Fennel Soup with Peas & Lemon Ingredients
For the Soup
- Rapeseed or Sunflower Oil – Adds richness and helps roast the vegetables; substitute with any neutral oil.

- Small Onion – Enhances the soup’s base flavor; you can interchangeably use yellow or white onion for a similar taste.
- Garlic Cloves – Roasting in their skins mellows the garlic and adds a subtle sweetness, so always opt for fresh cloves for the best flavor.
- Vegetable Stock – Serves as the soup’s base; be sure it’s vegan, and low-sodium varieties allow for better seasoning control.
- Frozen Peas – Contribute sweetness and creaminess without overpowering the fennel; fresh peas can be a delightful substitute if available.
- Coconut Milk – Adds a silky texture and subtle coconut flavor; can be replaced with any dairy-free cream if necessary.

Step‑by‑Step Instructions for Fennel Soup with Peas & Lemon
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). This ensures that your vegetables roast evenly and develop a wonderful caramelized flavor. While the oven heats up, gather your fennel bulbs, onions, and garlic cloves to prepare them for roasting.
Step 2: Prepare the Vegetables
Trim the fennel by removing the stem and tips, then cut the bulbs into wedges. Slice the onion into thin pieces, and place both in a roasting tray alongside unpeeled garlic cloves. Drizzle the vegetables with rapeseed or sunflower oil, then season generously with salt and pepper, ensuring everything is well coated.
Step 3: Roast the Vegetables
Slide the roasting tray into the preheated oven and roast for 25-30 minutes. Keep an eye on the fennel; it should become tender and lightly browned, developing a sweet aroma that fills your kitchen. Stir the vegetables halfway through to ensure they roast evenly.
Step 4: Incorporate Roasted Garlic
After roasting, take the tray out of the oven and let it cool slightly. Squeeze the roasted garlic cloves from their skins into the tray, discarding the peels. This will add a sweet, mellow flavor to your Fennel Soup with Peas & Lemon.
Step 5: Bring Stock to a Boil
In a large saucepan, add your vegetable stock and bring it to a boil over medium-high heat. Once boiling, carefully add the roasted fennel, onion, and garlic, followed by the frozen peas. Allow the mixture to simmer for about 5 minutes, letting the flavors meld beautifully.
Step 6: Blend for Creaminess
Using an immersion blender or transferring the mixture in batches to a countertop blender, blend the soup until completely smooth. Aim for a silky texture that is free of lumps, as this quality is key to the comforting nature of your creamy roasted fennel soup.
Step 7: Enhance the Flavor
Return the blended soup to the pot and stir in the coconut milk and fresh lemon juice, creating an invitingly creamy base. Toss in the baby spinach and freshly chopped parsley, blending once more until the greens are incorporated, adding vibrant color and nutrition to your soup.
Step 8: Taste and Adjust
Give your Fennel Soup with Peas & Lemon a taste. If desired, adjust the seasoning with more salt, pepper, or an extra squeeze of lemon juice for brightness. You want each spoonful to be balanced and flavorful, ensuring your guests will love every bite.
Step 9: Serve and Enjoy
Ladle the soup into warm bowls, and consider drizzling a little extra coconut milk on top for a beautiful presentation. Pair the warm soup with crusty bread for dipping, and enjoy the comforting flavors with your family or friends—this dish is sure to bring everyone together!

Fennel Soup with Peas & Lemon Recipe FAQs
How do I know if my fennel is ripe?
Absolutely! Look for fennel bulbs that are firm and heavy for their size, with no dark spots or blemishes. The outer leaves should be bright green and crisp rather than wilted. If the bulb feels soft or has dark spots all over, it’s best to avoid it.
How should I store leftovers of the soup?
Very! Store your Fennel Soup with Peas & Lemon in an airtight container in the refrigerator for up to 3 days. Ensure that the soup is completely cooled before sealing; this helps maintain its freshness. To reheat, simply warm it gently on the stovetop while stirring occasionally.
Can I freeze this soup, and how?
Certainly! This soup freezes well. To freeze, pour the cooled soup into freezer-safe containers, leaving some room at the top for expansion as it freezes. It can be stored for up to 3 months. When you’re ready to enjoy it, thaw overnight in the fridge, then reheat on the stovetop. Adding a splash of coconut milk before serving can refresh its creamy texture.
What can I do if my soup is too thick?
If your Fennel Soup with Peas & Lemon turns out too thick for your liking, don’t worry! Simply stir in more vegetable stock or a bit of water while reheating until you reach your desired consistency. You might also add a little coconut milk for an extra creamy touch.
Is this soup safe for my pets or allergies?
Yes! This vegan soup is a safe choice for most people with dietary restrictions, but be cautious if anyone has specific allergies to any ingredients like coconut or legumes. Always consult your vet before sharing homemade meals with pets, as the soup may contain ingredients that could upset their stomachs.
What should I do if I don’t have fresh lemon juice?
If you find yourself without fresh lemon juice, it’s perfectly fine to use bottled juice in a pinch!
