Step-by-step Instructions
- Preheat and prep: Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish.
- Sauté aromatics: Heat olive oil or butter in a skillet over medium heat. Add chopped onion and cook until translucent, about 4 minutes. Stir in garlic and cook 30 seconds.
- Make the sauce: Sprinkle the flour over the onions and stir for a minute. Slowly whisk in chicken broth, scraping any browned bits. Add heavy cream, sour cream, Dijon mustard, nutmeg, salt, and pepper. Simmer until the sauce thickens, about 3–5 minutes.
- Combine chicken and spinach: Stir in shredded chicken and spinach until spinach wilts and everything is evenly coated. Remove from heat and fold in 1 cup of shredded cheese.
- Assemble: Pour the mixture into the prepared baking dish. Sprinkle the remaining cheese and Parmesan evenly on top. Add breadcrumbs for a crunchy finish.
- Bake: Bake for 20–25 minutes, until the casserole is bubbling and the topping is golden. For extra color, broil 1–2 minutes more—watch carefully.
- Rest and serve: Let rest for 5–10 minutes before serving so the casserole sets. Garnish with fresh herbs.

Tips for Success
- Use cooked chicken that’s moist — rotisserie chicken works well for busy evenings.
- If using frozen spinach, squeeze out as much liquid as possible so the casserole isn’t watery.
- Don’t skip the flour step; it stabilizes the sauce so the casserole isn’t runny.
- For even melting, shred your cheese rather than using pre-grated varieties.
- Let the casserole rest before scooping; it will hold together better and slice nicely.

Possible Variations
- Gluten-free: Swap all-purpose flour for a 1:1 gluten-free blend and use gluten-free breadcrumbs for the topping.
- Streusel topping: Mix panko with melted butter, a pinch of smoked paprika, and grated Parmesan for an indulgent streusel-style crust.
- Add-ins: Stir in roasted mushrooms, sun-dried tomatoes, or artichoke hearts for more depth.
- Egg-topped bake: For a brunch version, crack a few eggs on top in the last 8–10 minutes of baking and finish until just set, echoing elements from our creamy spinach and eggs variation.
Storage Recommendations
- Refrigerate: Cool the casserole completely, cover airtight, and refrigerate for up to 3–4 days.
- Reheat: Warm individual portions in the microwave for 1–2 minutes or reheat the whole dish in a 350°F (175°C) oven until warmed through.
- Freeze: Assemble the casserole but don’t bake. Cover tightly and freeze for up to 3 months. Thaw overnight in the refrigerator and bake as directed (you may need an extra 10–15 minutes).
Label your container with the date so you can enjoy this comforting dish all season long.
