Charred Zucchini and Corn with Sesame Salsa Macha
Zucchini half-moons and sweet corn blistered hard in a dry skillet with red onion and pinto beans, spooned over with a rust-colored sesame and garlic salsa macha sharpened with chipotle, vinegar, and lime.
Why You'll Love This Recipe
I started making salsa macha because I wanted something with the depth of a long-cooked sauce that I could have ready in five minutes, and this version, built on sesame seeds and sliced garlic toasted slowly in olive oil, does exactly that. It is one of the few things in my kitchen that improves everything it touches. Over a skillet of vegetables it stops being a condiment and becomes the reason the plate works, because the seeds stay crunchy in the oil and every spoonful lands with texture as well as heat. I keep a jar of it in the refrigerator most weeks and this is the lunch it was made for.
The eating is a study in contrasts. Zucchini charred properly goes silky in the middle with blackened, almost bitter edges, and the corn beside it stays sweet and snappy, popping between your teeth. Pinto beans soften into the hot pan and pick up the smoke. Then the salsa goes over, warm and loose, and the sesame seeds catch in the folds of the zucchini so you get a crunch in bites you did not expect. Lime and a fistful of cilantro at the very end keep the whole thing from going heavy, and the chipotle sits underneath as a slow warmth rather than a sharp burn.
This is a midweek lunch, made in one pan in under half an hour, and it is at its best in late summer when zucchini is cheap and the corn is worth cutting off the cob. Out of season I use frozen corn and dry it well, and nobody has ever noticed. It reheats gracefully and eats just as happily at room temperature, so I make the full four servings even when I am cooking for myself and carry the rest to work. If I have avocado on the counter, half of one sliced over the top finishes it.
Ingredients
- 1 1/2 lb zucchini (about 4 medium), cut into 3/4-inch half-moons
- 3 cups corn kernels, cut from 4 ears or thawed from frozen and patted dry
- 1 cup canned no-salt-added pinto beans (about half a 15 oz can), drained and rinsed
- 1 red onion, halved through the root and sliced 1/2 inch thick
- 1/3 cup sesame seeds
- 4 tbsp olive oil, divided
- 4 cloves garlic, sliced paper thin
- 2 tsp chipotle powder
- 1 tsp dried Mexican oregano, crumbled between your fingers
- 1 tbsp apple cider vinegar
- 1 jalapeno, sliced into thin rings
- 2 tbsp lime juice, plus wedges for the table
- 1/2 cup cilantro leaves and thin stems, roughly chopped
- 1/2 tsp fine sea salt
Instructions
- Cut the vegetables for a hot pan: Trim the zucchini and cut it into half-moons a good three quarters of an inch thick, since thin slices collapse before they char. Spread them on a towel and pat them dry, and do the same with the corn if it came from a bag. Slice the onion into thick half rings and keep the layers together so they do not scatter.
- Make the salsa macha: Put 3 tbsp of the olive oil, the sliced garlic, and the sesame seeds into a small cold skillet and set it over medium-low heat. Let it come up slowly, swirling now and then, for four to five minutes, until the seeds are the color of straw and the garlic is pale gold at the edges. Pull it off the burner immediately, since it goes from toasted to burnt in about twenty seconds, and stir in the chipotle powder, the oregano, and the vinegar. It will hiss and turn rust colored. Set it aside.
- Char the zucchini: Heat your widest cast iron or steel skillet over medium-high until a drop of water skitters, then add the remaining tablespoon of oil and lay the zucchini in a single layer, cut faces down. Leave it completely alone for four minutes, until the undersides are dark brown to black in places, then turn the pieces and give them two minutes more. Move them to a platter.
- Blister the corn and onion: Add the corn and the onion to the same dry pan and press them flat. Leave them for two to three minutes without stirring so the kernels catch and pop, then toss once and cook another two minutes, until you can smell the corn browning and the onion has softened but still has some spring to it.
- Bring it together: Stir in the pinto beans and the salt and warm them through for a minute, then return the zucchini and any juices on the platter and toss gently, just enough to combine without breaking the vegetables. Take the pan off the heat, add the lime juice, and pile the jalapeno rings and cilantro on top. Spoon the salsa macha over the whole thing at the table, stirring the jar first so you get oil and seeds together.
Variations
- Add avocado: Slice half an avocado over each plate just before the salsa goes on. The cool fat plays against the smoke and makes the lunch feel more substantial.
- Charred cabbage: Swap half the zucchini for wedges of green cabbage seared cut side down until the outer leaves blacken and the core turns sweet.
