Definitely try this budget-friendly, delicious and hearty Mexican Casserole with savoury ground beef, rice and beans. Baked with cheese on top and served with your favourite Tex Mex toppings like chunky guacamole, sour cream, jalapenos and corn chips.



For the beef filling

1 tablespoon olive oil

1 smaller portion of pre-made savoury beef (about 1.5 cups)

1.5 tsp smoked paprika

1.5 tsp cumin

1 tsp dried oregano

1/2 tsp salt

1/2 tsp chilli flakes

1 cup frozen sweet corn

1 can black beans, drained (400 g/14 oz, about 1.5 cups)

1 can chopped tomatoes (400 ml/14 oz or about 1.5 cups)

2 tablespoons BBQ sauce

2 tablespoons chopped coriander/cilantro

For baking the casserole

3 cups cooked rice (1 cup uncooked long-grain white rice)

2 tablespoons BBQ sauce

1.25 cups grated cheddar, Tasty or other cheese

To serve

1/4 cup sour cream

1 avocado

6 cherry tomatoes

1/4 red onion

1/4 chopped cilantro

Juice of 1 lime

1 small garlic clove

A pinch of salt

Optional: Crushed corn chips for crunch.


  • Heat a heavy saucepan or pan over medium-high heat and add a splash of olive oil. Add the pre-made beef, paprika, cumin, oregano, salt and chilli flakes, and stir through.
  • Add the frozen corn (no need to thaw out), drained black beans and canned tomatoes, stir through and cook for 2 minutes or so. Then add the BBQ sauce and stir. Finish with fresh coriander. This mixture can be frozen or stored or you can continue making the casserole.
  • You will need 3 cups of cooked rice (1 cup uncooked). Add the beef filling and the rice to a casserole dish and combine. Flatten with a spatula and spread the extra BBQ sauce over the top. Sprinkle the grated cheese evenly. Bake in the 200 C / 400 F oven for 10-15 minutes, until the cheese melts and turns into a golden, brown crust.
  • In the meantime, combine guacamole ingredients and set aside. Serve it on top of the cooked casserole along with a dollop of sour cream and some crushed corn chips for extra crunch.


This dish serves between 4-5 people depending on the toppings or sides. I calculated the nutrition for 4 servings with chunky guacamole and sour cream, and this would be pretty substantial portions.
