The method

Step by step

  1. 1

    Preheat your oven to 190°C (375°F) and lightly grease a 2-quart (approximately 2-liter) baking dish.

    About 5 min

  2. 2

    Place the sliced yellow squash in a steamer basket over boiling water, cover, and steam for 10-15 minutes until very tender.

    About 15 min

    Cook’s note: If you don't have a steamer, you can boil the squash in a small amount of water until tender, then drain very well.

  3. 3

    While the squash steams, melt the sautéing butter in a small skillet over medium heat.

    About 1 min

  4. 4

    Add the finely chopped onion and cook for 5-7 minutes until soft and translucent, then set aside.

    About 7 min

  5. 5

    Once tender, drain the steamed squash thoroughly and transfer it to a large bowl.

    About 2 min

    Cook’s note: Press the squash gently to remove as much excess water as possible for a better casserole texture.

  6. 6

    Mash the squash with a potato masher or fork until it's broken down but still has some texture.

    About 2 min

  7. 7

    Add the sautéed onion, beaten eggs, the filling butter, the filling breadcrumbs, sugar, salt, and black pepper to the mashed squash.

    About 2 min

  8. 8

    Stir everything together until well combined, then pour the mixture into the prepared baking dish and spread evenly.

    About 1 min

  9. 9

    In a small bowl, melt the topping butter in the microwave or on the stovetop.

    About 1 min

  10. 10

    Add the topping breadcrumbs to the melted butter and toss until the crumbs are evenly coated.

    About 1 min

  11. 11

    Sprinkle the buttered breadcrumbs evenly over the squash mixture in the baking dish.

    About 1 min

  12. 12

    Bake for 45-50 minutes, until the topping is golden brown and the casserole is set in the center.

    About 45 min

  13. 13

    Remove from the oven and let it rest for at least 5 minutes before serving.

    About 5 min

    Cook’s note: Resting helps the casserole firm up, making it easier to slice and serve.
