3 cups fresh spinach, roughly chopped If using frozen, thaw and squeeze excess water.

1 ½ cups low‑fat Greek yogurt Provides creaminess without extra fat.

1 cup shredded mozzarella cheese Low‑moisture keeps the dish from getting watery.

3 cloves garlic, minced Adds aromatic depth.

½ cup low‑sodium chicken broth Enhances moisture without excess salt.

¼ cup grated Parmesan cheese Adds a salty finish.

1 tbsp olive oil For browning the chicken.

Salt and freshly ground black pepper, to taste Season in layers for best flavor.

Instructions

Brown the chicken

Heat olive oil in a large skillet over medium‑high heat. Add cubed chicken, season with salt and pepper, and sauté until lightly golden, about 5‑6 minutes. Transfer to a bowl; it will finish cooking in the oven.

Pro Tip: Do not overcrowd the pan; work in batches for a better sear.

Sauté garlic and spinach

In the same skillet, reduce heat to medium, add minced garlic, and cook 30 seconds until fragrant. Add spinach, stirring until wilted, about 2 minutes. Remove from heat and set aside with the chicken.

Mix the creamy base

In a large bowl combine Greek yogurt, chicken broth, half of the mozzarella, Parmesan, and a pinch of pepper. Whisk until smooth, then fold in the browned chicken and sautéed spinach.

Bake the casserole

Transfer the mixture to a greased 9‑inch baking dish. Sprinkle the remaining mozzarella on top. Bake in a pre‑heated 375°F (190°C) oven for 20‑25 minutes, until the cheese is bubbly and golden.

Rest and serve

Allow the casserole to rest 5 minutes before cutting. This helps the sauce set and makes serving easier. Garnish with a sprinkle of fresh parsley if desired.

Expert Tips

Tip #1: Use full‑fat Greek yogurt

It yields a richer texture while still keeping the dish lower in saturated fat than traditional cream.

Tip #2: Pre‑cook the spinach

If using fresh, sauté quickly and squeeze out moisture; excess water can make the casserole soggy.

Tip #3: Let it rest

A 5‑minute rest after baking lets the sauce thicken, making each slice neat and creamy.

Storage & Variations

Cool the casserole completely, then refrigerate in an airtight container for up to 3 days. Reheat gently in the oven or microwave. For a low‑carb twist, replace the mozzarella with a blend of cheddar and cream cheese, or add roasted cauliflower florets for extra veg.
