Sear the ground beef in a skillet before adding to the slow cooker to develop a rich, caramelized flavor that elevates the entire chili's depth and complexity.

Reserve half your taco seasoning to add during the last 30 minutes of cooking—this preserves the bright spice notes rather than letting them fade into the long simmer.

Always rinse canned beans before adding to remove excess sodium and starches, preventing a cloudy broth and allowing the taco flavors to shine more clearly.

Crisp tortilla strips in a 375°F oven for 8-10 minutes just before serving rather than adding them to the slow cooker, ensuring they stay crunchy and don't become soggy.

Keep sour cream, cheddar cheese, and green onions chilled until the moment of service—the temperature contrast with the hot chili creates better texture and prevents the cheese from separating.
