Why We Love It

There’s nothing quite like cozying up with a big bowl of warm, comforting soup–especially on a cold day or when you’re feeling a little under the weather.

My family always enjoys when I make homemade soup, but I went out on a bit of a limb when I made this delicious Cream of Roasted Asparagus Soup. I am an extreme asparagus lover, and can’t get enough of it. I’m always ready to devour a bowl of Asparagus Tomato Salad.

But the rest of the family?–not so much.

I’m always looking for new ways to enjoy asparagus (and to get my family to eat it too), so when I found this tasty soup recipe tucked away in my Nana’s recipe box, I just had to give it a try.

When preparing this soup, the asparagus is first roasted in the oven with red and green onions, which creates such a hearty flavor. The vegetables then get puréed in a food processor along with some chicken broth for a fantastic, smooth texture. Some added seasonings, milk and fresh dill (one of my favorite herbs of all time) give it a wonderful taste and charm.

And guess what? Just like other meals I’ve made (Chow Mein Beefy Rice Casserole–which everyone loved, despite having reservations about new veggies), this Cream of Roasted Asparagus Soup was an instant hit! Everyone raved about the smooth, creamy texture and flavor–especially when we added a little sour cream, extra dill and green onions on top. And I was thrilled that my family was enjoying asparagus in a new way.

With this tasty Cream of Roasted Asparagus Soup recipe under my belt, I now have license to buy asparagus in larger quantities AND more frequently–especially when I promise to serve this soup alongside my legendary Ham and Swiss Cheese Sliders!

I consider that a major win.

Why You’ll Love It

Vitamin and nutrient-rich: Asparagus is loaded with potassium, which is great for your heart. Green onions offer some additional vitamin C.

Versatile: This soup can be enjoyed as a main meal or as a side. It pairs well with grilled cheese, sliders and BLTs.

Uses a blender: The hard chopping, dicing and blending are done for you in a blender or food processor. This soup is a great excuse to buy a Vitamix!

You control the creaminess: You may choose to add sour cream to the soup before serving for added thickness, tang and cream.

Description

This is not your ordinary cream of asparagus soup. The secret to its excellent flavor profile comes from roasting.

The asparagus and onions roast first in the oven, which creates such a hearty flavor. The vegetables then get puréed in a food processor along with some chicken broth for a fantastic, smooth texture. Some added seasonings, milk and fresh dill give it a wonderful taste and charm.

Dolloped with some sour cream, this nutritious soup is full of flavor and comfort!

Note

Use fresh asparagus of medium thickness for this recipe. Remember: the longer asparagus sits in the fridge, the less flavorful it'll be. Try to make this soup within a few days of buying the asparagus.

Fresh dill is highly preferred for this recipe.

I use whole milk for the cream portion, but reduced fat sour cream for the topping.

Some food for thought....

Expand All:
Can I freeze this?

I'm not a fan of freezing soups that have milk or cream in them. When they defrost, you often see white flecks, which I think is unappealing. I'd also be afraid that the soup would lose a lot of its flavor and be watery from all the vegetables. So, no, I don't recommend freezing this one.

Can I use canned asparagus?

I don't recommend it. It won't have the same flavor, plus you can't roast it like fresh asparagus.

I made a mess when I was processing the vegetables with the broth. What did I do wrong?

By mess, I'm thinking you mean liquid and vegetable matter spilled out. Oh no! That's happened to me before. Two things to remember: add the broth in 1/2 cup intervals and make sure you processor is large enough. If you have a small food processor, consider using a blender instead to get the job done without spillage!
