Ingredients

• 1 large turnip, peeled and cubed
• 2 tablespoons butter
• 1 pinch salt and ground black pepper
• 2 large apples - peeled, cored, and diced
• 2 tablespoons brown sugar
• 1 pinch ground cinnamon
• Topping:
• 1/4 cup all-purpose flour
• 1/4 cup brown sugar
• 2 tablespoons butter, softened

Instructions

1. Preheat oven to 350 degrees F (175 degrees C). Grease an 8-inch casserole dish.
2. Place turnip into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, 15 to 20 minutes. Drain and transfer to a bowl.
3. Mash turnip, 2 tablespoons butter, salt, and pepper together until smooth.
4. Toss apples with 2 tablespoons brown sugar and cinnamon in a bowl.
5. Spread half the turnip mixture into the prepared casserole dish; top with half the apples. Repeat with remaining turnip mixture and apple mixture.
6. Mix flour, 1/4 cup brown sugar, and 2 tablespoons softened butter by hand in a bowl until mixture is an evenly coarse meal-texture; sprinkle over casserole.
7. Bake in the preheated oven until cooked through and bubbling, about 1 hour.
