How to Make Chicken Zucchini Casserole

Step 1: Prepare the Ingredients

Start by slicing the zucchini into thin rounds. Dice the onion and mince the garlic cloves. Cut the chicken breasts into bite-sized pieces for even cooking and better texture in the casserole.

Step 2: Sauté Aromatics and Chicken

Heat olive oil in a large skillet over medium heat. Add the onions and garlic, cooking until translucent and fragrant. Toss in the chicken pieces, seasoning with salt and pepper, and cook until lightly browned and nearly cooked through.

Step 3: Combine with Zucchini and Sauce

Transfer the chicken and aromatics to a mixing bowl. Add the zucchini slices, vegetarian Worcestershire sauce, apple cider vinegar (natural), freshly chopped herbs, and a touch of the natural gelling agent. Mix everything well to coat the veggies and chicken evenly.

Step 4: Assemble and Bake

Preheat your oven to 375°F (190°C). Spread the mixture into a casserole dish, then sprinkle the plant-based cheese (plant-based) generously on top. Bake uncovered for 25 to 30 minutes, or until the zucchini is tender and the cheese topping is melted and lightly golden.

Step 5: Rest and Serve

Once out of the oven, let the casserole rest for 5 minutes to set the flavors. This also helps the casserole hold together when serving.

Pro Tips for Making Chicken Zucchini Casserole

Even slicing: Slice zucchini uniformly so it cooks evenly without becoming mushy.
Drain excess moisture: If zucchini releases too much water, lightly salt it beforehand and pat dry to prevent a soggy casserole.
Pre-cook chicken: Searing chicken first locks in juices and adds flavor.
Herb timing: Add fresh herbs towards the end of the mixing process to keep their bright flavor intact.
Cheese layering: For extra cheesiness, layer some plant-based cheese (plant-based) within the casserole as well as on top.

How to Serve Chicken Zucchini Casserole

Garnishes

Sprinkle chopped fresh parsley or basil over the top just before serving for a pop of color and fresh herbal aroma. Toasted pine nuts or slivered almonds also add a pleasing crunch as a garnish.

Side Dishes

This casserole pairs beautifully with a simple green salad tossed in lemon vinaigrette or a side of roasted garlic potatoes to round out the meal with satisfying textures.

Creative Ways to Present

Serve the Chicken Zucchini Casserole in individual ramekins for an elegant touch during dinner parties or as hearty meal prep containers for quick weekday lunches.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Chicken Zucchini Casserole covered in the refrigerator for up to 3 days. This dish reheats well and maintains great flavor after a night in the fridge.

Freezing

To freeze, cool the casserole completely before transferring it to an airtight container. Freeze for up to 2 months and thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through, or microwave individual portions for a quick meal fix. Adding a sprinkle of plant-based cheese (plant-based) on top before reheating can freshen up the cheesy texture.
