Zucchini and tomatoes cook together with garlic, onion, and spices for a healthy and delicious side dish.

Budget-friendly, versatile, and slightly sweet zucchini pairs well with almost any other vegetable, but goes especially well with tomatoes. If you’re looking to use up all your fresh zucchini this summer or just love it, then this recipe is for you!

I was inspired to make this recipe after seeing a similar version on the Instant Loss site.

Key Ingredients

Zucchini has a mild, sweet flavor that plays well with other vegetables. Zucchini can be found year round but is in season during the summer months.

Diced tomatoes add sweetness and acidity to the dish.

Onion soaks up the juices of the tomatoes and pair perfectly with the zucchini.

Garlic has a nutty, sweet, and mild flavor once cooked that goes exceptionally well with vegetables.

Spices like sea salt are essential to bring out the flavors in the dish but red pepper flakes, dried basil, and black pepper give it something extra special.
