Recipe: Vegetarian Irish Stew with Sweet Potatoes and Tempeh

Vegetarian Irish Stew with Sweet Potatoes & Tempeh
I am not a big holiday person. In fact, I’m kind of a party pooper when it comes to holidays. On St. Patrick’s Day, I make an effort not to wear green. Because if I accidentally do wear green? Well, someone might think I’m in the holiday spirit. And we wouldn’t want that, would we?

So now that you know I’m a complete killjoy (I also like to rain on parades and steal candy from babies), let me tell you what St. Patrick’s Day means to me. It’s my Grandpa’s birthday! So, since I know my grandparents will be reading this, I want to wish my Grandpa a HAPPY BIRTHDAY!

St. Patrick’s Day is also a good excuse to break out the Guinness, one of the few beers that I actually enjoy drinking. But even better than drinking Guinness is cooking with Guinness. Since I’ve been coming up with recipes involving sweet potatoes all week, I decided to try doing a vegetarian Irish stew with sweet potatoes and Guinness. I added tempeh for protein and lentils because we had them on hand (why not, right?). The result was a hearty vegetarian Irish stew that even a meat eater could love.

    This is such an awesome recipe! I love how you put such a unique twist on cooking for St. Patrick's day, as I don't think I've ever seen a St. Paddy's day-themed recipe with tempeh in it. Thanks for linking this up to the FaveDiets blog hop!

    Thank you so much for this recipe! I made it last week and my meat-eating husband loved it. I didn’t have sweet potatoes on hand so made it with regular potatoes. Wonderful! I’d recommend it to anyone!

    Recipe looks great! Just an FYI, Guinness is not considered vegan, they still use isinglass (fish bladder)as a filtering agent. source Barnivore

      I would skip it. I’m pregnant too and I’ve done a lot of research about cooking with alcohol because I LOVE to cook with wine and beer. While a lot of the alcohol does cook off, not all of it does. There’s no amount of alcohol considered “safe” during pregnancy because there’s never been any research to figure out what safe levels would be. A lot of women will still cook with it and enjoy an occasional glass of wine during pregnancy and the baby is just fine, but others abstain entirely. It’s really up to you, but I’ve decided to abstain just because I know myself and I’m a worrier. 🙂
