#1 Hearty Leftover Mashed Potato Muffin Recipe

Muffins don’t always have to be sweet, and they make a tasty snack between meals. While it may not sound conventional, muffins are a great way to use up leftover mash. 

Ingredients:

  • 3 green onions
  • 1 lb. leftover mashed potatoes
  • ¾ cup grated Cheddar or Gouda cheese
  • 1 cup grated hard cheese (e.g. Parmesan)
  • ¾ cup crème fraîche
  • Salt and pepper
  • Butter or oil to grease the muffin tin

Preparation:

  1. Wash the spring onions and chop them finely.
  2. Put the mashed potato in a bowl and mix with the chopped spring onions, cheese and crème fraîche.
  3. Season the mixture with salt and pepper.
  4. Grease a muffin tray with a little butter or oil, for example rapeseed oil, and distribute the muffin mixture evenly in the trays.
  5. Bake the mashed potato muffins for 20 to 25 minutes at 400˚F. You don’t need to preheat the oven, just check the browning of the muffins from time to time and take them out when they look to your liking.

For vegetarian muffins, you’ll have to skip the Parmesan (Parmesan isn’t vegetarian as it contains animal rennet). However, you can replace it with homemade vegan Parmesan.
For vegan muffins, you’ll need vegan replacements for both kinds of cheese and the crème fraîche.
