The BEST Skinny Ranch Dressing (3 ingredients)


Best Skinny Ranch Dressing
I’m so excited to share this 3 ingredient dressing! Your search is over…This is the most amazing, easy-to-make, gluten-free, skinny ranch dressing!!! It tastes just as good as any high-fat dressing but with a fraction of the fat and calories. In the past, I’ve shared my skinny ranch dressing recipe but it called for many dry ingredients. In addition, you needed xanthan gum to thicken it. I got back in the kitchen and created a new, easier, and much skinnier recipe. Each 2 tablespoons serving has just 30 calories, 2 grams of fat. So delicious as a dressing, dip, topping for potatoes, and more. The possibilities are endless. I always have some on hand in my refrigerator. It’s a must-try!!!

  • cups buttermilk
  • ½ cup Best Foods (Hellmans) light mayonnaise see shopping tips
  • 1 oz package Hidden Valley Ranch Original Ranch salad dressing & seasoning mix do not use buttermilk mix


  • In a medium bowl, add all ingredients. Using a whisk, mix together until completely blended.
  • Refrigerate at least 30 minutes to thicken, before using. To thicken quicker, place in freezer and set timer for 15 minutes. Store dressing in the refrigerator for at least 2-3 weeks. The shelf life depends on the expiration date of your buttermilk.



Food Facts
The original ranch dressing was created in the 1950s by Steve and Gayle Henson at their dude ranch near Santa Barbara, California.  It was called the Hidden Valley Guest Ranch.  Today ranch dressing dominates the dressing aisle of the supermarket. And it’s gluten-free!
Buttermilk, in the old days, was the liquid left over after butter was churned. Today it’s nonfat or reduced-fat milk that has been treated with special bacteria which causes the milk to thicken and gain a tangy flavor.

Shopping Tips
Best Foods Light Mayonnaise (Hellmans) is the only brand I recommend. I’ve tried several different brands and Best Foods Mayonnaise is the best tasting for this recipe! Best Foods Canola Mayonnaise also tastes great for this recipe.

Healthy Benefits

This dressing contains a lot of buttermilk, which, despite its name, contains very little fat.  It is loaded with bone-building calcium and has a great deal of vitamin-B, which facilitates nerve function and promotes healthy skin and good vision. Buttermilk, even if the container doesn’t say it is low fat.
How Long it Keeps
This dressing will last as long as the buttermilk you buy. I always buy the longest date (longest life or best buy) when at the supermarket. Reach to the back of the row. Most buttermilk’s life is for 2-3 weeks.
*Be sure to use a package of Hidden Valley The Original Ranch Salad Dressing & Seasoning Mix. It’s a 1 oz pkg. Do not use the Buttermilk package. It’s much smaller than 1 oz. The dressing won’t end up be thick enough or flavorful enough!
I love using these reusable deli containers to store this dressing.

  1. Is it regular buttermilk? Or should I get light? Or fat free? There are all 3 options so I’d like to know which one works best for the recipe

  2. Most buttermilks are low fat and range from 5g-2.5g of fat per cup. Kelsey, any of these will work. I would not use a fat-free buttermilk.
    All the best,

  3. Not great frozen Debbi. The buttermilk breaks down. The good news is it will last several weeks in the fridge. Try to use a buttermilk with the longest best buy date.
    All the best,

  4. I just read an article about Ranch dressing and Steve actually invented it in Alaska, where he was working for a time. He was the cook for the crew somedays. Fresh herbs weren’t available so he experimented and they loved it. Then he and his wife bought a top-down rambling ranch, renamed it Hidden Valley, and served it in their restaurant. Guests always requested some to take home and they would give them a mason jar full. After making vats of the stuff night after night, they created the packets which we still love today!

  5. I’m so glad to hear it Kelly. Thank you! It’s by far the most popular recipe on Skinny Kitchen.
    All the best,

  6. So you are using the dry mix HV that calls for milk, correct? Instead you are using buttermilk. Also, you are using a light mayo instead of regular mayo. Just want to make sure I have it correctly. I had always used the milk and regular mayo when I couldn’t find the HV buttermilk version Any longer. However when I tried it with milk and low-fat mayo it just wasn’t any good. So the secret must be to use the buttermilk and low fat mayo together.

