onion
  • 1 onion diced
broth
  • 4 cup chicken broth
cream
  • 1.5 cup heavy cream
butter
  • 3 tbsp unsalted butter
olive oil
  • 1 tbsp olive oil for roasting the garlic
cheddar
  • 2.5 cup shredded sharp cheddar
thyme
  • 1 tsp fresh thyme leaves
chives
  • 1 tbsp fresh chives chopped
rosemary
  • 1 tbsp fresh rosemary chopped
salt
  • 1 tsp salt
black pepper
  • 0.5 tsp black pepper

Equipment

  • 1 Dutch oven

Method
 

Roast the garlic
  1. Heat oven to 400F. Roast garlic cloves with 1 tablespoon olive oil for 20 minutes until golden and soft.
  2. Cool the roasted garlic, then mash it into a paste.
Build the soup
  1. Melt the butter in a large pot, then sauté the diced onion for 5 minutes.
  2. Add the mashed roasted garlic and cook for 1 minute.
  3. Pour in the chicken broth and add the cubed potatoes, then simmer for 20 minutes until very tender.
  4. Blend the soup smooth with an immersion blender, then stir in the heavy cream.
  5. Reduce heat to low and stir in the shredded sharp cheddar until fully melted.
  6. Stir in thyme, rosemary, and chives, then season with salt and black pepper.

Notes

For the creamiest texture, blend while the soup is hot but keep it at low splatter speed with the immersion blender. Store leftovers in the refrigerator up to 3 days; reheat gently on the stove so the cheese stays smooth. Freezing is not recommended because potatoes can turn grainy after thawing. For a lighter option, use half-and-half instead of heavy cream (texture will be slightly thinner).
