Ways to Switch It Up

Common Questions
Can I make this on the stovetop?
Yes, you can simmer everything in a large pot for 30 minutes. Just ensure the chicken is cooked through before shredding it. The slow cooker method is simply more hands-off and convenient.
How do I know when the chicken is done?
The chicken should pull apart easily with two forks. It will reach an internal temperature of 165°F when fully cooked. Six hours on low is usually the perfect sweet spot.
Is this recipe kid-approved?
Most kids love the mild taco-like flavors and the corn. You can leave out the cilantro if they are picky about green flecks. Serve it with extra cheese on top to win them over.
I hope this cozy Slow Cooker Fajita Soup brightens your fall evenings. It is a simple way to nourish yourself during a busy week. Happy cooking!
