Ingredients
2 tablespoons olive oil, plus more for serving
1 small red or yellow onion, thinly sliced
Salt and pepper
1 pound baby potatoes, diced
2 teaspoons dried oregano
1 head of broccoli (about 1 ¼ pounds), rough ends trimmed, cut into bite-size pieces
1 quart (4 cups) low-sodium vegetable broth
1 cup 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!
I am in the middle of making this. I used russets because I had nothing else. It looks good but why not use an immersion blender? I had half a chayote so I added that cut up. It’s taking a lot more time to cook than I thought it would. Smells great. Simple recipes always seem to taste better to me.
I’m making this with some modifications due to what I’ve got on hand and comments that inspired me. I’m planning to add 1/2 and 1/2 and grated Parmesan in addition to the rind after I use my immersion blender. I have a cast iron drop in cooking pan that goes from stovetop to slow cooker. I use it frequently as I can sauté and sear in it as well as bring contents to a simmer prior to slow cooking. I added a carrot and smashed and sautéed elephant garlic clove. I used a Mediterranean herb blend and vegetable stock. I deglazed the pan with some good vermouth before adding stock, potatoes and broccoli. I look forward to trying it out. I used freshly ground bourbon barrel smoked black pepper. I have sour cream and chives for garnish. I will adjust salt to taste. I like Himalayan Pink salt for general purpose use with a few others for specialty uses.
Made this per the instructions but had a hint of bitterness. Any ideas to rectify? I have some leftovers I’d like to use
