Equipment

Ingredients

  • 150 g rice (white or brown)
  • 500 g minced beef
  • 2 onions
  • 2 garlic cloves
  • 1 (400 g) tin of tomato passata
  • 400 ml beef stock
  • 1 teaspoon parsley
  • 1 teaspoon basil
  • 1 teaspoon dried oregano
  • 1 teaspoon paprika
  • ½ teaspoon salt
  • ¼ teaspoon pepper

Instructions

  • Start by browning your mince in a pan. Then, transfer the mince to the slow cooker.
  • Finely chop the onion and garlic, and saute in the same pan until it’s soft and translucent, about 4-5 minutes.
  • Add the onions to the slow cooker, along with the beef stock, tomato passata, parsley, basil, oregano, paprika, salt and pepper.
  • Place the lid and let the soup cook on high for 2-4 hours or on low for 4-6 hours.
  • Meanwhile, cook the rice in a pot following the cooking instructions on the pack. I use white rice, and cook the rice in plain water.
  • 30 minutes before serving, add the cooked rice to the slow cooker and give it a stir.
  • Serve the soup piping hot, with the optional side of crusty bread.

Notes

  • Always precook the rice before adding it to the slow cooker. This means that you can use leftover rice for this recipe.
  • You can substitute quinoa, bulgur or any other grain for the rice if you prefer.
  • If you’re pressed for time, you can skip the step of sauteing the onions and browning the meat, and simply dump it all in the slow cooker. I prefer to add these steps as I find it gives the soup a better flavour, but they are technically optional.
  • Use peppers of any colour. I love to mix colours as I think it looks nice, but you can use whatever you have at hand or whatever your family prefers.
  • If you don’t have all the herbs, you can replace the parsley, basil and oregano with 3 tsp Italian seasoning.

Leftovers

Leftover stuffed pepper soup can be stored in an airtight container in the fridge for up to 3 days. You can also freeze the leftovers for up to 3 months. Thaw frozen soup in the fridge overnight, then reheat it in the microwave until piping hot before serving.
The rice tends to absorb a lot of the liquid from the soup. Your leftovers might therefore look more like stew than soup. If you want to bring it back to a more liquid consistency, you can add some water or beef stock while reheating the soup.
