Peel onion and garlic and chop finely. Sauté in hot oil. Stir in tomatoes, 1/8 l water, tomato paste and stock, bring to the boil. Spice up. Mix the sauce and pasta. Spread in a large greased casserole dish (or 4 small ones).
Wash and pat dry the fish fillet and marinate with lemon juice for about 5 minutes. Dab again, season with salt and pepper and place on top of the pasta.
Wash and chop parsley. Melt the butter. Mix with breadcrumbs, marjoram, parsley and cheese. Season with salt and pepper.
Spread the crumbs on the fish. Spread a few chunks of butter on the pasta that are not covered with the fish.
Bake in the preheated oven (electric stove: 200 ° C / convection: 175 ° C / gas: level 3) for about 25 minutes.
Tip:
You can also mix other cooked pasta with tomato sauce.
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.
