Creamy Asparagus Potato Soup
This Asparagus Potato Soup is my go-to when the weather starts warming up, and fresh asparagus hits the market. There's no cream in this asparagus soup recipe. Instead, blended potatoes do all the heavy lifting, giving you a naturally creamy spring asparagus soup that's light, bright, and full of flavor. A hint of tarragon and a squeeze of lemon at the end make it taste like a lot more effort than it actually is.

Asparagus has one of the shortest seasons of any vegetable - roughly April through June - and I try to make the most of every bunch I can get my hands on!
This asparagus and potato soup is one of the recipes I come back to every single spring. It comes together in one pot in about 35 minutes, and I've gotten into the habit of making a big batch on Sunday so I have something I actually want to eat throughout the week.
What makes this one a little different is the tarragon. It's a classic French pairing with asparagus for good reason bring a subtle hint of anise that's soft enough that you won't notice it as a distinct flavor, but it lifts the whole pot and keeps the soup from tasting flat. Combined with the leek base (sweeter and more mellow than a standard onion) and the lemon finish, it's a soup that tastes like spring should taste.
If you grabbed one too many bunches at the farmers' market and need to use them up, this is exactly the recipe for that. For more ways to cook with spring produce, try my spring minestrone and spring pea soup next.
Why You Will Love This Recipe
- No Cream, No Problem. Blended potatoes give this soup a silky, velvety texture without a drop of dairy. It's rich and satisfying in a way that doesn't weigh you down.
- A Flavor Combination That Actually Works. French-inspired tarragon has a soft, anise-like quality that pairs beautifully with asparagus, and it's subtle enough that you won't place it, but you'll notice something is different. A bright squeeze of lemon at the end ties it all together.
- Built for Spring, Ready in 35 Minutes. Fresh asparagus has a short season (roughly April through June) and this recipe is designed to make the most of it in just one pot, with simple ingredients and minimal fuss.
- Packed with Good Stuff. Asparagus is one of spring's most nutritious vegetables - a solid source of folate, vitamin K, and fiber. This soup is a genuinely easy way to get a lot of it into one bowl.
- Made for Meal Prep. This soup holds beautifully in the fridge for up to 4 days and actually tastes better the next day as the flavors settle in.
Ingredients + Substitutions
- Leeks: These add a sweet, onion-like flavor to the soup. Be sure to wash them well, leeks often hide grit between layers. Use only the white and light green parts. You can use any leftover leeks to make a batch of potato leek soup next!
- Potato: A starchy potato, like Yukon Gold or Russet, adds body and creaminess without requiring actual cream. I don't recommend using red potatoes as they won't be as creamy.
- Asparagus: Look for bright green stalks with firm, tightly closed tips and avoid anything limp or with tips that are starting to open or turn brown. To trim the woody ends, hold each spear at both ends and bend gently; it will naturally snap right where the tough part begins. For this soup, thinner stalks tend to be more tender, but any size works since everything gets blended. Reserve a few tips for garnish before you chop the rest!
- Vegetable or Chicken Stock: Use a good-quality low-sodium stock to control salt levels. Vegetable stock keeps this recipe vegetarian, but rotisserie chicken stock adds extra savory depth.
- Dried Tarragon: Tarragon is a classic French pairing with asparagus. Its soft, anise-like flavor is subtle enough that it won't read as licorice, but it adds a depth that makes the soup taste like more than just blended vegetables. To use fresh rather than dried, swap it out with 1 tablespoon. I believe it's worth seeking out rather than defaulting to a substitute, but if you don't have it, fresh dill is the closest swap; thyme works too but gives the soup a more earthy, savory direction.

