The Best Braised Beef Short Ribs Recipe (Guinness Sauce)

If you’re craving a cozy, “lights low, big bowls out” kind of Sunday dinner, braised beef short ribs are the move. This is one of those dishes that feels like a special occasion. It needs no fancy skills. You just need a good pot or a slow cooker, a little patience, and trust in low heat. Short ribs are one of my favourite tougher cuts of meat because they want to be cooked slowly. The bones bring richness, the fat turns silky, and after a long braise the meat becomes that fall-off-tender magic you only get from time + moisture + a proper braising liquid. And the sauce? Dark, glossy, spoonable, and loaded with depth. And if slow cooker beef short ribs (aka beef short ribs crock pot) are more your thing, I’ve got a version for you that’s out of this world.

This dish leans hard into flavour-building with jammy onion, stout beer, and a touch of sweetness. We’re not tossing in extra vegetables like carrot and celery (classic mirepoix vibes) because we want the onions to take center stage. Less clutter, more focus, and a sauce that tastes like you actually tried (even if the oven did most of the work).

Why This Short Rib Cooking Method Works

A lot of braised beef short ribs recipes get one thing right: sear + braise. But the “why” matters, because that’s what helps you nail it every time.

• Hard sear at high temperature: This isn’t just for looks. Browning creates the flavour foundation and those sticky browned bits on the bottom of the pan are pure gold. That’s the base of the pot flavour you can’t fake later.
• Onions cooked low and slow: Instead of rushing them, we take them to that soft, dark, almost-jammy stage. That gives the sauce natural sweetness and body—no need to add a bunch of extra ingredients.
• Tomato paste + stout: Tomato paste adds savoury depth and colour. Guinness brings roastiness and complexity. Together, they make a sauce that tastes like it’s been simmering all day (because it basically has).
• Butter finish: This is the difference between “nice gravy” and “restaurant-style sauce.” It rounds out sharp edges and makes everything glossy.

Ingredient Notes That Actually Matter

You don’t need a million add-ons for these slow cooker beef short ribs, but the details count.

• Short ribs (bone-in if possible): Bone-in gives you better flavour in the braising liquid and helps protect the meat from drying out.
• Salt + black pepper: Use kosher salt if you’ve got it. The recipe calls for a bold seasoning (measured in tbsp), and that’s intentional—this is a big piece of meat and it needs it. If you’re nervous, start with a couple teaspoons per side and adjust later, but don’t go timid.
• Neutral oil (or olive oil): A tablespoon of oil helps you get that hard sear. Neutral oil is ideal, but olive oil works if that’s what you have.
• Onions + cloves garlic: Thinly sliced onions melt into the sauce. If you accidentally do diced onions, it’s not a deal-breaker—just expect a slightly different texture.
• Fresh herbs: Fresh thyme is the hero here. You could riff with rosemary, but the recipe sticks with thyme for a reason: it complements stout without taking over. Add your bay leaves (yes, even just one) and then discard them at the end.
• Beef stock / beef broth: Use what you’ve got—store-bought stock is totally fine. Just pick one you’d actually sip. (Technically, people say “beef broth” more often, but for this braised beef short ribs recipe you’re using beef stock for body.)

The Sear: Don’t Rush It

Here’s the trick that makes the whole dish taste expensive: dry the ribs. Pat them down with a paper towel, then season generously.

When you sear, go medium high heat until the pan is properly hot. If you crowd the pot, the ribs will steam, not brown—so work in batches. You want a deep crust and a pot that looks like it’s developing a little attitude.

Building The Sauce: Where The Magic Happens

Once the ribs are out, the onions go in and the heat drops to medium heat then down to low heat as they soften. Give them time. Stir now and then, scrape the base of the pot, and let them turn golden and jammy.

Then in goes garlic and tomato paste—stir it around until it smells sweet and roasted. When you pour in the Guinness, it should hiss and loosen all those browned bits. Let it simmer for a couple minutes to smooth out bitterness, then add beef stock, thyme, and bay.

Now the ribs go back in. You’re aiming for liquid about halfway up the meat so the top can braise and the bottom can soak. Pop on the lid, slide it into the oven, and let it go low and slow until the ribs are properly tender and the meat yields like it’s giving up.

Gravy Vibes For These Braised Beef Short Ribs:

When the ribs are done, pull them out and focus on the sauce. This is where you turn braising liquid into something you want to spoon over everything—whether you braised them in the oven or went the beef short ribs crock pot route and finished the juices on the stove.

First, skim excess fat—a ladle works great. If you’re making this the next day, the easiest move is to cool it, park it in the refrigerator, and lift the fat off once it solidifies. Then bring the sauce to a boil and let it reduce into a gentle simmer until the flavour tightens up.

