Cast-Iron Ribeye with Chimichurri

30 MinutesGluten-FreeHigh-ProteinLow-Carb

A cast-iron sear gives you a steakhouse crust at home, and the chimichurri — parsley, garlic, vinegar, good olive oil — does the rest. This is the new pyramid on one plate: protein at the center, healthy fats doing the flavor work, ready in 30 honest minutes.

Recipe Highlights

  • 46 grams of protein per serving. One pan, one steak, and the pyramid’s top tier is done for the day.
  • Ready in 30 honest minutes. Ten of those are the steak resting — hands-off.
  • Naturally low-carb and gluten-free. No modifications needed.
  • The chimichurri does double duty. Leftovers dress grilled chicken, eggs, and roasted vegetables all week.

What To Gather

  • Ribeye: Look for 1.5-inch thickness so the crust forms before the center overshoots. A NY strip or sirloin works — reduce sear time by a minute per side.
  • Flat-leaf parsley: The backbone of the chimichurri. Cilantro-parsley half-and-half is a great variation.
  • Red wine vinegar: Brightens the sauce. Sherry vinegar or lemon juice in a pinch.
  • Extra-virgin olive oil: Use one you’d eat with bread — it’s half the sauce.
  • Garlic, coarse salt, red pepper flakes: The non-negotiables.

Tip · Our Special Step

Rest the chimichurri, not just the steak. Ten minutes lets the garlic mellow into the oil instead of biting through it — the difference between a good sauce and the one people ask about.

How To Get the Crust Right

Cast iron wants two things: a dry steak and real heat. Pat the ribeye dry, salt it while the pan preheats, and don’t move it once it lands. For more technique guides, see the Field Guide.

What To Serve It With

Keep the plate on-pyramid with the Rainbow Chickpea Power Bowl greens and dressing, or roast an extra pan of vegetables alongside the Lemon-Herb Chicken’s rainbow mix. More ideas in the 30-minute dinner collection.

Storing Leftovers

Sliced steak keeps 3 days refrigerated in an airtight container; reheat gently or serve cold over greens. Chimichurri keeps 5 days — the oil may solidify in the fridge, so let it stand 15 minutes before using.
