3 cups fresh baby spinach, loosely packed If using frozen, thaw and squeeze out excess water.

½ cup Greek yogurt (plain) Provides creaminess without heavy cream.

¼ cup whole‑grain breadcrumbs Adds a light crust; omit for gluten‑free.

2 cloves garlic, minced Optional for extra aroma.

½ tsp smoked paprika Adds subtle warmth; omit if preferred.

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

Instructions

Prepare the chicken

Season cubed chicken with salt, pepper, and smoked paprika. Heat a drizzle of olive oil in a large skillet over medium‑high heat, then sear the chicken until lightly browned, about 4‑5 minutes. Transfer to a plate; it will finish cooking in the oven.

Pro Tip: Do not overcrowd the pan – work in batches for a golden crust.

Sauté aromatics & spinach

In the same skillet, add a little more oil if needed, then sauté minced garlic for 30 seconds. Add the fresh spinach, stirring until wilted, about 2 minutes. Remove from heat and set aside with the chicken.

Pro Tip: Fresh spinach reduces dramatically; no need to pre‑cook excess.

Mix the casserole base

In a large bowl combine the seared chicken, wilted spinach, Greek yogurt, half of the mozzarella, and a pinch of extra salt and pepper. Stir until evenly coated; the yogurt creates a light, tangy sauce that binds everything.

Pro Tip: Avoid over‑mixing to keep chicken pieces tender.

Assemble & bake

Spread the mixture into a greased 9‑inch baking dish. Sprinkle the remaining mozzarella and breadcrumbs evenly over the top. Bake in a preheated 375°F (190°C) oven for 20‑25 minutes, until the cheese is bubbly and the crust turns golden.

Pro Tip: If you like extra crispness, broil for the last 2 minutes.

Rest and serve

Allow the casserole to rest for 5 minutes after removal. This lets the sauce thicken slightly, making slicing easier. Serve warm with a simple side salad or steamed veggies for a complete meal.

Pro Tip: Garnish with fresh herbs like parsley for a pop of color.

Expert Tips

Tip #1: Pre‑cook the chicken

Searing the chicken first adds flavor and ensures it’s fully cooked, while still keeping it moist inside the casserole.

Tip #2: Use low‑fat dairy

Greek yogurt replaces heavy cream, cutting calories while adding a pleasant tang that balances the cheese.

Tip #3: Add a crunchy topping

A light sprinkle of breadcrumbs mixed with a drizzle of olive oil creates a golden crust without excess carbs.

Tip #4: Cool before refrigerating

Let leftovers reach room temperature before sealing; this prevents condensation and keeps the texture firm.

Storage & Variations

Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently in the oven or microwave. For a low‑carb twist, replace breadcrumbs with crushed pork rinds. Swap chicken for cooked shrimp or firm tofu to suit dietary preferences.

Frequently Asked Questions

Yes. Thaw the frozen spinach, squeeze out excess moisture, and add it directly to the mixing bowl. This saves prep time while still delivering the same nutrients.

Omit the breadcrumbs or replace them with almond flour or crushed pork rinds. The casserole will still have a pleasant crust without any wheat.

Assemble the casserole, cover tightly, and refrigerate up to 24 hours before baking. Add the breadcrumb topping just before baking to keep it crisp.