To thicken, we’re using cornstarch instead of flour. It keeps the gravy clean and glossy. Finish with butter, then taste for salt.

And yes—this sauce has stout richness, but if you ever want to change the vibe, swapping the Guinness for cabernet sauvignon will push it toward a rich red wine sauce style. Same concept, different mood.

Slow Cooker Short Ribs

If you’d rather let the slow cooker do the heavy lifting, this version delivers the same fall-off-the-bone result with even less hands-on time.

How to make slow cooker short ribs:

Sear the short ribs first — don’t skip this step. Get a heavy pan ripping hot, pat the ribs dry, and sear on all sides until deeply browned. This builds the flavour base that carries through the entire braise. Transfer to your slow cooker.

Make the same Guinness sauce and pour it over the ribs. Cook on low for 8 hours or high for 4.5 hours. Either works — low and slow gives you a slightly more tender result if you have the time.

When done, transfer the ribs to a plate and let them rest. Skim the fat off the surface of the liquid in the slow cooker — there will be a fair amount and you want it gone before you make the sauce.

Pour the liquid into a pot over medium-high heat. Once it reaches a light simmer, whisk in 1 tbsp of flour and allow it to thicken into a glossy, spoonable sauce. Taste and adjust seasoning before serving.

Serve over mashed potatoes with the sauce spooned generously on top.

What to Serve With Short Ribs

Short ribs need something to soak up that Guinness sauce. These are the sides that earn a spot at the table:

Easy Mashed Potatoes — The classic pairing. Creamy mashed potatoes and braised short ribs with Guinness sauce spooned on top is one of those combinations that just makes sense. Non-negotiable in my opinion.

Candied Sweet Potatoes — A slightly sweeter, richer alternative to mashed potatoes that works beautifully against the deep savoury flavour of the Guinness sauce. Great for a holiday table alongside these ribs.

Roasted Pistachio Carrot Salad — A bright, slightly sweet side that cuts through the richness of the braise. The pistachios add crunch and the carrots bring colour to what is otherwise a pretty dark plate.

Greek Style Red Potato Salad — If you want something a little lighter and more acidic to balance the richness of the short ribs, this is the move. The tangy dressing does exactly what you need it to do.

Frequently Asked Questions

What are beef short ribs?
Short ribs are a cut of beef taken from the rib section — specifically the lower part where the ribs meet the belly. They’re a tougher cut with a lot of connective tissue and fat running through them, which is exactly what makes them perfect for braising. That collagen breaks down over long, slow cooking and turns into gelatin, giving you that silky, rich sauce and fall-off-the-bone texture.

Do I have to sear the short ribs before braising?
Yes — don’t skip it. Searing creates a deep brown crust through the Maillard reaction, which builds the flavour foundation for your entire braise. Without it, the dish tastes flat and the sauce lacks depth. Get your pan very hot, pat the ribs completely dry, and give them a proper sear on all sides before they go into the oven or slow cooker.

How long do you braise short ribs in the oven?
Low and slow is the move. At 325°F, bone-in short ribs typically need 2.5 to 3 hours. You’re looking for meat that pulls away from the bone easily and a sauce that has thickened and reduced. Start checking at the 2.5 hour mark.

Can you overcook short ribs?
It’s harder than you’d think, but yes — if you push them too far the meat can start to dry out and turn stringy rather than staying silky and tender. The window is generous though. Pull them when the meat is just starting to fall off the bone and the sauce has reduced to a glossy consistency.

Bone-in vs boneless short ribs — which is better?
Bone-in every time for braising. The bones add enormous richness and depth to the braising liquid as they cook, and the fat and marrow that release into the sauce are a big part of what makes it so good. Boneless work in a pinch but the sauce won’t have the same body.

Can I make short ribs ahead of time?
Yes — and they’re actually better the next day. The flavours deepen overnight and the fat solidifies on top of the sauce in the fridge, making it easy to skim off cleanly before reheating. Reheat gently covered in a low oven at 300°F or on the stovetop over low heat.

What do you do with the leftover braising liquid?
Reduce it. Pour it into a pot, bring to a simmer, and let it cook down until it’s glossy and thick enough to coat the back of a spoon. That’s your sauce. For the slow cooker version, whisk in 1 tbsp of flour once it reaches a simmer to help it thicken faster.

Can I freeze braised short ribs?
Absolutely. Cool completely, portion into airtight containers with some of the sauce, and freeze for up to 3 months. Thaw overnight in the fridge and reheat low and slow. They hold up beautifully.
