How to Make Butternut Squash & Sage Gratin
Prepare Your Ingredients: Start by peeling and slicing your butternut squash into thin rounds to ensure even cooking. You want them about 1/4 inch thick—this allows for tender layers in every bite.
Sauté Garlic and Sage: In a skillet over medium heat, melt a tablespoon of butter and sauté minced garlic with chopped sage until fragrant—about 2 minutes. This step fills your kitchen with irresistible aromas!
Create Your Cream Mixture: In a bowl, whisk together heavy cream, grated Parmesan cheese, salt, pepper, and just a hint of nutmeg. The mixture should be smooth and inviting with rich flavors ready to embrace our squash.
Layer It Up: Grease a baking dish with butter and start layering your sliced butternut squash. Pour half of the cream mixture over the first layer before adding another layer of squash followed by remaining cream. Don’t worry about perfection; rustic looks are charming!
Bake Until Bubbly: Cover your dish with aluminum foil and bake at 375°F (190°C) for 30 minutes. Remove the foil then bake for another 20-30 minutes until golden brown on top—the anticipation will drive you wild!
Let It Rest: Once baked to perfection, allow your gratin to rest for about 10 minutes before serving. This helps all those delicious layers settle down so they don’t escape when you scoop them out.
Now you’re ready to serve this show-stopping Butternut Squash & Sage Gratin! Whether it’s alongside turkey at Thanksgiving or as a comforting side dish any day of the week, each bite will feel like pure joy wrapped in creamy goodness!
