Music is a big thing for me. For my husband though, the radio is more of a “background noise” thing. I love country, and he’ll throw on the pop station when he gets in the car. This could have been a big deal breaker in the beginning, but I was willing to let it go because of one very important thing we have in common: our deep adoration for Mexican food. I loooooove Mexican food. LOVE it passionately. When I was a kid, I ate so many burritos my mother would say “you’re going to turn into a burrito!” and oh how I’d wished she were right.

Of course, I’m in the mood for Mexican food every meal of every day ever, but my husband made a really interesting point this week. He mentioned that after Thanksgiving he always has to have a spicy Mexican meal. Although I’d never be opposed to it, I asked him why. He said that something about the “bland” Thanksgiving flavors makes him crave something with a real good kick afterwards. I thought about it for a minute, and then realized I totally agree! Now, I personally wouldn’t say Thanksgiving flavors are “bland” but I get what he’s trying to say.
I fixed up this super easy Tomatillo Ranch Chicken and it really hit the spot! The creamy ranch with big tomatillo and cilantro flavors were perfect. The chicken was juicy and flavorful after marinating it in the dressing, cooking it in the dressing, and loading plenty of extra on top. We loved the creamy dressing and my husband mentioned afterwards that he’d like to use the leftovers on a salad. This yummy chicken dish is easy to throw together and perfect for a simple and delicious weeknight meal!

Hi Tiffany,
It’s me again. I just wanted to say that this recipe was a HUGE HIT!! Will be a regular on our menu. Hubby LOVED it. Thank you so much for sharing this simple yet delicious dish. I will be trying out your chicken recipes as well.
Muchas gracias!!
Made your recipe! Awesome sauce! Literally! We are going to use it on salmon tomorrow. Thanks
P.S. We nuked the sauce for the chicken in the microwave for about 15 seconds, so we wouldn’t have to put cold sauce on the warm dish.
It’s seriously addictive and goes with everything! Sometimes I just pour it over rice!
Outstanding! Even with the subs I had to make! Used boneless chicken thighs, reconstituted buttermilk and a small can of salsa verde instead of tomatilloes. (Obviously I didn’t want to make a trip to the grocery store!) The sauce was not as thick as it probably should’ve been, but it was sooooo good! The family labeled it “gourmet”. Thanks for sharing the recipe!
Hey! I was curious…do the tomatillos have to be blended or just diced and added to the rest of the ingredients? Cant wait to try this out!
Hi Samantha! I’ve never tried this recipe without blending the tomatillos, when they are pureed the flavor is distributed evenly throughout the sauce – so I can’t vouch for any results without blending them! Sorry, I hope this helps!
Tiffany, this was absolutely delicious. My husband and I too are big fans of Mexican food and especially cilantro. This was fantastic. My husband said he could just eat the sauce over Jasmine rice and it would still be great.
Thank you for sharing! I will try many more of your recipes!!
It calls for 2 1/2 teaspoons of garlic, garlic powder or garlic salt??
Yes! Very curious about this 🙂 can you please clarify? I just want to make this meal as great as possible.
Hi Tiffany,
I am making this right now. Had the chicken marinating overnight and it’s in the oven as I type this so I can’t wait for dinner, lol. The sauce tastes AMAZING even as a salad dressing and a roasted jalapeno would take it up a notch but here’s my question, how did you warm up the extra sauce to put on top of the chicken? Chicken is warm and sauce was in the fridge so it’s cold. Just wondering.
Thank you!!!
Hi Christine! Isn’t that sauce delish?? I could drink it straight! For the extra sauce to pour on top, you can heat it in the microwave or over the stove in a small sauce pan. 🙂
Thank you Tiffany! That’s what I thought but just wanted to be sure. Have a great day!
This was INCREDIBLE! Thanks so much! 🙂
Hi Jessica! I’m so happy to hear you loved this recipe! It’s one of mine and my husband’s favorites 🙂 🙂
I absolutely LOVE this chicken! I’ve made it a couple times now and I double the marinade because it’s so thick that it makes an awesome salad dressing too. Yum!
I read all of the directions so I have no silly questions, I just wanted to tell you how much my family loved this recipe. It will surely be a regular in our house! We paired it with a black bean and avocado salad – delish! Thank you for sharing!
Ha! Oh that made my day. 🙂 Thanks so much for taking a minute to comment and let me know how much your family loved this dish – it’s one of our favorites and I am so happy to hear that you enjoyed it too! 🙂
This recipe looked awesome, but I couldn’t make it exactly as written due to food sensitivities. I subbed 2 avocados and 8 oz of plain greek yogurt for the buttermilk and mayo. It was delicious! Bonus, the avocado makes it bright green! Thanks for the recipe!
Is there any way that the cilantro could be left out? I like the idea of using roasted jalapenos and wondered if this would help substitute.
Hi Amy, I’m not sure how this sauce would turn out without cilantro, as cilantro has a potent flavor and adds a lot to this dish. I am a huge fan of roasting jalapeños though. You could definitely give this dish a try with roasted jalapeños and no cilantro, but I can’t guarantee any results. It definitely won’t taste like my dish, but it could still turn out to be quite tasty! Let me know, I would love to hear how it goes if you do try it! 🙂
