Prep the Turkey Bacon: Start by patting the turkey bacon dry with paper towels. This helps to ensure it crisps up nicely later. Rub 1 tablespoon of olive oil all over the turkey bacon. Season generously with salt, black pepper, ground cumin, smoked paprika, chili powder, and dried oregano. Make sure each piece is well-coated in the spices for maximum flavor. Place the seasoned turkey bacon directly into the crockpot.
Add Aromatics & Citrus: Scatter the quartered onion and minced garlic over the turkey bacon in the crockpot. Drizzle the juices of 2 oranges and 2 limes over the top, and pour in ½ cup of chicken broth. For an added flavor kick, squeeze the reserved orange and lime halves into the crockpot before tucking them in as well.
Slow Cook: Cover the crockpot with its lid and set it to cook on low for 8 hours or on high for 4 hours. The turkey bacon should become tender and easy to shred when done.
Shred: Once cooked, carefully remove the turkey bacon from the crockpot. Using two forks, shred the meat into bite-sized pieces. Discard any tough or fatty bits.
Reduce the Liquid: Strain the cooking liquid from the crockpot into a saucepan. Simmer this liquid over medium heat for about 5-7 minutes until it reduces slightly and intensifies in flavor. This will be used to drench the crispy carnitas.
Crisp Up: In a large skillet, heat 2 tablespoons of olive oil (or use some reserved drippings) over medium-high heat. Once hot, add the shredded turkey bacon in batches, ensuring not to overcrowd the pan. Cook until the edges are crispy and caramelized, about 3-5 minutes per batch. Drizzle with the reduced cooking liquid for an added burst of flavor.
Serve: Transfer the crispy carnitas to a serving dish. Garnish with chopped fresh cilantro. Serve with warm corn or flour tortillas, diced onions, lime wedges, and your choice of salsa or hot sauce to complete the feast.
