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?

3 Ingredient Crunchy Roasted Potatoes from The Food Charlatan

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.
