Steps

1. Slice 1/4 onion (50g) thinly.
   🕒 04:08
2. Slice 30g bell pepper thinly, seeds and all. 【Tip!】 If bell peppers are added at the beginning, their aroma will dissipate, so it's recommended to add them later.
   🕒 04:14
3. Slice 40g mushrooms. 【Tip!】 If you don't have mushrooms, you can substitute with maitake, shimeji, or king oyster mushrooms.
   🕒 04:40
4. Mince 1 clove garlic. 【Tip!】 If you dislike raw garlic, you can substitute with garlic powder.
   🕒 05:18
5. Slice 60g sausage diagonally and thinly. 【Tip!】 Slicing diagonally increases the surface area, making it easier for the sausage's umami to release.
   🕒 05:51
6. Heat 1 tsp oil in a frying pan. Once hot, add 60g sausage and stir-fry until browned. 【Tip!】 Since oil will render from the sausage, stir-fry with a small amount of oil initially. Adding garlic or other vegetables from the start will cause them to burn.
   🕒 08:33
7. Once the sausage is browned, add 1 clove garlic and 1/4 onion (50g), and stir-fry over medium heat.
   🕒 09:20
8. Add 40g mushrooms and sauté thoroughly.
   🕒 09:51
9. Add 3 tbsp ketchup and 1 tsp Worcestershire sauce, increase the heat, and reduce until the moisture from the ketchup evaporates. 【Tip!】 To remove the acidity from the ketchup and concentrate its umami and sweetness, sauté thoroughly until it thickens.
   🕒 10:04
10. Add 360ml water and bring to a boil.
    🕒 11:09
11. Add MSG(Ajinomoto) KK Consommé 2/3 tsp and mix well.
    🕒 11:26
12. Once boiling, add 100g 1.6mm pasta to the pan, twisting it in, and cook for 7 minutes.
    🕒 11:49
13. Just before the pasta is fully cooked, turn the heat to high and continue heating until the pasta has absorbed all the sauce and all moisture has evaporated. 【Tip!】 Napolitan pasta is a dish meant to be 'sautéed/fried', so evaporating all the moisture results in a fragrant and crispy finish.
    🕒 17:55
14. Add 10g butter, the pre-cut 30g bell pepper, and 2 tsp ketchup (for extra flavor).n【Tip!】 Adding extra ketchup replenishes the aroma lost during cooking and enhances the flavor.
    🕒 19:03
15. Using the butter's oil, gently sauté the entire pasta in the pan to create a fragrant browning. 【Tip!】 The final 'sautéing' is the essence of the ultimate Napolitan pasta, significantly boosting its aroma and richness.
    🕒 19:50
16. Plate the pasta, and if desired, sprinkle with Parmesan cheese to taste and black pepper to taste, then serve.
