Ingredients

  • 1 large yellow onion, thinly sliced
  • 1 cup raw cashews, soaked in hot water for 20 minutes
  • 1/2 cup water (or as needed for consistency)
  • 2 tablespoons nutritional yeast
  • 1 tablespoon lemon juice
  • 1 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1 teaspoon soy sauce (or tamari for gluten-free)
  • 1 tablespoon olive oil or any neutral oil
  • Salt and pepper to taste
  • Fresh chives or parsley for garnish (optional)

Equipment

  • Large skillet or frying pan
  • Food processor or high-speed blender
  • Measuring cups and spoons
  • Sharp knife and cutting board
  • Mixing bowl
  • Spatula or wooden spoon

Instructions

  1. Prepare the cashews: Soak the raw cashews in hot water for at least 20 minutes to soften. After soaking, drain and rinse them.
  2. Caramelize the onions: Heat the olive oil in a large skillet over medium heat. Add the thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions turn golden brown and caramelized, about 20-25 minutes. Be patient — this step develops the dip’s signature flavor.
  3. Blend the dip base: In a food processor or blender, combine the soaked cashews, water, nutritional yeast, lemon juice, garlic powder, smoked paprika, soy sauce, salt, and pepper. Blend until smooth and creamy, adding more water as needed to reach a thick but spreadable consistency.
  4. Mix onions with the creamy base: Add about 3/4 of the caramelized onions to the cashew mixture and pulse a few times to combine but still leave some onion texture. Stir in the remaining onions gently.
  5. Adjust seasoning: Taste the dip and adjust salt, pepper, or lemon juice as needed to balance the flavors.
  6. Chill and serve: Transfer the dip to a serving bowl and refrigerate for at least 30 minutes to let the flavors meld. Garnish with fresh chives or parsley before serving.

Tips & Variations

“Caramelizing onions is the key to the best onion dip! Take your time, and don’t rush this step.”

  • Make it spicy: Add a pinch of cayenne pepper or a dash of hot sauce to the dip for a little kick.
  • Use different onions: Try sweet onions or red onions for a milder or more colorful dip.
  • Herbal twist: Mix in fresh herbs like dill, thyme, or rosemary for a nuanced flavor profile.
  • Nut-free option: Substitute soaked sunflower seeds or silken tofu for cashews if you have a nut allergy.
  • Make it smoky: Increase the smoked paprika or add a teaspoon of liquid smoke for a deeper smoky flavor.
