This Baked Harvest Chicken and Rice Casserole with Butternut Squash is a cozy one-dish meal packed with classic autumn flavors.
Tender chicken, rice, sweet butternut squash, dried cranberries, onion, garlic, and fresh herbs bake together in a savory broth until the rice is fluffy and the chicken is juicy.
The combination of savory chicken, naturally sweet squash, and tart cranberries makes this casserole especially satisfying during cooler weather.
It is also an easy choice for busy family dinners because most of the cooking happens right in the oven.
Why You Will Love This Recipe
This casserole gives you protein, vegetables, and rice in one baking dish, which makes dinner simple and practical.
The butternut squash becomes tender and slightly sweet as it bakes, while thyme and sage bring classic fall flavor.
Dried cranberries provide small bursts of sweetness that balance the savory chicken and broth.
The recipe is also easy to prepare ahead of time, making it useful for meal prep or busy weeknights.
And because everything bakes together, there is much less cleanup afterward.

🍳 Step-by-Step Masterclass Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a large casserole dish, approximately 9 × 13 inches.
Step 2: Prepare the Chicken
Pat the chicken dry with paper towels.
Cut it into large bite-size pieces and season with salt, black pepper, smoked paprika, and garlic powder.
Heat 1 tablespoon of olive oil in a skillet over medium-high heat.
Add the chicken and cook for approximately 3–4 minutes, just until lightly browned on the outside.
The chicken does not need to be fully cooked yet.
Transfer it to a plate.
Masterclass Tip: Browning the chicken first adds extra flavor and helps keep the texture more appealing after baking.
Step 3: Sauté the Onion and Garlic
In the same skillet, add the remaining olive oil and butter.
Add the diced onion and cook for 2–3 minutes until softened.
Add the minced garlic and cook for another 30 seconds.
Stir in the thyme and sage.
Step 4: Add the Rice
Add the uncooked rice to the skillet.
Stir for about 1 minute so the grains become lightly coated with the butter, oil, and herbs.
Masterclass Tip: Toasting the rice briefly helps the grains stay more separate during baking.
Step 5: Assemble the Casserole
Transfer the rice mixture to the prepared baking dish.
Add the butternut squash cubes and dried cranberries.
Pour in the chicken broth and heavy cream.
Stir gently so everything is evenly distributed.
Arrange the browned chicken pieces across the top.
Step 6: Cover and Bake
Cover the baking dish tightly with aluminum foil.
Bake for approximately 35 minutes.
Keeping the dish covered traps steam inside and allows the rice to cook evenly.
Step 7: Check the Rice
Carefully remove the foil.
Check whether most of the liquid has been absorbed and whether the rice is almost tender.
If the rice still feels firm, cover again and bake for another 5–10 minutes.
Step 8: Add the Parmesan
Once the rice is nearly cooked, sprinkle the Parmesan evenly over the casserole.
Return the dish to the oven uncovered.
Bake for another 10–15 minutes, until the chicken is fully cooked, the squash is tender, and the top is lightly golden.
The chicken should reach an internal temperature of at least 165°F (74°C).
Step 9: Rest Before Serving
Remove the casserole from the oven and let it rest for approximately 5–10 minutes.
This short resting period allows the remaining moisture to absorb into the rice.
Masterclass Tip: Don’t stir aggressively as soon as the casserole comes out of the oven. Letting it rest helps keep the rice fluffy instead of sticky.
Step 10: Finish and Serve
Fluff the rice gently with a fork.
Add toasted pecans if using.
Finish with fresh thyme or parsley and a little cracked black pepper.
Serve warm with a good mix of chicken, rice, squash, and cranberries in every portion.
🔒 Storage & Reheating Tips
Refrigerator: Store cooled leftovers in an airtight container for up to 3–4 days.
Meal prep: Divide the casserole into individual containers after it has cooled. It reheats well for easy lunches or dinners.
Oven reheating: Cover the casserole with foil and reheat at 350°F (175°C) for about 15–20 minutes. Add a small splash of chicken broth if the rice looks dry.
Microwave: Add a teaspoon or two of water or broth to an individual portion, cover loosely, and microwave until thoroughly hot.
Freezer: Freeze cooked portions in airtight freezer-safe containers for up to 2 months.
Allow frozen portions to thaw overnight in the refrigerator before reheating for the best texture.
If using pecans, add them after reheating rather than before freezing so they remain crunchy.
