Sugar-Free Cranberry Sauce (Low-Carb, Keto-Friendly)

If you've ever wondered whether a classic holiday side like cranberry sauce needs sugar to taste good, this sugar-free cranberry sauce will convince you otherwise.

Bright, tangy, perfectly sweet, and made with real, whole cranberries, this recipe delivers everything there is to love about traditional cranberry sauce-without the blood sugar spike. 

Whether you're planning a low-carb or keto-friendly Thanksgiving menu or an impressive holiday meal, this sugar-free and low-carb cranberry sauce fits beautifully into any holiday spread.

Homemade cranberry sauce is one of the easiest holiday sides to make, and it just doesn't compare to anything store-bought.

I've been making this sugar-free cranberry sauce recipe for nearly a decade now, but never shared the recipe here since it seemed like such a straightforward dish to transform into a sugar-free or low-carb option. 

While it is really simple, there are a few things to consider when making a sugar-free cranberry sauce, and it's much more than just swapping out the traditional sugar for a low-carb alternative. 

why you'll love this recipe

Raw cranberries are low in carbs (8g net carbs per 1 cup serving of fresh cranberries) and only contain a small amount of natural sugar, so a side of cranberry sauce is completely doable on a keto diet! 

While you can typically take your favorite recipe and substitute real sugar for a keto or low-carb sweetener, I do have one key tip for making the best cranberry sauce this holiday season. 

Choose your sweetener wisely. Out of all of the keto-friendly sugar substitutes out there, my favorite is a blend of monk fruit sweetener and allulose because it creates a smooth, glossy finish without the crystallizing that often happens with other sugar alternatives.

Sweeteners that contain erythritol can leave you with a gritty sauce since the ingredient crystallizes after it's chilled. 

If you'd like to make a cranberry sauce with allulose only, you can certainly modify this recipe. Simply increase the amount of sweetener since pure allulose is not quite as sweet as a monk fruit and allulose blend. 

This sugar-free cranberry sauce is:

• naturally low in carbs and free of added sugar
• Easy to make with simple ingredients
• A great way to enjoy a holiday staple AND blood sugar balance
• A foolproof recipe thanks to the sweetener used.

the ingredients

Here's a look at the main ingredients you'll need for this homemade sugar-free cranberry sauce:

• Fresh cranberries: Preferably organic, if you can find them. 
• Orange: You'll need fresh orange juice and a little zest for extra orange flavor. 
• Granulated monkfruit sweetener with allulose:  This combination of low-carb sweeteners is my favorite due to its clean flavor and the fact that it dissolves well in the sauce. 
• Flavor add-ins: Ground cinnamon and vanilla extract are technically optional, but they add a little something extra without overpowering the cranberry flavor. 

how to make sugar-free cranberry sauce

Here's a look at the easy process but be sure to view the printable recipe card at the bottom of the page for all of the details: 

1. Simmer the base: Add the cranberries, orange juice, orange zest, and water to a medium saucepan. Bring to medium heat and cook for about 5 minutes, allowing the berries to begin softening.
2. Sweeten and thicken: Stir in the monkfruit-allulose blend and cinnamon. Continue cooking for another 5-6 minutes, or until the cranberries burst and the mixture thickens into a glossy sauce. You'll hear the berries pop as they cook and you can use a wooden spoon to gently mash them and help break them down. 
3. Finish with vanilla: Remove from heat and stir in the vanilla extract.
4. Chill and set: Let it chill at room temperature for about 20 minutes. Transfer to a container and refrigerate for at least 2 hours to allow the flavors to deepen and the sauce to fully thicken. Serve with a garnish of cinnamon sticks and more orange zest, if desired. 

recipe tips for the best keto cranberry sauce

• Taste and adjust: Cranberries vary in tartness, so feel free to add a little extra sweetener if needed.
• Don't skip the chill time: The sauce thickens significantly as it cools.
• Make it chunky or smooth: The berries will naturally break down as they cook and it becomes easy to lightly mash them with a spoon. If you don't care for a thicker, more rustic texture, you can also blend the cranberry sauce and even push it through a fine-mesh strainer for an extra-smooth finish. 
• Spice it up: Try cloves, nutmeg, or cardamom for a more festive, spiced version.

storage and make-ahead

• Store leftover sauce in an airtight container for up to one week. I sometimes make a double batch because Thanksgiving leftovers are never the same without a little spoonful of leftover cranberry sauce on the side. 
• If you're making this to serve with a Thanksgiving meal, it's the perfect side to make ahead! Just like regular cranberry sauce, this sweet flavors deepen over time so feel free to make this up to 1-3 days in advance. 

substitutions

• If you're looking to reduce the total carbs even more, you can substitute the orange juice for half water/half lemon juice, then add in a splash of orange extract. 
•  A monkfruit/allulose blend is my favorite sugar-free sweetener to use because it dissolves so well and doesn't have a strange aftertaste. If using pure granulated allulose, you can increase the amount to 1 cup.

serving suggestions

This sugar-free cranberry sauce is perfect on for a Thanksgiving turkey, pork tenderloin, or even spooned over a sweet treat like my keto and high-protein cheesecake.

It also pairs beautifully with holiday appetizers like baked brie, whipped mascarpone dip, or meat-and-cheese boards.

This upgraded classic is a great recipe for a holiday essential that packs flavor-not sugar. It's simple, fresh, and guaranteed to become one of your most-loved holiday sides.
