Why does slow cooked chicken thigh taste better with the bone in?

I always use chicken thigh the the bone in for slow cooking. As your dog is well aware, bones contain a lot of flavour. Note: don’t give dogs or cats cooked chicken bones, they are too sharp. That flavour infuses into the meat when cooked, especially in a slow cooker where that process lasts for hours.

Will the chicken thigh skin get crispy in the slow cooker?

The chicken skin won’t get crispy, but because we’re not adding any liquid. It won’t be soggy; it’ll be firm enough to bite into.

If you have an air fryer, popping the skin-on thighs in there for 5 minutes at 200 degrees Celsius (390 degrees Fahrenheit) will get you a nice crispy finish. Make sure you brush off the onions before putting the thigh into the air fryer though – we don’t want to reduce those to nothing.

Why pan fry the chicken before putting it in the slow cooker?

Pan-frying the chicken before placing it in the slow cooker can be beneficial for several reasons. Firstly, pan-frying helps to bring out more flavour and caramelise the outer layer of the chicken.

This caramelisation helps to seal in moisture and create a crust that will keep your chicken succulent. Additionally, high heat helps tenderise the chicken by breaking down some of its proteins and fibres. This leads to a more flavourful and tender result.

When searing your chicken in a pan make sure you use enough oil and butter. They help to prevent sticking whilst adding flavour into your dish. I prefer to use tallow as it’ll give your chicken stacks of flavour and colour.

You should also season your chicken generously with salt and pepper before pan frying. This will help bring out the natural flavours of the meat. In this recipe we’re also going to use lemon juice.

You’ll sear them until they have some good colour. Then transfer your seared pieces directly into the slow cooker with whatever aromatics you’d like to add for extra flavour. Whether that’s onion, carrots, garlic etc. I also cook those aromatics in the pan before putting them in the slow cooker. Again, it’s all about getting the maximum flavour and colour.

Do I need to add any liquid to slow cooker chicken thighs?

You don’t need to add liquid to the slow cooker when cooking chicken thighs on low. The natural juices from the thigh will be released throughout cooking. Having the slow cooker on low will mean those juices don’t evaporate.

If you’re cooking chicken breast, or if you’re cooking thighs on high, a little liquid helps keep the chicken moist. This prevents it from drying out in the long cooking process. The best liquids for slow cooked chicken include broth, white wine or water.

Do I need to marinate chicken before putting it in the slow cooker?

Marinading chicken before cooking it in the slow cooker is not necessary, but can be beneficial. Marinades are a great way to add flavour and lock in moisture. A marinade typically consists of an acidic component (like lemon juice, vinegar or yogurt), oil and herbs and spices, which helps tenderise the meat.

However, this recipe is really simple and is aimed at being quick. So we’re not using a marinade as such, just a little lemon juice, salt and pepper. The whole thing will come out extremely moist, tender and flavourful from the slow cooker.

Is it OK to put raw chicken in the slow cooker?

It’s perfectly OK to put your chicken in the slow cooker raw. I do exactly that in this one-pot slow-cooked chicken recipe. As long as the internal temperature of the chicken gets to 75 degrees C (165 degrees F) you’re good. Unless your slow cooker is broken, it’ll get to this temperature. If you’re unsure what temperature your slow cooker operates at, check with the manufacturer’s guidelines. Having a probe thermometer in your kitchen kit is a really good idea. It’s an easy way to remove doubt in these situations and will come in handy for other things.

Is it better to cook chicken thighs slow or fast?

It is generally better to cook chicken thighs slow rather than fast. Slow cooking allows more time for the meat to absorb flavours from seasonings and any other ingredients used, creating a more flavourful dish.

Additionally, cooking chicken thighs slowly helps keep them tender and juicy, rather than dry and tough. The latter can happen if cooked for too long at high temperatures. This is why a slow cooker is perfect for this recipe. Even with the slow cooker on high for a few hours, you’d still get tender chicken. We’re going to keep it on low for 4 hours. This gives us those wonderful juices to spoon over the chicken and sweet potato at the end.

However, when frying or sautéing chicken thighs before putting them it is best to use high heat. This is to brown the outside of the meat for a golden crust on each piece. This will provide an added layer of flavour as well as add texture to your dish!

How long to cook chicken thighs in the slow cooker?

There are a few considerations here. Thighs tend to have a higher fat content than other cuts of chicken. This results in a more flavourful dish. Generally, it is recommended to cook chicken thighs in the slow cooker for 4-5 hours on low or 2-3 hours on high.

However, depending on how large your pieces are, you may need to adjust your cooking time accordingly. Chicken thighs that are cut into smaller pieces may require less time compared to larger ones. While boneless skinless chicken thighs will cook faster than bone-in ones. In addition, if you are using frozen chicken thighs, the cooking time may be longer as well.

It is also important to note that if you are cooking your chicken with vegetables such as potatoes or carrots, these should be added at least halfway through. This is so they don’t become overly soft and mushy. Additionally, some vegetables such as onions and bell peppers release moisture during cooking which can prevent the chicken from becoming too dry. Adding certain herbs and spices such as rosemary or oregano at the beginning will help infuse more flavour into your dish throughout its cooking process.

Finally, always check that the internal temperature of your cooked poultry has reached 75 degrees Celsius (165 degrees Fahrenheit) before serving it up. This ensures that any potential bacteria has been killed off while guaranteeing juicy and succulent meat each time!

Can I do chicken breast in the slow cooker?

Yes, you can cook chicken breast in the slow cooker, but this recipe works best with chicken thighs. When using a slow cooker to make chicken breasts, you should add some liquid. This is because they don’t have the fat content of chicken thighs and so run the risk of getting dry.

But…

You don’t need to use a slow cooker for chicken breast at all. Chicken breast only takes 16-18 minutes in the oven at 220 degrees Celsius (430 degrees Fahrenheit). So how much time are you really saving?

To guarantee chicken breast stays moist in the oven cover it for the entire cook. Save the slow cooker for bone-in chicken recipes like this one.
