Step-by-Step Instructions
Cook the Pasta and Beef
Preheat the oven to 375°F and lightly grease a casserole dish. Bring a large pot of salted water to a boil and cook the pasta shells until al dente. Drain and set aside while preparing the filling.
In a large skillet over medium-high heat, cook the ground beef until browned and fully cooked. Add diced onion and sauté until softened. Stir in garlic and cook briefly until fragrant. Drain excess grease to keep the casserole rich but not overly oily.
Prepare the Big Mac Sauce
In a medium bowl, whisk together mayonnaise, ketchup, mustard, pickle relish, garlic powder, onion powder, smoked paprika, salt, and black pepper until smooth and creamy.
This sauce creates the signature burger-inspired flavor that makes the casserole taste similar to a loaded cheeseburger. The combination of creamy, tangy, and savory ingredients delivers balance while coating the pasta and beef evenly throughout the dish.
Assemble the Casserole
In a large mixing bowl, combine cooked pasta, seasoned beef mixture, diced pickles, heavy cream, and prepared sauce. Stir thoroughly until every ingredient is evenly coated and creamy.
Transfer the mixture into the casserole dish and spread evenly. Top with cheddar cheese and mozzarella cheese, ensuring full coverage for a rich golden topping. Sprinkle sesame seeds lightly over the top to mimic classic burger bun flavor and presentation.
Bake Until Hot and Bubbly
Bake uncovered for 25–30 minutes until the cheese melts completely and becomes golden around the edges. The casserole should feel hot throughout while maintaining a creamy center texture.
Allow the casserole to rest for 5–10 minutes before serving. This helps the sauce thicken slightly and improves serving consistency. Garnish with extra pickles, lettuce, or tomatoes if desired for a full burger-inspired experience.

Servings
This Big Mac Casserole Recipe makes approximately 6 generous servings, making it ideal for family dinners, meal prep, and casual gatherings. The hearty beef, cheese, and pasta combination creates a filling and satisfying comfort food meal.
When paired with salad, roasted vegetables, or garlic bread, the casserole can comfortably serve up to 8 people, making it practical for potlucks and entertaining guests.
The leftovers also reheat exceptionally well, and many people find the burger-inspired flavors even richer the following day after the ingredients continue blending together.
Common Mistakes in This Recipe
Using overly greasy ground beef can make the casserole heavy and oily instead of creamy and balanced.
Overcooking the pasta before baking often results in soft or mushy texture after the casserole finishes cooking in the oven.
Adding too many pickles or too much relish may overpower the cheese and beef flavors throughout the dish.
Skipping the resting period after baking can cause the casserole to feel loose and difficult to serve cleanly.
Solutions to Common Mistakes
Drain excess grease thoroughly after browning the beef to maintain a creamy but balanced casserole texture.
Cook pasta only until al dente so it remains firm and structured after baking with the sauce and cheese.
Measure pickles and relish carefully to preserve the signature burger flavor without overwhelming the casserole.
Allow the casserole to rest several minutes before serving so the sauce thickens slightly and the portions hold together properly.
