Cream of Onion Soup Substitute
Tired of using salty condensed soups in your casseroles? Then use our homemade cream of onion soup instead and add as little or as much salt as you want!
Imagine digging into a plate of fiesta chicken casserole only to be overwhelmed with the flavor of salt.
But, you can avoid that problem by making your own cream of onion substitute!
Best of all, once you learn to make a cream of soup base, you can use that to create any sort of soup you need. Like cream of bacon soup!
If you need a baking mix recipe, then try our homemade bisquick mix.
How to make cream of onion soup?
Start by combining the flour and milk in a small mixing bowl.
Use your whisk for this step because it will help break up the flour.
Next, grab a medium saucepan and place it over low to medium heat. Place the butter into the pan and let it melt.
After that, add the onions to the pan and let them cook until they’re soft and partially caramelized. Use your wooden spoon to stir them occasionally.
Also, take a look at the photo above as reference for your cream of onion soup.
Now, once the onions have cooked, pour in either vegetable or chicken broth. If you use vegetable broth then the soup is vegetarian.
Go ahead and stir in the garlic powder, smoked paprika, and any salt and pepper you want to add flavor to the soup.
Then, let the ingredients continue to cook until the broth starts to simmer. When that happens, stir in the flour and milk mixture from earlier.
Last, keep stirring for about three to five minutes or until your cream of onion soup has thickened.
Turn off the heat because you are done! That’s it, Kim and I hope you enjoy this recipe and wish you all the best 🙂

I tried your recipe today because I needed a can of Cream of Onion soup and didn’t have any. It tastes pretty close! I wanted to thank you for adding the ingredients within the directions. That is the first time I’ve seen an author do that and it was so helpful! Thank you for helping me with this substitution!
Thank you Angela! We try to make things as easy on our users as possible. We’re glad you like the extra info. Thank you again for commenting and have a great day!
Your print button doesn’t work. It just takes me back to the top. I want to make this. Looks good.

Is this recipe equal to one can of soup?
Hi Rose!
Yes, it’s approximately the same amount. We use it in place of 1 can of cream of onion soup in dishes that call for a 10 ½ ounce can. It works great! Have a great night! 🙂
So thankful, and excited I stumbled across your Cream of Chicken, Cream of Celery, and Cream of Onion Soup Substitutes! Who likes spending all that extra money at the store when you need soup for a casserole! As seniors on a budget, these are a great find and I usually have all the ingredients on hand! I sent hubby to the store and he came back without my cream of onion soup! Rather than give him a lecture or go without making my casserole, I did a google search and you popped up! Yippeee Thanks so much for sharing!
Hi Tracee!
We’re so glad these worked out for you! They work great in casseroles and are so easy to whip up. Thanks so much for the comment, and we hope you have a wonderful week! 🙂
I am curious if you make a large enough batch of this soup if it can be canned and save to have later so that you don’t have to make a new batch each time
Good Morning Maxine, that’s a good question. Unfortunately, we know nothing about canning vegetables, soups, or anything like that. So, I’m unable to answer the question. Kim and I chatted, and we feel like freezing the soup might an option. Also, you might want to try a Google search (if you haven’t already), there might be some information available about canning cream of onion soup. I hope these suggestions help. Thank you for coming by to ask the question. Have a lovely day 🙂
