Ingredients for Autumn Harvest Squash Casserole

Butternut squash brings a natural sweetness and a creamy texture when roasted. It's the heart of this dish, providing a cozy, autumnal flavor. Quinoa adds a nutty taste and is a great source of protein, making the casserole hearty and satisfying. Olive oil is essential for roasting the squash and gives a rich flavor to the sautéed onions and garlic.

Salt and black pepper are simple yet essential seasonings that enhance the natural flavors of the ingredients. Parmesan cheese provides a savory, umami kick, while fresh sage leaves offer an aromatic herbal note that pairs beautifully with squash.

Vegetable broth adds depth and moisture to the quinoa, ensuring it cooks perfectly. Yellow onion and garlic are the flavorful base, giving the dish an inviting aroma. Walnuts add a satisfying crunch, and dried cranberries bring a pop of sweetness that complements the savory elements. Finally, a touch of nutmeg and a squeeze of lemon juice finish the dish with warmth and brightness.

Autumn Harvest Squash Casserole Recipe Walkthrough

Start by preheating your oven to 375°F. This gives your butternut squash the perfect environment to roast to tender perfection. While the oven is warming up, toss your cubed squash with a tablespoon of olive oil, half a teaspoon of salt, and a quarter teaspoon of black pepper. Spread the seasoned squash evenly on a baking sheet and pop it in the oven for about 25 minutes. You'll know it's done when it's fork-tender and slightly caramelized.

While the squash is roasting, grab a large pot and heat the remaining tablespoon of olive oil over medium heat. Add your diced onion and minced garlic, stirring occasionally until they turn translucent and fragrant. This usually takes about five minutes. Once the onions and garlic are ready, stir in the quinoa, fresh sage leaves, and a pinch of nutmeg. Let these flavors meld for about two minutes.

Pour in the vegetable broth, bring everything to a boil, and then reduce the heat to a simmer. Cover the pot and let it cook for 15 minutes, or until the quinoa has absorbed all the liquid and is nice and fluffy. By now, your roasted squash should be ready, so take it out of the oven and set it aside.

In a large mixing bowl, combine the roasted butternut squash with the cooked quinoa mixture. Add in the grated Parmesan cheese, chopped walnuts, and dried cranberries. Mix everything gently so that all the ingredients are evenly distributed. Transfer this hearty mixture into a greased casserole dish, spreading it evenly.

Bake the casserole for another 20 minutes. This will allow the flavors to meld together beautifully. Before serving, drizzle with a bit of lemon juice for a bright, fresh finish.
