  • Instant Pot


  • 1 1/2 pound Russet potatoes washed, peeled and cut into 1 inch pieces
  • 1 medium head of cauliflower (about 3-4 cups) washed and cut into florets
  • 1 cup broth
  • 1 tsp salt or to taste
  • 2-3 cloves garlic peeled, or to taste
  • 2 tbsp coconut oil, olive oil or butter or to taste (for Whole30 or Paleo, use coconut or olive oil)
  • 1/4 cup plain yogurt, sour cream or full fat coconut milk for a dairy-free option (for Paleo or Whole30, use coconut milk)
  • black pepper to taste
  • freshly chopped herbs like parsley, chives or rosemary optional


  • In your Instant pot, combine cauliflower, potatoes, broth, salt, garlic and herbs (if using)
  • Place the lid on you Instant Pot and lock it into place. Make sure the valve is switched to sealing.
