Grilled Marinated Skirt Steak with Peperonata is a dish you’ll want to put on repeat all summer long!  The skirt steak is marinated in a balsamic vinegar and soy sauce combination, cooks quickly on the grill and pairs perfectly with peperonata, a delicious olive-oil braised bell pepper and onion combination.  Steakhouse Creamed Spinach is perfect on the side!

The inspiration behind this recipe:

The weather this past weekend was perfect for outdoor grilling.  As with everyone these days, we’re trying to not be wasteful and use things that need to get used before buying anything else.

We’ve been working on a bag of Costco sea scallops and some ready-made meals in our freezer.  A skirt steak I dropped into a marinade in a zipper-top bag last summer and then froze because we ended up not getting to it was next on our list.

First of all, I don’t recommend placing the steak in the marinade, putting it in the freezer and forgetting about it for eight months!  Two months in the freezer?  Absolutely!

I was pleasantly surprised even after it had been in the freezer in the marinade for that long.  We had a bunch of bell peppers to use so here is Grilled Marinated Skirt Steak with Peperonata!

What is skirt steak?

Skirt steak is a long, flat piece of meat from below the ribs with plenty of connective tissue.  It can be quite long–up to two feet long!  Skirt steak is one of the most flavorful cuts from the cow however, it’s also one of the toughest.

Because it has a loose structure, skirt steak absorbs the flavor of marinades quite well.  The best way to cook a skirt steak is quickly at high heat so it’s perfect for grilling!

What is peperonata?

Peperonata is a versatile, rustic Italian vegetable dish of stewed bell peppers, onions, tomatoes, garlic, capers and fresh herbs.  It’s served hot, warm or cold as antipasto, a side dish, condiment, tossed with pasta, on pizza or on bread.  It’s perfect with grilled meat, poultry and fish.

How to make Grilled Marinated Skirt Steak with Peperonata:

  • Mix up the marinade.  The marinade is made with simple ingredients you probably already have in your pantry:
    • Soy sauce
    • Balsamic vinegar
    • Olive oil
    • Tomato paste
    • Garlic
  • Place the steak in the marinade using either a large plastic zipper-top bag or a non-reactive bowl.
  • Marinate for 8 hours or overnight.

  • While the skirt steak is marinating or right before grilling, make the peperonata.
  • Typically, only sweet red, yellow and orange peppers are used, but I used what I had which was a combination.  Use red or white onion.

  • Cook the peppers, onions and garlic until they’re nice and soft.
  • Add diced tomato, capers, red wine vinegar and fresh herbs.  Basil is typically used in peperonata however our basil plants just went in and I didn’t want to start plucking leaves from them.  I have an abundance of oregano that’s back from last year so I used that and parsley.  So good!!

  • Then, grill the skirt steak.  Remove from the marinade, pat dry and place on a preheated grill.  Three to five minutes per side is all it needs!

  • Let it rest then thinly slice against the grain.  If your skirt steaks are long, you’ll want to cut them in half widthwise, then slice against the grain.  You’ll be amazed at how tender this tough cut can be!
