Variations

Spicy Mac Casserole

Add jalapeños to the beef mixture and a dash of hot sauce to the Big Mac sauce for a kick.

Loaded Potato Version

Double the potatoes, add bacon bits, and use sour cream in addition to the Big Mac sauce for a loaded baked potato twist.

Keto-Friendly

Replace the potatoes with cauliflower florets and use a keto-friendly ketchup in the sauce.

How to Make Big Mac Casserole

Step 1: Prepare the Potatoes

Preheat your oven to 375°F. Chop your potatoes into small bite-sized pieces – smaller chunks cook faster and better absorb flavors. Heat olive oil in a pan, add potatoes with water, season generously with salt and pepper, and cook until they begin to soften, about 5-10 minutes. Transfer to your baking dish.

Step 2: Cook the Beef Mixture

In the same pan (no need to clean it), cook ground beef and onions until the meat is mostly browned and onions have softened. Season with salt, pepper, garlic powder, onion powder, and yellow mustard. Stir well to incorporate all those flavors, then combine with the potatoes in your baking dish.

Step 3: Bake with Cheese

Sprinkle the cheddar cheese evenly over the beef and potato mixture. Cover with foil and bake for 15 minutes until the cheese is completely melted and everything is heated through.

Step 4: Prepare the Big Mac Sauce

While the casserole bakes, mix mayonnaise, ketchup, chopped pickles, and pickle juice in a bowl. Refrigerate until ready to use.

Step 5: Add the Toppings

Remove the casserole from the oven, discard the foil, and drizzle all of the Big Mac sauce over the top. Scatter shredded lettuce, chopped onion, tomato pieces, and pickle chips across the surface.

Pro Tips for Making the Recipe

• Potato Size Matters: Cut potatoes into very small pieces for faster cooking and better texture in the final dish.
• One-Pan Efficiency: Using the same pan for potatoes and beef builds layers of flavor and minimizes cleanup.
• Sauce Application: The Big Mac sauce is best when generously applied while the casserole is still hot, allowing it to slightly melt into the top layer.
• Don’t Skip the Pickle Juice: This ingredient is crucial for authentic Big Mac flavor in the sauce.
• Fresh Toppings Last: Add lettuce and fresh toppings right before serving to maintain their crispness.

How to Serve

Main Meal

Serve this casserole as a complete meal – it already contains protein, vegetables, and starch.

Side Dishes

• A crisp garden salad with vinaigrette

Presentation

For maximum visual impact, serve directly from the baking dish with all toppings visible, or plate individual portions making sure each serving gets a good distribution of sauce and toppings.

Make Ahead and Storage

Storing Leftovers

Store the base casserole (beef, potatoes, and cheese) separately from the sauce and fresh toppings in airtight containers in the refrigerator for up to 3 days. The sauce will keep well refrigerated for about 5 days.

Freezing

The base casserole can be frozen without the toppings for up to 3 months. Wrap tightly in foil and place in a freezer-safe container. The sauce can be frozen separately in small portions.

Reheating

Thaw frozen casserole overnight in the refrigerator. Reheat the base casserole in a 350°F oven until heated through (about 20-25 minutes), or portion and microwave until hot. Add fresh toppings after reheating.

FAQs

Can I prep this casserole ahead of time?
Absolutely! You can prepare the beef and potato base up to the point of baking, cover and refrigerate for up to 24 hours. When ready to serve, add an extra 10 minutes to the baking time since it’ll be cold. Make the sauce ahead too, but save the fresh toppings for just before serving.

What can I substitute for ground beef?
Ground turkey, chicken, or plant-based meat alternatives work well. Each will give a slightly different flavor profile, but with the distinctive Big Mac sauce, you’ll still get that familiar taste experience. Just be sure to add a bit more olive oil when cooking leaner meats.

Is there a way to make this recipe lower in carbs?
Yes! Replace the potatoes with cauliflower florets or diced turnips. They’ll provide a similar texture without the carb content. You can also look for reduced-sugar ketchup for the sauce to further lower the carb count.

Can I double this recipe for a larger crowd?
Definitely. Simply double all ingredients and use a larger baking dish. The baking time may need to increase by 5-10 minutes, so check that everything is heated through before adding your toppings.
