Step‑by‑Step Instructions for Creamy Roasted Fennel Soup with Peas & Lemon
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). This temperature is perfect for roasting the fennel and onion to bring out their natural sweetness. While the oven warms up, gather your roasting dish and prepare the vegetables for an aromatic cooking experience.
Step 2: Prepare the Vegetables
Trim the fennel bulbs by cutting off the fronds and base, then slice them into wedges. Next, peel and slice the onion into thin strips. Don’t forget to also prepare the garlic cloves by leaving them unpeeled—this will add a delightful flavor once roasted.
Step 3: Combine & Season
Place the fennel wedges, sliced onion, and unpeeled garlic in a large roasting dish. Drizzle with rapeseed or sunflower oil, sprinkle with salt and pepper, and toss everything together. Make sure the vegetables are well-coated; they’ll roast beautifully, achieving that mouthwatering caramelization and flavor!
Step 4: Roast the Vegetables
Roast the combined vegetables in the preheated oven for 25-30 minutes. You’ll know they’re done when the fennel is tender and shows a lovely golden-brown color. This roasting step is crucial for creating a deep, delicious flavor in your creamy roasted fennel soup.
Step 5: Squeeze the Garlic
Once the vegetables are roasted, carefully squeeze the softened garlic from its skins and add it back into the roasting dish. The roasted garlic will enhance the soup’s creamy texture and sweetness, melding perfectly with the fennel and peas for a delightful flavor.
Step 6: Prepare the Soup Base
In a medium saucepan, bring approximately 4 cups of vegetable stock to a gentle boil over medium heat. Once boiling, add the roasted vegetables from the roasting dish along with the frozen peas. Let the mixture simmer for about 5 minutes; this will infuse the stock with the lovely flavors of the fennel soup.
Step 7: Blend the Soup
After simmering, carefully transfer the entire mixture into a blender or use an immersion blender right in the pot. Blend until you achieve a smooth, velvety texture, allowing the flavorful components of your fennel soup with peas & lemon to come together beautifully.
Step 8: Add Creaminess and Flavor
Return the blended soup to the saucepan over low heat. Stir in the coconut milk, freshly squeezed lemon juice, baby spinach, and chopped parsley. Warm gently for an additional 2-3 minutes until the spinach wilts. This adds a rich creaminess and brightness to your wonderful soup.
Step 9: Adjust Seasoning
Finally, taste your creamy roasted fennel soup and adjust the seasoning if needed, adding more salt, pepper, or lemon juice to suit your preference. This final touch ensures that every spoonful is bursting with flavor, making your soup truly irresistible!

Fennel Soup with Peas & Lemon Recipe FAQs
How to choose ripe fennel?
