Ingredients for Creamy Butternut Squash Casserole

Here’s what you’ll need to make this delicious Creamy Butternut Squash Casserole:

5 tablespoons Crystal butter – this adds richness and depth of flavor to your casserole.

3 cloves garlic – minced for that aromatic kick that we all love.

2 yellow onions – chopped to provide sweetness and a flavor backbone.

2 (9 ounce) packages frozen spinach – thawed and drained for vibrant color and nutrition.

¼ teaspoon ground nutmeg – just a pinch helps to enhance the flavors of the squash and cream.

1 cup gruyere or white cheddar cheese – grated for a luxurious, gooey texture that pulls every bite together.

¾ cup parmesan cheese – grated to add a sharp touch that contrasts beautifully with the cream.

¾ cup Crystal heavy cream – this is where the magic happens, adding creaminess to the casserole.

2 tablespoons extra-virgin olive oil – for roasting those squash cubes to perfection.

1½ cup panko bread crumbs – to create a delightful crunchy topping that elevates the dish.

Kosher salt and freshly ground pepper – to taste, essential seasoning that brings all flavors alive.

How to Make Creamy Butternut Squash Casserole

Follow these simple steps to prepare this delicious Creamy Butternut Squash Casserole:

Step 1: Preheat the Oven
Start by preheating your oven to 400º F (204º C). This temperature will roast the butternut squash beautifully and get your casserole bubbly.

Step 2: Prepare the Butternut Squash
In a large bowl, combine the cubed squash with extra-virgin olive oil, seasoning it generously with kosher salt and freshly ground pepper. Spread the squash cubes in a single layer on a baking sheet. Roast for 20-25 minutes until tender and slightly caramelized, filling your kitchen with an irresistible aroma.

Step 3: Sauté the Onions and Garlic
In a large skillet, melt 2 tablespoons of Crystal butter over medium-high heat. Add the chopped onions and sauté for about 8 minutes or until they are translucent and softened. Toss in the minced garlic, cooking for an additional minute until fragrant; be careful not to burn it.

Step 4: Mix in the Spinach and Cream
Lower the heat to medium and incorporate the thawed, drained spinach. Slowly stir in Crystal heavy cream, one tablespoon at a time, until fully blended. Sprinkle in the ground nutmeg, mixing well, and continue cooking for about 5 minutes or until the mixture thickens to a creamy consistency.

Step 5: Combine and Layer the Ingredients
Gently fold in the roasted butternut squash into the creamy spinach mixture. Transfer this heavenly concoction into a 9×13-inch baking dish. Top with both the grated gruyere and parmesan cheese, mixing gently to combine.

Step 6: Add the Crunchy Topping and Bake
In a separate bowl, mix 3 tablespoons of melted butter with the panko bread crumbs. Sprinkle evenly over your cheesy casserole. Bake in the preheated oven for 30–35 minutes or until the casserole is bubbly and the top is golden brown. You might want to do a little happy dance while it’s baking; you’ve earned it.

Once done, let your Creamy Butternut Squash Casserole cool for about 5 minutes—if you can resist the aroma long enough. Serve it alongside a vibrant salad or as a side dish to a roast and watch everyone come running to the table. Enjoy every rich, cheesy, and cozy bite of this delightful dish that feels like home.
