Low-Carb Irish Beef Stew

I grew up thinking Irish stew had to be loaded with potatoes and served with thick slices of bread. That’s what my grandmother made every March, and honestly, I never questioned it. Then I started eating keto, and I figured my stew days were behind me.

Turns out, I was wrong. You can absolutely make a rich, hearty Irish beef stew without all those carbs. The secret is swapping the potatoes for low-carb root vegetables and letting that Guinness and beef broth do the heavy lifting. The flavors are just as good—maybe even better—and you won’t feel like you need a nap after finishing your bowl.

What Kind of Beef Should I Use?

For Irish beef stew, you’ll want to grab a tougher cut of beef that becomes tender and flavorful after slow cooking. Chuck roast is your best bet here – it has enough marbling to stay moist and literally falls apart after simmering in that Guinness broth. Stew meat from the grocery store also works great and saves you the trouble of cutting it yourself, just make sure the pieces are about 1 to 2 inches so they cook evenly. If you can’t find chuck, beef round or brisket will do the job too, though they might need a bit more cooking time to get that melt-in-your-mouth texture you’re after.

Options for Substitutions

This keto-friendly stew has some room for swaps, though a few ingredients are key to keeping it low-carb:

• Root vegetables: Since this is a keto recipe, stick with low-carb options like turnips, radishes, or cauliflower instead of potatoes or parsnips. Radishes are great because they soften and taste surprisingly potato-like when cooked.
• Guinness Stout: Regular Guinness has carbs, so look for a low-carb stout or dry stout if you can find one. Alternatively, use an extra cup of beef broth mixed with 1 tablespoon of balsamic vinegar and a splash of coffee for that dark, rich flavor.
• Beef: Chuck roast is traditional, but beef short ribs, brisket, or stew meat all work well. Just make sure it’s a tougher cut that benefits from slow cooking.
• Xanthan gum: This is your keto thickener, but if you don’t have it, try using a bit of glucomannan powder or just reduce the liquid more to naturally thicken the stew. Start with less than the recipe calls for – a little goes a long way.
• Broth: Beef broth is ideal here, but chicken or vegetable broth will work if that’s what you have on hand.
• Fresh herbs: If you don’t have fresh rosemary or thyme, use dried herbs instead – just cut the amount in half since dried herbs are more concentrated.

Watch Out for These Mistakes While Cooking

The biggest mistake you can make with beef stew is skipping the browning step or rushing through it – those caramelized bits on the bottom of the pot add serious depth of flavor, so make sure each piece of beef gets a nice sear before moving on.

Another common error is cutting your vegetables too small, which causes them to turn mushy during the long cooking time, so aim for chunks about 1-2 inches in size that can hold up through those 3 hours in the oven.

When it comes to thickening with xanthan gum, less is more – add it slowly while whisking constantly to avoid clumps, and remember that a little goes a long way since this stuff is powerful.

Finally, resist the urge to crank up the oven temperature to speed things along, as low and slow is what transforms tough beef into tender, fall-apart pieces that make this stew worth the wait.

What to Serve With Irish Beef Stew?

This hearty stew is pretty much a complete meal on its own, but I love serving it with some crusty bread or dinner rolls for soaking up all that rich, Guinness-infused gravy. If you’re keeping things keto, try it with some buttered cauliflower mash on the side or even some roasted cabbage wedges that pick up the flavors beautifully. A simple side salad with a tangy vinaigrette helps cut through the richness of the stew, or you could go traditional Irish style and serve it alongside some soda bread. For extra coziness on a cold night, I sometimes add a dollop of sour cream on top and sprinkle extra fresh parsley right before serving.

Storage Instructions

Store: This stew actually gets better after a day or two in the fridge! Keep it in an airtight container for up to 4 days. The flavors really meld together nicely, making it perfect for meal prep or enjoying as leftovers throughout the week.

Freeze: Irish beef stew freezes really well for up to 3 months. Let it cool completely, then portion it out into freezer-safe containers or bags. I like to freeze individual servings so I can grab just what I need for a quick dinner.

Reheat: Warm it up gently on the stovetop over medium-low heat, stirring occasionally until heated through. You can also microwave individual portions, but I find the stovetop method keeps the vegetables from getting mushy. Add a splash of broth if it seems too thick after reheating.

