A Unique Combination Rhubarb Salad With Toasted Cashews

Each year we have an abundance of rhubarb from our one plant that gives us four crops throughout the summer months.

This season our new recipe is a colourful summer fresh rhubarb salad.

We’ve loaded this amazing keto salad with fresh fennel and other crisp vegetables topped with toasted cashews and tossed in a sweet apple cider vinaigrette.


YES, this salad is low-carb and perfect for the keto diet as rhubarb is low in carbs.

High-Fibre Keto Salad With Rhubarb

Healthy salads are always part of our menu plan during the summer months especially since produce is easily accessible.

Most importantly we try to add lots of fibre to our diet to keep the system moving all of which rhubarb has to offer.

Summer salads in our kitchen always include a protein so pairing this rhubarb salad with BBQ’d Atlantic salmon was a hit.

Mrs. CBB added sugar-free maple syrup instead to keep the rhubarb salad and salmon dish keto-friendly.

Growing rhubarb has been an experience for us since Mrs.CBB had never tried it before. I know shocking right?

From a financial standpoint, I couldn’t believe how expensive it was to buy at the supermarket.

Grocery Store Rhubarb Costs

Buying rhubarb out of season or even in-season will hit your pocketbook hard but worth it if you don’t have a green thumb.

The rhubarb in-season was priced at $4.99/lb at the time of writing this blog post.

If you enjoy rhubarb all you need is one rhubarb plant and it will give you many harvests throughout the season.

Our rhubarb season in Ontario starts in May and we finish harvesting into the last week of August.

Depending on where you live even in Ontario this may differ but this is what happens at our house.

Rhubarb 101

  • Is rhubarb fruit? or Is rhubarb a vegetable?
  • What does rhubarb taste like?

Everyone wants to know so I’m going to set the record straight.

Rhubarb is a vegetable however it’s used mainly as a fruit for its tart flavour.

The crunch of rhubarb is similar to that of celery but it tastes like a very tart green apple.

The rhubarb stalks (petioles) are long and tender and can be a bright red or pale green colour.

Most people enjoy rhubarb dipped in sugar or paired with other fruits.

Other favourite ways to eat rhubarb is topped with whipped cream, custard, or baked into a pie or square.

Heck, you can even make Keto rhubarb smoothie too!

Rhubarb offers lots of vitamins and minerals.

Just today not only did we make this gorgeous rhubarb salad but we also made a large pan of strawberry rhubarb custard bars.

In the past, we’ve used our rhubarb also to make rhubarb jam and topped ice-cream with it.

Planting Suitability For Rhubarb

Where to plant rhubarb?

I’m no pro BUT judging by the size of our rhubarb plant and where it is planted I’d say plant it right next to the downspout of your home.

When it rains it will make sure your rhubarb plant gets plenty of water. Our back garden also gets lots of sunshine during the day.

This has served our rhubarb plant well over the past 20 years of its life and now gives us more rhubarb than we know what to do with.

Most years we give it away to friends and family who happily come and pick some up.

Rhubarb is full of nutrients and traditional Chinese medicine was used as a laxative due to the high fiber content.

Rhubarb is low in calories and carbs and has plenty of vitamin K, C, Calcium, and potassium.

The only part of the plant you want to avoid eating is the leaves as they are highly toxic to humans.

Rhubarb leaves contain poisonous substances, including oxalic acid, which is a nephrotoxic and corrosive acid that is present in many plants.

Humans have been poisoned after ingesting the leaves, a particular problem during World War I when the leaves were mistakenly recommended as a food source in Britain.

Summer Fresh Keto Rhubarb Salad with Toasted Cashews
Recipe Type: Salad

Serves: 4
You’ll love this new keto salad recipe that we created with rhubarb because it’s unique and perfect as a side dish for your summer protein off the grill.
  • 1 red pepper
  • 1 yellow pepper
  • 2 spring onions
  • 1 stalk of red rhubarb
  • half bulb of fennel
  • fennel greens
  • 1 cup toasted cashews
  • 1/4 cup avocado oil
  • 1/3 cup apple cider vinegar
  • 1/3 cup of honey, maple syrup or sugar-free syrup
  • 1 teaspoon pink Himalayan salt
  • 1 teaspoon fresh ground black pepper
  1. In a jar start by mixing your salad dressing together. If you don’t want the sweet salad dressing then eliminate the honey or syrup and stick with the oil, apple cider vinegar, salt, and pepper. Shake the jar vigorously to combine the ingredients and set aside.
  2. On a cutting board start by cleaning your red and yellow peppers and then slicing them julienne style to keep all of the vegetable uniform. Continue with the fennel and spring onion the same way.
  3. Add as much or little of the fennel greens to your salad and mix it all up. About 30 minutes before serving your salad add the dressing to the top and mix it in with a spoon.
  4. Sprinkle with toasted cashews and serve.


If you’d like to jazz up this rhubarb salad you could add some cooked chickpeas or even other summer vegetables that are in your crisper.

What I love about this salad is that we are using rhubarb rather than enjoying it in a sweet baked dish.

Sometimes it’s nice to think outside the box when you are in the kitchen because you never know what you might create.
