How to Make Harvest Butternut & Rice Casserole

Preheat oven: Preheat your oven to 400°F (200°C). Meanwhile, toss 3 cups of cubed butternut squash with 1 tablespoon olive oil, salt, and pepper until each piece is evenly coated.
Roast squash: Arrange squash in a single layer on a parchment-lined baking sheet. Roast for 25–30 minutes, turning halfway through, until edges are golden brown and the flesh feels tender when pierced.
Sauté aromatics: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add finely chopped onion and minced garlic, sautéing for 4–5 minutes until fragrant and the onion turns translucent.
Toast rice: Stir in 1½ cups long-grain white rice, tossing for 2 minutes so each grain is coated in the flavorful oil and takes on a slightly toasted hue.
Add liquids: Pour in 2 cups vegetable broth and ½ cup heavy cream. Add fresh thyme leaves, salt, and pepper. Bring mixture to a gentle simmer, stirring occasionally.
Simmer rice: Cover skillet, reduce heat to low, and let rice cook for 18–20 minutes. Remove lid and check that the rice is tender and most liquid has been absorbed.
Combine squash and rice: Gently fold roasted butternut squash into the rice, stirring just enough to distribute the vibrant orange cubes evenly without mashing their shape.
Bake casserole: Transfer the mixture to a greased 9×13-inch baking dish. Bake at 375°F (190°C) for 15 minutes, until edges bubble and the top turns lightly golden.

Optional: Sprinkle chopped toasted pecans or grated Parmesan for crunchy, savory finish.

Variations & Substitutions for Harvest Butternut & Rice Casserole

Feel free to explore these delightful twists that can elevate your casserole to new heights!

Gluten-Free: Use quinoa or brown rice instead of white rice for a hearty, gluten-free option. Both alternatives add unique textures and flavors that complement the squash beautifully.
Vegan: Substitute heavy cream with coconut milk and use vegetable broth made from scratch. This version is not only dairy-free but also infuses a lovely richness that harmonizes with the butternut.
Spicy Kick: Add a pinch of cayenne pepper or diced jalapeños to introduce a warm heat that contrasts deliciously with the natural sweetness of the squash. Just a hint will do the trick without overwhelming the dish.
Cheesy Delight: Incorporate a blend of shredded Gruyère or sharp Cheddar cheese into the rice mixture before baking. The gooey, melted goodness will add a comforting layer of flavor that’s totally irresistible.
Herbaceous Twist: Mix in fresh rosemary or sage alongside the thyme for a more aromatic profile. Both herbs deepen the dish’s seasonal essence, perfectly complementing the butternut squash.
Crunchy Topping: Swap pecans for crushed French fried onions for a crispy topping that adds a delightful crunch with each bite. These savory bits will provide an appealing contrast to the creamy casserole beneath.
Nut-Free Option: If you’re avoiding nuts, replace them with sunflower seeds for a similar crunch without any allergen concerns. Lightly toast the seeds to enhance their flavor in the casserole.

Harvest Butternut & Rice Casserole Recipe FAQs

How do I know if my butternut squash is ripe and ready for the casserole?
Look for a squash with a hard, matte skin that’s a deep tan color without any dark spots or blemishes. A ripe butternut squash feels heavy for its size and has a slightly sweet aroma near the stem. Avoid any with soft spots, cracks, or shriveled areas.

What’s the best way to store leftover Harvest Butternut & Rice Casserole?
Store leftovers in an airtight container once cooled to room temperature. Keep it refrigerated for up to 3 to 4 days to maintain freshness and that creamy texture. Reheat gently to avoid drying out the dish.

Can I freeze this casserole, and how should I do it?
Absolutely! Freezing is a great way to save this comforting casserole. Portion it into individual servings and wrap each tightly in plastic wrap or aluminum foil. Then place them in a freezer-safe container or bag. It will keep beautifully for up to 3 months. When ready to eat, thaw overnight in the fridge and bake at 350°F (175°C) for about 20–25 minutes until warmed through.

What if my rice turns out too mushy or too firm?
If your rice is mushy, it likely absorbed too much liquid or cooked too long—reduce broth slightly next time or shorten simmering time by a few minutes. If it’s too firm, add a splash more broth, cover, and cook a bit longer on low heat. And don’t forget to toast the rice before cooking; it helps keep grains separate and fluffy.

Is this casserole safe for pets or those with food allergies?
While the main ingredients are wholesome, this recipe contains dairy (heavy cream) and nuts if you add optional toppings, which some pets and allergy sufferers may need to avoid. Always keep casseroles with dairy, nuts, garlic, and onions away from pets as they can be harmful. For allergy-friendly modifications, you might substitute cream with coconut milk and skip nuts.
