Peach Crisp Recipe Oatmeal Gluten Free: Warm Spiced Topping with Almond Flour Base

This gluten-free peach crisp delivers all the comfort of the classic without the wheat. The almond flour base creates a perfectly crisp topping that pairs beautifully with juicy, warm peaches.

I developed this recipe to capture that nostalgic dessert feeling while keeping it naturally gluten-free. The oatmeal adds texture, while cinnamon and nutmeg bring warm spice to every bite.

You’ll love how the peaches soften into a bubbly filling beneath a golden, crunchy topping. It’s simple to prepare yet impressive enough for company.

Serve it warm with vanilla ice cream or whipped cream for the ultimate treat. Here’s how to make it.

Ingredients for Peach Crisp Recipe Oatmeal Gluten Free

Ripe peaches and a crunchy almond-oat topping make this dessert unforgettable. Simple, warm, and naturally gluten-free.

Peaches are the star here. Farmers market peaches in late summer are unbeatable—look for fragrant, slightly soft fruit. If they’re rock-hard, they won’t soften enough. For almond flour, Bob’s Red Mill is my go-to (widely available at Whole Foods and most grocery stores). The oats need to be certified gluten-free to keep this dish safe for everyone—Quaker makes a reliable option.

No almond flour? Sunflower seed flour works as a 1:1 swap (great for nut allergies). Brown sugar can be coconut sugar at the same amount. For a vegan version, coconut oil replaces butter nicely. The cornstarch? Arrowroot powder at the same quantity gets the job done. Fresh peaches out of season? Frozen sliced peaches (thawed and drained) work in a pinch.

Assemble this just before baking for the crispiest topping. Leftovers keep 3-4 days at room temperature (the oats soften over time). Best eaten warm—reheat individual portions in a 350°F oven for 10 minutes. Doubles easily for a crowd.

Step-by-Step Instructions for Peach Crisp with Oatmeal and Almond Flour

Here’s the method I use for a foolproof crisp with a golden, spiced topping every time.

Step 1: Prepare the Peach Filling

Peel, pit, and slice all 6 whole Peaches into a large bowl. I like to cut them into thick wedges so they hold their shape during baking. Toss the peaches with the 0.25 cup Granulated Sugar, 2 tbsp Cornstarch, 1 tsp Vanilla Extract, and 1 tbsp Lemon Juice.

The cornstarch thickens the juices as the peaches bake, creating a luscious filling rather than a watery mess. The lemon juice brightens the flavor and keeps the peaches from browning too quickly. Let this mixture sit for 10 minutes while you prepare the topping.

Step 2: Mix the Crisp Topping

In a separate bowl, combine the 1.5 cups Almond Flour, 1 cup Old-Fashioned Rolled Oats, 0.75 cup Brown Sugar, 1.5 tsp Ground Cinnamon, 0.25 tsp Ground Nutmeg, and 0.25 tsp Salt. Stir until evenly mixed—the almond flour gives this topping a rich, nutty base.

Add the 0.5 cup Unsalted Butter (cold and cubed) to the dry mixture. Use your fingers or a fork to work the butter in until the mixture resembles coarse crumbs with some pea-sized clumps. This texture ensures a crispy, crumbly topping after baking.

Step 3: Assemble and Bake

Transfer the peach filling to a greased 8×8-inch or 9×9-inch baking dish, spreading it evenly. Sprinkle the topping mixture over the peaches in an even layer, pressing down lightly to help it adhere. Don’t pack it too tightly—you want the topping to crisp up.

Bake at 375°F for 35-40 minutes, or until the filling is bubbly and the topping is golden brown. I start checking at 30 minutes to prevent over-browning. If the top browns too quickly, tent loosely with foil.

Step 4: Cool Slightly and Serve Warm

Remove the crisp from the oven and let it cool for 10-15 minutes. This resting time allows the filling to thicken slightly, making it easier to serve. The aroma of warm cinnamon and nutmeg will fill your kitchen—it’s hard to resist digging in right away!

Serve warm in bowls, ideally with a scoop of vanilla ice cream or a dollop of whipped cream. The contrast of the crispy, spiced topping with the tender, juicy peaches is what makes this dish so irresistible. Leftovers reheat beautifully in the oven at 350°F for 10 minutes.

Essential Equipment for peach crisp recipe oatmeal gluten free

Mixing Bowls

A good set of nested mixing bowls is essential for this recipe. I recommend Pyrex glass bowls because they’re sturdy, non-reactive, and let you see your ingredients clearly. You’ll need at least a 2-quart bowl for the topping mixture.

Baking Dish

An 8×8-inch or 9×9-inch baking dish works perfectly for this crisp. I prefer stoneware from Le Creuset – it distributes heat evenly and looks beautiful on the table. A 9×13-inch dish works too if you’re doubling the recipe. 💛

Measuring Tools

Accurate measurements matter in baking. I use OXO Good Grips measuring cups and spoons – they’re affordable, durable, and the magnetic set stays organized. A kitchen scale helps too for precise almond flour measurements.

Pastry Blender

For the crispiest topping, a pastry blender works better than your fingers for cutting in the butter. The RSVP Endurance model has comfortable handles and strong wires. If you don’t own one, two forks in a scissor motion works in a pinch.

Peeler and Knife

A sharp Y-peeler makes quick work of peach skins. I like the OXO Soft Grip version. Pair it with a 8-inch chef’s knife for slicing peaches – a Wüsthof or Victorinox will serve you well for years.

Cooling Rack

Always cool baked goods on a wire rack to prevent soggy bottoms. A simple stainless steel rack works perfectly. Let your crisp rest for 10-15 minutes before serving to allow the filling to set properly. ✨
