Roasted Sweet Potatoes





Introduction: Roasted Sweet Potatoes

About: I've been posting Instructables since the site's inception, and now build other things at Autodesk. Follow me for food and more!

A labor-saving alternate preparation of a favorite Thanksgiving tuber.

Step 1: Chop Ingredients

2 large onions, coarsely chopped
~2 lbs sweet potatoes, sliced thinly
handful garlic, coarsely chopped
1-2 stems rosemary, chopped
salt & pepper to taste
heavy drizzle of olive oil

Combine ingredients in a 9x13" pan.

Step 2: Mix

Hands work the best here; if you try to use a spoon, fork, or spatula you'll be chasing escapees across the counter.

Check the seasoning by giving one of your fingers a lick on the way to the sink. It should be reasonably salty, because the sweet potatoes suck up salt as they cook.

Cover the pan in foil; at this point you can set it aside in a cool place while you prepare the rest of your Thanksgiving dinner. You can even do it a couple of days in advance, though I'd recommend adding a bit of lemon juice to the mix to help prevent oxidation.

Step 3: Bake

Bake the foil-covered pan at 350F until the potatoes are barely fork-tender, then remove the foil and bake another 10-15 minutes.

Step 4: Serve

Serve warm.

Leftovers save extremely well, and are particularly good additions to omelettes or scrambled eggs.

    Looks delicious. This is similar to a recipe I use. If I am short on time, I microwave it until fork soft, then put it in a large pan and cook it on the stove-top until it get a crust. Don't stir too often or you will make them mushy.

    30 minutes? an hour?  You didn't say how long to bake before uncovering.

    I love sweet potatoes. If somebody were to make this recipe for me, I would probably love it. My usual method of preparation, however, is to just chop the sweet potatoes into cubes and boil them. I've been wanting to try both chips and french fries made out of sweet potatoes, but I haven't yet.

    I think you'll find there's a bit more flavour if you bake them, rather than boil them - go on - have a go, it's delicious!

    stop stop stop! my stomach's growling!

    I stand corrected. Apparently my confusion is the result of some slick talking,fancy dudes in "Marketing". I hate those bastards.

    Just from the picture,they appear as sweet potatoes to me. Had to double check resources though and found the following info: The yam tuber has a brown or black skin which resembles the bark of a tree and off-white, purple or red flesh, depending on the variety. They are at home growing in tropical climates, primarily in South America, Africa, and the Caribbean.
    Yams contain more natural sugar than sweet potatoes and have a higher moisture content. They are also marketed by their Spanish names, boniato and ñame (

    Try sweet potato tempura - yummy.

    i love your instructable site and particularly appreciate the recipies for their clarity and yumminess!

    Thank you! I'm glad you enjoy them.

    Sweet potato CHIPS are good, too! I think I'm tryin' this recipe...

    I love sweet potatoes.... and that looks delicious. Have you ever tried sweet potatoes with maple syrup?

    I haven't, though I love both individually. Wouldn't the maple syrup make them too sweet?

    You only add a little bit of syrup (depends on your taste buds and how many potatoes :P ) which would be just enough to give the potatoes that extra kick.

    Have you ever tried sweet potatoes french fries? Very tasty!!

    Those are good! I don't understand why they're not the standard variety- they're so much tastier.
