Celery Soup with Carrot, Parsley, and Red Pepper is a smooth or chunky vegetable soup built from celery, carrots, red pepper, onion, and broth. Add potato for a thicker body and finish with parsley and a little milk or cream if you like.
Why You’ll Love This Recipe
Sweating the onion, bell pepper, and carrots before adding celery builds a mild savory base. Blend the vegetables smooth or leave some texture, then stir in milk or cream gently at the end.
Tips for the Best Results
- Cut the vegetables into even pieces so they soften at a similar pace.
- Broth can vary in saltiness, so season lightly at first and adjust after blending.
- Add the optional potato for a thicker soup, or leave it out for a lighter broth-based bowl.
Serving and Storage
Finish each bowl with parsley and a squeeze of lemon; serve toast or crackers alongside.
Ingredient and Prep Notes
Cut the onion, bell pepper, carrots, celery, and potato into small pieces so they soften at a similar pace. Celery strings can be noticeable in a smooth soup, so peel the outside ribs if they are very mature. Sauté the vegetables until glossy and fragrant before adding broth.
Key Cooking Cues
Simmer gently until the carrots, celery, and potato are fork-tender. The potato is optional but adds body without needing much cream. Add broth in stages; the vegetables release moisture as they cook, and you can always thin the soup after blending.
Variations and Serving Ideas
Blend with an immersion blender for convenience or use a countertop blender in batches, venting steam safely. Blend fully smooth for a silky soup or leave some texture. Stir in milk or cream after blending and warm gently; avoid a hard boil once dairy is added.
Make-Ahead Guidance
Fresh parsley is best stirred in near the end or scattered over each bowl. For extra brightness, add a squeeze of lemon. If you want a deeper savory flavor, use a well-seasoned broth, then adjust salt only after blending because flavors concentrate as the soup reduces.
Storage and Reheating
Serve with toast, crackers, or a simple sandwich. Cool leftovers promptly and refrigerate for up to four days. Reheat slowly, stirring often; add broth if the soup thickens. Freeze without cream if possible, then blend or stir well after thawing and add dairy when reheating.
