This homemade blueberry sauce is here to replace sugar-laden blueberry jams, jellies, and fruit preserves with an easy blueberry compote made without refined sugar or cornstarch.

Adapted from Lindsey’s Easy Homemade Blueberry Sauce recipe over at Pinch of Yum, this healthy blueberry sauce is the perfect thick, full-bodied, and flavorful sauce to spoon over all sorts of things.

I love using it to sweeten oatmeal, pancakes, unsweetened yogurt, cottage cheese, and smoothies.

I took Lindsey’s advice and only cooked half of the blueberries (leaving the other to stir in at the end).

This trick results in a blueberry sauce with pleasant contrasting textures – perfectly sweetened mashed blueberries cooked down into a soft syrup mixed with bursts of fresh, firm blueberries in every bite.

Rather than using refined sugar, this healthy blueberry sauce is sweetened with only a tablespoon of maple syrup.

The naturally sweet blueberry flavor is emphasized by adding cinnamon, lemon juice, vanilla extract, and a pinch of salt. To thicken the sauce, cornstarch is replaced with arrowroot powder.

Needless to say, you should probably make a double batch because you’re going to want to put this sauce on everything.

Ingredient Notes

Here is a brief overview of the ingredients you’ll need to make this blueberry sauce recipe:

  • Blueberries – These delicious berries are full of beneficial phytochemicals, vitamins, and minerals. Wild blueberries are smaller and have more skin than flesh. However, both the wild and the cultivated varieties contain nutrients and taste great. If you can’t find fresh blueberries, you can use frozen. They’re just as tasty and nutritious.
  • Water – You need water for this recipe to cook down the blueberries into a sauce.
  • Maple Syrup – This natural sweetener is a great alternative to refined sugar in many recipes.
  • Cinnamon – This warming spice adds flavor and enhances the natural sweetness of berries and maple syrup.
  • Lemon Juice – Fresh lemon juice adds freshness and balances the flavor of the sauce.
  • Vanilla Extract – Vanilla makes everything taste better. It adds a delightful floral aroma to the sauce.
  • Pinch of Salt – Salt enhances the sweet and succulent blueberry flavor.
  • Arrowroot Powder – Also known as arrowroot starch, this fine powder is made from arrowroot plant roots. Its thickening properties are activated with heat, so it’s good for thickening sauces without cornstarch.

Sweetener Substitutions

Feel free to substitute maple syrup with another healthy, natural sweetener. Agave nectar and date syrup are great natural vegan sweeteners.

You could also use honey (although not vegan).

How To Make Healthy Blueberry Sauce

Here are the step-by-step instructions on how to make this recipe:

  1. Heat the ingredients: In a small saucepan, over medium heat, heat blueberries, a 1/2 cup of water, maple syrup, cinnamon, lemon juice, vanilla extract, and salt. Stir well and bring to a simmer.
  2. Make the arrowroot slurry: While the blueberry sauce comes to a simmer, whisk the arrowroot powder together with 2 tablespoons of water to create a “slurry.”
  3. Dissolve the arrowroot slurry: Once the blueberries begin simmering, let them simmer for an additional minute while stirring, and then slowly pour the arrowroot slurry into the saucepan while whisking continuously.
  4. Add the remaining blueberries: To the saucepan, stir in the remaining blueberries and bring to a simmer. Simmer for 10 or so seconds to warm through, and then remove from heat. Serve warm.

Recipe Tips

You can use fresh or frozen blueberries for this recipe.

Seasonally fresh and juicy blueberries are great, BUT frozen blueberries work just as wonderfully. They’re picked and frozen at their peak, so they have the same great flavor and nutritional value.

However, keep in mind that frozen blueberries will need to be cooked a few minutes longer.

If you want to make a sugar-free blueberry sauce, you can leave out the maple syrup but make sure you’re using the sweetest blueberries you can find! Keep in mind that without maple syrup, the sauce will be thinner.

You can add additional blueberries or more arrowroot slurry to help thicken it more.

Can I do this with raspberries? The Outback in Sarasota Florida uses the most wonderful raspberry sauce to drizzle (I pour) over their delicious New York Cheese Cake!

Hi Mardi! I am not sure if this recipe would work with raspberries. The proportions might be a bit off because raspberries and blueberries have a different consistency. I have another recipe for a raspberry sauce that might work better for you. Check out this post:
