Lemon Chicken Thighs

Olive Oil  – You don’t need to use expensive extra-virgin olive oil here, but try and still use a good quality brand with a lovely peppery flavor.

Chicken Thighs – Choose free-range, corn fed or organic chicken if you can as they have more nutrition and will have more taste! You could use chicken drummers here too.

Salt – Sea salt does provide the best flavor here, so try and opt for this rather than regular table salt; however, either would be fine.

Black pepper – freshly ground if possible, but you could use the already ground version.

Sweet potatoes – Yams or sweet potatoes, orange or yellow flesh are great, so choose what’s available.  You could use butternut squash or pumpkin if you like.

Lemon – Use at room temperature to yield the most juice.

Garlic – You could use black garlic, smoked garlic, or regular garlic here.

Parsley – Fresh parsley does go well with this dish, but you could use dried parsley or another fresh herb, like thyme or rosemary.

What Sides Can You Have These Chicken Lemon Thighs?

This dish goes well with dark green leafy vegetables.  They are full of iron and Vitamins A, C, E, and K and pair perfectly with the sweetness of the potatoes.

Leafy greens such as spinach, kale, cabbage, and cavolo nero are great!

Steamed broccoli or cauliflower would also be good options and provide an extra boost of B Vitamins, calcium, and magnesium.

A mixed salad would be a delicious addition – try a mix of shredded iceberg lettuce, sliced cucumber, arugula, shredded salad onions, and micro herbs for a vibrant green glow next to the orange of the potatoes.

What Changes Could I Make to Use the Recipe Again?

This dish makes a great mid-week meal as it’s quick to prepare – perfect if you are working in the daytime and want to throw something in the oven.  Making a couple of adaptions can help you use this over and over!

Use a different cut of chicken – legs and drumsticks work well, but chicken breast may dry more quickly, so keep the skin on.

You could add some different flavors to the bake.  Try grating over fresh ginger root to pair with the lovely lemony taste.

Add some ground cumin to the salt and pepper and toss together before adding the lemon juice and garlic.

Like it spicy? Dice some red chili and mix this with the minced garlic before adding to the chicken.

You could remove the tray halfway through cooking and add some sliced zucchini and cherry tomatoes if you wanted to add some extra veggies.  Then return to the oven and carry-on baking until the chicken is cooked through.

How Long Will This Keep?

Once cooked, place in an airtight container in the fridge and use it within 3 days.  You can reheat in the oven but ensure the chicken is heated through thoroughly.

This dish would also freeze well.  Wrap well and place in the freezer and use within 4-6 weeks.

You can also prepare this dish ahead of time – chop, mince, and toss everything together and keep it in the fridge until you are ready to tip onto a baking tray to cook. It will be dinner in a flash!
