Ingredients

For the Roasted Grapes & Shallots

1 cup seedless red grapes (Note 4)
1 medium shallot thinly sliced
1 tablespoon olive oil
1 teaspoon balsamic vinegar (Note 5)
1 teaspoon fresh thyme leaves or ½ teaspoon dried
pinch of kosher salt

For the Steak

¾ to 1 lb NY strip steak (Note 3)
1 teaspoon kosher salt
½ teaspoon freshly ground black pepper
1 tablespoon olive oil for searing

For Finishing

⅓ cup crumbled blue cheese Gorgonzola, Roquefort, or Maytag (Note 6)
Optional: balsamic glaze or quick pan reduction
Optional: arugula or baby greens for serving

Instructions

Preheat oven to 425 F (220 C).
In a bowl, toss 1 cup seedless red grapes and 1 medium shallot (thinly sliced) with 1 tablespoon olive oil, 1 teaspoon balsamic vinegar, 1 teaspoon fresh thyme leaves, and a pinch of kosher salt. Set aside.
Pat ¾ to 1 lb NY strip steak dry and season on both sides with 1 teaspoon kosher salt and ½ teaspoon freshly ground black pepper.
Heat 1 tablespoon olive oil in the cast iron skillet over medium-high heat. Once hot, add the steak and sear for 2–3 minutes per side, until browned and crusted but not cooked through (Note 7).
Remove skillet from heat. Nestle the grape and shallot mixture around the steak in the pan.
Transfer skillet to the oven and roast for 6–10 minutes, depending on thickness and preferred doneness (Note 8):
125–130 F = rare to medium-rare
135 F = medium
Transfer steak to a cutting board and tent loosely with foil. Rest 5–10 minutes. Meanwhile, stir grapes and shallots gently in the skillet.
Optional: for extra flavor, place skillet over low heat, deglaze with a splash of red wine, broth, or water, and scrape up browned bits for a quick reduction sauce (Note 9).
Slice steak thinly against the grain. Arrange over the roasted grapes and shallots. Sprinkle with ⅓ cup crumbled blue cheese and drizzle with pan juices or balsamic glaze. Serve immediately.

Notes

Cast iron retains heat exceptionally well, ensuring a golden sear. A 12-inch size gives space for both steak and grapes.
The best way to guarantee foolproof results. Insert into the thickest part of the steak.
Ribeye is marbled and juicy, while NY strip is leaner but still flavorful. Both are great here.
Red seedless grapes roast into sweet, caramelized bites. Green grapes are more tart if substituted.
Aged balsamic adds sweetness and depth. Standard balsamic works fine too.
Add right before serving so it softens without fully melting. Choose one to match your taste preference: mild (Gorgonzola Dolce), medium (Maytag), or bold (Roquefort).
The steak should release easily from the skillet when it’s ready to flip. If it sticks, give it another 30–60 seconds.
Times vary based on thickness. Always check with a thermometer instead of guessing.
Deglazing lifts flavorful browned bits from the pan, creating a quick sauce to spoon over the steak.

Make Ahead Tips

Shallots & grapes. Toss them up to 1 day ahead and store covered in the fridge. This shaves 5 minutes off prep.
Steak seasoning. Pat dry and season with salt up to 24 hours in advance (refrigerated, uncovered). This dry brine helps draw in flavor and ensures a better crust.
Sauce shortcut. If making the pan reduction, you can prepare it while the steak rests so everything finishes together smoothly.

Storage

Store leftovers in an airtight container for up to 2 days. Reheat gently (covered, low oven or skillet on low heat) to avoid overcooking the steak.
