This is a recipe idea that came to me in the middle of the night and made me grab my pen and paper. When something like that happens it usually takes me a while to fall back asleep, but this time I drifted back easily, and you can bet that I was dreaming about these French Onion Sloppy Joes!

The ingredient list for making Game Day French Onion Sloppy Joes is short and sweet. You’ll need;

• sweet onions, sliced
• fresh thyme sprigs
• ground beef
• chopped celery
• tomato paste
• brown sugar
• apple cider vinegar
• Swiss cheese slices
• grapeseed oil, or other light oil

• buns

If you want to get fancier and add more ingredients to your ground beef mixture, have at it. I, however, wanted to keep things simple so that the flavor of the thyme infused caramelized onions would shine in this sandwich.

Making the thyme-infused caramelized onions can be done in advance (if needed). The instructions are simple;

• Melt butter and oil in a large, heavy skillet.
• Slice 3 – 4 sweet onions and add them to the skillet, tossing to coat with the butter.

• Make a thyme bundle and add them to the skillet along with the onions.
• Cook the onions over medium heat (stirring occasionally) until they’ve turned a deep golden brown and have cooked down considerably. *Note – this will take approximately 15 minutes.
• Season with salt and pepper. Stir well.
• Remove the thyme bundle from the skillet and use the onions immediately, or store covered in the fridge for up to 4 days.

Here are the fast and simple instructions for making homemade sloppy Joes;

• Brown ground beef and diced celery in a large skillet over medium-high heat. Season with salt and pepper.
• Stir in tomato paste and brown sugar.

• Add a splash of apple cider vinegar and cook, stirring frequently until the beef is no longer pink and the sloppy joes are heated through.
• Serve on buns with a slice of Swiss cheese and mounds of thyme-infused caramelized onions.
