Here’s what you’ll need to make this flavorful skillet dinner:

Flank steak – A lean, tender cut that sears beautifully in a cast iron pan.

Corn on the cob – Boiled or grilled, it adds sweetness and texture.

Fresh baby spinach – The base of our bold green sauce.

Feta cheese – Creamy, tangy crumbles that melt just slightly into the warm steak.

Fresh herbs – Chopped cilantro or parsley to finish everything off.

Pro Tips Before You Start

Use a cast iron skillet – It gives the steak a perfect crust and caramelizes the corn beautifully.

Slice against the grain – This keeps the steak tender.

Boil or grill your corn – Either method works; grilling adds extra smoky flavor.

Blend spinach sauce well – Let it run until silky smooth for best texture.

Prep ahead – You can make the spinach sauce a day in advance.

How to Make Spinach Steak with Corn and Feta

Step 1: Prepare the Corn

Boil 3 ears of corn for 5–10 minutes until just tender, then drain.

Once cool, stand each ear on a cutting board and slice off the kernels. Set aside.

Step 2: Make the Spinach Sauce

In a food processor, blend spinach, garlic, olive oil, balsamic vinegar, cumin, chili powder, and salt until completely smooth (about 3–5 minutes).

Scrape into a bowl and set aside.

Step 3: Season and Sear the Steak

Rub the flank steak with chili powder, salt, pepper, and 1 tablespoon of olive oil.

Heat a large cast iron skillet over medium heat for 3 minutes, then add another tablespoon of oil.

Sear the steak for 5 minutes per side (medium heat), adjusting to your desired doneness.

Remove and let rest before slicing against the grain into 1-inch strips.

Step 4: Finish in the Skillet

Add the final tablespoon of olive oil to the same skillet.

Return the sliced steak and its juices to the pan to warm through.

Push the steak to one side, add corn to the other, and gently reheat.

Step 5: Assemble and Garnish

Divide steak and corn between plates.

Drizzle steak with spinach sauce, sprinkle everything with feta cheese, and top with fresh cilantro or parsley.

What to Serve It With

Garlic bread – Perfect for soaking up extra sauce.

Mashed potatoes – Adds creaminess to balance the tangy feta.

Lemon rice or herbed couscous – For a Mediterranean flair.

Grilled veggies – Try zucchini, eggplant, or asparagus.

Variations / Substitutions

Swap the steak – Try sirloin or even grilled chicken thighs.

Use frozen corn – If fresh corn isn’t in season.

Make it dairy-free – Omit the feta or use a vegan feta alternative.

Add red pepper flakes – For extra heat in the spinach sauce.

Try goat cheese – As a softer, tangier alternative to feta.

Storage & Leftovers

Refrigerate – Store leftovers in an airtight container for up to 3 days.

Reheat – Warm in a skillet over low heat with a splash of water or oil.

Spinach sauce – Keeps in the fridge for up to 4 days and is great on other proteins or veggies.

Not freezer-friendly – This dish is best enjoyed fresh.

FAQs

How do I know when flank steak is cooked perfectly?
