How to Make Big Mac Casserole Step by Step
1. Make the Big Mac Sauce
This is where the magic starts, so don’t skip it! Mix together the mayonnaise, sweet pickle relish, vinegar, garlic powder, onion powder, paprika, turmeric, and sugar in a bowl. Give it a taste and adjust the sweetness if needed. (Pro tip: Let the sauce chill in the fridge while you prep the casserole. It lets all those flavors mingle, making it even tastier.) If you’re feeling adventurous, double the batch—it’s perfect for dipping fries or veggies, too.
2. Cook the Beef
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook until softened—about 3–4 minutes. Toss in the ground beef, garlic powder, Worcestershire sauce, salt, and pepper. Cook until the beef is browned and cooked through, then drain any excess grease. You’ll love the way the Worcestershire sauce gives the beef that savory, umami-packed flavor.
3. Assemble the Casserole
Preheat your oven to 375°F. In a large mixing bowl, combine the cooked beef mixture with the frozen hash browns. Stir everything together until it’s evenly mixed, then layer it into a greased 9×13-inch baking dish. Don’t worry if it looks a little rustic—this is comfort food, not a work of art!
4. Cheese It Up
Sprinkle the shredded cheddar cheese generously over the top. Seriously, don’t skimp—this is where the casserole gets its ooey-gooey goodness. If you’re a cheese lover, feel free to toss in an extra half cup. After all, can you ever have too much cheese?
5. Bake It
Pop the dish into the preheated oven and bake for about 25–30 minutes, or until the cheese is bubbly and golden. (Your kitchen will smell amazing—trust me!) If you like an extra-crispy top, turn on the broiler for the last 2–3 minutes. Just keep an eye on it so it doesn’t burn.
6. Add the Finishing Touches
Once the casserole is out of the oven, let it cool for a couple of minutes. Then, pile on the optional toppings: shredded lettuce, pickles, diced onions, croutons, and sesame seeds. Drizzle with that homemade Big Mac sauce, and you’re good to go. The toppings add a fresh, crunchy texture that pairs perfectly with the warm, cheesy casserole.

Pro Tips for the Best Big Mac Casserole
- Toast Those Croutons: For extra crunch, lightly toast the cubed hamburger buns with a little olive oil and a sprinkle of garlic powder before adding them on top. It’s a small step that makes a big difference.
- Don’t Overmix the Sauce: Stir it gently to keep the relish pieces intact for that signature Big Mac texture. If you like extra sauce, serve some on the side for dipping.
- Add Bacon: Because, let’s face it—bacon makes everything better. Chop it finely and sprinkle it over the top before baking for a salty, crispy kick.
- Layer the Cheese: Mix some cheese into the casserole base before adding the top layer for even more gooey goodness.
FAQs About Big Mac Casserole
Absolutely! You can assemble the casserole up to a day in advance. Just cover it with foil and keep it in the fridge. When you’re ready to bake, let it sit at room temperature for about 15 minutes before popping it in the oven. This makes it a great option for meal prepping or entertaining guests.
Leftovers keep well in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for about 10 minutes, or microwave individual portions for a quick fix. To keep it tasting fresh, store the toppings separately and add them just before serving.
You sure can! Dice fresh potatoes into small cubes and cook them slightly before mixing them into the casserole. This step ensures they’re tender after baking. It’s a bit more work, but the fresh flavor is worth it.
If you’re watching your carbs, swap the hash browns for cauliflower florets. It’s a sneaky way to keep the casserole just as tasty! You can even add extra veggies like zucchini or bell peppers for a twist.
Feel free to get creative! Colby Jack, mozzarella, or a sharp white cheddar would all work beautifully in this dish. For a smoky flavor, try using a smoked gouda or provolone.
