Frequently Asked Questions

What is the difference between sloppy joes and sloppy janes?

The primary difference is the type of meat used. Traditional sloppy joes are made with ground beef, while sloppy janes are typically made with ground turkey or sometimes ground pork, offering a leaner alternative.

What can I add to sloppy joes to make them taste better?

To enhance the flavor, you can add ingredients like Worcestershire sauce for depth, a touch of brown sugar for sweetness, diced bell peppers or onions for texture, or a splash of vinegar for a tangy kick.

Is French onion dip and sour cream and onion dip the same thing?

No, they are different. French onion dip is traditionally made with a base of sour cream and mayonnaise, mixed with dehydrated onion soup mix or caramelized onions. Sour cream and onion dip is typically just sour cream mixed with dried onion flakes and other seasonings.

What is the best beef for sloppy joes?

Lean ground beef, such as 85/15 or 90/10, is the best choice for sloppy joes. It has enough fat to provide rich flavor but not so much that it makes the sauce greasy.

What’s a New Jersey style sloppy joe?

A New Jersey-style sloppy joe is completely different from the ground meat version. It is a cold deli sandwich made with three slices of rye bread, layered with one or two types of meat (like turkey, ham, or roast beef), Swiss cheese, coleslaw, and Russian dressing.

What makes sloppy joes better?

Toasting the buns is a simple step that makes a huge difference, as it prevents them from getting soggy. Using high-quality ground beef and allowing the sauce to simmer and thicken also helps develop a richer flavor.
