FAQs
Can I use ground turkey or chicken instead of beef?
Yes, ground turkey or chicken can be used as a leaner alternative. Just be sure to cook it thoroughly and drain any excess liquid before adding the other ingredients.
Is it necessary to drain the fat after browning the beef?
Draining the fat helps reduce excess grease and keeps the casserole from becoming too oily, but if you prefer a richer flavor, you can leave some fat in the skillet.
