🔪 How to Make Creamy Asparagus Soup

Trim off the woody ends of the asparagus. Wash, dry, and chop them into small pieces.

Heat a pot or Dutch oven to medium and add the butter. Once melted, add in the onions, asparagus, salt, and pepper.

Sauté for 3-4 minutes, then add in the garlic and sauté for another 10-15 seconds, making sure not to brown it. 

Pour in the vegetable or chicken broth and stir to combine.  Before adding the broth, I like to reserve a few of the asparagus tips for garnish.

Simmer the pot over medium-low heat for 15 minutes with an offset lid.

Pour the mixture into the bowl of a regular blender and puree. 

Tip: If you don't have a blender that can puree soup smoothly, you can try using a food processor or immersion blender instead.

Pour the pureed soup back into the pot, along with the heavy cream, lemon juice, and thyme.

Simmer for a few minutes, uncovered, until thickened to your liking.

Serve with a garnish of the reserved sautéed asparagus tips, fresh thyme, and a drizzle of the heavy cream.

💡 Tips For Buying & Storing Asparagus

The key to really good cream of asparagus soup is using healthy and fresh asparagus spears. Here's what to look for:

• Color: Look for bright green spears that are firm and straight. Avoid any that are limp, wrinkled, or discolored.
• Tight tips: Make sure the tips of the asparagus are tightly closed and not starting to flower. This indicates that they are fresh and haven't been sitting on the shelf for too long.
• Overly dry ends: Check that the cut ends of the asparagus are not dried out or moldy. All fresh spears will look slightly dry, but they should not look so dry that they are turning brown.
• Store like flowers: Until you're ready to cook it, store your asparagus in the refrigerator in a container of water with a plastic bag loosely covering the tops.
• Use quickly: Asparagus has a short shelf life, so it's best eaten within a few days of purchase.
• Trim the ends: Before cooking, trim off the woody ends of the asparagus by snapping them off at the natural breaking point or by cutting off the bottom inch or so.

How Long Does Cream of Asparagus Soup Last?

To store homemade cream of asparagus soup, cool it to room temperature, then transfer it to an airtight container. Refrigerate for up to 3-4 days.

You can also freeze it for 2-3 months. Label it with the date you made it. When ready to eat, thaw in the refrigerator overnight.

Reheat leftover, thawed soup over medium heat until warm. You may have to adjust the thickness with broth or a little more cream if it's too thick.

🍴 What Goes with Asparagus Soup?

This soup goes great with grilled chicken or steak for a hearty meal, but here are some other delicious choices:

• Crusty bread: You have to have warm crusty bread with soup, and a toasted slice of this Keto Herb Bread is a great choice if you're trying to keep the carbs low.

• Salads: Soup and salad are a classic combo. For a delicious meal, serve your soup with this Grinder Salad, this Crispy Chicken Salad or this Easy Salmon Salad.

• Quiche: For an easy meal, it's hard to beat this Quiche Loraine or this Smoked Salmon Quiche with a bowl of this cream of asparagus soup.

This mozzarella sandwich would also go perfectly on the side!

🔄 Substitutions and Additions

• Parmesan cheese: Sprinkle some freshly grated Parmesan cheese on top of each serving, or you can throw a chunk of rind over in the soup while it simmers.

• Crispy bacon: Cooked crumbled bacon adds smoky, salty flavors to the soup. You can sprinkle it on top as a garnish.  

• Potato: Add a diced and cooked russet or Yukon gold potato to make the soup thicker and heartier.   

• Leeks: Add washed, sliced, and sauteed leeks along with the onions for even more fresh flavor.

• White wine: Deglaze the pot with a splash of white wine before adding the broth for a touch of acidity.

• Sour cream or Greek yogurt: Instead of heavy cream, you can use sour cream or Greek yogurt for a tangier flavor.

• Red pepper flakes: For a bit of heat, you can add a pinch of red pepper flakes to the sautéed vegetables.

• Spinach: Blend in some fresh spinach leaves after the soup has cooked. It gives the soup extra nutrients and a fresh pop of green color 

• Crème fraiche: Add a dollop of crème fraiche on top of each bowl in place of the drizzle of heavy cream.

Is Asparagus a Low Carb Vegetable? Can you Eat Asparagus on Keto?

They are not good for eating, but you can freeze them and use them later to make vegetable stock. Or, if you live in a wooded area with wild life, deer and rabbits love them!

What Does Cream of Asparagus Soup Come From?
