Brown the beef with onion and green pepper, stir it into a quick tomato, ketchup and mustard sauce, and let the slow cooker do the rest. A few hours on LOW thickens the sauce and deepens the flavour, and the cooker keeps the filling warm while everyone builds their own sandwich.

## Ingredients

### Beef

- 1 tbsp vegetable oil
- 1 kg lean ground beef, about 90% lean, thawed
- 1 large onion, finely chopped
- 1 green bell pepper, finely chopped
- 3 cloves garlic, minced
### Sauce

- 1 can tomato sauce or passata, 398 ml / 14 oz
- 120 ml ketchup, 1/2 cup
- 2 tbsp tomato paste
- 2 tbsp brown sugar
- 1 tbsp Worcestershire sauce
- 1 tbsp yellow mustard
- 1 tbsp cider vinegar
- 1 tsp chili powder
- 1/2 tsp salt
- 1/2 tsp black pepper
- 8 hamburger buns, split and toasted
- dill pickle slices, coleslaw or sliced cheddar, for serving

## Equipment

- Slow cooker (4-6 litre)
- Large skillet
- Wooden spoon
- Instant-read thermometer

## Instructions

1. **Brown the beef.** Heat the oil in a large skillet over medium-high heat. Add the beef, onion and green pepper and cook for 8-10 minutes, breaking up the meat, until no pink remains and it reaches 71°C (160°F). Stir in the garlic for the last minute, then drain off the fat.
2. **Mix the sauce.** Stir the tomato sauce, ketchup, tomato paste, brown sugar, Worcestershire sauce, mustard, vinegar, chili powder, salt and pepper together in the slow cooker.
3. **Slow cook.** Add the browned beef and stir to coat. Cover and cook on LOW for 4-5 hours or on HIGH for 2-3 hours, stirring once or twice if you are home, until the sauce is thick and glossy.
4. **Thicken if needed.** If the filling looks loose, take the lid off and cook on HIGH for 20-30 minutes more. Taste and add a little more salt, sugar or vinegar to suit.
5. **Serve.** Turn the slow cooker to WARM. Spoon the filling onto the toasted buns and add pickles, coleslaw or cheddar if you like.

## Tips

- Always brown the beef first. Raw ground beef clumps in a slow cooker, releases a lot of fat into the sauce and takes too long to heat up.
- Toast the buns so the sauce doesn't soak straight through them.
- For a party, keep the filling on WARM for up to 2 hours, stirring now and then, and set the buns and toppings beside it.
- Finely chopped onion and pepper melt into the sauce, which suits picky eaters.

## Variations

- Turkey sloppy joes: use ground turkey and brown it until it reaches 74°C (165°F).
- Stretch it: stir in a 540 ml / 19 oz can of rinsed lentils or kidney beans with the beef to serve 10.
- Smoky and spicy: swap the chili powder for 1 tsp smoked paprika and 1 finely chopped chipotle pepper in adobo.

## Storage

- Fridge: Refrigerate the filling within 2 hours in an airtight container for up to 4 days. Store the buns separately.
- Freezer: Freeze the cooled filling for up to 3 months. Thaw overnight in the fridge.
- Reheat: Reheat in a covered pan over medium heat, stirring and adding a splash of water if it is thick, or in the microwave, until it reaches 74°C (165°F). Do not reheat it in the slow cooker; once hot, you can hold it in the slow cooker on WARM.

## Frequently asked questions

### Do you have to brown ground beef before putting it in the slow cooker?

Yes. Browning the beef first lets you drain the fat, gives the sauce more flavour and stops the meat cooking into one dense block. Cook it until it reaches 71°C (160°F) with no pink remaining, drain it, then add it to the slow cooker.

### How long do sloppy joes take in the slow cooker?

Once the beef is browned, slow cooker sloppy joes take 4-5 hours on LOW or 2-3 hours on HIGH. The time is mostly for the sauce to thicken and the flavours to blend.

### How do I thicken watery sloppy joes?

Take the lid off and cook on HIGH for 20-30 minutes so the extra liquid can evaporate. Stirring in an extra 1-2 tablespoons of tomato paste also helps.

### Can I freeze sloppy joe filling?

Yes. Cool the filling, then freeze it in airtight containers or freezer bags for up to 3 months. Thaw it overnight in the fridge and reheat it on the stove or in the microwave until it reaches 74°C (165°F).
