Low-Carb Roasted Zucchini Recipe

I’ve been seeing these viral Thomas Keller zucchini videos everywhere lately, and I just had to put my own Mediterranean spin on them. This cooking method creates the most flavorful, crispy, and pillowy zucchini. It’s so good, you won’t want to cook zucchini any other way! 

This method of preparing zucchini, made viral by renowned chef Thomas Keller, comes out truly delicious without the topping, but the flavor and texture are so much better when you add the feta, crushed pistachios, fresh mint, lemon zest, and sumac. 

And to make things even better, it’s just as easy to make as it is delicious. With just a five-minute pan-fry and a 10-minute roast, you’ll have this delicious dish on your serving platter in no time!

Made with 3 Simple Ingredients

Zucchini: I recommend using a medium zucchini for even cooking.

Salt: Salt is used to season and drain out excess moisture from the zucchini.

Avocado Oil: Avocado oil has a higher smoke point and is a heart-healthy alternative to olive oil.

Level Up With This Easy Garlic, Feta, & Mint Sauce! 

  • Greek Yogurt: As the base for the sauce, it adds a tanginess and makes everything nice and creamy. 
  • Feta: The perfect salty cheese to add some extra flavor to your zucchini.
  • Garlic: Everything tastes better with garlic! 
  • Fresh Mint: Mint is a classic Mediterranean herb that pairs wonderfully with zucchini.
  • Lemon: Lemon adds a touch of acidity to take the flavor profile up a notch. 
  • Salt & Pepper: A little salt and pepper bring all the other flavors to life.

Finish It Off with Toppings

  • Crumbled feta– for that creamy, salty extra.
  • Fresh mint– the fresh, floral flavor adds something special.
  • Crushed pistachios — adds a nice crunch!
  • Sumac — a Middle Eastern spice that is sharp and tart with a sprinkle of floral sweetness.

Substitutions

Zucchini is a versatile vegetable that tastes excellent with a variety of different flavors. If you’d like to put your own spin on this Thomas Keller zucchini recipe, here are some ideas for inspiration:

Sauce: Go for the original Thomas Keller sauce vierge, made of tomato concasse, champagne vinegar, shallots, olive oil, salt, and parsley. Or make an Italian gremolata sauce!

Cheese: Instead of crumbled feta, sprinkle the top of your roasted zucchini with some goat cheese.

Herbs: Not a fan of mint? Try using other fresh herbs like thyme, oregano, or rosemary.

Toppings: Some homemade breadcrumbs would taste amazing with this zucchini. It’ll add buttery flavor and a nice crunchy texture. 

Oil: I used avocado oil, but you can also use extra virgin olive oil if that’s what you have.
