Step 1: Boil the Pasta

1. Bring a large pot of water to a boil. Add salt and a little oil.
2. Add the large tube pasta and boil until it is just cooked but still firm. Do not make it too soft because the pasta will be stuffed and baked later.
3. Drain the pasta and let it cool slightly. Handle it gently so the pasta pieces do not break.

Step 2: Prepare the Minced Meat Filling

1. Heat oil in a pan. Add chopped onion and cook until soft and light golden.
2. Add ginger garlic paste and cook for about one minute until fragrant.
3. Now add the minced meat and cook until it changes color. Break the meat with a spoon while cooking so there are no big chunks.
4. Add chopped or blended tomatoes, tomato paste, red chili powder, paprika, turmeric, coriander powder, cumin powder, black pepper, oregano, and salt.
5. Cook everything together until the meat is fully cooked and the mixture becomes thick. The filling should not be watery because it needs to stay inside the pasta.
6. Add ketchup or pasta sauce for a richer lasagna-style flavor. Mix well and cook for a few more minutes.
7. Turn off the heat and let the filling cool slightly before stuffing the pasta.

Step 3: Make the White Sauce

1. In a saucepan, melt butter on low heat.
2. Add plain flour and stir continuously for 1 to 2 minutes. Do not let the flour turn brown.
3. Slowly add milk while whisking so the sauce stays smooth and lump-free.
4. Add cream, salt, black pepper, chili flakes, oregano, and chicken powder if using.
5. Cook on low heat until the sauce becomes creamy and slightly thick.
6. You can also add a little cheese to the sauce for extra creaminess. Mix until smooth.
7. The white sauce should be creamy but still pourable. If it becomes too thick, add a little more milk.

Step 4: Stuff the Pasta

1. Take each piece of boiled pasta and fill it with the prepared minced meat filling.
2. You can use a small spoon or a piping bag to make this easier.
3. Fill the pasta gently and do not press too hard, otherwise the pasta may break.
4. Arrange the stuffed pasta pieces in a baking dish. You can place them standing upright or lying flat, depending on your pasta shape and baking dish.

Step 5: Layer with White Sauce

1. Spread some white sauce at the bottom of the baking dish.
2. Place the stuffed pasta on top of the sauce.
3. Pour more white sauce over the stuffed pasta and spread it gently so the pasta is covered.
4. This white sauce layer keeps the pasta creamy and prevents it from drying out in the oven.

Step 6: Add Cheese on Top

1. Sprinkle mixed shredded cheese generously over the top.
2. Use mozzarella for a soft melted texture and cheddar for a stronger cheesy flavor.
3. Sprinkle oregano and chili flakes on top if you like extra flavor.

Step 7: Bake Until Golden and Bubbly

1. Preheat the oven to 180°C.
2. Bake the stuffed pasta for 20 to 25 minutes, or until the cheese melts and the top becomes lightly golden.
3. If you want a more golden top, broil it for 2 to 3 minutes at the end. Keep an eye on it so the cheese does not burn.
4. Once baked, let it rest for 5 minutes before serving.
