The Perfect Keto/Low Carb Irish-Inspired Chicken Dinner

Chicken, leeks, and mushrooms are a couple of my favorite ingredients to cook with – especially as the calendar turns closer to spring, and everyone starts thinking about our favorite recipes to celebrate the Green, White, and Orange – and all things Irish! This dinner is inspired by meals I’ve had while traveling across Ireland and the simple, delicious farm-fresh flavors I love finding across the Emerald Isle.

This easy chicken and leek dinner is the best way to celebrate Irish food if you’re on a low carb or keto diet – since we’re not adding carbs from potatoes or wheat – though this recipe IS amazing with some potatoes tossed in, too.

This super-easy sheet pan dinner is absolutely bursting with flavor – even though all you have to do to prepare it is dump the ingredients on a sheet pan and toss it in the oven!

This easy chicken leek and mushroom dinner is a complete meal on just one pan – with almost no work. You can even dice up some potatoes to bake with the chicken and leeks for a crowd pleasing Irish feast everyone will love. Simply add 1-2 potatoes, rinsed, scrubbed, and cut into small 1-2″ bits to be sure they cook with the chicken.

How to Make Roasted Chicken and Leeks

First assemble the following ingredients:

  • 6 chicken thighs, skin off, bone-out
  • 3 tbsp olive oil
  • 1/4 cup garlic, diced
  • 1 tbsp sea salt
  • 1 tbsp onion powder
  • 2 tsp pepper, fresh cracked
  • 8 oz cremini mushrooms, sliced thin
  • 2 leeks, large – white ends sliced thin, discard woody green ends.

Use this Method

Combine. Preheat oven to 375 degrees. Add chicken, leeks, and mushrooms to a sheet pan.

Prep. Drizzle with olive oil, then sprinkle with garlic powder and herbs. Toss over ingredients to coat evenly. Spread diced garlic over dish.

Bake. Cover with foil and bake for 25 minutes. Remove foil and bake another 10-15 minutes, until chicken is browned and has reached 165 degrees internal temperature. Remove from oven and serve immediately.

Tips and Tricks to Make Sheet Pan Oven Roasted Chicken and Leeks

This roasted chicken and leek dinner is a super easy all-in-one meal – but there are a couple of tips and tricks to ensure perfect, juicy chicken and garlicky, flavor packed leeks that everyone will love!

Make it Easy Clean

This dinner is so wonderful because it’s crazy easy – AND easy to clean! Simply pop down some foil or parchment paper, and chuck the mess in the trash when you’re done – no pots and pans to clean!

Stir Occasionally To Prevent Burning

It’s optional, but I try to stir the dish around a bit as it cooks to make sure the mushrooms and leeks crisp up and cook evenly. Again – this isn’t necessary, but I think it helps the vegetables soften, crisp, and brown better.

Cover, then crisp

Start the recipe off covered, and then remove the foil partway through to cook it without burning the chicken or vegetables for the perfect easy dinner!

  1. Easy and delicious. I served this over basmati rice with some asparagus as a side dish. Will definitely make this again for company.

  2. Just made this the other night. Perfect for the busiest of evenings. I added the potatoes and kept them away from the mushrooms so the liquid wouldn’t absorb and my little ones would eat. Great recipe!

  3. Made this for dinner the other night. This could not be easier and more delish! I added potatoes and put them in the opposite corner from the mushrooms to avoid the liquid absorbing. So good!
