Ingredients

Scale
  • 1 medium butternut squash, peeled and cubed (about 3 cups)
  • 3 tbsp butter, divided
  • 1 small onion, finely chopped
  • 1 clove garlic, minced
  • 2 eggs, lightly beaten
  • 1/2 tsp each cinnamon and nutmeg
  • Salt and pepper

Pistachio Crumb Topping

  • 1 cup cubed stale bread (preferably ciabatta)
  • 1 tbsp olive oil
  • 1 clove garlic, minced
  • 1 tsp lemon zest
  • 2 tbsp each chopped fresh mint and parsley
  • ½ cup coarsely chopped pistachios

Instructions

  1. preheat the oven to 350F, and lightly butter a 1-quart baking dish.
  2. In a large saucepan set over medium-high heat, combine the squash cubes and just enough water to cover. Cook for 20-25 minutes, or until very tender.
  3. Meanwhile, in a skillet set over medium-high heat, melt the remaining tablespoon butter. Add onion and garlic, and saute for 5 minutes or until soft and golden. Add spices and continue cooking, stirring frequently, for 1 minute to wake up the spices.
  4. Drain the cooked squash, and return to the pot. Add 2 tbsp butter, and mash until smooth and creamy. Season with salt and pepper to taste.
  5. Add the cooked onion mixture and eggs to the mashed squash, and stir until well combined. Using a spatula, smooth the mixture into the prepared baking dish.
  6. To prepare the topping, pulse the bread cubes in a food processor until you have large, coarse crumbs. Set aside.
  7. In a large frying pan, heat oil and garlic until garlic is fragrant, about 1 minute. Add bread crumbs all in one go. Cook, stirring frequently, for 4 to 5 minutes or until crumbs are golden and crisp. Remove from heat and stir in remaining ingredients. Season to taste with salt and pepper.
  8. Sprinkle the crumb mixture over the casserole, and bake in preheated oven for 30-40 minutes or until hot and lightly browned.
