Gather your ingredients and preheat a large heavy-bottomed pot over medium heat.
Add chopped onions, minced garlic, and chopped jalapeño to the pot. Sauté until fragrant and onions are golden, about 5 minutes, with gentle bubbling and a sweet aroma filling the air.
Stir in shredded chicken, diced tomatoes with their juice, cumin, oregano, and smoked paprika. Cook for another 10 minutes, stirring occasionally, until the mixture becomes fragrant and slightly thickened.
Pour in the chicken broth, bringing the mixture to a gentle simmer. Reduce the heat to low and let it bubble softly for 20 minutes, allowing the flavors to meld and the broth to develop a vibrant aroma.
Taste the broth and squeeze in fresh lime juice, then adjust seasoning with salt or more lime as needed, until bright and balanced.
Serve the soup hot, garnished generously with chopped cilantro, with extra lime wedges on the side for squeezing before eating.
