Ingredients You’ll Need

2 tablespoons olive oil: For sautéing the onions and adding richness; feel free to swap with another cooking oil like canola.
½ cup chopped yellow onion: Adds sweetness and depth to your beef mixture. You can use white or red onion if preferred.
2 pounds ground chuck: This provides a juicy, beefy base; ground beef is an easy substitute.
1 teaspoon onion powder: Enhances the onion flavor throughout; you could skip this if you prefer to keep it simple.
1 teaspoon garlic powder: A must for depth; fresh minced garlic works great, too—just adjust the amount.
1 teaspoon salt: Essential for bringing out all the flavors; kosher salt is a good choice.
½ teaspoon ground black pepper: A little spice goes a long way! Use white pepper for a less noticeable peppery taste.
1 cup burger sauce: This is what gives the casserole that classic Big Mac taste; consider substituting with a homemade sauce.
¼ cup dill relish: For that signature tang; diced pickles can also work if you prefer a different crunch.
2 cups shredded cheddar cheese: For melty goodness; feel free to use your favorite cheese blend.
32 ounce bag of tater tots: These will top your casserole and create that iconic crispy finish. Hash browns can be a fun alternative if you want a different texture.
½ cup smashburger sauce: This drizzles on top for an extra layer of flavor; you may also use Thousand Island salad dressing.

How to Make Big Mac Casserole

Preheat the Oven: Begin by preheating your oven to 350 degrees Fahrenheit. Prepare your baking dish by spritzing it with nonstick cooking spray to prevent sticking.
Sauté the Onions: In a large skillet over medium heat, add the olive oil and chopped yellow onion. Cook until the onion becomes translucent and fragrant.
Cook the Beef: Add 2 pounds of ground chuck to the skillet. Break the meat into smaller pieces, and sprinkle in the 1 teaspoon onion powder, 1 teaspoon garlic powder, 1 teaspoon salt, and ½ teaspoon black pepper. Continue cooking until the beef is browned and there’s no pink visible.
Drain Excess Fat: Once the beef is thoroughly cooked, drain the majority of the fat from the pan. This keeps your casserole from being greasy.
Combine with Sauce: Pour half of the cup of burger sauce into the skillet along with the ¼ cup of dill relish. Stir to combine everything nicely, ensuring all the flavors meld together.
Incorporate Cheese: Sprinkle in ¼ cup of shredded cheddar cheese, mixing until it melts and becomes gooey throughout the beef mixture.
Transfer to Baking Dish: Pour the hearty ground beef mixture into the prepared casserole dish, spreading it evenly across the bottom.
Add More Cheese: Top the beef layer generously with the remaining cup of shredded cheddar cheese, creating that irresistible cheesy layer.
Layer Tater Tots: Finally, add a single layer of the frozen tater tots on top of the cheese. This will crisp up beautifully while baking.
Bake to Perfection: Place the casserole dish in the preheated oven and bake for 40 to 45 minutes, or until the tater tots are golden brown and the cheese is bubbling.
Cool & Serve: Once out of the oven, let it cool for a few minutes before drizzling with the remaining burger sauce. Top with your favorite burger fixings, and it’s ready to enjoy!

Storing & Reheating

To store any leftovers, let the casserole cool completely and then cover with plastic wrap or transfer to an airtight container. It can sit at room temperature for up to 2 hours before needing refrigeration. If stored properly, your casserole will keep well in the fridge for about 3-4 days. For maximum freshness, you can freeze it for up to 3 months. To reheat, pop it in the oven at 350 degrees until everything is warm and the tater tots are crisp again—about 20-25 minutes. Keep in mind, the texture of your tater tots may soften slightly after freezing, but it’ll still taste fabulous!

Chef’s Helpful Tips

Be careful not to overcook the beef; it should be fully browned, but don’t let it dry out!
For an extra boost of flavor, consider adding some chopped garlic with the onions for a delicious aroma and depth.
Layering the cheese can enhance the creaminess; adding cheese between the layers can be even tastier.
If you want a spicier twist, add jalapeños or crushed red pepper flakes to the beef mixture.
This dish is great for make-ahead meals; prepare it a day in advance and bake it right before your meal.
