Step 1

Preheat the oven to 400 degrees F (200 degrees C).

Step 2

Place sweet potatoes on a baking sheet. Prick with a knife and drizzle with olive oil; rub to coat. Space sweet potatoes evenly apart.

Step 3

Bake in the preheated oven until completely tender, about 35 minutes.

Step 4

Meanwhile, add bacon to a pan over medium heat. Cook and stir until bacon starts to get crispy and the fat turns foamy, 4 to 5 minutes. Add green onions and jalapeno; cook and stir for 1 minute. Remove from heat and set aside.

Step 5

Let sweet potatoes cool until safe to handle. Leave the oven on. Cut off the top 1/3 of each potato, holding the knife at a 45-degree angle. Scoop out sweet potato flesh from both the top and bottom halves, leaving at least 1/4 inch flesh in the bottoms to make the shells.

Step 6

Season the sweet potato flesh with salt, pepper, and cayenne. Add 1/2 cup cheese, creme fraiche, and lime juice. Mash with a potato masher. Add the bacon mixture and mix until combined. Spoon filling into the sweet potato shells. Lightly scatter remaining cheese on top.

Step 7

Bake until heated through and tops have started to brown, 20 to 25 minutes.
