Set a Dutch Oven pot or soup pot over medium hot heat. Add olive oil, butter, and salt to heat.
1 tablespoon olive oil
1 tablespoon butter
1/2 teaspoon kosher salt
Trim, thoroughly rinse and thinly slice two large leeks. Set aside a slice or 2 for garnish. Add to hot oil and cook until tender, adjusting temperature as needed to avoid burning. Stir often.
2 large leeks
Peel and dice two russet potatoes. Add stock to pot and stir to lift any leek stuck to bottom of pot. Add potatoes and cover. Reduce heat to simmer and cook 30 minutes.
1 large russet potato
2 cups low sodium vegetable broth
In pot, use immersion blender to puree soup. Move blender up and down and then round and round. It is quite achievable to have a nice creamy puree with a hand blender. Add half and half and stir in.
1/4 cup half and half cream
Add salt and pepper to taste and top individual portions with grated cheddar cheese.
