Step 1

Preheat oven to 400F (use convection if you have it), line a baking sheet with heavy-duty nonstick aluminum foil for easier cleanup if desired, add the sweet potatoes, evenly drizzle with the oil, salt, pepper, and toss with your hands to evenly coat.

Step 2

Bake for about 25 to 30 minutes, or until sweet potatoes are about 80% done, or well on their way to being done.

Step 3

While sweet potatoes are baking, prepare the topping.

Step 4

To a medium bowl, add all the ingredients, and fluff with a fork to combine until small pea to grape-sized clumps formed. If the mixture is too wet, add additional flour 1 tablespoon at a time as necessary until clumps can form. Remember not to stir like you're mixing up cake batter, just fluff it. Set topping aside.

Step 5

After sweet potatoes have roasted, transfer them to a 9x13-inch casserole or baking dish, or similar-sized.

Step 6

Evenly sprinkle the apples over the sweet potatoes in the casserole dish, evenly sprinkle with cinnamon, optionally evenly drizzle with oil, and evenly top with the topping mixture.

Step 7

Reduce the oven temp to 375F and bake for about 30 minutes, or until apples are as tender as desired, the topping is lightly golden browned and set, and sweet potatoes are cooked through. Serve immediately.
