In a large pot or dutch oven, heat oil over medium heat. Add onion, garlic, chili powder, cumin, and paprika and sauté, stirring regularly until onion is translucent, about 3-4 minutes.: You will hear a faint shimmer and see the oil move more freely when it is ready, that tells you the pan is hot enough to gently sauté. The moderate heat allows the onion and garlic to release sweetness without burning, which would create bitterness. Stirring regularly ensures even softening and prevents hot spots. A common mistake is overheating, which leads to rapid browning; if you notice dark edges, lower the heat and add a splash of broth to deglaze.
Add the shredded chicken, tomato sauce, tomatoes with green chiles, and hominy and mix to combine. Then pour the chicken broth over the top, stir, and bring to a simmer.: As these aromatics cook you'll smell a warm, savory fragrance that signals the spices are blooming, releasing their essential oils into the oil. The onion should lose its raw bite and become soft and slightly glossy, while the garlic turns golden and fragrant. Toasting the spices briefly deepens the flavor foundation of the soup. Watch closely because browned garlic becomes bitter; if the spices look dusty, stir them and reduce heat to prevent scorching. Proper sautéing creates a layered base that makes the broth taste more complex.
Add the tortilla chips and simmer for 15 minutes. While it simmers the chips will disintegrate and help to thicken the soup. Stir in salt 1/4 teaspoon at a time, tasting in between until seasoned to your preference.: When you add these elements the pot fills with savory tomato aroma and you will see the mixture take on a cohesive texture. The shredded chicken absorbs the spice and tomato flavors, while the hominy holds shape and becomes chewy as it warms. Mixing thoroughly ensures even distribution, which prevents pockets of flavor or bland bites. A typical error is dumping ingredients without stirring, which can cause uneven seasoning; fold gently so everything mixes but the chicken remains tender.
Serve warm garnished with your choice of tortilla strips and freshly chopped cilantro.: Pouring the warm or room temperature chicken broth reveals a fragrant steam and creates a simmer that will marry flavors. Aim for small bubbles along the edges, not a rolling boil, so the chicken stays moist and the hominy softens evenly. Simmering melds acidity from the tomatoes and heat from the spices into a cohesive broth. Avoid vigorous boiling, which can toughen the chicken and make the liquid evaporate too quickly; keep it gentle and patient.
Add the tortilla chips and simmer for 15 minutes: As the chips soften, they release starch and corn flavor into the broth, causing it to thicken slightly and gain body. You will notice the broth go from thin to more velvety, and the chips will partially dissolve creating a nice mouthfeel. Stir occasionally to prevent clumping and ensure the chips integrate evenly. A common slip is stirring too vigorously which can break the hominy or shred the chicken excessively; be gentle.
While it simmers the chips will disintegrate and help to thicken the soup: Pay attention to texture changes, the soup should feel more substantial yet still spoonable, not paste like. This natural thickening avoids cream, keeping the bowl lighter while retaining richness. If your chips absorb too much liquid and the soup becomes too thick, add a little extra chicken broth to reach desired consistency. Over thickening is fixable, but under thickening means a less comforting mouthfeel.
Stir in salt 1/4 teaspoon at a time, tasting in between until seasoned to your preference: Salt amplifies flavors, so add gradually and keep tasting to build balance without oversalting. Each addition transforms the profile, revealing sweetness, acidity, and spice. If the canned ingredients were salty, you may need less; conversely, bland broth may need more. If you oversalt, counterbalance with a squeeze of lime or extra unsalted broth rather than adding water, which dilutes flavor.
Serve warm garnished with your choice of tortilla strips and freshly chopped cilantro: The finishing touches provide texture and brightness, the crisp tortilla strips contrast with the tender soup and the cilantro offers herbal lift that smells fresh and citrusy. Serve immediately so the garnishes keep their intended textures. A common misstep is adding crisp toppings too early, which leaves them soggy by serving time; wait until the last moment to garnish for the best experience.
