Tips & Substitutions

For a creamier texture, consider adding a bit of cream cheese or using Greek yogurt as a substitute for sour cream. If yellow squash is unavailable, zucchini works well too. Adding breadcrumbs on top before baking can give a delightful crunch. For an herb twist, try incorporating fresh thyme or oregano alongside dill weed.
