Tips & Substitutions
For a creamier texture, consider adding a splash of heavy cream or using whole milk instead of skimmed milk. You can also substitute the Grey Poupon mustard with Dijon mustard if desired. To save time, use pre-sliced potatoes or even frozen hash browns for a quicker assembly. If you prefer a more robust flavor, add minced garlic or swap in fresh herbs like thyme instead of basil.
Serving Suggestions
Potato Poupon is a delightful main dish that pairs well with a simple green salad or steamed vegetables for a balanced meal. For a hearty side, consider serving it alongside Texas Hominy Grits Casserole. You can also top it with additional herbs or a sprinkle of paprika for added color and flavor before serving.
