The beef cut of choice for California barbecue and grilling, tri-tip steak (also called Newport, Santa Maria, or triangle steak) comes from the lean bottom sirloin. Here it’s sliced and seasoned with rosemary, chiles, garlic, and cumin in a tender filling for tacos. This recipe first appeared in our December 2012 issue along with Georgia Freedman’s story California Eternal.
- 2 lb. whole tri-tip steak
- Kosher salt and freshly ground black pepper, to taste
- 1⁄3 cup olive oil
- 1⁄4 cup rosemary leaves
- 6 cloves garlic, mashed into a paste
- 2 large poblano chiles
- 1 large yellow onion, roughly chopped
- 1 tsp. dark chile powder
- 1 tsp. ground cumin
- Warm corn tortillas, for serving
- Tomato salsa, for serving (optional)
- Season steak with salt and pepper, and rub with 3 tbsp. olive oil, rosemary, and garlic; wrap tightly in plastic wrap, and refrigerate at least 6 hours or up to overnight.
- Heat broiler to high. Place chiles on a foil-lined baking sheet, and broil, turning as needed, until blackened all over, about 20 minutes. Transfer to a bowl, cover with plastic wrap, and let sit until cooled, about 30 minutes. Remove stems, skins, and seeds; roughly chop, and set aside.
- Build a medium-hot fire in a charcoal grill, or heat a gas grill to medium. (Alternatively, heat a cast-iron grill pan over medium-high heat.) Remove steak from marinade, and transfer to grill; cook fat-side down, flipping once, until charred and cooked to desired done-ness, about 50 minutes for medium. Transfer steak to a cutting board, and let rest for 15 minutes.
- Meanwhile, heat remaining oil in a 12″ skillet over medium-high heat; add onion, and cook, stirring, until soft, about 10 minutes. Stir in reserved chiles along with chile powder, cumin, and salt and pepper; remove from the heat.
- Thinly slice meat against the grain, and then roughly chop; combine with onion and chile mixture in a serving bowl, and serve with tortillas and salsa, if you like.
