Breakfast Casserole Overnight

Introducing an easy-to-make breakfast casserole

We love to have out of town guests over. Sometimes we serve a breakfast bake because both kids and adults devour it. Other times, I make this overnight breakfast casserole recipe in our slow cooker. Both are equally satisfying. I will admit that I do love the ease of putting all the ingredients into a crockpot the night before. The recipe will transform the aroma of your home. The moment I woke up, I was craving a taste and so were our guests. The work is already done and now the fun part begins! Enjoy such a dish is a pure treat!

    Any tips on if you want to do it the night before so it would be ready about 8:00 am?
    Sounds delicious!

It really works! We tried making these colored ice It really works! We tried making these colored ice balls and succeeded. It’s so simple. Fill up water balloons with water and squeeze a few drops of food coloring in them. Tie and place water balloons outside until frozen solid. It took us 12-18 hours from last night when it wasn’t as cold as it is today. Once frozen cut the balloon off and then you have beautiful solid colored ice balls! #kidsactivitiesathome #snowdayactivities #snowday #texasweather #snowcrafts #boredombusters
