Crisp the Bacon: In a large pot, heat over medium-high heat. Add the bacon strips and cook until they are wonderfully crispy. Take the bacon out and let it drain on paper towels. Set it aside for later topping.
Sauté the Veggies: Remove any extra bacon grease from the pot. Add the olive oil, then toss in the diced onion, carrots, and celery. Cook for 3-5 minutes until the onion turns soft and clear. Stir in the minced garlic and paprika, cooking for just one more minute until you can smell its inviting aroma.
Simmer the Soup: Now, add the diced sweet potatoes, 48 ounces of chicken broth, salt, pepper, and the bay leaf to the pot. Bring everything to a boil, then reduce the heat to a gentle simmer. Cover the pot and let it cook for 25-30 minutes, or until the sweet potatoes are fork-tender.
Blend to Perfection: Once the potatoes are soft, use an immersion blender directly in the pot to blend the soup until it's completely smooth and creamy. If you don't have an immersion blender, carefully transfer the soup in batches to a regular blender and blend until silky smooth.
Finish with Creaminess: Stir in the half and half. If you prefer a thinner soup, you can add the remaining broth now (up to 56 oz total). Bring the soup back to a light simmer to ensure it's heated through.
Serve & Enjoy: Turn the heat to low. Ladle the warm soup into bowls. Top generously with the crispy bacon crumbles, a dollop of Greek yogurt or sour cream, shredded cheddar cheese, and fresh green onions. Savor this comforting and healthy meal!
