This is a blended vegetable soup built from fennel, carrots, onion, garlic, and ginger — cooked in one pot and pureed smooth. It takes about an hour start to finish and comes in at 111 calories a serving. The honest reason to make it: it uses cheap, long-shelf-life vegetables and tastes like you put in more effort than you did.
What makes this version work
Two things matter here. First, the sauté step at the start — 5 to 7 minutes in olive oil before any liquid goes in — pulls sweetness out of the fennel and onion that you simply won’t get if you just boil everything together. Don’t rush it. Second, blending while the soup is still hot (rather than cooling it first) gives you a noticeably smoother result, because the starches in the carrots are still loose and easy to break down. An immersion blender works perfectly in the pot; no need to transfer to a countertop blender and deal with the mess.
Ingredient notes
- Fennel bulb: If your grocery store doesn’t carry it or the price is high, two stalks of celery plus half a teaspoon of fennel seeds (crushed) will get you close. The seeds are usually in the spice aisle for under two dollars.
- Vegetable broth: Chicken broth works just as well if that’s what you have open. The flavor difference is minor once everything is blended. Bouillon cubes dissolved in water are fine too — use the equivalent of 4 cups.
- Fresh ginger: A quarter teaspoon of ground ginger substitutes for 1 teaspoon of fresh. It’s slightly less bright but perfectly acceptable.
- Fresh parsley garnish: Skip the garnish — not worth the extra dish if you don’t already have parsley on hand.
Mistakes to avoid
- Adding broth before the vegetables soften: Pouring in liquid too early stops the sautéing and you lose the caramelized base flavor. Wait until the onion looks translucent and the fennel has wilted.
- Not cutting vegetables to a similar size: Large chunks of carrot next to small pieces of fennel means uneven cooking. Keep everything roughly 1-inch pieces so they’re all tender at the same time.
- Under-seasoning before blending: Blending dilutes your sense of how seasoned the soup is. Taste and adjust salt after blending, not before — you’ll almost always need more than you think.
- Blending a too-full pot: If using an immersion blender, tilt the pot slightly and keep the blender head submerged to avoid hot soup splashing. If the pot is very full, ladle out a cup or two first.
- Storing with the garnish on: If you’re making this ahead, leave the parsley off until serving. Parsley wilts and turns the surface of the soup an unappetizing grey-green in the fridge.
Leftovers and make-ahead
This soup keeps well in the fridge for up to 4 days in a sealed container. It also freezes cleanly — portion it into freezer bags or containers and it’ll hold for 3 months. Reheat on the stovetop over medium-low, stirring occasionally; it thickens as it sits, so add a splash of water or broth to loosen it back up. The microwave works fine too, just cover the bowl loosely and stir halfway through. You can make the full batch on a Sunday and have lunch covered for most of the week.

Frequently asked questions
Can I use baby carrots instead of large carrots?
Yes, baby carrots work fine here. Use about 20 to 24 baby carrots to approximate 4 large ones, and chop them in half so they cook at the same rate as the other vegetables.
Do I have to use an immersion blender, or can I use a regular blender?
A regular countertop blender works — just let the soup cool for 10 minutes first and fill the blender no more than halfway per batch. Hot liquid expands when blended and can force the lid off, so hold it down with a folded towel.
Is this soup thick or brothy?
After blending it’s on the thicker side, similar to a bisque. If you prefer a thinner consistency, stir in an extra half cup of broth or water after blending until it reaches the texture you want.
Can I make this soup without oil to cut the fat?
You can swap the olive oil for a few tablespoons of water or broth and sweat the vegetables over medium heat with the lid on. You’ll lose a little of the caramelized depth, but the soup will still taste good.
My fennel bulb came with the fronds attached — can I use those?
Yes, the feathery green fronds are edible and make a better garnish than parsley for this soup since they reinforce the fennel flavor. Chop them roughly and scatter on top just before serving.
