This zucchini side dish is full of onion, tomato, herbs, and of course zucchini to make a bright and fresh side that tastes out-of-this-world delicious!


  • 3 tablespoons butter or olive oil
  • 1 large onion, diced, about 1 cup
  • 2 cloves garlic, minced
  • 1 medium zucchini (about 2.5 inches in diameter)
  • 2 or 3 fresh tomatoes, diced
  • 1/4 cup your favorite fresh herbs
  • Salt and pepper to taste


  1. In a large skillet, heat the butter over medium to medium-high heat until melted.
  2. Add the onion, and saute until the onion starts to get clear on the edges, about 5 minutes.
  3. While the onion is cooking, cut the ends off of the zucchini, and then cut it in to fourths long-ways. Slice each quarter into 1/4- to 1/2-inch slices.
  4. When the onion is starting to go clear on the edges, add the garlic and chopped zucchini.
  5. While the zucchini is cooking, coarsely dice your fresh tomatoes.
  6. When the zucchini is cooked to your liking (I like it al dente), add the tomatoes. Stir to combine, and heat through without over-cooking the tomatoes.
  7. Remove from the heat, and add your fresh herbs and plenty of salt and pepper to taste.
  8. Serve right away.


  • I love to use cilantro, basil, chives, or parsley for this dish, or a combo of herbs. If using an herb such as rosemary or thyme, only add about a tablespoon because they are a lot stronger than the others listed.
  • Don’t overcook the zucchini unless you truly like it soft. Just a touch of crunch left in it is perfect.
  • If using 1 medium or 2 small zucchinis, then there is no need to peel or remove seeds. If you are trying to use up a large zucchini, I would peel off the outside and remove the big seed after quartering it.
  • Feel free to use a good quality olive oil in place of some or all of the butter.
  • There is a whole lot of onion in this dish. If you aren’t an onion lover, then feel free to reduce the amount. I wouldn’t go less than a 1/3 cup of chopped onion for flavor, though.
