Slow Cooker Chicken Breast
Add Preferred Source
Slow cooker chicken breast is what I make on the nights I want a real dinner without standing over the stove to get it. The chicken cooks low in a garlicky Marsala and mushroom sauce, then finishes with a splash of cream that turns the juices glossy and rich.
One pound feeds four and the seasonings come straight from the pantry, so it’s an easy weeknight meal that still tastes like I made an effort. I sear the breasts for a couple of minutes first, because that quick browning is the difference between flat slow cooker chicken and something worth serving.

Why You’ll Love This Recipe
- It’s hands-off after a quick sear. You brown the chicken for a few minutes, then the slow cooker does the actual cooking while you get on with your day.
- One pound of chicken stretches to four servings. The mushrooms and sauce round out the plate, so a modest amount of chicken and a quarter cup of cream cover four dinners.
- It uses pantry seasonings. Paprika, garlic powder, and a few cloves of garlic do most of the flavoring, so there’s no special shopping trip.
- The sauce is a homemade take on creamy Italian chicken. A little sweet Marsala and mushrooms give you the kind of saucy chicken you might otherwise order out, made in your own kitchen.
- It’s thickened with cornstarch, not flour. That keeps the dish gluten-free and gives the sauce a clean, glossy finish.
- Leftovers reheat well. The chicken and sauce hold up for a few days, which makes this a useful one to cook for weekday lunches.
Ingredients You’ll Need
Here’s what’s worth knowing before you start; the printable card below has the full list with quantities.
- Boneless skinless chicken breasts. Slice each breast in half horizontally so the pieces are an even thickness, which stops the thick end from staying underdone while the thin end overcooks. You’ll sometimes see these sold as chicken supremes at the meat counter; one pound covers four servings here.
- Sweet Marsala wine. This is what gives the sauce its slightly sweet, nutty flavor. Dry Marsala works in a pinch, but skip anything labeled cooking wine, since the sauce tastes only as good as the Marsala you use.
- Mushrooms. Two cups looks like a lot, but they shrink right down and add body to the sauce. Sliced white or cremini both work.
- Heavy cream. Just a quarter cup, stirred in at the end. It softens the Marsala and pulls the sauce together without making it heavy.
- Cornstarch. Whisked with cold water into a slurry, it thickens the sauce to a spoon-coating consistency and keeps the dish gluten-free.
- Low-sodium chicken broth. It stretches the braising liquid so there’s enough sauce to go around. If you’d rather, you can use a little more Marsala in its place.
How to Make Slow Cooker Chicken Breast
The full printable recipe with US and metric measurements is in the card below. Here’s how it comes together.
Sear the chicken first
Season the chicken all over with paprika, garlic powder, salt, and pepper. Heat the olive oil in a skillet over medium-high heat and sear the pieces for 2 to 3 minutes per side, just until lightly browned.
You’re not cooking them through here, only building the browning that the slow cooker can’t give you on its own.
Cook it low and slow
Transfer the chicken to the slow cooker and add the mushrooms, minced garlic, Marsala, and broth. Cover and cook on low for about two hours, until the chicken is tender and reaches 165°F (74°C) at its thickest point.
A thermometer beats the clock here, because lean breast meat turns from tender to stringy quickly once it goes past done.
Thicken the sauce
Turn the cooker up to high. Whisk the cornstarch with cold water in a small bowl until smooth, then stir the slurry into the liquid and cook for about 10 minutes, until the sauce thickens enough to coat a spoon.
Finish with the cream
Lift the chicken out for a moment and stir the heavy cream into the sauce until smooth. Serve the chicken with the sauce and garnish with fresh parsley or thyme before serving.
Recipe Notes and Expert Tips
- Match the cooker to the amount of chicken. A single pound in a large slow cooker heats fast and overcooks easily, so use your smallest cooker for this or check the chicken at the two-hour mark rather than leaving it longer by default.
- Pull it at temperature, not by the clock. Take the chicken to 165°F (74°C) and stop there. Leaving it on the warm setting for another hour is the fastest way to dry, stringy breast meat.
- Don’t skip the sear. Those two to three minutes per side add a browned, savory layer you can’t get from the slow cooker alone, and it’s worth the extra pan to wash.
