Place all the ingredients in a large mixing bowl and toss well to combine.
2 pounds apples*, ¼ cup pure maple syrup, 1 Tablespoon lemon juice, 1 Tablespoon cornstarch, 1 teaspoon ground cinnamon
Transfer the mixture to a 9x13 inch baking dish. If any liquid remains in the bottom of the bowl, pour it over the top.
Bake, uncovered, for 25 to 30 minutes until the apples are tender when pierced with a fork. Serve warm.
Notes
* Choose firmer varieties for best results. I recommend using a sweet-tart variety such as Granny Smith, Pink Lady, Honeycrisp, or SweeTango, which is shown in the photos.Leftovers can be refrigerated in an airtight container for 3 to 4 days. Reheat in a microwave or oven.
