3 Ingredient Roasted Potatoes with Crunchy Onions

These tender potatoes are done SO fast, because instead of adding a whole bunch of spices to make them delicious, you just dump on some onion soup mix and throw it in the oven. The dehydrated onions get all crunchy and glorious! Perfect side dish for Thanksgiving!

What do you do when you can’t fall asleep at night? Do you stay in bed? Read a book? Get up and do the dishes? Count sheep?

I’m one of those lucky people. I rarely have problems falling asleep. But last night at 3am I was awoken by a contraction and my muddled brain was CONVINCED I was going into labor. (one measly contraction people. ONE.) I could not shut my brain off. I decided October 27 was a great day to have a birthday. (ONE CONTRACTION.)

Eventually I decided I needed something to lull me to sleep and I picked Numbers. Numbers, like, Old Testament style. Did you know you can listen to the scriptures on the LDS Library app? Even if you’re not Mormon you should check it out, it’s pretty nice to be able to listen to the Bible (King James version) whenever you want. It’s free.

It did work eventually, but it took me 18 chapters, drifting in and out. I still don’t have a baby, by the way, in case you were wondering.

Last year we visited Eric’s Aunt Linda, who is a fabulous cook. (She’s my legendary mother-in-law‘s sister, so I think it’s in their blood.) She made us these potatoes and I think I was that awkward house guest who’s still eating dinner’s side dish with my fingers during dessert time. (Sorry I’m such a gross guest, Linda.)

I begged the recipe off her, and she told me how she made it: tiny potatoes, oil, and an onion soup mix. Genius!! It is so good. The dehydrated onions get all crisp and crunchy. It is the perfect (easy!) side dish for Thanksgiving this year!

3 Ingredient Roasted Potatoes with Crunchy Onions

Yield: Serves 5-6

Recipe from Eric's Aunt Linda. Thanks Linda!


  • 2 pounds baby red potatoes*
  • 1/3 cup olive oil
  • 1 (1 ounce) package onion soup mix (dry)


  1. Preheat your oven to 400 degrees F.
  2. Slice the potatoes in half or quarters. Just make sure they are all about the same size.
  3. Add the potatoes to a medium bowl.
  4. Add the oil and soup mix and stir.
  5. Line a large baking sheet with aluminum foil and spray with nonstick spray.**
  6. Roast in the preheated oven for 20-25 minutes, turning the potatoes halfway through. Take them out when they are fork tender.
  7. Serve hot!


*Or you could use fingerling potatoes, Yukon gold, or any potato with a tender skin.

**Or use a bit of the oil from the bowl to grease the pan. You would think that with the oil coating the potatoes you wouldn't need to grease the pan, right?? I swear ever time I don't though, my potatoes stick. Maybe I'm crazy.

    How come I’ve never seen this recipe before? Linda’s been holding back! Thanks for sharing Karen! Sorry about the contraction. 🙃

    • says

      She IS holding out on you Kris! She fed us these when we were on our way to your house last Christmas, alongside another chicken dish that was AMAZING but I can’t remember what it was now. I need to track that recipe down too! So many things to make, so little time!

    my dad has been making a dish like this for awhile, and when i moved out he gave me the recipe. i do half potatoes and half butternut squash, and a couple of bone in skin on chicken breasts. mix it all with the oil and soup mix and put the veg on the bottom and the chicken on top. dinner in one dish! so good when it gets cold out :)

    also, i’m always jealous of how fast my partner falls asleep. he’ll be like “i need to take a nap” and in literally two seconds he’s fast asleep. i watch him do it because i’m so fascinated, lol. me on the other hand…while i can’t stay awake through a movie to save my life anymore (why?!), actually trying to go to sleep takes time. we always put on an episode of star trek (any variety) first. if i wake up and really can’t get back to sleep though after trying for a bit, i get on my phone and play one of my word games. (i turn the brightness all the way down and i have a nightshift light set up so the little light that does emit is yellow instead of blue.) 7 little words or red herring usually. there’s no timer, no points, no social aspect so it’s totally stress free. helps my brain focus on something mundane so i can get back into rest mode :)

      butternut and chicken!! That sounds amazing! Awesome one pan meal! Totally trying that. And I fall asleep in movies all the time these days too!!! What is wrong with us?? Maybe I’ll try some of your tactics tonight to get some z’s :)

  3. stephanie says

    oh and YES, the potatoes do stick! it doesn’t make any sense, but it happens. i foil the casserole and…if i remember, i spray it with pam. but sometimes i don’t. (okay a lot of times.) it still comes out so good though.

  4. Linda Heins says

    Finally….. I’m semi-famous! Ha! I’ve got one up on my sister. As for the fabulous cook – I’m not. In fact, our very special Sunday evening dinner tonight was leftover pizza and bagged salad. I sure pulled the wool over your eyes. I’m glad I finally made the blog though. Whenever you need the chicken recipe let me know… it’s a
    Heins family fave ….even Jasper knows how to make it.
    I’ll be sharing this on Wild Purls weekly email this week, so I can be famous at work too.

    • says

      Hey leftover pizza and bagged salad is one of my specialties Linda, don’t be a hater :) And WHOA a recipe that Jasper knows how to make that isn’t PB&J?? Shocking.

      And yes be sure to lie to everyone at work about how “famous” I am, and how famous you are now by association. hehe! Thanks again for sharing the recipe!!

      I love how we talk about “shutting our brain off” like it’s a switch or something. I said the same thing up there. Wouldn’t it be awesome if there were really a switch?? Like C3P-0 style.

      10 pounds!! Oh man. I was 10 and 1/2 pounds when I was born and it wasn’t until I had my first baby (a measly 7 lbs) that I truly appreciated how horrible that must have been for my dear old mom. Let’s hope I have my baby before she gets too huge!

      And I agree roasted anything is where it’s at. Thanks so much Anna!

    Eeks, I always have so much trouble falling asleep during the third trimester with my kiddos. Oh my goodness, so exciting how close you are! Keeping you in my thoughts for an easy and smooth labor. These potatoes look insanely delicious and I love that there are only 3 ingredients!

    • says

      Thank you so much Kelly! I really do feel lucky that I don’t struggle with sleeping usually, I know that’s such a huge issue for so many pregnant women. All my problems are in the first trimester, after that I can’t complain. (except that I wrote a blog post complaining about it so…….oops.) haha!
