These tender roasted potatoes and onions 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?

Potatoes and Onions

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.)

Lipton Onion Soup Potates

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.

How to make Roasted Potatoes and Onions

Lipton Onion Potatoes

Onion Soup Mix Potatoes

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 roasted potatoes and onions 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 a Lipton 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!
