Thanks to mild-mannered baby spinach and silky sautéed leeks, this weeknight-friendly broccoli soup not only gets an extra boost of nutrients like iron and vitamins B and C—it also takes on a most vibrant color of green and boasts a velvety texture without any heavy cream in sight! A drizzle of tangy crème fraîche and a few crunchy pretzel nuggets serve as the finishing touches to this wholesome and warming bowl.

Ingredient Checklist


Instructions Checklist
  • Melt butter in a medium saucepan over medium-high heat. Add leeks and garlic and cook, stirring occasionally, until translucent, about 2 minutes. Stir in mustard, then flour; cook until mixture has a slightly nutty aroma, about 1 minute.

  • Gradually whisk in broth until combined. Add broccoli stems and season with salt and pepper; increase heat to high and bring to a boil, whisking constantly. Add broccoli florets; reduce heat to low and simmer partially covered until broccoli is tender, about 8 minutes. Stir in spinach and cook 1 minute more; remove from heat.

  • Working in batches, purée soup in a blender. Return to pot and reheat over medium-low. Whisk crème fraîche with 1 tablespoon water in a small bowl. Serve soup, drizzled with crème-fraîche mixture and garnished with pretzels.
