Step-by-Step Instructions

This easy recipe is all about layering, setting, and letting your crockpot apple crisp cook itself while you go about your day.

Step 1: Prep the apples
Peel, core, and slice your apples. Toss them in a bowl with lemon juice, a bit of brown sugar, cinnamon, and vanilla extract. This coats them with flavor and helps them soften evenly while cooking.

Step 2: Layer into the crockpot
Lightly grease your slow cooker insert. Add the apple mixture to the bottom and spread evenly.

Step 3: Make the topping
In a separate bowl, combine oats, flour, brown sugar, cinnamon, nutmeg (if using), and a pinch of salt. Cut in cold butter using your fingers or a pastry cutter until the mixture becomes crumbly and coarse.

Step 4: Add topping over apples
Sprinkle the topping evenly over the apple layer in the slow cooker. Do not stir. You want the topping to sit right on top so it can crisp up while cooking.

Step 5: Slow cook uncovered
Cook on high for 2 to 2½ hours or on low for 3½ to 4 hours. For a crispier top, prop the lid open slightly with a wooden spoon during the last 30–45 minutes to release steam.

Step 6: Serve warm
Scoop into bowls and serve warm on its own or with vanilla ice cream. The contrast of cold and hot is unbeatable.

This crisp comes together just like my simple Banana Oatmeal Cookies and is every bit as easy as the Apple Crumble Cheesecake you might already love.

Tips & Substitutions

Want to tweak or perfect your crockpot apple crisp? Here are some helpful swaps and success tips:

• Apple choice matters: A blend of tart (like Granny Smith) and sweet (like Fuji or Honeycrisp) adds depth
• For a gluten-free version, use certified gluten-free oats and a 1:1 gluten-free flour
• Butter substitute: Use vegan butter or coconut oil for a dairy-free option
• Spice it up: Add a dash of clove or allspice for extra fall flavor
• Avoid sogginess: Prop the lid during the last part of cooking to allow steam to escape
• Oats tip: Stick with old-fashioned oats—they hold texture better than quick oats

These easy tricks also work beautifully with my Carrot Cake Cinnamon Rolls and are worth trying in other fruit crisp recipes.

Storage & Reheating

Store any leftover crockpot apple crisp in an airtight container in the refrigerator for up to 4 days. To keep the topping crisp, reheat portions in the oven or toaster oven at 350°F for 10–15 minutes. If you’re in a rush, the microwave works too—just know the topping may soften.

To freeze, place cooled portions in freezer-safe containers. Reheat directly from frozen in the oven for best texture.

FAQs About Crockpot Apple Crisp

What is the difference between apple crisp and apple crumble?
Both feature baked apples with a topping, but apple crisp typically includes oats, giving it a crunchy texture. Apple crumble usually uses a streusel-like topping made only of flour, sugar, and butter—no oats.

Can I make crockpot apple crisp ahead of time?
Yes. You can assemble it in the crockpot insert the night before and refrigerate. When ready to cook, let it sit at room temperature for 30 minutes, then turn on your slow cooker.

How do I prevent the topping from becoming soggy in crockpot apple crisp?
The key is to leave the lid cracked open during the final 30–45 minutes of cooking to let steam escape. This helps the topping crisp up instead of getting soft from trapped moisture.

What are the best apples for crockpot apple crisp?
Firm, tart varieties like Granny Smith, Honeycrisp, or Braeburn hold up best during long cooking and offer a great balance of sweetness and texture.

Can I use instant oats instead of old-fashioned oats in crockpot apple crisp?
It’s not recommended. Instant oats break down too quickly and won’t give you that signature crisp topping. Stick with old-fashioned oats for best results.

How long can I keep crockpot apple crisp leftovers?
Stored properly in the fridge, leftovers stay fresh for up to 4 days. You can also freeze portions for longer storage and reheat as needed.
