Grilled Wahoo with Romesco Sauce

This week the Virtual Potluck team has partnered with Bertolli Olive Oil to promote Where Flavor Comes From which is all about summer grilling and their Let’s Cook Summer Sweepstakes. This is a sponsored post on behalf of Bertolli.

Are you a Top Chef fan? Do you remember Fabio Viviani, Season 5’s fan favorite? The recipe below as well as others featured by the Virtual Potluck bloggers this week were created by Chef Fabio.

Cod vs. Wahoo

I saw this recipe for cod and knew immediately what I was going to do with that piece of wahoo in my freezer. I live in a fishing community, so fresh seafood is abundant. I can even walk to a local harbor in the afternoon and buy fish that was swimming that morning. It doesn’t get much fresher than that.

Cod, a dense white fish, is caught primarily in the North Atlantic and isn’t available here in coastal North Carolina. Wahoo, on the other hand, is found in tropical and subtropical waters so we have it locally. It’s also a white fish and I thought it would be a perfect substitute for the cod. For those who aren’t familiar with wahoo, all you need to know is that the Hawai’ian word for wahoo (“Ono”) is also the word for “tasty.”

How to Make Grilled Wahoo

Here are my notes about Chef Fabio’s Grilled Cod with Romesco Sauce recipe that appears below:

  • I substituted wahoo for the cod.
  • I had a 1-1/2 pound chunk of fish and I grilled it whole instead of cutting it into individual servings first. I thought it would hold up better on the grill this way.
  • The Grillmaster used a rectangular cutting board and formed heavy duty foil around it to make a container for the fish. Then he put the cutting board underneath the foil for support as he carried the fish to the grill. Brilliant!
  • We put the fish (in the foil) on a hot charcoal grill, then immediately covered it and closed the vent to bring the temperature down quickly. We cooked the fish for about 20 minutes and did not turn it. This allowed the bottom to become amazingly crunchy.
  • I sent The Grillmaster to the store for a poblano pepper and I’m not 100% sure that’s what he came home with. Our romesco sauce had quite a kick, but that’s how we like it. Your mileage may vary.
  • This recipe is really, really easy to make and it won’t heat up your kitchen in warmer weather.

  • 1 large firm tomato, seeded and chopped
  • 1 tablespoon Bertolli® Extra Virgin Olive Oil
  • 1 tablespoon Bertolli® Pinot Grigio White Wine Vinegar

  • 2 cloves garlic
  • 4 (6 ounce) cod fillets
  • 1 tablespoon Bertolli® Classico Olive Oil
  • 4 lemon wedges
  • 8 leaves fresh basil
  1. Grill peppers, turning occasionally, 20-25 minutes or until skin is black on all sides.
  2. Place in a large bowl, cover with plastic wrap and let cool, 15 minutes. Peel peppers.
  3. Process tomato, peppers, Bertolli® Extra Virgin Olive Oil, Bertolli® Pinot Grigio White Wine Vinegar, walnuts, brown sugar, chili powder, salt, black pepper and garlic in a food processor until smooth or desired consistency.
  4. Brush fish with Bertolli® Classico Olive Oil. Season fish, if desired, with salt and black pepper. Place piece of aluminum foil on grill grate.

I substituted a 1-1/2 pound piece of wahoo (ono) for the cod and grilled it in one chunk so it would hold up better on the grill.

    Nice dinner, I love flaky and tender fish. With the warm temperatures hitting us now this would be a great dish to make.

  2. says

    Fabio is my favorite and I was really excited to participate in this promotion. I want to try all of the recipes and as soon as I get some fish, I’m trying this one. The crunchy bottom on the fish sounds so good and the sauce….yum!

  3. says

    I love grilled fish. Every time I want fish my man wants it breaded and deep fried. i will have to make this for him. (And ME).

  4. says

    My 10 year old son caught a 70 lb. Wahoo in the Gulf of Mexico. Wow! What a delicious fish that was! Lasted us all winter.
    This recipe looks great, and you just can’t go wrong with wahoo.

  5. moonsword says

    That sauce looks amazing…a little kick is just what I like!
    I’ve never used their Pinot Grigio White Wine Vinegar. I’ll have to look for it next time I shop. Thanks for sharing the recipe!

  6. deb healing says

    Wahoo is one of my favorites and I’m a sucker for poblano peppers…will have to give this a try real soon. Thanks.

  7. says

    These flavors all sound fabulous together! I am a fan of wahoo too, so great choice. Too funny about the grill master and the pepper. My own husband is a very capable man, when it comes to many things, but grocery shopping is not one of them! He his pretty good at the grill though, so I’m pinning your recipe, and letting him cook it :-)
