Today I’m updating the photos for this Slow Cooker Blueberry Crisp that’s perfect to make as a treat for a special occasion! This recipe has been on the blog for a few years, and the day I first tested the recipe with Kara, we loved, loved, loved the blueberry crisp.
While we were cooking my sister Pam and sister-in-law Lisa both dropped by, and they devoured it too. And the leftovers were also a hit with Kara’s kids, but it wasn’t ever super popular on the blog.
And recently I was talking to Kara about the blueberry crisp recipe and we realized some people probably didn’t make it because the original recipe was for a huge blueberry crisp that served ten people and was made in the giant Crock-Pot Casserole Crock Slow Cooker (affiliate link). (You can still find the larger recipe below this new one if you want a bigger size.)
So we worked on a smaller version of the recipe with better photos to see if we could entice you to try this recipe that’s been SUCH a hit in my family. I hope you’ll try this updated version and see if you like it as much as we did! And it uses frozen blueberries so you can make it any time of year!
What ingredients do you need?
(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)
- frozen blueberries
- rolled oats; use Gluten-Free Rolled Oats (affiliate link) if needed
- melted butter
- Coconut Oil (affiliate link)
- coarsely chopped pecans or walnuts
- blanched Almond Flour (affiliate link)
- salt
- Monkfruit Sweetener (affiliate link) or sweetener of your choice
Is Slow Cooker Blueberry Crisp Low in Carbs?
Of course blueberries have some carbs, but this recipe doesn’t have added sugar, it’s gluten-free, and a moderate survey is only about 17 net carbs.
What if you don’t have coconut oil?
You can definitely make this with all butter if you don’t have coconut oil. Or use all coconut oil if you prefer.
What kind of Monkfruit Sweetener should you use?
I’m a fan of both Golden Monkfruit Sweetener (affiliate link) and Classic Monkfruit Sweetener (affiliate link) and either will work fine for this recipe.
What slow cooker did I use?
I made this updated version of Slow Cooker Blueberry Crisp in the Crock-Pot Casserole Crock Mini (affiliate link) that holds 2.5 quarts. I chose the smaller Casserole Crock because it’s less deep than most slow cookers and it can go in the oven to brown the top. But if you don’t have that model, any oval-shaped 3 quart slow cooker or a similar size will work. (If you use a different brand of slow cooker, don’t put it in the oven unless you’re sure the manufacturer says it’s safe. I think most models are, but can’t say for sure if every slow cooker crock of oven-proof.)
How to Make Slow Cooker Blueberry Crisp:
(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)
- For the new smaller size blueberry crisp you’ll need 16 oz. frozen blueberries, about 3 1/3 cups.
- Spray the slow cooker with non-stick spray and spread out the blueberries on the bottom (no need to thaw).
- Melt the butter and coconut oil together.
- Chop the pecans or walnuts with a chef’s knife.
- Buzz the oats in a food processor to get oatmeal “crumbs.” (You can skip this step if you prefer a coarser texture.)
- Mix chopped pecans with the oatmeal crumbs; then mix in the almond meal, salt, sweetener, and melted butter/coconut oil mixture.
- Spread the crisp topping over the blueberries. Cook on HIGH for 3-4 hours, until it’s bubbling and starting to smell great.
- At that point if you’re using the Crock-Pot Casserole Crock Mini (affiliate link) or another slow cooker with an oven-proof liner you can put it in the oven to crisp the top.
- We baked it at 400F/200C for about 15-20 minutes. (Don’t broil.) The baking step is optional but it does make the top more crisp.
- Serve hot and wait for compliments! And of course this would be amazing with either whipped cream or ice cream if you want to splurge!

