We only have a couple more days before it’s officially Autumn, but over the weekend my sister Val came for a wedding shower for my beautiful niece Emma, and when she was here Val gave me a big bag of zucchini, yellow squash, and cucumbers from her garden. Val had given me this recipe for Val’s Easy Yellow Squash with Tomatoes and Parmesan a few years ago at this same time of year, so it seemed like the perfect time to make this again and get better photos.

This combination of yellow squash stir-fried with onion and garlic, barely warmed tomatoes, and Parmesan is delicious for a low-carb and gluten-free way to use summer squash, and this literally takes minutes to make. (My sister Val is a genius at these easy recipes using garden produce and Broiled Zucchini with Mozzarella and Pepperoni is another easy recipe she makes with her garden squash.)

If you still have yellow squash in the garden or you’re getting it at the Farmers Market, I hope you’ll put this recipe on your *Must Try* list! You’ll make it over and over once you try it.

What ingredients do you need for this recipe?

  • olive oil, divided
  • yellow onion
  • garlic cloves, finely minced or Minced Garlic (affiliate link) from a jar
  • yellow summer squash
  • cherry tomato halves
  • salt and fresh ground black pepper to taste
  • finely grated Parmesan cheese

What is Yellow Squash?

Yellow squash refers to yellow summer squash, which is a vegetable that’s in the same family as zucchini. There are quite a few varieties of yellow squash, and some are curved and some are straight, but all have the pleasant mild flavor that’s good in so many dishes.

This would be delicious with Grilled Chicken with Lemon, Capers, and Oregano or Grilled Lamb Chops with Garlic, Rosemary, and Thyme for a low-carb meal. If you’re not up for grilling I’d love it with Artichoke Chicken Bake.

  10. Barbara, mine has really slowed down this last week too.

  11. I love everything about this dish. Unfortunately, my squash is done for the year.

  12. TW, you could definitely make it with zucchini as well, or even all zucchini if that's what you have!

  13. I love this – it's my kind of weeknight vegetarian dish – very flexible, too. I'm sure I could throw in a little green zucchini lurking in the fridge for even more color.

  14. Dara, Jake and I inhaled this! Which was ok, because it's pretty healthy.

  15. What a great way to prepare yellow squash! A little tartness with tomatoes and saltiness with the Parmesan.

  16. Lydia, my stepmother used to be so proud of her dark gold squash, even though I tried hard to convince her that they were better when they were smaller and a more pale yellow!

    Becky, glad to hear I'm not the only one with a big surplus of squash! Hope you enjoy.

  17. Can't wait to try this. I just need to wait to get tomatoes from my CSA tomorrow and I can make it!

    I'm with you on the crops not knowing it's fall. I have so much squash on my hands right now.

  18. What a great recipe, one that doesn't drown out the delicate flavor of the squash. Thanks for the tip about looking for the ones that are more pale in color.
