Make this recipe a recipe that people in that category can eat. categories: ['dairy_free'], recipe: heat the butter in a large heavy skillet until it is foaming. add the onion quarters in quantities that fit easily in the pan. toss the onions over moderate heat until well coated on all sides. transfer to a shallow baking dish. sprinkle the onions with salt and pepper. bake in a preheated 350 degree f oven for 1 hour and 15 minutes, turning the onion every 20 minutes during roasting.

Target recipe: preheat oven to 250° (not a mistake). peel onions and cut each in half through the stem end, then cut each half into quarters; cut the quarters in half crosswise; place onions into a bowl. to the onions, add olive oil, balsamic vinegar, honey, and pepper; toss to coat onions well. pour onto a small baking sheet or into a 9-inch ovenproof skillet (the onions should be piled onto the pan, not spread in a single layer); set the bowl aside. cook the onions for a total of 3 hours; take them out every 30 minutes and transfer back to the bowl to mix thoroughly before rearranging on the baking sheet and putting back in the oven--this keeps any part of the onion slices from drying out and becoming crispy. will keep indefinitely in the refrigerator.
