Ingredients

  • 3 cups mashed cooked butternut squash
  • 1/4 cup butter
  • 1 tablespoon brown sugar
  • 1/4 teaspoon salt
  • dash of white pepper
  • 1 1/2 tablespoons butter
  • 6 cups sliced unpared Jonathan apples
  • 1/4 cup granulated sugar

Instructions

  1. Season the cooked and mashed butternut squash with 1/4 cup butter, 1 tablespoon brown sugar, 1/4 teaspoon salt, and white pepper.
  2. Heat 1 1/2 tablespoons butter in a skillet over low heat; add the sliced unpared Jonathan apples.
  3. Sprinkle the apples with 1/4 cup granulated sugar.
  4. Cover and simmer until the apples are barely tender, about 5 minutes.
  5. Spread the cooked apples evenly in a 3-quart casserole dish.
  6. Spoon the seasoned mashed squash over the apples.
  7. Mix cornflakes with pecans, 1/2 cup brown sugar, and melted butter to make the streusel topping.

  9. Bake in a preheated 350°F oven for 15 minutes until golden.

Tips & Substitutions

For a richer flavor, try adding a pinch of nutmeg or cinnamon to the butternut squash mixture. If Jonathan apples aren't available, consider using Granny Smith or Honeycrisp for a similar tartness. You can also substitute the granulated sugar with maple syrup for a unique twist. To make this dish gluten-free, use gluten-free cornflakes in the streusel topping.

Frequently Asked Questions

Can I prepare this casserole ahead of time?

Yes, you can prepare the casserole a day in advance. Assemble it up to the baking step, then cover and refrigerate. When ready to bake, allow it to sit at room temperature for about 30 minutes before placing it in the oven. This will ensure even cooking and prevent cracking.

What can I use instead of butter in the recipe?

If you're looking for a dairy-free option, you can substitute the butter with coconut oil or a plant-based butter alternative. The flavor will slightly differ, but it will still create a deliciously moist casserole. Just ensure that the substitute is suitable for baking and has a similar fat content.

How do I make the casserole vegetarian?

This recipe is already vegetarian, but to enhance the nutrition, you can add cooked lentils or chickpeas for added protein. Additionally, feel free to incorporate vegetables like spinach or kale into the butternut squash layer for an extra nutrient boost.
