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
Expert Tips
-
- Potatoes: If you opt for crispy tater tots, diced potatoes, or hash browns, make sure to cook them first before adding to the casserole. For frozen potatoes, cook according to package instructions until golden brown and cooked through (I recommend the air fryer!). For raw, diced potatoes, cook them the same way as the sweet potatoes in the recipe, but adjust the cooking times if needed.
-
- Keto Big Mac Casserole: If you’re keto, omit the potatoes and make everything else the same! It will still be a delicious casserole with all the classic Big Mac flavors.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 4-5 days. Reheat in the microwave or oven, and enjoy! If you have leftover sauce, store it in a separate airtight container for up to a week in the fridge. Use it as a salad dressing, dip, or on sandwiches. If desired, you can store it in a freezer-safe container in the freezer for up to 2-3 months.Nutrition
