Dress up any meal with this bright and zesty sauce that’s quick, easy, and free of the added sugars in store-bought versions!
Cranberry sauce was a Thanksgiving afterthought for my family. Once everything else was on the table—roasted turkey, baked yams, several bowls brimming with savory stuffing, a basket of homemade rolls—someone would notice its absence. It was usually my dad who’d ask about it, prompting one of us kids to fetch the can from the cupboard. We’d chuckle as the semi-solid, can-shaped “sauce” plopped out onto a dish. Later, I’d scrape its congealed remains into the trash. I think my dad was the only one who actually ate any of it.
This keto cranberry sauce recipe hardly seems related to that store-bought version. My low-carb partner made it the first time we cooked a full roasted chicken dinner together. I never even thought about including cranberry sauce because it was early spring and that condiment was firmly connected to winter holidays in my mind. He’s low-carb, and I’m supportive, so I gave it a try. To my surprise, it tasted nothing like the gelatinous goop from my childhood! The texture was thick and chunky, kind of like a chutney. And the flavor profile was definitely more tart than sweet, but pleasantly so, with a hint of cinnamon adding warmth and the bright acidity of lemon zest keeping it light. It brought just the right contrast to our savory feast of roasted chicken and mashed cauliflower!
The kicker was how quickly and easily the recipe came together. I thought it would be much more complicated! In about the same amount of time it took to find and open that can, we had this fresh, colorful, flavorful sauce on the table.
Fresh or frozen cranberries
Thanksgiving is the only time I see fresh cranberries at my local grocery store. But the frozen ones seem to be available year-round. If that’s what you have on hand, they’ll work just fine in this recipe! Add them straight to the pot—no need to thaw—but expect to simmer them a few minutes longer. Frozen berries release more moisture initially than fresh ones, which requires more time to cook off. The final flavor remains bright and tangy either way, and both options break down just as easily. For the best results, let the sauce’s texture be your guide for adjusting the simmering time. A silky-smooth sauce may take a minute or two more than the recipe suggests, while a chunkier, rustic sauce is ready as soon as the cranberries pop and the juices start to thicken. And keep in mind that the sauce continues to thicken as it cools, so take it off the heat when it’s a bit looser than your ideal final texture.
How do I store leftovers?
Let your keto cranberry sauce cool completely before storing it in an airtight container or jar. It’ll keep in the fridge for up to 14 days or in the freezer for up to 6 months. Thaw overnight in the fridge. The texture may loosen a little after freezing, but a quick stir or gentle reheating on the stovetop should restore its consistency.

Keto Cranberry Sauce Recipe
Ingredients
- 1/2 cup water
- 1/3 cup powdered erythritol
- 1 teaspoon liquid monkfruit
- 1/8 teaspoon salt
- 1/8 teaspoon cinnamon
- 1/2 teaspoon lemon zest or orange zest
- 1 12-ounce bag of fresh cranberries
- 1 tablespoon fresh lemon juice
Instructions
- In a medium saucepan over medium heat, combine the water, erythritol, liquid monk fruit, salt, cinnamon, and zest. Stir until the sweetener is fully dissolved.
- Add the cranberries and lemon juice to the pan. Cook uncovered for about 10-15 minutes, stirring occasionally. The cranberries will burst and release their juices into the sauce. The sauce is done when it has thickened enough to coat the back of a spoon. It will thicken further as it cools.
- Remove pan from heat. Adjust sweetness if needed. If desired, use an immersion blender to achieve a smooth texture or a potato masher for a chunkier sauce. Serve warm or chilled.
