How To Make Authentic Guacamole

My first experience with guacamole was the one in The Barefoot Contessa book, a flavorful guacamole that has the requisite avocados, red onion and lemon juice, but departs from the norm with fresh garlic and a few hits of Tabasco. Up until last weekend, if I were sent to the store to shop for guacamole ingredients, I probably would’ve stuck to The Barefoot Contessa formula. But then my friend Mark entered the picture.

We were upstate last weekend, at our friend Cary’s barn (readers of my newsletter would’ve known that!) and Mark had done the food shopping. And while shopping, Mark had bought himself the ingredients to make guacamole.

What’s important to know is that Mark is from New Mexico. Once I tried to cook Mark an authentic New Mexican green chile stew and it didn’t go well (see here). He knows his stuff when it comes to Mexican (or New Mexican) food. (He also wrote “Black Swan,” but that’s neither here nor there.)

So anyway, in the kitchen of Cary’s barn, I asked Mark if he wanted some help making the guacamole:


“Sure,” said Mark.

I began chopping a red onion while Mark tackled a lemon. At some point I asked where the garlic was.

“Garlic?” Mark asked with a furrowed brow.

Turns out, authentic guacamole doesn’t have garlic. This is when Mark educated me on what goes into a proper guacamole (you should memorize this): avocados, lemon juice, red onion, a tomato, salt, pepper and two ingredients The Barefoot Contessa doesn’t have in her recipe but which Mark considers essential…. cilantro and a whole jalapeño.

That’s really all there is to it. Mash with a fork (or, if you have a large marble mortar and pestle like I do now, it’s great in there too), taste for lemon juice and salt and serve.


I’ve never seen a guacamole go faster. And this was so delicious that upon returning from upstate, I recreated Mark’s guacamole at home to serve on a hot, humid night with cold beer. The only additional tip I’ll offer is to buy Haas avocados that are starting to brown; those will be much softer (and easier to work with) than anything that’s bright green.

So thank you, Mark, for educating me in the ways of authentic guacamole. Garlic, you are banished from my guacamole forevermore.


Since writing this post, Mark has written me to address one of the more controversial elements of his recipe–the lemons instead limes. “I noticed some people were asking about lime vs. lemon, and you can really go either way. I prefer lemon just because I’m not crazy about the metallic quality of limes (so I even use lemon in margaritas, as does my favorite NM restaurant), but it’s a personal preference and limes are technically more traditional.” There you have it.

Mark’s Authentic Guacamole

based on a recipe by Mark Heyman

Serves 4 to 6

4 to 6 ripe Haas avocados (they should have mostly brown skin)

1 small red onion, chopped

1 small tomato, diced

1 large jalapeño, stemmed and seeded and finely diced

1/4 cup chopped cilantro, plus more for garnish

Juice from 1 lemon, plus more as necessary

Salt, to taste

Tortilla chips (for serving)

1. Slice your avocados in half vertically, circling your knife around the pit. Separate the two halves and then smack your knife into the hard pit (this is the best way to remove it.) Use a paper towel or a dish towel to yank it off your knife (it’s a good way to cut yourself, otherwise.) Use a spoon to cleanly scoop the avocado flesh into a large bowl. Repeat with the rest of the avocados.

2. Add the rest of the ingredients to the bowl and begin to mash it all together with a fork. The most essential part is that you break down the avocados into a pulp, working the jalapeno, onion and cilantro into the mass as you do so. You’ll know your done when there are no hard bits of avocado remaining.

3. Taste and adjust for salt and lemon juice. When it’s delicious, sprinkle some more cilantro to garnish and serve with a big bag of sturdy, high-quality tortilla chips for scooping. Goes great with beer.

  1. Some would say authentic guacamole has no tomatoes. We use the Two Hot Tamales version–Haas avocados, red onion, jalapeños, lime juice, cilantro, a bit of salt (taste first as the line juice takes it almost there), and pepper.

    Love your site!

  2. Plus it’s not authentic. In Mexico guacamole is just avocado paste and salt. If tomatoes or other vegetables are added, it’s guacamole salad.

  3. I hate tomatoes in guacamole. So do most Mexicans. If you add tomatoes in Mexico, it’s called ‘guacamole salad’, not guacamole.

    Ina detests cilantro, which is why it’s omitted from her recipe. It’s a must for me, however! Thanks for this recipe.

Let's dish!
