Step‑by‑Step Instructions for Butternut Squash Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is perfect for roasting the butternut squash and apples, allowing their natural sweetness to develop. While the oven warms up, gather your ingredients and prepare your baking dish by lightly greasing it with olive oil to prevent sticking.
Step 2: Prepare the Vegetables and Fruits
Cube the fresh butternut squash and firm apples into bite-sized pieces. In a large mixing bowl, toss them with olive oil and a drizzle of maple syrup, ensuring they’re evenly coated. Spread the mixture on a baking sheet in a single layer and roast in the oven for about 20-25 minutes, or until they become tender and golden.
Step 3: Caramelize the Fennel and Onion
While the squash and apples roast, thinly slice the fennel and onion. Heat a skillet over medium heat and add a splash of olive oil. Sauté the fennel and onion for approximately 10 to 15 minutes, stirring occasionally until they turn golden and fragrant, creating a sweet, caramelized base for your butternut squash casserole.
Step 4: Cook the Sausage
In the same skillet, add the sweet Italian sausage, breaking it into crumbles as it cooks. Sauté for about 5-7 minutes, or until the sausage is browned and cooked through. This step adds a savory depth to your casserole, balancing the sweetness of the squash and apples beautifully.
Step 5: Combine the Ingredients
Once the squash and apples are perfectly roasted, remove them from the oven. In a large mixing bowl, combine the roasted mixture with the caramelized fennel, onion, and cooked sausage. Stir gently until all ingredients are well incorporated, creating a harmonious blend of flavors for your butternut squash casserole.
Step 6: Assemble and Bake
Transfer the combined mixture into your prepared baking dish. Sprinkle the top generously with grated Gruyere cheese, creating a deliciously creamy layer. Return the casserole to the oven and bake for an additional 20-25 minutes, or until the cheese is bubbly and golden brown, signaling a finished, comforting butternut squash casserole.
Step 7: Serve Warm
Once baked, let the butternut squash casserole cool for a few minutes before serving. This dish shines as a hearty main course or delightful side. The warm, enticing aroma will draw everyone to the table, ready to enjoy a lovely slice of autumn comfort.
How to Store and Freeze Butternut Squash Casserole
Fridge: Store your butternut squash casserole in an airtight container for up to 3 days. This allows flavors to meld beautifully while keeping it fresh.
Make-Ahead: You can assemble the casserole a few days in advance. Just cover it tightly and refrigerate. Add the cheese right before baking to ensure it melts perfectly.
Freezer: Although not recommended, if necessary, you can freeze the casserole for up to 2 months. Freezing may affect its texture, so be prepared for a slight change upon reheating.

Butternut Squash Casserole Recipe FAQs
What type of butternut squash should I use?
Absolutely! Fresh butternut squash is preferred for the best texture and natural sweetness. Look for one that feels heavy for its size, with a smooth, unblemished skin. Avoid any squash with dark spots or soft areas, as this indicates overripeness.
How long can I store the casserole in the fridge?
You can store your butternut squash casserole in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy, simply reheat in the oven at 350°F (175°C) until heated through. The flavors will only get better as they meld together!
Can I freeze leftover casserole?
Although it’s not recommended due to potential texture changes, you can freeze your casserole for up to 2 months. To do this, let it cool completely before wrapping tightly in plastic wrap and then in aluminum foil. When ready to eat, thaw it overnight in the fridge and bake uncovered at 350°F (175°C) for about 20-25 minutes until hot and bubbly.
What if I have dietary restrictions or allergies?
Very good question! This butternut squash casserole is quite versatile. For a gluten-free option, ensure that all your ingredients, such as sausage and cheeses, are certified gluten-free. If you’re vegetarian, simply omit the sausage or replace it with a meat substitute. Always double-check labels for any allergens, especially with prepared ingredients like sausage.
Why did my casserole turn out watery?
If your casserole is watery, it might be due to pre-cooking moisture from the vegetables or apples. To prevent this, make sure to roast the butternut squash and apples until they are tender but not mushy, allowing excess moisture to evaporate. If you add extra ingredients like zucchini or mushrooms, keep in mind they have high moisture content and can contribute to a watery casserole.
What are good variations for this casserole?
The more the merrier! You can easily customize this butternut squash casserole with different ingredients or toppings. Consider swapping sweet sausage for turkey sausage or omitting meat for a vegetarian delight. Adding spices like nutmeg or cinnamon can enhance the sweetness, while extra veggies like spinach or kale can boost nutritional value and color.
