Tips For Classic Sweet Potato Casserole

  • Gluten-Free Comfort Casserole: Substitute all-purpose flour with almond flour or gluten-free flour blend in the streusel topping to make the recipe celiac-friendly.
  • Nut-Free Autumn Bake: Eliminate pecans from the streusel and replace with pumpkin seeds or sunflower seeds for those with nut allergies.
