Wholesale Portobello Mushrooms in London

Heritage & Cultivation

Portobello mushrooms (Agaricus bisporus) are the fully grown form of Button and Cup mushrooms, first popularised in Europe in the late 20th century as chefs and consumers embraced their robust texture and flavour.

Rushton’s sources Portobello mushrooms from specialist British growers, primarily in regions like Herefordshire and Yorkshire. Cultivated in temperature- and humidity-controlled environments, our Portobellos are harvested at their peak to ensure wide, meaty caps with consistent quality. Supplementary supply from Dutch and Polish growers ensures year-round availability at scale.

Nutritional Profile

Portobello mushrooms are a nutrient-rich option for chefs crafting health-conscious menus:

• Excellent source of B vitamins (niacin, riboflavin, pantothenic acid)

• Provide potassium, selenium, and copper, supporting overall wellness

• Naturally low in fat and calories while high in dietary fibre

• Rich in umami compounds, enhancing savoury dishes

• Suitable for vegan, vegetarian, and gluten-free diets

When are Portobello Mushrooms in Season?

Portobellos are available throughout the year, thanks to controlled indoor cultivation:

• UK Production (Year-round): Consistent supply from British growers, with peak quality in cooler months.

• European Supply: Netherlands and Poland provide additional volumes to maintain price stability and availability during high demand.

Every mushroom is inspected to ensure firm, open caps with deep colour and reliable yield.

Chef’s Corner

• Stuffed and baked with cheese, herbs, or grains for centre-of-plate dishes

• Sliced and roasted as a robust garnish or side dish

• Marinated and seared, mimicking steaks in plant-forward menus

• Chopped into sauces and ragus for deep umami richness

• Used as a low-carb alternative to bread or buns in innovative plating

Complementary Ingredients

• Garlic, rosemary, and thyme for classic Mediterranean depth
