This simple soup pairs back the extras to let the fennel's naturally delicious flavor take center stage. Gluten-free and easily vegan if you use vegetable stock, it's a great go-to fall-winter dinner or dinner party first course that will satisfy a wide range of diets.
Sweat the onions and fennel: Heat the oil in a Dutch oven or large, heavy-bottomed saucepan over medium heat. Add the onion, fennel bulb, and fennel seeds. Cook, stirring occasionally, until translucent, about 15 minutes. Add the garlic and sauté until fragrant, about 1 minute.
Simmer the soup: Add the potatoes and stock. Season with salt and freshly ground black pepper. Increase the heat to high and bring to a boil, then reduce the heat to maintain a simmer. Cook until the potatoes are fork tender, 15 to 20 minutes.
Puree the soup: Blend the soup using an immersion blender, or transfer to a blender, working in batches with the steam cap off, then return to the pan.
Serve: Ladle the soup into bowls. Finish with a drizzle of olive oil, black pepper, and fennel fronds if you’d like.

What to do with fennel stocks? They're a bit too fibrous and tough to eat, but they make a great addition to homemade vegetable broth and chicken stock.
