Prepare the vegetables

• Peel and finely dice the kohlrabi, carrots, celery sticks and onion.
• Mince the garlic cloves.

Sauté the vegetables

• Heat a splash of olive oil in a large pot over medium-high heat.
• Sauté the diced vegetables, garlic and fresh basil until they soften.

Brown the meat

• Add the ground beef and ground pork to the pot.
• Cook until fully browned, breaking the meat up with a spoon.

Simmer the meat sauce

• Pour in the skinless tomatoes, crushing them as you add them, then the tomato sauce.
• Season with salt, pepper, paprika and Italian herbs.
• Simmer uncovered on low heat.

Cook the ziti

• Boil a large pot of salted water.
• Cook the ziti pasta until a little less than al dente, then drain well.

Make the ricotta mix

• In a separate bowl, blend the ricotta and the egg together.

Coat the pasta

• Add the ricotta egg mix, a few spoons of the meat sauce and half of the Parmesan cheese directly to the cooked ziti.
• Mix everything together until the pasta is coated.

Assemble the dish

• Spread a thin layer of meat sauce in a greased baking pan.
• Layer the coated ziti, the remaining meat sauce, cubed mozzarella and shredded Parmesan in between.

Bake

• Top the last layer with the remaining mozzarella and Parmesan, then cover with foil.
• Bake at 190 °C, then remove the foil and bake until bubbly and golden brown.

Finish uncovered

• Remove the foil and continue baking until bubbly and golden brown.
