– 1 can (28 oz / 800 g) crushed tomatoes
– 2 tablespoons tomato paste
– 1/2 teaspoon sugar, optional, to balance tomato acidity
– 1 teaspoon dried oregano
– 1/2 teaspoon dried basil
– 1 teaspoon salt, or to taste
– 1/2 teaspoon freshly ground black pepper
– 1/2 cup (120 ml) reserved pasta water, as needed
– 1 tablespoon fresh lemon juice, optional
– 2 tablespoons fresh parsley or basil, chopped
– 1/3 cup (30 g) grated Parmesan cheese, optional
For Extra Flavor (Optional)

Instructions
Step 1: Boil the Spaghetti
Fill a large pot with water and bring it to a rolling boil. Add a generous pinch of salt, then add the spaghetti.
Cook according to the package directions until al dente, usually 8–11 minutes. Stir occasionally to prevent the strands from sticking together.
Before draining, reserve about 1 cup of pasta water. Drain the spaghetti without rinsing it.
Step 2: Sauté the Garlic and Onion
While the pasta cooks, heat the olive oil in a large skillet over medium heat.
Add the chopped onion and cook for 3–4 minutes until softened and translucent.
Add the minced garlic and red pepper flakes. Cook for 30–60 seconds, stirring continuously, until fragrant. Avoid burning the garlic, as it can make the sauce bitter.
Step 3: Add the Tomato Paste
Stir in the tomato paste and cook for 1–2 minutes. Let it darken slightly to develop a deeper, richer tomato flavor.
Add the smoked paprika and optional cayenne pepper. Stir well so the spices coat the onion and garlic evenly.
Step 4: Make the Spicy Tomato Sauce
Pour in the crushed tomatoes and stir thoroughly.
Add the oregano, dried basil, black pepper, and salt. If the tomatoes taste particularly acidic, add the optional sugar.
Bring the sauce to a gentle simmer, then reduce the heat to medium-low. Cook uncovered for 15–20 minutes, stirring occasionally, until thickened and flavorful.
If the sauce becomes too thick, add a splash of water or reserved pasta water.
Step 5: Adjust the Seasoning
Taste the sauce and adjust the salt, chili flakes, and black pepper according to your preference.
For extra heat, add more red pepper flakes or a small amount of chili oil. For a brighter flavor, stir in the optional lemon juice.
If you prefer a smoother sauce, use an immersion blender briefly before adding the pasta.
Step 6: Combine the Spaghetti and Sauce
Add the drained spaghetti directly to the skillet.
Toss thoroughly with tongs for 1–2 minutes, allowing the pasta to absorb the tomato sauce. Add reserved pasta water a little at a time until the sauce clings beautifully to every strand.
For a richer finish, stir in the optional butter.
Step 7: Garnish and Serve
Remove the skillet from the heat. Sprinkle with fresh parsley or basil and grated Parmesan cheese, if desired.
Serve immediately while hot, with extra chili flakes and Parmesan at the table.
Tips for the Best Spicy Tomato Spaghetti
1. Use good-quality tomatoes. Crushed canned tomatoes or ripe fresh tomatoes create the foundation of a delicious sauce.
2. Do not burn the garlic. Garlic cooks quickly and can turn bitter if left in hot oil too long.
3. Bloom the chili flakes. Briefly heating them in olive oil releases their flavor and distributes the heat throughout the sauce.
4. Simmer the sauce properly. Giving the tomatoes time to cook reduces excess acidity and deepens the flavor.
5. Save the pasta water. Its starch helps the sauce cling to the spaghetti and creates a silky consistency.
6. Cook the pasta al dente. Slightly firm spaghetti holds its texture better when tossed in the hot sauce.
7. Balance the heat. If the sauce is too spicy, add a little butter, extra tomato, or a small amount of cream.
8. Add herbs at the right time. Dried herbs work well during simmering, while fresh basil and parsley are best added near the end.
9. Avoid rinsing the pasta. The remaining surface starch helps the sauce adhere.
10. Serve immediately. Spaghetti tastes best when freshly tossed with the sauce.

Storage Instructions
Refrigeration: Store cooled spaghetti in an airtight container in the refrigerator for up to 3–4 days.
Freezing: Freeze the cooked spaghetti and sauce in airtight, freezer-safe containers for up to 2 months for best quality. The pasta may soften slightly after thawing.
Reheating on the Stove: Add the spaghetti to a skillet with 1–2 tablespoons of water. Warm over medium-low heat, stirring until heated through.
Reheating in the Microwave: Place a portion in a microwave-safe bowl, cover loosely, and heat in short intervals, stirring between intervals.
Make-Ahead Tip: Prepare the tomato sauce up to 3 days ahead and refrigerate it separately. Boil fresh spaghetti when ready to serve for the best texture.

Frequently Asked Questions (Q&A)
Q1: How do I make Spicy Tomato Spaghetti hotter?
Increase the red pepper flakes gradually, add fresh chopped chili, or stir in a little chili oil. Taste as you go to avoid making the sauce overwhelmingly hot.
Q2: Can I use fresh tomatoes instead of canned tomatoes?
Yes. Use approximately 2 pounds (900 g) of ripe tomatoes, chopped or grated. Simmer them longer until they break down and form a thick sauce.
Q3: Why does my tomato sauce taste too acidic?
Some tomatoes are naturally more acidic. Simmer the sauce longer and add a small pinch of sugar if needed. A little butter can also soften the sharpness.
Q4: Can I make this recipe without tomato paste?
Yes. You can omit the tomato paste, although the sauce may be less concentrated. Allow extra simmering time to thicken it.
Q5: Is Spicy Tomato Spaghetti vegetarian?
Yes. The basic recipe is vegetarian when made without meat or meat-based additions. Use vegetarian Parmesan if you want to keep the entire dish vegetarian.
Q6: Can I make it vegan?
Yes. Use olive oil instead of butter and omit the Parmesan or use a plant-based alternative.
Q7: Can I make the sauce ahead of time?
Yes. Prepare the sauce in advance, cool it promptly, and refrigerate it in an airtight container for up to 3 days. Reheat it before tossing with freshly cooked spaghetti.
Q8: What can I use instead of spaghetti?
Penne, linguine, fettuccine, rigatoni, or gluten-free pasta can all work well. Adjust the cooking time according to the package instructions.

Add grilled chicken, shrimp, lean ground beef, or cooked lentils. You can also choose a higher-protein pasta made from legumes.

Use plenty of boiling water, stir the pasta during the first minute of cooking, and toss it with the sauce immediately after draining.
Q12: Can I use jarred tomato sauce?
Yes. Use approximately 3 cups of tomato sauce and adjust the herbs, salt, and chili according to its existing seasoning. Simmer for 10–15 minutes to develop the flavor.

Add reserved pasta water a tablespoon at a time while tossing until the sauce reaches your preferred consistency.
