Welcome to the cozy embrace of autumn with this Savory Autumn Squash Casserole. It's a delightful blend of sweet and savory flavors, perfect for those crisp fall evenings when you're craving something hearty and comforting. Let's dive into this seasonal favorite!
Butternut squash is the star of this dish, offering a sweet, nutty flavor and a creamy texture once cooked. Sour cream adds tanginess and creaminess, balancing the sweetness of the squash. Parmesan cheese provides a salty, umami kick that enriches the overall flavor profile. Unsalted butter keeps the casserole moist and adds richness. Ritz crackers and pecans create a crunchy, buttery topping that contrasts beautifully with the creamy filling. A touch of ground cinnamon and nutmeg adds warmth and a hint of spice, enhancing the autumnal vibe. Finish with salt and pepper to taste for seasoning.
First things first, preheat your oven to 375°F (190°C) and grease a 9x13 inch baking dish to prevent sticking. In a large skillet over medium heat, pour in a tablespoon of olive oil. Once it's shimmering, toss in the chopped onion and sauté until it turns translucent, releasing its sweet aroma.
Add the cubed butternut squash to the skillet. Cook for about 8-10 minutes, stirring occasionally, until the squash is slightly tender. You want it soft enough to bite into, but not mushy, as it will cook further in the oven.
While the squash is cooking, grab a large bowl and combine the sour cream, Parmesan cheese, melted butter, cinnamon, nutmeg, salt, and pepper. Mix until everything is well incorporated, creating a creamy, seasoned base for your casserole.
Once the squash and onions are ready, fold them into the sour cream mixture. Make sure the squash is evenly coated, then pour everything into your prepared baking dish. Spread it out so it's nice and even.
In a separate bowl, mix the crushed Ritz crackers with the chopped pecans. This will be your deliciously crunchy topping. Sprinkle the mixture evenly over the top of the casserole, covering it completely.
Pop the casserole into your preheated oven and bake for 25-30 minutes. You'll know it's done when the top is golden brown and the casserole is bubbling around the edges. Let it cool for a few minutes before serving, allowing the flavors to meld together.
This Savory Autumn Squash Casserole pairs beautifully with roasted chicken or turkey, making it a fantastic side dish for Thanksgiving or any fall gathering. For a vegetarian meal, serve it alongside a hearty green salad with a tangy vinaigrette to cut through the richness of the casserole.
