Loaded Mashed Potato Bites
“Found a great way to use up leftover mashed potatoes. These remind me of those bites that they used to serve at Arby's. Hope you enjoy.” - Adrienne
Chicken And Potato Waffles
“A great spin on traditional chicken and waffles recipe. We loved the savory potato waffles. They are unique and delicious! The brine really tenderizes and adds great flavor to the fried chicken. We opted for beer in the brine, but next time we want to try with the ginger ale for added sweetness. We topped off our chicken and waffles with some maple syrup ... yummy.” - Kitchen Crew
Shepherdess' Pie
“This easy recipe has simple ingredients, yet packs a big punch of flavor. Pepper adds a kick of spice so adjust that to your liking. If you don't have chicken leftovers, pick up a rotisserie chicken at the market. This is a flavorsome and hearty dinner.” - Kitchen Crew
The Old Fashion Potato Candy
“My mother used to make this for us in the middle 1900's and to us it was the best candy we had. I hope you enjoy making it but you need patience as it takes time.” - Leila
Turkey Shepherd Pie
“I tried this yesterday with all my left-overs. I make a meat/sausage stuffing and went into it as well. OMG It was awesome.” - Charlene
Irish Boxty Pancakes
“These pancakes are creamy, rich, and just wonderful. I think they're best when cooked with onion and served savory, but you can also serve them plain with sugar or powdered sugar.” - Jenn
Potato Cake
“Thank you for this recipe. I followed it exactly, and it turned out absolutely perfect.” - Marie
Cheesy Mashed Potato Bake
“Made this easy & delicious dish once again. My only change this time was I used crushed Ritz crackers instead of dried bread crumbs on the bottom of the baking dish. Thanks for the great idea!” - Maria
Potato Cakes
“I made up this recipe back in 1985 when I got my first apartment and was beginning to experiment in the kitchen. I was trying to use leftovers, but I didn't know how to cook. After many years of adjusting the recipe, this is how we make it now. Turns out we love to eat this with breakfast, eggs, bacon, and potato cakes!” - Helene
Quick And Easy Shepherd Pie
“I have made this recipe several times, it is so good!! Just a hint for those who don't have mashed spuds on hand, you can use shredded hash browns or tater tots also. I love this recipe.” - Bev
