  • 4 Large Potatoes
  • 1 Tbs Salt

For Caramalized Onions

Assembling

  • 3 tbs Parsley (chopped)

Instructions

Preparation:

  • Peel and cutpotatoes in 1 inch cubes, rinse in cold water.
  • Peel and thinly slice onions. Next chop parsley and set aside.

Cook the Potatoes:

  • Place potato cubes in a pot, cover with cold water, and add salt.

  • Add sliced onions and a pinch of salt.
  • Cook for 20-25 minutes, stirring occasionally, until soft and golden.Add a splash of water or more oil if onions stick to the pan.

Mash the Potatoes:

  • Mash cooked potatoes until smooth and creamy. For ultra-smooth texture, press through a sieve (optional).

Combine Onions and Potatoes:

  • Add vegan butter and non-dairy milk to the potatoes.
  • Season with salt and pepper. Fold in caramelized onions evenly, adding more milk if needed. Avoid overmixing.
  • Garnish with chopped parsley or chives.Serve hot and enjoy!

Notes

  • Cook onions over low to medium heat to avoid burning and to allow natural sugars to develop.
  • If onions start to stick, add a splash of water, vegetable broth, or more oil to deglaze the pan.
  • Use starchy potatoes like Russets or Yukon Golds for a fluffy texture.
  • Mash potatoes while they are still warm for a smoother texture.
  • Mix the caramelized onions into the mashed potatoes while they are still warm to enhance the overall flavor.
