  • 1 large butternut squash peeled, deseeded and sliced or cut up into the size you prefer
  • 1/4 teaspoon salt
  • 1 teaspoon olive oil
  • 1/4 cup basil pesto (ready made or this protein-packed hemp seed basil pesto)
  • 1/2 cup cream or half and half
  • pinch of salt
  • pinch of black pepper
  • 1 cup panko breadcrumbs
  • 1 cup freshly grated Parmesan cheese
  • 1/2 cup sliced almonds


  1. Preheat the oven to 425 degrees F. Spread the butternuts squash pieces in a single layer and season with salt and olive oil. Toss them well in the seasoning and roast the squash for 12 minutes until tender.
  2. Use a large 3-quart oven-safe dish or 6 ramekins (8-ounce capacity) or 10 ramekins (6-ounce capacity) and layer the squash slices or cubes at the bottom of the dish.
  3. In a bowl mix the basil mixture ingredients and drizzle that over the squash evenly (it will not cover the squash entirely).
  4. Sprinkle the Panko mixture over the squash and then bake the gratin for 8-20 minutes (depending on the size dish you chose) until the tops are golden and crunchy.

Recipe Notes

  • These butternut squash gratins cook much faster when the squash is already roasted. That being said, you can very much make them with raw fresh squash and have it all cook together.
  • As a variation, you can use the topping I use in this Crunchy Sweet Potato Gratin recipe.
  • I’m making this gratin for a crowd I would opt for a large 3-quart baking dish instead of individual ramekins.