Asparagus Potato Soup Variations
- Make it Vegan: To make this asparagus soup completely vegan, use vegetable stock and skip the optional Greek yogurt or crème fraîche for serving. You can top it with a dollop of coconut yogurt for creaminess if desired or even stir in some canned coconut milk.
- Add Protein: For a heartier soup, add cooked chicken or turkey to the pot. Shredded rotisserie chicken works great, or you could sauté diced chicken breast and add it toward the end of the cooking process. To keep the soup vegetarian, swap out some of the potatoes for white beans. This boosts the protein a bit and the white beans blend up nice and creamy.
- Spice it Up: If you like a little heat, add a pinch of red pepper flakes or a chopped fresh chili pepper to the soup while cooking the leeks. It will give the soup a zesty kick without overpowering the fresh asparagus flavor.
- Make it Chunky: Skip the blending or only partially blend (half or a third) for a more rustic, textured soup. I use this same method in this creamy potato soup without dairy!
- Garnish with Roasted Asparagus Tips: Instead of blanching the reserved asparagus tips, try roasting them. Toss the tips with a drizzle of olive oil and a pinch of salt, spread them on a small baking sheet, and roast at 425°F for 8-10 minutes until the edges are just starting to crisp. They come out with a slightly deeper, nuttier flavor than blanched tips and add a little texture contrast on top of the smooth soup.
How to Make Asparagus Potato Soup
.
Making this creamy asparagus soup with potato is simple, with just a few fresh ingredients and easy steps, you'll have a light, flavorful soup ready in no time. To get started, trim the asparagus and cut into 1-inch pieces, setting a handful of tips aside for garnish.
Step 1: Sauté the Leeks. Heat olive oil in a large soup pot over medium heat. Add the chopped leeks and cook for 5-6 minutes until they're soft and aromatic, stirring occasionally so they don't brown.
Step 2: Add Potatoes and Stock. Stir in the diced potatoes and pour in the stock. Let everything simmer for about 15-20 minutes, until the potatoes are nearly fork-tender.
Step 3: Add the Asparagus. Add the rest of the chopped asparagus to the soup pot. Cook until you can easily pierce the asparagus with a fork while it still holds its shape; 3-5 minutes is usually enough
Step 4: Blanch the Asparagus Tips. While the soup cooks, blanch the reserved asparagus tips in a small pot of boiling water for 1-2 minutes, then transfer them to an ice water bath. This keeps them crisp and vibrant for garnish later.
Step 5: Blend the Soup. Carefully transfer the soup to a blender in batches (or use an immersion blender) and blend until smooth. Make sure to fill the blender no more than halfway, leave the lid slightly vented, and cover with a folded towel.
Step 6: Season and Serve. Return the blended soup to the pot. Stir in the lemon juice, salt, white pepper, and dried tarragon. Taste and adjust the seasonings as needed. Serve warm, topped with the asparagus tips and a sprinkle of lemon zest if desired. Pair your asparagus soup with potato, with a brie cheese grilled cheese for a full meal.
Lyn's Top Tips
- Use Fresh Asparagus. For the best flavor and color, fresh is the way to go. Look for bright green stalks with firm, tightly closed tips. Limp or woody asparagus won't blend as smoothly and the flavor won't be as vibrant.
- Don't Overcook the Asparagus. Three to five minutes of simmering is all it needs before blending. Pull it while it's still bright green. Overcooked asparagus turns the soup an army-green color and loses that fresh spring flavor you're going for.
- If Your Soup Turns Out Stringy. This happens sometimes with older or very thick stalks. Blend as thoroughly as possible and if threads are still showing up, pour the soup through a fine mesh sieve. It takes an extra minute and completely fixes it.
- Adjust Seasoning at the End. Always taste after blending before you decide you're done. Blending changes the flavor and it often needs a little more salt, an extra squeeze of lemon, or just another pinch of tarragon to come alive.
- Immersion Blender vs. Regular Blender. Either works, but an immersion blender lets you blend right in the pot with less cleanup. If you're using a regular blender, work in batches and fill it no more than halfway. Remember hot liquid expands and the lid can blow off. Hold it down with a folded kitchen towel, just in case.
- Storage: Store leftovers in an airtight container for up to 4 days or freeze it for up to 2 months. Note that the texture may separate slightly after thawing. Just give it a quick blend or a good stir while reheating and it comes right back together. Warm on the stovetop over medium heat, stirring occasionally. If it's thickened up in the fridge, thin it with a splash of broth or water until it's back to the consistency you like.
How to Make Asparagus Potato Soup in the Instant Pot or Slow Cooker
- Instant Pot: To make this creamy asparagus soup in the Instant Pot, start by setting it to "Sauté" mode and heating the olive oil. Add the leeks and cook until softened, about 5-6 minutes. Then, add the diced potatoes, asparagus, and vegetable stock, close the lid, and set the Instant Pot to cook on high pressure for 8 minutes. After the cooking time is up, carefully quick-release the pressure. Blend and season the soup as directed in the recipe card.
- Slow Cooker: For the slow cooker method, begin by sautéing the leeks in olive oil for 5-6 minutes until softened, then transfer them to the slow cooker. Add the diced potatoes, vegetable stock, and tarragon. Cook on low for 2-3 hours or high for 1-2 hours until the potatoes are tender. Once done, add the asparagus pieces and cook for an additional 30 minutes until they soften. Blend the soup with an immersion blender or transfer it to a blender in batches. Stir in the lemon juice, salt, pepper, and tarragon, and top with the reserved asparagus tips before serving.

Soup-er Toppings & Serving Suggestions
This creamy asparagus soup is perfect for a light and refreshing lunch or a cozy dinner on a weeknight. Its simple yet vibrant flavors make it a great choice for spring gatherings or as a starter for Easter or Mother's Day meals.
- Top with a swirl of Greek yogurt and a little lemon zest! This is how I always finish this soup. I find the tang cuts through the richness of the potato, and the cool creaminess against the warm soup is really lovely. Add lemon wedges on the side to let everyone dial up the brightness at the table.
- Pair it with a light salad like this avocado citrus salad for a meal packed with flavor!
- If you're looking for something heartier, serve it with a chicken club sandwich to round out the meal.
- For a seasonal pairing, this soup pairs beautifully with a simple egg dish like a frittata or a slice of quiche. The mild, herby flavors complement eggs really well, and it makes a complete spring lunch without much extra effort.
- Take it up a notch by adding a drizzle of balsamic glaze over the soup or top it with these tasty cornbread croutons.
Asparagus Potato Soup Recipe FAQs
While fresh asparagus is preferred for its texture and flavor, frozen asparagus can be used if needed. However, it may be a bit softer after cooking but likely won't matter tremendously since the soup is blended.
Yes! This soup actually tastes even better after sitting for a day or two, as the flavors have more time to develop. Simply store it in the refrigerator in an airtight container and reheat when ready to serve.
Yes, if you're looking to cut carbs or want a lighter version, you can omit the potatoes. The soup will be slightly thinner but still delicious. You could also substitute the potato with cauliflower for a similar texture.
You can, and it's actually a nice option in warmer months. The texture thickens quite a bit once chilled, so thin it out with a splash of extra broth before serving and give it a good stir. After chilling, taste the soup and re-season as needed. Cold temperatures mute flavors, so it may need a little more lemon or salt than it did warm.
