How to Make Delia Smith’s Brussels Sprout Soup
- Prepare the Brussels sprouts: Trim the ends, remove any tough outer leaves, and wash thoroughly. Measure out 350 g trimmed.
- Shred the sprouts: Blend or finely shred the Brussels sprouts for even cooking.
- Sauté aromatics: Heat the olive oil in a medium pot. Add the onion and garlic, cooking gently for 3–4 minutes until softened.
- Add shredded sprouts: Stir in the Brussels sprouts and cook for 1 minute to release their aroma.
- Simmer the soup: Pour in the vegetable stock, season with pepper, and bring to a boil. Lower the heat and simmer for 5 minutes.
- Add petit pois: Stir in the frozen peas and cook for an additional minute until just heated through.
- Blend and finish: Remove from heat. Purée the soup using a hand blender or high-speed blender until silky. Stir in the butter, adjust seasoning if needed, and serve warm.

Common Mistakes to Avoid
- Overcooking the sprouts: Keep simmering time short to preserve flavor and color.
- Skipping the shredding: Finely shredded sprouts cook evenly and blend more smoothly.
- Using poor-quality stock: A flavorful vegetable stock makes all the difference.
- Blending while too hot: Let the soup cool slightly to avoid splattering.
- Forgetting to season properly: Taste and adjust after blending for best results.
Storage and Reheating Instructions
Storage:
Cool the soup completely, then transfer to a sealed container. Refrigerate for up to 4 days.
Freezing:
Freeze in an airtight, freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating:
- Stovetop: Heat gently over medium-low, stirring often, until warmed through. Add a splash of water if it has thickened.
- Microwave: Heat in 30-second bursts, stirring between each, until hot.
