How to Make Acorn Squash Feta Casserole

  1. Preheat oven to 375°F (190°C).
  2. Cut 1 medium acorn squash in half lengthwise.
  3. Remove seeds and stringy pulp from the squash halves.
  4. Place squash halves cut-side down in a greased 15x10x1-inch baking pan.
  5. Bake for 35-40 minutes, or until tender.
  6. Let cool slightly, then carefully scoop out the cooked squash flesh into a large bowl and mash.
  7. While squash bakes, melt 2 tablespoons of butter in a skillet over medium heat. Add 1/2 cup chopped onion and 2 cloves minced garlic. Saute until softened, about 5 minutes.
  8. Add 1/2 cup chopped bell peppers (any color) and saute until crisp-tender, about 5 more minutes.
  9. In a separate bowl, whisk together 3 large eggs and 1/2 cup plain Greek yogurt until light and fluffy.
  10. Stir in the mashed squash, sauteed onion and pepper mixture, 4 ounces crumbled feta cheese, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and a pinch of cayenne pepper (optional).
  11. Transfer the mixture to a greased 11x7x2-inch baking dish.
  12. Sprinkle 1/4 cup sunflower seeds over the top.
  13. Cover the baking dish with foil.
  14. Bake for 25 minutes.
  15. Remove foil and bake for another 25-30 minutes, or until a knife inserted near the center comes out clean.
  16. Let cool slightly before serving.

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
