How to Make the Recipe

Step 1: Cook the Potatoes

Start by chopping the russet potatoes into small cubes. In a large pot of salted boiling water, cook the potatoes until they are tender, about 10-12 minutes. Drain and set aside.

Step 2: Sauté the Beef and Onions

Heat olive oil in a large skillet over medium heat. Add the chopped onions and cook until they soften, about 4 minutes. Add the ground beef and cook until browned, breaking it up into small crumbles as it cooks. Drain any excess fat if necessary.

Step 3: Add the Seasonings

To the cooked beef and onions, stir in the yellow mustard, garlic powder, onion powder, and water. Cook for another 2-3 minutes, letting the flavors meld together.

Step 4: Combine the Ingredients

In a large mixing bowl, combine the cooked potatoes and the beef mixture. Stir well to ensure everything is evenly distributed.

Step 5: Bake the Casserole

Preheat your oven to 375°F (190°C). Transfer the potato and beef mixture to a greased baking dish. Top with shredded cheddar cheese, spreading it evenly over the casserole. Bake for 20-25 minutes, or until the cheese is melted and bubbly.

Step 6: Serve

Once baked, remove the casserole from the oven and let it sit for 5 minutes before serving. This will help the casserole set and make it easier to cut into portions.

Tips for Making the Recipe

For Extra Flavor: Don’t hesitate to add extra mustard or pickles to the mixture for a more authentic Big Mac flavor.
Make it Crispier: For a crispy topping, sprinkle some breadcrumbs on top of the cheese before baking.
Be Mindful of Salt: The mustard and cheese provide a lot of salt, so be cautious when adding extra salt to the potatoes or beef.
Uniform Potatoes: Cut the potatoes into similar-sized pieces to ensure they cook evenly.
Rest Before Serving: Let the casserole rest for a few minutes after baking to help it set and hold its shape better when serving.

How to Serve

This Big Mac Casserole pairs wonderfully with a simple side salad, roasted vegetables, or even a serving of French fries to keep the theme of the Big Mac. It also works well with a dollop of sour cream or a drizzle of extra mustard for an added punch. For a more decadent experience, serve it with a side of pickle spears.

Make Ahead and Storage

Storing Leftovers

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Simply reheat in the microwave or oven until warmed through.

This casserole can be frozen for up to 3 months. After baking, let it cool completely before wrapping it tightly in plastic wrap or foil. When ready to eat, thaw overnight in the fridge and reheat in the oven.

Reheating
