Recipe tested & approved
A quick, rustic strawberry crisp using an air fryer. Uses fresh fruit thickened with arrowroot and a crunchy crumble topping made with oats, almond flour, and honey. Slightly tweaked from the classic version with less sugar, a hint of lemon zest, and a pinch of cinnamon. Great for small desserts, meals for four, ready in under 40 minutes total. Textures contrast warm, bubbling fruit beneath a golden, crispy oat topping. Moist but crumbly, semi-sweet, balanced. Substitutions suggested for dairy-free, nut-free options. Relies on sensory cues more than strict timings for best outcome.

Strawberries—fragile, sweet, unstable under heat. Learned the hard way: too long, and it’s a mush puddle; too short, and you’re stuck with cold fruit hiding under a crispy hat. Air fryers, my latest obsession for quick desserts. Faster than an oven, crisp tops without sogginess that often plagues microwave or toaster oven. The trick? Arrowroot instead of starch—transparent, no dullness to the red berries. Honey replaces sugar in crumble—keeps it moist but with a floral scent, breaking the usual granulated monotony. Also swapped flour for almond for nuttiness and chew, but oat flour works if nuts aren’t your thing. Toppings are all about texture: clumps, crunchy bits, not a flat dusty sheet. You want cracks revealing fruit steam below. Timing is flexible; watch the bubbling, listen for crisps, smell the golden toasty scent. Leave warm if you must, but not cold. Cold kills crumble texture and turns buttery bits waxy. This dish doesn’t wait.
Ingredients
Fruits
- 240 g fresh strawberries sliced (about 1 2/3 cups)
- 40 g granulated sugar (3 tbsp)
- 6 ml lemon juice (1 1/4 tsp)
- 7 g arrowroot powder (1 1/2 tsp)
- 1/4 tsp ground cinnamon
Crumble
- 55 g quick-cooking rolled oats (1/2 cup)
- 30 g almond flour (1/4 cup) — substitute with oat flour if nut-free
- 45 g honey (3 tbsp) — use maple syrup for vegan
- 40 g coconut oil, softened
- 1 tsp lemon zest
About the ingredients
Strawberries assumed fresh; if frozen, thaw and drain excess juice before mixing or reduce lemon juice accordingly to avoid sogginess. Arrowroot powder replaces cornstarch—less cloudy, better for delicate colors and flavor. Granulated sugar lowered by 30%, balanced with lemon juice to keep brightness. Using cinnamon adds warmth and a little spice dimension, easy to omit if you prefer pure berry notes. Crumble mix swaps half flour to almond flour for richer, moister texture, and swaps out sugar for honey which caramelizes gently in air fryer heat. Coconut oil chosen for browning properties and allergy-friendly status—not as stable as butter, so watch temperatures closely. If using butter, reduce heat slightly and watch browning carefully. Lemon zest is the twist, adds brightness without acid. For nut-free diet, oat or chickpea flour subs almond flour, and maple syrup replaces honey for vegan variation. You’ll want firm but fresh ingredients; overly soft berries will turn to jam, ruining texture contrast.
Method
Fruits
- In a medium bowl, toss sliced strawberries with sugar, arrowroot, lemon juice, and cinnamon. Coat evenly; arrowroot thickens the juicy berries without clouding their bright flavor. Set aside to macerate for 10 minutes or until strawberries start releasing some juice — this signals they’re ready to soften without becoming mushy.
- Divide mixture into four 180 ml ramekins — about 3/4 cup each. Don’t overcrowd; air fryer circulation needs room. Arrange ramekins in the air fryer basket.
- Air fry at 185ºC (365ºF) for 12 minutes. You’ll hear gentle bubbling, see juices darken and thicken. If juices are still runny, add a couple more minutes until you notice slight thickening on sides.
Crumble
- While fruits cook, mix oats, almond flour, lemon zest, and cinnamon in a bowl. Melt coconut oil, whisk in honey until just combined. Pour over dry mix and stir gently until crumbly but moist—if too sticky, add more oats a teaspoon at a time.
