Preparation
Step 1
Position rack in center of oven and preheat to 400°F. Combine parsnips, water, salt and bay leaf in medium saucepan. Cover and simmer until parsnips are very tender, about 15 minutes. Drain, reserving 1 cup cooking liquid; discard bay leaf. Puree parsnips in processor until smooth. (Can be made 4 hours ahead. Cover; let stand at room temperature.)
Step 2
Butter 8-cup soufflè dish; dust with flour. Melt 1/4 cup butter in large saucepan over medium-high heat. Add 1/4 cup flour and stir 2 minutes. Gradually whisk in 1 cup cooking liquid. Boil until smooth and thick, whisking frequently, about 3 minutes. Remove from heat. Stir in cheese, sage and parsnip puree. Season with salt and pepper. Whisk in yolks.
Step 3
Using electric mixer, beat egg whites and cream of tartar in large bowl until stiff but not dry. Gently fold into parsnip mixture in 3 additions. Transfer to prepared dish. Bake until soufflè is puffed and top is golden brown, about 40 minutes. Serve immediately.
