How to Make Chicken Zucchini Casserole

Step 1: Prepare the Ingredients

Start by slicing the zucchini thinly and dicing the onion and garlic. Cut the chicken breast into bite-sized pieces to ensure even cooking and blending of flavors in the casserole.

Step 2: Sauté Chicken and Vegetables

Heat olive oil in a large skillet over medium heat. Add the chicken pieces and cook until they start to brown. Toss in the onions and garlic, cooking until fragrant and translucent. This step builds a savory base that makes your casserole shine.

Step 3: Combine Sauce Ingredients

In a separate bowl, mix vegetarian Worcestershire sauce, apple cider vinegar, salt, pepper, and your natural gelling agent. Stir well to combine the flavors that will bind and enhance the casserole’s texture and taste.

Step 4: Layer the Casserole

In a baking dish, arrange half of the sliced zucchini as the first layer, then add the cooked chicken mixture on top. Pour half of your sauce mixture over the chicken, then repeat with the remaining zucchini and sauce.

Step 5: Add Plant-Based Cheese and Bake

Sprinkle the plant-based cheese generously over the top layer. Bake the casserole in a preheated oven at 375°F (190°C) for about 25 to 30 minutes until bubbly and golden on top.

Pro Tips for Making Chicken Zucchini Casserole

Avoid sogginess: Salt the sliced zucchini and let it sit for 10 minutes to draw out excess moisture before assembling.
Even cooking: Cut chicken into uniform pieces for consistent cooking and texture.
Savory boost: Toast the natural gelling agent lightly before mixing to unlock its flavor and improve texture.
Cheese topping: Use shredded plant-based cheese that melts well for that perfect golden crust.
