How to Prepare Sage Butternut Squash Gratin

Preparing Sage Butternut Squash Gratin is a straightforward process that results in a delectable dish. Below are detailed steps to guide you through each phase, including practical tips.

Step 1: Prepare the Butternut Squash

To start, select a ripe butternut squash, which should feel heavy for its size and have a smooth, firm skin.

Peeled and sliced: Use a vegetable peeler to remove the tough outer skin. Once peeled, slice the squash into thin half rounds (approximately 1/8 inch thick). For safety, it may be easier to cut the squash in half lengthwise and scoop out the seeds with a spoon first. Then slice each half into semi-circular pieces.

Tip: A sharp knife and a stable cutting board are crucial for safety. If you’re having difficulty cutting, microwaving the squash for about 30 seconds can soften it slightly and make slicing easier.

Step 2: Create the Sauce

Melt the butter: Heat 3 tablespoons of butter in a small saucepan over medium heat.
Sauté shallots and garlic: Once melted, add one large minced shallot and four roughly chopped garlic cloves. Cook these for 1 to 2 minutes until they become fragrant and translucent.

Tip: Be careful not to brown the shallots and garlic too much; you want them soft for a sweet flavor rather than bitter.
Make a roux: Stir in 1 tablespoon of all-purpose flour, mixing it well with the butter, shallots, and garlic to form a smooth roux. Cook this for about a minute to remove the raw flour taste, stirring constantly.
Add liquids: Gradually whisk in 1 cup of low-sodium vegetable stock, then stir in 1 cup of heavy whipping cream. Keep stirring gently until the mixture thickens slightly—be cautious not to let it boil.
Season the sauce: Add in 15 fresh sage leaves, 1/2 teaspoon of pepper, and 1/2 teaspoon of onion powder (if using) to the mixture. The goal here is to infuse the flavors of the sage throughout the sauce.

Step 3: Assemble the Gratin

Prepare the baking dish: Butter a 9×13 inch baking dish to prevent sticking.
Layer the gratin: Pour a third of the sauce into the bottom of the baking dish, then sprinkle lightly with grated Parmesan cheese. Layer the squash slices in overlapping rows on top. Repeat this process, pouring the remaining sauce over the top and finishing with more Parmesan.

Step 4: Bake

Cover and bake: Cover the dish tightly with parchment paper followed by aluminum foil to keep the moisture in. Place it in a preheated oven at 375°F (190°C) and bake for 20 minutes.
Finish baking uncovered: After 20 minutes, remove the cover, sprinkle the remaining Parmesan cheese on top, and bake uncovered at 400°F (200°C) for an additional 10 minutes until the top is golden and bubbling.
Let it rest: Once out of the oven, let the gratin rest for 5 minutes before serving. This resting time allows the flavors to meld together better.
Garnish and serve: Optionally garnish with chopped fresh chives for a pop of color and flavor.

How to Store Sage Butternut Squash Gratin

Proper storage of the gratin can help reduce food waste and keep it fresh for longer. Here’s how to store it:

In the Refrigerator: After it cools, transfer leftovers to an airtight container. It can be stored in the refrigerator for up to 4 days.
Reheating: To reheat, place it back in the oven at 350°F (175°C) until warmed through. Adding a splash of cream or broth while reheating can help recover moisture.
Freezing: You can also freeze portions of the gratin. Keep it in a freezer-safe container for up to 3 months. When ready to use, thaw in the refrigerator overnight and then reheat in the oven.

Tip: Consider labeling your storage containers with the date and content to keep track of freshness!

Tips for Mastering Sage Butternut Squash Gratin

Here are some recommendations for creating the best Sage Butternut Squash Gratin:

Uniform Slices: Ensure butternut squash slices are uniform in thickness to promote even cooking.
Thickening the Sauce: If your sauce isn’t thick enough after cooking, you can mix in a small amount of cornstarch dissolved in water until it thickens to your liking.
Taste as You Go: Adjust seasoning throughout preparation to ensure the flavors complement each other perfectly!
Don’t Rush the Baking: Covering for part of the bake ensures the squash cooks through before getting that nice golden color on top.

Common Mistake: Avoid overcooking; keep an eye on the top layer to prevent it from burning.

Variations

While this traditional recipe is delightful as is, you can make several adjustments based on preference or dietary needs:

Cheese Alternatives: Swap Parmesan with Gruyère or cheddar for a different flavor profile.
Vegetable Additions: Incorporate thinly sliced leeks, mushrooms, or spinach for added color and nutrients.
Herb Swaps: If you’re not a fan of sage, try thyme or rosemary, which also pair well with butternut squash.
Nutty Finish: Add a topping of toasted, crushed walnuts or pecans for additional texture and flavor.
