Instructions

Step 1: Preparing the Vegetables

Begin by thoroughly washing all the vegetables. Use a vegetable brush if necessary to remove dirt and debris. Peel the acorn squash, butternut squash, and parsnips carefully using a sharp peeler. For uniformity and ease of layering, slice each vegetable into thin, even slices—approximately ⅛ inch thick—using a sharp chef’s knife or a mandoline slicer. If using a mandoline, ensure safety gloves are worn to prevent accidental cuts. Arrange the slices in separate bowls or on a tray for easy assembly later.

Step 2: Making the Creamy Sauce

In a medium saucepan, combine the heavy cream and milk. Warm over low to medium heat, stirring frequently with a whisk to prevent scorching. When the mixture begins to steam, add the grated cheese gradually, stirring continuously until melted and smooth. Incorporate the nutmeg, salt, and pepper, tasting and adjusting seasoning as needed. The sauce should be creamy and velvety, with a slight thickness that will coat the vegetables evenly without being runny. Remove from heat once done and set aside.

Step 3: Assembling the Gratin

Preheat your oven to 350°F (175°C). Grease your baking dish generously with unsalted butter to prevent sticking and add flavor. Begin layering the vegetables in the dish, starting with a layer of acorn squash slices, followed by butternut squash, and then parsnips. Continue layering until all slices are used, pressing down gently to pack the layers neatly. Pour the warm cheese sauce evenly over the layered vegetables, ensuring each layer is well coated. Use a spatula to spread the sauce if necessary, reaching the edges for full coverage. This ensures even baking and a luscious top crust.

Step 4: Baking and Browning

Cover the assembled gratin with aluminum foil, tenting it slightly to prevent sticking to the sauce. Bake in the preheated oven for approximately 45 minutes. This initial baking allows the vegetables to become tender and the flavors to meld. After 45 minutes, carefully remove the foil and increase the oven temperature to 375°F (190°C). Bake uncovered for an additional 15-20 minutes, or until the top is beautifully golden brown and bubbling. The cheese on top should be crisp and slightly caramelized, adding texture and visual appeal.

Step 5: Resting and Serving

Once baked, remove from the oven and let the gratin rest for about 10 minutes. Resting helps the dish set, making it easier to serve clean slices. Garnish with freshly chopped herbs like parsley or thyme for added freshness and color. Serve warm as a side dish alongside roasted meats, a fresh green salad, or crusty bread to complete your meal.

Preparation Tips

• Uniform Slicing: Use a mandoline slicer if available for perfectly even slices. This ensures consistent cooking and an attractive presentation.
• Vegetable Prep: Peel and slice vegetables just before assembly to prevent oxidation and discoloration, especially with parsnips which can brown quickly.
• Cheese Selection: Gruyère provides a nutty flavor that complements the sweetness of the vegetables. For a sharper taste, Parmesan can be mixed in. For vegan options, use nutritional yeast or plant-based cheeses.
• Layering Technique: Lay the vegetables flat and evenly in the dish to facilitate uniform cooking and an appealing layered look.
• Sauce Consistency: Adjust the thickness of the sauce by adding a splash more milk or cream if it seems too thick, or simmer longer if too thin.

Nutritional Information

Tips and Tricks

• Vegetable Variations: Incorporate other root vegetables like sweet potatoes or carrots for added color and nutrients.
• Cheese Alternatives: Use plant-based cheeses or nutritional yeast to make this dish vegan-friendly without sacrificing flavor.
• Flavor Enhancers: Add a pinch of smoked paprika or garlic powder to the cheese sauce for extra depth.
• Make-Ahead: Assemble the gratin one day in advance, cover tightly, and bake when needed. It enhances flavors and saves time.
• Texture Play: For a crunchier top, sprinkle breadcrumbs or crushed nuts before the final bake.

Add-ons

• Cooked bacon bits or pancetta for non-vegetarian options
• Caramelized onions layered within for extra sweetness
• Chopped fresh herbs like thyme, rosemary, or sage mixed into the sauce or sprinkled on top
• Spicy red pepper flakes for a hint of heat

Side Dishes

• Roasted chicken or turkey
• Grilled salmon or white fish
• Fresh mixed greens with vinaigrette
• Crusty Italian bread or baguette slices
• Steamed green beans or asparagus

Improvements and Variations

• Vegan Version: Substitute dairy ingredients with cashew cream, non-dairy milk, and vegan cheese. Use nutritional yeast for cheesy flavor.
• Low-Fat Option: Use skim milk and reduced-fat cheese or plant-based alternatives.
• Spice It Up: Add cayenne pepper or hot sauce to the sauce for a spicy kick.
• Herb Infusion: Incorporate fresh herbs like sage, thyme, or rosemary into the layers or sauce for aromatic complexity.

Save and Store

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake at 350°F (175°C) until heated through, or microwave in short bursts. For best results, reheat in the oven to preserve the crispy top layer. To freeze, assemble the gratin, wrap tightly with plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
