Follow these steps to bring the comforting flavors of a Big Mac into your own kitchen:

1. Preheat your oven to 375°F (190°C).
2. In a large skillet over medium heat, add the olive oil and brown the ground beef. Season with salt, black pepper, garlic powder, and onion powder as it cooks, breaking it up with a wooden spoon, about 5-7 minutes.
3. Once the beef is cooked through, drain any excess fat. Stir in the ketchup and mustard, mixing until everything is well combined. Remove from heat.
4. In a small bowl, mix together the mayonnaise and half of the shredded cheddar cheese to create a creamy sauce.
5. In a greased baking dish, spread the cooked beef mixture evenly. Top with diced pickles and onions for that signature Big Mac crunch.
6. Pour the mayo-cheese sauce over the beef layer, spreading it evenly with a spatula.
7. Open the biscuit dough package and cut each biscuit into quarters. Place the biscuit pieces over the casserole, covering the top evenly.
8. Sprinkle the remaining cheddar cheese over the biscuits.
9. Bake in the preheated oven for 20-25 minutes, or until the biscuits are golden brown and the cheese is bubbly.
10. Remove from the oven and let it cool for a few minutes. Just before serving, sprinkle the shredded iceberg lettuce over the top for a fresh, crisp contrast.

As you prepare this dish, don’t rush. Remember how Mama Lou always said that good food is made with patience and love. Savor each step, and you’ll taste the difference.
