Roasted Red Pepper and Cauliflower Hot or Cold Soup

An unconventional family garden-grown recipe!

Total Prep and Cook Time: 1 Hour  Serves: 6 large bowls or 12 small side dishes 

This cold soup recipe came to me through my maternal Grandmother. She is an avid gardener, hiker, cross-country skier, chef, nurse, and artist. It is tradition to get original. Heirloom comfort recipes handed down in families. My Grandmother has always thought outside the box; she was the first woman in our family to graduate from college and has 6 children.

She helped me be a more confident chef, harness my inner artist through my culinary abilities, and express and show my love through cuisine. She cultivated my confidence to use rare, versatile, fresh, and innovative cuisine from around the globe and make it my own.

This recipe originated from the many summer river trips we take as a family here in Colorado. This soup is an absolute necessity for long trips. My grandma always said, “There’s nothing like being out in the hot sun baking on the river all day and then having a cool, refreshing, vivacious, and flavorful soup,” it satisfies her thirst and her appetite. It is easy to store, tastes great hot or cold, and doesn’t take up much room in your cooler.

1 tbsp extra virgin olive oil

Cold Soup

Method to the Soup Madness:

**No immersion blender is necessary!

Preheat the broiler to high. Arrange bell peppers with skin side up on a large baking sheet. Broil, then monitor carefully until skins are blackened (12-16 minutes; the better the sear, the easier to peel).

Remove peppers from the oven and allow them to cool. Peel over a bowl to collect juices. Set peppers and juices aside.

Next, in a large pot over medium-high heat, warm olive oil, add shallots, salt, cayenne pepper, and cook stirring until soft. This will take approximately three minutes. Add broth gradually and then the cauliflower. Bring to a boil and lower heat to a simmer.

Cover and cook 20 minutes, add peppers with juices and cook covered until cauliflower is tender, which will take about 10 minutes.

Purée in batches in a blender and add sugar, then ground pepper to taste. You can serve this soup cold or hot, garnish with a small drizzle of extra virgin olive oil, chopped chives, cilantro, and a squeeze or two of lemon juice to balance the flavors.
