Vegetarian Irish Stew

A vegetarian twist – but a delightfully delicious twist – on a classic stew, Vegetarian Irish Stew uses hearty, saucy lentils and authentic Guinness Stout to create a rich, flavorful dish (also, it’s vegan!).

The season of heavy foods is winding down (com’on, Spring!), but we can’t neglect our adopted Irish holiday, featuring green beer, festive parades with curly-topped Irish dancers, and, of course, a big bowl of Irish stew.

Did you know that the St. Patrick’s Day parade in Savannah, Georgia, is second only to New York in scale and grandeur — not Boston or Chicago, but lovely Savannah! — and that it’s the culmination of their week-long celebration? I didn’t know myself, until I took a remote job with a company based in Georgia, who often closed the office on March 17th, lol.

I’m one quarter Irish, so, Erin Go Bragh! My own town with its strong German heritage skims over this celebration — we rock the Oktoberfest (World’s Largest Chicken Dance, y’all!) — so I’m usually left to my own devices if I want to get my Irish on.

I’m too much of an introvert for parades and dancing, so I do my celebrating from the kitchen.

Vegetarian Irish Stew for lentil lovers in a bowl, topped with mashed potatoes

Irish stew traditionally features frugal cuts of lamb or beef, but for us veggie lovers, lentils step in quite nicely. Rounded out with a generous helping of root vegetables and select seasonings, I’m confident going out on a limb and predicting that even carnivores will love this stew.

Serve it with a side of creamy mashed potatoes, and these quick-and-easy Skillet Irish Soda Bread Minis, and it’s got comfort-food dinner written all over it.

Vegetarian Irish Stew with Guinness

Speaking of beloved Irish traditions, beer lovers got some great news last year, when Guinness transitioned some of its facilities to use vegan processes.

The ingredients of beer are naturally vegan, however, many breweries use isinglass in the processing of their beers. Isinglass is a gelatin derived from the swim bladders of fish (for anyone thinking it had something to do with Lord of the Rings, like I might or might not have before looking it up, lol). It’s used as a clarifying agent in beer and wine.

So, I was more than happy to flavor-up my vegetarian Irish stew (it’s vegan too) with a generous pour of authentic Guinness Stout, which, like cooking with wine, adds an extra richness and flavor boost.

If you’re looking for a meatless option for St. Paddy’s Day festivities, I think you’ll find lentil stew a worthy replacement for the classic beefy stews. Go Green!

Vegetarian Irish Stew for Lentil Lovers

A vegan twist - but a delightful delicious twist - on Irish stew uses hearty lentils and authentic Guinness Stout (it's vegan!).
Prep Time15 minutes

Author: Karen Gibson


  • 1 tablespoon olive oil
  • 1 medium onion diced
  • 2 ribs celery diced
  • 1 medium potato diced (about one cup)
  • 1 small turnip diced (about 1/2 cup)
  • 1 large carrot diced
  • 4 ounces mushrooms roughly chopped
  • 2 cloves garlic minced
  • 1/3 cup Guinness beer (or your favorite)
  • 3 cups vegetable broth
  • 4 tablespoons tomato paste (1/4 cup)
  • 2 teaspoons smoked paprika
  • 3 tablespoons all-purpose flour
  • 1 teaspoon sweet/mild miso (optional)
  • 1 teaspoon dried marjoram
  • 1 teaspoon dried parsley
  • 1 bayleaf
  • 1 cup French green lentils (French du Puy lentils)


  • Heat the olive oil or 2 Tbs broth in a 4 to 5 quart Dutch oven or soup pot over medium heat. Add the onions and celery and cook until translucent. Add the potatoes, turnips, carrots, mushrooms, and garlic, stir well and cover pot with a lid. Cook for 10 minutes, or until the vegetables have given off some liquid.
  • Scootch the vegetables to one side and tip the pot to pool liquids to the cleared area (or, if dry, add a splash of vegetable broth). Spoon the tomato paste into the liquid, and top with the smoked paprika. Stir to create a paste, and let cook until fragrant.
  • Add a splash of vegetable broth to the pot, and sprinkle the flour over the vegetables. Mix the tomato paste into the vegetables, and stir until the flour has disappeared into the vegetables. Add the beer, and let simmer, to cook off the alcohol.
  • Add the remaining broth, miso, herbs, and lentils. When the stew begins to boil, reduce heat to maintain a gentle but active simmer (medium-low should do it). Cover partially with the lid, and cook for 45 minutes, stirring occasionally.
  • Remove bay leaf, and let stew rest on warm/low for 10 minutes before serving.
  • Stew can be made ahead (even the day before). When rewarming, if the stew is too thick, add vegetable broth by the tablespoon until it reaches the consistency you prefer. Taste, and add salt for seasoning, if desired.
  • For a winter comforting treat, serve with mashed potatoes.

So, good! I only used potatoes and added XX beer while cooking and just a little Tobasco in the bowl. An international delight. I served it the first time with brown rice, but I put the leftovers in pint jars to take for my lunch. So good!

Hello from Connecticut! I am excited to try this recipe tomorrow but I am just a little unsure when to add the splash of Guinness. When do you recommend? Thank you for sharing!!


Tuesday 12th of March 2019

So sorry about that! I've updated the recipe. I'd like have an excuse for leaving out the key thing that makes it sort of Irish, but I just don't. :D


Monday 11th of March 2019

You may think I’ve had too much Guinness already but I’m missing where the G-beer? goes in the recipe. Shall we only serve it on the side??


Tuesday 12th of March 2019

I think I'm the one who had too much Guinness when typing up this post, lol. I've updated the recipe - thanks so much for point out the omission!

I am now craving lentils and Guiness which has never happened before, even in my crazy food addicted brain!

Can't wait to try it!

Karen, this stew looks so inviting. Make me warm and cozy on the inside, especially during this wintery craziness here in the Midwest. Thanks for posting. And I'm with you - I also, am too much of an introvert for parades and dancing. Love to watch them though. Happy St. Patrick's day coming up soon.

That's exactly why I love stews! Especially in a big bowl, curled up in front of the TV (<<< introvert goals, lol)
