A rich and hearty ragu that combines tender beef chunks with earthy mushrooms and protein-packed lentils. This slow-cooked sauce is deeply savory and perfect for a comforting family dinner served over pasta or mash.
Place the dried porcini mushrooms in a small heatproof bowl and cover with 250ml of boiling water. Allow them to soak for 20–30 minutes until softened.
Meanwhile, heat 2 tablespoons of the rapeseed oil in a large flameproof casserole dish over medium-high heat. Once the oil is shimmering, add the beef chunks and sear for 10–12 minutes, turning occasionally, until deeply browned on all sides. Transfer the beef to a separate bowl using a slotted spoon.
Add another tablespoon of oil to the same pan. Sauté the chopped chestnut mushrooms for 8–10 minutes until they are well-browned and their moisture has evaporated. Transfer them to the bowl with the beef.
Add the final tablespoon of oil to the pan and reduce the heat to medium-low. Cook the finely chopped onions, carrots, and celery with a pinch of salt for 10–12 minutes, stirring occasionally, until the vegetables are soft and translucent.
Drain the rehydrated porcini mushrooms (you can reserve the soaking liquid for extra depth, straining it through a fine sieve first) and roughly chop them. Add the porcini, garlic, and tomato purée to the pan with the vegetables. Cook for 3–4 minutes to mellow the acidity of the tomato.
Stir in the lentils, beef stock, the browned beef and chestnut mushrooms, butter, and the parmesan rind. Bring the mixture to a gentle simmer, then cover with a tight-fitting lid.
Simmer over very low heat for 3 hours, or until the beef is incredibly tender and falls apart when pressed with a spoon. Alternatively, cook in a pressure cooker on high for 1 hour. Remove the parmesan rind and season to taste with salt and pepper before serving.
For an even richer flavor, replace 100ml of the beef stock with a splash of dry red wine. If the sauce is too thin after 3 hours, simmer uncovered for the last 15 minutes to reduce. This ragu tastes even better the next day and can be frozen for up to three months.
