Notes
Essential Tips for Perfect Soup
- Sauté aromatics first — it releases their full flavor and prevents rawness.
- Roast vegetables for 25-30 minutes at 200°C (390°F) for richer sweetness.
- Use an immersion blender for quick, easy pureeing directly in the pot.
- Taste and adjust seasoning at the end—soup can be bland if under-seasoned.
- Add a splash of acid—lemon juice or vinegar—to brighten the flavors.
Common Mistakes and How to Fix Them
- FORGOT to sauté the aromatics? Sauté a few minutes longer or add a splash of oil to revive flavor.
- DUMPED the spices in all at once? Add them gradually, tasting to balance the warmth.
- OVER-TORCHED the garlic? Quickly add a splash of water or broth to cool the pan and prevent bitterness.
- NEEDED to thicken the soup? Simmer uncovered for a few more minutes or mash some veggies for extra body.
Fast Fixes for Common Soup Woes
- When too thick, splash in hot broth and stir vigorously.
- If bland, add a pinch of salt or a splash of vinegar.
- Splash in a dash more spice if flavor feels flat.
- Patch dull flavor with a squeeze of lemon or lime.
- Shield burnt bits by removing them before blending, then add fresh herbs for contrast.
Prep, Store, and Reheat with Ease
- Vegetables can be chopped a day ahead and stored in airtight containers in the fridge.
- Soup keeps well in the fridge for up to 3 days; freeze for up to 3 months in airtight containers.
- Flavor deepens after a day, but may need a quick reheat and seasoning adjustment.
- Reheat on the stove over medium heat, stirring occasionally, until steaming hot and fragrant.
