Ingredients to make roasted potatoes and onions
- Petite red potatoes
- onion
- salt
- thyme
- garlic powder
- pepper
- olive oil
Slice your petite red potatoes in half or in quarters, if they are larger.
Dice an onion into chunks roughly the same size as the potatoes.
Add your potatoes, onion, and spices to a glass casserole baking dish (this is my favorite dish to use when roasting potatoes).
Add olive oil to coat the potatoes well and toss until combined.
The potatoes may look too oily at first, but that extra oil helps them roast at a high heat and get crispy without losing liquid and burning.
Toss with your hands until all the olive oil and spices coat the potatoes and onions.
How do you make crispy potatoes?
To make your potatoes crispy, you need oil and around 45 minutes to an hour of roasting time.
Be sure to use a pan large enough for the potatoes to be spread out in an even layer.
This will ensure that each potato has the chance to get those crispy edges!
Bake the potatoes and onions at 425 degrees for around an hour, checking to flip and stir every 15 minutes or so.
Each time you flip the potatoes, use a spatula to make sure any edges are scraped from the pan.
This will help get the potatoes evenly cooked and crispy on more sides.
Easy peasy, and always a winner side dish recipe!
Even my husband who claims he doesn’t like potatoes will devour this recipe.

I made these a couple of weeks ago and they were an instant hit with my husband. He requested them for dinner again tonight and the only change he requested was for double the onions! I think we have a hit here.

I made these with 1t fine table salt and though they were good otherwise, they were too salty. Do you use coarse salt or fine?

I want to do these potatoes,but also am roasting a five pound prime rib roast,obviously at a much lower temp. Can I do the potatoes say for 45 minutes,remove from oven,then pop back in for the time remaining to finish them off once I’ve removed my roast?will they be soggy do you think?

I don't know about soggy, but if you roast them at the end at a higher heat it should be fine. I personally like extra crispy potatoes, so cooking them longer may not be a bad thing! Let me know how it works out.
