This soup is creamy and rich, and pretty easy to prepare on a busy weeknight. The best part is, it uses a lot of zucchini without tasting like zucchini, a real plus if you’re trying to use up a whole lot of squash! I adapted it from Heidi Swanson’s spinach and zucchini soup recipe, published on her wonderful blog, 101Cookbooks. I replaced the spinach in Heidi’s recipe with peppery arugula, which is plentiful in Central Texas this time of year.
The secret to this soup’s creamy texture is the pureed potatoes in the broth. I recently bought an inexpensive immersion blender (under $20!), which pureed the soup right in the pot and made preparation a breeze. I definitely recommend adding this handy gadget to your holiday wish list if you don’t have one already!
Creamy Summer Squash Soup (serves 6)
1 tablespoon olive oil
2 cloves garlic, chopped
1 bunch shallots, white parts only, chopped
2 cups chopped potatoes (2 medium potatoes)
2 cups chopped summer squash (1 giant squash or 2 medium squash)
4 cups low sodium vegetable stock
3 cups chopped arugula (1 big bunch)
1/4 teaspoon salt
1/2 tablespoon pepper
Sour cream, yogurt, or olive oil to garnish
Chop all the vegetables. If you’re using an immersion blender, be sure the vegetable pieces are less than 1/2 inch so they’ll purée easily later. Heat olive oil over medium high heat in a large soup pot. Add shallots and garlic and sauté until onions are translucent. Stir in the potatoes and zucchini, then pour in the vegetable stock. Bring to a boil and cook for about 15 minutes, until potatoes are soft. Stir in arugula and turn off heat. Puree with an immersion or conventional blender until soup is smooth. Squeeze juice from half the lime into the soup and stir. Taste and season with salt and pepper. I liked lots of pepper in this soup! Serve soup; garnish with lime wedges, a dollop of sour cream or yogurt or a little olive oil, and more cracked pepper to taste.
We loved this soup as a side dish, and ate it for dinner tonight with beer braised bratwurst and onions. A big bowl of soup and half a bratwurst made for a hearty, comforting meal for each of us.
