Ingredients
- 2tablespoons olive oil, plus more for serving
- 1small red or yellow onion, thinly sliced
- Salt and pepper
- 1pound baby potatoes, diced
- 2teaspoons dried oregano
- 1head of broccoli (about 1 ¼ pounds), rough ends trimmed, cut into bite-size pieces
- 1quart (4 cups) low-sodium vegetable broth
- 1cup finely grated Parmesan
Preparation
- Step 1
Heat the oil in a large pot over medium-high until shimmering. Add the onion, season lightly with salt, and cook, stirring occasionally, until starting to soften, about 3 minutes. Add the potatoes and oregano; cook, stirring occasionally, for 2 minutes. Stir in the broccoli, the broth and 2 cups of water. Season lightly with salt and pepper.
- Step 2
Raise the heat to high until the liquid starts to boil. Adjust the heat to maintain a gentle boil with active, medium bubbles breaking across the surface. Cook, stirring occasionally so that nothing is sticking on the bottom, until the potatoes are soft and mashable, about 20 minutes.
- Step 3
Lower the heat to medium-low, hold the pot steady and use a potato masher, a sturdy fork or the back of a wooden spoon against the side of the pot to mash the ingredients together until your desired thickness, leaving some chunks for texture, and cook about 2 minutes more. (Keep in mind that the cheese will thicken the soup slightly.)
- Step 4
Stir in most of the cheese, reserving some for garnish. Taste and add salt if needed. Divide among bowls and top with the remaining cheese, a few grinds of pepper and a drizzle of olive oil.

I have a ton of russet potatoes, and zero "baby potatoes." If I dice them, would russet potatoes work as well as baby potatoes?
No. No need, they're very tender and add interest. I rarely peel any potatoes, even for rustic mashed potatoes. The skin is vitamin-rich, flavorful, and textural.
Step 1-A: For a truly traditional, rustic Italian touch, remember all those little pieces of Parmesan rind you've been saving in the freezer? Add a few of them to the pot now, for both flavor and to aid in thickening!
Mine was pretty bad! The texture was mealy and flavor was overwhelmingly broccoli. I think my potatoes weren’t very tasty to start with bc how bad can potato soup be!?
Can’t you use an immersion blender to blend everything together at the end? Seems simpler than dealing with a potato masher.
I was thinking of adding chick peas for protein. Any thoughts?
