Golden Onion Casserole with Thyme and Toasted Bread Rounds

Reminiscent of French Onion Soup, this Golden Onion Casserole with Thyme and Toasted Bread Rounds is rich with caramelized onions in a creamy sauce topped with toasted bread rounds. Absolutely delicious!

When I was approached by Swanson® to work with them again this year as a Brand Ambassador, I was delighted to have the opportunity a second year in a row. With their newest offerings that include Organic Chicken and Beef Broths and Stocks they’re able to satisfy both my own and my friends demands for more organic foods with a brand I already know and trust.

Win-win right? I loved this Golden Onion Casserole with Thyme and Toasted Bread Rounds so much I’m sharing it on the Food Network today too…be sure to check out the other recipes from friends at the bottom of the post.

I was asked to highlight a unique way to add a twist to a Thanksgiving classic that family and friends will love. Last year I updated a dish for Thanksgiving and it was a tossup between two I wanted to feature. I ended up sharing these Baked Mushrooms in a Parmesan Cream Sauce but was sad I had to choose so this year was simple.

I’ve taken another old recipe and made a few twists and the results in this Golden Onion Casserole with Thyme and Toasted Bread Rounds were stellar.

My only problem was a simple one. I couldn’t find my recipe! I haven’t made this since a move and I have books and notes and recipes everywhere but no luck. No problem, I thought for sure I had a version on my site from ‘the olden days’ when I would just post a recipe and nothing more. No photos, no story, just a recipe.

My blog started in 1995 as a way to simply categorize and share with friends and relatives so I still have some of those simple recipes onboard. But no…it wasn’t there. Then I had a moment of clarity and remembered ‘The Wayback Machine.’ Have you ever been there? It’s an archive of websites and I knew my site was there and this page from May of 2005 saved the day!

Now that I had found the original it was time to update it a bit. I’ve modified several things; substituting Swanson® Certified Organic Chicken Broth in lieu of the boullion granules and half of the milk and using white instead of red wine. I also added fresh thyme (my herbs are still thriving in Denver’s warm weather!), and a blend of Italian cheeses instead of Gruyere or Swiss because it’s what I had on hand but you can use any of those choices.

I also changed the recipe up a bit for convenience using one pan for everything and eliminating one pot for cleanup. And it was perfect. Don’t tell but I had some for breakfast. English Muffins will never measure up again!

I put the recipe together the night before I took photos as I had run out of enough daylight and I’m glad it worked out that way as I want to recommend that for holiday preparations. I baked it for 8 minutes just to remove the chill; then topped it with the buttered bread rounds and completed the standard baking time.

Making and preparing the meal in one pot that can do the work both on the stove-top and in the oven was key to making this an easy recipe to prepare. I was INCREDIBLY fortunate that my friends at Swanson® gifted me with this beautiful signature blue pan from Le Creuset; it could not have been more perfect.

Functional both in preparation and after, it’s amazing how warm food stays with the lid on top…not that this dish will be around for long. Think French Onion Soup but in casserole form. To die for. Not kidding.

I know we all have important holiday traditions and that preparing and serving some standard recipes are important. Still, if you’re like me and like to add something new once in awhile, this would be a great one to make an appearance.

I can promise you that your family and/or guests will love it so much that they will want it to appear every year just like mine do. And then of course if there are any leftovers…you sure have a great breakfast treat; I know this for a fact. 🙂

  1. Didn’t anyone else realize that it says “add the thyme” but thyme isn’t in the ingredients list except as a garnish at the end? How much thyme do you add to the onions and butter?

    1. Oops…fixed that now; the original recipe did not call for it so I threw some in and yes, forgot to add that ingredient to the ingredients list. I also corrected the amount of butter; it takes a lot!

  2. this looks great, thanks for digging this up in the wayback time machine, love how all of this looks like it will likely combine with the melted cheese in tasty affiliation with the onions and bread rounds!

    1. I have to head back over there…still things I have not redone yet and whoa is it time! This one is so delicious; absolutely needs to be made!

  3. Since we share a love of Famous-Barr French Onion Soup, this has to be the next best thing. Got to try this for the day after Thanksgiving as I always run out of stuffing. And looks a lot easier than Fondue when you are serving family. Thanks for resurrecting this.

    1. I made the soup for a neighbor and he liked it…but he LOVED this so I think it will stand the test. Hope you do too!

    1. It tastes so similar to French Onion Soup but it’s thicker and richer and the thyme was a nice touch. I love it so much I had to call a friend to come get some…a bit too rich for me to finish it off!
