Ingredient Notes

Big Mac Casserole

Full recipe with measurements located in the recipe card.

• lean ground beef: Feel free to substitute ground turkey if desired. A bit healthier than beef, but you really can’t tell any difference in taste in the casserole.
• yellow onion or white onion
• minced garlic
• spices: Salt, black pepper, garlic powder, ground mustard powder, and onion powder.
• sweet potatoes: I used peeled and cubed sweet potatoes for a bit of a healthier spin for my family, but you can use Yukon gold potatoes, Russet potatoes, or even frozen tater tots/hash browns if desired.
• cheddar cheese
• shredded lettuce
• cherry tomatoes
• dill pickles
• splash of Worcestershire sauce: I recommend checking labels for a gluten-free version if you are gluten intolerant. Otherwise, the recipe is completely gluten-free.

• mayonnaise

Step-by-Step Instructions

Big Mac Casserole

1. 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 grease. Add ¾ cup diced onions and minced garlic to the skillet with the cooked beef. Cook until the onions are tender and translucent.
2. Season the beef mixture with a splash of Worcestershire sauce, ground mustard, garlic powder, onion powder, salt, and black pepper.
3. In a separate skillet, sauté the sweet potato cubes until they are just tender.
4. In a greased 9×13 baking dish, add the cooked sweet potatoes, ground beef mixture, and half the Big Mac sauce. Mix until everything is combined. Sprinkle the shredded cheese on top of the casserole.
5. 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.
6. Top the casserole with the fresh lettuce, halved cherry tomatoes, diced pickles, and diced onions. Drizzle with more Big Mac Sauce.
