  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 small onion finely diced
  • 2 tablespoon yellow mustard
  • 1 tablespoon Worcestershire sauce
  • 1 32 oz frozen tater tots
  • 2 cups shredded cheddar cheese
  • 1 cup torn American cheese
  • ½ cup diced dill pickles

Instructions

  • In a large skillet over medium heat, cook the ground beef until browned, breaking it apart as it cooks.
  • Season the beef with the salt, pepper, garlic powder, and onion powder.
  • Add the diced onion and cook for 3–4 minutes until softened.
  • Stir in the mustard and Worcestershire sauce.
  • Drain any excess grease.
  • Lightly spray a 6-quart slow cooker with nonstick cooking spray.
  • Spread half of the seasoned beef mixture into the bottom of the slow cooker.
  • Sprinkle with half of the cheddar cheese and half of the American cheese.
  • Arrange half of the tater tots over the cheese.
  • Repeat the layers with the remaining beef, cheeses, and tater tots.
  • Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours.
  • During the last 20 minutes of cooking, sprinkle the diced pickles over the casserole and recover.
  • While the casserole finishes cooking, whisk together all of the Big Mac sauce ingredients until smooth.
  • Let the casserole rest for 5 minutes.
  • Drizzle generously with Big Mac sauce.
  • Sprinkle with sesame seeds.
  • Top individual servings with shredded lettuce, extra pickles, and additional sauce if desired.

Notes

Add the lettuce after serving so it stays crisp. 
American cheese helps create the authentic Big Mac flavor. 
For the best texture, use frozen tater tots straight from the freezer. 
The sesame seeds really help sell the "Big Mac" look.