- Remove basket carefully—ramekins will be hot. Press crumble with hands into small clumps, scatter evenly atop fruit. Don’t pack down; leave some spaces for steam to rise and maintain crunch.
- Return basket to air fryer. Cook another 11 minutes or until topping turns golden with darker brown spots and emits toasty aroma. Listen for a mild crackle from crisping oats. If still pale, add 2-minute increments.
- Pull basket out, let rest uncovered for 5-7 minutes to firm up crumble; hot steam dissipates making topping crisp instead of soggy. You’ll see bubbling juices along edges, crisp top slightly pulling away from sides.
- Serve warm or room temperature. Ideal with dollop of coconut yogurt or vanilla ice cream.
- If air fryer size limits, cook ramekins in batches or choose smaller vessels. Overfilling dense fruit mix or topping leads to uneven cooking.
- Keep an eye on crumble early on—coconut oil browns quickly; too hot air fryer risks burnt edges. Adjust temperature down 10ºC if necessary.
- Leftovers reheat in air fryer for 3-4 minutes at 160ºC to revive crisp.
Cooking tips
Step order shifted to let fruits macerate to protect texture from air fryer heat shock; fruit needs a chance to pre-release juices so they thicken better under heat instead of leaking out helplessly. Cooking in increments important; read bubbling and color changes rather than strict time. Using visual cues prevents drying or burning. Crumble must be gently pressed, not packed—allows hot air to circulate, forming uneven crunchy textures instead of a flat skin. Removing basket mid-cook doubles as cool-down pause and topping spreading step, reduces total cook time by letting you multi-task crumble prep. Resting uncovered after cooking crucial; too often skipped and crumble goes limp from trapped steam. Use felt heat when removing basket—ramekins hot and can splash juices. If air fryer basket is small, do in batches; overloading reduces hot air circulation leading to soggy centers and uneven topping. Reheating short and moderate heat avoids dry crumb or burnt edges. Replace coconut oil with good quality unsalted butter if you want a more traditional crumble fat flavor but lower temperature to avoid rapid browning. The lemon zest is subtle but keeps the crumble from feeling monotonous.
Chef's notes
- 💡 Use coconut oil soft but not melted. Liquid oil mixes weird, crumb texture breaks down. Press crumble gently so bits stay loose, steam escapes crisp clusters form, not solid crust.
- 💡 Macerate berries at least 10 minutes. Look for juice starts bubbling, fruit softens but keeps shape. Skip this—jammy mess appears, soggy base follows. Arrowroot key, clear thickening without cloudy juice.
- 💡 Test ramekin size first. Air fryer models differ big time. Overcrowd and fruit + topping cook unevenly. Smaller ramekins okay batch cook, or adjust timing to avoid underdone centers or burnt edges.
- 💡 Honey browns slower than sugar but can stick more. Use maple syrup for vegan, expect slightly stickier crumb. Crumble dries fast—watch initial color closely, reduce heat 10 degrees if it burn fast. Listen for crackles.
- 💡 Lemon zest brings brightness, avoids flat flavor. Add just before topping fruits, not in oil mix or crumble goes oily smelling. Press crumble lightly, don’t pack. Hot steam rising keeps topping crispy, avoids dense cakey feel.
Common questions
Can I use frozen strawberries?
Yes but thaw fully, drain juice well. Excess water ruins crisp texture. Reduce lemon juice to avoid sogginess. Air fryer needs dry surface to brown properly. Frozen berries always tricky.
Almond flour substitute?
Oat or chickpea flour work good for nut allergies. Texture changes, less moist richness, but acceptable. Avoid plain flour; dry texture and missing nuttiness. Maple syrup swaps honey for vegan use; expect stickier crumb.
Why does crumble get greasy sometimes?
Coconut oil too soft or melted messes clusters. Press too hard or too thick also traps oil. Adjust oats to soak excess fat, dry mix first then wet. Resting uncovered after cook helps firm topping.
Storing leftovers tips?
Cool completely then cover loosely. Fridge keeps crisp but loses some crunch over time. Reheat 3-4 mins at 160ºC in air fryer revives crisp. Avoid microwave—makes topping soggy fast. Can freeze but texture changes.
