Common Mistakes to Avoid
When making chili mac casserole, it’s easy to overlook a few key details. Here are some common mistakes and how to avoid them.
- Skipping the Drain: Failing to drain the fat from the beef can make your casserole greasy. Always drain excess fat after cooking the meat for a better texture.
- Overcooking Pasta: Cooking pasta too long can lead to mushy noodles in your casserole. Follow package directions closely for al dente results.
