Gluten-Free • Vegan • Vegetarian • Plant-Based • Dairy-Free • Whole-Food • High-Fibre

Introduction

This gluten-free 5-Ingredient Pea Soup is a simple, nourishing plant-based soup made with peas, potato, onion, garlic and vegetable stock, with fresh parsley and lemon adding a bright finish.

Peas provide plant-based protein and fibre, while potato naturally thickens the soup and creates a creamy texture without needing cream or dairy. Fresh garlic and onion build the savoury base, and a squeeze of lemon balances the natural sweetness of the peas.

This is a naturally vegan and vegetarian gluten-free soup when prepared with certified gluten-free vegetable stock, making it an easy choice for anyone looking for wholesome gluten-free vegan recipes made from everyday ingredients.

Benefits of All the Ingredients

Onion

Onion provides the aromatic foundation of the soup and develops a naturally sweeter, more mellow flavour as it cooks.

It provides small amounts of vitamin C, folate and potassium, alongside naturally occurring plant compounds including quercetin and organosulfur compounds.

Fresh onion is naturally gluten-free and is an easy way to develop flavour in gluten-free vegan cooking without relying on processed seasoning mixes.

Garlic

Garlic adds depth and a distinctive savoury flavour.

It belongs to the allium family and contains naturally occurring organosulfur compounds. Chopping or crushing fresh garlic initiates reactions responsible for many of its characteristic aromatic compounds.

Fresh garlic is naturally vegan and gluten-free.

Potato

Potato gives the soup body and helps produce a naturally creamy consistency without requiring flour, butter or dairy cream.

Potatoes provide potassium, vitamin C and vitamin B6, as well as carbohydrates for energy.

They also provide some fibre and are naturally gluten-free, making potatoes a useful whole-food ingredient for thickening gluten-free vegetarian and vegan soups.

Peas

Peas are the star ingredient and provide the soup's vibrant green colour and naturally sweet flavour.

Unlike many vegetables, peas provide a notable amount of plant-based protein alongside dietary fibre.

They also contribute vitamin C, vitamin K, folate, thiamine and manganese, as well as carotenoids including lutein and zeaxanthin.

Fresh and plain frozen peas are naturally gluten-free. When using packaged products for a strict gluten-free diet, check the label if cross-contact is a concern.

Vegetable Stock

Vegetable stock creates the savoury liquid base and brings the vegetables together.

Its nutritional content varies considerably depending on the vegetables and other ingredients used.

Stock is particularly important to check when preparing gluten-free soup, as some commercial stock cubes, powders and prepared broths can contain wheat or other gluten-containing ingredients.

Choose a vegetable stock specifically labelled gluten-free when preparing the recipe for someone with coeliac disease.

Fresh Parsley

Parsley provides freshness, colour and a light herbal flavour.

It contains vitamin K, vitamin C and provitamin A carotenoids, alongside naturally occurring plant compounds.

Fresh herbs are an excellent way to add flavour to whole-food, gluten-free vegan recipes without relying on additional processed sauces or seasoning blends.

Lemon Juice

Fresh lemon juice brightens the soup and helps balance the natural sweetness of the peas.

Lemon juice provides vitamin C and naturally occurring citrus flavonoids.

Adding it towards the end of preparation gives the soup a fresher flavour and complements both the peas and parsley.
