This comforting savoury butternut squash bake (or casserole) combines cubbed butternut squash, chopped bacon, and sliced mushrooms with a buttery crumble topping. It’s a terrific make-ahead side dish, perfect for gracing your holiday table, or Sunday supper!
Butternut squash is one of those vegetables that even your vegetable haters will love. A savory butternut squash casserole with bacon is a savory casserole topped with an amazing buttery crumble that will compliment any meal.
It’s a fabulous Thanksgiving or Christmas side because it goes so well with turkey, beef or ham and will compliment a baked green bean casserole.
When you need several side dishes for the holidays, a butternut squash bake goes great with a sweeter side like baked sweet potato casserole.
To bring out the flavor, the butternut squash is first browned in a skillet with bacon and onions and then baked until it’s just softened. Add a savory crumble with walnuts to the top and bake a little more until golden brown.
The butternut squash has a wonderful smokey applewood bacon flavor, but it’s the crumble that makes the dish. Think of a fruit crumble, but savory instead of sweet.
To speed things up, you can find butternut squash already cut and cubed for you in the produce section. Most groceries in my area carry this. If not bite the bullet, it’s not that hard to peel and cut one.
How do you peel a butternut squash
The outer layer of a butternut squash is a nightmare to peel. Try cutting off both ends first, pricking it with a fork and microwave it for about 3 minutes. This will soften the skin and make it much easier to peel.
