  • 1 tablespoon basil
  • 6 cups sliced potatoes

  2. Microwave at 50% power for about 4 minutes, then stir.
  3. Place half of the sliced potatoes in a sprayed casserole dish.
  4. Add half of the sauce over the potatoes.
  5. Repeat with remaining potatoes and sauce.

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.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and warm it in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through. You can also microwave individual portions, but be sure to cover them to retain moisture.

Is this dish suitable for vegetarians?
