This vegetable soup is a thick, warming bowlful with a golden, lightly cloudy broth, tender chunks of carrot and potato, and a gentle herby depth that builds with every spoonful. The vegetables hold their shape without turning mushy, and the finish is clean and savoury with no heaviness.

What sets this version apart is how straightforward the method is. There is no blending required, no stock cubes that overpower, and no long list of hard-to-find ingredients. It suits a midweek lunch just as well as a casual supper starter. From start to finish, it is ready in around 45 minutes.

2 medium potatoes, peeled and cut into 2cm chunks
1 courgette, trimmed and cut into 1cm half-moons
400g tin of chopped tomatoes

How to Make Mary Berry Vegetable Soup Recipe

Warm the oil: Place a large, heavy-based saucepan over a medium heat and add the olive oil. Once the oil is shimmering, add the diced onion and celery, and cook gently for 6 to 8 minutes, stirring occasionally, until the onion is soft and translucent but not coloured.
Add the garlic: Stir in the chopped garlic and cook for a further 1 minute. Keep the heat at medium so the garlic softens without browning, as burnt garlic will leave a bitter edge in the finished soup.
Build the base: Add the carrots, parsnips, and potatoes to the pan and stir everything together so the vegetables are coated in the softened onion mixture. Cook for 2 minutes, stirring once or twice, to begin drawing out their natural sweetness.
Pour in the stock and tomatoes: Add the hot vegetable stock, the tin of chopped tomatoes, dried thyme, and bay leaf. Stir well, then bring the pan to a steady simmer over a medium-high heat. Using hot stock speeds up the time to simmering and prevents the vegetables from sitting in cold liquid.
Simmer until tender: Reduce the heat to low, partially cover the pan with a lid, and simmer for 15 minutes. After 15 minutes, add the courgette and continue to cook uncovered for a further 8 to 10 minutes, until all the vegetables are just tender when pierced with the tip of a knife.
Taste and season: Remove the bay leaf and discard it. Taste the soup and adjust with salt and freshly ground black pepper. Stir in a small squeeze of lemon juice to lift the flavours and brighten the broth.
Finish and serve: Ladle the soup into warmed bowls and scatter over the chopped flat-leaf parsley just before serving.

Tips for the Best Mary Berry Vegetable Soup

Why does my vegetable soup taste bland even after seasoning?

The most common cause is under-softened onions at the start. If the onion and celery are not properly cooked down before the stock goes in, the soup will lack that sweet, rounded base. Give them the full 6 to 8 minutes over a medium heat before adding anything else.

Why are my vegetables falling apart and going mushy?

Cutting the vegetables too small and simmering too long are usually to blame. Aim for the chunk sizes given in the ingredient list, and test with a knife at the earliest suggested time rather than leaving the pan unattended.

Why does my soup look grey rather than golden and vibrant?

This often happens when the tomatoes are stirred in too early and the soup is cooked at too high a temperature. Keep the heat at a gentle simmer and add the courgette only in the final 10 minutes, as it discolours quickly at a rolling boil.

Why is there a bitter undertone in the finished soup?

Garlic that has caught in a too-hot pan is the most likely culprit. Keep the heat at medium when cooking the garlic, and if it starts to smell sharp rather than sweet, take the pan off the heat for 30 seconds before continuing.

Why is my soup too thin even though I followed the recipe?

Different potato varieties release different amounts of starch. If the soup is thinner than you would like, simply mash a ladleful of the cooked potato directly in the bowl and stir it back into the pot. This thickens the broth naturally without changing the flavour.

Serving Suggestions

Serve with thick slices of crusty white bread or a warm wholemeal roll for a satisfying lunch.
Spoon into deep bowls and finish with a swirl of good-quality extra virgin olive oil and a crack of black pepper for a more polished presentation.
Pair with a wedge of strong mature Cheddar on the side for a ploughman-style supper.
Top each bowl with a small spoonful of crème fraîche and a pinch of smoked paprika for a richer, slightly smoky finish.
Serve alongside a simple green salad dressed in lemon and olive oil to round out a light evening meal.

Storage

Room temperature

Leave the soup to cool fully, then transfer to an airtight container and keep at room temperature for no longer than 2 hours before refrigerating.

Refrigerator

Store the cooled soup in a sealed airtight container in the fridge for up to 4 days. Reheat gently in a saucepan over a low to medium heat, stirring occasionally, and bring to room temperature for 10 minutes before reheating for the most even result.

Freezing

Ladle the completely cooled soup into freezer-safe containers or resealable bags, leaving a 2cm gap at the top to allow for expansion, and freeze for up to 3 months. Defrost overnight in the fridge and reheat thoroughly in a saucepan until piping hot throughout before serving.

FAQs

Can I use frozen vegetables instead of fresh in this vegetable soup?

Yes, frozen vegetables work well here. Add them straight from frozen and reduce the initial simmering time by around 3 to 4 minutes, as frozen vegetables cook through faster than fresh. The texture will be slightly softer but the flavour will be just as good.

Can I make this Mary Berry vegetable soup ahead of time?

This soup is an excellent make-ahead dish. The flavour actually deepens after a few hours as the vegetables continue to absorb the broth. Make it up to 2 days ahead, store it in the fridge, and reheat gently before serving.

Can I add pulses or beans to make this soup more filling?

A drained 400g tin of cannellini beans or butter beans works well. Add them at the same point as the courgette so they warm through without breaking down. They add a creamy texture and boost the protein content noticeably.

Can I blend this soup to make it smooth?

This recipe is designed as a chunky broth-style soup, but blending it partially with a stick blender after cooking gives a thicker, creamier consistency while keeping some texture. Blend roughly half the soup and stir the blended portion back into the chunky half for a good balance.

Is this vegetable soup suitable for a vegan diet?

Yes, as written this soup is entirely plant-based, provided the vegetable stock used is vegan-friendly. Always check the label on shop-bought stock, as some varieties contain butter or milk powder. Homemade vegetable stock is a straightforward alternative.
