In a large dutch oven, add a bit of olive oil and the bacon pieces over medium heat. Cook until browned, then remove from the dutch oven and set aside on paper towels. Reserve 2 tablespoons of bacon grease, and drain the rest.
Season chicken breast with 2 teaspoons of salt, and half of the black pepper, oregano, thyme, red pepper flakes, cayenne, and smoked paprika. Save the remaining seasonings for later.
Add the remaining olive oil to the dutch oven on medium-high heat. Add chicken breasts in a single layer, and cook for 5-6 minutes per side until completely cooked through, or until the thickest part of the chicken registers at least 165°F on an instant-read thermometer. Remove from the pot. Allow the chicken to rest for 10 minutes before cutting it into bite-sized pieces.
To the dutch oven, add butter to melt, followed by 2 tablespoons of the reserved bacon grease, carrots, onion, jalapenos, and celery to the pot with a pinch of salt. Cook until the veggies are softened, and the onions are translucent, about 5 minutes. Add garlic, lemon zest, flour, and the remaining spices, and cook until the garlic is fragrant, and the flour no longer smells "raw" or has a floury taste.
Pour in the chicken broth, lemon juice, and Worcestershire sauce, and scrap the bottom to get any extra bits that are stuck to the bottom. Add in the potato, the bay leaves, the chicken pieces, and salt. Bring to a gentle boil, then reduce to a lively simmer and partially cover for 10-15 minutes, until the potatoes are fork tender. Once cooked, remove the bay leaves.
Reduce the heat to low, and stir in the half and half, and the bacon bits. Once the mixture is warmed through, add in the shredded cheese in small batches to melt. Continue stirring until the cheese is completely melted. Adjust seasonings to taste.
Once the cheese has melted, garnish the bowls with chopped parsley, fresh thyme, bacon, more cheese, salt, and pepper. Enjoy!
