Sweet Potatoes with Caramelized Onions

Step 1
Preheat an oven to 450 degrees F (230 degrees C). Scrub and dry the sweet potatoes, then prick several times with a fork and place onto a baking sheet. Bake in the preheated oven until the sweet potatoes are easily pierced with a fork, 50 minutes to 1 hour.

Step 2
Heat the oil in a large skillet over medium heat. Stir in the onion and bell pepper; cook and stir until the onion has softened and turned translucent, about 5 minutes. Reduce heat to medium-low, and continue cooking and stirring until the onion is very tender and dark brown, 20 to 30 minutes more.

Step 3
Split open the baked sweet potatoes and top with the onion mixture, salt, pepper, and a dollop of sour cream.
