Servings: Serves 4-6
Preheat oven to 375°. Heat olive oil in a large Dutch oven or ovenproof pot over medium heat. Add carrots, celery, garlic, and onion; cook, stirring often, until softened, 10 to 12 minutes. Increase heat to medium-high, and add chicken, 3/4 teaspoon salt, and pepper; cook, stirring occasionally, until no longer pink, 6 to 8 minutes. Add wine and cook until absorbed, 1 to 2 minutes. Stir in broth, thyme, bay leaf, sweet potato, and turnip; bring to a boil. Reduce heat to medium-low, and simmer until vegetables are almost tender, about 20 minutes.
In a small bowl, combine cornstarch and 2 tablespoons water, then stir into simmering stew. Cook, stirring often, until thickened, about 5 minutes. Meanwhile, to make biscuit batter, in a large bowl, combine both flours, baking powder, baking soda, and 1/2 teaspoon salt. Add canola oil and buttermilk; stir until just combined. Drop batter on top of stew to form 6 biscuits, then transfer pot to oven and bake until biscuits are just golden and cooked through, about 20 minutes.
Remove from oven. Sprinkle cheese over biscuits. Return to oven; bake until cheese is bubbly, about 10 minutes. Ladle stew and biscuits into bowls; serve immediately.
