Ingredients For Rainbow Roasted Pepper Soup
Bell peppers: These colorful vegetables are the star of the dish, providing sweetness and a vibrant hue.
Olive oil: Used for roasting the peppers and sautéing the aromatics, it adds a rich flavor.
Onion: Adds a savory depth to the soup.
Garlic: Enhances the overall flavor with its aromatic qualities.
Vegetable broth: Forms the base of the soup, adding a savory liquid element.
Salt: Essential for seasoning and enhancing flavors.
Black pepper: Adds a touch of heat and complexity.

Technique Tip for This Recipe

bell peppers (red, yellow, orange, green) - Substitute with poblano peppers: Poblano peppers offer a similar texture and a slightly smoky flavor that complements the soup well.
olive oil - Substitute with avocado oil: Avocado oil has a high smoke point and a neutral flavor, making it a good alternative for roasting and sautéing.

minced garlic - Substitute with shallots: Shallots offer a subtle garlic-like flavor with a hint of sweetness, adding depth to the soup.

How to Store / Freeze This Soup
Allow the Rainbow Roasted Pepper Soup to cool completely before storing. This helps prevent condensation, which can dilute the flavor and texture of the soup.
Transfer the cooled soup into airtight containers. For convenience, consider using portion-sized containers so you can easily reheat just the amount you need.
Label each container with the date. This ensures you keep track of how long the soup has been stored.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The vegetable broth and roasted peppers will maintain their flavor and texture well within this timeframe.
For longer storage, place the containers in the freezer. The soup can be frozen for up to 3 months without significant loss of quality.
When ready to enjoy, thaw the soup in the refrigerator overnight. This gradual thawing process helps preserve the soup's texture.
Reheat the soup on the stovetop over medium heat, stirring occasionally. If the soup has thickened too much during storage, you can add a bit of vegetable broth or water to reach your desired consistency.
If you added heavy cream before freezing, be sure to stir the soup well as it reheats to ensure a smooth texture. If you prefer, you can add the cream after reheating to maintain its richness.
For an extra burst of freshness, garnish the reheated soup with freshly chopped herbs or a drizzle of olive oil just before serving.
