Healthy Keto Salad Dressing Ingredients

Fresh herbs - This is where you get to be creative. Use any type of herb that is growing like crazy in your garden. I use equal amounts of fresh cilantro and basil as that is what my garden was producing. I then added some thyme, a little tarragon, and parsley.
Red Pepper Flakes - This ingredient adds a little kick to the whole thing!
Garlic - 3 cloves of garlic is just the right amount to give this healthy keto salad dressing the garlicky flavor that it needs. If you have any Homemade Garlic Confit, I absolutely suggest using it in this recipe.
Vinegar: I like to use White Wine Vinegar, Red Wine, or Rice vinegar, just to taste, to help round out the flavours. If you don't have any of these ingredients, you could always try using apple cider vinegar.
Olive Oil: I like to use Extra Light virgin olive oil but other oils such as Walnut oil or Avocado oil will work well.
Sweetener - This ingredient is completely optional. If I am craving a sweeter fresh herb dressing, then I will sometimes add some liquid Monk Fruit drops, a little powdered allulose or even some Sugar-Free Honey.

How to make this Healthy Keto Dressing

There are 2 different ways by which you can make this keto fresh herb sauce, either using a food processor or an immersion blender.

Using a Food Processor:

Add the vinegar, onion, garlic, salt, and red pepper flakes to the bowl of a food processor. Process until the onion has broken down.

Process until desired consistency is reached. Taste and add additional salt, pepper, water, or oil to achieve the taste and thickness you want.

Using an Immersion blender:

An immersion blender (a stick blender) makes this healthy keto salad dressing easy to whip up in under 5 minutes!

How should this fresh herb dressing be stored?

Place the fresh herb sauce in an airtight jar. Place it in the fridge and it should last up to 2 weeks.

Can I freeze this healthy keto dressing?

I do not suggest freezing this salad dressing as the consistency will be altered.

Can I freeze leftover fresh herbs?

Freezing works well for herbs like parsley, dill, basil, chives lemon balm, mint or tarragon.

Can I eat the stem of herbs?

Yes! Some herb stems will get woody so I do not suggest eating those stems. Also, the stem from parsley has a slightly bitter taste so I avoid using the stems in dishes like this fresh herb sauce.

Which oils work best for making keto salad dressings?

Oils rich in monounsaturated fat, phytochemicals, and alpha-linolenic acid are best for salad dressings. These include extra virgin olive, canola, peanut, flaxseed, walnut, hemp, avocado, and almond oils.
