If you’re a fan of French Onion Soup, then you’ll probably like this Caramelized Onion Soup too. Caramelized onions are sweet and melt-in-your-mouth wonderful, so translate that into soup and that’s what we’ve got here. It’s a smooth, blended soup with great fall flavors.

Ingredients needed for Caramelized Onion Soup:

yellow onions butter olive oil beef broth fresh apple cider fresh thyme white sugar Parmesan cheese

How to make cider syrup:

The cider syrup used in this recipe is made using the simple process of reducing apple cider by boiling it in a saucepan. You’ll start with 2 cups of apple cider and boil that down to 1/3 cup, which will result in a syrup-like consistency.

How to Caramelize Onions:

Butter and oil are heated together in the soup pot. Thinly sliced yellow onions are added to the pot. Since onions break down a lot when cooked, you’ll be using a lot of onions (about 5). The onions are cooked over medium-high heat for about 20 minutes. Stir them often, and they’ll start turning brown and shrivel up as it shows in the photo above.

How to turn caramelized onions into soup:

After you’re done caramelizing the onions, you’ll add beef broth and apple cider to the onions in the pot. Then you’ll add several fresh thyme sprigs, a tiny bit of sugar and salt/pepper. The soup is then simmered for 30 minutes. Once the simmering is done, you’ll want to pull it off the heat and let it cool off a bit. Then you’ll process all of it in a food processor until it’s smooth in texture.

Garnish bowls of soup with a drizzle of the cider syrup, a sprinkle of Parmesan cheese and a few fresh thyme leaves.

What to serve with caramelized onion soup:

Pick up the best crusty French bread you can find in your town. It’ll be good for dunking in this delicious soup! Serve it with a side salad and some white wine. Or you can opt to serve Caramelized Onion Soup in cups as a side to roasted chicken or pork. It’s even a nice little starter for your Thanksgiving dinner. Enjoy!
