Can I make this chili in a slow cooker?
Yes. Brown the chuck roast and sauté the aromatics on the stovetop, then transfer everything to a slow cooker with the tomatoes, chiles, and spices. Cook on low for 6–8 hours or high for 3–4 hours, then stir in the ground tortilla chips in the final 15 minutes.
How fine should I grind the tortilla chips?
Grind them to a coarse flour consistency—not powder. Larger pieces will incorporate more slowly and give you better control over the final thickness. Taste as you stir them in.
What can I use instead of serrano peppers?
Jalapeños will give milder heat; habaneros or scotch bonnets will make it much hotter. You can also substitute dried chiles like ancho or guajillo, rehydrated and blended into the sauce.
How long does this chili keep?
Store it in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months. Reheat gently on the stovetop over low heat, adding a splash of water if it has thickened too much.
Can I scale this recipe up?
Yes. All ingredients scale proportionally. The cooking time may increase slightly when doubling; add an extra 30 minutes to the simmer if making a larger batch.
