This Strawberry Rhubarb Sauce is simple to make, and there’s no refined sugar added! Instead, you can use either maple syrup or honey which both make for an incredible flavor pairing with this dynamite duo. The sweetness of the strawberries tempers the tangy nature of rhubarb so you don’t need quite as much sweetener either. This sauce keeps well for days in the fridge, and it’s perfect over my Homemade Coconut Ice Cream. Or try it with your favorite creamy yogurt topped with my Maple Cinnamon Granola.
Have you ever eaten raw rhubarb? Well… I wouldn’t recommend taking a very big bite that’s for sure! My Grandpa used to think it was so funny to initiate each of his grandkids into rhubarb by feeding it to us raw. It’s incredibly sour, and he laughed so hard at our puckered-up faces that he’d pretty much fall to his knees with mirth!
I think he’d love to know that I’m still eating it raw all these years later, albeit in very small bites! But raw rhubarb is sort of like biting into a lemon, so that’s why it’s the best in recipes like this sauce.
And once you’ve made this, you definitely need to head over to make my Strawberry Rhubarb Crisp too. This time of year rhubarb is plentiful, so if you’ve never tried it before, I hope this super tasty recipe will inspire you!
Ingredients & Substitutions
- Rhubarb – can usually be found at a regular grocery store during the spring to early summer months. And you can definitely find it at your local farmer’s market or maybe you have a neighbor that would be happy to get rid of some! You can sometimes find rhubarb plants at a farmers market and you could add this to your flower beds. It pretty much takes care of itself and will reward you with loads of rhubarb.
- Strawberries – I use frozen berries here because that’s all I have when rhubarb is most plentiful. But you can use fresh as well, although it may be less saucy if you use store-bought fresh strawberries because they don’t have much juice.
- Honey or maple syrup – either sweetener is good here, but I especially love honey because the flavor combo is so good with the strawberries and rhubarb.
- Tapioca starch – or cornstarch both work here to thicken up the sauce.
- Orange zest – or lemon zest adds the perfect bright note that compliments this flavor combo. You can also add freshly squeezed orange juice to enhance the flavor, or 1-2 tbsp fresh lemon juice.
Now let’s make this recipe step by step
Step 1: Trim your rhubarb stems by cutting off the tough stem ends and removing the leaves.
Step 2: Slice the rhubarb into 1/4-1/2 inch pieces. Zest the orange and measure out the rest of the ingredients.
You can slice them even larger if you’d like for more texture you just need to cook it for a few minutes longer.
Step 3: Start stirring together the tapioca starch together with water until smooth with no lumps remaining. Then add the remaining ingredients, (except the optional orange juice) to the pan and stir together.
Step 4: Simmer for a few minutes until the rhubarb is tender and beginning to fall apart, stirring occasionally. When the sauce has simmered and thickened, remove it from the heat and add the optional orange juice.
Ways to serve this
- Homemade Coconut Ice Cream or Best Vanilla Ice Cream
- with Greek yogurt or coconut yogurt and Maple Cinnamon Granola or Homemade Granola
- As a topping for my Overnight Oats or my Creamy Coconut Chia Pudding
- Over Banana Pancakes
- This sauce is also perfect for your favorite pancake recipe or waffles.
- It also pairs well with any moist vanilla pound cake. My Almond Flour Flag Cake is perfect here, just omit the frosting and berries and serve with this strawberry rhubarb sauce. From there either my Vanilla Ice Cream or Whipped Cream work perfectly as a topping.
With cornstarch or tapioca starch. If your sauce is too thin, mix together some cornstarch with water until smooth and add it slowly to the bubbling sauce until it’s as thick as you’d like. Keep in mind it will thicken up significantly when refrigerated.
Strawberry rhubarb sauce will last 1 week covered in the refrigerator or 1 month frozen.
- To store – place the leftovers into an airtight sealed container and refrigerate for up to 1 week. I like to pour mine into quart mason jars because they don’t take up much space in the fridge.
- Make ahead – this sauce keeps well for 1 week, so it’s the perfect make-ahead recipe for any way you want to serve it.
- Reheat – place the amount you want to reheat in an appropriately sized pan and heat stirring constantly over medium heat until warmed or hot.
- To freeze – place the leftovers into an airtight container that can go in the freezer and freeze for up to 1 month. Defrost overnight in the fridge before using. If you use a Ziplock bag, place the bag in a dish to catch any leaks! If the sauce has separated, you can reheat it to bring it back together.
Tips & Tricks
- Try the optional orange juice addition in the recipe below. Orange really pairs well with strawberry and rhubarb.
- You can make this with fresh strawberries, but I prefer to use frozen unless I have a lot of fresh berries to use up. Frozen strawberries are perfect for sauce and overall they’re much more economical.
- Try using honey in place of the maple syrup. Honey is a wonderful flavor pairing for this sauce as well.
- Be sure to mix the tapioca (or cornstarch) together well with the maple syrup until no lumps remain. This is the easiest way to incorporate the starch. If you use honey, mix the starch together with water or the optional orange juice. It’s a bit difficult to mix the starch together with honey because it’s much thicker than the maple syrup.
- You can also use can sugar to taste or even agave nectar in this recipe. Start with 1/2 cup sugar, then add more to taste if needed.
