Tomato paste substitutes

Tomato paste is highly concentrated cooked tomatoes reduced to a thick, nearly dry consistency. It contributes deep umami, mild acidity, and body to dishes without adding significant liquid. Substituting requires accounting for both its concentrated tomato flavor and its thickening effect — most alternatives introduce extra water that can throw off a recipe's consistency and flavor balance.

Rank Substitute Ratio (replaces 1 cup Tomato paste) Notes
#1 Tomato purée 3 tbsp tomato purée reduced in the pan (or 3 tbsp tomato purée per 1 tbsp tomato paste, cooked down until thick) Tomato purée is the closest relative — same flavor profile, just with more water, so cook it in the pan for 3–5 minutes before adding other liquids to concentrate it; skipping the reduction step produces a noticeably thinner, less complex result.
#2 Canned crushed tomatoes 1/4 cup (60 ml) crushed tomatoes, strained and reduced, per 1 tbsp tomato paste Works in long-cooked braises and stews where the extra liquid has time to cook off; the flavor is slightly brighter and less caramelized than paste, and it adds visible tomato texture that may be unwanted in smooth sauces.
#3 Sun-dried tomato paste or sun-dried tomatoes in oil 1 tbsp sun-dried tomato paste, or 2–3 oil-packed sun-dried tomatoes blended smooth, per 1 tbsp tomato paste Delivers concentrated umami and a similar thick consistency; the flavor skews sweeter and more intensely fruity, which reads well in pasta sauces and braises but can be too assertive in recipes where tomato paste plays a supporting background role.
#4 Ketchup 1 tbsp ketchup per 1 tbsp tomato paste Works in a pinch in slow-cooked dishes where added sugar and vinegar will be diluted — visibly worse in any recipe that cooks briefly or where tomato flavor is prominent, because the sweetness and tang are noticeable; not recommended for savory braises or Mediterranean-style dishes.
#5 Tomato sauce (canned) 2 tbsp (30 ml) tomato sauce, reduced until thick, per 1 tbsp tomato paste More dilute than tomato purée and often pre-seasoned with salt or herbs; reduce it in the pan first and taste before adding other salt — suitable for long-cooked applications, mediocre for quick-cook recipes.
#6 Miso paste (white or yellow) plus tomato powder 1 tsp white or yellow miso paste + 1 tsp tomato powder per 1 tbsp tomato paste Covers the umami and thick-paste functions when no tomato product is available at all; the flavor is distinctly different — fermented and less bright — so it's a functional last resort in slow braises, not a flavor match; widely recommended by Serious Eats and America's Test Kitchen for umami-boosting, though less commonly cited specifically as a tomato paste stand-in.

When to be careful

Avoid substituting in recipes where tomato paste is a primary flavor driver and is not cooked into a larger sauce — such as pizza sauce that uses only 2–3 tbsp of paste thinned slightly, or Turkish-style dishes (e.g., mercimek çorbası) where paste is the sole tomato component. In these cases, the concentrated caramelized flavor of actual tomato paste is irreplaceable at the quantities used.

Why these substitutes work

Tomato paste gets its intensity from two processes: the Maillard reaction and caramelization that occur during extended reduction, which produce hundreds of flavor compounds not present in raw or lightly cooked tomatoes, and concentration of glutamates (especially glutamic acid) that provide strong umami. Its low moisture content (~75% less water than canned tomatoes) is why it thickens sauces without diluting them. Substitutes that haven't undergone the same reduction lack these Maillard-derived compounds, which is why stovetop reduction of any tomato substitute is the single most effective way to close the flavor gap.

Tomato paste is one of the harder pantry ingredients to substitute well because it does two jobs simultaneously: adding concentrated tomato flavor built through caramelization, and thickening a dish without diluting it. No substitute does both as efficiently, which is why every option in the table above involves either a reduction step or an accepted trade-off in flavor depth.

For most everyday cooking — braises, pasta sauces, soups — tomato purée reduced briefly in a hot pan is the strongest substitute. If you’re completely out of tomato products, the miso-plus-tomato-powder combination handles the umami function adequately in slow-cooked dishes, but don’t expect it to taste like tomatoes. Ketchup and canned tomato sauce are widely available fallbacks that hold up only when the recipe has enough other flavors and cooking time to absorb their shortcomings.

Frequently asked questions

Can I use fresh tomatoes instead of tomato paste?
Not reliably. You would need to cook down roughly 1 lb (450 g) of fresh tomatoes to get 2–3 tbsp of paste-equivalent concentrate, and the result still lacks the caramelized depth from industrial high-heat processing. Fresh tomatoes work better when swapped for canned tomatoes in a recipe, not for paste.
Does the substitution ratio change when tomato paste is used in small amounts (1–2 tsp)?
Yes — when a recipe calls for only 1–2 tsp of paste, its role is mostly umami and color. In that context, 1 tbsp of any canned tomato product stirred in without reduction is usually acceptable and won't noticeably affect consistency.
Can I freeze leftover tomato paste to avoid needing a substitute next time?
Yes. Spoon tomato paste in 1 tbsp portions onto a parchment-lined sheet, freeze until solid (about 2 hours), then transfer to a zip-lock bag. Frozen portions keep for 3 months and thaw in seconds in a hot pan — this is the standard recommendation from King Arthur Baking and Serious Eats.
