Ingredients
  

Cheddar garlic herb potato soup base
  • 3 lb Yukon gold potatoes Peel and cube into 1-inch pieces for even cooking.
  • 1 garlic head Use peeled cloves so they roast evenly.
  • 1 onion Dice finely for quicker sautéing.
  • 4 cup chicken broth Use for simmering until potatoes are tender.
  • 1.5 cup heavy cream Stir in after blending to keep the soup creamy.
  • 3 tbsp unsalted butter Used for sautéing onion and building flavor.
  • 2.5 cup shredded sharp cheddar Add at low heat so it melts smoothly.
  • 1 tsp fresh thyme leaves Leaves only; add near the end to stay fragrant.
  • 1 tbsp fresh chives Chopped; add with herbs for freshness.
  • 1 tbsp fresh rosemary Chopped; add with thyme for an herbal backbone.
  • 1 tsp salt Season to taste in the final step.
  • 0.5 tsp black pepper Season to taste in the final step.

Equipment

  • 1 Dutch oven

Method
 

Roast the garlic
  1. Toss the peeled garlic cloves with 1 tablespoon olive oil and roast at 400F for 20 minutes until golden and soft. Cool briefly, then mash into a paste.
Build the soup
  1. Melt the butter in a large pot, then sauté the diced onion for 5 minutes. Cook until softened and fragrant.
  2. Add the mashed roasted garlic and cook for 1 minute. Stir constantly so it doesn’t burn.
Simmer and blend
  1. Add chicken broth and cubed Yukon gold potatoes, then simmer for 20 minutes until very tender. Keep the simmer steady for even softness.
  2. Blend the soup smooth with an immersion blender, then stir in the heavy cream. Blend until no potato chunks remain.
Finish with cheddar and herbs
  1. Reduce heat to low, then stir in the shredded sharp cheddar until melted. Keep the heat low to prevent graininess.
  2. Stir in thyme leaves, rosemary, and chives, then season with salt and black pepper. Taste and adjust seasoning before serving.

Notes

For the creamiest texture, blend thoroughly right after simmering and before adding cream. Refrigerate leftovers in a sealed container for up to 4 days; reheat gently over low heat, adding a splash of broth if too thick. Freezing is not recommended because cream and potatoes can change texture after thawing. If you want a lighter option, swap heavy cream for half-and-half (texture will be slightly thinner).
