Tacos de alambre are a Mexico City classic that can be a mix of almost any protein but almost always includes steak, onions, green peppers and melty cheese — and often bacon. It's served piled high on a plate like a mountain of goodness, with a side of warm tortillas and delicious salsas. While alambre means skewer, the skillet method has become standard, and here we're simplifying it even further with a sheet pan approach. Flank and skirt steak both work well so choose whatever is in your budget. In this recipe, bacon is placed in a cold oven and as the oven heats, it slowly melts the fat off of the bacon onto the sheet pan. Traditionally, tacos de alambre are the main event on their own, though there’s no reason you couldn’t serve them alongside refried beans and rice.

Preparation

  1. Step 1

    Line a sheet pan with aluminum foil. If using, spread the diced bacon evenly in the pan. Arrange a rack in the top third of your oven, place the sheet pan (with or without the bacon) in the cold oven and set the temperature to 425 degrees. 

  2. Step 2

    In a large bowl, combine the soy sauce, Worcestershire sauce and garlic. Juice the limes into the bowl and stir to combine. Dice the steak into ¾-inch pieces, add to the bowl and mix well to coat. Set aside to marinate.

  3. Step 3

    While the meat marinates, prep the remaining vegetables: Thinly slice the onion and mushrooms, trimming away any tough stem ends (reserve for stock if desired). Cut the pepper into ¾-inch dice. Add the vegetables to the bowl on top of the meat, but don’t mix them in. Sprinkle ½ teaspoon salt and 1 teaspoon pepper into the bowl.

  4. Step 4

    When the oven reaches temperature, about 15 minutes, carefully remove the hot sheet pan (the bacon fat will be hot), and pour the bacon and drippings into the bowl with the vegetables and stir to combine (the bacon won’t be crispy at this stage). If not using bacon, add 2 tablespoons oil to the bowl instead and toss to combine. Arrange the contents of the bowl in one layer on the hot sheet pan, place back in the oven, adjust the heat to 450 degrees and roast until meat is charred in spots and vegetables have begun to caramelize, about 20 minutes. 

  5. Step 5

    Toss the meat and vegetables in the sheet pan to coat with the juices, arrange in one layer again, and top with the cheese slices. Return to the oven until cheese is completely melted, 1 to 2 minutes.

  6. Step 6

    While the meat and vegetables roast, heat a cast-iron skillet over medium-high. Warm your tortillas in it, about 2 minutes per side, then transfer them to a clean dishtowel to stay warm. Keep the skillet on the heat over medium.

  7. Step 7

    To serve, scrape the cheesy meat and vegetable mixture directly into the hot skillet. Bring it to the table along with the warm tortillas and salsa so everyone can build their own tacos.

I tripled the garlic and used one red bell pepper and one poblano. We did not melt the cheese over the top, instead adding shredded cheese to individual servings. It was absolutely delicious! Next time I’ll double the marinade and use 2 bell peppers, 2 poblanos and double the mushrooms.

I understand the concept of placing meat and vegetables onto a preheated sheet pan, but I’m not at all sure that I want to remove a hot sheet pan full of bacon grease from the oven and transport, the pour it into the marinated meat and the vegetables. That sounds hazardous to me, but I am missing something here? Why not add meat and vegetables to the hot pan and gently mix them on it, then proceed with the recipe?

Used seitan instead of steak and omitted the bacon to make this vegetarian. DELICIOUS. Will make again.

I made this using vegan “steak” and olive oil, and it was absolutely delicious! I did find it too salty, however, and will either reduce or eliminate the salt completely in the future.

I made this per the recipe except I used pepper jack cheese instead of Munster. I found the meat to be overcooked and the veggies could have been cooked longer. Next time I'll cook the veggies for about 5-10 minutes before adding the meat. And I'll probably opt for sprinkling on queso fresco to taste when rolling up in the tortillas.

Really, really good. I was worried about lack of seasoning with only soy and Wsauce, but there was nothing to worry about. I did the bacon version and used 2 green bell peppers and 1 jalapeno as my store had no poblanos. Definitely double the marinade. Mushrooms are a great addition. No cheese, didn't need it. Excellent the next day in a rice bowl.
