How to Make Beefy Tomato Mac Casserole in a Crock Pot
Aunt Lou here.
Michael and I were talking about what I was going to make for dinner this week, and he brought up a recipe he loved when he was a kid that was always brought to pitch-ins. I asked if he remembered everything that was in it, and he did! So, now you have this Crock Pot Beefy Tomato Mac Casserole. It is a simple, yet classic recipe that young and old alike will love.
This recipe below has four servings. However, it can easily be halved for those who only need two servings. It can also be doubled or tripled for anyone who might need to feed a larger crowd. I love it when a recipe works out that it can be tailored to whatever your particular needs are on any given day.
