Perfect Delmonico Steak in Cast Iron: A Simple Guide

Dreaming of a steak that’s incredibly juicy and bursting with flavor, just like your favorite steakhouse? Grab your trusty cast iron skillet because we’re about to unlock the magic of cooking a Delmonico steak! This guide will make it super easy for you to create a culinary masterpiece right in your own kitchen.

Meet the Delmonico: Your Steakhouse Star

The name “Delmonico” carries a legacy from the famous Delmonico’s Restaurant in New York. While its exact cut has evolved, today a true Delmonico is typically a thick-cut, boneless ribeye. What makes it special? Its incredible marbling – those lovely streaks of fat that melt into the meat as it cooks, guaranteeing unmatched tenderness and a rich, buttery flavor. When shopping, look for a quality boneless ribeye for that authentic experience.

Why Cast Iron is Your Steak’s Best Friend

For a perfect steak, cast iron is simply unbeatable:

  • Even Heat: It heats consistently and holds high temperatures beautifully.
  • Amazing Sear: This sustained heat creates a mouth-watering, caramelized crust.
  • Versatility: Seamlessly move from stovetop to oven if your recipe calls for it.

Prep for Perfection: Getting Your Delmonico Ready

A little preparation ensures a phenomenal result:

1. Choose Wisely

Select a boneless ribeye that’s 1.5 to 2 inches thick with good, even marbling. Thicker steaks are easier to cook to perfection without drying out.

2. Bring to Room Temperature

Let your steak sit out for 30-60 minutes before cooking. This promotes even cooking from edge to center.

3. Pat it Bone Dry

Crucial for a great crust! Use paper towels to remove all surface moisture. A dry steak sears; a wet steak steams.

4. Season Generously

Liberally season both sides and edges with coarse salt (like kosher or sea salt) and freshly ground black pepper. Don’t be shy – this thick cut can handle it!

Sizzle Time! Your Step-by-Step Cooking Guide

Let’s get cooking!

Step 1: Super-Hot Skillet

Place your cast iron skillet over high heat. Allow it to preheat for 5-10 minutes until it’s smoking hot – a faint wisp of smoke is your cue.

Step 2: Add High-Smoke Oil

Pour 1-2 tablespoons of a high smoke point oil (grapeseed, avocado, or canola) into the hot skillet. It should shimmer immediately.

Step 3: Sear for the Crust

Carefully place the steak in the skillet. Listen for that satisfying sizzle! Don’t move it for 2-3 minutes until a beautiful, deep brown crust forms.

Step 4: Flip, Baste, and Flavor

Flip the steak. Immediately add 2-3 tablespoons of butter, a few smashed garlic cloves, and fresh herbs (rosemary, thyme) to the pan. Tilt the pan and continuously spoon the melted, flavorful butter over the steak for another 2-3 minutes.

Step 5: Check Internal Temperature

An instant-read meat thermometer is your best friend. Insert it into the thickest part of the steak. Remember, the temperature will rise 5-10 degrees while resting, so pull it slightly early:

  • Rare: 125-130°F (52-54°C)
  • Medium-Rare: 130-135°F (54-57°C)
  • Medium: 135-140°F (57-60°C)

Step 6: The Essential Rest

Transfer your steak to a cutting board and let it rest uncovered for 5-10 minutes. This critical step allows the juices to redistribute, ensuring a tender, moist, and flavorful steak. Patience is a virtue here!

Quick Tips for Steakhouse-Quality Results

  • Don’t Overcrowd: Cook steaks in batches if needed to maintain high skillet temperature.
  • Press Gently: Briefly press the steak with tongs for full contact and an even sear.
  • Consider Compound Butter: Prepare butter mixed with herbs and garlic ahead of time for extra flavor.
  • Reverse Sear for Thick Cuts: For steaks over 2 inches, start in a low oven (250°F/120°C) until 10-15°F below target, then finish with a hot cast iron sear.

Perfect Pairings

Complement your Delmonico with simple sides like mashed potatoes, roasted asparagus, or a crisp garden salad. Let the steak be the star!
