I swear this Slowly Braised Lamb Ragu is the kind of rich, meaty sauce that makes every strand of pappardelle feel like the main event. One pot turns humble lamb shoulder, tomatoes, and herbs into pure Italian comfort food magic.

Jump to Recipe

I’m completely obsessed with this slowly braised lamb ragu because it’s big, rich, and unapologetically meaty in the best way. The lamb shoulder turns insanely tender, the sauce gets deep and savory, and every bite feels like something I’d happily order at a tiny Italian spot with zero regrets.

I love it tangled with pappardelle, spooned over gnocchi, or piled onto polenta when I want dinner to feel extra serious. And yes, I want the leftovers just as much as the first bowl.

Maybe more. This is the kind of pasta sauce I think about long after dinner is done.

Lamb shoulder turns meltingly tender and gives the ragu its deep, cozy richness.
Olive oil helps brown everything up, which means bigger flavor from the start.
Flour adds a little body, so the sauce clings nicely to pasta.
Onion, carrots, and celery bring that sweet, savory base every good ragu needs.
Garlic makes it smell incredible and keeps the sauce from tasting flat.
Tomato paste adds bold, cooked-down tomato flavor without making things watery.
Red wine brings depth and a little tang that works so well with lamb.
Crushed tomatoes make the sauce hearty, saucy, and perfect for twirling.
Stock keeps everything juicy while the lamb slowly breaks down.
Milk or cream softens the acidity and makes the sauce feel extra lush.
Bay, rosemary, and thyme add earthy flavor without shouting over the lamb.
Red pepper flakes give a tiny kick, if you’re into that.
Plus, sugar can tame sharp tomatoes when they’re tasting a little too bright.
Parsley and cheese finish it fresh, salty, and honestly pretty irresistible.
Basically, pappardelle, gnocchi, or polenta turn this into total comfort food.

How to Make this

Print Recipe (No Advertisments)

1. Pat lamb shoulder chunks dry, season with salt and pepper and optionally dredge lightly in flour; heat 2 to 3 tablespoons olive oil in a heavy Dutch oven or skillet over medium high heat and brown the lamb in batches until deeply caramelized, then set aside.

2. Reduce heat to medium, add the chopped onion, diced carrots and celery and cook until softened and beginning to color, about 6 to 8 minutes; stir in the minced garlic and 2 tablespoons tomato paste and cook 1 to 2 minutes until fragrant.

3. Pour in 1 cup dry red wine to deglaze the pan, scraping up browned bits from the bottom; reduce the wine by about half, about 3 to 5 minutes.

4. Return the lamb to the pot and add 28 oz crushed tomatoes, 1 to 2 cups stock as needed to just cover or come about two thirds up the meat, 2 bay leaves, rosemary and thyme sprigs (or dried), 1/2 teaspoon red pepper flakes if using, and 1 teaspoon sugar if desired; stir to combine and bring to a gentle simmer.

5. Stovetop simmer method: cover partially and simmer gently for 2 1/2 to 3 hours until lamb is fork tender, adding more stock if it becomes too thick; oven method: cover and transfer to a preheated 325 F oven for 2 1/2 to 3 hours.

6. Slow cooker method: after step 4 transfer everything to a slow cooker and cook on low for 6 to 8 hours or on high for 3 to 4 hours until lamb is very tender.

7. Instant Pot method: use the Sauté steps for browning and vegetables directly in the pot, add liquids and aromatics, seal and cook on High Pressure for 45 to 60 minutes for large chunks, then allow a natural pressure release for 15 to 20 minutes; if sauce is too thin, use Sauté after pressure release to reduce.

8. Remove lamb pieces and shred with two forks, discarding any large bones, then return the shredded meat to the sauce; stir in 1/4 cup whole milk or heavy cream to round out the acidity and simmer gently for 10 to 15 minutes to meld flavors.

9. Taste and adjust seasoning with salt, pepper and more sugar if needed; skim excess fat if desired and remove bay leaves and herb stems.

10. Serve the lamb ragu tossed with pappardelle, gnocchi, polenta or your pasta of choice, garnish with chopped flat leaf parsley and plenty of grated Pecorino Romano or Parmesan.

FAQ

Can I use bone in or boneless lamb shoulder Which is better

Both work well Bone in adds extra flavor and richness during cooking while boneless is easier to shred Choose based on preference and availability

Do I need to dredge the lamb in flour

Dredging is optional It helps with browning and slightly thickens the sauce but you can skip it for a lighter sauce

Can I make this in a slow cooker or Instant Pot and do the flavors change

Yes For slow cooker brown lamb and aromatics then transfer to slow cooker and cook on low 6 to 8 hours For Instant Pot brown on Sear then cook on High pressure 45 to 60 minutes with a natural release Flavors deepen with longer, slower cooking

How do I know when the lamb is done

The lamb should be very tender and fall apart easily when tested with a fork Internal temperature for safety is 145 F but for shredding cooked low and slow until fork tender is ideal

How can I adjust the sauce consistency

Simmer uncovered to reduce and thicken Add up to 1 to 2 cups stock if sauce seems too thick or use a splash of milk or cream at the end for silkiness If too thin simmer longer or remove meat and reduce sauce separately

What should I serve with this ragu and how to finish it

Serve over pappardelle, gnocchi, polenta or your favorite pasta Finish with chopped parsley and grated Pecorino Romano or Parmesan A splash of good olive oil and extra cheese at the table elevate the dish

Slowly Braised Lamb Ragu {+ Slow Cooker & Instant Pot Directions} Recipe Substitutions and Variations

Lamb shoulder: substitute beef chuck or short ribs for similar richness; use pork shoulder for a slightly sweeter profile; for vegetarian option, use a mix of mushrooms and lentils for texture and umami.
Dry red wine: substitute dry white wine or extra stock plus 1 tablespoon red wine vinegar; for nonalcoholic option, use additional beef or vegetable stock with a splash of balsamic vinegar.
Crushed tomatoes: substitute tomato passata for a smoother sauce; use canned diced tomatoes pulsed briefly in a blender for a chunkier texture; fresh plum tomatoes, peeled and crushed, work when in season.
Whole milk or heavy cream: substitute half and half for lighter richness; stir in a spoonful of sour cream or crème fraiche off heat for tang and creaminess; for dairy free, use canned full fat coconut milk sparingly for richness.

Pro Tips

1. Brown the lamb well in batches so you get deep fond on the bottom of the pot; those caramelized bits are flavor gold when you deglaze with the red wine. Don’t crowd the pan or you’ll steam instead of brown.

2. Use a mix of liquid levels while braising: just cover the meat for the oven or stovetop, but keep a little extra stock nearby. It is easier to add a splash toward the end than to dilute an over-reduced sauce.

3. If you have time, make the ragu a day ahead and refrigerate it. The flavors mellow and knit together overnight, and the sauce often tastes even better the next day. Reheat gently and add the milk or cream at the last moment.

4. For extra silky texture, skim the sauce of any floating fat once cooled a bit, or spoon the fat off after chilling. If you want a richer mouthfeel without more fat, finish with the 1/4 cup milk or cream and a small knob of butter off heat.

5. Match the starch to the sauce weight: wide pappardelle or creamy polenta stand up to chunky shredded lamb, while smaller pastas or gnocchi are great if you prefer the sauce to coat each bite. Generously top with Pecorino and fresh parsley for brightness.
