The recipe for Sugar-Free Strawberry Sauce

This recipe makes a crave-worthy sauce loaded with strawberry flavor. It’s easy to make, takes only a few minutes and can be made with either fresh or frozen strawberries. 


This sauce is gently cooked on the stove-top to thicken it slightly and meld the flavors together. 


Whether you choose to make the basic sauce or the balsamic peppered variation, you’ll find yourself spooning this sauce over everything sweet!


The Inspiration for Sugar-Free Strawberry Sauce

In case you haven’t noticed, I’ve been on a strawberry kick lately. I’ve created a recipe for low-carb strawberry mousse, low-carb strawberry cream pie, and now this strawberry sauce. 


This sauce was actually inspired by a dessert at a tiny restaurant in Monroe, NC called Bibi’s. The chef, Jason, used to serve peppered strawberries over ice cream. It seemed like a strange flavor combination to me, but the waiter convinced me to try it and I’m glad I did!


While Bibi’s no longer exists, I still crave that peppered strawberry goodness and brought it back to life in this recipe.

Why do you put pepper on strawberries?

While strawberries and cracked black pepper might seem like a strange combination, the flavors actually work quite well together.


The pepper helps to neutralizing the tartness. This brings out the natural sweetness of the berries. In addition to neutralizing the tartness, the black pepper also balances the sweetness which allows all of the subtle fruit flavors to shine. This creates a complex blend of flavors that will have you coming back for more.

Can  you make this Keto-Friendly Strawberry Sauce from Frozen Strawberries?

You can use either fresh or frozen strawberries to make either variation of this sauce. Either choice makes a delicious sauce. 


You do not need to defrost the frozen strawberries completely before making this recipe, but you will need to slice them first.


How to slice frozen strawberries

You will need to slice the strawberries for this recipe. While slicing fresh strawberries is easy, slicing frozen strawberries presents a bit of a challenge. In order to make this easier, I recommend allowing them to soften slightly by allowing them to sit at room temperature for 10-15 minutes.


Do not allow the berries to defrost completely. You don’t want them rock-hard, but they should still be mostly frozen. If they are completely thawed, they will turn into mush when you try to slice them.


To slice them berries, you will want to use a cutting board and a sharp knife. Before beginning, place a damp cloth under the cutting board to stabilize it. 


After your cutting board is properly stabilized, you’re ready to cut the berries. First, place a berry on the cutting board on the flattest side of the berry so that it doesn’t roll. 


Next, hold the berry still with one hand, being careful to keep your fingers curled back away from the knife. You will want to slice the berries length-wise. The slices should be about 1/8 to 3/16ths of an inch thick.

How to serve Keto-Friendly Strawberry Sauce

No matter which version of this sauce you choose to make, you will find that it’s a super-versatile sauce. You can spoon it over our grain-free waffles, or our chocolate waffles. It would even be wonderful over our keto-friendly banana pancakes. You might want to leave the nuts out of the banana pancakes if you decide to do this.


One of my favorite ways to serve this sauce is over low-carb vanilla ice-cream. It also works well to sweeten up and flavor some plain greek yogurt. These options are both shown in the photos.


The classic version of the recipe would be delightful layered with my recipe for lemon chia pudding or spooned over a serving of my keto-friendly chocolate pudding.


How long does strawberry sauce last?

You’ll want to put any leftover sauce in an air-tight container and store it in the refrigerator. This sauce should last about 3 or 4 days.

Can you freeze strawberry sauce?

If you need to store the sauce for more than 3-4 days, you will need to freeze it. To freeze the sauce, allow it to cool, then simply it to a freezer-safe container and place it in the freezer. 


Frozen strawberry sauce should last for a few months.


Final Words

I hope this strawberry sauce brightens your day and adds flavor to your foods. Enjoy!
