Why You’ll Love This Gluten-Free Peach Crisp

This Gluten-Free Peach Crisp highlights everything we love about summer baking:

• It uses simple pantry ingredients.
• The topping is perfectly crumbly and golden.
• It’s easy to customize for dairy-free or nut-free diets.
• It tastes even better with a scoop of ice cream melting into the warm fruit.

Unlike cobblers that feature a cake-like topping, this crisp focuses on texture contrast. The fruit becomes jammy and tender while the topping bakes into a crunchy, buttery layer.

Ingredients You’ll Need

Below are the key components that make this crisp so delicious. Exact measurements are listed in the recipe card at the bottom.

For the Crisp Topping

Gluten-Free Rolled Oats
Use certified gluten-free oats to ensure the dessert stays completely gluten-free. Old-fashioned rolled oats provide the best texture.

Sliced Almonds
Almonds add a rich, nutty crunch that pairs beautifully with peaches. You can lightly toast them beforehand for even deeper flavor.

Gluten-Free 1:1 Baking Flour
A quality all-purpose gluten-free flour blend helps bind the topping and gives it structure.

Brown Sugar & Granulated Sugar
Brown sugar adds moisture and caramel notes, while granulated sugar enhances sweetness and crispness.

Vanilla Extract
A small amount deepens the flavor of the topping.

Butter
Cold butter is essential for that crumbly, bakery-style topping. It creates those irresistible crisp clusters.

Salt
Balances the sweetness and enhances the nutty flavor.

For the Peach Filling

Fresh Peaches
Look for peaches that are fragrant and slightly soft to the touch. The riper they are, the sweeter your crisp will be.

Cornstarch
Helps thicken the juices as the peaches bake.

Lemon Juice
Brightens the flavor and prevents the filling from tasting flat.

Granulated Sugar
Enhances the natural sweetness of the peaches.

Cinnamon & Nutmeg
Warm spices that complement the fruit without overpowering it.

How to Easily Peel Peaches

Peeling peaches doesn’t have to be difficult. If the skins don’t slip off easily with a knife, try blanching:

1. Bring a large pot of water to a boil.
2. Carefully lower 3–4 peaches into the water for about 2 minutes.
3. Transfer them to a bowl of ice water.
4. Once cooled, the skins should slide off effortlessly.

This extra step saves time and gives your filling a smoother texture.

How to Make Gluten-Free Peach Crisp

Here’s a quick overview before you scroll down to the full recipe card.

Step 1: Prepare the Topping

In a food processor, pulse most of the oats with the gluten-free flour, sugars, vanilla, water, and salt. Pulse just until combined.

Step 2: Add Butter and Almonds

Add the cold butter pieces and half of the sliced almonds. Pulse until the butter resembles small peas and the mixture looks crumbly.

Step 3: Finish the Topping

Stir in the remaining oats and almonds with a couple of quick pulses. Set aside.

Step 4: Make the Filling

In a large bowl, gently mix the sliced peaches with cornstarch, lemon juice, sugar, cinnamon, and nutmeg until evenly coated.

Step 5: Assemble

Spread the peach mixture into a 9×13-inch baking dish. Sprinkle the topping evenly over the fruit.

Step 6: Bake

Bake at 400°F for 25–30 minutes, or until the topping is golden brown and the filling is bubbling around the edges. Let it cool for at least 15 minutes before serving.
