Sauté the Aromatics: In a large pot, heat 2 tablespoons olive oil over medium heat. Add 1 medium onion and sauté for 2–3 minutes until softened. Stir in 3 cloves garlic and cook for another 30 seconds until fragrant.
2 tablespoons olive oil, 1 medium onion, 3 cloves garlic
Add the Vegetables: Add celery, carrots, and red bell pepper. Stir well and cook for about 5 minutes to soften the vegetables slightly, stirring occasionally.
4 celery stalks, 3 medium carrots, 1 large red bell pepper
Simmer the Soup: Pour in the vegetable broth, add salt, black pepper, and paprika. Bring to a boil, then reduce heat to a gentle simmer. Cover and cook for 15 minutes until vegetables are tender.
4 cups vegetable broth, 1 teaspoon salt, ½ teaspoon black pepper, ½ teaspoon paprika
Blend (Optional): For a creamy celery-carrot soup, use an immersion blender directly in the pot or transfer to a blender in batches. Blend until smooth, or leave it chunky for a rustic texture.
Add Fresh Parsley & Finish: Stir in chopped parsley and lemon juice. Taste and adjust seasoning if needed.
2 tablespoons fresh parsley, 1 teaspoon lemon juice
Serve: Ladle into bowls, garnish with extra parsley, and serve hot with crusty bread or a light salad.
