To make barbecue pork ribs in the oven, preheat the oven to 300 degrees, peel off the membrane on the bony side, lay ribs on foil meaty side down, and cover with two layers of tightly crimped foil. Bake for 2 to 2 1/2 hours, then broil with barbecue sauce.
Tyler Florence from Food Network offers a more involved recipe, beginning by preheating the oven to 250 degrees Fahrenheit. Place the ribs on a baking sheet, and season them with salt, pepper and drizzled olive oil. Bake the ribs in the oven on low for 1 1/2 hours.
During the baking time, make the sauce by wrapping 2 bacon slices around 4 sprigs of fresh thyme tied with kitchen twine. In a large saucepan, heat a 2-count of olive oil over medium heat. Cook the bacon and thyme for 3 to 4 minutes to render the bacon fat. Add 1/2 onion and 3 smashed garlic cloves, and cook for 5 minutes. Add 2 tablespoons Dijon mustard, 2 tablespoons brown sugar, 1/4 cup molasses, 2 tablespoon red or white wine vinegar, 1 teaspoon ground cumin and 1 teaspoon paprika. Also add 1/4 cup peach preserves and 2 cups ketchup.
Stir the sauce and cook on low for 20 minutes. Baste the ribs three times, each time letting them cook for 30 minutes. Once the ribs are cooked, baste them again, and broil for five minutes on each side. This makes 4 to 6 servings of ribs.
