Herbed Potato And Peas Mash

Yield: 4-6 servings

Prep Time: 10 minutes

Sous Vide Cooking Time: 

1-2 hours

Recipe Type: Side, Easy, Gluten-Free


  • 1 steak (about 10oz/280g), 1-inch thick
  • 1lb/450g potatoes, peeled and cut into 1/2 to 3/4-inch evenly-sized chunks
  • 2-3 whole garlic cloves, peeled
  • 1 1/2 tablespoons olive oil, divided
  • 3 fresh sage leaves
  • 2 fresh thyme sprigs
  • Salt and freshly ground black pepper, to taste
  • 1 cup/5 oz/ 140g frozen peas
  • 2 tablespoons butter
  • ½ cup milk (more as needed)



Insert your Saki Sous Vide Cooker into a pot (or another sous-vide -friendly container) and fill the pot with water between the MIN and MAX marks. Set the temperature to 186°/85.5°C.


While the water is heating, in a large bowl, mix together potatoes, garlic cloves, 1 tablespoon olive oil, sage and thyme; season to taste. Transfer the potatoes to a gallon freezer zip-lock bag (or use a vacuum-sealing bag). Place 2 heavy dessert spoons in the bag to prevent the potatoes from floating.


Add the peas and the remaining ½ tablespoon olive oil to a zip-lock (or vacuum-sealing bag) and season to taste. To prevent the bag from floating, place 2 heavy dessert spoons in the bag.


When the water temperature is reached, insert the bags into the water or clip onto the side of the container. If using zip-lock bags, remove air using the water displacement method by slowly submerging the bags in the water, then sealing. Set the time to 45 minutes.


When the time is up, remove the peas and place the bag in ice water to cool; set aside.


Add 45 minutes cooking time for the potatoes and when the time is up, remove the bag from the water and check the potatoes for doneness. If needed, return to the pot and cook for additional 15-30 minutes. Transfer the potatoes to a bowl and discard the sage, thyme and garlic.


Melt the butter in a large saucepan over a medium heat; add the potatoes and peas. Using a potato masher, mash together, adding splashes of milk as necessary, to get the desired consistency. Adjust seasoning to taste and serve.
