Butternut Squash Casserole Ingredients
For the Casserole
• Peeled and Chopped Butternut Squash – The creamy base that becomes the heart of the dish; pre-peeled options make meal prep easier.

• Olive Oil – Helps with roasting while adding healthy fat; feel free to use avocado oil as a great substitute.
• Chopped Fresh Sage Leaves – Adds an earthy flavor that complements the squash; dried sage works too—just use less.
• Kosher Salt – Brings out the flavors of all ingredients; table salt can replace it but use less.
• Black Pepper – For essential seasoning; any pepper type works if you prefer a different heat.
• Chopped Fresh Thyme – Offers aromatic notes; dry thyme is a good alternative, but reduce the quantity.
• Slices Bacon – Infuses a smoky richness; turkey bacon is a lighter substitute for this savory treat.
• Onions (thinly sliced) – Provides natural sweetness and acts as the flavor base; shallots can be swapped for a similar taste.
• Medium Bunch Kale (stemmed and chopped) – Adds healthy greens and texture; spinach can be an excellent alternative.
• Salted Butter – Enhances richness; unsalted or plant-based butter can also work beautifully.
• Apple Cider Vinegar – Helps to balance flavors and brightens the dish; lemon juice is a great substitute.
• Shredded Gruyère (or Swiss) Cheese – Offers melty and savory richness that pulls everything together; Montgomery Jack or mozzarella are good substitutes.

Step‑by‑Step Instructions for Butternut Squash Casserole
Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 400°F (200°C). While the oven heats up, grease a large baking dish with a bit of olive oil or butter to prevent sticking. This savory butternut squash casserole requires an ample space for baking, so choose a dish that can comfortably hold all your ingredients.
Step 2: Mix the Vegetables
In a large mixing bowl, combine the peeled and chopped butternut squash and parsnips with the olive oil, chopped fresh sage, kosher salt, and black pepper. Toss this mixture thoroughly until the vegetables are evenly coated, allowing the flavors to blend. This step will add dimension to your savory butternut squash casserole.
Step 3: Cook the Bacon
Place a large skillet over medium heat, and add the slices of bacon. Cook for about 6-8 minutes or until the bacon is crisp and golden. Once cooked, remove the bacon from the skillet and let it drain on a paper towel. Keep the drippings in the skillet for the next step, as they will add wonderful flavor to your casserole.
Step 4: Caramelize the Onions
In the same skillet with the bacon drippings, add the thinly sliced onions. Cook on medium-low heat for about 10-12 minutes, stirring occasionally, until the onions turn golden brown and caramelized. This step will enhance the sweetness of your savory butternut squash casserole and elevate its overall taste.
Step 5: Sauté the Kale
To the caramelized onions, add the chopped kale. Sauté for an additional 3-4 minutes until the kale wilts and becomes tender. Stir in the mixture of butternut squash and parsnips next. This combination of vegetables will create a hearty, flavorful base for your casserole.
Step 6: Combine with Bacon and Cheese
Once mixed, fold in the crispy bacon and half of the shredded Gruyère cheese. Sprinkle apple cider vinegar over the mixture, then stir gently to create a cohesive filling. This blend of ingredients transforms your savory butternut squash casserole into a delightful medley of flavors ready for baking.
Step 7: Add Toppings and Bake
Transfer the vegetable mixture into the prepared baking dish, spreading it out evenly. Top with the remaining Gruyère cheese and chopped smoked almonds for an irresistible crunch. Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the edges are bubbly, signaling that the casserole is ready to delight your guests.
Step 8: Rest Before Serving
Remove the butternut squash casserole from the oven and allow it to rest for about 5-10 minutes before serving. This resting period lets the flavors meld beautifully as the casserole cools slightly, making it easier to dish out. Serve warm and enjoy the deliciousness of this savory twist on a classic recipe!

Savory Butternut Squash Casserole Recipe FAQs
How do I choose a ripe butternut squash?
Absolutely! When selecting a butternut squash, look for one that feels heavy for its size and has a uniform beige color. The skin should be smooth without dark spots or soft areas. Opt for squash that is firm to the touch, which indicates freshness.
How long can I store leftover butternut squash casserole?
Very! You can store leftover casserole in an airtight container in the refrigerator for up to 3 days. Make sure to let the casserole cool completely before refrigerating. This ensures the best flavors and textures when you reheat it.
Can I freeze butternut squash casserole?
Absolutely! Freezing is a great way to save time. To freeze, prepare the casserole up to the baking step, then wrap it tightly in plastic wrap followed by aluminum foil. This can keep it fresh in the freezer for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge and bake it at 350°F (175°C) for about 25-30 minutes or until heated through.
What should I do if my casserole is too watery?
If you find your casserole is too watery, don’t worry! This can happen if the vegetables release too much moisture during cooking. To fix this, you could try mixing in a tablespoon of cornstarch to absorb some of the liquid before baking. Alternatively, you can also bake it a bit longer to allow excess moisture to evaporate. Keep an eye on it to ensure it doesn’t dry out while doing so!
Is this butternut squash casserole suitable for vegetarians?
Yes indeed! This savory butternut squash casserole is vegetarian-friendly as it is. However, if you want to add a meaty twist, you can incorporate crumbled Italian sausage or turkey bacon. For a vegan adaptation, consider using plant-based bacon and replacing butter with a vegan alternative, ensuring all ingredients align with your dietary needs.
