Ingredients You’ll Need

Here’s everything you’ll need to bring this Big Mac-inspired casserole to life:

2 pounds lean ground beef – A classic choice for that Big Mac flavor, but you can also substitute ground turkey or chicken.
1 cup yellow onion, diced – Adds sweetness and depth to the beef mixture.
1¼ cups Thousand Island dressing – The “secret sauce” flavor that makes it taste like a Big Mac.
¾ cup dill pickles, chopped – The tangy crunch that Big Mac lovers crave.
3 tablespoons mayonnaise – For creaminess.
2 tablespoons ketchup – Adds sweetness and balances the flavors.
2 teaspoons mustard – Brings in that sharp, zesty bite.
2 teaspoons onion powder – To deepen the onion flavor.
1½ teaspoons smoked paprika – A smoky touch that makes this casserole special.
1 teaspoon kosher salt – To season the beef mixture.
1 teaspoon black pepper – Adds mild heat and balance.
2 cups mild cheddar cheese, shredded – Because everything is better with melted cheese.
1 package frozen tater tots – The star of the casserole, giving it that irresistible crunch.
1½ cups shredded lettuce – Added at the end for freshness, just like in a Big Mac.
2 teaspoons sesame seeds – A fun garnish that makes the casserole look like a burger bun.

Step-by-Step Instructions

Step 1 – Cook the Beef and Onion

Preheat your oven to 375°F (190°C).
In a large skillet over medium heat, cook the ground beef and diced onion together until the beef is browned and the onion is soft. Drain any excess grease so your casserole doesn’t get oily.

Step 2 – Season the Mixture

To the beef and onion mixture, stir in the mayonnaise, ketchup, mustard, onion powder, smoked paprika, salt, and black pepper. Mix everything until the beef is evenly coated and flavorful. This step gives the meat that signature Big Mac taste.

Step 3 – Assemble the Casserole

Grease a 9×13-inch baking dish. Spread the beef mixture evenly across the bottom.
Drizzle Thousand Island dressing over the beef and sprinkle the chopped pickles on top.
Add 1 cup of shredded cheddar cheese to create a melty, cheesy layer.
Finally, arrange the frozen tater tots in a single layer across the entire surface.

Step 4 – Bake

Bake the casserole uncovered for 35–40 minutes, or until the tater tots are golden brown and crispy.
Sprinkle the remaining cup of cheddar cheese on top and bake for another 5 minutes, just until the cheese melts beautifully.

Step 5 – Garnish and Serve

Once baked, let the casserole cool for about 5 minutes.
Top it with shredded lettuce and sesame seeds before serving. This makes it look and taste just like a Big Mac in casserole form.
