Gluten Free Orange-Pistachio Peach Oat Crisp
Juicy summer peaches meet bright citrus and crunchy pistachios in a dessert that feels genuinely special without requiring any complicated technique. The filling gets tossed with fresh orange zest, orange juice, warm spices, and arrowroot starch, which thickens everything into a glossy, bubbling fruit base as it bakes. The topping comes together with rolled oats, almond flour, and chopped pistachios bound by honey and melted coconut oil — no wheat flour anywhere in sight, so it works beautifully for anyone avoiding gluten without any awkward substitutions that compromise texture. That combination of almond flour and oats gives the crisp a genuinely satisfying crunch that holds up even as it soaks in the peachy juices below. Everything bakes at 350°F until the topping turns deep golden and the edges start to bubble, filling your kitchen with a warm, spiced citrus aroma that is honestly hard to resist. A ten-minute rest after it comes out of the oven lets the filling thicken just enough so every scoop holds together perfectly. Serve it as-is or with your favorite topping — this one is a crowd-pleaser that nobody will suspect was built around a dietary need.
