A warm, comforting gluten-free apple crisp featuring a thick, juicy apple filling and a tender, buttery oat crumble topping. This recipe uses simple pantry ingredients and a two-stage baking process to ensure perfect texture and flavor.
Use Golden Delicious apples for best texture and balanced flavor; for juicier apples like Honeycrisp, add an extra ½ to 1 tablespoon of cornstarch., Certified gluten-free oats are recommended to avoid cross-contamination., You can substitute vegan butter or solid coconut oil for a dairy-free or vegan version, noting coconut oil may add a slight coconut flavor., Allow the crisp to cool 30-60 minutes after baking to set the filling and avoid soggy topping., Reheat leftovers gently at 300°F for about 20 minutes; to re-crisp topping, bake uncovered at 350–375°F for 8–12 minutes., To freeze, bake first, cool, wrap tightly, and freeze for up to three months. Bake from frozen with additional cooking time., Do not wrap baked crisp in plastic wrap at room temperature to preserve topping texture.
