Step-by-Step Guide to Making Big Mac Casserole
Follow these steps carefully for restaurant-quality results.
Step 1 – Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
Step 2 – Cook the Ground Beef
In a large skillet over medium heat, cook ground beef until browned and fully cooked. Break it apart as it cooks. Drain excess grease, then season with salt, pepper, garlic powder, and onion powder.
Step 3 – Add Flavor
Stir in a small amount of mustard and chopped onions to mimic classic burger flavor. Mix well and remove from heat.
Step 4 – Prepare the Sauce
In a bowl, combine mayonnaise, ketchup, mustard, a splash of vinegar, and finely chopped pickles. Stir until smooth to create a “special sauce.”
Step 5 – Layer the Casserole
Spread the cooked beef evenly in the prepared baking dish. Sprinkle shredded cheddar cheese generously over the top.
Step 6 – Bake
Place the dish in the oven and bake for 15–20 minutes, or until the cheese is melted and bubbly.
Step 7 – Add Fresh Toppings
Remove from the oven and let it cool slightly. Top with shredded lettuce, diced tomatoes, extra pickles, and a drizzle of the prepared sauce.
Step 8 – Serve and Enjoy
Slice and serve warm. For a low-carb option, enjoy as is. For a traditional feel, serve over toasted sesame buns or alongside fries.
