In 20 minutes, serve Spicy Spaghetti with a rich, flavorful tomato sauce made from crushed tomatoes, red pepper flakes, and garlic. This Italian-style dish is perfect for a quick, satisfying dinner. Simply cook the spaghetti, toss it in the delicious, spicy tomato sauce, and enjoy!

Everyone has a secret to making a quick meal, and this spicy spaghetti recipe is mine. You only need a few staple ingredients to toss together, and your dinner is ready effortlessly(like this Instant Pot spicy penne pasta recipe)!
This recipe is inspired by the classic Italian arrabbita sauce, with a mild tweak to make it even more accessible. While the classic recipe calls for fresh red chili peppers, we use pantry-staple red pepper flakes instead. It tastes fabulous, and you won’t miss the original version’s flavor and taste(have you tried this chicken curry pasta)!
I prefer this simple recipe for chilly, ultimate cold-weather nights, where I don’t need a trip to my grocery stores and do not need long hours for prepping.
This spicy spaghetti is saucy, with bold tomato flavors. The al dente pasta holds the rich, creamy sauce beautifully. If you’re worried about the heat, you can easily adjust it to your preference(we can see it all in detail below).

Ingredients
- Olive oil: I used extra-virgin olive oil, perfect for bringing the classic flavors.
- Garlic: Fresh garlic is a must for the best taste.

- Crushed tomatoes: They are the easiest option. You can also use fresh tomatoes(see FAQ for instructions).
- Oregano & Parsley: I used dried oregano since it’s winter and snowy, and I couldn’t go shopping. Feel free to use it if you have fresh ones.
- Spaghetti: You can use whole-grain, protein-enriched spaghetti or any other type that you have at home.
How To Make Spicy Spaghetti
- Boil salted water in a large pot. Add spaghetti and cook until al dente, following the package instructions. Reserve ¼ cup of pasta water, then set it aside.
- In a large pan, heat olive oil over medium heat. Add minced garlic and red chili flakes. Sauté for one minute until fragrant, being careful not to burn the garlic.
- Pour crushed tomatoes into the pan and stir well. Add dried oregano and salt. Let the sauce simmer for 10–15 minutes, stirring occasionally, until it thickens slightly.
- Add the cooked spaghetti and the reserved pasta water to the sauce. Toss everything together to coat the spaghetti evenly. Plate the pasta, garnish with dried parsley, and enjoy.
♨️How To Adjust The Heat Level
This spicy spaghetti has a noticeable kick of heat. However, you can easily make it with mild or moderate heat to suit your taste.
If you have freshly chopped chili peppers like jalapeno or serrano, you can use them instead. Just adjust the quantity based on your heat tolerance.
For milder heat, start with a small amount of red pepper flakes and adjust as needed.
For extra heat, increase the red pepper flakes and add a pinch of cayenne pepper.
The Leftovers
Use the leftovers as the main dish or toss them into soup or salad.
- You can store leftover spaghetti in the refrigerator for about three days or in the freezer for up to two months.
- To thaw, place frozen spaghetti in the refrigerator overnight or use the microwave to thaw it quickly.
- Reheat the spaghetti gently on the stovetop or in the microwave. Sprinkle a little water over the pasta to prevent it from drying out. Stir occasionally to ensure it heats evenly without breaking. For best results, use medium heat to preserve the al dente texture of the pasta.
Pro Tips For Best Results
Drizzle some olive oil over the spaghetti just before serving. This final touch of olive oil and garnish enhances the flavor and gives the dish a beautiful finish.
