Healthy Ratatouille Recipe Variations

Low Carb Ratatouille

All the carbs in this recipe come from veggies, so they are healthy carbs! If you do not eat veggies because you don’t like the carbs, then this is not the recipe for you as it is 100% veggies. You can however boost the protein with collagen powder, or by serving with chicken to balance out the nutrition more.

High Protein Ratatouille

You can add 1-2 scoops unsweetened and unflavored collagen or protein powder to the recipe. Mix it into the tomato sauce just before moving to the casserole dish. You can also serve this with a chicken breast or some baked tofu to boost protein.

Gluten-Free Ratatouille

This Ratatouille is already gluten-free, just be sure to serve it with gluten free sides.

Low Sodium Ratatouille

I was able to keep the sodium very low in this recipe, just be sure not to add any salt and you are good to go.

Low Fat Ratatouille

You can omit the olive oil spray if you like. Just Lowe the heat on the onions and add 1 tablespoon of water. Then cover and sweat them without the oil.

  • Round Baking Dish


  • Olive Oil Spray
  • 1 medium onion chopped
  • 1 red bell pepper
  • 1 medium eggplant
  • 1 zucchini
  • 1 yellow squash
  • 3 plum tomatoes
  • 3 garlic cloves
  • ½ cup chopped fresh basil
  • Leaves from 2 thyme sprigs
  • 1 teaspoon red wine vinegar
  • Freshly ground black pepper



  • Preheat oven to 370 degrees, spray a baking dish with olive oil.
  • Spray a skillet and heat over medium heat. Add the onions and sauté for 10 minutes, until tender.
  • Meanwhile, thin slice the bell pepper, eggplant, zucchini, and yellow squash. You can use a mandoline slicer if you have one.
  • Once the onions are soft, add in the tomatoes, thyme leaves, garlic, basil, and vinegar, and cook for 5 minutes, stirring often to avoid burning.
  • Add the tomato sauce to a baking dish, then layer with sliced vegetables like in the movie. I like to stack the veggie slices in my hand, then add to dish… it makes it much easier.
  • Spray with olive oil, cover with parchment paper, and bake for 60 minutes.
  • Remove the parchment paper and serve hot.
