Why does my tomato sauce taste bitter?

Bitterness often comes from burnt garlic or overcooked herbs. Sauté garlic just until fragrant (30 seconds) and add dried herbs after the tomato paste.

How can I make the sauce thicker?

Simmer it uncovered for an additional 10-15 minutes to evaporate more water, or stir in a tablespoon of tomato paste near the end.

Can I freeze this tomato sauce?

Absolutely, cool the sauce completely, transfer to freezer-safe bags or containers, and freeze for up to 3 months. Thaw overnight in the fridge.

What can I use instead of sugar to balance acidity?

Grate in half a carrot while simmering or add a pinch of baking soda—both neutralize excess acidity without adding sweetness.

Is it necessary to blanch the tomatoes?

Yes, blanching loosens the skins effortlessly, ensuring a smooth texture without bitter skin fragments. It also softens tomatoes for easy crushing.

SERVINGS

METHOD · 6 STEPS

prep · ~10 min
Blanch and crush the tomatoes.
1.Score a shallow 'X' on the bottom of each tomato with a knife.
2.Drop tomatoes into boiling water for 30-45 seconds until skins begin to peel.
3.Transfer immediately to ice water, then slip off the skins.
4.Crush the peeled tomatoes by hand in a large bowl, leaving some chunky texture.
TIPCrushing by hand gives better texture than a blender — you want a rustic, slightly chunky sauce, not a puree.
saute · ~6 min
Sauté the aromatics.
1.Heat olive oil in a large saucepan over medium heat until shimmering.
2.Add diced onion and cook until soft and translucent (4-5 min).
3.Stir in minced garlic and cook until fragrant (30-40 sec, do not brown).
TIPKeep the heat moderate — garlic burns quickly and turns bitter. Pull the pan off heat if it starts to brown.
saute · ~2 min
Bloom the tomato paste and herbs.
1.Add tomato paste to the pan and stir constantly for 1-2 minutes until it darkens slightly.
2.Sprinkle in dried oregano, dried basil, and red chili flakes, stirring to coat.
TIPCooking the tomato paste caramelizes its natural sugars and deepens the sauce's flavor dramatically.
simmer · ~35 min
Simmer the sauce to build flavor.
1.Pour in the hand-crushed tomatoes along with all their juices.
2.Add water, salt, and sugar. Stir everything together.
3.Bring to a gentle bubble, then reduce heat to low.
4.Simmer uncovered for 30-35 minutes, stirring occasionally, until thickened and reduced.
TIPA low, lazy simmer is key — rapid boiling toughens the tomato flavor. Look for small bubbles barely breaking the surface.
mix · ~1 min
Finish and season the sauce.
1.Remove sauce from heat. Taste and adjust salt as needed.
2.Add freshly ground black pepper and stir through.
3.Fold in half the fresh torn basil leaves.
garnish
Garnish with remaining fresh basil and serve hot over pasta, on pizza, or as a dipping sauce.
