  • 1/2 teaspoon black pepper
  • 1 tsp garlic powder
  • 1/2 tsp ground mustard powder
  • 1/2 tsp onion powder
  • 1 large sweet potatoes peeled and cut into small cubes
  • 2 cups cheddar cheese shredded
  • 1 cup shredded lettuce
  • 1 cup cherry tomatoes halved
  • 1/2 cup diced pickles
  • Splash of Worcestershire sauce

Sauce

  • 1 cup cottage cheese sub plain Greek yogurt or mayo
  • 1 tbsp mayo
  • 3 tbsp ketchup
  • 2 tbsp yellow mustard
  • 1/2 tsp paprika
  • 1-2 tbsp grated sweet onion
  • 1/2 tsp onion powder
  • 1/2 tsp garlic powder
  • 2 tbsp pickles chopped or dill relish
  • 1 tsp white vinegar
  • 2 tsp pickle juice
  • Splash of Worcestershire sauce

Instructions

Casserole

  • Preheat your oven to 375°F (190°C). In a large skillet over medium heat, brown the ground beef, breaking it into crumbles. Drain any excess fat. Add ¾ cup diced onions and minced garlic to the skillet with the cooked beef. Cook until the onions are tender and translucent.
  • Season the beef mixture with a splash of Worcestershire sauce, ground mustard, garlic powder, onion powder, salt, and black pepper.
  • In a separate skillet, sauté the sweet potato cubes until they are just tender.
  • In a greased 9x13 casserole dish, add the cooked sweet potatoes, ground beef mixture, and half the Big Mac sauce. Mix until everything is combined. Sprinkle the shredded cheddar cheese on top.
  • Bake the casserole in the preheated oven for about 20-25 minutes or until the cheese is melted and bubbly. Remove the casserole from the oven and let it cool slightly.
  • Top the casserole with shredded lettuce, halved cherry tomatoes, diced pickles, and 1/4 cup diced onions. Drizzle with more Big Mac Sauce.

Sauce

  • Add all the sauce ingredients except the chopped pickles to a food processor and blend until smooth. Once blended, add in the diced pickles and mix with a spoon until combined.

Notes

Storage + Reheating Tips

  • Fridge: Store leftovers in an airtight container for 4-5 days.
  • Freezer: Yes, you can freeze Big Mac Casserole! Freeze the cooked and cooled casserole in a freezer-safe container or tightly wrapped baking dish for up to 3 months. For best results, thaw overnight in the fridge before reheating.
  • Reheating: Use the microwave for quick lunches or pop it back in the oven for about 10 minutes to re-crisp the cheese.
