Blueberries
Granulated sugar
Cornstarch (also known as corn flour in the UK)
Sliced sourdough bread
Plain Greek yogurt
Honey

Both fresh or frozen blueberries will work for this recipe. If you’re using frozen, there’s no need to thaw! For fresh blueberries, rinse gently before using, and make sure to remove any wrinkly berries.

Flavored yogurt can be used, but keep in mind it will have added sugar. Vanilla skyr (thick Icelandic yogurt) is one of my favorites!

How To Make Homemade Blueberry Sauce

A pot filled with cooked blueberries, creating a dark, rich mixture. The pot has a white interior and a wooden handle. A blue and white striped cloth is partially visible next to the pot on a white marble surface.

Step 1: Cook The Blueberries With Sugar And Cornstarch

Start by adding your frozen blueberries and sugar to a small saucepan over medium heat. Stir occasionally as the blueberries release their juices and the sugar dissolves, cooking for about 2-3 minutes. While that’s happening, mix cornstarch with cold water in a bowl and whisk until smooth.

Once the blueberries are bubbling, pour in the cornstarch slurry and stir for another 1-2 minutes until the sauce thickens to a jam-like consistency. Remove from heat and let the sauce cool for 5 minutes to set. It will continue to thicken as it cools.

Step 2: Prepare The Toast

While your homemade blueberry sauce recipe is cooling, toast your sourdough bread. Place the slices in your toaster and set the toaster to your preferred setting (light or dark toast). Toast the bread for about 3-5 minutes, or until golden brown and crispy.

Step 3: Spread With Yogurt

Spread a thick layer of Greek yogurt over each slice of toast. Don’t be shy with it because this is your creamy base that balances the sweet blueberries. It’s like the perfect cozy pillow for your fruit.

Step 4: Add The Blueberry Sauce And Honey

Now, grab that delicious blueberry sauce and spoon it generously on top of your yogurt-covered toast. Make sure to get a nice, even layer so every bite has that sweet, juicy blueberry goodness.

To give that extra touch of sweetness, drizzle honey over the blueberries. It adds that perfect final touch and really elevates the flavors. And just like that, you’ve got a warm, comforting breakfast that’s ready to enjoy!

Tips and Variations

Swap out the sourdough bread for a gluten-free version. There are great gluten-free sourdough breads available, or you can use any gluten-free bread you love.
For a dairy-free version, use coconut yogurt instead of Greek yogurt, and ensure your bread is dairy-free as well.
To make it low-sugar, cut back on the sugar in the blueberry sauce or use a sugar alternative like stevia.
Sprinkle some chocolate chips or chopped nuts for extra flavor.
Add a dash of ground cinnamon in the blueberry sauce to add a cozy, spiced note.

Storage and Reheating

Store any leftover sauce in an airtight container in the fridge for up to 4 days. This also works great for meal prepping ahead of the weekend!

If you want to keep it longer, you can freeze it in a freezer-safe container for up to 3 months. Be sure to leave some room in the container to allow for expansion during the freezing process. If you have SouperCubes, they work great for making smaller portions of the sauce to serve for one or two.

Thaw frozen sauce overnight in the refrigerator.

Heat any leftovers gently in a small saucepan on the stove, stirring to help warm evenly. If you’re in a pinch you can use the microwave, but be sure to cover the bowl with a paper towel to prevent splatters!
