Copycat Cafe Rio Creamy Tomatillo Dressing (Better Than the Restaurant!)

The first time I tasted Cafe Rio’s tomatillo dressing, I was at their restaurant with friends who insisted I try their signature salad. One bite of that crisp romaine lettuce drizzled with creamy, tangy, slightly spicy dressing, and I was converted. What was this magical green sauce that somehow managed to be simultaneously creamy, zesty, herbaceous, and just a little bit spicy?

For weeks afterward, I found myself craving that distinctive flavor. I’d even make special trips to Cafe Rio just for a side of the dressing. That’s when I knew I needed to create my own version at home. After several attempts and tweaks, I finally perfected this copycat recipe that captures all the complexity of the original—the brightness of fresh cilantro and lime, the subtle tanginess of tomatillos, and that perfect hint of heat from jalapeño.

Tomatillo Dressing Ingredients 

• Jalapeño pepper – Contributes the perfect level of heat that builds gradually without overwhelming
• Buttermilk – Provides tangy creaminess and helps thin the dressing to the perfect consistency
• Mayonnaise – Creates a rich, smooth base that balances the acidity and heat of other ingredients
• Dry ranch dressing mix – Contributes a complex blend of herbs and seasonings that forms the foundation of the flavor profile
• Tomatillos – Add distinctive bright, citrusy tartness that defines this dressing’s unique character
• Garlic – Brings pungent depth that enhances all the other flavors
• Fresh cilantro – Delivers the signature herbaceous, slightly citrusy notes essential to authentic Cafe Rio flavor
• Lime juice – Adds vibrant acidity that brightens the entire dressing

Understanding Tomatillos: The Star Ingredient

Tomatillos are the unsung heroes of Mexican cuisine and the key ingredient that makes this dressing special. Often mistaken for green tomatoes, these small, firm fruits encased in a papery husk are actually related to gooseberries and bring a unique tart-sweet flavor that’s incomparable.

Selecting Perfect Tomatillos:

• Look for firm, bright green fruits that fill their husks completely
• The husk should be light tan or green, fresh-looking, and not dried out
• Smaller tomatillos (about golf ball size) tend to be sweeter and more flavorful than larger ones
• Avoid fruits with yellowing skin, as they will be overripe and less tart

Preparing Tomatillos:

1. Remove the papery husks completely
2. Rinse under warm water to remove the sticky residue on the skin
3. No need to peel—the skin is edible and contains much of the flavor
4. A quick rough chop is all that’s needed as they’ll be puréed in the dressing

How to Make It Cafe Rio Tomatillo Ranch Dressing

To prepare Cafe Rio’s Tomatillo Dressing: 

1. Remove the husks from the tomatillos and roughly chop. 
2. When you cut off the stem of the jalapeno pepper, it splits open horizontally. Use a knife to trim off the ribs of the pepper and remove the seeds. Leave the ribs and seeds alone if you want the dressing extra spicy. 
3. Add the buttermilk, mayonnaise, and a packet of dry ranch dressing to the bowl of a food processor or the jar of a blend. 
4. Process for about 30 seconds.
5. Add the rest of the ingredients and continue to process until the dressing is smooth and creamy. Depending on the power of the equipment you are using, it may take a minute or two. Be patient and ensure no large chunks remain in the dressing. 
6. Use a rubber spatula to scrape the dressing into a container and chill for at least an hour before serving.
