WHY I LOVE THIS RECIPE?
- Relives the nostalgia of cozy family dinners on chilly autumn evenings.
- Joy in transforming leftovers into something fresh and delicious.
- My pride in using seasonal, earthy flavors like sage and pumpkin.
- Relief from stressful meal planning—this dish comes together quickly.

AVOID MY DISASTER (You’re Welcome)
- FORGOT to drain the excess liquid—resulted in a soggy casserole. Drain veggies well next time.
- DUMPED in too much cheese—made the dish greasy and heavy. Use half as much cheese.
- OVER‑TORCHED the top—burnt bits with a bitter flavor. Keep a close eye during broiling.
- MISSED the seasoning—dish was bland. Always taste and add herbs before baking.
QUICK FIXES THAT SAVE YOUR DAY
- When too watery—splash in a teaspoon of cornstarch mixed with cold water.
- Patience! When cheese isn’t melting—shield with foil and bake a few more minutes.
- When flavor’s lackluster—sprinkle fresh herbs right before serving for a burst of aroma.
- Spill over during baking—place a baking sheet underneath to catch drips.
- When vegetables are undercooked—cover with foil and bake five more minutes.
This casserole’s seasonal charm comes from its honest, rustic flavors that evoke the heart of fall. It’s perfect for busy weeknights when you want something hearty but straightforward. Plus, the lingering smell of roasted herbs and browned cheese makes your home feel inviting and full of warmth.

Easy Fall Chicken Casserole
Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C) and lightly grease a baking dish with butter.
- In a mixing bowl, combine shredded cooked chicken, diced squash, chopped kale, minced garlic, and chopped sage. Toss everything together to evenly distribute the ingredients.
- Drizzle the olive oil over the mixture, then add salt and black pepper. Mix again until all ingredients are coated and well combined.
- Transfer the mixture into the prepared baking dish, spreading it out into an even layer. Sprinkle shredded cheese over the top, covering everything generously.
- Place small pats of butter on top of the cheese, then put the casserole into the oven. Bake for about 30 to 35 minutes, or until bubbling and golden around the edges.
- Once baked, remove from the oven and let sit for a few minutes. The casserole will set slightly and develop a crispy top layer.
- Slice into portions and serve hot, enjoying the hearty, cheesy, seasonal flavors with a rustic appearance.
