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 ideal for roasting the fennel, onion, and garlic, allowing them to caramelize and develop their natural sweetness. Make sure your oven is fully heated before proceeding to ensure even cooking.
Step 2: Prepare the Vegetables
Trim the fennel bulbs, removing any fronds and the tough stalks, then cut them into wedges. Peel and slice the onion into thin pieces. Place both the fennel and onion into a roasting tray alongside unpeeled garlic cloves. Drizzle with rapeseed or sunflower oil, and season with salt and pepper, tossing everything to ensure they’re evenly coated.
Step 3: Roast the Vegetables
Roast the seasoned fennel, onion, and garlic in the preheated oven for 25-30 minutes. You’ll know they are ready when the fennel is tender and slightly browned, while the onion becomes translucent and fragrant. Stir the mixture halfway through cooking to ensure even roasting.
Step 4: Prepare for Blending
After roasting, allow the vegetables to cool for a few minutes. Squeeze the roasted garlic out of its skins back into the tray, as this will enhance the soup’s sweetness. While this cools, boil vegetable stock in a large saucepan; this will serve as the flavorful base for your Fennel Soup with Peas & Lemon.
Step 5: Combine and Simmer
Add the roasted fennel, onion, and garlic to the bubbling vegetable stock in the saucepan. Then, toss in the frozen peas. Simmer this mixture for about 5 minutes, allowing the peas to heat and blend with the roasted flavors, creating a comforting base for your soup.
Step 6: Blend Until Smooth
Using an immersion blender, carefully blend the mixture until it’s perfectly smooth and creamy. If you prefer, you can transfer the mixture into a countertop blender, just be cautious with the hot liquid. The consistency should be silky, reflecting the luscious texture of the Creamy Roasted Fennel Soup with Peas & Lemon.
Step 7: Final Touches
Once blended, incorporate the rich coconut milk, the juice of a fresh lemon, baby spinach, and parsley into the soup. Blend again to combine all the flavors harmoniously. Taste and adjust seasoning as needed for the perfect balance of flavors.
Step 8: Serve and Enjoy
Ladle the Creamy Roasted Fennel Soup with Peas & Lemon into bowls, garnishing with additional parsley if desired. Serve hot with crusty bread or croutons for an added texture contrast, making it a lovely meal for any occasion.
