Why Use a Flank Steak for this recipe?

The flank is a single, boneless, thin piece of muscle located behind the rib cage, beneath the loin, and in front of the rear legs.  It usually weighs between one/two pounds.

Because this cut of meat is thin, it takes very well to marinades, making it tender and flavorful and it’s also very easy to roll.

How to make Spinach Stuffed Flank Steak?

  1. Saute the spinach: In a nonstick skillet, saute onion and garlic. Then, add the spinach. Once done, transfer the mixture to a bowl, and add crushed walnuts, blue cheese, and mix to combine. 
  2. Butterfly and stuff the steak: Flatten the steak to about 1/2-inch the thickness and then, spread evenly the stuffing over it.
  3. Roll it: Carefully roll it, and tie with kitchen string, and brush with olive oil. 
  4. Bake: Lastly bake and let it rest for a few minutes prior to serving. 
  5. Serve it: This is a delicious and flavorful meal on its own. We love topping it with our homemade chimichurri sauce

Can I stuff the steak with other cheeses?

Blue Cheese is amazing in this recipe, BUT if you are not a fan, you can replace it with Feta Cheese or Goat Cheese. Also, you can use mozzarella cheese for this Stuffed Flank Steak recipe.


We like cooking it at a higher temperature to lock in the juices and make it extra crispy on the outside. Our cooking time is at 425 degrees F for about 35 minutes, followed by an additional 5-10 minutes of broiling. 

Also, once cooked, it is important to let the steak rest for at least 5 to minutes prior to serving. 


Everyone loves their meat cooked differently. Below you can find the internal temperature of the steak for each desired doneness. Please remember that the meat will continue to cook while it rests, and it will increase its temperature by about 5 more degrees. To check the internal meat temperature, it is best to use a meat thermometer.

  • Rare: 120 F degrees (with rest time it will increase to 125 F degrees)
  • Medium Rare: 130 F degrees (with rest time it will increase to 135 F degrees)
  • For Medium: 140 F degrees (with rest time it will increase to 145 F degrees)
  • Medium Well: 145 F degrees (with rest time it will increase to 150 F degrees)
  • Well Done: 155 F degrees (with rest time it will increase to 160 F degrees)

Recipe Tips:

  • Use quality meat, preferably organic beef because the meat will be tastier and juicier.
  • When buying a flank steak, choose one that is as uniform in thickness as possible. Also, it is OK for it to be thicker in the center than at the ends.
  • This recipe works best with 2-pound steak as you need to butterfly it in half. Hence, the thickness of the steak is important. You can also ask your butcher to butterfly it for you.
  • This recipe tastes best when cooked to medium-rare or medium. I have family members that don’t like medium-rare meat, so I tend to cook it medium, with a light pink center.
  • If you overcook it, the meat will become tough and tasteless.
  • Also, the recipe asks for a lot of garlic, what can I do, we love garlic in my family! However, you can use less or more, based on your own preference.
  • The ground walnuts are a very nice addition, their nutty flavor complements well the blue cheese, if you don’t have any on hand, you can skip them.

Stuffed Flank Steak with Spinach and Blue Cheese

Stuffed Flank Steak with Spinach and Blue Cheese is packed with garlic, caramelized onions and walnuts. A very easy dish that is packed with flavor!

Stuffed Flank Steak with Spinach and Blue Cheese is packed with garlic, caramelized onions and walnuts.
  • Prep Time15 MIN
  • Cook Time45 MIN
  • Servings 6


  • 1 (2 lb) flank steak butterflied
  • 1 medium onion chopped
  • 10 cloves garlic minced
  • 3 cups fresh spinach chopped
  • 6 oz crumbled blue cheese
  • 1/2 cup ground walnuts
  • 1/2 teaspoon salt divided
  • 1/2 teaspoon black pepper divided
  • 3 tablespoons olive oil

Top of the steak:

  • 1 tablespoon black pepper
  • Twine to tie the meat

Chimichurri Sauce:

  • 1/4 cup parsley chopped
  • 1/4 cup cilantro chopped
  • 6 cloves garlic
  • 3 tablespoons red wine vinegar
  • 1 teaspoon crushed red pepper
  • 1 tablespoon oregano leaves
  • 1/2 cup extra virgin olive oil
  • salt and pepper to taste


  • Pre-heat the oven to 425. Butterfly the steak, look for it to be between ¼”-1/2” thick. Place it on a cutting board.
  • If you spot parts that are unevenly thick, flatten them out with a meat mallet. Season the steak with salt and pepper and set aside.
  • Place a medium-large skillet over medium heat. Add 1 tablespoon of olive oil, once the oil is hot add the chopped onion and minced garlic. Cook for 3-4 minutes, stirring occasionally, until the onion is soft and starts to turn golden brown at the edges.
  • Add chopped spinach to the skillet and cook for 3-4 minutes, stirring occasionally, until the spinach is soft. Set aside to cool off.
  • In a large mixing bowl, combine ground walnuts, crumbled blue cheese and the spinach mixture. Stir well to combine. Season with salt and pepper to taste.
  • Turn the steak so the “grain” of the steak is running left to right in front of you. Spread the spinach mixture evenly across the surface of the butterflied steak, one inch away from the sides of the steak.
  • Starting with the side closest to you, roll the steak tightly forward, around the filling, until the roll is complete. Use twine to tie up the rolled steak about every 2 inches. If you see any filling escaping out the sides, tuck it back in.
  • Add 1 tablespoon of olive oil to a 9×13 baking dish, brush the sides and bottom of the dish with the oil.
  • Transfer the stuffed steak roll to the baking dish and using a pastry brush, brush the remaining 1 tablespoon of olive oil all over the surface of the steak.
  • Sprinkle with the remaining 1 tablespoon of black pepper. Place in the pre-heated oven and bake for 35 minutes. Turn the oven to broil and broil for 5-10 minutes. Watch it closely not to burn it.
  • Remove from the oven, cover the steak with aluminum foil and allow the steak to rest for 15 minutes before removing the twine and slicing.
  • Cut into slices with a serrated knife and serve.

Chimichurri Sauce:

  • In a food processor, combine the parsley, cilantro, red wine vinegar, garlic, oregano and crushed red pepper. Process until smooth.
  • Season with salt and pepper. Transfer the sauce to a bowl and pour the olive oil over the mixture. Let stand for at least 20 minutes.
  • Stir and drizzle over meat.