- Make the slurry with cold water. Cold water lets the cornstarch disperse before it hits the hot liquid. Stirred in dry, it clumps into lumps that are hard to break up.
- Add the cream off the heat. Stirring it in after you lift the chicken out, away from the cooker’s direct heat, keeps the cream from splitting or turning grainy.
Recipe Variations
- Use dry Marsala. If dry is what you have, it works fine. I’ve tested it that way, and the sauce comes out a little less sweet but still savory and good.
- Leave the wine out. To cook without Marsala, use all low-sodium chicken broth instead. The sauce turns more savory than sweet, and since the card already offers broth in place of the wine, it’s a supported swap that doesn’t change the timing.
- Swap in chicken thighs. Boneless thighs are more forgiving and stay juicier, though I haven’t tested them in this exact recipe. They run a little fattier and usually need longer to cook through, so go by the thermometer rather than the clock.
How to Store Leftovers
Get the chicken and sauce into the fridge within 2 hours of cooking rather than leaving the pot out to cool on the counter. In an airtight container, leftovers keep for 3 to 4 days, or freeze them for up to 3 months.
Warm leftovers on the stovetop over low heat to keep the cream sauce smooth. The sauce may look slightly separated after freezing; a low, slow warm-up with a good stir will bring it back together. It should reach 165°F (74°C) before serving.
To get ahead the night before, sear the chicken and slice the mushrooms a day early. Keep them covered in the fridge; load the slow cooker in the morning. Cool the cooked dish in the fridge before freezing; this keeps the sauce texture smoother after thawing.
What to Serve With Slow Cooker Chicken Breast
This is a saucy dish, so I serve it over something that catches the sauce. Egg noodles or plain rice do the job on a weeknight, and a batch of creamy mashed potatoes turns it into more of a Sunday plate. To keep the meal from feeling heavy, add a green vegetable or a crisp salad on the side. That’s usually all it needs.
FAQs
No, thaw it first. Food-safety guidance from the USDA is clear that you should not cook frozen chicken in a slow cooker, because the cooker heats gradually and frozen meat spends too long in the temperature range where bacteria multiply before it comes up to a safe heat. Thaw the breasts in the fridge overnight, or use a cold-water thaw, then sear and cook them as written.
Curdling usually means the cream went in too early or over high heat. The fix is to take the chicken out first and add the cream at the very end, once things have come off the boil. Reheat any leftovers slowly, over low heat, for the same reason.
Overcooking is almost always the cause. Lean breast has little fat to fall back on, so once it passes done it goes stringy fast. Cooking it just until it reaches temperature, then serving it promptly, is what keeps it juicy.
Yes. Use all low-sodium chicken broth in place of the wine. You’ll lose the sweet, nutty note the Marsala brings, but the sauce is still savory and works on a weeknight.
More Slow Cooker Dinners I Keep in Rotation
If this one went well, here are a few more hands-off slow cooker dinners I come back to.
- Slow Cooker Ranch Chicken. When I want another dump-and-go chicken night, this one brings potatoes and carrots along, so it’s a whole dinner in one pot.
- Slow Cooker Pork Carnitas. For a night I’ve got a little more time, the sear-then-broil finish gives you crispy edges you don’t get from plain shredded pork.
- Slow Cooker Pot Roast. My pick when I’m feeding a crowd; one chuck roast and the vegetables cook down into a full Sunday dinner.
- Slow Cooker Taco Meatloaf. When the kids want something a bit different, the crushed nacho chips baked into this one make it the fun option.
- Slow Cooker Nacho Meatballs. The one I make for game day, since it works as an appetizer or spooned over rice for dinner.

Notes
- Slice each breast in half horizontally so it cooks evenly and the thick end does not stay underdone.
- Sear the chicken 2 to 3 minutes per side before it goes in; the browning adds flavor that the slow cooker cannot.
- Use sweet Marsala for a slightly sweet, nutty sauce; dry Marsala works in a pinch, but skip cooking wine.
- Whisk the cornstarch with cold water before adding it, or it clumps in the hot liquid.
- Lift the chicken out and stir the cream in off the direct heat so it does not curdle.
- Cool the dish completely in the fridge before freezing so the sauce texture stays smoother after thawing.
- Reheat leftovers gently on the stovetop over low heat so the cream sauce stays smooth.
