Crispy Guinness beer battered onion rings with a Dijon mustard dip and seasoned with fresh rosemary.

If I was told I could take three things to a desert island, my list would probably be an onion, flour and some oil. I have a serious veggie crush on beer battered onion rings and I’ll regularly ask for them in place of french fries if the chance comes up when I’m eating out.

But they have to be big and crispy, not those weird breaded versions that you sometimes find at some fast food places. They have to be seasoned well with lots of salt and the onion has to separate when you bite into it. Can you tell I’m picky about my rings?

Making onion rings isn’t that difficult but preparation is important. Every ingredient has to be ready at hand and because most of us don’t own a restaurant sized fryer, you have to work fast.

The house is going to smell like oil for days and clean-up sucks big time, but if you love them as much as I do It’s so worth it. I love using beer when I make a batter for frying, fish tacos and fish n’ chips always get cooked this way in my kitchen and with so many amazing craft beers available, don’t settle for using a tasteless light beer.

The Guinness gave me a deep, dark brown batter and the flavor really came through. Because I’m a dipper, I made an easy mayonnaise and Dijon dip with…yup more Guinness. Add these to your St Patrick’s Day menu but don’t feel bad if you make them in the middle of August too, it’s totally acceptable!
