Ingredients for Creamy Butternut Squash Casserole
Here’s what you’ll need to make this delicious Creamy Butternut Squash Casserole:
2 medium butternut squash – Peeled, seeded, and cubed; the star of the dish with its sweet, nutty flavor and creamy texture once cooked.
5 tablespoons Crystal butter – Adds richness and flavor, crucial for that luscious creaminess throughout.
3 cloves garlic – Minced fresh for a depth of flavor that compliments the squash beautifully.
2 yellow onions – Chopped to add sweetness and aromatic undertones to the casserole base.
2 (9 ounce) packages frozen spinach – Thawed and drained; this brings in color, flavor, and nutrients, balancing the richness.
¼ teaspoon ground nutmeg – A pinch of this spice rounds out the flavors with warmth and depth.
1 cup gruyere or white cheddar cheese – Grated; ensures a melty, gooey top layer that’s hard to resist.
¾ cup parmesan cheese – Grated; this provides a slightly salty, nutty flavor that enhances the overall profile.
¾ cup Crystal heavy cream – For that dreamy, creamy sauce that ties everything together in a way that’s near-magical.
2 tablespoons extra-virgin olive oil – Perfect for roasting the squash, infusing it with deep flavor.
1½ cup panko bread crumbs – These create a crispy topping, offering great texture and crunch.
Kosher salt and freshly ground pepper – To taste, essential for bringing out the vibrant flavors of each ingredient.
How to Make Creamy Butternut Squash Casserole
Follow these simple steps to prepare this delicious Creamy Butternut Squash Casserole:
Step 1: Preheat the Oven
Begin by heating the oven to 400º F (200º C). This hot environment ensures that your vegetables roast beautifully while developing that sweet, caramelized flavor.
Step 2: Prepare and Roast the Squash
In a large bowl, toss the cubed butternut squash with olive oil, salt, and pepper. Spread the squash cubes in a single layer on a baking sheet. Roast for 20-25 minutes, or until tender, allowing the natural sweetness to shine. Once done, take it out of the oven and set aside.
Step 3: Sauté Aromatics
In a large skillet, melt 2 tablespoons of Crystal butter over medium-high heat. Sauté the chopped onions for about 8 minutes until they’re softened and translucent. Add the minced garlic and cook for another minute, seasoning with a touch of salt and pepper.
Step 4: Combine Ingredients
Reduce the heat to medium and add the thawed and drained spinach to the skillet, mixing it with the onions and garlic. Gradually stir in the heavy cream, a tablespoon at a time, allowing it to fully incorporate. Bring in the nutmeg and let it cook for another 5 minutes until the mixture thickens beautifully.
Step 5: Assemble the Casserole
Gently fold the roasted butternut squash into the creamy mixture in the skillet. Transfer everything into a 9×13-inch baking dish, sprinkling the grated gruyere and parmesan cheeses on top. Give it a light mix to ensure an even distribution of cheese throughout.
Step 6: Add Crunchy Topping
In a medium bowl, mix 3 tablespoons of melted butter with the panko bread crumbs. Sprinkle this irresistibly crunchy mixture evenly over the top of the casserole, ensuring a delightful texture contrast to every creamy bite.
Step 7: Bake and Serve
Pop the casserole in the oven and bake for 30-35 minutes, or until it’s all bubbly and golden on top. Once it’s ready, allow it to cool for about 5 minutes — if you can resist — before diving in.
This creamy butternut squash casserole makes for an elegant side dish at holiday dinners or a comforting main course during colder months. The rich layers of flavors and textures will be a bowl full of happiness, perfect for family gatherings or cozy nights in just waiting to be served. Enjoy!
