Ingredients for amelie's spinach asparagus leek soup

Fresh herbs and seasonal vegetables create this velvety soup that tastes like a Parisian bistro in your kitchen.

Ingredient Amount Notes
Fresh Spinach 🌿 4 cups Packed, loosely chopped
Asparagus Spears 🌱 1 lb Trimmed, tough ends removed
Leeks 🧅 2 whole White and light green parts, sliced
Yellow Onion 🧅 1 whole Medium, finely diced
Garlic Cloves 🧄 3 cloves Fresh, minced
Vegetable Stock 💧 4 cups Low-sodium preferred
Heavy Cream 🥛 ½ cup Full-fat for richness
Fresh Thyme 🌿 ¼ cup Leaves only, finely chopped
Fresh Tarragon 🌿 ⅛ cup Chopped, optional but recommended
Extra-Virgin Olive Oil 🫒 ¼ cup High-quality, fruity
Salt 🧂 1 ½ tsp Diamond Crystal preferred
Black Pepper 🌶️ ½ tsp Freshly ground
Lemon Juice 🍋 1 tbsp Freshly squeezed
Chicken-Free Vegetable Broth 💧 ½ cup For garnish, optional
Crème Fraîche 🧀 ¼ cup For garnish, optional

The leeks and asparagus are the soul of this soup—fresh, vibrant, and seasonal. For leeks, focus on the white and pale green parts, slicing them thinly for even cooking. Whole Foods or local farmers markets often carry the best asparagus, especially in spring. Trim the woody ends and snap the spears—if they break cleanly, they're fresh. The spinach? Baby spinach works perfectly, but avoid anything wilted or yellowed. Fresh thyme and tarragon elevate this soup to restaurant-quality—Penzeys or a trusted local herb shop are great sources for these aromatic herbs. If you can't find tarragon, a pinch of basil or parsley will still bring brightness to the dish.

No fresh tarragon? Dried tarragon at one-third the amount works in a pinch, though fresh is ideal. Substituting vegetable stock for chicken stock is essential for a vegetarian version—Imagine or Pacific Foods brands are reliable. For a dairy-free twist, swap heavy cream for cashew cream or coconut milk, though the texture will be slightly lighter. The olive oil should be extra-virgin and fruity—none of that cheap, bitter stuff. Lemon juice is key for that final bright note, so use freshly squeezed. If you're short on time, a squeeze bottle of pre-squeezed lemon juice from Trader Joe's is a lifesaver.

This soup tastes even better the next day as flavors meld—store leftovers in the fridge for up to 5 days. For a quick lunch, reheat gently and garnish with a swirl of crème fraîche and a drizzle of vegetable broth. Freezes beautifully for up to 3 months—just thaw in the fridge overnight. To prep ahead, chop all vegetables and store them in airtight containers in the fridge for 2 days. The herbs should be added fresh right before blending for maximum aroma and flavor. Garnish with extra herbs or a sprinkle of toasted pine nuts for a Parisian touch.

Step-by-step instructions for amelie's spinach asparagus leek soup

Here's how to craft this velvety, herb-infused masterpiece—simple steps, big flavor.

1

🍳 Step 1: Sauté the Aromatic Base

Heat the 0.25 cup extra-virgin olive oil in a large pot over medium heat. Add the sliced 2 whole leeks and 1 whole yellow onion, cooking for 8-10 minutes until the leeks are tender and the onion becomes translucent. Stir occasionally to prevent browning.

Leeks can be sandy—rinse them thoroughly before slicing to remove any grit. You'll know they're ready when they soften and release their delicate, slightly sweet aroma. Add the 3 cloves minced garlic and cook for another 30 seconds until fragrant. This aromatic foundation is the soul of your soup.

2

🍳 Step 2: Add Vegetables and Stock

Increase heat to medium-high and add the 1 lb trimmed asparagus spears, cutting them into 1-inch pieces if they're thick. Cook for 3-4 minutes until they begin to soften slightly. Pour in the 4 cups vegetable stock and bring to a gentle boil.

Once boiling, reduce heat to medium-low and let it simmer for 10 minutes until the asparagus is tender but still holds its shape. The stock should be bubbling gently—this ensures even cooking without breaking down the vegetables into mush. Here's the thing—don't skip this simmering time; it's what builds the soup's depth.

3

🥘 Step 3: Blend Until Silky Smooth

Using an immersion blender (or carefully transferring to a countertop blender), purée the soup until completely smooth. I like to blend in batches if needed, but be cautious—hot liquids can splatter. The soup should have a velvety texture with no visible chunks at this stage. Taste and adjust seasoning with 1.5 tsp salt and 0.5 tsp black pepper.

Real talk: if it tastes bland at this point, don't panic—we're adding fresh herbs and cream next. The base should be flavorful but balanced, with a clean vegetable taste that lets the herbs shine. If it's too thin, simmer uncovered for 5 minutes to reduce slightly before proceeding.

4

🍳 Step 4: Finish with Herbs and Cream

Return the soup to medium heat and stir in the 0.25 cup chopped fresh thyme, 0.125 cup chopped fresh tarragon, and 1 tbsp lemon juice. Simmer for 2 minutes to let the herbs infuse. Then stir in the 0.5 cup heavy cream and 4 cups loosely chopped fresh spinach, cooking just until the spinach wilts completely.

Here's where it gets fun—the spinach should melt into the soup, creating a vibrant green color and adding a fresh, slightly bitter contrast to the creamy base. The herbs should be fragrant but not overpowering; you're aiming for a bright, herbaceous note that complements rather than dominates. If the soup looks too thick, whisk in 1-2 tablespoons of water to reach your desired consistency.

