Preheat the oven to 400 F. Toss the cubed sweet potatoes one Tablespoon of olive oil, ½ teaspoon each of salt, pepper, and smoked paprika. Spread in a single layer on a baking sheet and bake until fork-tender (about 30 minutes).
When the sweet potatoes are almost done roasting, heat a heavy soup pot over medium heat. Add the bacon and cook until crispy, then remove the bacon and leave the fat in the pot. Set the bacon aside.
Add the onion and garlic to the pot, scraping with a wooden spoon to get the bacon bits off of the pot. After one minute, add the apple, chipotle peppers, adobo sauce, and remaining 1½ tsp smoked paprika. Cook for five minutes, or until the apples are fully softened.
Add the (hot) roasted sweet potatoes, cook for one minute, then add the chicken broth. Bring to a boil, then reduce heat and use an immersion blender to blend the soup until smooth. Add more broth as necessary to achieve your desired consistency.
Season with salt and pepper to taste.
Serve with bacon and avocado on top.
