Healthy Peach Crisp Gluten Free with Almond and Oat Crumble
Some desserts just feel like summer in a bowl, and this healthy peach crisp gluten free recipe is exactly that. Juicy, caramelised peaches bubbling beneath a golden, nutty crumble topping that shatters just slightly when you press a spoon through it. This version is built for anyone who loves a proper fruit crisp but wants something genuinely lighter, not just a tweaked version of a butter-heavy classic. It cuts refined sugar significantly, swaps out traditional flour entirely, and leans on wholesome ingredients that actually add nutritional value. Gluten free bakers, health-conscious dessert lovers and anyone mid-peach season with a fruit bowl to use up will find this recipe hits every note.
The filling relies on ripe fresh peaches tossed with a small amount of pure maple syrup, a squeeze of lemon juice and a pinch of cinnamon and ginger. Ripe peaches bring natural sweetness that means you need very little added sugar at all. Arrowroot powder thickens the juices as they cook, creating that gorgeous jammy texture without any cornstarch or refined thickener. For the crumble topping, certified gluten free rolled oats form the backbone, delivering soluble fibre and that satisfying chewy-crisp contrast. Almond flour adds healthy fats, a mild nuttiness and extra protein, while coconut oil replaces most of the butter to keep saturated fat lower. A small amount of chopped walnuts gives crunch and adds omega-3 fatty acids. The whole topping is sweetened with just two tablespoons of coconut sugar, which has a lower glycaemic index than white sugar and a subtle caramel flavour that works beautifully with peaches.
When this comes out of the oven, the topping is deeply golden and crisp, with the peach filling thick and syrupy, just beginning to bubble up around the edges. The aroma of cinnamon, toasted oats and warm fruit is genuinely hard to resist. Texture-wise you get that classic crisp contrast, soft yielding fruit underneath and a crumbly, slightly crunchy topping above. A scoop of plain Greek yogurt or a dairy-free coconut yogurt alongside keeps things cool and creamy without loading on extra calories the way ice cream would. For a slightly more indulgent finish, a drizzle of almond butter over the warm crisp adds richness and protein in a single move. This is also genuinely lovely served warm for breakfast the next day with a spoonful of yogurt stirred in.
From a dietary angle, each serving comes in under 220 calories with around 4 grams of fibre and 5 grams of protein, making it one of the most nutritionally complete fruit crisps you can make at home. Using certified gluten free oats means it is safe for those with coeliac disease or gluten sensitivity, not just those avoiding gluten by preference. The recipe contains no refined sugar at all, relying entirely on maple syrup, coconut sugar and the natural sweetness of the peaches themselves. Almond flour and walnuts contribute vitamin E, magnesium and heart-healthy unsaturated fats. Peaches themselves bring vitamins A and C, potassium and antioxidants including beta-carotene and chlorogenic acid. This is a dessert that earns its place at the table not just because it tastes wonderful, but because it genuinely supports the kind of eating most of us are trying to do more of. Make it on a Tuesday evening as a quick weeknight treat, or bake it ahead for a gathering and watch it disappear faster than anything else on the table.
Ingredients
- 700 g fresh ripe peaches (about 5 to 6 medium peaches, peeled, stoned and sliced 1cm thick)
- 1 tbsp pure maple syrup (for the filling)
- 1 tbsp fresh lemon juice
- 1.5 tsp arrowroot powder (or tapioca starch)
- 0.5 tsp ground cinnamon (for the filling)
- 0.3 tsp ground ginger
- 1 pinch fine sea salt (for the filling)
- 120 g certified gluten free rolled oats (not quick oats)
- 60 g almond flour (blanched and finely ground)
- 40 g raw walnut pieces (roughly chopped)
- 2 tbsp coconut sugar
- 1 tsp ground cinnamon (for the topping)
- 0.3 tsp fine sea salt (for the topping)
- 3 tbsp coconut oil (melted and cooled slightly)
- 1 tbsp pure maple syrup (for the topping)
Instructions
- 1
Preheat your oven to 180 degrees C (350 degrees F) with a rack in the centre position. Lightly grease an 8-inch square baking dish with a small amount of coconut oil.
An 8-inch dish gives a generous layer of peach filling. A 9-inch dish works too but the filling will be slightly shallower and may cook a few minutes faster.
- 2
Peel, stone and slice the peaches into roughly 1cm thick wedges. Add them to a large mixing bowl with the maple syrup, lemon juice, arrowroot powder, cinnamon, ginger and pinch of sea salt. Toss gently until every slice is coated, then tip the mixture into the prepared baking dish and spread into an even layer.
The lemon juice brightens the peach flavour and prevents any browning while you prepare the topping. Do not skip it.
- 3
In a separate medium bowl, combine the rolled oats, almond flour, chopped walnuts, coconut sugar, cinnamon and sea salt. Stir together until evenly mixed. Pour in the melted coconut oil and maple syrup, then use a fork or your fingertips to toss and press until the mixture clumps together into a rough, crumbly texture with some larger pieces.
