🔪 How to Make Big Mac Casserole
Step 1: Cook the Beef
Heat a skillet over medium heat. Add ground beef and cook until browned, breaking it apart as it cooks. Drain excess fat if needed.
Step 2: Add Flavor
Add onion, garlic, salt, pepper, paprika, and mustard. Cook for 2–3 minutes until fragrant and well combined.
Step 3: Prepare Egg Mixture
In a bowl, whisk eggs and heavy cream until smooth. This helps bind the casserole together.
Step 4: Assemble the Casserole
In a greased baking dish, spread the cooked beef mixture evenly. Sprinkle pickles and shredded cheeses on top. Pour the egg mixture over everything.
Step 5: Bake
Bake at 375°F (190°C) for 25–30 minutes, or until the center is set and the top is golden.
Step 6: Make the Sauce
While baking, mix mayonnaise (or Greek yogurt), ketchup, mustard, pickle juice, garlic powder, and onion powder in a bowl until smooth.
Step 7: Serve
Let the casserole cool slightly, then slice and drizzle with Big Mac sauce. Sprinkle sesame seeds on top for extra burger-style flavor.
