Crock Pot Barbecue Chicken with Homemade BBQ Sauce

Jump to Recipe·Print Recipe·Trust With Google·Leave a Review

My dad has a running joke about the size of the crowd at my house. Every Sunday he asks whether Andre Dickens is coming — the mayor — because it’s usually half of Atlanta standing in my kitchen. Cookouts are no different, and crock pot barbecue chicken is what I put out for everybody I didn’t plan for.

A crock pot barbecue chicken slider piled with shredded chicken and coleslaw on a wooden board

It goes on next to the oven baked ribs and the pulled pork, and it’s the pan anyone who doesn’t eat pork can actually eat — which, at a table this size, is always somebody. Three pounds of chicken breast, a barbecue sauce you build right in the pot out of ketchup and vinegar and brown sugar and a grated onion, and it holds on warm for hours while people wander in. Pile it on slider buns with slaw, or put it next to a scoop of crock pot mac and cheese. If you’re building a whole spread around it, my Labor Day cookout game plan will tell you what time to start.

Ingredients for Crock Pot Barbecue Chicken

Everything goes in raw and cold. There's no browning step, no sauce to simmer first, and nothing here that you can't find in a normal grocery store.

Boneless skinless chicken breasts - I use breasts because they're lean and this is already a sugary sauce. Thighs work, and they're more forgiving. See the substitutions below.
Ketchup - the backbone of the sauce.
Apple cider vinegar - the tang that keeps it from tasting like candy.
Worcestershire sauce - savory depth. Don't skip it.
Brown sugar - light or dark, both fine.
Yellow mustard - plain old yellow, not Dijon.
Paprika - sweet paprika. Smoked works too if you want it to taste like it came off a grill.
Onion - grated on a box grater, not chopped. Grated onion melts into the sauce; chopped onion stays chunky.
Garlic - fresh, minced.
Salt and black pepper

See the recipe card for quantities.

Why You'll Love This Crock Pot Barbecue Chicken

You're making the sauce, not buying it. Nine pantry ingredients, no corn syrup, no bottle. It tastes like barbecue sauce because it is barbecue sauce.
It's lean. Three pounds of chicken breast is a lot of protein for a cookout main, and it holds its own next to the ribs without being a third pork dish.
Dump and go. Everything goes in raw. You're not searing anything.
It feeds a crowd and it holds. Once it's shredded it sits on warm indefinitely, which is the entire reason it lives in my cookout timeline.
The leftovers are better. Nachos. Every time.

How to Make Crock Pot Barbecue Chicken

The liquid step in the middle is the one to pay attention to. Everything else is dump and wait.

Raw chicken breasts coated in homemade barbecue sauce in a crock pot before cooking

Load the Crock Pot

Put the chicken breasts in the crock pot, then add the ketchup, apple cider vinegar, Worcestershire, brown sugar, mustard, paprika, grated onion, garlic, salt and pepper right on top. Stir it around so the chicken is coated. Cook on high for 3 hours or low for 6 hours.

Two forks pulling cooked chicken apart into shreds on a sheet pan

Shred the Chicken and Pull the Liquid Off

Move the chicken to a sheet pan or a large serving dish and shred it with two forks. Set aside. Ladle 2 to 3 cups of the cooking liquid out of the crock pot and set it aside. You want roughly 1½ cups left in the bottom. Use your judgment here - some batches throw off more than others.

Add The Chicken Back To The Crock Pot

Return the shredded chicken to the crock pot and stir it through the sauce that's left. Let it sit for 30 minutes so it soaks the sauce back up.

Serve

Use tongs to pile shredded chicken on top of sliders or buns, top with your favorite bbq sauce and some sweet and tangy coleslaw.

Substitutions

Nothing here is precious. Swap what you've got.

Chicken thighs instead of breasts - boneless skinless thighs work and they're harder to overcook. I stick with breasts because I want the leaner, higher-protein version, but if you like dark meat, use it. Cooking time doesn't change.
White vinegar or red wine vinegar instead of apple cider vinegar. You'll lose a little of the fruity edge.
Honey or maple syrup instead of brown sugar. Start with a little less; both are sweeter than they look.
Dijon instead of yellow mustard, if that's what's open. It's sharper.
Smoked paprika instead of sweet paprika if you want it to taste like it came off a grill.
Onion powder if you don't feel like grating an onion. It's not the same, but it's fine.

