Recipe FAQs
What is ranch dressing?
It is a combination of mayo, sour cream, and spices that's used as a dip for veggies or as a salad dressing. In fact, it's the most popular dressing in the United States! In my recipe, I add buttermilk, lemon juice, and freshly minced garlic for a real zesty kick and amazing flavor.
What is it made of?
Ranch is made from a combination of mayonnaise and sour cream (or Greek yogurt). It's seasoned with dried spices like parsley, dill, onion powder, salt, and pepper. For this version, we also add a splash or two of buttermilk to thin it out and to add extra tang.
When and where was it invented?
You might be surprised to find out that ranch was invented by Steve Henson in the 1950s when he was working in a remote part of Alaska. Steve and his wife Gayle opened a dude ranch called Hidden Valley Ranch in California in 1954, where tourists tried this condiment and loved it. Eventually, it was made commercially, and grew in popularity throughout the whole United States.
Will it make you fat?
It is fine to be enjoyed in moderation. A serving size of 2 tablespoons (homemade) has 137 calories, 15.7g of fat, and 1g of carbs. That's definitely a little healthier than Hidden Valley Ranch, which has 140 calories, 14g of fat, and 2g of carbs. The homemade version has no unhealthy preservatives or chemicals in it like the packet or bottled version does.
Is buttermilk dressing the same as ranch?
Buttermilk dressing is slightly different in that it doesn't contain herbs.
What is the best ranch salad dressing?
The best kind is the one you make yourself! I think that our recipe tastes 10 times better than the store bought. It's got a nice kick from the fresh garlic and lemon juice, plus a thick, creamy texture and tangy flavor.
How do you make it ranch seasoning?
Making your own seasoning packet is a quick and healthier than buying store bought! Simply mix together the dried spices in the recipe (parsley, dill, onion powder, salt, and pepper) and set aside to use later. Feel free to add dried chives, garlic powder, or dried minced onion if that strikes your fancy.
You can also add buttermilk powder to the spice mixture. This means that you can mix the dried spices with mayo and milk instead of having to use real buttermilk. For more details on making your own mix, check out Ali's recipe and tips.
Can I make my own buttermilk?
Yes, you absolutely can. Pour 1 tablespoon (15 ml) of lemon juice or distilled white vinegar into a 1-cup (240 ml) measuring cup. Fill the measuring cup the rest of the way with milk, then gently stir and let it stand at room temperature for 10 minutes. This allows the milk to curdle.
If you can run to the store to get some cultured buttermilk, I'd recommend that over using the substitute. Store-bought buttermilk has healthy probiotic cultures, a distinctive tangy flavor, and thick texture that you don't get in this quick homemade buttermilk.
Store
How long does this dressing last?
It will last for about 1 week in the fridge. Seal it tightly inside of a mason jar to retain freshness and keep out odors.
Can you freeze it?
No, you shouldn't freeze it. The mayo and sour cream will separate once they're thawed, giving the dressing an undesirable consistency. It's best to make enough that you can eat within a week, and just store it tightly sealed in the fridge.
Expert Tips
- Use fresh garlic and lemon juice for the best flavor. It's the secret to great-tasting ranch!
- Use the best quality mayo. Our favorite is Duke's, but you can always make your own.
- Don't have sour cream? Substitute with an equal volume of Greek yogurt.
- Run out of buttermilk? Use the separated liquid from the sour cream carton, whole milk, or heavy cream instead. You might want to add an extra dash of lemon juice for tang.
- Adjust seasonings to taste. This is an important step, as you might want the flavor to be more lemony or garlicky.
- Add the buttermilk at the end. This is just to thin it out and add extra tang.
