Preheat oven to 200 °C / 400 °F (conventional) or 180 °C / 350 °F (convection).
Cook rice with about 4 times the amount of water and 1/4 teaspoon vegetable stock for 10 minutes. If using risotto, follow package instructions as it takes significantly longer.
Clean and wash chicory. Cut about 3 cm from the thick end and stalk. Peel off leaves one by one.
Add chicory leaves to a pot of water with 1 teaspoon vegetable stock, using enough water so the leaves float. Cover and simmer for 5 minutes, then drain.
Cut onion into cubes. Heat oil in a pan over medium heat. Sweat onion for about 3 minutes until lightly translucent, being careful not to burn. Add minced meat and cook for 8-10 minutes until done, stirring occasionally. Season with salt and pepper.
Cut tomato into slices and halve them. Grease a baking dish with butter.
Layer ingredients in the baking dish: chicory leaves, minced meat, rice, tomato slices, and roughly half the cheese. Repeat layers until all ingredients are used.
Top with a final layer of chicory leaves. Sprinkle breadcrumbs over the casserole, arrange remaining tomato slices on top, and sprinkle with remaining cheese. Optional: drizzle with balsamic vinegar.
Bake for 15 minutes at 200 °C / 400 °F (conventional) or 180 °C / 350 °F (convection) until the cheese turns golden brown.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
