Prepare salsify by rinsing thoroughly. Peel and cut into 2” pieces. (You may want to use gloves because salsify tends to be sticky.) Place salsify in a large mixing bowl.
Add olive oil, lemon zest, salt and pepper to the bowl. Toss to evenly coat the salsify.
Transfer salsify to a parchment lined sheet tray and roast for 30 minutes.
Remove salsify from the oven and sprinkle with parsley.
