I'm all for building an entire meal around tater tots. They’re convenient, packed with appealing texture, and quite versatile. This tater tot casserole takes its cues from a diner plate of corned beef hash, but I add some flavor upgrades with onion, bell pepper, Cheddar cheese, and smoked paprika.

For those who crave heat, serve it with slices of pickled jalapeños—the staff in our test kitchen loved how they contrasted with this rich casserole.

“This dish reminds me so much of my childhood, helping my mom open the cans of corned beef,” said recipe tester Melissa Gray. “Such a fun spin on this nostalgic dish. The spice mixture adds dimension to the casserole, perfectly placed on top so it’s the first thing you taste.”

For convenience, the recipe calls for canned corned beef, but if you have leftovers from a meal like corned beef and cabbage, by all means, dice or shred those up and use them instead. Serve this hearty casserole for breakfast, brunch, or dinner. It’s sure to be a family favorite.

  • 8 ounces Cheddar cheese, shredded (about 2 cups)

  • 1 (28-ounce) package frozen potato tater tots

  1. Preheat the oven to 350°F.
  2. Brown the corned beef and vegetables:

    Heat the oil in a large nonstick skillet over medium-high heat. Add the corned beef, onion, and bell pepper. Cook, stirring often and breaking up beef with a wooden spoon, until the corned beef is browned and the vegetables soften, about 10 minutes.

    Spread the corned beef mixture in the bottom of a 9x13-inch baking dish. Sprinkle the cheese evenly over the corned beef. Top with the potato tots in an even layer.

    Whisk the eggs, milk, black pepper, and 1/2 teaspoon of salt in a large bowl until well combined; pour over the potato tots.

    Mix the smoked paprika, chili powder, garlic powder, and remaining 1/2 teaspoon salt in a small bowl until combined. Sprinkle evenly over potato tots.
