From the MyKitchenBank Kitchen

Tender beef short ribs braised low and slow with onions, garlic, and red wine vinegar until fall-apart tender. The meat is then shredded and piled onto thick-cut, toasted sourdough with its rich braising liquid. The slow cooker does most of the work, yielding a deeply savory, restaurant-quality sandwich that's worth the wait.

Steps

Before you start

Trim any large pieces of excess surface fat from the short ribs before starting.
Have a 5- to 6-quart slow cooker ready and on hand.
Read the recipe through—the braising takes 6 to 7 hours, so plan accordingly.
Prep all ingredients before browning to keep the workflow smooth.

1
Prep the ingredients
- Trim any large pieces of excess surface fat from the short ribs, leaving a thin layer for flavor.
- On a cutting board, dice the onions into roughly ½-inch pieces.
- Mince the garlic cloves.
- Have all other ingredients measured and ready.

Tip: Prep all ingredients before starting to cook so you can move quickly through browning and building the slow cooker.
2
Brown the short ribs
- Heat a large heavy-bottomed skillet over medium-high heat until very hot, about 2 minutes.
- Working in batches to avoid crowding, add short ribs and brown on all sides until deeply golden (don't worry about cooking through), about 3 minutes per side or 9–12 minutes total depending on the size of your ribs.
- Transfer the browned ribs to a plate.

Ready when: Short ribs are golden brown on all sides
Tip: Don't move the ribs around too much while browning—let them sit in the hot pan for color development. Leave at least 1 inch between ribs for even browning.
3
Sauté the aromatics
- In the same skillet (do not wash it—the browned bits, or fond, add deep flavor), add the diced onions and cook over medium heat, stirring occasionally, for about 3 minutes until they soften slightly.
- Add the minced garlic and stir for 1 minute more until fragrant.
- Transfer the onions and garlic to your slow cooker.

Ready when: Onions are softened and beginning to become translucent; garlic is fragrant
Tip: Scrape up the fond from the bottom of the pan as you stir to incorporate all that flavorful browned material into the dish.
4
Assemble in the slow cooker
- Layer the browned short ribs on top of the onions and garlic in the slow cooker.
- Pour the beef broth and red wine vinegar over the meat.
- Add the Worcestershire sauce.
- Sprinkle the salt, black pepper, dried thyme, and red pepper flakes evenly over everything.
- Gently stir the liquid to combine the seasonings, then cover the slow cooker.

Tip: Leave 2–3 inches of space at the top of the slow cooker to prevent overflow. The liquid should come partway up the ribs, not fully submerge them.
5
Braise the short ribs
- Cover and set the slow cooker to low.
- Cook for 6 to 7 hours.
- The short ribs are done when the meat is incredibly tender—it will pull away from the bone with very little resistance, and a fork should pass through the thickest part easily.
- If you're in a hurry, cook on high for 3 to 4 hours, though low and slow yields the most tender result.
- The braising liquid will reduce slightly and take on deep, rich color.

Ready when: Meat is extremely tender and pulls away from bone with minimal resistance; a fork passes through easily
Tip: Resist the urge to lift the lid frequently—each time you do, you add about 15 minutes to the cooking time. The slow cooker will do the work without your help.
6
Shred the meat
- Remove the lid and let the slow cooker sit for 5 to 10 minutes so the meat cools enough to handle comfortably.
- Using tongs, carefully lift the short ribs from the slow cooker and transfer to a cutting board or large shallow bowl.
- Once cool enough to handle, use two forks to pull the meat away from the bones, discarding the bones and any large pieces of fat.
- Return all shredded meat to the slow cooker with its braising liquid.
- Taste the liquid and adjust seasoning with additional salt, vinegar, or pepper as needed.

Ready when: Meat pulls cleanly from bone; no pink is visible at the bone
Tip: The braising liquid is precious—don't discard it. A pinch more vinegar can brighten the flavors; more salt deepens them. Taste and adjust to your preference.
7
Toast the sourdoughOven 500°F / 260°C
- While the meat is braising or cooling, slice the sourdough loaf into ½-inch-thick slices.
- Lightly brush each slice with softened butter if you want extra richness (optional but recommended).
- Arrange slices on a baking sheet in a single layer and broil 4 inches from a preheated 500°F (260°C) broiler for 2 to 3 minutes per side until golden and crisp.
- Alternatively, heat a heavy skillet over medium-high heat, add a thin film of butter or oil, and toast the bread slices 2 to 3 minutes per side until golden.
- Work in batches to avoid crowding.

Ready when: Bread is golden brown and crisp on both sides
Tip: Toast the bread as close to serving time as possible—if toasted too far in advance, it will absorb moisture and lose its crispness.
8
Build and serve
- Place one slice of toasted sourdough on a serving plate or in a sandwich basket.
- Top with about 4 to 5 ounces (115–140 grams) of shredded short rib meat—roughly a heaping ½-cup measure.
- Spoon 2 to 3 tablespoons of the hot braising liquid over the meat to add moisture and flavor (this is not a dry sandwich).
- Top with a second slice of toasted sourdough.
- Serve immediately while the bread is warm and crisp.

Tip: Serve with traditional toppings like horseradish cream, pickled vegetables, crispy onions, or fresh herbs such as parsley or thyme on the side.

Tips

Brown the short ribs if you have time—it takes only 12 minutes and builds a deeper, more complex braising base. Skipping this step shortens active time but reduces depth of flavor.
Adjust the braising liquid to taste just before serving. Salt and vinegar are the key seasonings; you may need to add more of either depending on your broth and personal preference.
For extra richness, stir a spoonful of horseradish cream or a dollop of Dijon mustard into the braising liquid just before serving, or offer it as a topping.
This recipe is naturally made-ahead friendly—braised meats improve after a day in the fridge, so make it the day before serving for even deeper flavor.

Make ahead

Braised meat actually improves with time as flavors deepen overnight. The complete braised short ribs (in their liquid) can be made up to 3 days ahead. Cool completely, store in an airtight container in the refrigerator, and reheat gently on low heat in the slow cooker (covered, 30–45 minutes) or in a pot on the stovetop. You can also freeze the braised meat and liquid for up to 3 months; thaw in the refrigerator overnight before reheating.

Storage & reheating

Room temperature: Not recommended (food safety); serve and eat immediately. Refrigerator: Store leftover braised short ribs in their liquid in an airtight container for up to 4 days. Reheat gently over medium heat in a pot, or in the slow cooker on low (covered) for 30–45 minutes until warmed through. Freezer: Cool completely, then transfer to a freezer-safe container or heavy-duty zip-top bag for up to 3 months. Thaw overnight in the refrigerator before reheating.

Substitutions

beef short ribs, bone-in → Beef chuck roast or beef brisket. Both are forgiving braising cuts with good marbling. Chuck will break down more quickly (5–6 hours); brisket will take longer (7–8 hours). Cube the chuck into 2-inch pieces for faster cooking if desired.
red wine vinegar → Apple cider vinegar or balsamic vinegar. Both provide acidity and complementary flavor. Use the same amount. Balsamic adds slight sweetness; cider vinegar is milder and slightly fruity.
beef broth → Beef stock or a mix of beef broth and dry red wine (1½ cups broth + ½ cup wine). Stock is richer; wine adds depth but increases alcohol flavor. Omit wine if not desired.
sourdough bread loaf, large → Crusty Italian bread, ciabatta, or brioche buns. Sourdough's tang is classic, but any sturdy bread can work. Brioche will be softer and slightly sweet; use fewer toppings so the bread doesn't fall apart.
