1 teaspoon dried thyme
Salt and pepper to taste

How to Store Irresistible French Onion Beef Sloppy Joes

If you have leftovers (which may be hard to believe!), storing them is simple. Place any remaining beef mixture in an airtight container and store it in the refrigerator for up to 3 days. The mixture can also be kept in the freezer for about 3 months. To reheat, simply thaw if frozen and warm it in a skillet or microwave until heated through.

As for the buns, it’s best to store them separately. Keep them in a sealed bag at room temperature, and they should stay fresh for a few days.

Tips and Mistakes to Avoid

Don’t rush the onions: Spend the proper amount of time caramelizing the onions. This adds incredible flavor to the dish.
Avoid overcooking the beef: Ground beef should not be overcooked, or it may become dry. Just make sure it’s fully browned.
Taste as you go: Adjust the seasoning to your liking. A touch more salt or a splash of soy sauce can make a big difference.
Choose the right buns: A sturdy hamburger bun works best to hold all the juicy goodness without falling apart.

Variations

You can easily adjust this recipe to suit your taste preferences, minus the richness of the original flavor:

Add Veggies: Incorporate diced bell peppers or mushrooms for added nutrition and flavor.
Spicy Version: Toss in some diced jalapeños or a sprinkle of red pepper flakes for a kick.
Different Cheeses: Swap the Swiss cheese for provolone, cheddar, or even blue cheese for a different flavor profile.
Use Different Meats: Ground turkey or chicken can be used as a lighter option without sacrificing taste.

FAQs
