What Goes Into Lamb Ragu

A rich, spicy pasta sauce like this Lamb Ragu is all about layering flavors. From the aromatic base to the slow-cooked lamb and silky pasta, every ingredient has its moment to shine.
- Lamb Steaks: Diced into hearty chunks, lamb brings a deep, savory richness that becomes meltingly tender as it simmers.
- Passata: Smooth, slow-cooked Italian tomato puree that forms the rich backbone of the sauce.
- Crushed Red Chilli Flakes: The source of this ragu’s heat, adding a bold, lingering spice that cuts through the richness.
- Pappardelle: Wide, flat pasta ribbons that perfectly cradle the thick, meaty ragu.
Note: Please see recipe card at the bottom for a full list of ingredients with measurements.
How To Make Lamb Ragu

- Sauté Aromatics: Heat the oil in a large skillet over medium high. Add the onion and carrot; cook until the onion is translucent, about 5 minutes. Stir in the garlic and cook for 30 seconds until fragrant.

- Brown the Lamb: Add the lamb and sear until well browned on all sides. Add the chopped tomatoes, then sprinkle in the oregano, thyme, and crushed red chilli flakes; stir for 1 minute to bloom that fiery heat.

- Build the Sauce: Pour in the passata (or marinara) and add the tomato paste. Bring to a gentle boil, then reduce the heat to low and let the ragu settle into a steady simmer.

- Simmer and Season: Stir in the wine, stock, and a pinch of salt. Cover and simmer, stirring occasionally; when the lamb begins to soften, add the water and continue cooking until tender.

- Cook the Pasta: While the ragu simmers, cook the pappardelle according to packet directions until al dente. Drain well, then toss with 2 ladles of the ragu to coat the noodles.

- Finish and Serve: Taste and adjust salt and heat, adding a pinch more chilli flakes if you want extra fire. Plate the pasta, spoon over more lamb sauce, and finish with Parmesan.
Pair your Lamb Ragu on pappardelle with grilled bruschetta portobello mushrooms, whose smoky, juicy bite offers a satisfying vegetarian counterbalance to the rich sauce. Add cilantro lime cauliflower rice on the side for a light, citrusy lift that cuts through the heat of the chilli flakes. For a sweet finish, try chai apple muffins; their warm spice and tender crumb echo the ragu’s depth while providing a cozy, unexpected dessert. Or, for another hearty option, serve it alongside Greek Chicken and Potatoes for a Mediterranean-inspired feast.
