Heat oil in a large skillet over high heat; reduce to medium. Cook onions with sugar and salt, stirring occasionally, until onions brown, 20 to 25 minutes. Add a few tbsp water as you cook to keep onions from sticking or burning. Fill a medium stockpot 3/4 full with cold water. Add potatoes and parsnips; bring to a boil over high heat. Reduce heat and simmer until potatoes and parsnips are fork-tender, 20 to 25 minutes, then drain. Beat 1/4 of potato-parsnip mixture and 3 oz broth in a mixing bowl with an electric mixer on medium speed until smooth. Repeat, alternating between potato-parsnip mixture and broth, until you’ve incorporated all. Fold in onions, cheese and thyme, and serve.