Slightly larger clumps in the topping bake up as satisfying crunchy chunks. Do not overmix into a fine, sandy texture.
- 4
Scatter the crumble topping evenly over the peach filling, covering the fruit in a loose, generous layer. Do not pack it down.
- 5
Bake uncovered for 35 to 38 minutes, until the topping is deep golden brown and the peach filling is bubbling around the edges and up through the crumble in places. If the topping browns too quickly before the fruit is bubbling, loosely tent with foil for the final 10 minutes.
The bubbling is your key cue that the filling has thickened properly. If it is not bubbling yet, give it another 3 to 4 minutes.
- 6
Remove from the oven and allow to cool for at least 10 minutes before serving. This resting time lets the filling thicken further so it does not pour out when spooned into bowls.
Serve warm with plain Greek yogurt, coconut yogurt or a small scoop of frozen banana nice cream for a fully dairy-free option.

Pro Tips
- ✓
Choose peaches that yield slightly to gentle pressure for the best flavour and natural sweetness. Rock-hard peaches will not soften and sweeten in the same way during baking.
- ✓
To peel peaches quickly, score a small X on the base, blanch in boiling water for 30 seconds, then transfer straight to iced water. The skins slip off effortlessly.
- ✓
Certified gluten free oats are essential if you are cooking for anyone with coeliac disease. Standard oats are often contaminated with wheat during processing.
- ✓
For a richer, slightly more buttery flavour in the topping, substitute one tablespoon of the coconut oil with a tablespoon of cold almond butter stirred in.
- ✓
Do not use quick-cook oats. They become mushy rather than crisp during baking. Rolled oats give the topping its signature chewy-crunchy texture.
- ✓
This crisp reheats beautifully. A few minutes in a 160 degree C oven brings the topping back to its original crispness far better than a microwave.
Frequently Asked Questions
Variations
- •
Peach and Raspberry Crisp
Replace 150g of the peaches with fresh raspberries stirred through the filling. Raspberries add a tart, bright note that cuts through the sweetness and bumps the fibre content even higher. No other changes needed.
- •
Peach and Ginger Crisp
Add one teaspoon of freshly grated ginger to the peach filling alongside the ground ginger, and stir a tablespoon of finely chopped crystallised ginger through the crumble topping. The heat of the ginger against the sweet peaches is genuinely wonderful.
- •
Spiced Peach and Cardamom Crisp
Replace the ground ginger in the filling with half a teaspoon of ground cardamom and add a small pinch of ground nutmeg. This gives the crisp a slightly more exotic, floral warmth that works especially well served with coconut yogurt.
- •
Mini Individual Peach Crisps
Divide the filling and topping evenly between six small ramekins set on a baking tray. Reduce the bake time to 25 to 28 minutes. Individual portions are great for dinner parties and look beautiful served straight from the ramekin with a spoonful of yogurt.
Substitutions
- •Coconut oil → Unsalted grass-fed butter (Use the same quantity. The butter adds a slightly richer, more traditional flavour to the topping. Note that this makes the recipe no longer dairy free.)
- •Almond flour → Sunflower seed flour or additional certified GF oats (For a nut-free version, grind sunflower seeds finely in a blender to create a seed flour and use in an equal quantity. Extra rolled oats also work but the topping will be slightly less rich.)
- •Coconut sugar → Light brown sugar or date sugar (Use the same quantity. Date sugar keeps the recipe refined-sugar-free and adds a mild caramel depth similar to coconut sugar.)
- •Maple syrup → Raw honey (Use the same quantity in both the filling and topping. Note that honey makes the recipe no longer vegan. The flavour is slightly floral and pairs beautifully with peaches.)
- •Fresh peaches → Nectarines or apricots (Nectarines can be used without peeling and have a slightly more tart flavour. Apricots are smaller, so use around 800g and halve rather than slice them. Adjust maple syrup in the filling slightly upward if your stone fruit is less ripe.)
- •Walnuts → Pecans (Pecans are slightly sweeter and softer than walnuts and work brilliantly in this topping. Use the same quantity and roughly chop them to a similar size.)
🧊 Storage
Cover the cooled crisp tightly with beeswax wrap or transfer portions to an airtight container. Store in the refrigerator for up to 4 days. To reheat, place the desired portion in an oven-safe dish and warm at 160 degrees C for 10 to 12 minutes until the topping is crisp again and the filling is heated through. Avoid microwaving if you want to preserve the topping texture, though a 60-second microwave blast is fine if you do not mind a softer crumble.
📅 Make Ahead
Assemble the unbaked crisp up to 24 hours ahead, cover and refrigerate. Bake straight from the fridge, adding 4 to 5 extra minutes to the bake time. The topping can also be made separately up to 3 days ahead and stored in an airtight container in the fridge until ready to use.
