Ranch is my favorite dressing in the world (although I use it more as a dipping sauce) and Homemade Ranch easily blows the store bought versions out of the water! (Makes about 2 cups)
Let chill in a covered container in the fridge for 24 hours.
Notes
If you're short on time - try this shortcut method! 3/4 cup mayo, ¼ cup sour cream, 1 cup buttermilk, 1 oz dry ranch seasoning mix, 2 cloves grated garlic
Storage
You can store your Homemade Ranch in an airtight container in the refrigerator for up to 2 weeks.Here are some tips to ensure your Homemade Ranch stays as fresh as possible:
Make sure your Homemade Ranch container is well sealed.
Avoid dipping directly into the jar and only use clean utensils - any bacteria from food or used utensils will make your Ranch go bad faster.
Don't leave your Homemade Ranch out - put it back in the refrigerator after opening or using, as the sour cream or buttermilk can lead to your Homemade Ranch going bad if left out.
