Barley Free Orange-Pistachio Peach Oat Crisp
Juicy summer peaches meet bright citrus and crunchy pistachios in a bubbling, golden crisp that feels like pure comfort in a baking dish. The filling gets tossed with honey, fresh orange juice, orange zest, warm cinnamon, and a touch of ginger before arrowroot starch pulls it all into a glossy, jammy sauce as it bakes. The topping layers rolled oats, chopped pistachios, and almond flour with melted coconut oil and more honey, clumping into a deeply golden, nutty crust that shatters beautifully with every spoonful. For anyone navigating grain sensitivities, it's worth knowing that many packaged crisp toppings and baking mixes sneak in barley-derived ingredients — this one is built entirely from whole, straightforward components with no hidden grains to worry about. Almond flour steps in where wheat flour might typically appear, keeping the topping crisp and satisfying without compromising the texture at all. After about 35 to 40 minutes in the oven, the edges bubble and the kitchen smells like a citrus-spiced dream. Let it rest just long enough for the filling to thicken, then serve it warm — ideally with something cold and creamy on top.
