Ingredients

  • 2 medium butternut or acorn squash
  • 2 Tbsp. rosemary
  • salt
  • pepper

Instructions

  1. Cook the squash in a 350°F oven until tender.
  2. Allow the squash to cool, then peel and mash.
  3. Add rosemary, salt, and pepper to taste.
  4. Spread the mashed squash into a buttered 13 x 9-inch pan.
  5. Shred Asiago cheese and completely cover the top of the squash.
  6. Bake in the 350°F oven for 25 to 30 minutes until bubbly.

Tips & Substitutions

For a creamier texture, consider adding a splash of cream or milk to the mashed squash. If you don’t have Asiago cheese, Gruyère or even a sharp cheddar can work well as substitutes. Fresh rosemary is best, but dried can be used in a pinch—just reduce the quantity. Ensure the squash is thoroughly cooked for optimal flavor.

Serving Suggestions

This Squash Au Gratin pairs beautifully with roasted meats or a simple green salad for a complete meal. You can serve it alongside dishes like Ozark Pumpkin Bread for a seasonal touch. For a vegetarian meal, consider adding a side of Sour Cream Limas for balanced protein.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place in a baking dish and cover with foil, heating in a 350°F oven until warmed through, about 15-20 minutes. You can also microwave individual portions, but baking helps maintain the texture.
