4 cups fresh baby spinach, loosely packed If using frozen, thaw and squeeze excess water.
½ cup oat flour (or whole‑grain flour) Provides a subtle nutty flavor and thickens the sauce.
1 cup low‑sodium chicken broth Adds depth without extra salt.
¾ cup plain Greek yogurt Creates a creamy texture while boosting protein.
1 tsp garlic powder Optional fresh minced garlic works, too.
½ tsp smoked paprika Adds subtle warmth without heat.
Salt & pepper to taste Use sparingly for a clean‑eating profile.

Instructions

1

Prepare the chicken

Season the cubed chicken with garlic powder, smoked paprika, salt, and pepper. Heat a large skillet over medium‑high heat, add a drizzle of olive oil, and sear the chicken until lightly browned on all sides, about 5‑6 minutes. Transfer to a plate.

Pro Tip: Don’t overcrowd the pan; work in batches for a golden crust.
2

Build the sauce

In the same skillet, whisk oat flour into the remaining oil, cooking for 1 minute to eliminate raw taste. Gradually pour in the chicken broth, stirring constantly until smooth. Simmer 3‑4 minutes until the mixture thickens, then lower heat and fold in Greek yogurt.

Pro Tip: Temper the yogurt with a spoonful of hot sauce before adding to prevent curdling.
3

Combine vegetables

Add the fresh spinach to the sauce, stirring until wilted (about 2 minutes). If using frozen spinach, ensure it’s fully thawed and drained before mixing.

Pro Tip: Season with a pinch of nutmeg for an extra layer of flavor.
4

Assemble the casserole

Preheat oven to 375°F (190°C). In a large baking dish, spread the chicken pieces evenly, then pour the spinach‑sauce over the top, ensuring full coverage.

Pro Tip: Smooth the surface with a spatula for even baking.
5

Bake and serve

Cover the dish with foil and bake for 20 minutes. Remove foil and bake an additional 10‑12 minutes, until the top is lightly golden and the casserole bubbles. Let rest 5 minutes before portioning.

Pro Tip: A brief cool‑down helps the sauce set, making slices cleaner.

Expert Tips

Tip #1: Use a cast‑iron skillet

A well‑seasoned cast‑iron pan retains heat, giving the chicken a superior crust and ensuring an even sauce consistency.

Tip #2: Chill the casserole before reheating

Cooling the dish overnight lets flavors meld, and reheating gently preserves the creamy texture without drying out.

Tip #3: Add a crunchy topping

A sprinkle of toasted almond slivers or whole‑grain breadcrumbs during the last 5 minutes adds texture without excess calories.

Storage & Variations

Cool the casserole completely, then store in airtight containers for up to 4 days in the fridge. Freeze individual portions for up to 3 months; reheat covered to retain moisture. Swap chicken for firm tofu for a vegetarian version, or stir in roasted red peppers for extra sweetness.

Frequently Asked Questions

Yes. Thaw it completely, squeeze out excess moisture, and add it to the sauce. This prevents a watery casserole and maintains a creamy texture.

Use low‑sodium broth, limit added salt, and rely on herbs and spices for flavor. You can also substitute a splash of unsalted almond milk for part of the broth.

Substitute the Greek yogurt with a plant‑based yogurt (unsweetened) and ensure the broth is dairy‑free. The texture remains creamy and the flavor stays intact.

Serve with a simple quinoa pilaf, roasted sweet potatoes, or a crisp mixed greens salad dressed with lemon‑olive oil for a complete, balanced dinner.
