How To Know When Steak Is Done: The Importance of a Meat Thermometer

Use A Meat Thermometer!

For optimal tenderness and flavor, aim for 130–135°F for medium-rare or 145°F for medium. Flat iron and flank steak are best enjoyed at medium-rare, making this steak sandwich recipe the most tender and enjoyable.

Don’t have a thermometer? Gently press the center of the steak. If it feels soft and springy, it’s likely medium-rare; slightly firm indicates medium.

Top Steak Cooking Tips:

  • Start hot: Ensure your grill or pan is fully preheated to achieve a beautiful sear and prevent sticking.
  • Pat dry: A dry surface promotes better browning.
  • Don’t move it: Allow the steak to cook undisturbed for a crispy crust.
  • Rest before slicing: Let the steak rest for approximately 10 minutes to retain its juices.
  • Slice against the grain: Thin slices ensure tenderness and make the steak sandwich easier to eat. A sharp knife is essential!

Storage Instructions

This steak sandwich is best enjoyed immediately after assembly. While steak doesn’t store particularly well, the lemon aioli can be stored in an airtight container in the refrigerator for up to 3 days.

Ingredients

Steak
  • 12 ounces flat iron steak or sous vide steak, see note 1
  • Olive oil
  • Salt and pepper
Quick Lemon Aioli
  • 1/2 cup mayo (Best Foods/Hellmans)
  • 1 teaspoon minced garlic (very finely minced)
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon lemon zest
Sandwiches
  • 2 Ciabatta rolls
  • Fresh arugula
  • 1 large avocado ripe, thinly sliced
  • 1 batch pickled onions (click link)

Instructions

Steak

  • Pat the steak dry with paper towels. Preheat the grill to 450°F. Clean and oil the grates to prevent sticking. Drizzle the steak with olive oil and season generously with salt and pepper.
  • Place the steak on the hot grill, close the lid, and cook 4 to 5 minutes per side, or until it reaches 130–135°F for medium-rare or 145°F for medium. Transfer to a cutting board, tent loosely with foil, and rest for 10 minutes. Slice very thinly against the grain.

Sandwiches

  • Make the aioli: Stir together the mayo, garlic, lemon juice, and lemon zest in a small bowl until smooth. Refrigerate until ready to use (flavor gets better as it sits!)
  • Assemble: Toast the ciabatta rolls. Spread aioli generously on the inside of both halves. Layer the bottom with arugula, avocado, sliced steak, and pickled onions. Close the sandwich and serve right away.

Recipe Notes

Note 1: Find the fibers on the steak and determine how they are running along the steak. Once you find that grain, slice perpendicular (here’s a visual). This will keep the meat juicier and much more tender. It’s easier to chew when cut against the grain. If you’re near Costco, their sous vide steak is my favorite shortcut here!
Storage: Best eaten right after assembling. The lemon aioli keeps up to 3 days in an airtight container in the fridge.
