Heat the olive oil in a large pan. Steam the onion and garlic cubes until soft. Add tomato paste and roast.
Then add the chopped tomatoes, rosemary and bay leaves. Bring everything to the boil, reduce the heat and boil down thickly for 25-30 minutes. If necessary, dilute with the tomato juice. Remove the herbs and season with salt and pepper.
Preheat the oven to 190 ° C fan oven.
Mix the spinach, ricotta, feta, parmesan, mint, pine nuts and eggs thoroughly. Season to taste with salt and pepper. Pour this mixture into the cannelloni with a teaspoon. Cover the bottom of a large, flat, coated baking dish with tomato sauce. Spread the cannelloni on top and cover with the remaining tomato sauce. All noodle parts should be covered, without liquid they will not become soft.
Cover with the mozzarella (so that no noodle can be seen if possible) and bake for about 30-40 minutes. The pasta should be soft (test with a skewer) and the cheese should be golden yellow.
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.