5

🍽️ Step 5: Garnish and Serve Warm

Ladle the soup into bowls and garnish with a dollop of 0.25 cup crème fraîche and a drizzle of 0.5 cup chicken-free vegetable broth (if using). The crème fraîche adds a luxurious tang that cuts through the richness of the cream, while the broth garnish brings a fresh, bright finish. Serve immediately while steaming hot—this soup is best enjoyed fresh from the pot.

Each spoonful should deliver a perfect balance of creamy, herby, and slightly tangy flavors with a vibrant green color. The texture should be velvety smooth with just enough body to coat the back of your spoon. Pair with crusty bread to soak up every last drop of that herb-infused goodness.

Pro Tips For Making Amelie'S Spinach Asparagus Leek Soup

  • CHAR THE LEEKS FIRST: I learned this the hard way—skipping the initial char on leeks and onions makes the soup taste dull. Sear them over medium-high heat until the edges of the leek whites turn golden brown (about 8-10 minutes), stirring occasionally. That caramelized flavor is what ties the whole dish together.
  • TRIM ASPARAGUS LIKE A PRO: Cut asparagus spears into 2-inch pieces, but don’t just hack at them—use a sharp knife and angle the blade slightly to avoid splintering. Save the tough bottoms for stock (if you’re ambitious) or compost them. Fresh asparagus should snap cleanly at the stem end—if it bends, it’s past its prime.
  • DON’T BOIL THE SPINACH: Add spinach to the soup after removing it from direct heat, or it’ll turn to mush. A handful at a time, stirred in until just wilted (about 30 seconds). Overcooking spinach kills its vibrant color and makes the soup taste bitter—trust me, you’ll notice the difference.
  • SALT THE WATER FOR ASPARAGUS: If blanching asparagus (which you should, to soften it without overcooking), use salted water—about 1 teaspoon per quart. It crisps the edges better and keeps the color bright. Drain immediately and shock in ice water to stop cooking; this keeps the spears tender-crisp in the soup.

Make-ahead tips for leftovers

Prep Ahead Essentials

Chop all vegetables—leeks, asparagus, and onion—and store them in airtight containers in the fridge for up to 2 days. Keep the fresh herbs (thyme, tarragon) separate until ready to use, as they lose potency when stored too long.

I like to prep everything the night before so I can focus on blending and finishing the soup the next day. 🌿

Freezer-Friendly Base

Make the soup base—everything up to blending—3 days ahead and freeze in airtight containers. Thaw overnight in the fridge before adding fresh spinach, herbs, and cream.

The flavors actually deepen over time, making it perfect for lazy weeknights. Just reheat gently on the stovetop with a splash of water if needed. ❄️

Herb Infusion Hack

For maximum flavor, add fresh herbs and spinach right before serving. Store the finished soup (without these) in the fridge for 4 days or freeze for 3 months. When reheating, stir in fresh herbs and spinach just before serving—this keeps the vibrant green color and bright aroma intact. 💫

Garnish Prep

Make your garnishes ahead of time: Whisk crème fraîche with a pinch of salt and store in a small jar. Keep the vegetable broth in a squeeze bottle for easy drizzling.

I also toast pine nuts in advance (5 minutes in a dry pan) and store them in a sealed container—they add a lovely crunch when sprinkled on top. 🌟

Reheating Like a Pro

Gently reheat soup on the stovetop over low heat—never microwave, as it can make the texture grainy. If the soup thickens too much, whisk in 1-2 tablespoons of water or stock to restore creaminess. For extra richness, stir in a splash of heavy cream while reheating. 🔥

Portion Control

Store individual portions in glass mason jars for easy grab-and-go lunches. The soup reheats beautifully in jars—just pop them in a pot of simmering water for 10 minutes or microwave for 2 minutes (covered).

The jars also make it easy to see the vibrant green layers of spinach and herbs. 💡

Frequently asked questions

1

Can I make this soup without fresh herbs?

You can substitute dried herbs, but fresh is ideal for that bright, aromatic flavor. Use 1/4 teaspoon dried thyme and 1/8 teaspoon dried tarragon (or a pinch of basil) per recipe. For best results, add dried herbs during the simmering phase and taste frequently—they infuse differently than fresh.

2

How do I adjust the soup for a dairy-free version?

Swap the heavy cream for cashew cream (blend 1 cup soaked cashews with 1 cup water) or full-fat coconut milk. The texture will be slightly lighter, but the flavor remains rich. For extra creaminess, add 1 tablespoon nutritional yeast when blending. Garnish with dairy-free alternatives like coconut yogurt.

3

Why did my soup turn out too thin?

This usually happens if the asparagus and leeks weren't cooked long enough to break down slightly. Simmer the blended soup uncovered for 5-10 minutes to reduce the liquid, or stir in 1-2 tablespoons of cornstarch mixed with water. For a richer texture, whisk in 1/4 cup additional heavy cream or cashew cream.

4

Can I use frozen spinach instead of fresh?

Yes, but thaw and drain it thoroughly first to avoid watery soup. Use 1 cup frozen spinach (about half the fresh amount) and add it with the herbs in the final step. Frozen spinach works well, but fresh gives that vibrant green color and brighter flavor. If using frozen, squeeze out excess liquid before adding.

5

What's the best way to reheat leftovers?

Always reheat gently on the stovetop over low heat—never microwave, as it can make the soup grainy. If it thickens too much, whisk in 1-2 tablespoons of water or stock. For extra richness, stir in a splash of heavy cream while reheating. Add fresh herbs and spinach just before serving for maximum flavor.
