Lemon Asparagus on Mushroom Gravy and Kumara (Sweet Potato) Mash

A Nourishing, Flavourful Feast

This vibrant, plant-based dish celebrates the best of seasonal produce and wholesome ingredients, offering layers of flavour and nutrition in every bite. Crisp asparagus is gently tossed with lemon juice, vegetable stock, cracked pepper, and thyme, retaining its bright green colour and zesty freshness. Served over a luscious, oil-free mushroom gravy—rich with the umami of brown mushrooms, onion, garlic, soy sauce, and fresh thyme—each spoonful bursts with earthy and savoury notes.

The kumara (sweet potato) mash brings natural sweetness and a creamy texture to the plate, blending steamed orange kumara with vegetable stock, a hint of plant milk, garlic powder, and fresh parsley. Hummus adds a boost of plant-based protein, healthy fats, and flavour, making this mash both velvety and nourishing.

Health Benefits:

  • Asparagus is low in calories and high in fibre, vitamins A, C, E, and K, and the antioxidant glutathione, which supports immune health and detoxification. The lemon juice not only infuses the asparagus with a tangy flavour but also adds vitamin C for enhanced iron absorption.
  • Mushrooms are prized for their unique blend of vitamins, minerals, and antioxidants, including selenium and B vitamins, supporting immune health and energy metabolism. Cooking them in vegetable stock and soy sauce, without oil, helps keep this gravy lower in fat and sodium, especially with reduced-sodium options.
  • Sweet potato (kumara) is rich in beta-carotene (vitamin A), vitamin C, potassium, and dietary fibre, supporting eye health, digestion, and heart health. The addition of hummus introduces plant-based protein, healthy fats, and a creamy consistency that eliminates the need for dairy.
  • Garlic and fresh herbs contribute additional antioxidants and anti-inflammatory properties, enhancing both the taste and nutritive value of the dish.

With no added oils and plenty of plant-based ingredients, this meal is not only delicious and satisfying but also kind to your heart and waistline. Enjoy a comforting, beautifully balanced plate that delivers comfort and wellness in equal measure.

Normally you might find me behind the coding of our sites but over the years I have become much more concerned about what has been happening in the kitchen as well - families do that for all of us don't they? Background experience is in Account Management and Web Development but as my passion has grown for WFPB so has my desire to speak out.
