Inspired by Mexico’s salsa de cacahuate, this version is slightly pared down in its use of chiles. Creamy, nutty and mildly spicy, it would also work well as a condiment for pork, chicken or as a topping for tacos or a grain bowl. It keeps well in the fridge for a week or more.

Ingredients

Directions

  1. Put a rimmed baking sheet on the top and bottom oven racks; preheat to 425 degrees F. Toss the potatoes with 1 tablespoon olive oil, 1 teaspoon cumin and 1/2 teaspoon salt. Transfer to the bottom hot baking sheet and roast, flipping once, until tender, 22 to 25 minutes.
  2. Meanwhile, heat a large cast-iron skillet over high heat. Add the chiles, tomato and garlic and cook until the chiles are pliable, 1 to 2 minutes. Remove the chiles to a bowl and add 1 cup very hot water. Continue charring the tomato and garlic, 5 more minutes; remove to a plate. Add the peanuts to the skillet and cook 30 seconds to 1 minute. Add to the tomato and garlic.
  3. Brush the steak with olive oil; season with salt and pepper. Add to the skillet and sear 2 minutes per side. Place on the top hot baking sheet and roast 5 to 6 minutes for medium-rare. Transfer to a cutting board and let rest 5 minutes.
  4. Peel the garlic. Drain the chiles, reserving the soaking water. Add the garlic and chiles to a blender along with the tomato, peanuts, lime juice, agave, oregano, 1/2 teaspoon salt, and the remaining 1 tablespoon olive oil and 1 teaspoon cumin. Puree, adding enough of the soaking liquid to make a smooth sauce.
  5. Slice the steak and drizzle with some sauce. Serve with the sweet potatoes, lime wedges and extra sauce on the side.
