Step 1: Heat olive oil over medium-high heat in a large skillet. Brown the ribs well on both sides, turning them a few times, about 10 minutes total. Brown them in batches if necessary, to avoid crowding them in the pot.
Step 2: Transfer ribs to the liner of your crockpot.
Step 3: Reduce heat under skillet to medium. Add onion, carrot and celery to skillet and cook for 5 to 6 minutes, stirring frequently to avoid burning. Stir in garlic, rosemary and paprika and cook until fragrant, about 45 seconds. Add wine, scraping up any brown bits.
Step 4: Pour wine and onion mixture and tomatoes and their juices over the ribs, working them in around the meat with a wooden spoon.
Step 5: Tuck the bay leaf into the tomatoes. Cover the pot and cook on low for 4-6 hours (depending on how hot your crockpot runs).
Step 6: Mix cornstarch and water in a small bowl and pour into crockpot, stirring it into the juices. Let juice thicken a bit and then serve ribs with sauce.
