About Baked Stuffed Flank Steak

Since I’ve started this blog, our conversations about dinner typically go something like this:

Me: “I need to make a recipe for the blog. What do you want me to cook for dinner?”

Him: “Steak.”

Me: “How do you want it prepared?”

Him: “Just steak, nothing else.”

Me: “But I have to make an actual recipe for this to work.”

Him: “Okay. But I just want steak.”

This is usually the part where I throw my hands up in the air and make a dessert instead.

But not today!

Today I found a happy medium between my steak-loving boyfriend and my desire to try out new and interesting recipes to share with you.

Now, don’t get me wrong: I love a good steak just as much as the next red blooded American (‘Merica!) But I’m also a fan of all things cheesy and flavorful. Easy is a big draw for me, too, and I’ll tell you right now I was really surprised how easy this recipe was to make.

It looks far more complicated than it actually is.

Just mix the ingredients, slather on a steak, wrap it up, bake it, and you’re done – time enjoy your super flavorful dinner!

The hardest part to this whole recipe is probably butterflying the flank steak, but if you’re lucky, you just might be able to find a steak that’s already been butterflied (or have the butcher at the deli do it for you).

Too easy, right?

The funny thing is that I had injured my knee the night before I planned to make this dish, so I sent an old friend of mine to the grocery store with a very specific list of instructions so he could track down everything I needed to make his not-just-plain-steak steak dinner.

And being the crafty guy that he is, he managed to not only find the already butterflied flank steak (prepackaged and already rolled in the “ready to cook” section) but also scored some free cooking twine from the deli to wrap the steaks with.

I should send him to do my busy work more often.

I was worried how the steak would cook through, but it was a perfect medium rare in the middle and a solid medium along the edges.

However, I only broiled ours for about 5 minutes – broiling for 10 minutes would result in a more cooked steak.

And don’t even get me started on the mozzarella, spinach, and sun-dried tomato stuffing – it was simply delicious. I think I could have made a big helping of it and eaten it just on its own.

And I may have stolen some of the overflowing cheese stuffing, straight out of the baking dish, while I waited for the steak to “rest.”

Maybe.

Okay fine, you know me too well; I did exactly that, but at least I had the decency to use a fork this time.

Overall I was extremely happy with this dish, especially since I think it will likely become my go-to dinner for whenever we have company.

It’s easy to assemble and cooks fast – how does that not please a crowd?

Baked Stuffed Flank Steak

10 mins prep + 40 mins cook + 15 mins Resting Time

Yields: 4 servings
Spice up your boring steak dinner by filling a fine cut of meat with spinach, mozzarella, and sun-dried tomatoes. It's easy to tailor to your tastes, too!

Ingredients 

  • 1-2 lb flank steak, butterflied
  • 1 egg yolk
  • 1 and 1/2 cup mozzarella cheese, grated or shredded
  • 1 cup spinach, frozen pkg - thawed, rinsed, and well drained
  • 1/2 cup sun-dried tomatoes, roughly chopped
  • 1/2 tsp garlic salt, divided
  • 1 pinch black pepper, to taste
  • 2 tbsp olive oil

Instructions

  • Preheat oven to 425 degrees F.
  • If you have not already done so, butterfly your steak by lining your knife up parallel with a cutting board and slicing through the center of the steak, stopping just short of cutting all the way through. This will make it so that you can open up the steak like sandwich bread, doubling the original length of the steak. Need a visual guide? Check out this video.
  • Using a meat tenderizer, even out the thickness of the steak, aiming for 1/4 to 1/2 inch thick.
  • In a large bowl, add egg yolk and lightly whisk with a fork. Add spinach and panko bread crumbs, mixing with the egg. Finish off by tossing in the mozzarella and sun-dried tomatoes until all ingredients are thoroughly mixed.
  • Top butterflied steak with cheese stuffing, spreading it out evenly. Leave a 1 inch border along the edges of the steak clear of stuffing. Sprinkle top of stuffing with 1/4 teaspoon garlic salt and pepper to taste.
  • Roll the steak along the "grain" (the ripples in the meat), starting with the smallest end first. Roll the steak tightly and tuck in any stray pieces.
  • Using cooking twine (100% cotton string), snugly loop & tie the twine along the steak in 2 inch intervals. String should be snug enough to slightly compress meat but not so tight it begins to cut into the steak.
  • Place stuffed & tied flank steak on a baking sheet of your choice (I used a 9x13 baking dish). Drizzle the steak with olive oil and use your fingers to thoroughly rub it into the meat. Sprinkle remaining 1/4 teaspoon garlic on top of the steak.
  • Bake in the oven for 35 minutes, then set oven to broil and cook for another 5-10 minutes, to taste. Caution: Depending on how much juice the steak released while cooking, there may be a little smoke while broiling.
  • Remove stuffed flank from oven and let rest for 15 minutes, exposed to air and undisturbed, before serving.

