Have you ever found yourself at a restaurant enjoying a plateful of delicious chicken fajitas and stopped to ask yourself the question: “What secret magic do they perform on this meat to make it so flavorful and scrumptious?” Well, wonder no more friends. I have discovered the secret and it lies within this Mexican chicken marinade recipe.

The Building Blocks of The Best Chicken Marinade

I am totally obsessed with this Netflix special (and cookbook) called Salt, Fat, Acid, Heat in which Chef Samin Nosrat discusses these 4 foundational elements of good cooking. And this Mexican chicken marinade has them all.

Salt – It tenderizes chicken by starting to break down the proteins, and draws moisture (and flavor) from the chicken marinade into the meat (so the marinade goodness permeates the whole chicken cut, not just the surface like a sauce that could drip or burn off.)
Fat – Oil accompanies the natural fat in the chicken to create that melt-in-your-mouth flavor, adding moisture and tenderness which are crucial (especially when grilling) to prevent the meat from drying out.
Acid – Citrus juice, like salt, tenderizes meat by helping to break down proteins and fats. It also adds a bite of zesty flavors to the overall chicken by replacing some of the natural meat juices.
Heat – Grilling uses some intensely high heat to cook your food. It sears the surface of your chicken, creating those nice grill marks and sealing in flavor and moisture. As fats/oils drip off, flame-ups char-broil the rest of the surface of your meat to flame-kissed perfection. All the while the ambient heat inside the grill completes cooking the inside of your meat. For those food scientists keeping score at home, that’s conduction, radiation, AND convection all performing a beautiful harmonious dance of thermodynamics, and the result is delicious!

Now let’s get to making this miracle mixture!

How To Make Mexican Chicken Marinade

Put all your ingredients (olive oil, lime juice, cilantro, garlic, oregano, chili powder, onion powder, black pepper, and salt) into your food processor or blender.
Pulse your marinade until everything is smoothly liquefied.
Pour the marinade into a food storage bag containing fresh (or defrosted) chicken cuts.
Refrigerate chicken for 2-24 hours before grilling.

Now that your chicken is marinating in the fridge, let’s move on to every dad’s favorite appliance; the grill.

Look Better Than You Really Are At Grilling

This past year, I dedicated myself to learning the art of grilling. I was determined to find easy recipes and methods that I could use that would finally give me some confidence in making grilled chicken. And I can tell you that my search has not been in vain. This Mexican chicken marinade makes the absolute best grilled chicken that I have ever tasted. Full stop.

I shared some grill advice in my last post for spicy chicken marinade (which is second only to this recipe in flavor), but these grilling tips warrant repeating, so here is a quick rundown.

Use boneless/skinless chicken thighs as your go-to cut for grilling. They taste good, they’re cheap, and they’re hard to overcook. Almost fool-proof. (Also perfect in my Air Fryer Chicken Thighs recipe…)
Skip needless meat prep steps. Don’t waste time poking a bunch of holes in it with a fork or preseasoning. I tested this marinade recipe all kinds of ways, and honestly couldn’t tell the difference to just marinating the chicken as-is, straight from the package.
Cook hot and fast. I consistently grill chicken thighs around 600 degrees Fahrenheit, and they only take about 6 minutes per side.
Flame-ups are a good thing. Don’t freak out unless something non-grilling related catches on fire.
Quit messing around! Lifting the grill lid, and moving your food around too much results in longer cook time and dry meat, because you’re letting heat and moisture escape. Plus, every time you move it, you risk your meat breaking apart and falling into a fiery grave.
Use a meat thermometer as your authority on when meat is cooked properly (not your eyeballs, or “feel”). Chicken is cooked properly when its internal temp is 165 degrees Fahrenheit.

Mexican Chicken That’s Better Than Restaurant Fajitas

Follow this recipe and my grilling tips, and you will be rewarded with a grilled chicken that is so tender, juicy, and flavorful that you might just stop ordering grilled chicken at restaurants. Because now, you can do it better yourself!

This Mexican chicken marinade recipe has such a good citrus and salty flavor balance that it makes a very versatile chicken. It can be a mean standalone grilled cilantro lime chicken, or the perfect chicken for Mason Jar Taco Salads. Either way, this is 100% the best chicken marinade that I’ve ever tried, and it’s sure to be a crowd pleaser for you too.

Crowd Pleasing Mexican Grilled Chicken Marinade

For my son’s birthday cookout, I doubled this chicken marinade recipe and was able to pack my grill with about 4 lbs. of marinated chicken thighs. We went through one of those giant bulk family sized chicken trays all at once without freezing anything (which checks off a bucket list item for me).

There was barely any room left in my grill to close the lid! …And folks LOVED it. Adults AND kids! Even a few that don’t normally like cilantro. I’m talking, 10 minutes later, those bad boys were G-O-N-E. Ga-hawn! Not bad.

So please, for the sake of all poultry, give this Mexican chicken marinade a try, and let me know what you think in the ratings/comments below! If this post doesn’t help you fill some bellies, and look like a grill master in the process, I promise that I’ll dance the funky chicken.
