Buttered Miso Roasted Potatoes

So, I have a new oven.

This new addition to my home is many things. It is also NOT many things.

My new oven is NOT: 30 years old. Or a double oven, in which only one oven works. Or a double oven with a door falling off. Or with two doors falling off.

My new oven is not a POS in a rental. It is not entirely uneven in its heating pattern, and it is not the worst in the world.

The old one? Yeah, it was all of those things.

My new oven? In a word, it is amazing.

I know, I know – I am such a weirdo. I’m fawning over my new kitchen appliance. But some of you kitchen freaks have got to feel me on this one.

I mean, how many of us have lived with the crappiest cooking equipment on the whole planet? I bet more than a few of you have. So, you feel my pain.

And you also feel my elation – or can imagine it at least – at having an oven that cooks evenly, even if I don’t rotate the pan, and doesn’t leak so much heat that you turn it on to warm your house. It’s wonderful!

I’m just getting back into the swing of things with cooking (there have been lots of noodles with red sauce, and rice and veggies, around these parts lately), but I can feel that Señor Oven and I are going to be good friends.

Now, on to the Buttered Miso Roasted Potatoes Recipe…

I love love love this recipe. When I began making these last night, I knew I wanted something subtly salty-sweet, but most with pure potato goodness shining through.

Miso instantly popped into my head, and I knew it had to be paired with butter. I don’t usually cook with regular ‘ol butter, but we had some in our fridge that was left over from the wedding, so I decided to go for it.

If you usually use Earth Balance or some other type of vegan margarine, I can’t guarantee that it’ll work exactly the same way for this recipe.

I’m just not entirely sure how it would fare at 400°F for half an hour. But, since butter tends to burn more quickly than oil, you should be alright. If you give it a go, be sure to let me know!

I paired the miso butter sauce with some dried sage and fresh chopped rosemary, and added a pinch of salt.

If you try the sauce before smothering your potatoes with it, it might seem a bit salty – that’s okay. The salty flavor mellows out when it is spread over the spuds, and isn’t at all overly salty when it comes out of the oven.

While the potatoes cooked, I tossed a bit of broccolini in a pan and sauteed it a bit. This was a great addition to make it a complete veg meal (though a bit lacking in protein), but unfortunately the vegetables were a bit bitter.

Not my favorite! At least they were organic.

After just 30 minutes in the oven, the spuds come out slightly crispy and so tender in the middle. Perfect-o.

One thing I didn’t anticipate was the miso blackening on the sides of the pan, but that’s okay. It didn’t taste burnt at all, so don’t let that scare you away. My Chief Dishwasher (also known as The Man) told me it came off the baking dish right easy, so don’t worry too much about that, either.

And the Result?

These came out just as I had expected they would – subtly salty-sweet, full of potatoey flavor, and bursting with the flavor of fresh rosemary.

This is my new favorite potato recipe. It would go so well with a bowl of chili, a homemade coleslaw, or some roasted Brussels sprouts. So many delicious pairings!

That’s the beauty of this dish – it makes a perfect side or a filling main, whatever suits your fancy. And it’s all ready in under 40 minutes, which means it fits into the “Weeknight Meal” category for sure. Huzzah!

  1. Brilliant! I am such a fan of using miso in all sorts of creative ways – it just adds that perfect bit of umph to something! Though I never thought to use them with potatoes… I’m SO trying this! Pinned.

    • Hi Kathleen, thanks so much! You are so right about miso.. whenever I think a dish just needs something, but I don’t know what, miso is usually a good place to start!

  2. I second the idea that miso is always a great go-to… it adds so much to a dish. These look really good, definitely pinning them! I also know how you feel about that oven, nothing could be more exciting for a cook 🙂

  3. what kind of oven did you get? I have been researching but not finding an oven with good reputations. I have a beautiful enameled 1930 oven that my husband changed to propane that I loved but it’s done baking after much service

  4. Miso on potatoes?? Genius!!! I am so with you Raquel, I could eat miso on anything! These look incredible, and I can’t wait to try them. You may have also created the perfect venue for me to get Keith on the miso bandwagon…. Yay!

    • Thanks so much, Jackie! You just gotta sneak that miso in there and let him love it… and then let him know that it’s miso later! He’ll be a convert real quick 😉
