This velvety and elegant soup makes the perfect first course for dinner with croutons or crusty bread for added crunch.
We think Asparagus Soup and all pureed soups taste better when topped with a little crunch to contrast the otherwise smooth texture. We keep it simple in this recipe with a few croutons next to a splash of cream, but here’s a list of tasty topping ideas for you to consider too.

Adding Roasted Vegetables to Soup
When it comes to vegetables, I highly recommend that you roast those babies! Roasting always adds a unique depth of flavor and brings out a subtle sweetness. The browning process makes the flavors really pop, balancing the vibrant and bright components with the deeper caramelization.
Taking the time to first roast the asparagus and onion before cooking the soup makes all the difference, taking this, and any vegetable recipe, from good to great with only one simple additional step.
TIP: Homemade stock will elevate the flavor of any recipe it is added to. Check out how easy it is to make your own Chicken Stock.
How to Prepare Asparagus for Roasting
When preparing asparagus, it is important to remove the woody part from the base of the asparagus spear as the fibrous part can be woody and tough. You can do this in one of 2 ways:
- Cut the bottom 1-inch or so off the asparagus spears with a sharp knife.
- Break the spears by snapping off the end where the asparagus naturally breaks at the woody part of the stem. Take a spear in both hands towards the base and gently bend it until it breaks.
RECIPE STEP BY STEP
- Roast the asparagus 8-10 minutes; coarsely chop.
- Grill or pan-sear the onions until soft and lightly charred, 8-10 minutes, while the asparagus is roasting.
- Simmer the chopped asparagus, onions, broth, thyme, and garlic 15 minutes.
- Blend soup with blender, immersion blender, or food processor.
- Return soup puree to the pan, add lemon zest, cream, salt, and pepper; simmer for 5 minutes.
TIP: For a perfectly smooth texture, allow the blender to run for 1-2 minutes.
An Easy Make Ahead Meal
Prepping and freezing meals ahead is a cooking method I teach in my Monthly Cooking Online Course. Batch cooking this tasty asparagus soup is a great way of extending the relatively short spring growing season.
As with most soups, this cream of asparagus soup is a great make-ahead dish. Once cooked and blended, cool the soup and store it in an airtight container in the refrigerator for up to 3 days, or freeze it.
It is a welcome meal on a rainy day, prepped and ready when a warming bowl of soup is just the comfort you need.
TIP: To freeze asparagus soup, cool completely, pour into freezer-safe bags, and freeze for up to 3 months. If the soup is too thick after defrosting, add a couple of tablespoons of water, stock, or cream until you reach desired texture.
