Short Rib Grilled Cheese with Smoked Gouda and Pickled Onions

Leftover braised short ribs make the most decadent grilled cheese imaginable. Shredded beef folded with its reduced pan jus, layered with smoky melted Gouda and bright magenta pickled onions, then griddled in bone-marrow butter until the sourdough shatters. One sandwich, roughly twenty minutes, and every bite delivers tender beef fibers, glossy cheese and a crunch you will hear across the kitchen.

This is the grilled cheese for the night after braise night. The hard work is already done: the short rib has spent hours in red wine, the pan jus is reduced and intense, and all that remains is assembly and a hot griddle.

The method is deliberately simple. Shred the beef, moisten it with jus, drain the onions, butter the bread generously, and cook at a steady 365°F so the marrow butter browns while the Gouda has time to melt completely into the meat.

The pickled onions are not decoration; their sharp, vinegar brightness cuts through the richness of beef and smoked cheese and keeps each bite balanced. The result is a sandwich with real structure: a crackling crust, distinct layers, and a cross-section worth turning the camera on.

Ingredients

Why this recipe works

The method works because it treats the braised beef as a filling that needs moisture management, not more cooking. Shredding by hand creates irregular strands that interlock with melted cheese instead of sliding out, and folding in the reduced pan jus rehydrates the fibers while concentrating the wine-braise flavor.

Draining the pickled onions matters more than it sounds: vinegar carried into the sandwich steams the crumb and weakens the crust from within, so a minute in a strainer protects the texture you worked for.

The 365°F griddle temperature is the second pillar. Smoked Gouda needs several minutes to melt fully, and sourdough needs the same window to brown through a coating of marrow butter.

At that temperature both finish together: the butter foams and fries the bread into deep-gold crispness while the cheese flows into the beef, and the filling heats through to a safe 145°F. Building with cheese above and below the filling anchors the layers, so the sandwich slices cleanly and stretches instead of collapsing.

Notes and substitutions

Choose a boneless short rib or lift the meat off the bone; six ounces is enough for one generous sandwich. The jus should be reduced and glossy, almost syrupy, since watery jus makes the filling weep. Quick-pickled red onions take only minutes to make if none are on hand: thin-slice a red onion, cover with hot vinegar, a pinch of sugar and salt, and rest for thirty minutes.

Bone-marrow butter gives the crust its beefy depth, but softened regular butter works well if that is what is available. Use a dense, sturdy sourdough cut about an inch thick; airy bread compresses under the filling. A cast-iron skillet or flat griddle holds temperature evenly, and an instant-read thermometer confirms both the 365°F surface and the 145°F filling temperature. A serrated knife and a patient sawing motion finish the job.

• Bone-marrow butter: Use softened regular butter or half butter whisked with a spoonful of beef drippings; the crust browns the same way at 365°F.
• Smoked Gouda: Provolone, young Gruyère or sharp white cheddar melt well; add a pinch of smoked paprika to keep the smoky note.
• Braised short rib: Any leftover braised beef works, from pot roast to barbacoa; warm it gently with a spoonful of its liquid before shredding.
• Quick-pickled red onions: Thin-sliced raw red onion tossed with a splash of vinegar and a pinch of sugar for 10 minutes gives a similar bright crunch.
