Ingredients

Vegetables

  • 1 head broccoli, cut into florets (approx. 5 heaping cups, including stems)
  • 2 small-medium yellow potatoes (approx. 3 cups, Yukon Gold recommended)
  • 1 large bunch curly kale (approx. 6-7 cups, packed)
  • 1 small yellow onion, diced
  • 4 large cloves garlic, minced

Herbs and Spices

  • 1 tsp dried thyme
  • 1/2 tsp dried basil
  • 1 tsp smoked paprika

Liquids and Oils

  • 1/4 cup olive oil
  • 1 liter vegetable broth (low sodium, if desired)
  • 1/2 a lemon, juice only

Cheese and Seasoning

  • 1 cup freshly grated parmesan cheese (Parmigiano-Reggiano recommended)
  • Salt and pepper, to taste

Instructions

  1. Heat olive oil: In a large pot or dutch oven (approximately 5 liters), heat 1/4 cup olive oil over medium-high heat until shimmering.
  2. Sauté aromatics and vegetables: Add minced garlic, diced onion, broccoli florets, diced potatoes, dried thyme, dried basil, and smoked paprika to the pot. Cook for 7 minutes, stirring frequently, until the vegetables begin to soften and the garlic and onion are fragrant.
  3. Add kale: Stir in the curly kale and cook for about 2 minutes until it wilts and reduces in volume.
  4. Add liquids and seasoning: Pour in 1 liter vegetable broth and the juice of half a lemon. Add grated parmesan cheese along with salt and pepper to taste. Stir well to combine all ingredients.
  5. Simmer the soup: Bring the mixture to a boil, then reduce the heat to low and cover the pot. Let it simmer gently for 15 minutes, allowing the vegetables to become tender enough for blending.
  6. Blend the soup: Use an immersion blender directly in the pot to blend the soup until smooth. Alternatively, transfer the soup carefully to a high-speed blender in batches and blend until creamy.
  7. Adjust seasoning and serve: Taste the blended soup and add additional salt and pepper if needed. Serve hot, enjoying the rich, creamy texture and balanced flavors.

Notes

  • For a smoother soup, ensure vegetables are cooked thoroughly before blending.
  • If using a traditional blender, blend in batches to avoid spills and ensure even blending.
  • Low sodium vegetable broth helps control saltiness; adjust seasoning after blending.
  • Parmesan cheese adds savory depth; use Parmigiano-Reggiano for best flavor.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • Reheat gently on stovetop or microwave before serving.
