Ingredients
- 2 lbs lean ground beef
- 1 cup yellow onion, diced
- 1 ¼ cups Thousand Island dressing
- ¾ cup dill pickles, chopped
- 3 tbsp mayonnaise
- 2 tbsp ketchup
- 2 tsp mustard
- 2 tsp onion powder

After making this casserole more times than I can count, I’ve learned which ingredients matter most. Lean ground beef really is ideal—you don’t want a greasy casserole—though you can swap in ground turkey if you prefer something lighter. Don’t skip the dill pickles; they add the tang that gives this dish its unmistakable Big Mac personality. And if you only have regular paprika, it will still work, but smoked paprika adds such a deeper, richer warmth. As for Thousand Island dressing, I’ve tested several brands and they all work fine, but the thicker ones tend to hold up best in the casserole.
Equipment Needed
- Large skillet
- 9×13 baking dish
- Mixing bowl
- Wooden spoon
- Spatula
Having the right equipment makes this dish feel effortless. A large skillet is important because the beef needs room to brown evenly—crowding the pan will steam the meat, and trust me, that changes everything about the flavor. The 9×13 dish gives plenty of space for layering so you get the right ratio of tots to meat mixture in every scoop. You don’t need anything fancy; I’ve made this in inexpensive cookware many times. A sturdy wooden spoon or spatula just helps break the beef apart and stir in all the flavors without slipping or bending.
Step-by-Step Instructions
When I start cooking this casserole, I always begin by browning the beef with the diced onions in my largest skillet. The sizzling sound and the savory aroma immediately tell me I’m on the right track. I make sure to break the meat into small pieces so every bite is flavorful, and I drain off any excess grease because too much moisture can make the casserole feel heavy. Once the beef looks browned and the onions are soft, I know it’s time to add the magic.
In the same skillet, I stir in the Thousand Island dressing, chopped pickles, mayonnaise, ketchup, mustard, onion powder, smoked paprika, salt, and pepper. The mixture transforms instantly into that unmistakable signature Big Mac taste, and the smell is incredible—tangy, creamy, savory, and warm all at once. I let it simmer for a couple of minutes so everything blends together, and every time, I’m tempted to grab a spoon and taste it right from the pan.
Next, I pour the mixture into the baking dish and sprinkle the shredded cheddar cheese evenly on top. The cheese creates a melty, delicious layer that fuses the meat and tater tots together. Then I arrange the tater tots over the entire dish in neat rows. This part always feels oddly satisfying, like I’m decorating a cheesy little potato blanket over the casserole.(See the next page below to continue…)
