ADD SEASONING after cooking the ground beef and onion, you may need to drain any excess fat from the ground beef before incorporating the seasonings.

PRO TIP: Do not pour grease down the sink! Make a foil cup and pour excess grease into it for easy cleanup that won’t clog your plumbing.

What’s the difference between a Sloppy Joe and a Hamburger?

Burgers are traditionally a sandwich made with minced meat and dry seasonings, which is then shaped into round patties and fried or grilled.

Sloppy Joes are a sandwich also made with minced meat (usually beef)but then cooked with a tomato-based sauce and other spices.

Both are traditionally served on a hamburger bun.

It’s so easy to customize sloppy joes!

  • Spice dicing a fresh jalepeño and putting it in the slow cooker with everything else.
  • Add pinto beans or kidney beans to add protein and fiber.
  • More vegetables? Dice the red pepper and add it to the pan with the ground beef and onion.
  • Cheese or no cheese, it’s delicious! You can use a different variety like Gouda, Gruyere, or Havarti for a delicious cheesy twist.

Getting Ahead Sloppy Joes?

Yes, you can make these sloppy joes ahead of time. Follow the recipe as directed (without buns or cheese)so cool freeze the sauce in an airtight container for up to 3 months before thawing, heating and serving.
