Prep and Cook Time

• Preparation: 15 minutes
• Cooking: 45 minutes
• Total Time: 1 hour

Yield

• Serves 6 generous bowls

Difficulty Level

• Easy to Medium – approachable for beginners yet satisfying for seasoned cooks

Ingredients

• 4 large russet potatoes, peeled and diced (about 4 cups)
• 3 large yellow onions, thinly sliced
• 4 tablespoons unsalted butter
• 3 cloves garlic, minced
• 4 cups vegetable broth, low sodium
• 2 cups whole milk (or substitute with almond or oat milk for dairy-free)
• 1 teaspoon fresh thyme leaves
• Salt and freshly ground black pepper, to taste
• 2 tablespoons all-purpose flour (for thickening)
• Chopped chives or fresh parsley for garnish
• Optional: shredded sharp cheddar cheese for topping

Instructions

1. Caramelize the onions: In a large heavy-bottomed pot, melt the butter over medium heat. Add the sliced onions and a pinch of salt. Sauté slowly for 25-30 minutes, stirring occasionally until the onions turn a deep golden brown. This step is crucial for developing the soup’s signature sweetness and depth.
2. Incorporate garlic and flour: Add minced garlic and cook for 1 minute until fragrant. Sprinkle the flour over the onions and stir well to create a roux, cooking for an additional 2 minutes. This thickens the soup and gives it a silky texture.
3. Add potatoes and broth: Pour in the diced potatoes and vegetable broth. Toss in the fresh thyme leaves. Bring the mixture to a gentle boil, then reduce heat and simmer covered for 20-25 minutes, until potatoes are soft and tender.
4. Blend to creamy perfection: Use an immersion blender to purée the soup directly in the pot, or carefully transfer batches to a blender. Purée until smooth but leave a few chunks if you prefer texture. Return to pot if needed.
5. Stir in milk and adjust seasoning: Slowly add the milk while stirring to prevent curdling. Heat through on low and taste, seasoning with salt and freshly ground pepper.
6. Final simmer: Let the soup simmer gently for another 5 minutes to marry the flavors and develop that luscious, creamy consistency.

Tips for Success

• Patience with onions: Don’t rush caramelizing – it’s the cornerstone of flavor depth. If onions start to burn, lower the heat and stir more frequently.
• For extra creaminess: Add a splash of heavy cream or coconut milk when stirring in the milk, especially if using plant-based alternatives.
• Make ahead: This soup tastes even better the next day. Reheat gently, stirring occasionally and adding a splash of broth or milk to revive creaminess.
• Variations: Swap russet potatoes for Yukon Gold for a buttery flavor or add sautéed mushrooms for earthiness.

Serving Suggestions

Serve this comforting soup hot in rustic bowls, topped with a sprinkle of fresh chopped chives or parsley for a burst of color. A dollop of sour cream or a handful of shredded sharp cheddar cheese melts beautifully on top, adding an indulgent touch.

Pairs exquisitely with a crisp green salad or warm cornbread for a complete Southern-inspired meal that nourishes both body and soul. For a textural contrast, drizzle a little extra virgin olive oil or a few chili flakes if you desire a subtle spice kick.
