  5. Add the well-drained sliced squash to the sour cream and soup mixture.

  6. Spoon the squash mixture into the prepared baking dish.

  • If you don't have stuffing mix, make homemade herb seasoned crumbs. Tear or cut 2 to 3 slices of bread into small pieces or process to make coarse crumbs. Spread the crumbs or pieces out on a baking sheet. Bake in a 350 F oven until dry and crusty. Toss the crumbs with 1 teaspoon of celery flakes, 1/4 teaspoon of onion powder, 1/2 teaspoon of poultry seasoning, and a dash of freshly ground black pepper. If desired, add 1 teaspoon of dried parsley flakes.
