Roasted Garlic Cheddar Potato Soup

Roasted Garlic Cheddar Potato Soup is thick, creamy, and full of cozy flavor without needing to blend the whole pot. Yukon Gold potatoes simmer until tender, then a portion gets gently mashed right into the broth to give the soup natural body while leaving plenty of soft potato pieces in every spoonful.

The roasted garlic is what makes this version different. Roasting mellows the cloves and brings out their sweeter, deeper flavor before they are stirred into the soup with sharp cheddar, sour cream, and a little Dijon. Bacon adds a smoky, salty contrast without taking over the potatoes.

Freshly shredded cheddar melts in after the pot comes off the heat, keeping the broth smooth instead of grainy. Finish each bowl with crisp bacon, chives, a little extra cheddar, and a spoonful of sour cream. It is familiar potato soup with one extra layer of flavor that makes it especially good for the first cool nights of fall.

Recipe Yield: 6 servings

INGREDIENTS

4 cups low-sodium chicken broth
2 1/2 lbs Yukon Gold potatoes, cut into 3/4-inch pieces
6 slices thick-cut bacon, chopped
1 medium yellow onion, finely diced
2 celery ribs, finely diced
1 whole garlic bulb
2 cups freshly shredded sharp cheddar cheese, divided
1/2 cup sour cream, plus more for serving
1 cup whole milk
1/2 cup heavy cream
3 tbsp unsalted butter
1 tsp olive oil
1/4 cup all-purpose flour
1 tsp kosher salt
1/2 tsp black pepper
1/2 tsp dried thyme
1 tsp Dijon mustard
3 tbsp chopped fresh chives, divided

INSTRUCTIONS

1. Roast the garlic:
Preheat the oven to 400°F. Slice about 1/4 inch from the top of the garlic bulb to expose the cloves. Drizzle with olive oil, place cut-side up in a small covered baking dish, and roast for 35–40 minutes, until the cloves are very soft and lightly golden.

2. Cook the bacon:
Meanwhile, add the bacon to a large Dutch oven or heavy pot over medium heat. Cook for 7–9 minutes, stirring occasionally, until crisp. Transfer the bacon to a paper towel-lined plate, leaving about 1 tbsp bacon drippings in the pot.

3. Soften the vegetables:
Add the onion and celery to the pot. Cook over medium heat for 5–6 minutes, stirring occasionally, until softened but not browned.

4. Build the soup base:
Add the butter. Once melted, sprinkle in the flour and cook for 1 minute, stirring constantly. Slowly whisk in the chicken broth until smooth.

5. Simmer the potatoes:
Add the potatoes, salt, black pepper, and thyme. Bring to a gentle boil, then reduce the heat to medium-low. Cover partially and simmer for 15–18 minutes, stirring occasionally, until the potatoes are completely fork-tender.

6. Add the roasted garlic:
Squeeze the softened roasted garlic cloves from their skins into a small bowl and mash until smooth. Stir the roasted garlic into the soup.

7. Thicken naturally:
Use a potato masher to gently mash about one-third of the potatoes directly in the pot, leaving the remaining pieces intact. Stir until the broth becomes naturally creamy and slightly thickened.

8. Finish the soup:
Reduce the heat to low. Stir in the milk, heavy cream, and Dijon. Heat gently for 2–3 minutes without boiling, then remove the pot from the heat.

9. Add the cheddar:
Stir in 1 1/2 cups cheddar a handful at a time until completely melted and smooth. Fold in the sour cream, half of the cooked bacon, and 2 tbsp chives.

10. Serve the soup:
Ladle into bowls and finish with the remaining 1/2 cup cheddar, bacon, remaining 1 tbsp chives, and a small spoonful of sour cream.

Helpful Tips to Perfect This Recipe

• Roast the garlic until completely soft: The cloves should squeeze easily from their skins. Properly roasted garlic tastes mellow and slightly sweet rather than sharp.
• Mash only part of the potatoes: Breaking down about one-third naturally thickens the broth while keeping plenty of tender potato pieces for a hearty texture.
• Take the pot off the heat before adding cheddar: High heat can make cheese separate or become grainy. Adding freshly shredded cheddar off heat keeps the soup noticeably smoother.
• Keep the dairy below a boil: Once the milk, cream, and sour cream are added, gentle heat protects the creamy texture and prevents separation.