Slow Cooker Blueberry Crisp
This Low-Sugar and Gluten-Free Slow Cooker Blueberry Crisp will be a healthy treat and it's super easy to make in the slow cooker.
Ingredients
- 16 oz. frozen blueberries
- 1 cups rolled oats (see notes, make sure the oats are gluten-free if needed.)
- 3 T melted butter
- 2 T melted coconut oil
- 2/3 cup coarsely chopped pecans or walnuts
- 1/2 cup blanched almond flour
- 1/2 tsp. salt
- 1/4 cup Monkfruit Sweetener or sweetener of your choice
Instructions
- Spray the slow cooker crock insert with non-stick spray.
- Measure frozen blueberries, and put them in the slow cooker.
- Use a food processor or the bowl attachment of an immersion blender to buzz the rolled oats until they’re chopped fairly small but not finely ground. (Optional; you can skip this if you don't mind a coarser texture for the topping.
- Melt butter and coconut oil together and coarsely chop the nuts.
- Put the ground oats into a bowl and add the chopped nuts, blanched almond flour, salt, Monkfruit Sweetener or other sweetener, and then stir in the butter/coconut oil mixture and stir to distribute it throughout the crisp ingredients.
- Spread the crisp topping over the blueberries and cook on HIGH for 3-4 hours, or until the mixture is bubbling hot and you can smell blueberries.
- The casserole crock collects a lot of water under the lid; I usually lift the lid a few times during the cooking time and drain off the water into the sink. Do it quickly so the crock won’t cool down.
- When the blueberry crisp is cooked through, if you’re using the casserole crock or an oven-proof crock you can put it in a preheated 400F/200C oven to crisp the top. This is recommended, but optional. (Don’t use the broiler with the casserole crock.) Don't put other brands of slow cookers in the oven unless you're sure it is recommended as safe by the manufacturer.
- Serve hot, with whipped cream or ice cream if you really want to celebrate.
- Leftovers will stay good in the fridge for a day or two, although we didn’t have much left over!

South Beach Diet / Low-Carb Diet Suggestions:
Obviously a dessert made with fruit can’t be strictly sugar-free, but this Slow Cooker Blueberry Crisp has only the natural sugar from the blueberries and a small amount of no-calorie Monkfruit Sweetener. The recipe also has healthy ingredients like oats, nuts, and coconut oil, and blueberries are a Superfood, so I consider this a healthy treat even though it has more carbs than many of my recipes. It’s probably phase three for the original South Beach Diet.

14 Comments on “Slow Cooker Blueberry Crisp”
We have enjoyed this recipe for years. Because of the low sugar content, we occasionally eat this for breakfast topped with yogurt!
That sounds good to me! I’m so glad you are enjoying it; thanks for taking time to let me know.
Hello Kalyn
I was wondering if one could use elderberries instead of blueberries for the crisp recipe.
I have used elderberries in pies but not in this type of dessert.
You thoughts please.
How I wish I could help, but I’ve never cooked with elderberries (or even tasted them). If you do try it, I would love to hear how it works.
Maybe try googling “substituting elderberries for blueberries” and see if anyone has written about it.
Made this dessert with fresh blueberries. The recipe was easy to follow and it tasted great! Thank Kalyn for sharing it. Will definitely make again and again.
So glad you liked it. I will have to try next time I get some fresh blueberries!
Any idea on how fresh blueberries would do in this recipe?
I haven't tried it with fresh blueberries, but I'm guessing they will work, especially since I don't thaw the blueberries when I use the frozen one. I'd watch to see if it gets done a bit sooner. Please share how this works if you try it!
How long would you bake this if you didn't want to use a slow cooker and at what degree?
My recipe for Low-Sugar and Gluten-Free Cranberry Apple Crisp bakes at 400F for 35-40 minutes, so you could use that as a guide. But this starts with frozen blueberries, so I'm not sure how that would change the cooking time. If you try it, I'd love to hear what works.
I would heat the blueberries in the oven until hot and
then add the topping and continue baking as above.
Yes, that might be a good plan!
Perfect timing! I'm in need of a great dessert for a party this weekend.
Glad you like it Lydia! This is a splurge for me but I can't say enough about how delicious it was.
