This soup is particularly delicious in the late Fall, after the broccolini has been frost-kissed to bring out its natural sweetness. Further roasting increases the caramelized flavor, and creamy potatoes add the right amount of substance without overdoing the dairy. *For a low-carb option, you can substitute cauliflower for potatoes.
1/4 cup high-heat oil
2 bunches broccolini (~2 pounds), or 2 large heads broccoli
2 tsp. kosher salt
2 tbls. butter/ghee
1 large white or yellow onion, chopped
3 - 4 cloves garlic, chopped
1/4 tsp. fresh ground black pepper
1/4 tsp. crushed red pepper flakes
1 pound potatoes, sliced (peeled or unpeeled), or cauliflower florets.
1 quart stock or water, more as needed for desired consistency
1/4 tsp. lemon zest
1 1/2 tbls. lemon juice
Grated Parmesan cheese, to serve
Parsley, chopped, to serve
Olive oil, to serve
Preheat oven to 400°F.
Toss broccolini with 2 tbls. high-heat oil & 1 tsp. kosher salt. Arrange on a baking sheet in a single layer. If using broccoli heads, cut into florets, & peel/chop the stalks. Roast until a little crispy and browned, but not entirely soft, about 15 minutes.
In a large soup pot, heat butter/ghee & 2 tbls. oil over medium-low heat. Add onions and garlic, black pepper, crushed red pepper flakes, and 1/2 tsp. salt. Cook until softened, about 4 minutes.
Add potato or cauliflower to the pot with stock or water, and remaining salt if needed. Bring to a simmer, cover pot and cook until potato/cauliflower is just tender, (10 - 15 minutes for potatoes, 5 - 10 minutes for cauliflower). Add broccolini, cover again and cook another 5 - 10 minutes.
Add lemon zest and purée soup with an immersion or standing blender, leaving some small chunks for texture. You may need to add more stock or a bit of milk/cream if too thick. Stir in lemon juice. Finish with grated Parmesan cheese, a drizzle of olive oil, & parsley.
