200 g celery, chopped (2 cups)
200 g green lentils (1 cup)
140 g yellow split peas, or extra lentils (3/4 cup)
1 onion, chopped
5 cloves garlic, minced
2–2.5 liters vegetable or chicken broth (8–10 cups)
2 teaspoons herbes de Provence
1 teaspoon salt (more to taste)

Add at the end:

2–3 cups (about 100–150 g) kale, stems removed and chopped

Instructions

Place the butternut squash, carrots, potatoes, celery, lentils, split peas, onion, garlic, broth, herbes de Provence, and salt into the crockpot.
Cover and cook on high for 5-6 hours or low for 7-8 hours until the vegetables and lentils are tender.
Remove about 4 cups of soup and place in a blender with the olive oil.
Pulse gently until the mixture is semi-smooth and creamy, allowing the olive oil to emulsify with the soup.
Return the blended mixture to the crockpot and stir well to combine.
Add the chopped kale and parsley, stir in, and turn off the heat.
Let the soup rest for a few minutes to allow the flavors and texture to meld.
Season with a swish of sherry, vinegar, or lemon juice to taste for a bright, tangy finish.
Serve with crusty wheat bread and a sprinkle of Parmesan cheese if desired.

Notes

Blend more or less soup depending on your desired texture.

Swap in spinach for kale if preferred.

Add extra broth if a thinner consistency is desired.

Fresh lemon juice really brightens the flavors.
