Are Roasted Olives Healthy? 

Yes! Olives are incredibly healthy on their own and provide a great source of vitamin E, iron, calcium, and healthy fats. So, by combining them with warm spices that pack in plenty of antioxidants and heart-healthy olive oil, we made them even healthier!

Ingredients You’ll Need

This roasted olive recipe is so simple, that you probably already have everything you need! 

  • Olives – We used a combination of Kalamata and green olives, but feel free to mix and match whatever you like best.
  • Lemon – A bit of lemon helps cut through the heavy oils, adding a light, refreshing taste to this dish. 
  • Seasonings – For a savory, warm, and slightly spicy taste we included crushed red pepper, thyme, oregano, rosemary, and za’atar
  • Olive Oil – The finishing touch, olive oil enhances the natural flavor of the olives while helping the seasonings to stick.
