Ingredients

Scale
  • 1 1/2 lbs ground beef (85/15 recommended)
  • 1/2 cup yellow onion, diced
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1/2 tsp smoked paprika
  • 1/2 cup mayonnaise
  • 2 tbsp ketchup
  • 2 tbsp sweet pickle relish
  • 1 tbsp yellow mustard
  • 1 tbsp white vinegar
  • 1/2 tsp onion powder
  • 1/2 tsp garlic powder
  • 1/2 tsp paprika
  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup dill pickle chips, chopped
  • 1/4 cup sesame seeds (optional)
  • 4 cups shredded iceberg lettuce
  • 1/2 cup diced tomatoes (optional topping)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with oil or nonstick spray.
  2. In a large skillet over medium-high heat, cook ground beef for 6-8 minutes, breaking it up as it cooks. Add diced onion, salt, black pepper, garlic powder, and smoked paprika. Continue to cook until beef is browned and onions are soft, about 4 minutes more. Drain excess fat if needed.
  3. In a medium bowl, whisk together mayonnaise, ketchup, sweet pickle relish, yellow mustard, white vinegar, onion powder, garlic powder, and paprika to make the special sauce. Taste and adjust seasoning as desired.
  4. Spread the cooked beef and onion mixture evenly in the prepared baking dish. Drizzle half of the special sauce over the beef (reserve the rest for serving).
  5. Sprinkle shredded cheddar and mozzarella cheese evenly over the beef. Top with chopped dill pickles.
  6. Sprinkle sesame seeds on top if using. Bake uncovered for 20-25 minutes, until cheese is melted and bubbling.
  7. Let the casserole rest for 5-10 minutes after baking.
  8. Top with shredded iceberg lettuce and diced tomatoes. Drizzle remaining special sauce over the top.
  9. Scoop out portions and serve hot.

Notes

For best results, use freshly shredded cheese for optimal melt. Add pickles before baking for signature flavor. Adapt with ground turkey or plant-based meat for dietary needs. Add extra veggies to the beef layer for more nutrition. Top with lettuce and tomato only after baking for crunch. Casserole can be made ahead (without lettuce/tomato) and refrigerated up to 24 hours before baking.
