Step-by-step Preparation of Butternut Squash Casserole
Making a butternut squash casserole is not only a great way to enjoy autumn flavors, but it also showcases how simple ingredients can come together to create something memorable. Follow these easy steps, and you'll have a delicious dish ready to impress your friends and family!
Preheat and Prepare Your Baking Dish
Start by preheating your oven to 400°F. While that's warming up, grab a 13-by-9-inch baking dish and toss together 2 ½ lb. of peeled and chopped butternut squash, 3 medium parsnips, 3 tablespoons of olive oil, 1 tablespoon of chopped fresh sage, and some salt and pepper to taste. I like to use 2 teaspoons of salt and 1 teaspoon of pepper, along with 1 ½ teaspoons of fresh thyme. Give it a good mix to ensure everything is evenly coated—a perfect foundation for your casserole!
Roast the Butternut Squash and Parsnips
Once your oven is heated, place your baking dish into the oven. You'll want to roast the vegetables until they get that lovely tender texture, which usually takes about 60 to 80 minutes. Stir them every 20 minutes to ensure even roasting. Your kitchen is going to smell absolutely divine!
Cook Turkey Bacon to Crispy Perfection
While those veggies are roasting, it's time to cook 6 slices of turkey bacon. Heat a large skillet over medium heat, and cook the bacon, turning occasionally until it's crispy—this usually takes around 10 to 12 minutes. Once done, transfer the crispy goodness to a paper towel-lined plate to drain. Allow it to cool and then crumble it into large pieces. This crunchy addition will add an irresistible flavor!
Sauté the Onions and Kale Combination
In the same skillet, without draining the drippings, add 2 thinly sliced onions and cook over medium heat. You want them to get soft and golden, which typically takes about 25 to 35 minutes. When they’re done, toss in a medium bunch of chopped kale, 2 tablespoons of salted butter, and 1 tablespoon of apple cider vinegar, along with the remaining ½ teaspoon of salt and ½ teaspoon of pepper. Cover and let it cook for 1 to 2 minutes, stirring once to wilt that kale perfectly.
Assemble the Casserole Layers
Carefully add the combination of kale and onions to the roasted squash and parsnips in the baking dish. Gently mix everything together and spread it into an even layer. Now, sprinkle 1 cup of shredded gruyère cheese on top. Cheese lovers, rejoice—this will add a delicious creaminess!
Add the Finishing Touches and Bake
Now for the final touch! Place your casserole back in the oven and bake until the cheese melts, about another 5 minutes. Finish off with a scattering of ¼ cup of smoked or plain roasted almonds, and don’t forget to garnish with sage and thyme leaves for that extra pop!
And there you have it! Your butternut squash casserole is ready to be devoured—perfect for a cozy dinner or a potluck. Enjoy!

Variations on Butternut Squash Casserole
When it comes to butternut squash casserole, the fun doesn't stop with just one version! Here are two delicious variations that can add a twist to this comforting dish.
Vegetarian Butternut Squash Casserole
For a plant-based delight, skip the turkey bacon and load up on veggies! Sweet potatoes, mushrooms, and a mix of seasonal greens like spinach or Swiss chard make for a colorful and hearty casserole. You can also drizzle a bit of balsamic reduction for an extra layer of flavor.
Spicy Butternut Squash Casserole with Chipotle
Ready to turn up the heat? Add chipotle peppers in adobo sauce to your butternut squash casserole for a smoky kick. Combine it with black beans and a sprinkle of Mexican cheese to create a fiesta on your plate. This flavorful addition not only enhances the taste but also gives a vibrant color that’s hard to resist!
These variations are easy to prepare and can make your casserole the star of any meal. Which one will you try first?
Cooking Tips for Butternut Squash Casserole
Perfecting the Roasting Process
To achieve perfectly roasted butternut squash, aim for even, golden-brown edges. Cut your squash and parsnips into uniformly sized pieces to ensure even cooking. Toss them in olive oil and season well with salt and pepper. Don't skip the stirring every 20 minutes; it promotes an even roast and prevents any sticking. You can also try adding a dash of cinnamon or nutmeg for an extra flavor kick!
Storage Tips for Leftovers
Have leftovers? Store your butternut squash casserole in an airtight container in the fridge for up to four days. For those busy weeknights, you can reheat individual portions in the microwave or oven. Want to freeze it? Just portion it out, and it’ll keep well for up to three months.
