Why this recipe works: Short ribs are all about the meat and the sauce, so to get a deeply flavored sauce, we first focused on the bones, which we knew were one key to flavor. Not wanting to roast the bones in the oven, we turned to the microwave, which helped in two ways: It rendered out unwanted fat (and short ribs are notoriously greasy), and it gave the bones a roasted flavor which in turn deepened the sauce during the long cooking time. One taste of these long-cooked ribs with their dark glossy sauce and you’ll be glad you put your microwave and skillet to work first.

Ingredients

2tablespoonsvegetable oil
2onions, chopped medium

3tablespoonsall-purpose flour
2cupsdry red wine
2tablespoonsbalsamic vinegar
2cupslow-sodium chicken broth

2tablespoonsminced fresh parsley
Instructions
Arrange beef bones in a dish and microwave (in batches, if microwave is small) until well browned, 10 to 15 minutes; transfer to slow cooker.
Dry short ribs with paper towels and season with salt and pepper. Heat 1 tablespoon oil in 12‑inch skillet over medium-high heat until just smoking. Brown half of short ribs well on all sides, 7 to 10 minutes; transfer to slow cooker. Repeat with remaining tablespoon oil and remaining short ribs; transfer to slow cooker.
Add onions, carrot, celery, tomato paste, and thyme to fat in skillet and cook over medium-high heat until onions are softened and lightly browned, 8 to 10 minutes. Stir in flour and cook for 1 minute. Slowly whisk in wine and vinegar, scraping up any browned bits and smoothing out any lumps. Bring to simmer and cook until reduced to 1 cup, about 5 minutes; transfer to slow cooker.
Stir broth and bay leaves into slow cooker. Cover and cook until beef is tender, 9 to 11 hours on low or 5 to 7 hours on high.
Transfer short ribs to serving platter and tent loosely with aluminum foil. Let braising liquid settle for 5 minutes, then remove fat from surface using large spoon. Strain braising liquid, discarding solids, and season with salt and pepper to taste. Stir in parsley. Spoon 1 cup sauce over short ribs and serve with remaining sauce.
