  • 1 medium butternut squash
  • 2 tbsp olive oil
  • 2 tbsp butter
  • 1/2 cup shallot, chopped (1 medium shallot)
  • 1/4 cup garlic, chopped (5 cloves)
  • 1/3 cup panko breadcrumbs (or GF breadcrumbs)
  • 1/2 cup grated parmesan cheese
  • 3 tbsp chopped fresh rosemary (plus more for garnish)
  • 1/4 tsp sea salt
  • 1/4 tsp freshly ground black pepper
  1. Preheat oven to 350°, prepare a baking dish by coating lightly with olive oil. (I used a 8.5x8.5" square baking dish)

  2. Peel the butternut squash, and slice in half lengthwise. Scoop out seeds, and cut into 1/2" thick slices. Arrange squash in the baking dish in an overlapping fashion

  3. In a medium skillet over medium-high heat saute shallot and garlic for 4 minutes

  4. Combine breadcrumbs, parmesan, and rosemary in a small bowl. Spoon 3 tbsp of shallot butter mixture into breadcrumb mixture and stir until well combined

  5. Pour shallot garlic butter over butternut squash, lifting squash slices to coat all squash with mixture. Season squash with salt and pepper

  6. Coat butternut squash with breadcrumb mixture

  7. Bake uncovered for 55 minutes or until squash is tender and breadcrumbs are browned and crisp

  8. Serve immediately with a sprinkle of additional fresh rosemary on top
