Ingredients to make roasted potatoes and onions
- Petite red potatoes
- garlic powder
- 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.

Potatoes and Onions Recipe
- 1 lb. petite red potatoes, halved (see notes)
- 1 onion, diced into chunks
- 1 teaspoon salt
- 2 teaspoon thyme
- 2 teaspoons garlic powder
- 1 teaspoon pepper
- up to 1/4 cup olive oil
- Preheat oven to 425 degrees
- Add potatoes, onions, and spices to a glass casserole dish
- Pour on olive oil to coat well (I used the full 1/4 cup)
- Toss to combine
- Bake at 425 degrees for 50 - 60 minutes, checking to stir and flip every 15 - 20 minutes
My potatoes were very small, so I just halved them. If yours are a bit larger, you may want to quarter them to get smaller pieces (these crisp up better)
