Ingredients

  • 500 g free range / organic beef mince
  • 1 small yellow onion finely diced (70g)
  • 2 tbsp taco seasoning
  • 2/3 cup water 160 ml
  • 1/2 cup red bell pepper diced (74g)
  • 1 tin chopped tomatoes 400g
  • 1/2 cup sour cream 120g
  • 1 - 2 diced green jalapeño chilli optional (14g)
  • 1 cup cheddar cheese shredded (113g)

Taco seasoning (makes approx. 2.5 tbsp)

  • 1 tbsp chilli powder I used mild
  • 3/4 tsp paprika
  • 1 tsp cumin
  • 1/4 tsp garlic powder
  • 1/4 tsp dried onion powder
  • 1/4 tsp oregano
  • 3/4 tsp salt
  • 1/2 tsp black pepper

Optional garnish:

  • 2 medium spring onions / scallions (30g)
  • 10 black olives sliced (30g)
  • 6 cherry tomatoes diced or salsa (65g)
  • 2 tbsp chopped coriander (8g)
  • 1 avocado (200g)

Instructions

  • Preheat oven to 350 Fahrenheit / 180 Celsius.
  • Place the beef mince and onion in a non stick frying pan and fry for 4 - 5 minutes, breaking up meat, until cooked through. Drain and discard any excess fat.
  • Make the homemade taco seasoning by mixing everything together in a bowl. This makes slightly more (approximately 2.5 tbsp) than you need. Add 2 tbsp for this recipe and see if you like it a little hotter and option to add the rest.
  • Add the peppers, 2 tbsp of taco seasoning, tinned tomatoes and 2/3 cup of water. Bring to a boil then re-duce to a simmer and cook for about about 7 minutes until thickened, stirring occasionally.
  • Add the beef to a greased oven proof casserole dish or cast iron skillet. Mine was a 26 x 5cm round cast iron pan. Then layer the sour cream and spread with a spatula and top with shredded cheese.
  • Bake for 25 - 30 minutes uncovered or until the cheese is melted.
  • Allow to cool slightly and top with optional garnishes of choice
