Take each zucchini half and carefully scoop out the center to create little boats, leaving about 1/4 inch thickness around the edges.

Heat olive oil in a skillet over medium heat. Add your minced garlic and chopped onion, cooking until they become fragrant and translucent, about 2 minutes.

Add the chopped mushrooms to the skillet and cook until they release their moisture and become tender, about 3-4 minutes. Then add the spinach and cook just until it wilts down, about 2 minutes more.

Remove the skillet from heat and stir in the ricotta, Parmesan, and red pepper flakes if using. Season the mixture with salt and pepper to your taste.
