Description

Juicy pan-seared flank steak served with sweet corn, tangy feta, and a creamy spinach sauce that’s mildly herby and reminiscent of chimichurri—an easy and flavorful one-pan summer dinner.


Ingredients

  • 3 ears corn on the cob (or roughly 2 cups cooked kernels)
  • 5 oz fresh baby spinach
  • 1 large clove garlic
  • 3 Tbsp olive oil (for sauce)
  • 1 Tbsp balsamic vinegar
  • 1/2 tsp cumin
  • 1 tsp chili powder (for sauce)
  • 1/4 tsp salt (for sauce)
  • 1 lb flank steak
  • 1 tsp chili powder (for steak)
  • 1/2 tsp salt (for steak)
  • Freshly ground black pepper, to taste
  • 3 Tbsp olive oil, divided (for steak and pan)
  • 4 oz crumbled feta cheese
  • Chopped fresh cilantro or parsley (for garnish)

Instructions

  1. Boil or grill the corn until tender or charred, about 5–10 minutes. Let cool, then slice off the kernels.
  2. In a food processor, blend spinach, garlic, 3 Tbsp olive oil, balsamic vinegar, cumin, 1 tsp chili powder, and 1/4 tsp salt until smooth, about 3–5 minutes.
  3. Rub flank steak with chili powder, salt, pepper, and 1 Tbsp olive oil. Heat a cast-iron skillet over medium heat for 3 minutes, then sear steak for about 5 minutes per side (130°F for medium-rare or 145°F for medium).
  4. Remove steak, let rest, then slice against the grain. Add remaining olive oil to the pan and briefly reheat steak slices with the corn.
  5. Plate the steak and corn, drizzle with spinach sauce, and top with crumbled feta and herbs.

Notes

  • Use frozen or canned corn if fresh isn’t available.
  • Grill steak instead of pan-searing for a smoky flavor.
  • Prepare the sauce and corn up to two days ahead for easier meal prep.
  • Swap parsley for cilantro in the garnish for a different flavor.
  • Use a blender if no food processor is available.
