Creamy Butternut Squash Gratin with Sage

  • Author: David
  • Total Time: 1 hour 5 minutes
  • Yield: 6 servings 1x

Description

A rich, buttery, and earthy fall side dish featuring tender layers of butternut squash baked in a creamy sage-infused sauce with a golden cheese topping. Perfect for holidays or cozy dinners.

Ingredients

Scale
  • 2 lbs butternut squash, peeled, seeded, and thinly sliced (about 1/8 inch thick)
  • 2 tbsp unsalted butter (plus extra for greasing)
  • 1 cup heavy cream
  • 1/2 cup whole milk
  • 1 garlic clove, minced
  • 1 tbsp fresh sage, finely chopped (or 1 tsp dried sage)
  • 1/2 tsp salt
  • 1/4 tsp ground black pepper
  • 1/4 tsp ground nutmeg
  • 3/4 cup grated Gruyère cheese (or Swiss or sharp cheddar)
  • 1/4 cup grated Parmesan cheese
  • Extra fresh sage leaves (optional, for garnish)
  • Coarse sea salt (optional, for garnish)

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
  2. Slice the butternut squash thinly, about 1/8 inch thick.
  3. In a medium saucepan, melt butter over medium heat. Add minced garlic and cook for 30 seconds until fragrant.
  4. Pour in heavy cream and milk, then stir in sage, salt, pepper, and nutmeg. Warm for 3–5 minutes until slightly thickened; do not boil.
  5. Arrange half of the squash slices in the prepared dish, overlapping slightly. Pour half of the cream mixture over and sprinkle with half of the Gruyère cheese.
  6. Repeat with remaining squash, cream mixture, and top with remaining Gruyère and all of the Parmesan cheese.
  7. Cover with foil and bake for 25 minutes.
  8. Remove foil and bake uncovered for another 20–25 minutes until golden brown and bubbling.
  9. Let rest for 10 minutes before serving. Garnish with crispy sage leaves or a sprinkle of sea salt.

Notes

For best results, slice squash evenly for uniform cooking. Warm the cream mixture to infuse flavors and prevent curdling. If gratin isn’t browning evenly, broil for 2–3 minutes. Can be made ahead and refrigerated up to 24 hours before baking; add 5–10 minutes to bake time. Leftovers store well for up to 4 days and taste even better the next day.
