Can I make French onion sloppy joes ahead of time?

Yes! This french onion sloppy joes recipe is perfect for prepping ahead. Make the filling up to 3 days in advance and store it in the fridge. Reheat on the stove and assemble just before serving for the best texture and flavor.

What’s the best cheese for French onion sloppy joes?

Provolone and gruyère are classic choices because they melt well and match the rich onion flavor. Swiss and mozzarella also work if you want a milder or more budget-friendly option.

Can I use a packet of onion soup mix instead of caramelizing onions?

You can, but you’ll lose the deep, sweet complexity that comes from slow-cooked onions. If you’re in a rush, use the mix and add sautéed onions for the best of both worlds.

How do I turn these into sliders for a party?

Spoon the beef mixture onto toasted slider buns or Hawaiian rolls. Top each with cheese and broil briefly until melted. These mini french onion sloppy joes are perfect for game days or casual gatherings.
