Ingredients

  • 1 pound lean ground beef
  • ½ cup yellow onion finely chopped
  • 1 tablespoon minced garlic
  • 2 14.5-ounce cans cut green beans, drained
  • 1 10.5-ounce can cream of mushroom soup, undiluted
  • 1 cup sour cream
  • 1 cup whole milk
  • 1 teaspoon kosher salt
  • 1 teaspoon onion powder
  • ½ teaspoon black pepper freshly cracked
  • 2 cups mild cheddar cheese shredded and divided (½ cup and 1 ½ cups)
  • 32 ounces frozen tater tots

Instructions

  • Preheat the oven to 375°F and spray a 9x13 baking dish with nonstick cooking spray.
  • In a large skillet over medium-high heat, cook the ground beef, onion, and garlic together, stirring occasionally, until the beef is browned and no longer pink. Drain off any excess grease.
  • Spread the beef mixture evenly in the bottom of the prepared baking dish.
  • In a large bowl, whisk together the cream of mushroom soup, sour cream, milk, salt, onion powder, and pepper until smooth.
  • Gently fold in ½ cup of the cheddar cheese and the green beans, taking care not to crush the beans.
  • Spoon the sauce mixture evenly over the beef layer.
  • Sprinkle the remaining 1 ½ cups of cheddar cheese over the top.
  • Arrange the tater tots in a single, even layer over the cheese.
  • Bake for 45 to 50 minutes, until the tater tots are golden brown and the sauce is bubbling around the edges. Serve hot.

Notes

  • Be gentle when stirring the green beans into the sauce so they stay whole instead of breaking apart.
  • You'll know it's done when the tater tots are golden brown and the sauce is bubbling around the edges.
  • To get a head start, assemble everything except the tater tots, cover, and refrigerate for up to a day. Add the tots right before baking so they crisp up properly.
  • Leftovers keep in the fridge for up to 3 days. Reheat in the microwave or in a 350°F oven for about 15 minutes if you want the tots to crisp back up.
