A cozy, one-pot cream of potato soup recipe packed with extra protein for a macro-friendly comfort meal.

Ingredients

Scale
  • 2 lbs Russet potatoes, peeled and cubed
  • 1 large yellow onion, chopped
  • 4 cups low-sodium chicken or vegetable broth
  • 1 cup skim milk or high-protein milk alternative
  • 1 cup low-fat cottage cheese
  • 1/2 cup plain Greek yogurt (2% or non-fat)
  • 2 tablespoons butter or olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt (or to taste)
  • 1/4 teaspoon black pepper
  • 2 tablespoons cornstarch mixed with 2 tablespoons cold water (slurry)

Instructions

  1. Melt butter or heat oil in a large pot or Dutch oven over medium heat. Add onion and cook until soft, about 5 minutes.
  2. Add minced garlic and dried thyme. Cook for 1 minute until fragrant.
  3. Add cubed potatoes and broth to the pot. Bring the mixture to a boil, then reduce heat, cover, and simmer for 15-20 minutes, or until potatoes are very tender.
  4. Remove the pot from the heat. Use an immersion blender to blend the soup until mostly smooth, leaving some small chunks for texture if you prefer. Alternatively, carefully transfer batches to a standard blender and return to the pot.
  5. Stir in the skim milk, cottage cheese, and Greek yogurt until fully incorporated and smooth. Return the pot to low heat. Do not boil after adding dairy.
  6. Whisk the cornstarch slurry and slowly pour it into the soup while stirring constantly. Heat gently until the soup thickens slightly, about 2-3 minutes.
  7. Season with salt and pepper to taste. Serve hot.

Notes

  • For meal prep, cool the soup completely before dividing it into individual containers. It reheats well on the stovetop or in the microwave.
  • If you want a richer flavor, use roasted garlic instead of fresh garlic.
  • This recipe uses cottage cheese for a significant protein boost; blend well for the smoothest texture.
