Method
Recipe notes
This unofficial recreation uses the chain's defining steam-griddle method: very thin perforated beef cooks over hydrated onions while the buns warm above it. The holes let steam pass through the patties, producing tender beef and soft buns rather than a crusty smash-burger finish.
Planning, storage, and serving
Storage and reheating
Refrigerate cooked patties and onions in a shallow covered container within 2 hours for up to 3 days. Reheat them covered in a skillet with a teaspoon of water until the beef reaches 165°F, then steam fresh buns over the top.
Make-ahead tips
Press, score, and perforate the beef up to 1 day ahead, separating layers with parchment and refrigerating them covered. Hydrate the onions shortly before cooking so they retain their full savory aroma.
What to serve with it
- - Crinkle-cut fries
- - Crisp dill pickle spears
- - Creamy cabbage slaw
Equipment needed
- - Large flat-top griddle or two wide skillets
- - Quarter sheet pan and parchment
- - Instant-read thermometer
Difficulty explained
The ingredients are simple, but rolling uniform thin patties and managing steam without overcrowding take a little coordination.

Pitfalls to Watch Out For
- Thick patties will not cook quickly enough under the buns; keep the beef close to 1/4 inch and verify 160°F.
- Draining all the onion water prevents the signature steam, while adding too much leaves the buns soggy; use only the measured cup.
- Hard-toasted artisan rolls overpower the tender slider texture, so choose very soft buns and warm rather than toast them.
Nutrition Context
- Two sliders provide a moderate portion of protein, while the buns, seasoning, pickles, and condiments contribute most of the sodium.
- Serving the sliders with slaw or another vegetable side adds freshness without changing their recognizable structure.
FAQ
Why punch holes in the patties?
The holes let onion steam pass through the thin beef so it cooks quickly and evenly without needing to flip.
Can I use fresh onions?
Yes. Mince them very finely and add a little water to the griddle because fresh onion alone may not create enough steam.
Do the patties need to be flipped?
No. When they are rolled to 1/4 inch and perforated, the covered steam cooks the top while the griddle cooks the bottom.
Can I freeze the uncooked patties?
Freeze the scored patties between parchment for up to 1 month, thaw overnight in the refrigerator, then separate and cook as directed.
How do I keep the buns from becoming soggy?
Use only the measured liquid, place buns on after the patties have cooked for 2 minutes, and serve the sliders immediately.
What sides pair best with this dish?
Good pairings include Crinkle-cut fries; Crisp dill pickle spears; Creamy cabbage slaw. Choose one or two based on how substantial you want the meal to be.
