Summery Sautéed Zucchini and Tomatoes Recipe

This is one side dish that looks as good on the plate as it tastes. The bright red fresh summer tomatoes and gorgeous green zucchini definitely make you want to take a picture of this incredible summer dish. I would say, without a doubt, that sautéed zucchini and tomatoes are Instagram-worthy. 

Of course, food should also taste great, not just look picture-perfect. You don’t have to worry about that! I have made this recipe countless times and tweaked the ingredients to give you the most flavor in every bite. The fresh zucchini, sweet cherry tomatoes, and blend of garlic, onions, and seasonings are truly delicious. 

The whole recipe takes about 20 minutes from start to finish, but the best part is that you can make it in just one large skillet. That means fewer dishes, less mess, and more time outside enjoying the summer sun! So fire up your grill to make some BBQ chicken, and toss your zucchini and tomatoes into the pan to cook. You will have a show-stopping summer meal in no time!

Recipe Ingredients

To print: see recipe card below

  • 3 tablespoons extra virgin olive oil
  • 3 cloves garlic – I like to use fresh chopped garlic, but you can also use 1 teaspoon of garlic powder instead.
  • 1 red onion 
  • 4 medium zucchini – Make sure your zucchini has a nice, dark green color. 
  • 2 teaspoons Italian seasoning – Italian seasoning is a blend of dried basil, oregano, and parsley. Be sure to grab a seasoning that is unsalted. 
  • 1/2 teaspoon red pepper flakes – Skip the red pepper flakes if you’re not a fan of heat. 
  • 2 teaspoons kosher salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons tomato paste – If you have extra tomato paste, freeze it! You only need a little for this recipe, so save the rest of the can for later.
  • 1 pint cherry tomatoes 
  • 1 tablespoon lemon juice
  • 1/4 cup parmesan cheese

Variations

  • Use two green zucchini and two yellow squash. Yellow squash has a mild flavor that goes well with the zucchini and tomatoes. It also adds a nice pop of color to the summer side dish. 
  • Replace the cherry tomatoes with one large, chopped tomato. Cut your large tomato into pieces that are about one inch in size. You don’t want to dice the tomato too small, or it will turn to mush as it cooks. 
  • Skip the parmesan cheese to make this recipe for sautéed zucchini and tomatoes vegan.
  • Add a sprinkle of fresh basil for a bright, herbaceous taste.

Directions for How to Make Sautéed Zucchini and Tomatoes

  1. Sauté the aromatics: Heat the olive oil in a large skillet over medium-high heat. Add the garlic and onion, and sauté for 6 to 7 minutes or until the onions start to brown.
  2. Cook: Add the zucchini slices, Italian seasoning, red pepper flakes, salt, and freshly ground black pepper. Continue to cook for 6 to 7 minutes, softening the zucchini.
  3. Add the tomatoes: Once you can easily pierce the veggies with a fork, add the tomato paste and tomatoes. Stir to combine, and heat for 4 to 5 minutes or until the tomatoes begin to break down.
  4. Top: Remove the sauteed zucchini skillet from the heat, and mix in the lemon juice and cheese. Serve right away!

Quick Tip

Try making this zucchini and tomatoes recipe on the grill. To do so, toss all the ingredients except the cheese in a large bowl.

Then, add the seasoned veggies to a grill basket. Cook over high heat for about 10 minutes, stirring occasionally to grill the veggies evenly. Divided the vegetables onto plates, and sprinkle them with the Parmesan cheese.

FAQs

How do you keep zucchini from getting soggy when sautéed?

If you are worried about your zucchini being soggy, you can remove the seeds. The seeds are edible, but they contain a lot of water. The water from the seeds will come out as the zucchini cooks, which can cause it to be soggy. Scoop the seeds out for a crisper zucchini side dish.

Do you need to peel zucchini before cooking?

No! You do not need to peel zucchini before cooking. In fact, the skin has lots of nutrients and it adds a pretty green color to the dish.

How do you know when zucchini is cooked?

Zucchini will be tender when it is cooked. You will be able to easily pierce it with a fork when it is ready.
