Wonderful easy Make-Ahead Roasted Rosemary Potatoes for 50
What’s not to like.
There’s no peeling, and just a bit of chopping. You can make this up to 2 days in advance. It re-heats beautifully. And the ultimate test of a great large group recipe? I’ve had several people say, “Wow. I’m going to make a smaller version of this for my family.”
You’ll be using two large (13 x 20 x 3) aluminum roasting pans for each batch to serve 50. Here’s what they look like in one of the pans fresh from the oven.
You can also make these for a smaller crowd (like your family) on a sheet pan just as easily like I’ve done below. They are FANTASTIC. (Disclosure: I really love, love potatoes, so I’m not even remotely a fair judge. But rumor has it, these are very good.) The Family-sized recipe follows the Potatoes for 50 recipe.
I first made this recipe for the 150 person cast and crew of our church’s production of Savior of the World. Three of us each made one batch (one batch uses two aluminum roasting pans) to serve 50. That means for 150 servings we had 6 large (20 x 13 x 2) disposable aluminum pans full of potatoes. You can use a different size pan as long as you don’t use a deeper pan which will increase the cooking time. If you are making more than 2 pans in one oven it will also increase the cooking time by about 15 – 20 minutes.
Multiple members of the cast and crew came back for seconds on the potatoes and when we were done there were none left.
The seasonings make the potatoes!
The biggest problem most people have with potatoes, especially potatoes for a crowd, is they under-season them. Potatoes take a lot of seasoning to really taste good. In my large group recipe, I call for:
- 1 tablespoon dried, chopped rosemary
- 1 tablespoon kosher salt
- 1 tablespoon garlic powder
- 1/4 teaspoon black pepper
for each pan of potatoes. Don’t worry, that’s not too much.
You can certainly use white or yellow onions if sweet are not available. Often white or yellow onions are smaller than the sweet onions, so I’d pick up 3-4 more if you’re using white or yellow.
