French Onion Soup - So easy to make this in the crockpot! #SplendaSweeties + #SweetSwaps

As I continue on my quest to be healthy, I’ve started thinking about what I am going to change in the new year. That means taking stock of my life. What is working, what isn’t. My family life is great, and my husband’s health is doing well. There is always some type of “Mommy” stress, but all in all we are doing well. That leaves work and my brain. Yes, my biggest obstacle to health is my own mind. Work definitely has been having an effect and things are going to change on the blog next year. This year I got a hold of my nighttime sweets craving and feel in control of it. I am working on my afternoon snack attack and lunch.

One tip I’ve found for lunch is to have leftovers. Dinner is always healthy, OK almost always healthy. Making a big batch of soup like this Slow Cooker French Onion Soup reaps leftovers for days. That is perfect for enjoying a warm and satisfying lunch. I plan on doing a lot more of this type of cooking, so I can enjoy leftovers for lunch the next day. This particular recipe is also extremely easy. Yes, it does take quite a while to cook, but the hands on time is about 15 minutes. Usually onions are slow cooked on the stove until they are golden brown.

I let the slow cooker do all the work and helped it along with a little SPLENDA® brown sugar blend. Sugar actually helps onions caramelize quicker and with SPLENDA® Sweeteners I don’t get all the calories from sugar.  It is a great swap. I start the onions the night before and let them caramelize while I sleep. In the morning, I simply stir in the remaining ingredients and let all the flavors mingle together until dinner time. It really is that easy.

Since French onion soup is low calorie and healthy, I can add a little indulgence in the way of french bread and melted cheese. What would French onion soup be without that toasty cheese on top? Boring! You will be able to enjoy this soup for days, or freeze it for dinner another night. I am sure you can use a few simple dinners this time of year when there is so much to do. SPLENDA® isn’t just for baking. In addition you can find lots of other ideas in the Sweet Swaps program by SPLENDA® Sweeteners. You can also follow SPLENDA® sweeteners on Facebook, Pinterest, Twitter and Instagram.
