Spicy grilled chicken smothered in authentic Chimichurri Sauce is the perfect match for these creamy, dreamy, goat cheese mashed potatoes. You can grill, bake, or pan-fry chicken for this recipe. OR you can even use steak or portobello mushrooms. Everybody say, “Yum!!”

Chimichurri chicken served on a bed of goat cheese mashed potatoes. Smothered in Chimichurri Sauce.

One of my most favorite things is collecting recipes from all around the world. I moved around so much while I was growing up that I never really had a food culture of my own. Because of this, I got to adopt a lot of other people’s food cultures!

This Argentinian Chimichurri Sauce recipe is no exception. I haven’t yet travelled to Argentina or Uruguay, the home of chimichurri, I’ve only experienced the amazing recipes I have found over the years that claim to be traditional.

There are so many varieties of chimichurri out there. I even use a different version in my Steak Chimichurri Meal Prep Bowl — definitely check out this recipe! 📌 PIN IT NOW so you can try it out later!

What you’ll love about this recipe

First of all, what’s not to love about this recipe?! I seriously ate this meal every day for like a week and half because it’s that good.

  • Spicy, lip-smacking Chimichurri Sauce: I could eat this stuff on almost anything. Chimichurri is delicious on grilled meat and vegetables alike. Go crazy!
  • Creamy, tangy, mouthwatering: The goat cheese gives traditional mashed potatoes a tasty and slightly fancy twist.

Recipe Notes

I covered the Chimichurri Sauce recipe in its own post. Of course, I’ll include it here in the recipe card as well. Chimichurri is made of fresh herbs, oil, vinegar and garlic.

PRO-TIP: I once marinated my chicken in the chimichurri sauce before grilling. I probably won’t be doing that again! The oil in the chimichurri caused quite a flare-up on the grill.

It’s totally fine to marinate the chicken first if you are going to be pan-searing or baking the chicken. Your eyebrows will be safe.

Ingredients you’ll need

The Chimichurri Sauce and the mashed potatoes are the two main components of this recipe. The protein is totally up to you!

Chimichurri Chicken

  • Chicken: I just happened to have a bunch of chicken thighs in the freezer. Grilled chicken breasts are also fabulous. Alternatively, steak is amazing in this recipe. Roasted or grilled veggies are also a great option if you are doing a meatless Monday!

Chimichurri Sauce

  • Herbs, garlic, and peppers: Authentic chimichurri is made with parsley and dried oregano. But I love cilantro and green onions, too! Garlic is a definite must.
  • Chimichurri gets its heat from Serrano peppers, red if you can find them. If you can’t, a green Serrano pepper will work. Add red pepper flakes for color and heat.
  • Olive oil: Make sure that you get good olive oil. You’ll want to use extra virgin olive oil for this recipe because it has the most pronounced olive flavor, perfect for old-world cooking.
  • Vinegar: Red wine vinegar is traditionally used in this recipe. I have also used sherry vinegar, which is just a touch smoother.

Mashed Potatoes

These goat cheese mashed potatoes are a super flavor spin on the traditional version. They are also amazing with lamb burgers.

  • Russet potatoes: I most often use russet potatoes for mashed potatoes. They have a low starch content and yield fluffier mashed potatoes than other varieties of potatoes. Red potatoes are also delicious.
  • Goat cheese (soft) and goat butter: I like to use goat dairy products in this recipe. If you can find goat butter, I highly recommend it. But if not, regular unsalted butter is just fine!!
  • Broth: Use vegetable or chicken broth.
  • Garlic: Just one clove of garlic.

PRO TIP: Raw garlic has quite a bite. If you want to mellow out the flavor a bit, sauté the garlic in butter in the cooking pot before you add the boiled potatoes back in.

Step By Step Instructions

Heat up the grill so it’ll be ready to go when you are. Start by making the mashed potatoes. While the potatoes are boiling, whip up the Chimichurri Sauce. After you’ve made the Chimichurri Sauce, you can grill your chicken, and then dinner is served!

Mashed Potatoes

These mashed potatoes are a lot like garlic mashed potatoes, except the added goat cheese gives them a fantastic WOW flavor!

Step 1: Quarter the potatoes and place them in the water. Bring to a boil and then reduce the heat slightly. Boil until the potatoes are soft, about 15 minutes. Drain the water.

Peel the skins off the potatoes by giving the skins a little pinch, and return the peeled potatoes to the pot.

Step 2: Use a potato masher or a ricer to mash the cooked potatoes. (Food processors and blenders can make mashed potatoes super gluey, so I do this step by hand.)

Step 3: Add the finely chopped garlic. Alternatively, you can add the butter and garlic to the pan while you are draining the potatoes. Sautéing the garlic in butter softens the garlic flavor.

Step 5: Add the broth to the pot and then mix together to combine. These mashed potatoes do not require milk. While they do have goats’ milk in them, many people are less reactive to goat and sheep dairy than they are to cow dairy.

Add the broth and then mix together to combine.

Step 6: Re-mash and reheat (if needed).

Chimichurri Sauce

Chimichurri Sauce is a spicy oil-based condiment that is amazing on grilled meat and veggies.

Step 1: Gather all of your ingredients, chop the parsley, dice the Serrano pepper, and mince the garlic.

Step 2: Mix all of the ingredients together. If you want to make the Chimichurri Sauce ahead of time, you can omit the vinegar until right before you serve it. The vinegar will leach the color out of the herbs, so add the vinegar the same day you plan to serve the chimichurri.

Grill the Chicken

As I said before, I do NOT recommend marinating the chicken in the Chimichurri Sauce if you are going to grill it. The high oil content can end up flaring up on the grill. Very startling! You could also cook these chicken thighs on a grill pan.

Step 1: Season the chicken with salt and pepper. Cook the chicken on medium-high heat for about 12 minutes (6 minutes per side), or until the internal temperature reaches 145℉.