    Super easy dish to make! Had the butcher do the tough part! Delish as is, but think you could get creative with additions to stuffing. Thanks for sharing!

    I made this exactly per the recipe and that was hard because I always adjust recipes, it was exceptional! So much so that I am making it again this weekend dinner party for 12. We like medium rare so watch your oven. Also, Publix and Piggly Wiggly will butterfly your flank steak, the rest is easy.
    Thanks Chrisy!!!

    Wow!! As I was stuffing the steak, I’ll admit I had my doubts. No idea why, but I had a hard time wrapping my head around steak stuffed with cheese. And it came out amazingly delicious! I’m so happy! I used sundried tomato-garlic paste, 4 cheese Italian mix, added chopped mushrooms and shallots to the mix, and didn’t broil. Thank you! I’m blown away!

    • Gina

    What was the purpose of the breadcrumbs and egg yolk because it was just clumpy 😥😔

    Made this tonight and it was delicious! For the stuffing, I chose to do spinach, onions, cheese, bread crumbs and bacon. The only thing I will do differently next time is adjust the cooking time. For 35 minutes at 425, the meat was solidly well done, even to the inside of the roll. I did not need to broil it. Excellent advice to let it sit for about 15 minutes. Helped with slicing for sure.
    Thank you for the recipe 🙂

    How many lbs for a dinner party of 8

      • Gina

      Depends on how big the eaters are; flank steak shrinks, so maybe 6-8pds.

    I really love trying new recipes. Easy to prepare and very versatile. I added precooked bacon pieces and onion. I did not put in the breadcrumbs. My an old friend of mine likes his meat temperature to be medium and I like it more medium well. I left it on broiler for 10 minutes which was way too long. This was my fault so be sure to take it out at 5. Next time I try this I think I’ll put on the grill for the last 5 minutes. The meat was a little tough so I’m wondering if you should marinate the flank steak before you start.

    This was Amazing!! I did a few tweaks to accommodate my family’s taste.

    No Panko or egg. I finely diced fresh garlic, added fresh spinach and fresh basil and used Gorgonzola cheese vs mozzarella. For the sundried tomatoes, I used the ones in the jar that is stored in olive oil. It gave the inside of the mixture just enough moisture!

    • Sue

    This looks like a perfect date night meal – what else would you suggest serving alongside?

    This is another genius recipe! The flavors, the aroma, the colors, well just everything about this dish is perfection.

    This was so good. The stuffing needs some salt and pepper. I would also put pepper in the outside but I like pepper. Thanks for the advice to ask the butcher to butterfly the meat. I think that is the hardest part of this dish.

    • Bonnietunes

    Looks delish! Do you think you can finish the steak on the grill instead of broiling to avoid the smoke?

    • Heather

    Yummy!!!! So
    If I’m cooking for 6 people, how many steaks would you recommend I get? Im horrible at figuring out portions! How do you think this would
    Be with stuffing inside the steak? I have picky eaters🙄

      • Tess

      I make this exact thing with stuffing and mozzarella. It’s awesome

    • Holly

    Can I use cream cheese instead?

    • Kris LaMar

    I didn’t find anything in the recipe about the marinade.

      • Chrisy

      Hey Kris! This recipe actually doesn’t include a marinade.

    • Sonya

    Hi, do you cover the dish with foil when cooking in the oven the first 35 minutes?
