Ingredients Method Notes

Ingredients
  

  • 1/2 cup uncooked quinoa rinsed
  • 4 –5 cups vegetable or mushroom broth
  • 10 oz cremini mushrooms sliced thick
  • 3 cups fresh baby spinach
  • 1 medium yellow onion diced
  • 6 whole garlic cloves peeled
  • 2 garlic cloves minced
  • 2 tbsp Extra Virgin Olive Oil
  • 1 tsp fresh thyme or rosemary
  • 1/2 tsp red chili flakes
  • 1 tbsp fresh lemon juice
  • 4 poached eggs optional garnish
  • Salt and black pepper to taste

Method
 

  1. Sauté: Heat olive oil in a pot. Sauté onions and whole garlic cloves for 5 minutes.
  2. Brown: Add mushrooms. Sear for 4 minutes without stirring, then cook until browned.
  3. Simmer: Add quinoa, minced garlic, chili flakes, and broth. Simmer covered for 15-20 minutes.
  4. Wilt: Turn off heat. Stir in spinach and herbs until wilted.
  5. Finish: Add lemon juice, salt, and pepper. Serve with a poached egg on top.

Notes

  • The Mushroom Secret: For the best flavor, allow the mushrooms to sear undisturbed in the olive oil for at least 3-4 minutes. This creates the "umami" depth essential for a meatless soup.
  • Quinoa Prep: Always rinse your quinoa in a fine-mesh sieve before cooking to remove the natural saponins, which can otherwise add a bitter aftertaste.
  • Spinach Tip: Add the spinach only after the heat is turned off. The residual heat will wilt it perfectly without losing that vibrant emerald color.
  • Storage: This soup keeps beautifully in the fridge for up to 4 days. If the quinoa absorbs too much broth overnight, simply add a splash of water or vegetable stock when reheating.
  • Vegan Option: To make this recipe strictly vegan, omit the poached egg and top with toasted pine nuts or a dollop of tahini for creaminess.
