Secret to great roasted potatoes

What's your secret? My mother-in-law made great ones, but she is no longer around to ask.

    1. I roast on high heat 425-450 for 25-40 min (depending on the size you cut) - did one the other night with little reds, when they came out - tossed with blue cheese and chives. I liked it alot.

      1. I adapt Alice Water's superb roast potatoes -- olive oil, thyme (I throw in whole sprigs) and garlic cloves, S&P and a splash of water -- by covering w/ aluminum foil for first 1/2 hour, and then uncovering for remainder. That way potatoes cook all the way through but have time to brown/crisp up. And the aromatics steaming together makes one fine spud! Make sure there's plenty of room so uncovered the potatoes roast, not steam. 400-425 degrees is about right.

          Parboiling them first.

          That way, they're done in no time and brown to a nice crisp. Toss them after parboiling with olive oil and spices, spread in a glass casserole dish, pop in the oven, and you're good to go.

          1. re: dolores

            Right - and I'll add this. When you toss them with the olive oil and whatnot, don't be gentle. Roughing them up a bit will give the exterior a nice crunchy texture when you roast them.

            1. re: dolores

              Make it faster: Par-nuke them first. Much less mess and time involved. This is also THE key to oven fries of the regular or sweet-potato variety.

              And also salt them before cooking. Potatoes cooked without salt are inedible to me (and unfortunately, I have a lot of them -- neither my father nor sister add any salt at all in home cooking).

              1. re: dolores

                Agree. Parboil or parnuke. But in order for them to really crisp up, you need to make sure they're as dry as possible before roasting. I put them in the preheating oven for a couple of minutes just to dry them out. I toss the potatoes with the oil and a head of garlic cloves that have also been parboiled in a cast iron skillet. I do that on top of the stove until they're really well coated, nestle in a sprig or two of rosemary, then put the skillet in a 450F oven for 30 to 40 minutes. I suspect it's because of the way it retains heat, but the cast iron skillet makes the crispiest potatoes ever.

            2. Here's what I do (similar to Zuni's):

              Cut about 1.5 lbs med sized red or gold potatoes into quarters, put in cold water to cover by about an inch--add two bay leaves and 1 tablespoon of salt. When water comes to boil, boil 6-8 mins (while boiling, preheat oven and casserole at 425-450). Drain and drizzle 1/4 cup olive oil, add about 1 teaspoon salt, 1/2tsp pepper, 1-2 sprigs of bruised rosemary (bang it with the side of your knife), about 1/2 tsp granulated garlic or garlic powder (don't use fresh it'll burn), 1/2 tsp onion powder and 1/2 tsp dry thyme and marjoram. Mix well and place in preheated casserole and roast at 450 for 10 mins, lower to 425 and let roast another 20 mins. They can be kept warm for about a half hour at 175. I use my toaster oven to make these, since I usually make them at the same time as my roast chicken. I've found that the chicken doesn't get as crisp if I do them in the same oven.

              This recipe makes some of the tastiest potatoes that I've ever had. Highly recommend.

              1. My sister in law cooked the best roasties I can remember on Christmas Day. She'd par-boiled, given them a good shake in the pan to rough up the edges, then roasted in goose fat.

                Fabulous.

                And she'd made loads too many - so I went back and kept nibbling on cold ones throughout the day. Equally fabulous.

                  Yes - second the par boiling and roughing up the edges. Get the right type of potatoes (not too waxy not too floury). Preheat oven - 180c in my fan oven (400F in normal non-convection oven?). Peel potatoes and cut into even size chunks (the size you want to eat!). Place in cold salted water just to cover. Bring to boil, lower heat to minimum and cover. Set timer for five minutes. Place a TBSP or two of olive oil/fat (amount of fat depends on how many potatoes) in a roasting tray. Use two trays if you are making loads - the potatoes need to roast not steam. Heat tray(s) with oil for the 5 minutes whilst potatoes are parboiling. After parboil, drain, return cover and give a good shake to rough up edges. Get hot tray(s) with hot oil from oven and toss potatoes about in the oil. Add sea salt (e.g.Maldon) and poss herbs (e.g. rosemary). Roast in oven for 25-30 minutes (fan oven - longer for regular oven - also depends on how big the pieces are of course). You can turn potatoes halfway through - mostly I don't bother!

                  To make this story shorter - keys are: right variety of potato, parboil, rough edges, hot potatoes to hot fat.

                    Or, to save you the trouble themags, just do what I said 2 posts ago.

                      It's not "trouble" to post. For me roast potatoes are potatoes, fat and salt. Nothing like what you posted!
