Warm the olive oil in a skillet over medium heat. Sauté the onion and garlic until soft and fragrant, about 5 minutes.
Toss everything into the crockpot—yes, everything except the lime and cilantro. Give it a stir like you mean it.
Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours. You’ll know it’s ready when the sweet potatoes are tender and the kitchen smells amazing.
Right before serving, squeeze in the lime juice. Stir. Taste. Smile.
Ladle into bowls, top with fresh cilantro if you're feeling fancy, and serve it up hot.
