This Slow Cooker Chicken Breast recipe comes out perfectly juicy and seasoned every time! Learn my tips for getting the best crockpot chicken breast, perfect for salads, sandwiches or an easy dinner.

I KNOW.

Boring, right??

Except, perfect slow cooker chicken breast isn’t boring at all.

This chicken is so flavorful, and so juicy, with just a few ingredients (and one secret ingredient!).

I will admit, I have made plenty of dry, overcooked, unpalatable boneless chicken breasts in the slow cooker. I’m not proud of it, but we all do it every now and then, am I right??

I wanted to come up with a foolproof way to make great crockpot chicken breast — that is big on flavor (but still versatile enough to use it a variety of different ways or add your own sauce at the end), and ridiculously juicy.

Naturally, I started with this Crockpot Shredded Chicken recipe as my base, since so many of you have already loved it (check out this Instant Pot Shredded Chicken if that’s more your style!), but I made a couple swaps and additions for an extra little boost of flavor.

This slow cooker chicken recipe is perfect just on its own, with a side of rice or noodles or a big salad if that’s your thing, but if you’ve got leftovers?

Throw them in this Crockpot Chicken Spaghetti the next day, or swap the ground beef for chicken in this Rigatoni Pasta Bake.

How to make perfect Slow Cooker Chicken Breast:

1. Choose good quality chicken. I’m not saying it has to be expensive (I buy my chicken breasts frozen when they’re on sale!), but overtime I’ve noticed that there can be a real difference in quality from one box of chicken breasts to the next. Find a kind you’re happy with it and stick with it.
2. Not too full or too empty: I use this 2.5 quart crockpot for, honestly? Almost everything these days. It’s the perfect size for 4 or 6 chicken breasts. I’ve found if I cook just a couple chicken breasts in a larger crockpot, it cooks more quickly and is more prone to overcooking. When you have your slow cooker at least half full, it gives the chicken a little “insulation” and prevents it from cooking too quickly.
3. To sear or not to sear. I tried both ways because I like to know what I’m talking about when I’m giving you the most delicious slow cooker chicken breast you’ve ever had. What I found was not a lot of difference between the two. If you want to sear it beforehand, go ahead, if you’re frazzled enough as it is and want to dump and go, do that.
4. Butter (my secret ingredient that makes all the difference). Or margarine. Another moment of honesty — I use margarine a lot. I just don’t hate it. Chicken thighs are known to have much better flavor and juiciness than breasts, and it’s because they have 3x the amount of fat. I figured if I added just a little bit of fat into the slow cooker, I could give my chicken breasts some of that some fat love. (SPOILER: it works. It’s delicious, and not even drowning in half a cup).
5. Don’t overcook. If you want a longer cook time, try filling your slow cooker more than half full, as this slows down the cooking process some.

Tips for making frozen chicken in the crockpot:

Here’s the truth:

I woke up one morning, the morning I wanted to start testing this slow cooker chicken breast, with my chicken breasts still rock solid in the freezer because I, like many parents of 3 kids 6 and under, had forgotten to take them out.

Rather than cooking frozen chicken in the crockpot, I placed my chicken breasts in a large freezer bag, sealed it tight, and covered them with cool water (think perfectly not cold or not warm), and let them sit about 20 minutes. Flip, and let sit another 20 minutes. Perfectly thawed.

I threw them in the slow cooker and away I went.

It’s not that you can’t cook frozen chicken in the crockpot — it’s just that I knew they would cook more evenly and probably be better if I didn’t.

Now, I’ve cooked frozen chicken breasts plenty of times (remember that I used to work outside of the house and be gone for 8+ hours a day), and they’ve been just fine.

They will release more moisture and cook a little less evenly, but the world will (probably) not end.
