Smoked Paprika (1 ½ teaspoons): Offers a mild smoky depth that rounds out the spices.
Kosher Salt (1 teaspoon): Essential seasoning to enhance all flavors evenly.
Black Pepper (1 teaspoon): Adds subtle heat and complexity.

Instructions

Preheat and Prepare Baking Dish: Set your oven to 425°F and lightly grease a 9×13 baking dish. This ensures a non-stick surface and even baking.
Brown Ground Beef and Onions: In a large skillet over medium-high heat, cook the ground beef with finely chopped onions until beef is no longer pink, about 6 to 8 minutes. Drain excess fat to avoid greasiness and ensure a clean flavor.
Mix in Signature Sauce and Seasonings: Add 1 cup of Thousand Island dressing, chopped dill pickles, mayonnaise, ketchup, mustard, onion powder, smoked paprika, kosher salt, and black pepper to the beef mixture. Stir thoroughly to combine, infusing the beef with all the classic Big Mac flavors.
Layer Meat Mixture in Casserole Dish: Spread the savory beef filling evenly in the prepared baking dish, creating a thick base layer for the casserole.
Add Cheese Layer: Sprinkle the shredded mild cheddar cheese evenly over the beef mixture. This layer melts during baking, adding creaminess and richness.
Arrange Frozen Tater Tots on Top: Place the frozen tater tots in a single layer over the cheese. Avoid overcrowding to allow the tots to crisp up evenly during baking.
Bake Until Golden and Crispy: Bake uncovered for 25 to 30 minutes until the tater tots turn golden brown and crispy, signaling the casserole is perfectly cooked through.
Rest and Add Fresh Toppings: Let the casserole cool for a few minutes to set, then evenly spread shredded lettuce on top. This fresh layer adds crunch and a refreshing contrast.
Finish with Dressing and Garnish: Drizzle the remaining ¼ cup of Thousand Island dressing over the lettuce and sprinkle sesame seeds if using. Serve hot for a comforting, crowd-pleasing meal.

You Must Know

For crispier tater tots, pre-bake them before layering to avoid sogginess.
