chicken thighs, garlic, salt and pepper, carrots and butter on a wooden table.

Be careful with leeks, they can have sand in them, the sand is very visible. You can rinse the leeks after they are sliced or before if you cut them length wise and spread out the layers.

This recipe is mostly flavored by the leeks and 4 cloves of garlic. Not much else is needed to make this dish shine, plenty of flavor from that and the chicken thighs themselves.

I made homemade mashed potatoes to go with this. I usually avoid making mashed potatoes, but the whole family enjoys it so much I have to do it once in a while. I had heavy cream in my fridge and that makes the BEST potatoes. The sauce that is made while this dish cooks is great, it’s flavored with leeks, garlic, butter and the chicken juices. Be sure to ladle those juices over the chicken on the plates.

    This recipe is absolutely fantastic! My wife and I make this any week that we can get Chicken Thighs on sale, meaning it’s usually 2-3 times a month.

    Our only modification is that we use only one leek as opposed to three, but that’s just a matter of preference. Thank you so much for converting me to loving chicken thighs, and for giving me the most economical recipe I’ve got! This staple of our kitchen allows us to feed three adults for around $6-$7.

    Can you freeze this?

    1. Sarah Olson says:

      Yes! It will freeze well!

  3. Jenn says:

    Can you cook this on high? And for how long ?

    1. Sarah Olson says:

      I would do 4-5 hours on high. I like my chicken thighs to be pretty tender.
