Skillet Roasted Potatoes with Mushrooms, Caramelized Onions and Parmesan


Skillet Roasted Potatoes with Caramelized Onions Parmesan and rosemary_

I fell in love with side dishes during the three years I spent as a vegetarian. When you don’t eat meat, you tend to go into any holiday celebration or dinner party knowing that your meal will be made up of side dishes and you just hope to end up with more than a garden salad and a dinner roll.

Even though I now eat meat, I want hearty side dishes that can be meals all on their own. I still eat vegetarian food regularly (of the 13 recipes I’ve posted this year 11 have been vegetarian and 7 of those have been vegan) and I want the side dishes I serve to be as important and well crafted as the main dish. Vegetables tend to be the star of the side dish, and being a veggie devotee for three years gave me profound respect for what produce can bring to the table. If you’ve never been a vegetarian, and want to challenge yourself in the kitchen, try to go a month without meat. Even if it’s temporary, it’ll grown you as a cook.

This is a recipe that I already have plans to make again. It has an elegant comfort food vibe to it. The edges get a bit crispy, but the middle has a creamy mashed potato feel. Meat eater or not, this can be a meal or a side dish. I really hope you love it as much as I do.

Skillet Roasted Potatoes with Mushrooms, Caramelized Onions and Parmesan


For the onions:

  • 1 yellow onion, thinly sliced
  • 1 tbs butter
  • 1 tbs olive oil

For the Potatoes:

  • 1 lb red potatoes
  • 1 tbs unsalted butter
  • 1 tbs olive oil
  • salt and pepper
  • ½ tsp rosemary, minced
  • ¼ cup parmesan

For the Mushrooms:

  • 8 ounces mushrooms
  • 1 tbs olive oil


  1. Preheat oven to 450.
  2. In a large skillet, melt 1 tbs butter and 1 tbs olive oil. Add the onions and cook over low to medium heat until caramelized and a deep amber color, about 30 minutes. Do not turn the heat too high or the onions will burn.
  3. Slice the potatoes into thin 1/8 inch slices. Melt the butter with the olive oil in a 9-inch cast iron skillet. Swirl the pan to distribute evenly, and pour off into a small bowl.
  4. Cover the skillet with a layer of the potato slices, overlapping them. Brush the potatoes with half of the remaining butter mixture, sprinkle with half of the rosemary, and then with salt and pepper. Layer the remaining potatoes in a second even layer, brush with remaining butter sprinkle with remaining rosemary, then with salt and pepper.
  5. Heat the skillet over moderately high heat until it begins to sizzle, transfer the skillet to the middle of a 450° oven, and bake for 25 minutes, or until golden and the potatoes are tender.
  6. Place the mushrooms on a baking sheet, drizzle with olive oil, toss to coat. Roast mushrooms at 450 until dark and soft, about 10 minutes.
  7. Top potatoes with caramelized onions, mushrooms and Parmesan cheese. Serve immediately.Skillet Roasted Potatoes with Caramelized Onions Parmesan and rosemary TS

Totally agree, sides are important especially at the holidays for me and I love trying to put a piece of everything on my fork 🙂 This would be awesome with an egg on top too!


Jackie February 26, 2013 um 8:23 am

OMG, and egg with a runny yolk would be amazing. That might be my next Saturday Breakfast.

I need more skillet recipes and this one is perfect! I have been on a caramelized onions kick lately! Pinning!


Jackie February 26, 2013 um 8:25 am

I make so many recipes in that skillet! When I was compiling my book I realized that about 4 of my chicken recipes used a cast iron skillet. It just gets such great flavors and textures. Love it.


claire @ the realistic nutritionist February 26, 2013 um 8:47 am

that is one sexy side dish!

I eat meat from time to time but I love vegetarian recipes, especially when Jason is up in San Francisco. I can definitely make these skillet potatoes a meal in and of itself with an oozing yolk on top. YUM!


Cassie | Bake Your Day February 26, 2013 um 4:54 pm

I eat meat a few times per week but I would, in an instant, eat this as a main dish. I love these flavors, my friend!


Julie @ Table for Two February 26, 2013 um 5:30 pm

I like meat but I hate when the side dishes don’t hold their own – this looks wonderful, I love cooking in my cast-iron skillet!


Bree {Skinny Mommy} February 27, 2013 um 7:31 am

Love the caramelized onions in this dish! I would have no problem eating this as a main course!

I think I could eat caramelized onions on everything!


Charity February 28, 2013 um 10:47 am

It’s awesome! I loved it and so did my husband. We ate it as a meal.

This looks amazing! I am such a big fan of mushrooms, Patrick is not sadly….but I think I can sneak this gorgeous dish while he is out of town. How delicious!


Stephanie @ Eat. Drink. Love. March 1, 2013 um 11:20 pm

I’m with you on the vegetarian thing. I used to be vegetarian when I was in high school, but stopped when I was in college. I enjoy meat now, but I still don’t like to eat a lot of meat. This would totally be a main dish for me!


addie | culicurious March 4, 2013 um 10:14 am

I tend to eat vegetarian frequently as well. Love the way this looks 🙂


teyanna March 17, 2013 um 6:53 am
