Can I make these sliders ahead of time?
Yes. Assemble the sliders, wrap in foil, and refrigerate up to 8 hours before baking. Add 5–10 minutes to the bake time if baking from cold.
What can I use instead of Muenster cheese?
Swiss, provolone, or additional cheddar work well. Choose a cheese that melts smoothly.
How do I make au jus from scratch instead of using a packet?
Simmer 1 cup beef broth with 2 tbsp butter, 1 tsp Worcestershire sauce, and seasonings for 5–10 minutes.
Can I freeze these sliders?
Freeze assembled (unbaked) sliders wrapped tightly for up to 1 month. Bake directly from frozen, adding 10–15 minutes to bake time.
How thin should the roast beef be sliced?
Ask the deli counter for thin slicing (about 1/8 inch). Thin slices meld better with the cheese and absorb the butter sauce.
