this Recipe

Ingredients:

• Butternut Squash: 2 medium, about 4-5 pounds total, peeled, seeded, and cubed into 1-inch pieces
• Olive Oil: 3 tablespoons, extra virgin
• Salt: 1 teaspoon, plus more to taste
• Black Pepper: ½ teaspoon, freshly ground, plus more to taste
• Yellow Onion: 1 medium, chopped
• Garlic: 4 cloves, minced
• Fresh Sage: 2 tablespoons, chopped (or 2 teaspoons dried sage)
• Fresh Thyme: 1 tablespoon, chopped (or 1 teaspoon dried thyme)
• Vegetable Broth: ½ cup
• Heavy Cream: 1 cup
• Gruyere Cheese: 1 ½ cups, shredded
• Panko Bread Crumbs: 1 cup
• Butter: 4 tablespoons, melted
• Parmesan Cheese: ½ cup, grated
• Pecans: ½ cup, chopped (optional, for topping)

Preparing the Butternut Squash:

Okay, let’s get started! First things first, we need to tackle that butternut squash. I know, peeling and cubing it can seem daunting, but trust me, it’s worth it. Make sure you have a good, sharp vegetable peeler and a sturdy knife. Safety first!

1. Preheat the Oven: Preheat your oven to 400°F (200°C). This ensures the squash roasts evenly.
2. Prepare the Squash: Peel the butternut squash using a vegetable peeler. Then, cut it in half lengthwise. Scoop out the seeds and stringy bits with a spoon. Now, cut each half into 1-inch cubes. Try to keep the cubes relatively uniform in size so they cook at the same rate.
3. Season the Squash: In a large bowl, toss the cubed butternut squash with 3 tablespoons of olive oil, 1 teaspoon of salt, and ½ teaspoon of black pepper. Make sure every piece is coated nicely.
4. Roast the Squash: Spread the seasoned squash in a single layer on a large baking sheet. You might need two baking sheets to avoid overcrowding. Roast for 25-30 minutes, or until the squash is tender and slightly caramelized. I like to flip the squash halfway through to ensure even browning.

Sautéing the Aromatics:

While the squash is roasting, let’s get the aromatics ready. This step adds a ton of flavor to the casserole. The combination of onion, garlic, sage, and thyme is just heavenly!

1. Sauté the Onion: In a large skillet or Dutch oven, heat 1 tablespoon of olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Stir occasionally to prevent burning.
2. Add Garlic and Herbs: Add the minced garlic, chopped sage, and chopped thyme to the skillet. Cook for another minute or two, until fragrant. Be careful not to burn the garlic, as it can become bitter.
3. Deglaze the Pan: Pour in the ½ cup of vegetable broth and scrape up any browned bits from the bottom of the skillet. This adds extra flavor to the sauce. Let the broth simmer for a minute or two, until slightly reduced.

Creating the Creamy Sauce:

Now for the creamy, dreamy sauce that brings everything together. The heavy cream and Gruyere cheese create a rich and decadent base that perfectly complements the sweetness of the butternut squash.

1. Add Heavy Cream: Pour the 1 cup of heavy cream into the skillet with the onion, garlic, and herbs. Bring to a simmer, then reduce the heat to low and let it simmer for 5-7 minutes, or until the sauce has thickened slightly.
2. Incorporate the Gruyere: Remove the skillet from the heat and stir in 1 cup of the shredded Gruyere cheese until it’s melted and smooth. Reserve the remaining ½ cup of Gruyere for the topping.
3. Season to Taste: Taste the sauce and adjust the seasoning as needed. Add more salt and pepper to your liking. Remember, the cheese is already salty, so be careful not to over-salt.

Assembling the Casserole:

Time to put it all together! This is where the magic happens. Layering the roasted squash with the creamy sauce and topping it with a crispy breadcrumb mixture creates a symphony of textures and flavors.

1. Combine Squash and Sauce: Gently fold the roasted butternut squash into the creamy Gruyere sauce. Make sure the squash is evenly coated.
2. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish. Spread it out evenly.

Preparing the Breadcrumb Topping:

The breadcrumb topping is the crowning glory of this casserole. It adds a delightful crunch and a nutty, cheesy flavor that takes it to the next level. Don’t skip this step!

1. Melt the Butter: In a small bowl, melt the 4 tablespoons of butter. You can do this in the microwave or on the stovetop.
2. Combine Ingredients: Add the 1 cup of panko bread crumbs, ½ cup of grated Parmesan cheese, and the melted butter to the bowl. Mix well until the bread crumbs are evenly coated.
3. Add Pecans (Optional): If you’re using pecans, add the ½ cup of chopped pecans to the breadcrumb mixture and stir to combine.
4. Sprinkle the Topping: Sprinkle the breadcrumb mixture evenly over the butternut squash mixture in the baking dish. Then, sprinkle the remaining ½ cup of shredded Gruyere cheese over the breadcrumbs.

Baking the Casserole:

Almost there! Now it’s time to bake the casserole until it’s bubbly and golden brown. The aroma that fills your kitchen will be irresistible!

1. Bake: Bake in the preheated oven for 20-25 minutes, or until the topping is golden brown and the casserole is bubbly. Keep an eye on it to prevent the topping from burning. If it starts to brown too quickly, you can tent the baking dish with foil.
2. Let it Rest: Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to meld together and the casserole to set slightly.

This butternut squash casserole is delicious on its own, but it also pairs well with a variety of dishes. Here are a few serving suggestions:
