01 - Preheat oven to 400°F. Scrub sweet potatoes, pierce several times with a fork, and place on a lined baking sheet. Bake for 45–50 minutes, or until tender.
02 - While sweet potatoes bake, melt butter in a skillet over medium heat. Add diced apples, ground cinnamon, ground nutmeg, and salt. Sauté for 5–6 minutes until apples soften slightly.
03 - Stir in chopped walnuts and maple syrup. Cook for an additional 2 minutes until heated through, then remove skillet from heat.
04 - Once sweet potatoes are cool enough, slice each down the center and gently open. Fluff interior flesh with a fork.
05 - Spoon apple-walnut mixture evenly into sweet potatoes. Garnish with dried cranberries and chopped parsley if desired.
06 - Serve warm as a main or robust side dish.
