1Preheat your oven to 375°F (190°C).
Slice the zucchinis into 1/4-inch thick rounds.
In a large skillet, heat the olive oil and butter over medium heat.
Add the zucchini slices to the skillet and sauté for about 5 minutes, or until they start to soften.
Season the zucchini with salt and black pepper, stirring to combine.
Transfer the sautéed zucchini to a baking dish, spreading them out evenly.
Sprinkle the grated Parmesan cheese evenly over the zucchini.
Bake in the preheated oven for 20-25 minutes, or until the cheese is golden brown and bubbly.
Remove from the oven and let it cool for a few minutes before serving.
Enjoy your delicious Zucchini Parmesan Bake!
