1tspolive oil
1onionsliced
1cloveof garlicsliced very thin
1/4-1/2cupof Parmesan cheesegrated
½tspdried basil
2-3leavesof basilchopped for garnish
Instructions
Preheat the oven to 375 degrees. Coat a large and deep baking dish (I used a large corning ware casserole dish) with olive oil cooking spray.
Slice the zucchini, yellow squash, onion, and tomatoes into thick slices.
Heat the olive oil in a skillet over medium heat. Once the pan is hot add the onion slices and sauté for 15-20 minutes or until golden brown and caramelized- make sure you season with sea salt to taste. Add the garlic to the onions and sauté, stirring frequently for 60 seconds then remove from heat and let cool.
Layer the dish with first tomatoes then yellow squash, a bit of Parmesan then the layer of caramelized onions and garlic, then the zucchini, and finally the last layer of tomatoes. I seasoned each layer (except the onions) with a little bit of sea salt and pepper.
Top with the remaining Parmesan cheese and then sprinkle the dried basil on top and cover with a lid or tin foil.
Bake for 20-25 minutes. Remove the lid or tin foil and broil for 3-4 minutes or until golden brown and crispy on top. Let cool for a few minutes. Garnish with fresh basil. Enjoy.
