Collect all the ingredients on your countertop. This makes the process smoother and saves you from hunting down items mid-recipe.

In a medium mixing bowl, combine the sour cream, buttermilk, and mayonnaise. These three ingredients form the creamy backbone of the dressing, ensuring every bite is luscious.

Now, it's time to jazz things up. Add onion powder, garlic powder, dried dill weed, dried parsley flakes, garlic salt, salt, and black pepper. Each spice plays an essential role in creating the flavor profile that mimics the beloved Texas Roadhouse dish.

Add freshly squeezed lemon juice and white vinegar to the mixture. These ingredients bring brightness and balance to the creamy texture. If you decided to use Dijon mustard, now is the time to add it as well for an extra zing.

Grab a whisk and mix everything until it’s smooth and well-combined. Ensure there are no lumps. A consistent mix ensures that every part of the ranch dressing is flavorful.

This is the fun part! Use a clean spoon to taste the ranch. Adjust with additional salt, pepper, or even a pinch of cayenne for a kick, depending on your preference.

Cover the bowl with plastic wrap and let your Texas Roadhouse Ranch chill in the fridge for at least an hour. This step allows the flavors to meld together and intensify.
