Tips & Notes

Pro tips

Don't oversaturate the bun—dip quickly or brush with au jus to avoid sogginess; serve with extra gravy for dipping on the side.
Warm the deli roast beef in the au jus rather than separately to infuse flavor and save a pan.
Toast the buttered buns lightly in a skillet to add crunch and create a barrier against moisture absorption.
Use poppy seed buns as specified—their slight sweetness balances the savory au jus and cheese sauce better than plain buns.

Substitutions

Au jus mix → beef broth or beef consommé (use 2 cups, skip the packet)
Canned cheddar cheese sauce → shredded sharp cheddar melted with a splash of milk (more homemade flavor)
Deli roast beef → thinly sliced roasted beef or rotisserie beef (fresher quality)
Poppy seed buns → hoagie rolls or regular hamburger buns (texture and flavor will differ slightly)
