Anyone else love a low-maintenance dinner? One that takes easy simple prep and then you just pop it all in the oven and let it do its thing? Same. That's exactly what this Healthy Chicken Leek and Potato Bake is! Baked chicken with fresh leeks and potatoes in a light, but flavorful lemon thyme vinaigrette. A gluten-free baked chicken dinner that's takes some time to cook, but a set it and forget kind of a meal.
Ingredients Needed
- Chicken - We love chicken breasts for this recipe. Bone-in thighs would also work for this cook time, but boneless thighs will cook faster than the potatoes.
- Leeks - Everytime I cook with leeks I realize that we don't cook with them enough! Their sweet oniony flavor pairs perfectly with chicken, potatoes, and thyme!
- Onion and Garlic- More allums! Because leeks, garlic, and onions together is just delicious. We use white onion because that's our favorite, but you could also use a sweet yellow, too.
- Potatoes - Our favortie for this are small red potatoes, but any potato would be great. Just be sure to cut them up small, about 1-1/2 inches to ensure they're all well cooked through.
- Spices - Salt and pepper, of course, but then also plenty of thyme and just a little ground mustard, which is such a complimentary flavor to not only leeks, but also thyme!
- Olive Oil and Lemon Juice - To create your vinairgrette to mix it all in. An extra virgin olive oil is the best for a vinairgrette and we always like to use a nice olive oil, like this one.
Step-by-Step Instructions
Always clean your leeks!
The first step is to get all of the little bits of dirt that can hide out in between the layers of your beautiful leeks. All it takes to do that is to slice off the white and light green parts of the leek and soak them in some water. Meanwhile, you can give your little potatoes a choppity chop.
Vinaigrette
This is where all of that fresh, bright flavor comes from that just perfectly highlights all of the components of this healthy chicken bake.
Mix it all Together
Add all of your rinsed leeks, potatoes, garlic, and onion together in a bowl and give it a good mix with the vinairgrette.
Season Chicken and Add it all to a Baking Dish
Give that chicken a good season and then add it to your baking dish. Make sure that your chicken rests on the bottom of that baking dish, it'll help it cook faster.
Bake!
Baked for 45-60 minutes (dependent upon the side of your chicken breasts) and you have a light and bright Healthy Chicken Leek and Potato Bake with juicy chicken breasts and leeks and potatoes that are tender and full of spring flavors!
If you love the flavors of leek and potato together, then you have to try our Healthy Leek and Potato Soup! Or another recipe with leeks, our German Potato Salad!
Baking Tips
For cutting leeks, you will want to cut off the root of the leek off and then slice them in rounds just before it starts to turn dark green. All of the white and light green parts of the leeks is the good stuff!
Have you noticed lately how incredibly large chicken breasts (even organic ones) are getting? Those big breasts are going to take longer, so somtimes we cut them in half for this recipe, which cuts down on the cooking time. To be sure, we always check with our Instant Read Thermometer that the internal temperature of the chicken has reached at least 165 degrees.
Either of course works great. 1 teaspoon of dried thyme = 1 tablespoon of fresh. We prefer to use mostly dried in this recipe because 2 tablespoons of fresh thyme is a lot to clean off of those tiny little twigs!
This will also ensure even cooking since there's nothing worse than having a dish where some potatoes are fully cooked and others are not.
C'mon Spring! We're ready for you and all of your gorgeous produce.
