Step‑by‑Step Instructions for Potato Onion Soup

Step 1: Caramelize the Onions
In a large Dutch oven, melt 2 tablespoons of butter and a splash of olive oil over medium heat. Add 2 sliced Vidalia onions with a pinch of salt and sauté, stirring occasionally, until they turn a rich golden brown, about 30-40 minutes. If the onions begin to stick, add a splash of water or broth to keep them from burning and enhance their flavor.

Step 2: Add the Garlic
Once the onions are caramelized, stir in 3 minced garlic cloves and cook for about 1 minute until fragrant. This will infuse the base of your Potato Onion Soup with delicious garlicky aroma, making it even more inviting. Make sure to stir frequently to prevent the garlic from browning too quickly.

Step 3: Deglaze the Pan
Pour in ½ cup of dry white wine (or additional broth) to deglaze the pot, scraping up any delicious browned bits stuck to the bottom. Allow the mixture to simmer for about 3-5 minutes until the liquid has mostly absorbed, creating a rich foundation for your soup.

Step 4: Cook the Potatoes
Add 4 diced Yukon gold potatoes to the pot, then pour in 4 cups of broth—using chicken bone or vegetable broth—along with salt and pepper to taste. Stir in 1 bay leaf, 1 teaspoon of fresh thyme, and 1 teaspoon of fresh rosemary. Bring the soup to a gentle boil, then reduce the heat and simmer for about 20 minutes until the potatoes are fork-tender.

Step 5: Blend the Soup
After the potatoes are cooked through, remove the bay leaf and add the juice of 1 lemon for a bright flavor. Use an immersion blender to blend the soup until smooth; you can also transfer it to a countertop blender in batches. Adjust the consistency by adding water or broth as desired for your preferred thickness.

Step 6: Serve and Garnish
Ladle the creamy Potato Onion Soup into warm bowls, drizzling with extra virgin olive oil for a touch of richness. Garnish with fresh herbs like rosemary or thyme for a pop of color and flavor. Pair it with crusty bread or a light salad for a wholesome, heartwarming meal.

How to Store and Freeze Potato Onion Soup

Fridge: Store the soup in an airtight container for up to 5 days. Allow it to cool completely before sealing to maintain freshness and avoid condensation inside.

Freezer: Freeze the soup in a freezer-safe container for up to 6 months. Ensure to leave some space at the top for expansion, and label with the date for easy reference.

Reheating: When ready to enjoy, thaw overnight in the fridge. Reheat gently on the stove, adding a splash of broth to help loosen the consistency if necessary, ensuring your Potato Onion Soup is warm and creamy.

Avoid Refreezing: For the best flavor and texture, do not refreeze the soup once it has been thawed. Enjoy it fresh for a comforting meal anytime!

Make Ahead Options

These Creamy Potato Onion Soup preparations are perfect for busy evenings! You can caramelize the onions and garlic up to 24 hours in advance, storing them in an airtight container in the refrigerator to preserve their rich flavor. Alternatively, you can fully cook the soup and refrigerate it for up to 5 days. This allows the flavors to deepen and meld beautifully. When you’re ready to enjoy, simply reheat the soup gently on the stove, adding a splash of broth or water for consistency. This make-ahead approach ensures you have comforting, homemade soup on hand, saving you time without compromising on quality!

Expert Tips for Potato Onion Soup
