Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
Step 2: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for 5-7 minutes until softened and translucent.
Step 3: Add the minced garlic to the skillet and cook for another minute until fragrant. Do not let it burn.
Step 4: Add the thinly sliced zucchini to the skillet. Cook for 5-8 minutes, stirring occasionally, until the zucchini starts to soften slightly but still holds its shape. This pre-cooking step is crucial for a tender zuchinis recipe.
Step 5: Pour in the vegetable broth and heavy cream. Stir in the dried Italian herbs, salt, and black pepper. Bring to a gentle simmer and cook for 2-3 minutes, allowing the flavors to meld.
Step 6: Transfer half of the zucchini mixture to the prepared baking dish, spreading it evenly.
Step 7: Sprinkle half of the mozzarella and Parmesan cheeses over the zucchini layer.
Step 8: Top with the remaining zucchini mixture, spreading it out. This zuchinis recipe layering ensures even cheesy goodness.
Step 9: Sprinkle the remaining mozzarella and Parmesan cheeses over the top. If desired, scatter breadcrumbs for extra crispiness.
Step 10: Bake for 25-30 minutes, or until the zuchinis recipe is bubbly and the cheese is golden brown and melted.
Step 11: Remove from oven and let stand for 5-10 minutes before serving. This allows the bake to set slightly, making it easier to serve. Enjoy your delicious zuchinis recipe!
