Step‑by‑Step Instructions for Creamy Roasted Fennel Soup with Peas and Lemon
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). This temperature is ideal for roasting the fennel, turning it tender and caramelized. While your oven warms up, gather your roasting tin, as it will soon cradle the fragrant fennel and onions.
Step 2: Prepare the Vegetables
Trim the tops and bottoms of the fennel bulbs, then slice them into wedges. Peel and slice the onion into rings. In your roasting tin, combine the fennel, onion, and unpeeled garlic cloves. Drizzle with rapeseed oil and generously season with salt and pepper, ensuring everything is evenly coated to enhance the flavors in your fennel soup.
Step 3: Roast the Vegetables
Transfer the roasting tin to the preheated oven and roast the fennel, onion, and garlic for about 25-30 minutes. Keep an eye on the vegetables; they should turn golden brown and become soft. The sweet aroma filling your kitchen will let you know it’s almost time to blend your creamy roasted fennel soup!
Step 4: Incorporate the Garlic
Once roasted, remove the tin from the oven and let it cool slightly. Squeeze the softened garlic from its skins directly into the roasting tin. The garlic’s mellow flavor will beautifully enhance the soup’s taste, adding depth alongside the sweet fennel and onions.
Step 5: Boil the Vegetable Stock
In a large saucepan, bring 750 ml of vegetable stock to a gentle boil over medium heat. The bubbling stock will become the flavorful base of your soup. Once boiling, add the roasted vegetables, along with 200 g of frozen peas, and let them simmer for an additional 5 minutes.
Step 6: Blend the Soup
Using a handheld stick blender or carefully ladling the mixture into a food processor, blend the soup until smooth and creamy. Ensure there are no lumps remaining; you want a luxurious texture reminiscent of a perfect creamy fennel soup.
Step 7: Add Creaminess and Freshness
Return the blended soup to your saucepan over low heat and stir in 100 ml of coconut milk, the juice from half a lemon, and a handful each of baby spinach and fresh parsley. These vibrant additions will brighten the flavors and elevate your creamy roasted fennel soup with peas and lemon. Adjust seasoning to taste.
Step 8: Final Serve
Once everything is well combined and heated through, ladle the soup into bowls. This comforting dish is now ready to serve! Add an additional squeeze of lemon before enjoying, enhancing the fresh flavors of fennel and peas while complementing the rich creaminess.

How to Store and Freeze Fennel Soup

Creamy Roasted Fennel Soup with Peas and Lemon Recipe FAQs
How do I choose the right fennel bulbs?
Absolutely! When selecting fennel bulbs, look for ones that are firm, have no dark spots, and feel heavy for their size. Fresh fennel will have bright green fronds attached, indicating that it’s young and flavorful. Avoid any bulbs that are soft or have brown discolorations.
What’s the best way to store leftover fennel soup?
I recommend storing your leftover Creamy Roasted Fennel Soup in an airtight container in the refrigerator for up to 5 days. Ensure the soup cools to room temperature before sealing it. This helps maintain its creamy texture and fresh flavors throughout the week.
Can I freeze this soup, and how should I do it?
Very! Freezing the soup is an excellent option. Allow the soup to cool completely, then transfer it to freezer-safe containers or heavy-duty freezer bags, making sure to leave some space for expansion. It will last up to 3 months! When you’re ready to enjoy it again, simply thaw it overnight in the fridge and reheat on the stovetop, adding a splash of coconut milk if needed for creaminess.
What if my soup turns out too thick?
No worries, this can happen! If you find that your Creamy Roasted Fennel Soup is too thick after blending, simply add more vegetable stock or water, a little at a time, while mixing until you reach your desired consistency. Taste it afterwards to adjust seasoning, as additional liquid might dilute the flavor.
Is this soup suitable for pets or those with dietary restrictions?
Definitely! This vegan soup contains wholesome ingredients that are generally safe for pets, like peas and spinach, although you should always ensure no added salt or spices. However, be cautious with coconut milk if your pet is sensitive to fatty foods. For those with allergies, serve without garnishing with parsley (if a known irritant) and double-check stock labels to avoid gluten or other allergens.
How can I enhance the flavor of my soup?
The more the merrier! Try adding a pinch of cumin or coriander during roasting for a spiced twist. Also, an extra squeeze of lemon juice when you serve it can elevate the freshness and brightness of the soup, making each spoonful sing with flavor!
