Ingredients
Tater tot breakfast casserole calls for easy to find ingredients! Here’s what you’ll need:
![ingredients for tater tot breakfast caserole](https://www.lecremedelacrumb.com/wp-content/uploads/2023/03/tater-tot-breakfast-casserole-ingredients-10-scaled.jpg)
- Eggs & Milk: I combine eggs and milk for a super fluffy egg base!
- Onion: Sautรฉing the onion is the first step in starting to build lots of flavor.
- Red & Green Bell Pepper: Red and green bell pepper are added for flavor and the addition of some fresh veggies!
- Ground Breakfast Sausage: It is easiest to add ground breakfast sausage that is already seasoned here and it is generally easy to find at your local grocery store!
- Shredded Cheese: I like added shredded cheddar cheese, but you can use your favorite kind of shredded cheese.
- Mushrooms: Slice your mushrooms however big or small you would like!
- Heavy Cream: Heavy cream is added to the mushrooms to create a creamy and moist layer.
- 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
- 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. (photo 1)
- Sautรฉ 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. (photo 2)
- 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. (photos 3-4)
- Sautรฉ 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. (photos 5-6)
- 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. (photos 7-8)
- 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. (photos 9-10)
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
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!

Great recipe. This sounds delicious and easy to try. which is awesome for my healthy weekday meals.
I made this one night before bed, so excited to wake up to a yummy breakfast!
Unfortunately I woke up to a nasty soup looking casserole! Not sure what I did wrong, I didn’t use the seasoning packet, and I used a whole bag of Tator tots, and two dozen eggs.
Hi Mandy,

Now in our regular Rotation. Family loves this!
I love hearing when a recipe becomes a regular rotated one for a family- thanks so much, Jessica!
Hi! Looks like the MCCORMICK SEASONING HAS BEEN DISCONTINUED! WHAT WOULD YOU SUGGEST AS A SUB? THANKS!
Hi Claudia! I am not positive on a substation at this time- I will let you know if I come up with one when I make this next!
A really tasty seasoning mix for eggs and poultry that i always keep on hand is 1 tbsp garlic powder, 1 tbsp onion powder, 1 tbsp paprika (sweet or smoked), 1 tbsp oregano or italian blend, 1 tbsp salt, 1 tbsp black pepper. Mix that up together and use 1 tbsp for your recipes, or however much to your desired taste.
This is how McCormick’s describes the seasoning packet. You can take your cue from the listed ingredients: Ultimate Egg Casserole โ Featuring onion, chili pepper and paprika, this seasoning mix
is the perfect partner for eggs, cheese and potatoes.
