Yield
Serves 6 generous bowls
Difficulty Level
Medium – perfect for home cooks ready to elevate their vegan culinary repertoire
Ingredients
- 3 lbs yellow onions, thinly sliced
- 2 tablespoons olive oil
- 2 tablespoons vegan butter
- 4 garlic cloves, minced
- 1 teaspoon thyme, dried or fresh
- 1 bay leaf
- 1/2 cup dry white wine (optional but recommended)
- 8 cups vegetable broth
- 1 tablespoon balsamic vinegar
- Salt and freshly ground black pepper, to taste
- For the Cashew Cheese:
- 1 1/2 cups raw cashews, soaked at least 4 hours
- 1/4 cup nutritional yeast
- 2 tablespoons lemon juice
- 1/4 cup water (adjust for desired consistency)
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon white miso paste (optional)
- Salt to taste
- For Garnish:
- Fresh thyme sprigs
- Toasted baguette slices or gluten-free bread
Instructions
- Caramelize the onions. In a large heavy-bottomed pot,heat the olive oil and vegan butter over medium-low heat. Add the sliced onions and a pinch of salt. Stir frequently, allowing the onions to soften and turn golden brown over the next 40-50 minutes. Patience is key-stir every few minutes to prevent burning and encourage even caramelization. The onions should look deep amber and glossy.
- Add garlic, thyme, and bay leaf. Once caramelized, stir in the minced garlic, thyme, and bay leaf. Cook for 2 minutes until fragrant, but don’t let the garlic brown.
- Deglaze with white wine. Pour in the white wine to deglaze the pan, scraping up all the browned bits from the bottom with a wooden spoon. Let the alcohol cook off for about 5 minutes on medium heat.
- Add vegetable broth and balsamic vinegar. Lower the heat and pour in the vegetable broth and balsamic vinegar. Season lightly with salt and pepper. simmer gently for 20 minutes to marry the flavors and slightly reduce the liquid.
- Prepare the cashew cheese. Drain and rinse the soaked cashews. Combine them in a high-speed blender with nutritional yeast, lemon juice, water, garlic powder, onion powder, miso paste (if using), and salt. Blend until ultra-smooth and creamy. adjust water for desired texture-it should be thick but pourable.
- Serve. Ladle the soup into oven-safe bowls. Swirl a generous dollop or spoonful of cashew cheese onto each bowl. Optionally, place toasted baguette slices over the top for an authentic presentation. If you want the cheese warm and slightly melted, broil the bowls for 2-3 minutes-watch carefully to prevent burning.
- Garnish and enjoy. Finish each bowl with fresh thyme sprigs and an extra crack of black pepper. Serve immediately and savor the harmony between sweet caramelized onions and creamy cashew cheese.
Tips for Success
- Onion variety matters: Yellow onions offer ideal sweetness and caramelize beautifully. Avoid red onions as their sharpness is less suited here.
- Slow and steady wins: Patience during caramelization is essential. Rushing leads to bitterness or burning.
- Cashew cheese consistency: For a spreadable version, add less water. For a drizzle or soup swirl, thin it out slightly.
- Make-ahead magic: Caramelized onions keep well refrigerated up to 5 days, making this dish grate for busy weeknights.
- Adjust seasoning last: Since cashew cheese brings saltiness and tang, taste the soup before adding too much salt.
- Broth quality: Use a rich, flavorful vegetable broth-homemade or store-bought-to elevate the soup base.
