This tater tot breakfast casserole brings together crispy potatoes, savory ham, and melty cheese for the ultimate family-friendly morning dish. I created this recipe after hosting weekend guests who raved about it so much they requested the recipe before leaving.
I first made this casserole when my in-laws visited unexpectedly. With limited time and ingredients, this dish saved breakfast and has now become our standard weekend tradition when family comes to town.
Ingredients
- Frozen tater tots: The star of the dish providing that perfect crispy texture on top while staying tender inside
- Diced ham: Adds hearty protein and savory flavor; use leftover holiday ham for even more flavor
- Cheddar cheese: Offers that classic sharp flavor that pairs perfectly with eggs and potatoes
- Mozzarella or Monterrey Jack cheese: Creates the stretchy melty texture everyone loves
- Eggs: Provide structure and richness to bind everything together
- Milk: Helps create a custard-like texture with the eggs
- Sour cream: Adds tanginess and creaminess that balances the dish
- Seasonings: Garlic powder, onion powder, salt, and pepper enhance flavor without overpowering
- Hot sauce: Optional but adds a subtle kick without making it spicy
How To Make Tater Tot Breakfast Casserole
- Prep the Baking Dish:
- Preheat your oven to 375°F and thoroughly coat a 9x13 inch baking dish with nonstick spray making sure to get the corners and sides to prevent sticking.
- Combine Dry Ingredients:
- Add the frozen tater tots straight from the freezer (no need to thaw), diced ham, and most of both cheeses to the baking dish. Gently toss everything with your hands to ensure even distribution throughout the casserole.
- Create Egg Mixture:
- In a large bowl whisk together eggs, milk, and sour cream until smooth with no streaks. Add salt, pepper, garlic powder, onion powder, and hot sauce if using. Whisk again until completely incorporated; this creates the flavorful custard base.
- Assemble the Casserole:
- Pour the egg mixture evenly over the tater tot mixture taking care to coat all ingredients. The liquid should seep down between the tater tots and ham pieces.
- Bake to Perfection:
- Bake uncovered for a full 45 minutes until the top is beautifully golden brown and the center is set. Add the reserved cheese on top and return to the oven for 5 more minutes until melted and bubbly.

The sour cream is my secret weapon in this recipe. I discovered its importance accidentally when I ran out of heavy cream one morning. The tanginess it adds creates depth that guests always notice but can never quite identify. When my daughter was little, she called this "potato puzzle breakfast" because of how all the ingredients fit together like a delicious puzzle.
Make Ahead Instructions
This casserole works beautifully as a make-ahead breakfast. Simply assemble everything up to the point of baking, cover tightly with plastic wrap, and refrigerate overnight. In the morning, remove from the refrigerator while the oven preheats, then bake as directed, adding about 5-10 minutes to the cooking time since you're starting with a cold casserole. This has saved countless holiday mornings when I'd rather be opening presents than cooking breakfast.

Easy Variations
The beauty of this breakfast casserole lies in its versatility. Try swapping the ham for crumbled breakfast sausage or bacon for a different flavor profile. Vegetarians can skip the meat entirely and add sautéed mushrooms, bell peppers, and spinach instead. The cheese can also be customized; use pepper jack for a spicy kick or a Mexican blend for a southwestern twist. My family loves it when I add a layer of diced avocado and fresh cilantro right before serving for a California-inspired version.
Serving Suggestions
While this casserole is hearty enough to be a complete meal on its own, I like to serve it with fresh fruit to balance the richness. A simple green salad dressed with lemon vinaigrette makes a lovely accompaniment for brunch gatherings. For special occasions, offer toppings like salsa, extra sour cream, sliced green onions, or hot sauce so guests can customize their portions. This dish pairs wonderfully with mimosas or a spicy Bloody Mary for weekend brunches.
