Keto Stewed Rhubarb

Stewed rhubarb is a great low-carb recipe for those cooking fresh rhubarb for the first time. It’s a quick and easy rhubarb sauce that just requires cooking the rhubarb slices in a combination of water and your favorite sugar-free sweetener. 

The addition of a cinnamon stick is totally optional and can be left out completely or replaced with a teaspoon of either orange, lemon, or vanilla extract. Or even your choice of citrus zest. 

The taste of this sauce is slightly sweet with a little tartness.  It’s a rhubarb recipe that will take you less than 20 minutes to make from start to finish.

The key to making this dish is to cook the rhubarb slowly so that it breaks down and becomes soft. This process allows the natural tanginess of the rhubarb to come out while also intensifying the natural sweetness.

Stewed keto rhubarb makes a great topping for many desserts, including pancakes or waffles! I’ve also been known to just have a tablespoon after dinner as a quick dessert.

Optional Add-in

It’s a well-known fact that the flavors of rhubarb and strawberries go together beautifully. If you want a rhubarb-strawberry sauce, just add 1/2 cup of sliced strawberries while cooking the rhubarb. 

A little strawberry adds tons of flavor, and by adding strawberries you create a sugar-free strawberry rhubarb jam!  That you can then enjoy your favorite low carb bread.

The great news is that it can be stored in the fridge in a mason jar for quick access.

I love that it can be easily customized by adding your favorite spices and flavorings. I added half a cinnamon stick to the pot of simmering rhubarb but you can opt to add orange or lemon peel instead.

• Fresh or frozen rhubarb sliced into 1/4-inch pieces 
• Granulated sugar substitute
• Water
• Cinnamon stick (optional)

Do You Need To Peel Rhubarb Before Stewing?

To prepare the rhubarb for stewing, trim off the top and bottom of the rhubarb and chop it into one-inch pieces. 

There is no need to peel rhubarb that is in peak season, but late in the summer rhubarb stalks can get tougher and could benefit from being peeled before stewing.

How To Make Keto Stewed Rhubarb Sauce

Making this rhubarb compote is super easy. To make this recipe, wash the rhubarb stalks and slice them into 1/4 inch pieces. Remember to discard any rhubarb leaves and not use the tough end of the rhubarb.

Then in a small pot, combine the sugar substitute, water, and 1/2 a cinnamon stick or your choice of flavorings and bring to a low boil over medium heat.

Be sure to stir occasionally while it simmers to ensure all the sugar has dissolved.

Then add the rhubarb slices and reduce the heat to a low to simmer and cook until rhubarb is tender but still crisp, for about 15 minutes, or until the rhubarb pieces start to break down and the sauce begins to thicken. 

Once cooled, store in a covered container in the fridge for up to a week or up to two months in the freezer.

Next, remove the cinnamon stick before allowing it to cool down completely. Then add the rhubarb compote to an airtight container once it has cooled for about one week in the refrigerator.

You can also freeze this sauce either in a freezer bag or an airtight container for up to two months.

Stewing Rhubarb Tips

This easy 3-ingredient low-carb recipe is a great way to use up any beautiful stalks of rhubarb.

It’s important to keep in mind that the cooking time will vary between the type of rhubarb you are using and how ripe it is.

The cooking time is simply a guide.

Keep in mind that the longer you cook the rhubarb, the more the rhubarb will break down and make for a thicker sauce.

If you want to keep more of the rhubarb pieces intact, you will need to stop cooking as soon as it’s fork-tender.

Depending on the ripeness and type of rhubarb you use will determine how sweet it is naturally.

Once the sauce is cooked, you can taste and adjust the sweetener by adding a teaspoon at a time if your rhubarb is not as sweet as you prefer.

Can I Stew Frozen Rhubarb

Yes, you can make this rhubarb compote with frozen rhubarb. The best part is that you won’t even need to thaw the rhubarb before cooking. 

You can make this rhubarb sauce with frozen slices of rhubarb. The rhubarb would have to be frozen in slices.

Just keep in mind, that you will just need to cook a little longer to give time for the rhubarb to thaw completely and cook down.

Best Sugar-Substitutes For Sugar-Free Stewed Rhubarb

To make this delicious rhubarb sauce, you can use your sweetener of choice, but it needs to be sugar-free in order for this to be considered keto-friendly. 

My top pick is a monk-fruit erythritol blend for best results. My personal favorite is Lakanto’s brand. 

I also use Swerve, an erythritol sugar substitute, with great success.

You could also use stevia and erythritol-based brand like Pyure for most of my baked goods. 

However, if using Pyure, you will want to use half the amount called for in this recipe since it’s a much sweeter choice. 

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda or a generic brand of the same.

I know not everyone would agree with me here, and I respect that, but in my book, it’s still better than regular sugar.
