Best Simple Caramelized Onion Potato Soup Recipes

CARAMELIZED ONION AND POTATO SOUP

Steps:

• Heat the oil in a pressure cooker (without lid) over medium heat. Add the onions and cook for quite a long time to caramelize. The exact timing will depend on how sweet your onions are. Mine weren't sweet at all so the process took about 40 minutes. The way to caramelize is to cook the onions slowly over medium heat - perhaps adding a bit of veggie broth if they start to stick to the pan. You're looking for a nice deep brown color both on the onions and on the pan- that's the sugar coming out of the onion.
• After the onions are nice and brown and the bottom of the pan is looking very brown add the potatoes. Stir and cook for about 5 minutes - to give the potatoes a bit of that nice roasted flavor.
• Cover with the veggie broth. Raise the heat to high and lock on the pressure cooker lid. Bring to high pressure, then immediately turn off the heat. Allow the pressure to reduce naturally. Remove lid.
• Using an immersion blender, blend the soup thoroughly. Serve immediately - maybe with some nice crusty bread.

FLORENTINE CARAMELIZED ONION SOUP

Steps:

• In a large heavy pot, heat oil over medium heat. Cut onions in half lengthwise, then slice thinly. Place sliced onions in pot and toss to coat with oil. Cover, reduce heat to medium-low, and cook, stirring occasionally, until onions are softened and beginning to color, 30 minutes.
• Increase heat to medium and cook, stirring occasionally, uncovered, until onions are amber in color, 45 minutes.
• Sprinkle onions with sugar and a little bit of salt; cook, stirring, until sugar melts and onions are caramel colored, 5 minutes. Pour in wine and broth, and place cinnamon stick in pot. Bring to a boil, then reduce heat, cover and simmer 1 hour.
• Stir the bread into the soup and cook, uncovered, stirring occasionally until the bread disintegrates, 30 to 45 minutes.
• Remove the cinnamon stick. Whisk the soup to incorporate the bread. Adjust seasoning. Serve hot.

CREAMY CARAMELIZED-ONION SOUP

Steps:

• Melt 4 tablespoons butter in a large saucepan over medium heat. Add leeks, garlic, shallots, and half of the onions. Cook, stirring occasionally, until vegetables are very soft and translucent, about 10 minutes. Reduce the heat to medium-low, and cook, stirring occasionally, until vegetables are deep golden brown, about 25 minutes.
• Add vermouth, stock, and 1 teaspoon salt. Bring to a boil. Reduce heat to medium-low. Simmer, stirring occasionally, 15 minutes. Let cool. Puree onion mixture in batches in a blender until smooth, about 3 minutes per batch. Set aside.
• Meanwhile, melt remaining 2 tablespoons butter in a medium skillet over medium-low heat. Add remaining onion. Cook, stirring occasionally, until onion is very soft and golden brown, about 45 minutes. Cover, and set aside.
• Return onion puree to saucepan. Stir in cream. Reheat over medium heat, stirring, until heated through but not boiling. Season with salt, if desired. Serve, topped with caramelized onions.

SIMPLE CARAMELIZED ONION POTATO SOUP

Steps:

• Peel potatoes and dice into large chunks (this helps them cook faster) and chop celery.
• Add both into soup pot with the chicken broth. Simmer until veggies are tender and potatoes can be easily pierced with a fork, about 25 minutes.
• While your veggies are simmering, in a separate pan, add the chopped onions along with butter. Cook them very low and slow, stirring frequently so they don't burn or brown, but develop a deep caramel color, for 15-25 minutes.
• In the last 5 minutes or so, add the chopped garlic, and cook for the remaining few minutes.
• When your potatoes and celery are done, add the caramelized onions and garlic to the pot, and transfer to a food processor or blender. Blend until smooth. Return blended soup to the pot.
• Add milk or cream to finish, based on your preferences and desired thickness and creaminess.
• Serve immediately, garnished with parmesan and chopped chives!
