Ingredients You’ll Need

32 ounces frozen tater tots: A must-have for that golden-brown crunch that creates the base of this dish.
16 ounces ham, ¼” dice: Use diced ham for savory bursts of flavor throughout the casserole; leftover ham works great as a substitute!
2 cups shredded sharp cheddar cheese: This cheese provides a tangy taste; feel free to mix in other types like Monterey Jack for a twist.
¼ cup sliced green onions: For a pop of color and refreshing flavor; scallions can be swapped in if you prefer.
¼ cup cornstarch (optional): This can help thicken the egg mixture slightly, but it’s optional based on your texture preference.
1 teaspoon kosher salt: Essential for bringing out all the flavors in the casserole.
½ teaspoon garlic powder: This adds a subtle kick; fresh minced garlic can also work wonderfully.
½ teaspoon onion powder: Enhances the onion flavor without overwhelming the dish.
¼ teaspoon smoked paprika (optional): Adds a hint of smokiness; you can skip it if you prefer a milder taste.
¼ teaspoon black pepper: A little heat to balance the richness of the dish.
8 large eggs: They bind everything together, creating that custardy goodness.
2 ½ cups half-and-half: This rich dairy product makes for a creamy texture; whole milk can work in a pinch but won’t be quite as indulgent.

How to Make Tater Tot Breakfast Casserole

Preheat the Oven: Set the oven rack to the center position and preheat it to 350ºF (177ºC). Grease a 9×13-inch baking dish with a little oil or cooking spray to ensure an easy release after baking.
Mix the Ingredients: Evenly spread the frozen tater tots at the bottom of the greased baking dish. Then, sprinkle the diced ham, 1 cup of shredded cheddar cheese, and sliced green onions over the top—each layer adds a burst of flavor!
Add the Egg Base: In a large bowl, whisk together the cornstarch (if using), salt, garlic powder, onion powder, smoked paprika (if using), and black pepper. Once evenly combined, add the eggs and whisk until frothy. Gradually whisk in the half-and-half until everything is blended and creamy. Pour this mixture over the tater tots and other ingredients in the baking dish, making sure it distributes evenly. Finally, sprinkle the remaining 1 cup of shredded cheese on top for an extra cheesy finish!
Bake the Casserole: Transfer the baking dish to the oven and bake for 45 to 55 minutes. You’ll know it’s done when the center is set and a toothpick inserted comes out clean, with an internal temperature of 180 to 190ºF (82 to 88ºC). Once baked, let it cool for about 10 minutes before slicing and serving.

Storing & Reheating

To store leftover casserole, let it cool to room temperature, then cover it tightly with plastic wrap or transfer it to an airtight container. It can be kept in the refrigerator for up to 4 days. For longer storage, consider freezing it; wrap individual portions in foil and place them in a heavy-duty freezer bag where it can last up to 3 months. When ready to enjoy, reheat slices in the microwave for about 1-2 minutes, or place your casserole back in a 350ºF oven until warmed through. Be aware that the texture might change slightly, but a sprinkle of fresh cheese before reheating can help refresh its goodness.

Chef’s Helpful Tips

Always grease your baking dish well to avoid sticking, ensuring easy serving.
For even cooking, try using room temperature eggs; they blend more seamlessly with the other ingredients.
If you prefer extra crispy tater tots, consider toasting them in the oven for a few minutes before adding them to the dish.
Allow yourself the freedom to get creative! Add vegetables such as bell peppers or mushrooms for extra nutrition.
Make this casserole a day ahead to let the flavors meld—just refrigerate before baking and add an additional 5-10 minutes to your cooking time.

Tater Tot Breakfast Casserole combines comfort and flavor with ease, making it an excellent choice for gatherings or family breakfasts. You’ll likely find that every forkful elicits joyful responses around your table. Feel free to experiment and make the recipe your own, adjusting flavors and ingredients to fit your family’s tastes. Enjoy every cheesy bite and make plenty of memories while savoring this wonderful dish!

Recipe FAQs

Can I make this casserole ahead of time?

Absolutely! You can prepare Tater Tot Breakfast Casserole the night before. Just assemble it in the baking dish, cover it well, and place it in the refrigerator. In the morning, just pop it in the oven, adding a few minutes to the baking time since it will be cold.

Can I use fresh potatoes instead of frozen tater tots?

Though tater tots are suggested for their crunchy texture and ease, you can use fresh diced potatoes. Par-cook them beforehand by boiling or roasting until just tender for a similar effect. Keep in mind that the bake time may vary.

What can I substitute for half-and-half?

You can substitute whole milk or a mix of heavy cream and milk to achieve a similar creaminess. If you want a lighter option, consider using a non-dairy milk like almond or oat milk, but this could alter the flavor and richness.

How do I know when the casserole is done?

The casserole is fully baked when the edges are golden brown, the center is set, and a toothpick inserted comes out clean. For safety, ensure the internal temperature reaches between 180ºF (82ºC) and 190ºF (88ºC).
