Summer Squash Gratin – Healthy Version

I simply love the look of summer squash gratin! Not just the completed dish, but the whole process of making/decorating turns me into an excited little kid. The French were no doubt pretty awesome cooks. The inventors of Baguette, macaroons, Mille-feuille and crepes (my favorite french cuisines :D) have one quality greatest of them all, they eat that crazy amount of cheese and never gains weight! I couldn’t envy anyone more.

The Indian inside me keeps on craving for yum food but the beach lover me is always keeping a close eye on those fatty ingredients. This time I have struck the perfect balance! This colorful and mouth-watering dish which is usually loaded with cheese is now my go to recipe with amazing flavor, loads of fiber, vegetable juice and hardly any cheese. Want to see how? Let’s toss off the cheese (or at least reduce the quantity to bare minimum) and relish the taste of veggies cooked with aromatic spices.

  • sprinkle 1/2 tbsp Parmesan cheese
  • Slide your gratin pan into pre-heated oven

Tada!!!! your gratin is ready to serve! 🙂Summer Squash Gratin


  • Cooking time can be reduced to 45-50 mins by simmering and concentrating vegetable juice before adding to gratin.
  • As you are not peeling squash, Clean veggies thoroughly with produce wash before use
  • It can be a perfect dish for pot luck in this summer season
  • If you do not have Zatar or Thyme, don’t sweat about it. Oregano alone can work too. Just increase the quantity a little and add while tossing your squash pieces.
