How to Dry Apples in Canada (Dehydrator and Oven Methods)

Dried apples are the gateway dehydrator project. Easy, forgiving, uses fall surplus or windfall apples, and produces a snack that’s dramatically better than commercial dried apples (which are often sulfite-treated and tooth-achingly sweet).

This guide covers the standard dehydrator and oven methods. The temperature range (55-65°C) and the lemon-water dip are the two critical details.

Pick your apples

Firmest hold their shape (best for snacking)

• Honeycrisp — high sugar, holds shape, candy-sweet dried
• Empire — firm, balanced flavour
• Cortland — pale white flesh, less likely to brown, holds shape well
• Gala — sweet, dries to a deep golden colour
• Fuji — very sweet, dense
• Ambrosia — sweet, mild, kid-friendly

Softer (still good)

• McIntosh — the Canadian classic; turns out softer but flavourful
• Spartan — BC’s McIntosh equivalent

Tart and structured

• Granny Smith — holds shape, tart-sweet when dried
• Northern Spy — heritage Canadian, dense, holds shape
• Russet — fall classic; complex flavour
• Crabapples — small, very tart; dries into tiny intense pieces

Avoid for drying

• Very ripe / mushy apples — fall apart during slicing
• Heavily bruised apples — discard or trim
• Apples that have been refrigerated for months — flavour fades; dried result is bland

You need about 1.5 kg of apples for a typical 5-tray dehydrator load (about 30-40 rings depending on apple size).

What you need

• 1.5 kg fresh apples
• 60 mL bottled lemon juice (¼ cup) + 1 litre water for the dip
• OR: ¼ tsp ascorbic acid powder + 1 litre water (alternative anti-browning treatment)
• Apple peeler-corer-slicer (optional; speeds prep dramatically — ~$30 at Canadian Tire)
• OR: paring knife + apple corer
• Mandoline for uniform slices (optional)
• Dehydrator with trays at 55-65°C — see best dehydrator in Canada
• OR: oven at lowest setting (typically 65-90°C / 150-200°F) + wooden spoon to prop the door
• Baking sheets with parchment (if using oven)
• Glass jars for storage — Bernardin 500 mL or 1 L work
• Optional: vacuum-seal bags for longer storage

Method (dehydrator — preferred)

Step 1: Prep apples

1. Wash apples under cool water (especially if leaving skins on).
2. Peel if desired (skip for skin-on).
3. Core with an apple corer.
4. Slice 4-6 mm thick. Thinner slices (3 mm) dry to crisp chips; thicker (8 mm) dry to chewy rings.
   • Rings (slice horizontally through cored apple): photogenic; classic look
   • Wedges (cut into 8-12 wedges): faster prep; chunkier result
   • Chunks (1 cm cubes): for granola or baking; even faster prep

A peeler-corer-slicer machine ($30 at Canadian Tire, Amazon.ca) does all three steps in 30 seconds per apple — invaluable for batches of 10+ apples.

Step 2: Lemon-water dip

1. Combine 60 mL bottled lemon juice + 1 litre cold water in a large bowl.
2. Drop apple slices into the lemon-water as you cut them.
3. Let soak 3-5 minutes before moving to dehydrator trays.
4. Drain in a colander.
5. Pat lightly dry with clean tea towels.

Step 3: Arrange on trays

1. Spread slices in a single layer on dehydrator trays. Don’t overlap.
2. Optional: sprinkle very lightly with cinnamon for cinnamon-apple chips.

Step 4: Dehydrate

1. Set dehydrator to 55-60°C (130-140°F).
2. Dry 6-12 hours depending on:
   • Slice thickness (thinner = faster)
   • Apple variety (firmer = faster)
   • Ambient humidity
3. Check at 6 hours, then every 2 hours after.

Step 5: Test for doneness

Apples are properly dried when:

• Leathery and pliable — bends but doesn’t snap
• No moisture when squeezed
• Slightly tacky to the touch is okay; wet is not

For crispier chips, dry longer (10-14 hours) until brittle. Both leathery and brittle are safe; preference matters.

Step 6: Cool and condition

1. Let apples cool 30 minutes on trays.
2. “Condition” in a sealed jar for 1 week: pack into glass jar, seal, shake daily. Watch for any condensation on the jar walls — that means apples weren’t dry enough. Return to dehydrator for another 1-2 hours if you see moisture.
3. After 1 week with no condensation, apples are ready for long storage.

