Root Vegetable Zoodle Soup with Bacon and Basil Oil

This nutrient-dense root vegetable noodle soup offers a sophisticated and dairy-free twist on classic comfort food.

It is a vibrant, colourful bowl that celebrates the earthy flavours of British winter vegetables, elevated by a fragrant, homemade basil and lemon oil drizzle.

Perfect for those seeking a lighter meal that doesn't compromise on depth, this soup fits seamlessly into a healthy lifestyle or a dairy-free diet. The addition of finely sliced Brussels sprouts provides a lovely crunch, while the herb-infused chicken broth ensures every spoonful is packed with savoury goodness.

How to make Root Vegetable Zoodle Soup with Bacon and Basil Oil

Heat 1 tablespoon oil in a large pot over medium-high and cook bacon, stirring occasionally, until brown and crisp, 5–7 minutes. Transfer bacon to paper towels and let drain.

Pour off all but 2 tablespoons fat in pot and reduce heat to medium. Add onion and cook, stirring occasionally, until browned around the edges and softened, 8–10 minutes. Add garlic and cook, stirring constantly, until garlic is very fragrant, about 1 minute. Return bacon to pot and add oregano sprigs, thyme sprigs, bay leaf, and broth. Bring soup to a simmer and cook 15 minutes to allow flavours to come together.

Taste soup and season with salt and pepper; add carrot, parsnip, turnip, and brussels sprouts and cook 3 minutes (vegetables should be very al dente). Remove from heat. Discard oregano and thyme sprigs and bay leaves. Let soup sit 5 minutes (vegetables will soften a little more).

Meanwhile, combine anchovies (if using), basil, lemon zest, and remaining 4 tablespoons oil in a small bowl; season basil oil with salt and pepper.

Divide soup among bowls; drizzle with basil oil.

Soup can be made 3 days ahead. Let cool; cover and chill.
