Ingredients for Apple Crisp
Apple Crisp Filling
- 6 cups Honeycrisp apples (about 6 medium), peeled and sliced into ½″ wedges
- 2 tsp fresh lemon juice
- 1 ½ tsp vanilla extract
- ¼ cup (50g) granulated sugar
- ¼ cup (50g) light brown sugar, packed
- 2 tbsp cornstarch
- 1 tsp ground cinnamon
- ¼ tsp ground ginger
- ⅛ tsp ground nutmeg
- ⅛ tsp ground cloves
Apple Crisp Topping
- 2 cups (200g) old-fashioned rolled oats (certified gluten-free if needed)
- 1 cup (100g) almond flour

Step-by-Step: How to Make Apple Crisp in the Slow Cooker
If you like a crunchy topping (same!), the key is cooking the apples first, then adding the oat crumble halfway through.
Step 1: Prep the Apples
Peel and slice about 6 medium apples into ½-inch wedges. In a bowl, toss with lemon juice, vanilla, granulated sugar, brown sugar, cornstarch, cinnamon, ginger, nutmeg, and cloves until evenly coated.
Step 2: Start the Filling
Grease the slow cooker insert. Add the spiced apples and spread into an even layer.
Cook: HIGH 1½–2 hours (or LOW ~3 hours) until the apples begin to soften and release their juices.
Why this works: Letting the apples cook first concentrates their juices and keeps the crisp from getting soggy later.
Step 3: Mix the Topping (while apples cook)
In a separate bowl, combine rolled oats, almond flour, brown sugar, salt, and cinnamon. Cut in the cold cubed butter with a pastry cutter or fork until the mixture looks sandy/pebbly and clumps when pressed.
Step 4: Add the Topping
Lift the lid and sprinkle the oat mixture evenly over the partially cooked apples. Don’t stir—just cover the fruit.
Step 5: Keep the Topping Crisp (steam hack)
Place a thick paper towel or clean kitchen towel directly under the lid (between the lid and the crock) to catch condensation. Make sure the towel edges don’t touch any hot surfaces.
Cook again: HIGH ~1½ hours (or LOW ~3 hours) until the apples are tender and the topping is set and golden.
Crisp Topping Tip: That towel absorbs steam so droplets don’t drip back onto the crumble—hello, crunchy topping.
Step 6: Serve Warm
Scoop your apple crisp into bowls and serve as-is or with vanilla ice cream, whipped cream, or caramel.
Optional extra-crisp finish: If you want even more color, briefly spoon the topping onto a sheet pan and broil 1–2 minutes, then return it to the slow cooker. (Only if you’re feeling extra!)

Notes
- Timing Tip: Adding the topping halfway ensures it stays crisp instead of soggy.
- Crisp Topping Hack: Place a thick paper towel (or clean kitchen towel) directly under the slow cooker lid while the topping cooks. This absorbs excess steam so the oat topping stays crunchy.

FAQ: Apple Crisp in the Slow Cooker
Can I make apple crisp without oats?
Yes! While oats give apple crisp its signature texture, you can substitute crushed graham crackers, granola, or even chopped nuts for crunch. It changes the texture slightly, but still tastes amazing.
What apples work best for apple crisp?
Honeycrisp are my go-to for their sweet-tart flavor and firm texture, but Granny Smith, Pink Lady, Fuji, or Cosmic Crisp also hold up well. Mixing two varieties gives the best balance of flavor.
Can I prep this apple crisp ahead of time?
Absolutely. You can peel and slice the apples a day in advance (toss them with lemon juice to prevent browning) and store them in the fridge. The topping can be mixed ahead and chilled separately. Assemble and cook when you’re ready.
How do I keep the topping crunchy in the slow cooker?
The trick is to cook the apples first, then add the topping halfway through. For extra crispiness, place a thick paper towel under the lid to absorb steam. You can also finish the topping under the broiler for a couple of minutes if you want more crunch.
Can I freeze apple crisp?
Yes! Let it cool completely, then store portions in airtight containers or freezer bags for up to 3 months. Reheat in the oven for the best texture.
Storage & Leftovers