  7. It’s a must to use buttermilk not regular milk. I agree, milk doesn’t taste good. And yes, use light mayo. I highly recommend Best Foods light. It’s also called Hellmans Light. This brand is the very best!
    Good luck Debbie!
    My best,

  8. Nancy,
    Thank you so much for all you amazing post. Your recipes have gotten me out of boring humdrum meals.Congratulations on you success and taking the the time to personally answer every ones comments.
    Best regards,
    Roberta Kluck

  9. Sounds good but I also love to just mix the dry ranch dressing mix into fat free Greek yogurt for 0 WW points..

  10. Roberta, you are the sweetest. Thank you so much. As you know, I do answer every comment and email I receive. It’s my great pleasure.
    My very best,

  11. So sweet Joyce. That makes me very happy. Sorry but I don’t have a Skinny Kitchen cookbook.
    All the best to you,

  12. Could you please tell me what the fat gram content would be for 2 T’s if regular Best Foods mayo was used?
    I just love the taste of the real mayo, and my issue is more fat ingestion than calories. Can you help? Thank you so much, Nancy.

  14. Thank you so much, Nancy. I am working on finding a way to enjoy a lower fat diet, and you are a great inspiration. Thank you so much.


  15. I tried this recipe with the buttermilk mix (which was still thick) and found it to be even tastier! Is there any difference in the nutritional facts? Thanks!

  16. That’s great to hear Kelly. I’m pretty sure the nutritional facts are the same for the original dry mix or the buttermilk mix.
    All the best,

  17. So happy you love this dressing Kathy. I’ve tried making this dressing with Greek yogurt but didn’t like it. You might try 1/2 yogurt and 1/2 mayo.
    All the best,

  18. I’ve never tried this recipe with almond milk so not sure it would work compared to buttermilk. That said, the calories would be much less. One cup of buttermilk usually has 100-120 calories per cup and unsweetened almond milk has 30 calories per cup.
    My best,

  19. I tried it with unsweetened almond milk and it came out GREAT!!! Just a little thin so next time I will put a little less milk. May 3/4 cups instead of a full cup.

  20. I know it’s such a small amount of MSG in this dry mix and most people don’t have a problem with it. Joan, you might try McCormick’s dry Ranch Dip Mix instead. It doesn’t contain MSG. I haven’t try it yet.
    I hope this helps!
    My best,

  21. Sorry Lori but I’ve never tried this dressing with powdered buttermilk. And actually, I’ve never tried powdered buttermilk before.
    My best,

  22. Nancy,
    Are you using the 1% buttermilk or whole buttermilk ? I ran through the recipe builder on my WW app using whole buttermilk because, for whatever reason, low-fat buttermilk has become harder to find in my area. Only one grocery chain carries it here. I just wondered about the thickness of using one vs. the other.
    Best wishes,

  23. Susan, I used reduced-fat buttermilk, either 1% or 1 1/2%. It turns out plenty thick. If you like your dressing even thicker, you can use 1 1/4 cup buttermilk and use 1/2 cup nonfat Greek yogurt plus the 1/2 cup mayo and seasonings.
    I hope this helps.
    All the best,

  24. I want to try making this with milk kefir. I make my own with fat free milk. Oh! it’s so good! To me it tastes like a more tart buttermilk. But after you drink it for a while you don’t taste the tartness very much. i think I am addicted to the effervescence of it. I want to start cooking with it too so this sounds like a good recipe to start with.

  25. Do you know the WW Smart Points for the Purple Plan. I noticed your recipes don’t include the Purple Plan. Thanks if you can help out with that. Diane

  26. Sorry Diane, but at this point, I’m only including Blue and Green points. For all of these years, I’ve used a different program than WW to input all of my recipes to do the nutrition facts and points

    I have hundreds of recipes and don’t have the time to input them into WW to make the calculations for the purple plan. Maybe in the future.

    My best,

  27. I just saw your recipe for the ranch dressing. I would like to know if you can make your own buttermilk. I just add lemon juice to the milk to make it buttermilk. Would thst work or do i have to really buy buttermilk for this recipe.

  28. Actually, Shirley, I’ve never made my own buttermilk. It’s so easy to buy it since it’s readily available. So even if you make your own, I’m not sure if it will work with this dressing. If you give it a try, I’d love your feedback.
    Best of luck!

  29. Does this freeze well? Since I’m the only one that will eat it I was thinking of freeze individual serving sizes and just defrosting when needed. So there is less waste.

  30. I’ve never tried freezing this dressing, Jacquie. I’m guessing the buttermilk will break down. If you buy a container of buttermilk that will last 2-3 weeks, you can enjoy this dressing without wasting it. The dressing will keep as long as the buttermilk.
    My best,

  31. My calculator on WW says 2tbs up to 3tbs – is 2 points on blue. Buttermilk 12, Mayo 11, packet 6 – divided by 36.

If you make this recipe, let me know how you liked it. Leave me a comment below or give it a rating. Thanks so much. Happy Skinny Cooking!
