Dehydrator Cream of Broccoli Soup: A Taste of Sunshine in Every Bowl

The aroma still takes me back. My grandmother’s pantry, usually filled with the comforting scents of yeast bread and simmering sauces, held another secret: the earthy, concentrated fragrance of dehydrated vegetables. As a child, I was fascinated by these seemingly shriveled bits of garden bounty. They held the promise of summer’s abundance, preserved for the colder months. I remember her proudly rehydrating them to make a simple cream of broccoli soup that tasted impossibly fresh, even in the dead of winter. It was a dish that turned humble ingredients into something truly special, and it sparked my own lifelong love affair with the magic of dehydration.

• Total Time: 11 hours 25 minutes
• Servings: 4
• Yield: Approximately 6 cups
• Dietary Type: Vegetarian (can be made vegan with substitutions)

Ingredients

• 1 cup dried broccoli pieces
• ¼ cup dried mushroom
• ¼ cup dried shredded carrot
• 1 tablespoon dried celery powder
• 1 tablespoon dried onion pieces
• 1 teaspoon dried bell pepper pieces
• 1 teaspoon chopped garlic
• 1 teaspoon crushed dried chives

• 2 cups chicken stock (vegetable stock for vegan)
• 2 cups hot water
• ½ cup milk (plant-based milk for vegan)
• ½ cup heavy cream (plant-based cream alternative for vegan)
• 1 tablespoon all-purpose flour (gluten-free flour blend for gluten-free)
• 1 tablespoon dry sherry (optional)
• Salt and pepper to taste

Equipment Needed

• Dehydrator
• Soup kettle or large pot
• Small bowl
• Whisk
• (Optional) Immersion blender or regular blender

Instructions

1. Dehydrate the Broccoli: Start by preparing your fresh broccoli. To ensure a clean product, soak the whole head for 30 minutes in a solution of 1 part salt to 4 parts water. This encourages any lurking worms to surface. Trim the broccoli head, removing any yellowing bud clusters. Cut the florets from the stems. If you wish, peel the tough outer skin from the stems using a vegetable peeler and then cut the stems crosswise into ½-inch pieces.
2. Blanch the Broccoli: Blanching helps preserve the color and nutrients. Water-boil blanch the broccoli stems for 2 to 3 minutes or steam-blanch for 3 to 5 minutes. No need to blanch the florets.
3. Dehydrate the Vegetables: Dry the florets and stems separately on dehydrator trays. Broccoli leaves can also be dried, pulverized, and used as a flavoring agent, much like celery powder. Dry for 8 to 10 hours in a dehydrator until brittle.
4. Rehydrate the Vegetables: In a soup kettle or large pot, combine the dried broccoli, dried mushroom, dried shredded carrot, dried celery powder, dried onion, dried bell pepper, chopped garlic, crushed dried chives, and dried thyme with the chicken stock (or vegetable stock) and hot water. Let this mixture sit for at least 1 hour to allow the dried vegetables to rehydrate fully. This step is crucial for achieving the right texture and flavor.
5. Simmer the Soup: Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat to low and simmer the soup, adding a little more water if needed to prevent it from becoming too thick, for approximately 30 minutes, or until the vegetables are tender.
6. Puree (Optional): For a smoother consistency, allow the soup to cool slightly. Use an immersion blender to puree half of the soup directly in the pot, or carefully transfer half of the soup to a regular blender and puree until smooth. Return the pureed portion to the kettle. Be cautious when blending hot liquids, as they can create pressure.
7. Create the Creamy Base: In a small bowl, whisk together the milk (or plant-based milk), heavy cream (or plant-based cream alternative), and all-purpose flour (or gluten-free flour blend) until the mixture is smooth and free of lumps. This ensures a creamy, even consistency in the finished soup. Stir in the dry sherry (if using). The sherry adds a subtle depth of flavor, but it is entirely optional.
8. Combine and Thicken: Slowly whisk the milk/cream mixture into the hot soup base. Over low heat, simmer the soup, stirring frequently to prevent sticking, for 5 to 10 minutes, or until the soup has thickened to your desired consistency. If the soup becomes too thick, add additional milk or stock to thin it out.
9. Season and Serve: Season the soup generously with salt and pepper to taste. Remember that dehydrated ingredients can sometimes require more seasoning than fresh. Serve the soup hot, garnished with fresh herbs or a swirl of cream, if desired.

Expert Tips & Tricks

• Dehydration Depth: The key to successful dehydration is ensuring the vegetables are completely dry. They should be brittle and snap easily. Any residual moisture can lead to spoilage.
• Broccoli Prep: When blanching broccoli, adding a pinch of baking soda to the water can help preserve its vibrant green color.
• Flavor Boosters: For a richer, more complex flavor, consider adding a bay leaf or a Parmesan cheese rind to the soup while it simmers. Remove them before serving.
• Vegan Variations: To make this soup vegan, be sure to use vegetable stock, plant-based milk (such as oat or almond), and plant-based cream alternatives (such as cashew cream or coconut cream). Also, omit the dry sherry, as some varieties contain animal products.
• Make-Ahead Magic: The soup base (before adding the milk and cream) can be made ahead of time and refrigerated for up to 3 days. This allows the flavors to meld even further. Simply reheat and add the milk and cream before serving.

Serving & Storage Suggestions

Serve the Dehydrator Cream of Broccoli Soup hot, garnished with a sprinkle of fresh herbs like parsley or chives, or a swirl of cream. A crusty bread, such as sourdough or baguette, is the perfect accompaniment for dipping.

Leftover soup should be stored in an airtight container in the refrigerator. It will keep for up to 3 days. You can also freeze the soup for longer storage, up to 2 months. However, be aware that the texture of the soup may change slightly after freezing and thawing. The cream may separate slightly upon reheating, but this does not affect the taste. To reheat, gently warm the soup in a saucepan over low heat, stirring occasionally. If the soup is too thick, add a little milk or stock to thin it out.

FAQs (Frequently Asked Questions)

Q: Can I use frozen broccoli instead of dried broccoli?
A: While you can use frozen broccoli, the flavor and texture will be different. Dried broccoli concentrates the flavor and gives the soup a unique depth. If using frozen, sauté it with the other aromatics before adding the stock. You’ll need about 2 cups of frozen broccoli.

Q: How long does it take to dehydrate broccoli?
A: Dehydrating broccoli typically takes 8 to 10 hours at 135°F (57°C), but this can vary depending on your dehydrator and the humidity in your environment. The broccoli should be completely dry and brittle.

Q: Can I make this soup without a dehydrator?
A: Yes, you can. Use fresh or frozen broccoli and other vegetables. Sauté the vegetables until softened before adding the stock. The flavor won’t be as intense, but it will still be delicious.

Q: What if my soup is too thin?
A: If your soup is too thin, you can thicken it by simmering it for a longer period of time to allow some of the liquid to evaporate. Alternatively, you can whisk together a tablespoon of cornstarch with two tablespoons of cold water and stir it into the soup. Simmer for a few minutes until thickened.

Q: Can I freeze this soup?
A: Yes, this soup can be frozen for up to 2 months. However, the texture of the cream may change slightly after thawing.
