Ingredients You’ll Need
The beauty of this Tater Tot Breakfast Casserole Recipe lies in its straightforward, pantry-friendly ingredients that each add their own magic. Every item plays a key role in delivering layers of flavor, creamy texture, or that irresistible crispy finish.
- Frozen tater tots: These provide a crunchy, golden topping that contrasts perfectly with the soft eggs beneath.
- Breakfast sausage (pork or turkey): Adds a rich, savory protein element with a hint of spice.
- Small onion, diced: Brings a subtle sweetness and depth when sautéed with sausage.
- Large eggs: The creamy base that holds everything together with a fluffy texture.
- Whole milk: Ensures a smooth, custard-like consistency for the egg mixture.
- Heavy cream: Elevates the richness and adds silkiness to the casserole.
- Shredded cheddar cheese: Melts into a gooey layer that infuses sharp flavor throughout.
- Garlic powder: Offers a subtle aromatic touch without overpowering the dish.
- Salt and black pepper: Essential for seasoning every layer perfectly.
- Chopped green onions or parsley (optional): Adds a fresh, vibrant finish when sprinkled on top.
How to Make Tater Tot Breakfast Casserole Recipe
Step 1: Prepare and Cook Sausage Mixture
Start by preheating your oven to 350°F (175°C) and lightly greasing a 9×13-inch baking dish. Next, in a large skillet over medium heat, cook your breakfast sausage along with the diced onion. Break the sausage into small pieces as it cooks to ensure even browning. Once the sausage is fully cooked and the onions are soft and fragrant, drain any excess grease to keep the casserole from becoming greasy, then set this flavorful mixture aside.
Step 2: Whisk the Egg Mixture
In a sizable mixing bowl, whisk together the eggs, whole milk, heavy cream, garlic powder, salt, and black pepper. This mixture will become the custard base that holds your casserole together, so incorporating these ingredients thoroughly will result in a creamy, tender texture after baking.
Step 3: Assemble Your Casserole Layers
Spread your cooked sausage and onion mixture evenly across the bottom of the prepared baking dish. Then sprinkle the shredded cheddar cheese over the sausage for a rich, melty layer. Pour the egg mixture carefully over the cheese, ensuring it covers everything evenly without disturbing the layers below.
Step 4: Add Tater Tots and Bake
Arrange the frozen tater tots in a single layer on top of the egg mixture—this is the crowning glory that will become perfectly crispy and golden. Bake your casserole uncovered for 45 to 50 minutes, or until the eggs are fully set and the tater tots have turned a delicious, crispy brown. Allow the casserole to rest for 5 to 10 minutes before slicing to make serving easier and to let the flavors settle.
How to Serve Tater Tot Breakfast Casserole Recipe

Garnishes
A simple sprinkle of chopped green onions or fresh parsley adds a splash of color and a burst of fresh flavor that lifts the whole dish. This optional step also gives the casserole a lovely finishing touch, making it feel extra special.
Side Dishes
Consider pairing your tater tot breakfast casserole with lightly dressed greens or a fresh fruit salad to balance the richness. A side of crispy bacon or some buttery toast rounds out the meal with extra texture and flavor variety.
Creative Ways to Present
This casserole looks wonderful served right from the baking dish for a cozy family-style breakfast, but you can also scoop individual portions into ramekins or muffin tins for personal servings. This makes it ideal for brunch parties or meal prep, and the crispy tater tot top means everyone gets a little crunch in every bite.
Make Ahead and Storage
Storing Leftovers
Cool any leftovers completely before transferring them to an airtight container in the refrigerator. Stored properly, your casserole will stay fresh for up to 3 to 4 days, making it perfect for next-day breakfast or a quick snack.
Freezing
This Tater Tot Breakfast Casserole Recipe is freezer-friendly! Wrap individual portions tightly in plastic wrap and aluminum foil, or store in freezer-safe containers. It can be frozen for up to 2 months. Thaw overnight in the fridge before reheating for the best results.
Reheating
Reheat your casserole in the oven at 350°F (175°C) for 15–20 minutes or until warmed through. For a quicker option, microwave single slices on medium power for 90 seconds to 2 minutes, although the oven reheating retains the crispiness of the tater tots best.
FAQs
Can I use a different type of cheese in the Tater Tot Breakfast Casserole Recipe?
Absolutely! Cheddar works beautifully because of its sharp flavor and meltability, but feel free to swap in mozzarella for stretchiness, pepper jack for a spicy kick, or Swiss for a milder, nutty note.
Is it okay to substitute bacon or ham for the sausage?
Yes, swapping sausage for bacon or ham can add variety and a different flavor profile. Just cook the bacon or ham thoroughly before layering it into the casserole.
Can I add vegetables to this recipe?
Definitely! Including chopped bell peppers, spinach, or mushrooms in the sausage and onion mixture can boost nutrition and introduce more vibrant colors and textures to the casserole.
Can I prepare the casserole the night before?
You sure can! Assemble the casserole the night before, cover it tightly, and refrigerate. In the morning, just pop it in the oven and bake as directed for a stress-free breakfast.
What if I don’t have frozen tater tots on hand?
If frozen tater tots aren’t available, you can substitute with hash browns or diced, par-cooked potatoes. The key is to ensure they’re crispy on top, so crisping them in a skillet beforehand can help.
