What Ingredients You Will Need

This creamy butternut squash casserole with sage uses simple, wholesome ingredients to create bold, comforting flavors without the hassle.

• Butternut squash: Peeled, seeded, and diced into 1-inch cubes (fresh is best, but frozen works in a pinch).
• Olive oil: For roasting the squash and adding richness.
• Fresh sage: Chopped finely for that signature earthy flavor.
• Heavy cream: The base for the creamy sauce—use dairy-free alternatives like coconut cream if needed.
• Nutmeg: Just a pinch adds warmth and depth to the dish.
• Salt & pepper: To season the squash and enhance the overall flavor.
• Bread crumbs: For the topping—use panko for extra crunch or gluten-free crumbs if necessary.
• Parmesan cheese: Grated for a nutty, savory addition to the topping.
• Butter: Melted for mixing with the breadcrumbs.

Feel free to adjust the ingredients based on what you have on hand. For example, swap the sage with thyme or rosemary if you prefer, or use sweet potatoes instead of butternut squash for a twist.

Equipment Needed

• Baking sheet: For roasting the squash.
• Large mixing bowl: To toss the squash before roasting and to mix the sauce.
• Knife & cutting board: For peeling and chopping the squash.
• Medium saucepan: To prepare the creamy sauce.
• 9×13-inch casserole dish: For baking the casserole.
• Whisk: For mixing the sauce until smooth.

If you don’t have a dedicated casserole dish, a deep baking pan works just fine. And if you’re new to peeling butternut squash, a good vegetable peeler will make the job much easier!

Detailed Preparation Method

1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. In a large mixing bowl, toss the diced butternut squash with olive oil, chopped sage, salt, and pepper. Spread the squash evenly on the prepared baking sheet and roast for 25-30 minutes, or until tender and slightly caramelized.
3. While the squash is roasting, prepare the creamy sauce. In a medium saucepan, heat the heavy cream over medium heat. Stir in the nutmeg, a pinch of salt, and a few grinds of pepper. Cook for about 5 minutes, stirring frequently, until slightly thickened.
4. Remove the roasted squash from the oven and reduce the oven temperature to 375°F (190°C).
5. In your casserole dish, layer the roasted squash evenly. Pour the creamy sauce over the squash, ensuring every piece is coated.
6. In a small bowl, mix the breadcrumbs, Parmesan cheese, and melted butter until combined. Sprinkle the mixture evenly over the squash and sauce.
7. Bake the casserole for 20-25 minutes, or until the topping is golden brown and crispy.
8. Let the dish cool for a few minutes before serving. Enjoy the creamy, crunchy, and fragrant goodness!

Cooking Tips & Techniques

• Don’t crowd the squash: Spread the cubes out evenly on the baking sheet so they roast instead of steam.
• Fresh sage is key: While dried sage can work, fresh sage provides a much brighter flavor.
• Taste as you go: Adjust the seasoning in the sauce to suit your preference before pouring it over the squash.
• Breadcrumbs matter: Panko breadcrumbs create the crispiest topping, but regular crumbs work too.
• Watch the topping: Keep an eye on the casserole in the oven to ensure the breadcrumbs don’t burn—it’s better to under-toast than overdo it.

Variations & Adaptations

• Make it vegan: Use coconut cream instead of heavy cream, vegan butter, and dairy-free Parmesan for a plant-based version.
• Low-carb option: Replace breadcrumbs with crushed pork rinds or almond flour for a keto-friendly topping.
• Add some protein: Mix cooked sausage or shredded chicken into the casserole before baking.
• Seasonal twist: Swap butternut squash for sweet potatoes or even pumpkin for a different fall flavor.
• Switch the herbs: If sage isn’t your favorite, try thyme, rosemary, or even a combination of all three.

One personal favorite variation I’ve tried is adding dried cranberries to the topping for a pop of sweetness—it’s surprisingly good!

Serving & Storage Suggestions

This creamy butternut squash casserole with sage is best served warm, straight from the oven. Pair it with roasted turkey or chicken, and maybe a glass of white wine for a true fall feast. For presentation, sprinkle a little extra chopped sage on top—it adds color and makes the dish look extra inviting.

Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, pop it in a 350°F (175°C) oven for about 15 minutes or microwave individual portions. If freezing, skip the breadcrumb topping and add it freshly before baking.

The flavors of this casserole deepen overnight, so don’t be surprised if it tastes even better the next day!
