Ingredients

  • 2 pounds ground beef
  • 1 onion (diced)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • 1/2 teaspoon ground black pepper
  • 1 tablespoon Worcestershire sauce (gluten-free)
  • 3/4 cup Thousand Island dressing (180g, gluten-free if needed)
  • 1/2 diced pickles (100g)
  • 2 cup shredded cheddar cheese (8 oz/227g, divided)
  • 24 oz tater tots (gluten-free if needed )

For topping:

  • 2 tablespoons gluten-free Thousand Island dressing
  • 1/2 cup diced tomatoes
  • 1/4 cup sliced pickles
  • 1/2 cup shredded lettuce
  • 1 tablespoon sesame seeds

Instructions

  • Preheat your oven to 400°F (205°C).
  • Place a skillet or cast iron pan on the stove top over medium heat. Add the ground beef and onion and cook for 6-8 minutes, breaking up the beef with a spatula as it cooks.
  • Cook until no more pink remains and the onions are translucent. If there is a lot of fat in the skillet, drain most of it with a spoon.
  • Add the garlic powder, onion powder, salt, pepper, worcestershire sauce, dijon mustard, Thousand Island dressing and diced pickles to the ground beef mixture. Stir to combine.
  • Cook for an additional 2-3 minutes.
  • Sprinkle 1 1/2 cups of the shredded cheddar cheese evenly over the dressing layer.
  • Arrange the gluten-free tater tots on top of the cheese layer in a single layer. Sprinkle with the remaining 1/2 cup of shredded cheese.
  • Bake the casserole in the preheated oven for 35-40 minutes, or until the tater tots are golden brown and crispy, and the cheese is melted and bubbly.
  • Once cooked, remove the casserole from the oven and let it cool for a few minutes. Sprinkle sliced pickles, shredded lettuce, diced tomatoes, and sesame seeds on top, if desired.
  • Serve and enjoy!

Notes

  • If you have celiac disease like me or are on a gluten-free diet for any reason, be sure to double check your ingredients to ensure they are gluten-free. The worcestershire sauce, Thousand Island dressing and tater tots are 3 ingredients you will need to make sure are gluten-free when shopping at your local grocery store. 
  • Opt for lean ground beef to minimize fat content. If you're using a higher-fat cut, make sure to drain the excess fat after cooking.
  • Pre-shredded cheddar saves time, but for better melt and flavor, shred your own block of cheddar.
  • Oven temps can vary; start checking at the 30-minute mark to avoid overcooking.
