Method
Place the toasted walnuts in a food processor and pulse until coarsely ground, resembling breadcrumbs. Remove and set aside in a bowl.
Working in batches, place the cremini mushrooms in the food processor and pulse until finely minced to resemble ground meat. Be careful not to over-process them into a paste.
Heat the olive oil in a large Dutch oven over medium-high heat (around 190°C/375°F). Add the minced mushrooms in an even layer. Sear undisturbed for 5 to 7 minutes to evaporate their water content and develop color. Stir occasionally until deeply browned and reduced in volume.
Reduce the heat to medium. Add the diced onion, carrot, celery, minced garlic, crushed fennel seeds, and ground walnuts to the pot. Sauté until the vegetables are completely softened and fragrant, about 8 to 10 minutes.
Create a small well in the center of the pot. Add the tomato paste and cook, stirring it into the mixture, for 3 to 4 minutes until it turns a deep rust color.
Pour in the dry red wine to deglaze the pan. Use a wooden spoon to scrape up any browned bits stuck to the bottom. Let the wine simmer until it has almost completely evaporated.
Stir in the crushed canned tomatoes, vegetable broth, balsamic vinegar, soy sauce, and Marmite. Bring the mixture to a gentle simmer (around 95°C/203°F). Reduce heat to low, partially cover, and let simmer gently for 1 hour, stirring occasionally.
Remove the pot from the heat. Taste and adjust the seasoning with salt and freshly ground black pepper as needed. Toss immediately with freshly cooked fettuccine or linguine to serve.
Chef's Notes
- The secret to the meaty texture lies in the deep searing of the mushrooms. Do not rush this step; evaporating their water and allowing them to brown heavily is critical for generating natural umami.
- Marmite and soy sauce provide naturally occurring glutamates. These stealth ingredients elevate the savory profile of this vegan ragu far beyond a standard tomato sauce, replicating the richness of meat without any animal products.
- Walnuts mimic the rich, fatty mouthfeel of ground pork or beef. Toasting them beforehand enhances their earthy, robust characteristics and prevents them from turning excessively mushy during the long simmer.
- This sauce benefits immensely from resting. Making it a day in advance allows the complex acids in the balsamic vinegar and wine to harmonize beautifully with the umami boosters.
Storage
Refrigerator: 5 days — Flavors deepen significantly over time, making this excellent for meal prep.
Freezer: 3 months — Freeze in airtight containers or heavy-duty freezer bags. Thaw overnight in the refrigerator.
Reheating: Reheat gently on the stovetop over medium-low heat until bubbling, adding a splash of water or vegetable broth if the sauce has thickened too much.
