Mustard-Crusted Potatoes-an easy side dish that goes great with any meal! 

Mustard Crusted Potatoes

Josh loves mustard. He’s kind of obsessed. Every time he orders a sandwich from a restaurant he asks for extra mustard. When he gets his sandwich, he is usually disappointed with the amount so he will go back and ask for more. He likes A LOT! I always make sure he has napkins close by when he is eating his mustard heavy sandwiches because I am not going to try and get mustard stains out of his shirts and pants:)

When I saw my friend Heather’s recipe for Mustard-Crusted Potatoes in her new cookbook, Pure Delicious, I knew I had to make them for Josh, the mustard maniac:)

  1. Yum! I love mustard too and these potatoes are calling my name 😉 Can’t wait to try this recipe!

  2. Well, we are actually a non mustard family, that is, wife never buys it and we’ve never used it in anything before! So I guess we’ll have to talk a walk on the wild side and try this. They certainly look super tasty. 

  3. Oh Maria! Thank you so much! I love these potatoes (I am a fellow mustard maniac!) and am so happy that all of your boys enjoyed them. Thank you for sharing!

  4. I just stumbled on to your page and I was going to make some potatoes with steak tonight for the fam. – Gonna try this! Sounds delish.

  5. Ah I loooove how crispy these potatoes look! Definitely one from the book I’ll be making ASAP

  6. These potatoes look so good!! I love the combination of garlic and mustard! 😀

  7. When we were newlyweds my husband made a mustard chicken for us that used similar ingredients.  Serving these mustard potatoes alongside the mustard chicken would be a mustard lovers dream come true.

  8. I got so excited when I saw this because crisp oven-roasted diced potatoes are probably my favorite side dish ever! So simple, yummy, and perfect with almost any meat/seafood main. I usually roast mine with infused olive oil, herbs de provence, salt and pepper, then top with thinly sliced cheese (smoked gouda or fontina) and chives. But I’m always looking for new ways to mix it up, and the mustard sounds amazing!

    Thanks for the inspiration!

  9. I’m with John!  The more mustard then better. And he is right. Folks don’t know what extra mustard means.

  10. i’m with Josh… give me mustard. it sound like josh and i would really not be embarrassed by all the mustard all over our faces and fingernails. these potatoes i’m making tonight….

  11. 1 star
    It’s too much mustard. Even with the potatoes doubled. There need to be other flavors involved here to make this work…I’m just eating mustard at this point. I was curious to try this even though it seemed a bit unusual and I just don’t think the idea works.

    Also, this is not nearly enough baking time for quartered Yukon gold potatoes that haven’t been boiled.
