What is gremolata? 

Most of us have probably heard of the name but what is gremolata? Essentially, it’s a green sauce or condiment made from parsley, lemon, and garlic. It’s commonly used to garnish osso buco (braised veal shank) but it can accompany many different dishes! 

It is bright and tangy, and it’s the perfect flavor lift for this grilled tuna steak!

This particular gremolata recipe also includes preserved lemon rind, an ingredient commonly used in Moroccan dishes. This not only adds a layer of complexity in the flavor, but also some visual interest in your gremolata. 

How to make this grilled tuna steak

Like I said above, one of the best things about this recipe is how simple and quick it is to make. Turn your gas grill on high heat and don’t forget to oil it to prevent sticking! 

If you prefer, you can fry the tuna in a pan as well. Simple turn the heat on medium-high and add a tablespoon of your oil of choice.

Try gremolata on different foods

Ever need to freshen up your grilled veggies or add some zest to a soup? Gremolata is a great sauce to have in your back pocket! (Well, not actually in your back pocket, that would be gross…) It both lightens rich, heavy dishes and adds a tang to more simply flavored foods. One of my favorite ways to use it is as a garnish on pork chops!
