Lightly toast corn tortillas in a dry skillet for 15-20 seconds per side before layering to prevent them from becoming mushy and to enhance their flavor and structural integrity in the slow cooker.

Season your chicken breasts generously with cumin and garlic powder 30 minutes before adding to the slow cooker to allow the spices to penetrate the meat for deeper, more complex flavor throughout.

Use only 1.5 to 2 cups of enchilada sauce instead of the full can—too much liquid will make your lasagna soggy; you can always add more if needed at the end.

Alternate thin layers of sauce, tortillas, shredded chicken, and cheese rather than thick chunks to ensure even heat distribution and prevent dry spots in your slow cooker lasagna.

Reserve fresh cilantro and sour cream to garnish after cooking rather than mixing in beforehand—this preserves their vibrant flavors and adds a cool, refreshing contrast to the warm dish.
