How to Make Zucchini Alfredo Casserole with Chicken

Preheat your oven to 200°C (400°F) and gently grease a 9×13 inch baking dish, ensuring it’s ready for our delicious layers!
Slice the zucchini into thin ribbons. Sprinkle with salt and let them sit for about 10-15 minutes. This helps to draw out the moisture—then pat them dry.
Sauté minced garlic in olive oil or butter over medium heat for about 2 minutes, until fragrant. Whisk in heavy cream and cream cheese until smooth, about 3-5 minutes.
Stir in grated Parmesan, black pepper, Italian seasoning, and any optional red pepper flakes. Simmer briefly to thicken, letting those flavors meld beautifully.
Combine the cooked chicken with a few spoonfuls of the creamy sauce and fold in any optional add-ins, mixing until everything is well-coated.
Layer your dish: spread some sauce at the bottom, then a layer of zucchini ribbons, followed by chicken, more sauce, and shredded cheese. Repeat this process twice, finishing with zucchini and sauce on top.
Cover the casserole dish with foil; bake for 20 minutes. Then, uncover and continue baking for an additional 10-15 minutes until the top is golden and bubbling.
Rest the casserole for 10 minutes before slicing and serving. Garnish with chopped parsley or basil for a fresh touch!

Optional: Add a sprinkle of extra Parmesan on top for a cheesy finish!
