Why This Recipe is a Winner

  • Cornstarch is added to thicken the berries’ juices.

Key Ingredients

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

  • Lemon — We’ll use both the zest and the juice of the lemon.
  • Oats — I used rolled oats for this recipe, but you can substitute instant oats.
  • Chia — We’ll add some ground chia seeds to create a thicker texture. You can use whole chia seeds; I just prefer ground because it creates a smoother finished texture.
  • Syrup — I used maple syrup, but you can substitute agave nectar.
  • Milk — We’ll use almond milk for the best overnight oats! Substitute your favorite plant-based milk.
  • Yogurt — I love adding some plant-based yogurt (plain, unsweetened) for an even more tangy flavor.
  • Protein Powder — I add some vanilla protein powder for increased flavor and nutrients. If your protein powder is not sweetened, you may want to add an extra teaspoon or two of sweetener.
  • Cornstarch — We’ll use cornstarch to thicken the lemon curd topping.
  • Turmeric — A pinch of turmeric makes that lemon curd sunny yellow.
  • Cornstarch — This my thickener of choice. Substitute arrowroot powder or tapioca starch.
  • Granulated sugar — for a healthy blueberry sauce, use either a zero-calorie sweetener (such as monkfruit) or use coconut sugar.
  • Water — adding just a bit of water creates a nice consistency.
  • Blueberries — Fresh or frozen blueberries work great.
  • Lemon juice — lemon and blueberries are a nice flavor combination and we’re adding just a bit of lemon juice (fresh or bottled) to enhance the sauce’s flavor.

What Blueberries are Best for Blueberry Sauce?

When buying fresh blueberries, choose berries that are plump and smooth-skinned. The color of the berries is an indicator of ripeness (not the size of the berries), so choose berries that are deep purple-blue. You can use fresh or frozen blueberries with this recipe. Frozen blueberries are great because they’re frozen at the peak of ripeness, and they hold their shape better while cooking.

How to Make Blueberry Sauce

Let’s talk about making this blueberry reduction.

Here are two ways to make this tasty syrup:

  1. Stir cornstarch to a saucepan along with sugar and water.
  2. Add the blueberries.
  3. Stir it together and then turn up the heat up to medium to bring it to a boil.
  4. Reduce heat to medium-low and simmer for a minute or two until the sauce thickens.
  5. Remove the pan from the heat and add the lemon juice.
  6. Transfer it to a lidded jar and set it aside to cool completely.
  7. Add the lid and refrigerate until you’re ready to serve.

Marly’s Tips

You can add different seasonings, such as a ½ teaspoon of vanilla, lemon zest, a few sprigs of dried thyme, rosemary, or even basil. There are lots of great flavor profiles that complement blueberries.

Making Blueberry Sauce in a Microwave

Here are the steps to make your blueberry sauce in the microwave:

  1. Use a sturdy pyrex measuring cup or a tall microwave-safe bowl.
  2. Stir together the ingredients as directed above.
  3. Microwave for one minute, then stir.
  4. Repeat this in 30-second increments until the sauce thickens.

How to Enhance Blueberry Flavor

You can add a blueberry flavor boost by adding a bit of coriander to your blueberry sauce. I’d suggest adding no more than a quarter teaspoon of dried coriander is necessary. We want to enhance the flavor, not overwhelm it.

In addition, the lemon juice also helps enhance the flavor in this tasty blueberry sauce recipe.

Storage Tips

Once the sauce cools, pour it into a sealable container, like a mason jar and store it in the fridge. This sauce will keep in the fridge for up to 10 days.

Frequently-Asked Questions

How do you thicken a berry sauce?

Cornstarch is a great thickener for a berry sauce because it creates a perfect consistency. If your sauce is too thick, add a little more water or if it’s too thin, you can add cornstarch combined with water and bring the sauce to a boil.

How can I thicken sauce without cornstarch?

Cornstarch is a favorite thickener, but there are options you can use besides cornstarch. For example, agar agar flakes make a great zero carb thickener. You can also use arrowroot powder and even tapioca starch as a thickener.
