Ingredients You’ll Need

The base of this dish is the three stars of ratatouille: fresh tomatoes, sliced eggplant, and zucchini! I slice all 3 of them thinly so I can build many layers of flavor in the dish.
The sauce is made with no-salt diced tomatoes, basil, parsley, Italian seasoning, and olive oil. This goes at the bottom of the baking dish, and catches all the wonderful flavors from the roasting vegetables on top.
I also like to finish this dish off with fresh lemon juice. It adds a light and summery kick, and I find that the acidity works nicely with the flavors of the veggies.
Additions and Substitutions
You can use yellow squash or a different variety of squash if you prefer in place of (or in addition to!) the zucchini.
I used Italian seasonings, but I also like adding Herbs de Provence, a tasty French blend of spices. If you have some on hand, definitely add it in!
Serve up with your favorite protein to make it a meal! You can serve it with sliced low sodium steak or low sodium grilled chicken breasts for a complete meal.
How To Make Ratatouille Without Salt

Step 1: In a large pot, add half of the olive oil (1/4 cup) and saute the grlic, onions, and carrots for 5 to 6 minutes over medium heat until the vegetables have begun to soften.

Step 2: Add in the diced tomatoes with the juices, basil, parsley, garlic powder, and the dried Italian Seasoning. Stir well to combine, and cook for 4-5 more minutes.

Step 3: Once the pot of vegetables have finished cooking, pour them into the bottom of a 13 x 9 inch baking dish and set aside.

Step 4: Thinly slice the zucchini, eggplant, and tomatoes so they are roughly the same size.

Step 5: Preheat the oven to 425 degrees Fahrenheit. Layer the sliced zucchini, eggplant, and tomatoes in the baking dish on top of the cooked vegetables, alternating the vegetables throughout the dish.

Step 6: Brush the vegetables with the remaining 1/4 cup olive oil. Cover with foil, and bake for 30 minutes. Remove the foil, and bake for an additional 20 minutes, or until the vegetables are tender.

Step 7: Carefully remove the baking dish from the oven, and top with the fresh lemon juice. Serve hot and enjoy!
