Healthy and Flavorful Copycat Chick-Fil-A Sauce Recipe

I don’t know about you, but I absolutely love Chick-Fil-A and their delicious sauces. However, the problem is that my favorite sauce, Chick-Fil-A Sauce, is not exactly the healthiest option out there. Each packet of the sauce contains a whopping 140 calories, and trust me, one is never enough. That’s why I decided to embark on a mission to create a fast, healthy, low-carb, and keto-friendly version of the famous Chick-Fil-A Sauce. And let me tell you, once you try this recipe, you won’t believe how amazing it is!

This homemade version of Chick-Fil-A Sauce is not only incredibly simple to make, but it also uses readily available ingredients that you probably already have in your pantry. The best part is that it’s much healthier than the original sauce, containing only around 20% of the calories while still delivering the same mouthwatering flavor. So let’s dive into the details and discover how to make this amazing sauce!

What Makes Chick-Fil-A Sauce So Special?

Chick-Fil-A Sauce is a unique blend of flavors that works wonders with almost any dish. At its core, it combines mayo, barbecue sauce, mustard, honey, lemon juice, and spices. This combination creates a versatile sauce that pairs perfectly with chicken, beef, fish, salads, and even other sauces. However, the original sauce’s ingredients also make it quite unhealthy.

Healthier Ingredient Substitutions

To make this copycat Chick-Fil-A Sauce healthier, we’ll be making a few ingredient substitutions. Don’t worry, though, these substitutions won’t compromise the flavor of the sauce. Let’s take a look at the substitutions we’ll be making:

Mayo is the main ingredient that brings a rich and creamy texture to the sauce. However, to reduce the calorie content, we’ll be substituting it with fat-free Greek yogurt. While full-fat Greek yogurt can also be used, opting for the fat-free version allows us to keep the calorie count as low as possible. If you find that the sauce lacks depth without the fat, you can add some optional mushroom powder, which I’ll discuss further down.

BBQ Sauce

Finding the right barbecue sauce for this recipe can be tricky due to the different brands and flavors available. After much trial and error, I discovered that Ray’s Sugar-Free BBQ sauce strikes the perfect balance of sweetness and smokiness without overpowering the other ingredients. It’s important to note that using sauces with strong flavors, such as hickory, can alter the taste of the sauce and turn it into something entirely different.


Mustard is a flavorful and low-calorie condiment that adds a punch of taste to any dish. For this copycat Chick-Fil-A Sauce, we’ll be using regular yellow mustard. While other varieties like dijon, honey, or spicy mustard can be used, they will affect the overall balance of the sauce, so it’s best to experiment with the ratios until you find the perfect combination.

Lemon Juice

The secret ingredient that gives this sauce its unique tanginess is lemon juice. It provides the necessary acidity to elevate the flavors. I recommend using fresh lemon juice or a high-quality not-from-concentrate lemon juice like Lakewood Ranch. If you don’t have lemon juice on hand, you can substitute it with a little vinegar, such as rice wine vinegar, in a pinch.

Honey not only adds sweetness but also contributes to the viscosity of the sauce. To replace it, we’ll be using our favorite low-carb sweetener. Allulose or erythritol are excellent choices. While we can’t replicate the exact viscosity of honey, we’ll make up for it with another ingredient.

Achieving the Perfect Sauce Consistency

The sauce might seem a bit watery without the mayo and honey. To solve this, we can add a touch of xanthan gum, which will thicken the sauce to a more desirable consistency. Sprinkle just 1/32 tsp of xanthan gum at a time to prevent clumping. If you prefer, guar gum can be used as a 1-to-1 substitute for xanthan gum, as they have similar properties.

Don’t Have a 1/32 tsp?

If you don’t have a 1/32 tsp measurement, there are a few solutions. You can use a 1/8 tsp and cut the volume into four equal parts on a piece of paper, resulting in 1/32 tsp. Alternatively, you can multiply the recipe by four and use a 1/8 tsp instead. Lastly, you can consider purchasing a set of tiny teaspoons, which are handy for low-carb and keto cooking and essential for making incredible ice cream.

Enhancing the Flavor with Mushroom Powder

While completely optional, adding mushroom powder to the sauce can take it to the next level. Mushroom powder adds a delightful umami flavor, compensating for the lack of fat. I recommend using 1/4 to 1/2 tsp for the best result. Alternatively, MSG can be used, but keep in mind that the sauce already has a satisfactory level of sodium, so MSG might make it excessively salty.
