Add 1/2 tbsp vegetable oil into your Dutch oven or another large pot.
Add 400 g minced meat to brown. Once almost browned, add 1 tsp salt, 1/2 tsp white pepper and 2 tbsp oregano.
Add tomato sauce to browned meat and stir. Let cook together for about ten minutes.
Stir 200 g mascarpone into the bolognese sauce, make sure it is stirred throughout the sauce.
Break 150 g lasagna sheets in three pieces per sheet, do not worry if they break into smaller pieces. The broken lasagna is the perfect way to use up those broken sheets at the bottom of your package.
Stick the lasagna sheets into the sauce and gently push down.
Add a lid to your Dutch oven and let the lasagna cook for fifteen to twenty minutes. Check the sheets are soft but not cooked all the way.
Cut 200 g fresh mozarella into thin slices and add on top of your lasagna.
Shred 100 g cheddar cheese and add on top of the lasagna.
Add the lid again and let cook for another five minutes until the cheese has melted.
If you want to create a bubbly surface to your lasagna, place under grill in your oven for a few minutes, without the lid.
