Zucchini & Tomatoes (Bone Fish Grill Copy Cat Recipe)

As an Amazon Associate and member of other affiliate programs, I earn from qualifying purchases.

There used to be a “seasonal side” of Zucchini & Tomatoes at the Bone Fish Grill. It was always one of my favorites! The combination of fresh summer vegetables; Roma tomatoes, zucchini, and onions, all sauteed with butter and olive oil, and served with fresh basil leaves and shredded parmesan cheese for the perfect amount of Italian seasoning. This is one delicious side dish, my friends!

I loved them so much, that I decided I needed to learn to make this zucchini side dish at home. This zucchini and tomatoes recipe has been on my website since 2014. When the end of the summer months roll around, I can always count on getting asked that age-old question “do you want any zucchini?”

August 8th is actually deemed “Sneak a Zucchini on your neighbor’s Porch Day.” Did you know that? Makes sense, because this time of the year our own gardens and our farmer’s markets are bursting with fresh zucchini!

I love to find new ways to use these healthy squash. In fact, I have a whole recipe post dedicated to lots of sweet and savory recipes that use zucchini!

This particular recipe is not only Keto friendly, it is low carb, low in calories and packs 2 grams of fiber per serving. You can see the rest of the nutritional information in the recipe card below.


This easy recipe contains only a handful of ingredients and simple seasonings. For exact measurements and cooking times, scroll to the printable recipe card at the bottom of this post.

  • green zucchini – I typically grab the small zucchini for this recipe. Save the big ones for grating into zucchini bread.
  • tomatoes – any kind of tomatoes will work. Just make sure they are nice and ripe. Roma, vine tomatoes, and even cherry tomatoes are perfect.
  • sweet onion – I prefer the mellow taste of the sweet onion for this recipe.
  • olive oil and butter – for sauteeing
  • Parmesan cheese – you can buy the pre-shredded but I prefer to shred my own.
  • fresh basil – you could substitute dried basil, but nothing beats fresh herbs!
  • salt and black pepper – to taste.


This great side dish is all made right in one skillet! Fewer dishes? Count me in!


In a large skillet over medium-high heat, add butter and oil.


Add zucchini slices, onion, and tomatoes, and sautè for about 5-8 minutes.

Until the zucchini is your desired tenderness.


Remove from heat. Add in basil, salt, and fresh ground pepper. Stir to combine.


Pour into a serving dish, and top with Parmesan cheese.


Serve hot, with more cheese if desired.

tip: Or skip the casserole dish and serve it right out of the hot skillet.

    It was a tasty side dish and I will cook it again

  6. My mom used to make this a lot in summer. She also served it as a side dish, but I sometimes ate a big bowl with a thick slice of bakery bread for lunch. I’ve been craving it and wanted some idea of proportions. Thank you! As I remember, it re-heats well, and even freezes ok. I’m going to make a batch this afternoon.
