1. Preheat oven to 400*F. and turn at least once during the baking.
2. Cut potato into wedges. Mix olive oil, paprika, garlic powder, chili powder and onion powder together. Coat potatoes with oil/spice mixture and place on a baking sheet and they need to be turned 1/2 way through baking.
3. Bake for 30-45 minutes in preheated oven. Cooking time and temperature will vary greatly on how thick you cut the wedges.
My Note: Update: bake at 450*F., for 40-45 minutes, and turn at least once during the baking. If you use the 450*F. in the recipe, the fries will burn. I mixed everything in a gallon size ziploc bag. For the spices, I used freshly minced garlic (no onion powder), paprika, cumin, cayenne pepper, and chili powder. I used 6 potatoes (4 russet, 2 sweet) and 1/3 cup oil. I have cut the potatoes into sticks like normal fries and then baked them for 15 minutes, turned them over, and baked for another 15 minutes (the whole time at 425 since they're thinner than wedges), and I must say these are the tastiest fries ever! I also added salt and freshly ground pepper and garlic salt, and didn't measure it out- just kinda put on as much as looked good, and wow, were they tasty! I think the chili powder was what really put them over the top, so don't be shy with it, and remember that seasonings seem to lose some of their flavors when baked (which means put on more than you usually would)!
So, if you cut your wedges small and thin - you will need to cut the temp and cooking time. But if you cut true (thick) wedges - follow the recipes directions (although I strongly encourage flipping the potatoes halfway through the process). For a super easy cleanup - I poured the oil and spices into a gallon size Ziploc bag and mixed it all together until well blended - then I added the cut potatoes and kneaded and shook the bag until all the potatoes were well and evenly coated. Then poured it into a 9x13 glass baking dish lined with foil. Minor adjustments: I used paprika, garlic powder, salt, freshly ground black pepper, a pinch of chili powder - mine is exceptionally potent, and cumin) -- The second time making this recipe I added fresh minced onion - and that was a very tasty addition too!
FOR THOSE WHO THINK THIS RECIPE TOO BLAND: Take one onion for every 3 potatoes. Cut it in half lengthwise and cut it into slivers. Take all ingredients, including the onions, and put them in a zipper bag. Knead and shake until ingredients are thoroughly mixed. Proceed with recipe directions. The onions add quite a bit of zing as well as nutrition!
I use my french fry cutter to cut the potatoes. I don't even measure the spices anymore. I bake them at 400*, for 15 min, then flip and bake for another 15 on the other side. However, I like my fries less on the crispy side, also using the french fry cutter makes all the fries about the same size for uniform cooking.
