How to Make Loaded Fries
Wondering how to make this holiday leftovers recipe? It's easy! Just follow this step-by-step photo tutorial. Then, scroll down for the recipe card for the full ingredients list and recipe method.
Toss the French fries in the dried sage and thyme. Cook according to pack instructions.
Meanwhile, melt the butter in a pan, then stir in the flour and cook for 1 minute. Slowly add the milk, whisking, until it’s all incorporated and thick. Stir in the cheese to melt. Set aside.
Heat 1 tablespoon of oil in a pan and add the shredded Brussels sprouts and sauté until the Brussels sprouts are tender and starting to get crispy.
In another pan, add the veggie sausages, bacon and chicken (ensure all are ready to eat or pre-cook first) and saute until it’s all warm.
Arrange the French Fries on a platter and layer with half the cheese sauce, then pile on the sprouts mixture, and the meats.
Add the remaining cheese sauce and drizzle with the mayonnaise mixed with smoked paprika. Top with chopped parsley. Serve and enjoy.
Do not top the fries until all toppings are cooked and ready as you do not want the cooked fries to get soggy.
It’s important to crisp up your leftovers with oil in a pan to make sure they complement the texture of the french fries.
Use whatever leftovers you have from the holidays.
Try adding crumbled cheeses on top, like blue cheese or gouda.
If you're staring at the fridge, wondering how to use up Christmas leftovers (or Thanksgiving!), then this is an easy way to do it.
Have some Christmas Tree Cookies or Gingerbread Brownies for dessert after a dinner of leftovers.
Pair with a salad like this Rosolli Finnish Beetroot Salad - a popular Christmas salad from Finland.
Make these Mac & Cheese Balls as a great finger food addition to dinner.
Add some cayenne pepper to the sage and thyme for a bit of a spicy french fry.
Make some caramelized onions to top loaded onto the fries for a great kick of flavor.
Make this dish extra veggie heavy by loading on some thinly sliced sauteed bell peppers and mushrooms.
Replace the smoked paprika in the mayo with your favorite seasoning.
Try a dollop of cranberry sauce for even more festive flavor.
Storing: It is best if this dish is eaten immediately as the toppings and fries will not reheat correctly if they are all together.
Freezing: Christmas Leftover Loaded Fries cannot be frozen.
Absolutely! Place everything on a baking sheet, toss with oil and bake at 325 for about 15-20 minutes or until warmed through and desired crisp level is reached.
They are best baked in the oven like in this recipe. You could also use your air fryer for a faster cooking time.
