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!

Your sauce is so green…and mine is white. Did I do something wrong?
Hi Heather! Tomatillos are green but they get lighter and lighter as they ripen, til they are nearly white. If you used more ripened tomatillos, that can affect the color of your sauce. I haven’t tried the dressing with nearly-white tomatillos but as long as your sauce tastes good, it doesn’t have to be green. 🙂
Just wondering if I could use packet of Italian dressing to sub the ranch? Went to the store to buy some ranch…and darn it, I forgot.
Hi Heron, I am not sure how Italian mix would come out in this recipe, it is a tomatillo ranch recipe so it would taste entirely different… you’re welcome to try it but I can’t vouch for the results! I’d love to hear though how it comes out!
Thanks for getting back, I stuck with your recipe and it is one of the best things the hubby and I have ever had. Thanks for sharing! 🙂
Making this now!!! I would have eaten the chicken raw with the marinade, but didn’t want to get sick!!
Ooh, looks good! Do you think adding a jalapeno to the party would throw off the flavor at all?
I also totally relate to eating Mexican a day or two after Thanksgiving. My husband and I seem to do that every year!
Oh no, this would be great with a little spicy kick! In fact, I think it would be amazing to use roasted jalapeños… just stick them in the oven for 5-10 minutes til they are slightly charred, peel off the skin, dice em up, and throw them in with the sauce! *Pro Tip: you can roast the jalapeños while the oven is preheating=bonus!
I did this , but roasted the tomatillos till they were charred, DELISH!!!
I enjoyed your background story to this recipe, I found it amusing and relatable..I can’t wait to try this!!
Are the tomatillos chopped and added to the marinade raw?
Yes!!
So you are marinating the chicken in the same sauce that you put on top at the end??
Part of the sauce is used as a marinade, then discarded as it states in the recipe. The remaining sauce which has not been used for marinating chicken is used to pour on top of the chicken. Hope you love it!
Can you warm up the sauce to put over the top of the chicken once its cooked? If so what would be the best way to do that
I could seriously have this every night of the week!
