Preheat oven to 425 degrees, with oven rack in center position. Place a rimmed baking sheet in oven.
Peel and grate potatoes and transfer to a large bowl. Cover by two inches with boiling water. Steep 10 minutes. Drain potatoes in a colander and rinse thoroughly with cold water. Squeeze potatoes with hands to remove excess moisture and transfer back to large bowl.
Add flour, cornstarch, salt, pepper, and egg yolk to bowl and fold into potatoes.
Spread panko on another rimmed baking sheet. With wet hands, pinch tablespoons of potato mixture, form into balls, and toss in panko.
Carefully remove hot baking sheet from oven and coat with 2 tablespoons olive oil. Quickly transfer poppers to baking sheet, drizzle with remaining olive oil, and bake for 30 minutes, flipping once, until golden brown and crispy. Serve with ketchup.
I loved these little poppers! I made this recipe as written, except that after squeezing out the potatoes by hand, I did what LSQ did and squeezed them out one more time by using a kitchen towel. I didn't have any problems with them being mushy. What I will do different next time is add more salt to the potato mixture -- potatoes need a lot of salt -- and I'm going to try adding either fresh chives or dried rosemary for a bit more flavor. I will definitely make these again!
If you follow the directions as written, they'll turn out great. I loved them. I wonder if some that didn't have luck and said they were undercooked maybe made them too big? Whatever the case, they were tasty.
Read the reviews and made some changes... added parm cheese, garlic pwd, onion pwd and some pepper jack cheese.. extra salt and used and egg white instead of yolk. Wow, super yummy. My family loved them.
This has been the only disappointment I've ever had with an LSQ recipe. I watched the episode, then followed the recipe to a tee and it was a complete failure. Crispy on the outside, gummy on the inside and flavorless. I even read the other comments and grated the potato very finely...I cannot imagine someone eating these. What a waste of time and potatoes!
These were okay, but I don't think we'll make them again unless we make some changes. More salt, probably an attempt at a finer grate on the potato. The plus side is that, served with ketchup, they are passable and filling.
Lucinda has great recipes; however, this is not one of them. Neither my husband or myself enjoyed these oven baked poppers. Time isn't an issue if the end product is good. Sorry not a keeper!
