Instructions

Sauté Chicken

Heat olive oil in a large skillet over medium‑high heat. Add diced chicken, season with salt, pepper, and garlic powder. Cook 5‑6 minutes, stirring occasionally, until lightly browned but not fully cooked through. Transfer to a bowl.

Pro Tip: Avoid crowding the pan; work in batches for even browning.

Wilt the Spinach

In the same skillet, add a splash of broth and the chopped spinach. Cook, stirring, until wilted, about 2 minutes. If using frozen spinach, ensure it’s fully thawed and drained before adding.

Pro Tip: Add a pinch of nutmeg for a subtle warmth.

Combine Creamy Base

In a large mixing bowl, whisk together Greek yogurt, remaining chicken broth, and half of the cheddar cheese. Stir in the sautéed chicken and wilted spinach until evenly coated.

Pro Tip: Temper the yogurt with a little hot broth first to prevent curdling.

Assemble the Casserole

Transfer the mixture to a greased 9‑x‑13‑inch baking dish. Sprinkle the remaining cheddar and the mozzarella evenly over the top, creating a golden crust.

Pro Tip: Add a thin layer of breadcrumbs for extra crunch if desired.

Bake to Perfection

Bake in a pre‑heated 375°F (190°C) oven for 20‑25 minutes, or until the cheese is bubbling and lightly browned. Let rest 5 minutes before serving to set.

Pro Tip: If the top browns too quickly, cover loosely with foil.

Expert Tips

Tip #1: Use Fresh Herbs

A tablespoon of chopped fresh parsley or basil added before serving brightens flavor and adds a pop of color without extra calories.

Tip #2: Pre‑Cook the Chicken

If you’re short on time, use pre‑cooked rotisserie chicken. Shred it and skip the sauté step, reducing total prep by 10 minutes.

Tip #3: Add a Crunchy Topping

Mix ¼ cup toasted slivered almonds or crushed pork rinds into the cheese layer for a satisfying texture contrast.

Storage & Variations

Refrigerate leftovers in an airtight container for up to 4 days; reheat gently in the oven or microwave. For a low‑carb twist, replace the broth with cauliflower puree and add grated Parmesan. Swap chicken for cooked shrimp or firm tofu to create a seafood or vegetarian version while keeping the protein high.

Substitute with the same amount of low‑fat cottage cheese blended smooth, or use a dairy‑free yogurt alternative. Both will keep the creamy texture while maintaining protein levels.