Ingredients

For the stew:

• 2.2 lb beef (cut into 1-inch chunks)
• 3 carrots
• 3 celery stalks (cut into 1/2-inch pieces)
• 2.2 lb root vegetables
• 1 large onion (diced into 1/2-inch pieces)
• 3 garlic cloves
• 1 tsp worcestershire sauce (I prefer Lea & Perrins for depth)
• 14.9 oz guinness stout
• 2.5 cups broth (I use Kettle & Fire beef bone broth)
• 1.5 tsp rosemary
• 1.5 tsp thyme
• 2 bay leaves
• 1.25 tsp salt
• 1 tsp black pepper
• 1/4 tsp xanthan gum (sifted to prevent clumping)
• 2 tbsp olive oil

For the garnish:

• fresh parsley

Step 1: Prepare Ingredients and Build Your Mise en Place

• 2.2 lb beef, cut into 1-inch chunks
• 3 carrots, cut into 1/2-inch pieces
• 3 celery stalks, cut into 1/2-inch pieces
• 1 large onion, diced into 1/2-inch pieces
• 3 garlic cloves, minced
• 1 tsp Worcestershire sauce
• 14.9 oz Guinness stout
• 2.5 cups beef broth
• 1.5 tsp rosemary
• 1.5 tsp thyme
• 2 bay leaves
• 1.25 tsp salt
• 1 tsp black pepper
• 1/4 tsp xanthan gum, sifted
• fresh parsley for garnish

Cut the beef into 1-inch chunks and set aside on a plate.

Dice the onion into 1/2-inch pieces, cut carrots and celery into 1/2-inch pieces, mince the garlic cloves, and chop fresh parsley for garnish.

Measure out the Worcestershire sauce, Guinness, beef broth, rosemary, thyme, bay leaves, salt, and pepper into small bowls or cups.

Sift the xanthan gum through a fine mesh strainer to break up any lumps—this prevents it from clumping when added to the hot stew.

Step 2: Sear the Beef to Develop Deep Flavor

• 2 tbsp olive oil
• 2.2 lb beef chunks

Heat 2 tablespoons of olive oil in a large heavy-bottomed pot or Dutch oven over medium-high heat until shimmering.

Working in batches to avoid overcrowding, brown the beef chunks on all sides until they develop a rich golden-brown crust—this typically takes 2-3 minutes per batch.

Don’t stir constantly; let each side caramelize before turning.

Transfer the browned beef to a clean plate and set aside.

Step 3: Build the Aromatic Base

• 1 large onion, diced
• 3 garlic cloves, minced
• 1 tsp Worcestershire sauce

In the same pot with the rendered beef fat, add the diced onion and cook for 5 minutes, stirring occasionally, until softened and translucent.

Add the minced garlic and cook for another 30 seconds until fragrant.

Deglaze the pot by pouring in the Worcestershire sauce and scraping up any browned bits stuck to the bottom—these flavorful browned bits add incredible depth to your stew.

Step 4: Build the Stew Base and Transfer to Oven

• seared beef from Step 2
• 14.9 oz Guinness stout
• 2.5 cups beef broth
• 3 carrots, cut into pieces from Step 1
• 3 celery stalks, cut into pieces from Step 1
• 2.2 lb root vegetables
• 1.5 tsp rosemary
• 1.5 tsp thyme
• 2 bay leaves

Return the seared beef to the pot along with any accumulated juices.

Pour in the Guinness stout and beef broth, then add the carrots, celery, root vegetables, rosemary, thyme, and bay leaves.

Stir well to combine all ingredients, ensuring the vegetables are partially submerged.

Bring the mixture to a simmer on the stovetop, then cover and transfer to a 325°F oven for 3 hours.

The beef should become fork-tender and the flavors will meld beautifully.

Step 5: Thicken the Stew with Xanthan Gum

• 1/4 tsp xanthan gum, sifted
• 1.25 tsp salt
• 1 tsp black pepper

Remove the stew from the oven and place it on the stovetop over medium heat.

Slowly sprinkle in the sifted xanthan gum while stirring constantly—I add it gradually and stir vigorously to prevent lumps from forming.

Simmer for 2-3 minutes until the stew reaches your desired thickness.

Taste and adjust seasoning with the measured salt and black pepper, adding more if needed.

Step 6: Serve and Garnish

• fresh parsley

Ladle the rich, hearty stew into bowls and top with fresh chopped parsley.

The stew is best served immediately while it’s hot and fragrant.
