Ingredient Notes:

- Chicken leg quarters - I love these because they have a lot of meat. You can also use regular bone-in chicken thighs or legs too!
- Ketchup - You can use any brand. Although most ketchup is gluten free, it is good always to read the labels.
- Mustard - I like to use brown mustard because it adds more flavor. You can also use Dijon if you prefer.
- Spices - Chili powder, paprika, garlic powder, salt and pepper. Be sure your spices are gluten-free and not processed on shared equipment if you are sensitive to gluten.
This is the slow cooker I own. I bought it a couple of years ago, and it is still going strong! This Crock Pot can hold a whole 3-pound chicken and does a great job cooking!
- Holds a lot of food
- Easy cleanup
- Cooks evenly
- It doesn't have an auto-switch from high to low temp
What slow cooker is best?
Any slow cooker will work well; I find the size is the most important because I like to cook a big meal so that there are leftovers to freeze. I use this 7-quart Crock Pot.
Recipe Step-By-Step Directions:

Step 1: In a small bowl, add the sauce ingredients and mix well.
Step 2: Add the chicken leg quarters and sliced onions to the slow cooker.
HINT: I created this slow cooker chicken quarters recipe to be a dump-and-go recipe because I wanted it to be the easiest possible. If you like a browned finish for your chicken, I would encourage you to brown it in a hot oiled skillet on each side for 4 minutes before adding it to the slow cooker.

Step 3: Smother the sauce over the chicken and add the water to the slow cooker. Cover the slow cooker and cook on high for 4 hours or low for 6 hours.
Variations:
You can vary the flavors in this barbecue slow cooker chicken legs recipe.
- You can make this slow cooker chicken with mushrooms or add veggies like carrots and potatoes.
- Add some spice by adding ½ teaspoon of crushed red peppers to the barbecue sauce.
- Use boneless chicken breasts and shred the meat when cooked so you can use it for sandwiches.
Storage:
This easy slow cooker BBQ chicken will keep for up to 4 days in an air-tight container or for up to 4 months in the freezer.
Add this chicken to a freezer-safe zip-style bag and press the extra air out to freeze it.
Tips and Recipe FAQ:
You can definitely put raw chicken in your slow cooker. That is how it cooks with all of the flavors from the sauce.
The chicken will make a lot of liquid as it cooks, so covering the chicken in liquid is unnecessary.
Although hard, you can overcook your chicken in a slow cooker. Always stick to a recipe's cooking time for the best results.
Unfortunately, you can not cook frozen chicken in a slow cooker. The temperature is too low, and the chicken can spoil cooking so slowly.

I just left a comment and meant to put avocado *oil and also meant that I don’t*plan to brown my chicken beforehand. Sorry for the typos . Fara
Fara
Hello- I’m planning on making this tonight but I have a question. The avocado o that’s in the recipe- does that go into the ingredients for the sauce or is that oil to be used if someone wanted to brown their chicken beforehand in a skillet? Also, if I don’t have avocado oil, would olive oil suffice? I do t plan on browning my chicken first but I’m asking in case it’s supposed to go into the BBQ sauce recipe. Thanks so much, Fara
Sandi Gaertner
Hi Fara, that oil goes into the sauce. I don't brown the chicken beforehand. You can brown it if you like.

I tried the recipe using store bought bbq sauce. Not sure what happened but my sauce, when done was liquidity. I like a thicker sauce. Perhaps it's the liquid from the chicken. The flavor was good.

Hi Mark, it was the liquid from the chicken. The barbecue sauce recipe I include was seasoned for the extra liquid. I haven't made this recipe with store-bought bbq sauce, but if you use that, you would want to use more and maybe less water.
