Potato, Apple, and Arugula Soup: A Symphony of Flavors

There’s something truly magical about the first bite of a warm, comforting soup on a chilly evening. I recall one autumn afternoon, wandering through a local farmer’s market, the air crisp and carrying the scent of fallen leaves. A vibrant display of apples and potatoes caught my eye, and inspiration struck. I imagined a soup that wasn’t just sustenance, but a warm hug in a bowl—a dish where the earthiness of potatoes danced with the tart sweetness of apples, all rounded out by the peppery bite of arugula. That’s how my love affair with this Potato, Apple, and Arugula Soup began, a recipe that has since become a staple in my kitchen.

Ingredients

Here’s what you’ll need to create this delightful soup:

• 4 tablespoons unsalted butter

• 1 red onion, diced
• 1 yellow onion, diced
• 1 tablespoon lemon juice
• 4 cups chicken stock (vegetable stock for vegan)
• 2 cups white wine
• 1 lb apple, peeled, cored, and diced (Granny Smith recommended)
• 1 pinch ground allspice
• 1 pinch nutmeg
• 1 teaspoon fresh thyme, chopped
• 2 ounces arugula leaves, soaked and washed thoroughly to remove all grit, stems removed
• 1 teaspoon brown sugar
• Salt & freshly ground black pepper, to taste
• 1 tablespoon chives, chopped, for garnish (optional)
• 2 slices bacon, rinds and all fat removed, cooked and diced, to sprinkle over the soup as a garnish (optional)

Equipment Needed

• Large sauté pan or Dutch oven
• Cutting board
• Sharp knife
• Measuring cups and spoons
• Blender or food processor
• Soup ladle
• Soup bowls

Instructions

Follow these steps to bring this soup to life:

1. Preheat your oven to a low temperature (around 200°F or 93°C). Place your soup bowls and crusty rolls, wrapped in foil, in the oven to warm. This adds a lovely touch, making the dining experience even more comforting.

2. In a large sauté pan or Dutch oven over medium heat, melt the butter. Make sure the pan is large enough to hold all the ingredients comfortably.

3. Add the diced potatoes, diced red onion, and diced yellow onion to the melted butter.

4. Sauté the vegetables for about 5 minutes, stirring constantly to prevent them from sticking or browning too quickly. The goal is to soften them slightly and release their natural flavors.

5. Add the lemon juice, chicken stock (or vegetable stock), white wine, diced apples, ground allspice, nutmeg, and chopped thyme to the pan. The aroma at this stage is simply divine!

6. Bring the soup to a boil over medium-high heat. Once it’s boiling, reduce the heat to a simmer, cover the pan, and cook for 15 minutes. This allows the flavors to meld together beautifully.

7. If you plan to use arugula leaves as a garnish, reserve a small handful now. Add the rest of the arugula leaves and the brown sugar to the soup. Continue to cook for another 10 minutes, or until the potatoes are cooked through and tender. You should be able to easily pierce them with a fork.

8. While the soup is simmering, prepare the bacon (if using). Cook the bacon under the grill (broiler) or in a separate pan until it is crisp. Once cooked, cut it into small pieces (about ½ inch squares) using kitchen scissors and set aside for garnish.

9. Carefully transfer about half of the soup to a blender or food processor. Process for about 1 minute, or until smooth. Important: Be very cautious when blending hot liquids. It’s best to work in batches and vent the blender lid to prevent pressure buildup.

10. Return the blended soup mixture back to the pan. Stir it into the unblended soup to create a lovely creamy texture with some chunky bits for added interest.

11. Season the soup to taste with salt and freshly ground black pepper. Don’t be afraid to be generous with the seasoning – it really enhances the flavors.

12. Ladle the warm soup into the preheated soup bowls.

13. Garnish each bowl with the diced bacon (if using) and either the reserved arugula leaves or chopped chives.

14. Serve immediately with the warm, crusty bread rolls from the oven.

Expert Tips & Tricks

• Potato Choice: While the original recipe called for “waxy potatoes,” a good all-purpose potato like Yukon Gold works beautifully in this soup. They hold their shape well while also contributing to a creamy texture. Avoid Russet potatoes, as they tend to become too starchy.
• Apple Variety: I prefer Granny Smith apples for their tartness, which balances the richness of the soup. However, you can experiment with other varieties like Honeycrisp or Fuji for a sweeter flavor profile.
• Blending for Texture: Blending only half the soup ensures a delightful combination of creamy smoothness and chunky bites, adding complexity to the overall texture. If you prefer a completely smooth soup, blend it all.
• Arugula Timing: Adding the arugula towards the end of cooking preserves its peppery bite. If you add it too early, it will wilt and lose its distinctive flavor.
• Make-Ahead Tip: This soup can be made a day or two in advance. The flavors actually deepen and meld together over time. Store it in an airtight container in the refrigerator and reheat gently before serving.
• Vegan Adaptation: To make this soup vegan, simply substitute the chicken stock with vegetable stock. The bacon garnish can be omitted or replaced with crispy toasted breadcrumbs or roasted nuts.

Serving & Storage Suggestions

Serve this soup hot, garnished with bacon, chives, or reserved arugula. A dollop of crème fraîche or a swirl of olive oil adds a touch of elegance. It pairs perfectly with warm, crusty bread for dipping.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze the soup in individual portions for up to 2-3 months. Reheat gently on the stovetop or in the microwave until heated through.