Variations

One pot of this turns into four different dinners depending on what you put under it.

Sliders. Toasted brioche buns, a pile of chicken, slaw on top. This is how it gets eaten at my house.
Barbecue chicken nachos. Tortilla chips, the shredded chicken, cheese, red onion, jalapeño, corn, sour cream and a handful of cilantro. This is the leftover plan and it's better than the original dinner.
Spicy. A tablespoon of hot sauce or a big pinch of cayenne into the sauce at the start.
Loaded baked potatoes. Split a russet, butter it, pile the chicken on, cheese and scallions.
Bowls. Chicken over rice with slaw and pickled onions if you're skipping bread.

Equipment

You need a crock pot and a box grater. Everything else you already own.

Slow cooker. A 6-quart is the right size for three pounds of chicken. Anything smaller and the breasts stack instead of sitting in one layer. Premium: GreenLife 6QT Ceramic Nonstick Slow Cooker - the insert is PFAS-free ceramic and it goes on the cooktop, which matters if you want to reduce the sauce without dirtying a second pan. Budget: Crock-Pot 6 Quart Cook & Carry - the lid latches, which is the whole reason it travels to other people's cookouts.
Box grater. For the onion, and it's the reason the sauce is smooth instead of chunky. Premium: KitchenAid Gourmet Box Grater. Budget: Spring Chef Stainless Steel Box Grater.
Sheet pan. Where the shredding happens, and the flat surface is the point. Premium: Nordic Ware Half Sheet Pan. Budget: Nordic Ware Naturals Half Sheet 2-Pack - buy two, you'll use both.
Meat shredding claws. Faster than forks once you're doing three pounds. Premium: Kitchen Mama Stainless Steel Meat Claws - steel tines, wooden handles, nothing plastic touching hot chicken. Budget: GORILLA GRIP BPA-Free Stainless Shredder. Two forks also work and cost nothing.
Small saucepan. Only if you're reducing the reserved liquid, but that's the step that turns this from good into very good. Premium: All-Clad D3 Saucepan. Budget: Cuisinart Chef's Classic 3-Quart Saucepan.

Storing Crock Pot Barbecue Chicken

Fridge. Airtight container, up to 4 days. Get it cooled and covered within two hours of cooking.
Freezer. Up to 3 months. Freeze it flat in a bag with some of its sauce so it doesn't dry out. Thaw overnight in the fridge.
Reheat. Low and covered - back in the crock pot on low, or in a saucepan over medium-low with a splash of water. Heat it through to 165°F. The microwave is fine for a single portion.
Make ahead. This is better on day two. If you're cooking for a party, make it the day before and reheat it in the crock pot on low.

Top Tip

Never shred the chicken in the pot. I've tried it every way looking for the shortcut and it doesn't exist - you can't judge how much liquid is under there, you can't get it out once the chicken's back in it, and you end up with barbecue soup. Sheet pan, two forks, ladle the liquid off, chicken back in. Ninety seconds of extra work.

Crock Pot Barbecue Chicken FAQ

Can I use chicken thighs instead of breasts?

Yes. Boneless skinless thighs work the same way and they're more forgiving if you leave the pot on too long. I use breasts on purpose - three pounds of lean chicken breast is a lot of protein, and the sauce is sweet enough that I don't want the extra richness on top of it. Cooking time stays the same either way.

Why is my crock pot barbecue chicken so watery?

Because chicken releases a lot of liquid as it cooks and a covered crock pot gives it nowhere to evaporate. It isn't something you did wrong. Take the chicken out, shred it on a sheet pan, and ladle 2 to 3 cups of liquid out of the pot before the chicken goes back in - you want about 1 ½ cups left. If you want that liquid back as sauce, simmer it down on the stove to a third of its volume first.

Can I cook it on low instead of high?

Yes, and low is the better option if you have the time. Six hours on low instead of three on high. The chicken shreds more easily and the sauce reduces a little more on its own while it cooks.

Can I make this ahead for a party?

Make it the day before. It's better on day two, and reheating it on low in the crock pot means it holds on warm through the whole party without drying out. If you're timing a full cookout around it, my Labor Day cookout game plan works backward from your dinner time and tells you exactly when to start.
