Spicy Tomato Spaghetti Recipe
Introduction
This spicy tomato spaghetti is a simple and satisfying dish that brings a delightful kick to classic pasta. With a rich, garlicky tomato sauce and a touch of heat from dried chilli, it’s perfect for a quick weeknight dinner that tastes like it took hours to make.

Ingredients
- 3 tbsp olive oil
- 4 garlic cloves, finely sliced
- 1 dried red chilli or a large pinch of red chilli flakes (optional)
- ½ tsp caster sugar
- 1 tbsp red wine vinegar
- 2 x 400g cans chopped tomatoes or passata
- 1 tsp dried oregano
- 400g spaghetti
- 15g parmesan, finely grated, to serve
Instructions
- Step 1: Heat 2 tablespoons of olive oil in a shallow pan over medium heat. Add the sliced garlic and dried chilli (if using), and gently sizzle for about 2 minutes until fragrant but not browned.
- Step 2: Sprinkle in the caster sugar and splash in the red wine vinegar. Then add the chopped tomatoes or passata along with the dried oregano. Season with salt and simmer the sauce gently for 25-30 minutes, stirring occasionally until it thickens.
- Step 3: Meanwhile, cook the spaghetti according to the package instructions until al dente. Drain the pasta and return it to the pan.
- Step 4: Pour the tomato sauce over the spaghetti, remove the whole dried chilli, and toss everything together over low heat for 1 to 2 minutes to combine the flavors.
- Step 5: Turn off the heat and stir in the remaining 1 tablespoon of olive oil and the grated parmesan cheese, if using, before serving.
Tips & Variations
- For a milder version, remove the seeds from the dried chilli before cooking or omit it entirely.
- Add fresh basil or parsley just before serving for extra freshness.
- Use fresh cherry tomatoes instead of canned for a brighter sauce in summer.
- If you prefer a creamier sauce, stir in a splash of cream or a spoonful of mascarpone at the end.
Storage
Store any leftover sauce in an airtight container in the fridge for up to two days, or freeze it for up to three months. Let the sauce cool completely before freezing. Reheat gently on the stove or in the microwave, adding a splash of water if it’s too thick. Cooked spaghetti is best freshly made but can be refrigerated for up to one day.

FAQs
Can I use fresh chillies instead of dried chilli?
Yes, fresh chillies can be used but adjust the quantity according to your heat preference. Add them early in the cooking to mellow or towards the end for more sharpness.
Is there a substitute for red wine vinegar?
If you don’t have red wine vinegar, you can use white wine vinegar or apple cider vinegar as alternatives. Use the same amount for a balanced tang.
