Enjoy a bounty of potatoes and garden-fresh veggies tossed in easy-breezy seasonings.

As an homage to Irish-American culture, potatoes O’Brien is a down-to-earth dish that combines potatoes with flavorful garden veggies. There’s a “family feel” to this staple meal that has stood the test of time through generations. Whether you’re grabbing a garnish from your own garden or picking potatoes from the local farmers market, you can appreciate the hearty simplicity of potatoes O’Brien.

Growing up, a couple of my best friends had Irish heritage, and their loudest and proudest time of year was – you guessed it – St. Patrick’s Day. I saw it as a kind of “Irish Thanksgiving,” because their families would come from near and far to enjoy a feast of gratitude together. They would share stories, make traditional dishes, and encourage each other during tough times. This is the exact “family feel” I’m talking about.

When I take a bite of potatoes O’Brien, I’m met with a nourishing blend of fluffy potatoes with sweet onion and peppers. Aromatic seasonings seal the deal and harmonize the veggies, making this dish easy for all ages and palates to enjoy. Share this simply satisfying, savory course at your next potluck, and you might just make some new friends!

Is Potatoes O’Brien Healthy?

Potatoes O’Brien is hearty, but its healthiness depends on how you make it, and will also depend on your dietary needs. Potatoes are starchy and high-carb, so this dish wouldn’t be suitable for folks on a low-carb diet, for example. That being said, it is vegan and gluten-free, since there are no animal products or wheat.

Ingredients for Potatoes O’Brien: Yukon Gold potatoes, diced red bell pepper, chopped yellow onion, sliced green bell pepper, olive oil, salt, garlic powder, and fresh parsley.

Sweet Potatoes O’Brien

To amplify the nutrition and switch up the flavors, try using sweet potatoes instead. Their earthy sweetness makes for an even warmer welcome at the dining table. In this version, I also like to add 1/2 teaspoon each of cinnamon, cardamom, and nutmeg to bring out some awesome autumnal flavors. You’d be surprised by how well sweet potatoes can go with bell peppers, but make sure to try the recipe’s original version first so you know exactly what to make for any occasion.

How to make ahead and store

I store potatoes O’Brien covered in the fridge for 3 to 5 days. Reheat on the stove with a bit of oil, or in the oven at 350 degrees F for 15 to 20 minutes. If you need to crisp them up again, it’s a good idea to fry them on the stove to brown the outsides.

Serving Suggestions

This dish stands strong on its own, but it can be emboldened by some powerful proteins. For breakfast or brunch, try serving potatoes O’Brien with a Baked Omelette, Soft-Boiled Eggs, or Keto Breakfast Casserole with Sausage.

For dinner, pair these precious potatoes with Oven-Cooked Top Sirloin Steak, Spatchcock Chicken, or Beef and Pork Meatloaf.

Lastly, my favorite vegetarian complement to these taters is a Honey Garlic Roasted Chickpeas Wrap.
