Cut bacon into 1cm strips, slice onion thinly, and slice garlic thinly.

Cut nanohana into 3–4cm pieces, place in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 1 minute 30 seconds.

Heat olive oil and garlic in a frying pan until fragrant, then add bacon and onion. Stir-fry over medium heat.

Once the onion softens, add water, milk, consomme powder, and butter. Mix well and bring to a boil.

Break spaghetti in half and add to the pan. Cover and cook according to the package instructions.
