  • Fork
  • Potato Masher (optional)
  • Blender (optional)

Ingredients
  

Main Ingredients

  • 2 lbs Yukon Gold or Russet potatoes peeled and diced into 1-inch cubes
  • 1 large yellow onion
  • 2 stalks celery
  • 2 cloves garlic
  • 4 cups low-sodium vegetable broth (or chicken broth if preferred)
  • 1 tsp dried thyme
  • 1/2 tsp dried rosemary
  • 1/2 tsp onion powder
  • 1/4 tsp black pepper
  • Salt to taste
  • 1 cup unsweetened almond milk (or oat milk for extra creaminess)
  • 1/2 cup plain Greek yogurt (full-fat for richness, or 0% for lighter)
  • 2 tbsp cornstarch (mixed with 2 tbsp cold water to create a slurry)
  • 1 tbsp olive oil

Optional Garnish

  • Fresh chives, a sprinkle of smoked paprika, or a dollop of extra Greek yogurt

Instructions
 

Preparation

  • Peel and dice the potatoes, onion, and celery, then mince the garlic.

Cooking

  • In a skillet, sauté onion and celery in olive oil for 5-7 minutes until soft, then add minced garlic and cook for 1 minute.
  • Transfer sautéed vegetables (or raw) to a slow cooker, add potatoes, broth, and seasonings, then stir.
  • Cover and cook on LOW for 6-8 hours or HIGH for 3-4 hours, until potatoes are tender.
  • Whisk cornstarch with cold water to create a slurry, then pour into the slow cooker and stir well.
  • Stir in almond milk and Greek yogurt, then cook on HIGH for another 30-60 minutes until thickened.
  • Mash some potatoes in the slow cooker for a chunky soup, or carefully blend half for a smoother consistency.
  • Adjust seasoning with salt and pepper, then serve hot with desired garnishes.

Notes

For a richer soup use full-fat Greek yogurt. If you prefer a completely smooth soup, blend all of it. Be careful when blending hot liquids, only fill the blender half-way and vent the lid.
