Instructions

creamy roasted fennel soup
1

Roast the fennel

Preheat the oven to 200°C (400°F). Toss fennel slices with 2 tbsp olive oil, salt, and pepper. Spread on a baking sheet and roast 20 minutes, turning once, until caramelized and tender.

Pro Tip: Add a pinch of fennel seed for extra depth.
2

Sauté aromatics

In a large pot, heat remaining 1 tbsp olive oil over medium heat. Add diced onion, carrots, and garlic. Cook, stirring occasionally, for 5‑6 minutes until softened and fragrant, but not browned.

Pro Tip: Deglaze with a splash of broth to lift caramelized bits.
3

Combine & simmer

Add the roasted fennel, vegetable broth, and thyme to the pot. Bring to a gentle boil, then reduce heat and simmer 10 minutes, allowing flavors to meld. Taste and adjust salt/pepper now.

Pro Tip: If the soup feels thick, add a splash more broth.
4

Blend to silk

Using an immersion blender, purée the soup until completely smooth. Alternatively, transfer in batches to a countertop blender. Return to pot, stir in heavy cream, and warm gently—do not boil.

Pro Tip: Add a squeeze of lemon juice for bright contrast.
5

Serve & garnish

Ladle soup into warmed bowls. Top each serving with torn fennel fronds, a drizzle of extra cream, and a crack of black pepper. Serve immediately with crusty bread.

Pro Tip: A few toasted pine nuts add a pleasant crunch.

Expert Tips

Tip #1: Roast Longer for Deeper Flavor

If you have extra time, extend the roasting to 25‑30 minutes. The additional caramelization intensifies the natural sweetness and adds a subtle smoky note that elevates the soup.

Tip #2: Use an Immersion Blender

An immersion blender keeps the soup in the pot, preserving heat and reducing cleanup. Blend in stages, moving the blade around to avoid splatter and achieve a uniform texture.

Tip #3: Finish with Acid

A teaspoon of fresh lemon juice or a splash of white wine vinegar brightens the final dish, balancing the richness of the cream and roasted fennel.

Storage & Variations

Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently on the stove, adding a splash of broth if needed. For a vegan version, swap cream for coconut milk and use vegetable broth with no animal products. Add a pinch of smoked paprika for a subtle smoky twist.

Frequently Asked Questions

Yes. Cool the soup completely, portion into airtight containers, and freeze for up to 2 months. Thaw overnight in the fridge, reheat gently, and stir in a splash of cream before serving.

Substitute with an equal amount of celery root and add ½ tsp of anise seed or a pinch of fennel pollen. The flavor won’t be identical but will retain a gentle licorice note.

Replace the heavy cream with ½ cup of full‑fat coconut milk or a plant‑based cream. Use a vegetable broth without added dairy flavors for a completely vegan version.
