No grill needed for these succulent baby back ribs! They're rubbed with hot paprika, fennel seeds, and fresh herbs, then roasted, broiled, and finished with a garlicky white-balsamic glaze.
Line a baking sheet with parchment-lined foil. Stir together oil, 4 teaspoons salt, 1 teaspoon pepper, paprika, fennel seeds, sage, thyme, and rosemary. Rub mixture all over ribs. Cover; let stand at least 1 hour, or refrigerate up to overnight.
Preheat oven to 325 degrees. Roast ribs, uncovered, until meat is tender, 2 hours. (Ribs can be allowed to cool completely at this point and stored, covered, in refrigerator up to 3 days.) Switch oven to broil, with a rack 6 inches from heating element. Stir together vinegar and garlic; season with salt and pepper. Brush ribs with half of glaze. Broil until crisp, 1 to 2 minutes. Brush with remaining glaze, if desired. Cut into pieces and serve, alongside potato salad.
To prevent ribs from becoming chewy after cooking, remove the thin, tissuey membrane from the undersides: Slide the tip of a knife between the bone and the membrane at one end, then pull it back. It should come off in one piece.
