Heat the olive oil on a pan and add the diced onions.
Cook on a medium heat until they start to caramelize and turn brown, about 20 minutes.
Lay the frozen french fries on a large baking tray and cook as per the manufacturers instructions.
In another pan, cook the chorizo and ground beef together, drain any grease that may appear leaving only the meat.
Make the chipotle crema by adding the chipotle powder and cumin to the crema and stirring until combined. Set aside.
Once the french fries are cooked, adjust the oven temperature to 425 degrees F.
Center the french fries in the middle of the baking tray and arrange the chorizo all over the fries.
Top with the diced onion and both types of grated cheese.
Place back in the oven and bake for about 5 minutes and the cheese has fully melted.
Drizzle the crema over the melted cheese and sprinkle with the chopped cilantro.
Serve at once on the baking tray.
