1 1/2 lbs yams, cut in fries
2 tablespoons olive oil
1/2 teaspoon salt (plus possibly more to taste)
2 fresh garlic cloves, minced (I grate mine)
1/4 teaspoon red pepper flakes (optional)
1/2 teaspoon lemon zest, finely grated
1 tablespoon fresh lemon juice
1 teaspoon dried basil
Put the oven rack in the middle position and preheat oven to 375 degrees F.
Toss the yam fries with 1 tbsp of the olives oil, 1/4 tsp of the salt and the garlic.
Arrange in one layer on a baking sheet and roast them for 20 minutes.
Meanwhile whisk together the other tbsp of olive oil, the lemon zest, lemon juice, basil and remaning 1/4 tsp salt -- and red pepper flakes if using.
Remove the yam fries from the oven, drizzle over the olive oil/lemon mixture then flip the fries over. You want to flip the fries at this point to help them crisp up as well as distribute the lemon/basil seasonings.
Return to oven and cook for about another 20 minutes until done. I like mine to crisp up a bit so I like to turn on the broiler for the last few minutes.
Spinkle with a little extra salt if you like.
