Strawberries and rhubarb are the perfect match in this keto crumble. This Strawberry & Rhubarb Crumble was inspired by this delicious Rhubarb Crisp by Carolyn Ketchum, the very talented writer and photographer at All Day I Dream About Food.

What really makes this crumble special are the macadamia nuts which are not only delicious but also high in heart-healthy monounsaturated fats (you can learn more about fats in my guide here). I don't always have fresh strawberries and rhubarb, so I either use frozen or preserved fruits (recipe for Home-made Strawberry & Rhubarb Jam is here).

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

We LOVE this recipe so much! We've been experimenting with using the crumble as a chocolate chip cookie mix. Super tasty--like an oatmeal chocolate chip cookie!

Thank you Laura!

I was so hopeful. But as I can't use erythritol, it's again a bust. I was even going to look at your app, but I
Guess I won't now. 😞

That's fine 😊 There are other sweetener options you can use instead: Complete Guide To Sweeteners on a Low-Carb Ketogenic Diet

This was marvellous! Especially the crumble. I had a bit too much, so I had it in the morning as a crunchy cereal, with some coconut milk. Absolutely delicious. Thank you for this recipe!

Thank you Tom! Glad you liked it! 😊

How important is the combination of protein powder, egg whites, and coconutoil/butter? Could that all be substituted for 2 whole eggs well beaten?

Reply

Hi Erik, I only use egg whites and protein powder because it gives it a really crispy texture. I haven't tried other combinations with whole eggs so I'm not sure how it works (may be a bit too moist / rich?)

This is one of the best recipes I've tried. I can't believe how good it tastes just like the crumble my mother used to make when I was a kid. Thank you so much!

Thank you Mellissa!! I love making low-carb crumbles. I made another one with mixed berries and cream cheese in between the layers. I will have to post this recipe at some point too! 😊

This looks delicious! I’ve been looking for a low carb recipes, I must add this to my list.

Thank you Kim! 😊

How delicious is this crumble! Love how good for you the recipe is too in comparison to other crumbles, I definitely need to try out the recipe!

Thank you Thalia! Let me know how it turned out 😊

Ohhh I love crispy pies and crumbles but haven't had any since going LCHF which is more than a year ago. I don't crave sweets apart from dark chocolate but I may give this one a try 😊 Do you think it would work with just stevia or would it be too bitter? I don't have any erythritol left...

Reply

I think you will still have to use another sweetener. If you use just stevia, you'll have to use a lot and it may get quite bitter... The rhubarb is sour so you'll need to use more sweetener in the fruit layer. Let me know how it turned out! 😊

I love crumble! What do you think, would the crisp work with some almond milk just like cereal... I mean without the strawberry base?

Reply

Me too! I think it would but make sure you don't leave it in the milk for too long or you will lose the crispiness.

This looks so yummy! I may add some cream cheese filling in the middle 😉

Reply

Thank you Mary! Yes, you can definitely use cream cheese 😊
