Ingredients You’ll Need

Chicken

2 to 2.5 pounds boneless skinless chicken breasts
- Slice large pieces in half horizontally so they cook evenly.
- You can swap with boneless skinless chicken thighs if you like darker meat and extra tenderness.

Creamy garlic parmesan sauce

1 cup heavy cream
- Use full-fat for the best thick, silky sauce.
- You can use half-and-half, but the sauce turns slightly thinner.
1 cup low-sodium chicken broth
- Low-sodium broth gives you more control over salt.
- Use a good-tasting brand like Swanson or Kitchen Basics.
4 ounces cream cheese, softened and cubed
- Use full-fat for richer flavor and better melting.
- Neufchâtel works if you want a slightly lighter version.
¾ to 1 cup freshly grated Parmesan cheese
- Freshly grated melts smoother than the green can.
- Use a block of Parmigiano Reggiano or a good domestic parmesan.
6 to 8 cloves garlic, minced or pressed
- Jarred minced garlic works in a pinch, but fresh gives better flavor.
- If you use jarred, use a heaping tablespoon.
1 teaspoon onion powder
1 teaspoon Italian seasoning
½ teaspoon dried parsley (optional, for extra color)
½ to 1 teaspoon kosher salt, to taste
½ teaspoon black pepper

To finish

1 to 2 tablespoons cornstarch mixed with 2 tablespoons cold water
- This slurry thickens the sauce at the end if you want it extra velvety.
2 tablespoons grated Parmesan, for topping
Fresh parsley or basil, chopped, for garnish

Optional add-ins

1 to 2 cups baby spinach
- Stir in during the last 15 minutes so it wilts but stays bright.
1 cup sliced mushrooms
- Add at the beginning if you like extra savory flavor.
½ cup sun-dried tomatoes, chopped
- Use the kind packed in oil, drained lightly.

Equipment

4 to 6 quart slow cooker or Crockpot
Cutting board and sharp knife
Measuring cups and spoons
Small whisk or fork for the cornstarch slurry
Tongs or a spatula to handle the chicken

Tips & Tricks

Brown the chicken in a skillet for 2 to 3 minutes per side if you want extra flavor and color, though the recipe still tastes great without this step.
Use room temperature cream cheese so it melts smoothly and does not clump in the sauce.
Grate the Parmesan from a block, since pre-shredded cheese often contains anti-caking agents that keep it from melting nicely.
Taste the sauce near the end of cooking and adjust salt and pepper, since different broths and cheeses vary in saltiness.
Keep the lid on the slow cooker as much as possible, since frequent peeking drops the temperature and stretches the cook time.
Add spinach or other delicate veggies near the end so they stay bright and do not overcook.
Thicken the sauce with a cornstarch slurry only if you want it extra thick; skip it if you prefer a looser sauce for rice.
Shred the chicken right in the slow cooker if you want a saucy, shredded style that coats pasta or mashed potatoes beautifully.

How to Make Crockpot Creamy Garlic Parmesan Chicken Recipe

Step 1: Prep the chicken

Pat the chicken breasts dry with paper towels so they sear and season better. Trim any excess fat. If the pieces look very thick, slice them in half horizontally so they cook evenly and stay tender.

Season both sides of the chicken with a light sprinkle of salt and pepper. You do not need to go heavy, since the sauce also brings plenty of flavor.

Step 2: Optional browning

Heat a tablespoon of olive oil in a skillet over medium-high heat. Add the chicken in a single layer and sear for 2 to 3 minutes per side until the outside looks lightly golden. You only want color, not fully cooked chicken.

Transfer the chicken to the slow cooker in an even layer. If you skip browning, place the seasoned raw chicken directly into the Crockpot.

Step 3: Mix the creamy garlic parmesan sauce

In a medium bowl, whisk together the heavy cream and chicken broth. Add the softened cream cheese cubes and whisk until mostly smooth; a few small bits will melt in the slow cooker. Stir in the minced garlic, Parmesan, onion powder, Italian seasoning, dried parsley, salt, and black pepper.

Taste the mixture and adjust seasoning if needed. Pour the sauce over the chicken in the slow cooker, making sure the chicken sits mostly covered.

Step 4: Slow cook the chicken

Cover the slow cooker with the lid. Cook on low for 3 to 4 hours or on high for about 2 hours, until the chicken reaches 165°F and feels tender when you pierce it with a fork. Check around the 3 hour mark on low so you do not overcook and dry out the chicken.

If you want to add mushrooms, place them on top of the chicken before you start cooking. They will soften and release flavor into the sauce.

Step 5: Add greens or extras

About 15 to 20 minutes before you plan to serve, stir in baby spinach or sun-dried tomatoes if you use them. Push them down into the sauce so they wilt and warm through. Taste the sauce again and tweak salt and pepper.

If the sauce looks thinner than you like, stir together the cornstarch and cold water in a small bowl. Pour the slurry into the slow cooker, stir, and cook for another 10 to 15 minutes until the sauce thickens.

Step 6: Shred or slice the chicken

Use tongs to transfer the chicken to a cutting board. Slice it into thick slices or shred it with two forks, depending on how you want to serve it. I like shredded chicken over pasta and sliced chicken over mashed potatoes or rice.

Return the chicken to the slow cooker and stir so every piece gets coated in the creamy garlic parmesan sauce. Sprinkle extra Parmesan and chopped fresh parsley or basil on top.

Step 7: Serve

Spoon the Crockpot Creamy Garlic Parmesan Chicken over hot cooked pasta, rice, or mashed potatoes. Ladle extra sauce over the top, since that sauce tastes like liquid gold. Add a side of steamed broccoli or green beans to balance the richness.

Serve straight from the slow cooker on warm so the sauce stays silky. Keep the lid partially on between servings to hold the heat.

What to Serve with Crockpot Creamy Garlic Parmesan Chicken Recipe

This Crockpot Creamy Garlic Parmesan Chicken Recipe pairs beautifully with pasta such as fettuccine, penne, or egg noodles. Mashed potatoes or buttery rice soak up the sauce and turn the plate into pure comfort food. Add a bright side like roasted broccoli, steamed green beans, or a crisp salad with lemony dressing to cut through the richness.

Garlic bread or warm dinner rolls also taste great, since they scoop up every last bit of sauce. If you want a lighter option, serve the chicken over zucchini noodles or spaghetti squash.

Storage Options

Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
Reheat gently on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce, and stir often so it stays creamy.
Reheat single portions in the microwave at 50 to 60 percent power in short bursts, stirring in between, until hot.
Freeze cooled chicken and sauce in freezer-safe containers or bags for up to 2 months, then thaw overnight in the fridge and reheat slowly on the stovetop.
