Butternut squash is my favorite fall vegetable. Yep, even more so than pumpkin! It’s just easier to find and work with, in my opinion.
I use it often in fall side dishes like in this Roasted Butternut Squash Risotto with Brussels Sprouts and in Roasted Butternut Squash and Brussels Sprouts Medley.
I don’t only use it in recipes with Brussels sprouts though. It’s also great with apples like in Butternut Squash Apple Flatbread and as the star of the show in Warm & Spicy Butternut Squash Soup.
In this recipe for Butternut Squash Gratin, butternut squash is, once again, the star of the show!

How to Make Butternut Squash Gratin
Prep!
Chop the shallot, mince the garlic, and strip the leaves off of the stems of thyme.
Preheat your oven to 400°F.
Create!
Peel and slice the long neck part of the butternut squash into 1/4″ thick rounds and layer into the bottom of a medium size casserole dish. You can save the bottom bulb portion for another use.
Melt 2 tablespoon of the butter over medium heat in a medium size skillet and add the shallot, garlic, and thyme. Cook for 2-3 minutes, or until the shallot is softened.
Stir in the heavy whipping cream, salt and pepper and cook for 1-2 minutes until hot and bubbly.
Pour the hot cream mixture evenly over the butternut squash.
Sprinkle on the Parmesan cheese.
Melt the remaining 1 tablespoon of butter and stir in the almond flour with a fork until it resembles crumbs. Spread the almond flour crumbs over the butternut squash.
Tip: if you’d like to lower the carb count even more, I have seen people use pork rinds as breadcrumbs. I refuse to use them, but more power to ya if you enjoy them!
Cover and bake for 45 minutes, or until the squash is fork-tender and the crumb topping is lightly browned. Remove the cover and bake an additional 5-10 minutes to brown the crumbs more, if desired.
Present!
Top with extra fresh thyme, if desired, and serve hot.
