Cut the onion and carrots into small cubes
Prepare a medium pan and sauté them in olive oil for a few minutes until they change texture. Should take about 5 minutes or so at a low flame
Add the mince and stir often until the meat changes color and goes crumbly (see image in notes). Add the cumin as you’re stirring to really open the aroma and disperse it evenly throughout the entire dish. This step takes about 10 minutes
Add salt, red pepper, black pepper and (optionally) chili flakes about a minute before taking the pan off the stove
Preheat your oven to 350 F (180 C). In the meantime, peel and cut your zucchini into medium cubes
Place the zucchini on the bottom of a (traditionally) rectangular oven-safe container. Drizzle some olive oil and salt. Finally, add the contents of your pan on top, making sure the mince is evenly distributed
Bake for a total of 35 minutes - only open once at the 20-minute mark to stir
Finally, let’s prepare the topping. Mix ricotta, eggs, salt and baking powder. Make sure to put the last ingredient in right before the mixture goes in the oven so that it actually rises
Once the 35 minutes from step 7 are up, take the tray out of the oven, pour the ricotta mixture evenly on top and put it back in for another 15 minutes
