Ingredients You’ll Need

For the Casserole Base:

- Worcestershire Sauce: 1 tablespoon for a deeper, savory flavor.
- Salt & Pepper: To taste.

How to Make Big Mac Casserole Step-by-Step
Follow these simple instructions for a perfect casserole every time.
- Preheat and Prepare: Preheat your oven to 400°F (200°C). Grease a 9×13 inch baking dish.
- Make the Special Sauce: In a small bowl, whisk together all the sauce ingredients: mayonnaise, French dressing, relish, minced onion, vinegar, and sugar. Cover and refrigerate while you prepare the casserole.
- Cook the Beef and Onions: In a large skillet over medium-high heat, cook the ground beef and chopped onion until the beef is browned and the onion is soft. Drain any excess grease. Stir in the Worcestershire sauce, salt, and pepper.
- Assemble the Base: Spread the cooked beef mixture evenly into the bottom of the prepared baking dish. Arrange the potato cubes or tater tots over the beef.
- Add the Cheese: Sprinkle 2 cups of the shredded cheddar cheese evenly over the potato layer.
- Bake to Perfection: Bake for 20-25 minutes, or until the potatoes are cooked through and the cheese is bubbly and melted.
- Add Toppings and Serve: Remove the casserole from the oven. Let it cool for 5 minutes. Drizzle generously with the prepared Big Mac sauce. Top with shredded lettuce, chopped pickles, the remaining 1 cup of cheese, and a sprinkle of sesame seeds. Serve immediately.
Tips for the Best Cheeseburger Casserole
- Use Lean Beef: To prevent a greasy casserole, opt for 85/15 or 90/10 lean ground beef. Always drain the fat after browning.
- Shred Your Own Cheese: Pre-shredded cheese is coated with anti-caking agents that can prevent it from melting smoothly. For the best gooey, melty results, buy a block and shred it yourself.
- Let It Rest: Allowing the casserole to rest for 5-10 minutes after baking helps it set, making it easier to slice and serve.
Popular Variations and Substitutions
One of the best things about this Big Mac Casserole is how easy it is to customize.
Big Mac Tater Tot Casserole
For an even easier and crispier topping, substitute the potato cubes with a layer of frozen tater tots. This version is a guaranteed crowd-pleaser and is very similar to another favorite, the cheeseburger tater tot casserole.
Keto Big Mac Casserole
To make this low-carb, simply omit the potato layer. You can add a layer of cauliflower rice or simply bake the beef and cheese mixture on its own. Ensure your special sauce is made with a sugar-free French dressing and a sugar substitute.
Other Ideas
- Ground Meat: Swap the ground beef for ground turkey or chicken for a lighter version.
- Add Bacon: Because everything is better with bacon! Add cooked, crumbled bacon to the beef mixture or sprinkle it on top.
- Spice It Up: Add a dash of hot sauce to the beef mixture or some sliced jalapeños on top for a spicy kick.
What to Serve with Your Casserole
This casserole is a complete meal on its own, but it also pairs wonderfully with classic burger sides. Consider serving it with a side of air fryer french fries, a simple green salad, or steamed green beans. It’s also fantastic with our Ground Beef and Rice Casserole for a dinner party with options.
