- 8 slices American cheese (yes, the plastic-wrapped kind)
How to Make Big Mac Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your casserole cooks evenly.
Step 2: Cook the Beef Mixture
- In a cast iron skillet over medium heat, add the ground beef along with the diced onion and minced garlic.
- Cook until the beef is browned and cooked through. Drain any excess fat.
Step 3: Season It Up
- Stir in Worcestershire sauce, yellow mustard, salt, black pepper, garlic powder, and onion powder.
- Mix well until everything is combined.
Step 4: Assemble the Casserole
- In a large bowl, combine the torn hamburger buns with melted butter and sesame seeds until well coated.
- Layer half of the bun mixture in a baking dish.
- Spread half of the beef mixture over the buns.
Step 5: Add Cheese & Sauce Layers
- Sprinkle with shredded cheddar cheese.
- In another bowl, mix mayonnaise, ketchup, sweet pickle relish, yellow mustard, white vinegar, sugar, paprika, garlic powder, and onion powder. Spread half of this sauce mixture over the cheese layer.
Step 6: Repeat Layers
Repeat layers with remaining bun mixture followed by remaining beef mixture. Top with remaining sauce mixture and American cheese slices.
Step 7: Bake to Perfection
Bake in preheated oven for about 30 minutes, or until bubbly and golden on top. Let it cool slightly before serving with shredded lettuce and chopped dill pickles on top. Enjoy your delicious Big Mac Casserole!

How to Perfect Big Mac Casserole

- Use Stale Buns – Stale hamburger buns soak up flavors better, creating a more cohesive casserole.
- Season Generously – Don’t skimp on spices; they are crucial for replicating that classic burger taste.
- Bake Until Golden – Ensure the top is bubbly and golden brown for a delicious contrast in texture.
- Let it Rest – Allow your casserole to sit for about 10 minutes after baking; this helps it set and makes serving easier.
- Experiment with Cheeses – Feel free to mix in different cheeses like Monterey Jack or pepper jack for added flavor depth.
Best Side Dishes for Big Mac Casserole
Pairing side dishes with your Big Mac Casserole can elevate your meal experience. Here are some great options:
- French Fries – Crispy fries are a classic pairing; bake or fry them until golden and serve alongside your casserole.
- Sweet Potato Wedges – Roasted sweet potatoes add a hint of sweetness and complement the savory flavors beautifully.

Common Mistakes to Avoid
To ensure your Big Mac Casserole turns out perfect, here are a few common mistakes to avoid.
- Skipping the seasoning: Many people forget to season the ground beef properly. Make sure to use Worcestershire sauce, mustard, and spices for that authentic flavor.
- Using fresh hamburger buns: Fresh buns can become mushy in the casserole. Opt for stale buns or toast them slightly to maintain the right texture.
- Not mixing the sauces thoroughly: If the mayo, ketchup, and relish aren’t well combined, some bites might taste bland. Mix them well for consistent flavor throughout.
- Overcooking the casserole: Keep an eye on your casserole while it’s baking. Overcooking can lead to dry ingredients. Aim for a bubbly top without burning it.
- Ignoring the cheese layer: The cheese is essential for that gooey, melty experience. Don’t skip or skimp on it; use a generous amount of cheddar and American cheese.
