Tender, juicy flank steak is topped with a bright and fresh pineapple chimichurri for a taco that's sweet, savory, smoky, and packed with flavor. These easy steak tacos are perfect for weeknight dinners or summer cookouts.
Pat the flank steak dry with paper towels. Rub with olive oil, then season evenly with chili powder, cumin, smoked paprika, salt, and black pepper.
Char the Pineapple
Heat a large skillet over medium-high heat. Add the pineapple chunks and cook for 2–3 minutes per side until lightly caramelized and charred. Remove from the pan and let cool slightly.
Make the Pineapple Chimichurri
Finely chop the charred pineapple. In a medium bowl, combine the pineapple, parsley, cilantro, olive oil, lime juice, garlic, salt, and red pepper flakes if using. Stir well and set aside.
Cook the Steak
Using the same hot skillet or a grill pan, cook the steak for 3–5 minutes per side, depending on thickness and desired doneness.
Remove the steak from the heat and let it rest for 5–10 minutes before slicing thinly against the grain.
Warm the Tortillas
Warm the tortillas in a dry skillet for 30 seconds per side or wrap them in foil and heat in a 300°F oven for about 10 minutes.
Assemble the Tacos
Fill each tortilla with sliced steak. Top generously with pineapple chimichurri, red onion, and crumbled feta cheese. Garnish with additional herbs and serve with lime wedges.
Notes
Slice the steak against the grain for the most tender bites.
Charring the pineapple adds sweetness and smoky flavor.
The chimichurri can be made several hours ahead and refrigerated.
Warm tortillas are less likely to tear and have better flavor.
