Season the short ribs generously with salt and pepper on all sides.
In a large Dutch oven, heat olive oil over medium-high heat and brown the short ribs on all sides, about 3-4 minutes per side. Remove and set aside.
In the same pot, add onion, garlic, carrots, and celery. Sauté for 5-6 minutes until softened and fragrant.
Add the apple cider, thyme, and bay leaf, scraping up any browned bits from the bottom of the pot.
Return the short ribs to the pot, cover with lid, and transfer to the oven. Braise for 2.5 to 3 hours, or until the meat is tender and falling off the bone.
Remove from the oven and let rest for 10 minutes before serving.
Notes
Use heavy-bottomed Dutch oven for even heat distribution throughout braising.
Don’t rush the browning process as it develops deep flavor in the final dish.
For richer flavor, add a splash of balsamic vinegar during the last 30 minutes of cooking.
Let short ribs rest before serving for maximum juiciness and to allow sauce to thicken slightly.
