Step-by-Step Instructions
Step 1: Prepare the Beef Mixture
- Preheat your oven to 375°F (190°C).
- Heat olive oil in a large skillet over medium heat.
- Add the chopped onion and sauté for 2–3 minutes until soft.
- Add the ground beef, garlic powder, onion powder, salt, pepper, and Worcestershire sauce.
- Cook until the beef is browned and fully cooked, about 8–10 minutes.
- Drain any excess fat and remove from heat. Stir in chopped pickles.
Step 2: Prepare the Sauce
- In a small bowl, whisk together mayonnaise, ketchup, and mustard.
- Add half of this sauce mixture to the cooked beef and stir to combine. Reserve the rest for drizzling later.
Step 3: Make the Egg Mixture
- In a separate bowl, whisk eggs and heavy cream together until smooth.
- This mixture will hold the casserole together and give it a rich, creamy texture.
Step 4: Assemble the Casserole
- Transfer the beef mixture into a greased 9×13-inch baking dish.
- Pour the egg and cream mixture evenly over the beef.
- Sprinkle shredded cheese over the top.
Step 5: Bake
- Bake uncovered for 25–30 minutes or until the casserole is set and golden brown on top.
Step 6: Garnish and Serve
- Let the casserole cool slightly before serving.
- Drizzle the remaining special sauce over the top.
- Garnish with shredded lettuce, diced tomatoes, sesame seeds, and extra pickles if desired.
Serving Suggestions
- Pair with a side of crispy baked fries or coleslaw for the full burger experience.
- Serve over a bed of lettuce for a Big Mac salad bowl version.
- Add bacon bits or jalapeños for a spicy twist.
- Store leftovers in the fridge for up to 4 days — it reheats beautifully.
