Preheat your oven to 350 and spray a 9x11 glass baking dish.

Cut your zucchinis lengthwise, and then chop those into thirds. Make sure you slice them them somewhat thinly so they cook evenly in the bake! Once sliced, put them in a medium sized bowl. Add in the olive oil, salt and pepper and gently mix until the zucchini pieces are all coated in the oil.

Get your marinara sauce ready. If it's been refrigerated, set it out 30 minutes prior to building the bake. If it’s store bought or you just made it, you don’t need to do anything.

Put about 1/3 cup marinara into the bottom of the dish and evenly spread it out. Next, add some sliced zucchini and evenly distribute so that the sauce is completely covered with zucchini. Next, add about a 1/4 cup of cheese and sprinkle on top of the zucchini. Repeat this assembly 3 more times.

On the last layer, you can use the extra sauce for the top and use any extra cheese to sprinkle on the top as well.

Throw it in the oven for 35-40 minutes; until the sauce is starting to bubble and the cheese is slightly brown.

Take it out and let cool for 5 minutes. I love to top it with fresh basil or parmesan cheese. In an airtight container, you can store in the fridge for up to 3 days or freeze for up to 2 months. Enjoy!:)
