Corned beef is weird. Think about it. You’re taking a tough-as-nails brisket, brining it in salt and spices until it turns pink, and then simmering it for hours until it basically falls apart if you look at it too hard. It’s salty. It’s fatty. It’s got that distinct, spicy tang from peppercorns and mustard seeds. Because the flavor profile is so aggressive, figuring out what goes good with corned beef isn't just about grabbing whatever is in the pantry. You need sides that can stand up to that salt without making the whole meal feel like a sodium bomb.
Most people just toss in some cabbage and call it a day. That’s fine. It’s classic. But honestly? It can get a little boring if you do it every single year. If you want to actually enjoy the meal rather than just participating in a St. Patrick’s Day tradition because you feel like you have to, you’ve got to balance the richness.
The Traditional Heavy Hitters
Let's start with the basics because they're basics for a reason. Cabbage is the obvious partner. When you boil cabbage in the same pot as the beef, it soaks up all that rendered fat and pickling spice. It becomes sweet and buttery. But here’s the thing: soggy, gray cabbage is depressing. To keep it edible, don't put it in at the start. Throw it in during the last twenty minutes. You want it tender, not translucent.
Potatoes are the other non-negotiable. Red potatoes hold their shape best. If you use Russets, they tend to disintegrate into the broth, leaving you with a weird, starchy soup. Yukon Golds are a solid middle ground because they bring a natural creaminess that cuts through the saltiness of the meat.
Carrots and Parsnips: The Sweet Balance
You need sugar. Not white sugar, but the natural sweetness found in root vegetables. Carrots are the standard choice, but parsnips are the "pro move" here. Parsnips have an earthy, almost nutty sweetness that highlights the cloves and allspice usually found in corned beef seasoning packets. When they’re simmered in the pot liquor, they turn into little flavor sponges.
Some people swear by adding rutabaga or turnips. These are more of an acquired taste because they have a bitter edge. However, if your corned beef is particularly fatty, that bitterness provides a necessary counterpoint. It cleanses the palate.
Why Acidity Is the Secret to What Goes Good With Corned Beef
If you take away nothing else from this, remember that fat needs acid. Corned beef is incredibly rich. If you just eat meat and potatoes, your tongue gets coated in fat, and everything starts to taste the same after four bites.
This is why mustard is the goat of condiments here. Not the neon-yellow stuff you put on a ballpark hot dog. You want grainy, stone-ground mustard or a sharp Dijon. The vinegar in the mustard cuts right through the beef fat.
- Pickles: A side of sharp, garlicky dills.
- Sauerkraut: This is basically the bridge between cabbage and pure acid. If you aren't doing a boiled dinner, serving corned beef with a side of warm sauerkraut is elite.
- Pickled Onions: Specifically red onions pickled in apple cider vinegar. They add a crunch that the soft meat desperately needs.
Irish soda bread is another staple, but it serves a functional purpose. It’s dense. It’s dry. It’s meant to be slathered in salted Irish butter (like Kerrygold) and used to mop up the juices left on the plate. Without the bread, you're leaving the best part of the meal behind.
Elevating the Plate: Beyond the Pot
Maybe you’re tired of the "everything boiled in one pot" vibe. I get it. It can look a bit... beige.
Roasting your vegetables separately is a game changer. While the beef is simmering away on the stove, toss some Brussels sprouts or broccoli in olive oil and salt and roast them at 400°F until the edges are charred. That bit of caramelization adds a depth of flavor that boiling just can't touch.
Horseradish Is Not Optional
If you think you don't like horseradish, you might just be using the wrong kind. The creamy bottled stuff is okay, but freshly grated horseradish mixed with a little sour cream and lemon juice? That’s the real deal. It provides a nasal-clearing heat that isn't "spicy" like a chili pepper, but rather "bright." It wakes up the flavor of the beef.
In some parts of the UK and New England, people serve corned beef with a white sauce or a parsley sauce. It’s basically a simple béchamel with a ton of fresh parsley stirred in. It sounds weird, but the herbal notes of the parsley brighten up the heavy meat. It makes the whole dish feel less like "peasant food" and more like a Sunday roast.
The Day After: Leftovers and New Pairings
Honestly, the best part of making corned beef is the leftovers. The flavors actually settle and improve after a night in the fridge.
Corned Beef Hash
This is the gold standard. You chop the beef into tiny cubes, do the same with the leftover potatoes, and fry them in a cast-iron skillet until a crust forms. What goes good with corned beef hash? A runny poached egg. The yolk acts as a sauce, binding the crispy bits together.

The Reuben Factor
You can't talk about corned beef without mentioning the Reuben sandwich. It is a masterpiece of culinary engineering. You have the salty beef, the sour sauerkraut, the creamy Russian dressing, and the earthy rye bread. All of it is held together by melted Swiss cheese. If you’re making a Reuben, a side of potato chips or a simple slaw is all you need. The sandwich is the star.
Unexpected Sides That Actually Work
If you want to go off the beaten path, try a beet salad. Beets have that same earthiness as carrots but with a much bolder color and a slightly different sugar profile. A cold beet salad with goat cheese and walnuts provides a temperature and texture contrast that is genuinely refreshing alongside hot beef.
Glazed onions are another underrated gem. Take small pearl onions and braise them in a bit of beef stock and balsamic vinegar until they’re sticky and sweet. They act like little flavor bombs that bridge the gap between the savory meat and the starchy sides.
Mistakes to Avoid When Choosing Sides
Don't overcomplicate the seasoning of your sides. The beef is already seasoned with salt, peppercorns, mustard seeds, coriander, ginger, and maybe cinnamon or cloves. If you try to make a side dish with a complex spice profile—like a curry or a heavy garlic pasta—it’s going to clash.

Keep your sides simple. Let the vegetables taste like vegetables.
Also, watch the salt. Since the beef is cured in brine, it’s going to release a lot of salt into the cooking liquid. If you’re using that liquid to cook your cabbage and potatoes, you probably don't need to add any extra salt to the pot. Taste it first. You can always add salt later, but you can’t take it out once the potatoes have soaked it up.
Actionable Steps for the Perfect Meal
To pull this all together and move beyond the basic "boiled dinner" stereotypes, follow these specific steps:
- Timing is Everything: Start your beef first. It takes 45-50 minutes per pound. Only add your potatoes and carrots in the last 40 minutes of cooking. Cabbage goes in for the final 15-20 minutes.
- The Sear: If you want to level up, take the beef out of the liquid once it’s tender, rub the top with a bit of brown sugar and mustard, and pop it under the broiler for 5 minutes. It creates a crust that is incredible.
- The Sauce Trio: Don't just put the meat on the table. Serve three small bowls: a grainy mustard, a creamy horseradish sauce, and the cooking liquid (jus) on the side.
- The Bread Choice: Skip the dinner rolls. Buy or bake a loaf of rye or soda bread. The acidity in the rye flour is a natural match for the spices in the beef.
- Texture Contrast: If everything on the plate is soft, add a side of crunchy coleslaw or some crisp pickles. Your mouth will thank you for the variety.
Corned beef doesn't have to be a one-note meal. By focusing on acidity, natural sweetness, and a mix of textures, you turn a heavy, traditional dish into something balanced and actually sophisticated. Focus on the contrast between the salt of the meat and the brightness of your sides, and you'll never have a boring St. Paddy's dinner again.
