Steps
Before you start
- Have all ingredients measured and ready before you start cooking
- Toast the walnuts briefly if they're not already roasted; this releases their oils
- Use good-quality canned tomatoes or fresh ripe tomatoes in season
Toast the walnuts
- Heat the small skillet over medium heat.
- Add the chopped walnuts and toast, stirring frequently, for 3–4 minutes until fragrant and slightly darkened.
- Transfer to a plate and set aside.
- This deepens their flavor and prevents them from becoming soggy in the sauce.

Ready when: Walnuts are fragrant and lightly darkened
Tip: Don't skip toasting—it makes a noticeable difference in the final flavor
Sauté the onion and garlic
- In the large pot, heat the olive oil over medium heat.
- Add the diced onion and cook, stirring occasionally, for 5–6 minutes until soft and translucent.
- Add the minced garlic and cook for another 1–2 minutes, stirring constantly, until fragrant but not browned.

Ready when: Onion is translucent and soft; garlic is fragrant
Tip: Keep the heat at medium to avoid browning the garlic, which will turn bitter
Add tomato paste
- Stir in the tomato paste and cook, stirring constantly, for 2–3 minutes.
- This step allows the tomato paste to caramelize slightly, which deepens and concentrates the tomato flavor.

Ready when: Tomato paste darkens slightly and becomes fragrant
Tip: Don't skip this step; it prevents raw tomato-paste taste
Add crushed tomatoes
- Add the crushed canned tomatoes with their juices to the pot.
- Stir well to combine with the onion mixture.
- The sauce should bubble gently at the edges.

Ready when: Tomatoes are fully incorporated and mixture is bubbling gently
Build the flavor base
- Stir in the sumac, pomegranate molasses, and allspice (if using).
- These ingredients are the heart of the sauce—the sumac provides a bright, tart flavor reminiscent of lemon, while the pomegranate molasses adds subtle sweetness and depth.
- Stir thoroughly so everything is evenly distributed.

Ready when: All spices are fully incorporated and no streaks of sumac remain
Tip: Sumac can clump slightly—break it up against the side of the pot with your spoon
Add the walnuts
- Stir in the toasted walnuts, reserving a small handful for garnish.
- The walnuts will soften slightly as they cook but retain their nutty character.

Ready when: Walnuts are evenly distributed throughout the sauce
Simmer the sauce
- Reduce the heat to medium-low and allow the sauce to simmer gently, stirring occasionally, for 20–25 minutes.
- The sauce should bubble very gently, never at a rolling boil.
- As it simmers, the flavors will meld, the liquid will reduce slightly, and the sauce will thicken.

Ready when: Sauce is slightly thickened, flavors are well-developed, and it coats the back of a spoon
Tip: Stir every 5–7 minutes to prevent sticking on the bottom
Season to taste
- Taste the sauce and season with kosher salt and freshly ground black pepper as needed.
- Start with ½ teaspoon salt and adjust from there, as the pomegranate molasses and sumac already provide tartness and depth.
- The sauce should taste bright, balanced between tart and sweet, with a warm spiced undertone.

Ready when: Sauce tastes well-balanced and flavorful
Tip: Taste it alongside pasta if you're making it, as the seasoning needs to stand up to the starch
Finish and serve
- Transfer the sauce to a serving bowl or directly toss with cooked, drained pasta.
- Garnish with the reserved toasted walnuts and the fresh parsley.
- Drizzle with a little extra olive oil if desired for a festive finish.

Good to know
Tips
- Sumac can be found in Middle Eastern markets, specialty spice shops, or online; it's worth buying in small quantities as it's aromatic and loses potency over time, so store it in an airtight container away from light.
- This sauce pairs beautifully with short pasta shapes like penne or rigatoni that trap the sauce and nuts, but it's also wonderful with thinner pasta like spaghetti or vermicelli for a lighter presentation.
- Double the recipe easily for a crowd—it scales well and actually deepens in flavor if made a day ahead.
- For a more textured sauce, reserve 1/2 cup of the crushed tomatoes before adding them, and stir in near the end of cooking so you have some fresh tomato brightness.
Make ahead
This sauce improves with time. Make it up to 2 days ahead, cool completely, and refrigerate in an airtight container. The flavors will deepen overnight. Reheat gently on the stovetop over medium-low heat, stirring occasionally, adding a splash of water if needed to loosen it.
Storage & reheating
Room temperature: up to 2 hours. Refrigerator: up to 4 days in an airtight container. Freezer: up to 3 months in a freezer-safe container or bag (thaw overnight in the refrigerator and reheat gently on the stovetop).
Substitutions
- pomegranate molasses → Balsamic vinegar or red wine vinegar (use 1.5 tablespoons and add a pinch of sugar). This will be less sweet and slightly more wine-forward, but still delicious. Pomegranate molasses is readily available in Middle Eastern markets or online and is worth seeking out for authentic flavor.
- walnuts, roughly chopped → Pine nuts or coarsely chopped almonds. Pine nuts will give a more delicate, buttery note; almonds will be slightly sharper. Both work well with sumac.
- ground sumac → Finely grated zest of 2 lemons mixed with 1 teaspoon lemon juice. This adds brightness but lacks sumac's subtle fruity depth. Use this only if sumac is unavailable.
- canned whole tomatoes (28 oz/800g can) → 2.5 pounds fresh ripe tomatoes, chopped (increase cooking time to 40 minutes to reduce liquid). Fresh tomatoes work beautifully in season but require longer cooking. The sauce will be lighter and more summery.