Method (oven)

Same principle, slightly less consistent:

1. Prep apples as above.
2. Lemon-water dip.
3. Arrange on parchment-lined baking sheets in a single layer.
4. Set oven to lowest temperature (typically 65-90°C / 150-200°F).
5. Prop oven door open 5 cm with a wooden spoon.
6. Dry 4-8 hours, rotating sheets every 2 hours.
7. Test for doneness as above.

Storage

• Glass jar, tight lid, cool dark place: 6 months at peak quality
• Vacuum-sealed bags: 12-18 months
• Frozen, airtight: 18-24 months
• Once opened: reseal between uses; humidity is the enemy

Variations

Cinnamon apple chips

Sprinkle slices with cinnamon (and optional brown sugar) before drying. Classic.

Apple-spice chips

Sprinkle with apple-pie spice (cinnamon + nutmeg + clove + allspice) before drying. Holiday flavour.

Chocolate-dipped dried apple

After drying, dip ½ of each slice in melted chocolate. Let set. Gourmet snack.

Honey-glazed apple

Brush slices with diluted honey (1 tbsp honey + 2 tbsp water) before drying. Sticky-sweet result.

Caramel-dipped apple

Same idea as chocolate but with caramel. Best for crispy-dried apples, not pliable.

Apple-cinnamon granola mix

Chop dried apples into pieces; mix with oats, nuts, dried cranberries. Pack into jars.

Apple chip cinnamon-sugar coating

Toss freshly-dried apple chips (still slightly warm) with cinnamon-sugar. Sweet snack.

Mixed dried fruit medley

Dehydrate apples alongside pears, peaches, or apricots. Pack a mix into jars.

How to use dried apples

• Snacking — straight from the jar
• Lunchbox — kids’ favourite
• Granola — chopped into homemade granola
• Trail mix — with nuts and chocolate
• Hot apple cider — drop dried apples in hot apple cider; they rehydrate and add flavour
• Tea — add to herbal tea for fruit notes
• Oatmeal — chopped on top of oatmeal as it cooks
• Baking — substitute for raisins in muffins, scones, cookies
• Stuffing — chopped into pork-loin stuffing
• Pork pairing — alongside pork chops or pork tenderloin
• Cheese plate — chewy apple slices with aged cheddar
• Rehydrated for pie filling — soak in hot water 20 minutes; use in pies or crisps

Common problems

• Apples turned brown. Skipped or under-did the lemon-water dip. Brown apples are safe; just less attractive.
• Apples are tough/leathery (when you wanted crisp). Drying time too short. Continue 2-4 hours longer.
• Apples are brittle (when you wanted leathery). Drying time too long. Still safe; eat as chips.
• Mould in jar after weeks. Wasn’t dried thoroughly. Condition before sealing; discard mouldy.
• Apple chips too sweet. Sweet variety + drying concentrates sugar. Use tarter apples (Granny Smith, Northern Spy) or mix varieties.
• Apples stuck to dehydrator trays. Spray trays lightly with cooking spray before drying, or use mesh inserts.
• Apples slumped or shrank dramatically. Normal; apples lose 80% of their water content. A 1.5 kg batch yields about 300 g dried.

Yield expectations

• 1.5 kg fresh apples → 300-400 g dried apples (about 80% water loss)
• A full Cosori 6-tray dehydrator → ~500 g dried apples per session
• A typical Canadian household with a fall apple haul → 2-3 sessions per fall = 1-1.5 kg dried apples = enough for snacks and baking all year

Why home-dried apples are worth making

• Uses windfall and surplus — overripe apples or bushels from a U-pick
• Better than commercial — no sulfites, no preservatives, exactly your sweetness preference
• Cheap snack — $0.50 of apples becomes $5 of equivalent commercial dried apples
• Long shelf life — 6-12 months
• Travel-friendly — backpacking, hiking, lunchbox
• Kid-friendly — natural alternative to fruit roll-ups and gummy snacks
• Gift-friendly — Mason jars of dried apple chips with handwritten labels

When to dry apples

• September-October: peak fall apple season in Canada; freshest apples available
• Year-round: use Ontario or BC storage apples (Cortland, Empire, Honeycrisp keep for months in cool storage); supermarket apples work too

A typical Canadian apple-dehydrating session is a Saturday afternoon in October after a U-pick haul.
