How to make French Onion Soup Lower Carb
Traditional French Onion Soup has the big slice of toasted French bread under the cheese that is broiled under the broiler. We skipped the bread completely to keep it gluten-free and did not add any potatoes to keep it a bit lower carb. If you wanted to really make it keto friendly then use lower carb veggies like green beans, spinach, cauliflower, bok choy, etc and skip the red wine for deglazing.
Refrigerator Clean Out Day Makes the Best Soups
We started out by caramelizing our onions in a pot and then deglazing the pan with a little red wine and then added the shredded beef and all those delicious slow cooker pan drippings from our Crazy Easy Italian Slow Cooker Pot Roast Recipe and whatever veggies we had in the crisper or freezer. This soup is really a reflection of whatever you have in your crisper, “Clean out the Refrigerator Day Soup”. We could not name the recipe “Clean out the Refrigerator Day Soup”, but indeed that is exactly what it is. What little bits and bobs of vegetables and meats do you have in your refrigerator to make a delicious bowl of French Beef Vegetable Mushroom Onion Soup? Another great recipe for clean out the refrigerator day, is our Pantry Fried Rice. We make that often.
What kinds of Vegetables to Add to the Soup
I do not suggest making your soup with canned vegetables, if you are concerned about nutrition as they are filled with sodium and other preservatives. However, frozen vegetables on the other hand are a great solution as if you buy just the plain frozen vegetables they are just the vegetable. Read the label. In the winter, your access to all the fresh vegetables may not be available. However, there is always frozen and this is a great alternative.
Stay Healthy - Enjoy Soups
This is the time of year that you need to take extra good care of yourself to avoid the colds and flu season and boost your immunity.
