Have you recuperated from the holidays yet? 
Sometimes I feel like it takes me a good month to get back into the swing of things. A sort of holiday hangover if you will. 
But we all know we have to get back in the saddle right. We’ve got places to go, jobs to do, and people to feed. And, if your people are like my people? They get pretty dang cranky if they don’t get fed! 
However, with the places to go, and jobs to do, getting a nice hot breakfast on the table for everyone can feel like mission impossible. 
 But hey, Tom Cruise ain’t got nothin’ on me! Especially when I have my new secret breakfast weapon, McCormick’s Good Morning breakfast products. They give your breakfast all the flavor it deserves, without a ton of work, and make your family think you are a culinary rock star ? 






Now, y’all know I am a HUGE casserole girl and overnight breakfast casseroles like my Easy Overnight Eggs Benedict Casserole, Make Ahead Ham and Cheese Breakfast Casserole, Chicken and Waffles Casserole, and Strawberries and Cream Cheese French Toast Casserole happen in our house on a pretty regular basis. 
BUT, those have always been reserved for the weekend. The poor weekdays we left to scrambled eggs, cheese omelets, and oatmeal. 
That was until I met my new BFFs. 
I am serious here people ?Kevin thinks he has died and gone to breakfast heaven! 







The Good Morning Slow Cooker seasoning packets add fresh and rich flavor to any egg casserole or French toast, so this drool worthy casserole was thrown together in no time flat.
I mixed the eggs, milk, and cheese, with the McCormick Slow Cooker Mexican Egg Casserole seasoning packet, scattered some hashbrown potatoes in the bottom of my slow cooker, poured in the eggs, set the timer, and I was off  to make some coffee, take my shower, and get everything going for the day. All the while this delicious casserole was cooking away in my slow cooker. All I did was add some chopped tomato and cilantro.
I mean look at it ? this took zero work and gave maximum flavor!
Kevin, the consummate skeptic, gave a little side eye to the casserole as it was cooking ?
Are you making eggs for breakfast?
In the slow cooker?
*insert crickets chirping*
He just doesn’t get it does he?
Oh how his tune changed once he had a bite. 
WOW, this is good…….like really REALLY good!
Oh ye of little faith, would this girl ever steer you wrong? 
I think not since he proceeded to eat over half the dang casserole!! 

So, grab those keys and head on down to Walmart so you can Ease into the morning routine with a breakfast that cooks in the slow cooker. Featuring simple recipes on the package – for everything from egg casseroles to French toast – these seasoning mixes make for warm, hearty breakfast or brunch the whole family can enjoy together. And, they’re gluten free with no artificial colors or MSG.
