Ingredients List

• 2 cups rustic sourdough bread, hand-torn (approximately 1/2-inch pieces)
• 6 tablespoons olive oil, divided, plus extra for drizzling
• 3/4 teaspoons kosher salt, divided, plus more to taste
• 1/2 teaspoon black pepper, divided, plus more for garnish
• 1 head of garlic
• 2 pounds yellow onions (about 4 onions), cut into 1-inch wedges
• 1/4 cup dry white wine
• 1/2 cups chicken stock, warmed (more may be added as needed)
• 1/2 ounce Parmesan cheese, finely grated (approximately 1/3 cup)
• 1/2 cup heavy cream
• 2 tablespoons unsalted butter, cubed

Cooking Instructions

Start by preheating your oven to a warm 400°F (200°C). On a rimmed baking sheet, combine the hand-torn sourdough pieces with 3 tablespoons of olive oil, 1/2 teaspoon of kosher salt, and 1/4 teaspoon of black pepper. Bake for about 8 to 10 minutes, or until the bread turns a delightful golden brown, stirring occasionally. Once ready, transfer the croutons to a bowl and set aside. Wipe the baking sheet clean, but keep the oven on.

Next, take your garlic head and slice off the top 1/2-inch, discarding that section. Place the garlic head, cut side down, along with the onion wedges on the baking sheet. Drizzle the remaining olive oil over them, and gently sprinkle with 3/4 teaspoon of salt and 1/4 teaspoon of pepper. Roast them in the oven for about 30 to 35 minutes until the onions and garlic are tender and slightly browned. Once done, pour the wine over the onions and continue roasting until most of the liquid evaporates—this should take an additional 5 minutes.

Now it's time to blend the goodness! Use tongs to squeeze the softened garlic cloves into a blender, leaving the skins behind. Add the roasted onions along with any remaining liquid from the pan. Pour in the warm chicken stock, grated Parmesan, and the remaining 1/2 teaspoon of salt. Secure the blender lid, removing the center piece to allow steam to escape, and cover with a clean towel. Blend on medium-high speed for about 2 minutes until smooth. Then, decrease to medium-low speed, slowly adding in the cream while the blender runs. Introduce the cubed butter gradually until the soup reaches a splendidly smooth and creamy consistency. If the soup is too thick, feel free to adjust with extra chicken broth, and season to taste with more salt if needed.

Finally, serve this luscious soup in bowls, topping each with croutons and a drizzle of olive oil. Finish with a sprinkle of fresh black pepper, and get ready to enjoy a truly comforting and flavorful experience!

Storage Tips for Longevity

If you have leftovers, store them in an airtight container in the refrigerator for up to three days. Reheating is a breeze—just warm over low heat, stirring occasionally.

For longer storage, freeze the soup before adding cream and butter in an airtight container for up to three months. Just thaw it when ready and heat over low, stirring in the cream and butter just before serving.

Enjoy this comforting soup experience that's perfect for any day of the week!
