Instructions
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.
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.
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.
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.
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.
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.
