Blueberry Coulis

This blueberry coulis is the perfect addition to anything from breakfast to dessert! It’s a handful of ingredients, one pot, and it only takes 15 minutes.

This blueberry coulis is as versatile as it is simple. Its balance of tart and sweet will elevate and complement so many dishes! It takes under 15 minutes and scales up or down without any adjustment to technique. This sauce can bring all the other elements of a dessert together into one harmonious dish.

If you are already working with blueberries, my lemon blueberry cookies, blueberry pie recipe, or this berry trifle are worth having in your little black book as well!

Ingredients & Substitutions

• Blueberries: Fresh or frozen, both work here. If you are using frozen, do not thaw them first; add them straight to the pan and expect a minute or two of extra cooking time as the liquid releases.
• Lemon zest and lemon juice: The zest adds floral, aromatic brightness that juice alone cannot replicate, which is why I always use both, like in this lemon pound cake. Zest before you juice, and use a Microplane so you get the fragrant outer layer without any bitter pith.
• Sugar: Sweetens the sauce and helps draw out the berries’ natural juices as they heat. I start with the listed amount and taste before I start cooking, adding a little more if the fruit is particularly tart. The right balance is bright, not cloying.

How to serve Blueberry Coulis

• A simple garnish for cakes or cupcakes: Add a spoonful to complement this angel food cake, flourless chocolate cake, or white cake recipe. Or fill these coconut cupcakes, vanilla cupcakes, or these lemon cupcakes. You’ll want to thicken the sauce more by cooking it longer for this application. Otherwise, the juices will soak unattractively into the cupcake
• Ice cream topping: Pour it over vanilla bean ice cream for a healthier alternative to chocolate sauce. Or pour it on with the hot fugde sauce, I’m not judging!
• Perfect for brunch:  Add it to your morning like in these pumpkin yogurt parfaits or on top of these lazy Sunday buttermilk waffles! Bonus points for a crumble of honey granola! Now that is a breakfast worth getting up for.
• Dessert topping: Bake up a light, airy pavlova cake and top it with some easy lemon curd and a particularly generous spoonful of this blueberry sauce, and you’ve got an elegant, show-stopping dessert! Or go the no-bake route and try a buttermilk panna cotta or lemon posset.
• Turn a bar or cookie into a full dessert: Make a no bake lemon bar or butterscotch brownies a full dessert with this blueberry coulis! The undeniably perfect tart finish to dinner.

Professional Tips

• Taste before you cook. Before you cook the sauce, grab one blueberry and taste it against the lemon-and-sugar balance in the pot, adjusting before cooking costs you nothing, and adjusting at the end can throw off the consistency.
• Use a light-colored pan if you have one. It lets you see the color of the sauce as it cooks and catch the moment the juices shift from thin and watery to glossy. I always use my stainless saucier for this reason, and the difference in control is noticeable.
• Do not walk away once it starts to bubble. The sauce thickens quickly once the berries begin to pop, and it can go from perfectly saucy to overcooked jam in under two minutes. Stay at the stove and test the consistency on the back of a spoon every thirty seconds toward the end.
• Cool it quickly if you are making it ahead. The recipe holds for two weeks, but only if you bring it down to 40°F within two hours. Set the container in an ice bath to speed that process before sealing and refrigerating.

How to Make Blueberry Coulis

This comes together in under 15 minutes, so have everything prepped and ready before you turn on the heat.

Step 1: Combine all ingredients in a small saucepan. Add the blueberries, lemon zest, lemon juice, and sugar to a small sauce pot and give everything a quick stir.

Zest the lemon before you juice it. Once it is juiced, getting a clean zest off a collapsed lemon is technically possible but deeply unpleasant.

Step 2: Start the blueberries over medium-low heat. Turn the heat to medium-low and let the blueberries slowly release their juices. If you are using frozen berries, this is the thawing phase, which takes a few minutes longer than with fresh berries, and the mixture will look watery and pale at first, which is completely normal.

Step 3: Increase the heat and cook until the sauce thickens. Once the juices are flowing, raise the heat to medium and cook, stirring occasionally, until the blueberries begin to pop and the sauce visibly reduces and thickens. To test the consistency, drag your finger through the sauce on the back of a spoon. When it holds a clean line without running back together, it is ready. You can pull it earlier for a looser, pourable sauce or keep cooking until it approaches a jam-like set.

Step 4: Cool or use immediately. Use the sauce hot if you are assembling right away, or transfer it to a shallow container to cool quickly if storing.
