πŸ›’ Ingredients

  • 13.5 fl oz Vegetable broth
  • 3.4 fl oz Oat drink
  • Nutmeg and EVOO

πŸ₯£ Mushroom Cream: Dairy-Free Umami Elegance

Traditional mushroom cream soups are usually heavy due to the abundant addition of butter and heavy cream to achieve a silky texture. This smart version takes advantage of the toasted flavor of pan-seared mushrooms and uses oat drink (milk) to achieve a sweet and smooth creaminess, completely eliminating saturated fats and dairy from the dish.

πŸ„ Why it is exceptionally healthy

  • Immune Stimulant: Mushrooms are packed with beta-glucans and selenium, compounds that have been shown to improve the response of our defenses.
  • Cardiovascular Alternative: Oat drink naturally provides a creamy texture thanks to its soluble beta-glucans, which help drag cholesterol out of the body.
  • Potassium and Magnesium: An ideal cream for muscle recovery and nighttime rest due to its mineral balance and easy digestibility.

πŸ“ Step-by-Step Preparation

  1. The Aromatic Base: Clean and finely chop 1 large leek (about 5.3 oz / 150g, only the white part). In a pot, put 1 tbsp (15ml) of EVOO and sweat the leek over medium-low heat for 10 minutes so it releases all its sweetness.
  2. Toasting the Fungi (Key Step): Clean 14 oz (400g) of mushrooms (Portobello variety is better, they have more flavor) and slice them. Turn up the heat of the pot, add the mushrooms, and sautΓ© them vigorously. They must brown slightly to enhance their umami flavor before adding liquids.
  3. The Natural Thickener: Peel and snap 1 small potato (about 3.5 oz / 100g) and add it to the pot. Stir for 1 minute.
  4. Cooking: Pour in 13.5 fl oz (400ml) of vegetable broth. Bring to a boil, cover, and simmer over medium heat for about 15 minutes until the potato is very tender.
  5. The Vegan Creamy Touch: Remove from the heat. Add 3.4 fl oz (100ml) of oat drink (unsweetened), salt, plenty of black pepper, and a good pinch of nutmeg (essential in this recipe).
  6. Silk Texture: Blend the mixture with a high-power blender for 3 minutes without interruption. The result should be a frothy and very fine cream. Serve hot garnished with a few raw mushroom slices and a drizzle of oil.
