Flattop Fajitas

Restaurant fajitas are a flattop cook that got famous for the sizzle. The sizzle is water hitting steel that is still hot enough to sear.

Most backyard fajitas skip the sear and go straight to the steam: wet marinade, crowded strips, a lid. You get gray beef and boiled peppers in a puddle of lime.

The plate can do both jobs. It just cannot do them in the same pile. See Steam vs sear.

The meat

Skirt steak is the classic. Flank works. Sirloin flap (bavette) works. Chicken thighs work. Chicken breast works if you accept that it dries out the second you look away.

1 to 1¼ pounds skirt steak for four people. Leave it whole, or in two pieces that still have a wide face. Do not cut it into strips first. Strips give you more edge and more leaked juice. A wide face gives you crust. You slice after.

Marinade (30 minutes to 4 hours, not overnight):

• Juice of 2 limes
• 2 tablespoons high-smoke oil
• 3 cloves garlic, smashed
• 1 teaspoon kosher salt
• 1 teaspoon ground cumin
• 1 teaspoon chili powder or a minced chipotle
• Black pepper

Overnight in lime turns the surface mushy. You want flavor on the meat, not ceviche. Pull it 20 minutes before the cook and pat it dry. A wet steak steams. The marinade already did its job in the bowl.

Chicken thighs: same marinade, 1¼ pounds boneless. They can go down as pieces. They need a little longer than steak.

The rest

Peppers and onion: 2 bell peppers (mixed colors if you want the photo), 1 large yellow onion. Cut into strips about ½ inch. This is the wet pile. It gets its own zone.

Tortillas: 8 flour, taco size. Corn if you insist. Warm, not crisp.

Finish: lime wedges, cilantro, a simple salsa or pickled jalapeños. Sour cream if that is the house. Cheese is optional and it is not the point.

Fat on the plate: refined avocado oil, a film.

Yield: 4 people, 2 tortillas each, leftover meat if you are honest about filling them.

Zones on the 36-inch

• Burners 1–2: high. Steak. You want 400–450°F. Water should skitter.
• Burner 3: medium. Peppers and onion. They will leak. That is fine here.
• Burner 4: off or very low. Tortillas, cooked meat resting, the dome you use only if a stubborn pepper needs a 20-second slump.

Do not put the steak and the vegetables in one heap. The vegetables will win, and they will win by boiling the beef.

Preheat 10–15 minutes.

The cook

1. Veg first, or steak first? Steak first if it is one piece. It needs the hottest steel and a quiet plate. Start the peppers on burner 3 while the steak rests. If you are doing chicken pieces, start the veg, then the chicken, so nothing sits raw in the cooler zone too long.

2. Oil a film on 1–2. Steak down. Do not move it. 2–3 minutes. You want a deep brown face, not grill marks you painted on. Flip. 2 minutes more for skirt that is about ½ inch thick. Skirt is done when it is browned and still pink in the middle. It will carry over.

3. Rest the steak on burner 4, off the heat. Tent loosely with foil if the wind is mean. Do not slice yet. Slicing now dumps the juice on the plate and you will cook it away.

4. Peppers and onion on burner 3. They should already be going. Spread them. Leave them 60–90 seconds before the first toss so some faces brown. Toss. If they pile up and look wet, you are steaming on purpose now, and that is allowed after you have color. A teaspoon of water and a 15-second dome on burner 3 will finish a hard onion. Do not dome the steak.

5. Slice the steak. Against the grain. Skirt grain runs the long way; cut across it into ¼-inch strips. If you cut with the grain you will be chewing until dessert.

6. Meat back on burner 3 for 20–30 seconds with the vegetables, just to coat. Not to cook again.

7. Tortillas on the fat that is left on burner 4 or the cool edge of 3. 15–20 seconds a side. Soft, warm, a few brown spots. A hard tortilla is a tostada.

8. Off the plate. Lime on the meat, not a minute earlier. Acid on the steel just makes steam and dulls the crust you already earned.

If it goes wrong

Gray strips, no crust. You cut first, or you did not dry the marinade, or you crowded steak onto burner 3 with the onions. Whole piece, dry, hot left side.

Peppers boiled, steak fine. You put them on the steak’s zone and they flooded it. Veg stays on 3.

Tough as a belt. You sliced with the grain, or you used a thick flank and cooked it like a well-done roast. Against the grain. Pull skirt while it is still pink.

Screaming smoke, acrid. Marinade sugar and garlic burned on a dirty plate. Scrape to the trough between the steak and the veg. Wipe a fresh film of oil.

Soggy tortillas. They sat on a wet pile of peppers. Warm them on a dry cool edge.

Chicken instead

Thighs on burners 1–2, medium-high rather than all-out high. 4–5 minutes a side until the thickest part is done. Rest, slice, toss with the veg. Breast is the same method and a tighter window. If you have to ask whether it is done, it is probably dry. An instant-read in the thick end should read 165°F. An instant-read thermometer is optional. Thighs forgive you. Breast does not.
