Parmesan-Butternut Squash Gratin Ingredients

For the Gratin

• Butternut Squash Main ingredient; provides sweetness and texture. Substitute with acorn squash for a similar flavor.
• Butter or Margarine Adds richness and moisture. For a dairy-free option, use olive oil or vegan butter.
• Garlic (finely chopped) For aromatic flavor. Can be substituted with garlic powder (1/8 teaspoon).
• Progresso™ Panko Bread Crumbs Adds crunch and texture. Swap with regular breadcrumbs for a different finish.
• Grated Parmesan Cheese Offers a salty, nutty flavor and creamy texture. Use a vegan cheese alternative for a dairy-free version.

• Pepper Adds a gentle heat. Use fresh ground black pepper for the best flavor.
• Chopped Fresh Parsley Provides a fresh, herbaceous finish. Can be replaced with other fresh herbs like thyme or sage.

How to Make Parmesan-Butternut Squash Gratin

1. Preheat your oven to 375°F (190°C). This initial step ensures the gratin bakes evenly and achieves that perfect golden crust.

2. Prepare the butternut squash by peeling, seeding, and cubing it. Cook the cubes in boiling water for about 10-15 minutes until tender. You want them soft enough to mash without hassle.

3. Mash the drained butternut squash in a bowl until it’s smooth and creamy, which will help create that luscious texture in your gratin.

4. Melt butter in a skillet over medium heat and sauté the finely chopped garlic until fragrant, about 1-2 minutes. This step infuses the dish with aromatic flavor.

5. Combine the sautéed garlic with the mashed squash. Gently stir in the panko breadcrumbs, grated Parmesan cheese, salt, and pepper until everything is mixed and cohesive.

6. Spread the squash mixture evenly in a greased baking dish, smoothing the top to ensure even cooking and browning.

7. Bake in your preheated oven for 30-35 minutes or until the top is golden brown and crispy, creating a beautiful contrast to the creamy base.

8. Garnish with freshly chopped parsley before serving to add a touch of color and freshness to your gratin.

Optional: Sprinkle extra Parmesan on top before baking for an even cheesier finish.

Make Ahead Options

Preparing the Parmesan-Butternut Squash Gratin in advance makes weeknight meals a breeze! You can prepare the butternut squash mixture (steps 2-6) up to 24 hours in advance. Simply mash the cooked butternut squash and combine it with sautéed garlic, breadcrumbs, and Parmesan, then store it in an airtight container in the refrigerator. To maintain maximum quality, press a piece of plastic wrap directly onto the surface before sealing; this helps prevent browning. When you’re ready to serve, spread the mixture in a greased baking dish, bake at 375°F (190°C) for 30-35 minutes, and watch as your comforting gratin transforms into an irresistible centerpiece for dinner.
