Step 1

Heat oil in a large heavy-based flameproof casserole dish or non-stick saucepan over medium-high heat (see note). Add onion, carrot and celery. Cook, stirring occasionally, for 3 minutes or until onion starts to soften. Add bacon. Cook for 3 minutes or until golden. Add garlic. Stir to combine.

Add spaghetti. Reduce heat to medium. Simmer, uncovered, for 15 minutes or until spaghetti is tender and sauce has thickened, stirring mixture every 5 minutes.

Step 3

Remove pot from heat. Remove and discard thyme sprigs. Add parsley. Season with salt and pepper. Stir to combine. Serve topped with extra chopped parsley and parmesan.
