# Step-by-Step Instructions:
01 - Preheat oven to 375°F. Grease a deep 9x13-inch casserole dish with butter or nonstick spray.
02 - Heat olive oil in a skillet over medium heat. Add minced garlic, red onion, and red bell pepper. Sauté for 3 minutes until vegetables begin to soften. Stir in smoked paprika and thyme, then remove skillet from heat.
03 - Arrange sweet potato slices in a single layer at the bottom of the casserole dish. Top with half the sautéed vegetable mixture and a portion of baby spinach leaves. Layer zucchini slices next, followed by the remaining vegetable mixture and remaining spinach.
04 - In a large mixing bowl, whisk together ricotta cheese, grated Gruyère, grated Parmesan, egg yolks, milk, salt, white pepper, and nutmeg until smooth and homogeneous.
05 - In a separate clean bowl, whisk egg whites until stiff peaks form. Carefully fold the egg whites into the cheese mixture, maintaining as much volume as possible for an airy texture.
06 - Pour the cheese soufflé mixture evenly over the layered vegetables. In another bowl, combine panko breadcrumbs, melted unsalted butter, and chopped fresh parsley. Sprinkle topping uniformly across the surface.
07 - Bake uncovered for 40 to 45 minutes or until the topping is golden and the soufflé layer has risen. Remove from oven and let rest for 10 minutes to allow structure to set before serving.