- Crumbled tofu: Brown a cup of crumbled firm tofu in the pan before the zucchini goes in, and fold it back through at the end for a firmer, chewier plate.
- Herb swap: Trade the cilantro for torn mint and a handful of sliced scallion tops, which sends the whole dish somewhere brighter and greener.
- Warm tortillas: Pile the vegetables into charred corn tortillas with the salsa spooned inside and eat it with your hands.
Storage & Leftovers
Leftovers keep for three days in a sealed container in the refrigerator. Store the salsa macha in its own small jar rather than mixed through, because the seeds soften once they sit in the vegetable juices and the crunch is the whole point. The jar of salsa itself keeps for a month in the cold and is worth making double.
Reheat the vegetables in a dry skillet over medium-high for three or four minutes, spread flat and left alone for the first two so the charred edges come back. The microwave will heat them through, but the zucchini goes slack and the corn loses its snap. A fresh squeeze of lime after reheating wakes the whole plate up again.
This one does not freeze well. Zucchini is mostly water and it thaws into something soft and weeping, which no amount of pan time will fix. The salsa macha, on the other hand, freezes for three months in a small jar and thaws on the counter in an hour, so make a big batch of that and keep the vegetables fresh.
Notes & Tips
- Start the salsa in a cold pan: Sesame seeds dropped into hot oil scorch on the outside before the inside toasts. A cold start and a low flame gives you even color and the nutty smell you are listening for.
- Pull the salsa early: Residual heat keeps cooking the seeds in the oil after the pan leaves the burner, so take it off when the seeds are one shade paler than you want them.
- Cut the zucchini thick: Thin coins turn to mush before they take on any color. Three quarters of an inch gives you a piece that can sit in a hot pan for four minutes and still have a creamy middle.
- Dry everything: Wet vegetables steam. A minute with a kitchen towel over the zucchini and corn is the difference between a browned plate and a gray one.
- Use the widest pan you own: Everything here needs contact with the metal to char. Two batches in a small skillet beat one crowded heap every time.
- Add the lime off the heat: Acid added to a screaming pan evaporates and turns dull. Off the burner it stays sharp and lifts the smoke of the chipotle.
Nutrition & Mindful Eating
- Zucchini, corn, pinto beans, and sesame each pull in a different direction here. The zucchini brings bulk and water, the corn brings sweetness and a little whole-food starch, the beans bring fiber and plant protein, and the sesame oil spooned over the top brings the fat that makes a plate of vegetables eat like an actual meal.
- Sesame seeds are the quiet workhorse of this dish. A third of a cup toasted in oil is where the crunch comes from, and sesame carries more calcium than most people expect from a seed, along with the unsaturated fat that makes the salsa cling to everything.
- Zucchini charred hard tastes almost nothing like zucchini boiled. The heat drives off water and concentrates what is left, and the flesh holds vitamin C and a soft fiber that suits people whose digestion is easily irritated.
- Pinto beans go in as a scatter rather than a base, and a cup of them across the pan adds fiber and folate along with a starchy softness that catches the salsa in a way the vegetables cannot.
- Chipotle, oregano, cider vinegar, and lime are doing all the seasoning work. Smoked chile gives warmth without sharpness, the vinegar hits the hot oil and blooms, and the lime goes on last so it stays bright rather than cooking away.
- As you eat, look for the blackest edges of zucchini and the sesame seeds caught in the folds, and let the crunch slow you down enough to notice when the plate has actually done its job.
Frequently Asked Questions
My zucchini went soggy rather than charred. What happened?
Almost always a crowded pan or wet slices. A pound and a half of zucchini needs a twelve-inch skillet, and if yours is smaller, char it in two batches and combine at the end. Cut the pieces thick, dry them on a towel, and give them a genuinely hot pan and four undisturbed minutes.
Is salsa macha supposed to be this spicy?
It is meant to be warm rather than punishing, and chipotle brings smoke as much as heat. Two teaspoons gives a gentle background warmth across four servings. If you want more, add a quarter teaspoon of cayenne with the chipotle, and if you want less, drop to one teaspoon and add the jalapeno rings to taste at the table.
Can I use frozen corn?
Yes, and I do for most of the year. Thaw it first and dry it thoroughly on a towel, because ice crystals turn into steam and steam is the enemy of browning. Frozen kernels are picked and frozen quickly, so they are often sweeter in February than anything sitting in the produce aisle.
What else can I put the salsa on?
Almost anything. It is very good over roasted cauliflower, stirred into a pot of beans, spooned over a fried egg, or dripped onto sliced avocado with a little lime. Once you have a jar you will find yourself reaching for it several times a week.
