Crock Pot Apple Crisp

This Crock Pot Apple Crisp uses canned apple pie filling topped with a buttery brown sugar oat crumble all slow cooked together. The easiest most hands-off fall dessert for just $1.28 a serving with no peeling or slicing required.

Apple crisp is one of our favorite fall desserts and making it in the slow cooker means the whole house fills with the most incredible cinnamon apple smell all afternoon without me having to do anything. We always serve it warm straight from the crockpot with a big scoop of vanilla ice cream and my kids come running to the kitchen the moment they smell it cooking.

Most slow cooker desserts trade texture for convenience. This one doesn’t, as long as you let the steam out at the end — that one step is what keeps the oat topping crumbly instead of soft.

If you love easy fall desserts like this one you will also love our Peach Dump Cake, Peach Cobbler Recipe, and Crockpot Apple Dump Cake. They are all budget-friendly, made with simple ingredients, and the kind of warm cozy desserts your family will request all fall and winter long.

Ingredients

• Apple pie filling — two standard 21 oz cans give you the perfect amount of sweet spiced apple filling. This is the shortcut that makes this recipe incredibly fast — no peeling coring or slicing required. Use your favorite brand or homemade apple pie filling
• Brown sugar — adds extra sweetness and a rich caramel depth to the oat topping. Light or dark both work — dark brown sugar gives a deeper more molasses-forward flavor
• Rolled oats — the base of the crisp topping. Old fashioned rolled oats give the best hearty crumbly texture. Do not substitute with quick oats — they absorb too much moisture and make the topping mushy
• All purpose flour — gives the topping structure and helps it hold together in satisfying crumbles
• Salted butter, melted — binds the topping together and gives it that rich buttery flavor. Salted butter is used here so no extra salt measurement is needed in the topping
• Ground cinnamon — adds warm fall spice throughout the topping. The apple pie filling already has cinnamon but adding more to the topping layers the flavor beautifully
• Salt — balances the sweetness and enhances all the other flavors in the topping

How to Cook Apple Crisp in the Crock Pot:

Step 1 – Prep the crock pot and add the filling – Spray a 5 or 6 quart crock pot with non-stick cooking spray, or drop in a slow cooker liner for zero cleanup. Spread both cans of apple pie filling evenly across the bottom. If your slow cooker is smaller than 5 quarts, cut the recipe in half — an overfilled crock cooks unevenly and the topping won’t set.

Step 2 – Combine topping ingredients – In a large mixing bowl, stir together the rolled oats, brown sugar, all purpose flour, cinnamon, and salt. Pour the melted butter over the top and stir until every bit of the oat mixture is coated and it looks like damp crumbs. Spoon it evenly over the apple pie filling and spread it to the edges — don’t stir it in.

Step 3 – Cook until the topping is set – Cover and cook on high for 2 to 2½ hours. You’re looking for three things: the filling bubbling up around the edges of the crock, the topping dry to the touch instead of glossy, and the oats around the rim turning golden brown. Slow cookers run differently, so start checking at the 2 hour mark.

Step 4 – Let the steam out for the last 30 minutes – This is the step that decides whether your topping is crisp or soggy. For the final 30 minutes, either prop the lid open about an inch with the handle of a wooden spoon, or lay a folded paper towel across the top of the crock and set the lid on top of it. Both let the condensation escape instead of dripping back down onto the oats.

Step 5 – Serve and Enjoy – Then serve warmed topped with ice cream or whipped cream and enjoy!

Tips for Success

• Use apple pie filling straight from the can. No prep required — just pour it in and spread it out. This is the shortcut that makes this one of the fastest desserts on the site
• Do not use quick oats. Old fashioned rolled oats hold their structure during the long cook time — quick oats absorb too much moisture and turn the topping mushy instead of crumbly
• Do not stir after adding the topping. Leaving the topping undisturbed lets it set into a proper crumble layer — stirring it into the filling gives you a mixed result instead of distinct apple and crumble layers
• Prop the lid in the last 30 minutes. This is the most important tip — the steam vent lets moisture escape and firms up the topping significantly for the best texture
• Serve immediately for the best texture. Apple crisp is at its very best warm straight from the slow cooker — the topping softens further the longer it sits in the residual moisture
• Try the paper towel trick. A reader named Carla left this one in the comments and it works beautifully: instead of propping the lid, lay a folded paper towel across the top of the crock and set the lid over it for the last 30 to 60 minutes. It catches the condensation before it can drip back onto the oats.
• If doubling this recipe, use a large enough slow cooker (6 quarts or more) and expect to add extra cook time — doubled batches can cook unevenly in a smaller crock, with the bottom finishing well before the top.
• Use a slow cooker liner if you have one. Apple pie filling caramelizes onto the sides of the crock and takes real scrubbing to get off. A liner means you lift it out and throw it away — worth it for a dessert you’re serving to company.

Feeding a Crowd (or Just Two)

For 10 to 12 people: double everything and use a 6 to 8 quart slow cooker. A doubled batch takes longer and cooks unevenly if the crock is crowded, so plan on 3 to 3½ hours and give it the full 30 minutes with the lid propped.

For 2 or 3 people: halve everything and use a 3 or 4 quart slow cooker. Check it at 1½ hours.

To stretch it further without buying more: serve it in smaller bowls over a scoop of vanilla ice cream instead of alongside it. The ice cream does the volume work and one batch comfortably serves eight that way — which takes it from $1.28 a serving to about $0.96 plus the ice cream.

Variations and Substitutions

• Swap apple pie filling for cherry, peach, or blueberry pie filling for a completely different flavor with the same method
• Add a handful of chopped pecans or walnuts to the oat topping for extra crunch
• Add a pinch of nutmeg or cardamom to the topping for extra warm spice
• Use gluten free oats and gluten free flour for a gluten free version
• Drizzle caramel sauce over the top right before serving for an extra indulgent fall dessert

Topping Ideas

• Vanilla Ice Cream – This is amazing with a scoop of vanilla ice cream. The cold ice cream melts into the warm apple crisp.
• Whipped Topping – Top with whipped cream for another great idea.
• Drizzle with Caramel Sauce – A warm drizzle of homemade caramel sauce over the top turns this into caramel apple crisp. It takes about 10 minutes to make and costs a fraction of a jar from the store.

Storage and Freezer Instructions

Refrigerator

• Store in an airtight container for up to 3–4 days. The oat topping will soften overnight in the fridge — that’s normal, not a mistake. To bring the crunch back, spread leftovers in an oven-safe dish and broil on low for 1 to 2 minutes, watching the whole time so the oats don’t scorch.

Freezer

• Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator, then reheat uncovered in a 325°F oven for about 20 minutes. Be aware the topping comes out softer after freezing — closer to a baked apple crumble than a crisp. If crunch matters to you, freeze the crumble topping and the pie filling separately in zip-top bags instead, then dump both into the slow cooker straight from frozen and add about 30 minutes to the cook time.

Reheating

• Microwave for 60–90 seconds for a quick serving or reheat in the oven at 325°F for a slightly crispier topping result. Always serve warm with ice cream for the best experience
