French Onion Chowder

Two soups collide in this French Onion Chowder. Sliced sweet onions are slowly cooked until caramelized and tender, then they’re combined with fresh thyme, garlic and potatoes and simmer in a creamy rich parmesan broth. This recipe yields 10 cups or serves about 6 (1½ cup) servings.

French Onion Chowder

I’ve waited for the Michigan weather to get its act together so I can declare soup season.

And now that the weather has dipped ever so slightly to the cooler side, I make one soup a week at the least. Six years ago I morphed two of my favorite recipes together in order to create this gorgeous and lusciously rich soup. First of all, who doesn’t love caramelized onions? Onions slowly cooked until the sugars are released and caramelize. Now imagine those rich and flavorful caramelized onions along with tender potatoes, garlic and fresh thyme in a creamy parmesan broth.

It’s everything I love in life and basically heaven in a bowl.

Then cover and heat on medium-high bringing the soup to a low-boil. Next uncover the pot, reduce the heat to medium to medium-low and cook for 20 to 25 minutes OR until the potatoes are thoroughly cooked through and soup has thickened.

Furthermore, I’ve made this a few times and if the soup doesn’t thicken up enough or (more likely) I’m lacking in patience, I will make a cornstarch slurry. Typically I mix up 2 tablespoons cornstarch mixed with 2 tablespoons water and stir it into a bubbling soup.
