Ingredients

The beef is fully cooked — warm it, don't simmer it. Costco's Cuisine Solutions sirloin is sous-vide and ready to eat; 30–60 seconds in the hot jus is all it needs. Boil it and lean grass-fed beef goes gray and chewy. The jus does double duty: it warms the meat, and it's your dipping cup.

Easier, if you like

The whole point is the shortcut: Costco Cuisine Solutions Sliced Grass-Fed Beef Sirloin is fully cooked, so dinner is really just make jus, warm beef, toast rolls. Any pre-cooked sliced roast beef (deli or packaged) works too.
Skip the from-scratch jus with a packet of au jus gravy mix, or just warm the beef in good beef broth spiked with a splash of Worcestershire.

Method

Cook's notes

Why pre-cooked beef shines here: French dip is all about thin, tender beef and good jus — and the sous-vide sirloin gives you both in minutes, with no roast to cook and slice.

Make the jus richer with a teaspoon of beef base (like Better Than Bouillon) or a splash of red wine simmered in.

Provolone is classic; Swiss or white American also melt beautifully. A schmear of horseradish sauce or Dijon on the roll cuts the richness.

Caramelized onions are a great addition — cook them low and slow in the butter before the broth goes in.

Grass-fed sirloin is lean, so each bite leans on the jus to stay moist — don't skip the dip.

Make it gluten-free

Gluten-free: use gluten-free rolls, tamari in place of soy sauce, a gluten-free Worcestershire, and a gluten-free beef broth. The beef and cheese are already gluten-free.
