Step‑by‑Step Instructions for Nourishing Potato Onion Soup
Step 1: Heat the Base
Begin by placing a large Dutch oven over medium heat and adding 2 tablespoons of butter along with 1 tablespoon of olive oil. Allow the butter to melt completely, creating a rich base for your nourishing Potato Onion Soup. This should take about 1-2 minutes, and you’ll hear a gentle sizzle as the fats meld together.
Step 2: Caramelize the Onions
Next, add 2 sliced Vidalia onions and a pinch of kosher salt to the pot. Stir to coat the onions in the melted butter and oil, then reduce the heat slightly. Cook for about 40-50 minutes, stirring occasionally, until the onions are soft, golden brown, and caramelized, releasing their sweet aroma.
Step 3: Add Garlic for Aroma
Once the onions are beautifully caramelized, add 3 minced garlic cloves to the pot. Sauté for 1 minute until fragrant, stirring constantly to prevent burning. This addition will elevate the flavor profile of your nourishing Potato Onion Soup, creating a delightful aromatic base.
Step 4: Deglaze with Wine
Deglaze the pan by pouring in 1/2 cup of dry white wine. Stir frequently as the liquid cooks down for about 3-5 minutes, scraping up any browned bits from the bottom of the pot. The wine adds a layer of acidity and depth that enhances the overall flavor of the soup.
Step 5: Introduce the Potatoes
Now, add 4 diced Yukon Gold potatoes to the pot, followed by 4 cups of broth, 1 teaspoon of kosher salt, 1/2 teaspoon of ground pepper, and 2 sprigs of fresh rosemary and thyme. Stir everything together and bring the mixture to a boil; once boiling, reduce the heat and let it simmer for about 20 minutes, or until the potatoes are tender.
Step 6: Remove Herbs and Add Lemon
After simmering, carefully remove the herb stems and bay leaf from the pot. Squeeze in the juice of 1 fresh lemon, mixing well. This will brighten the flavors of your nourishing Potato Onion Soup, giving it a refreshing finish.
Step 7: Blend to Perfection
Using an immersion blender, carefully blend the soup until it’s smooth and creamy. If you prefer a thinner consistency, add water gradually until you reach your desired thickness. The blending will transform your soup into a silky texture, embodying the warmth and comfort it promises.
Step 8: Serve and Garnish
Ladle the nourishing Potato Onion Soup into bowls and consider adding a drizzle of extra virgin olive oil for depth. For a beautiful finish, sprinkle fresh herbs on top. Serve warm, perhaps alongside a crusty piece of bread, to fully enjoy this delightful, hearty dish!
