Slow cooker Chicken and Mushroom Alfredo fills your home with the most comforting aroma by dinnertime. This creamy pasta dish stands up to any fancy Italian restaurant plate but comes together with minimal fuss and everyday good ingredients.
The first time I made this was for a birthday dinner at home and it was such a hit the leftovers barely made it to the fridge. I now keep the canned soup and a block of cream cheese on standby because it is always a family favorite.
Ingredients
- Bone in chicken breast halves: I like these for their better flavor and juiciness in the slow cooker Compare for ones that are plump and pink with no extra liquid in the package
- Canola oil: This helps the chicken brown and adds a light richness Pick a fresh oil without off smells
- Condensed cream of chicken soup: Forms the creamy sauce base and boosts savory flavor Choose a lower sodium version if desired
- Condensed cream of mushroom soup: Adds earthiness and even more body to the sauce If you can get it look for one with big mushroom pieces
- Chicken broth: Helps loosen and build the sauce so it coats the noodles well Go for low sodium if you want more control
- Small onion: Chopped small so it melts right in Choose a firm onion without soft spots
- Jarred sliced mushrooms: Provides consistent texture and saves time Check for a good best by date so they are not mushy
- Garlic salt and black pepper: These simple seasonings keep the flavors balanced
- Fettuccine: The classic wide noodle catches all the sauce Cook al dente and avoid mushy pasta by checking early
- Cream cheese: This is the secret for that rich velvet sauce Use a block form and let it soften for easy blending
- Shredded Parmesan cheese: For topping if you like a sharp salty bite Use a wedge and grate it yourself for best flavor
Instructions
- Brown the Chicken:
- In a large skillet heat the canola oil over medium high until it shimmers Add the chicken breast halves a couple at a time and cook until both sides are golden brown about four minutes per side This helps lock in juices and build flavor in the finished dish
- Load the Slow Cooker:
- Transfer the browned chicken to your slow cooker laying the pieces in a single layer to ensure even cooking
- Mix Sauce Ingredients:
- In a large mixing bowl add the condensed cream of chicken soup condensed cream of mushroom soup chicken broth chopped onion drained mushrooms garlic salt and pepper Stir until completely blended then pour the mixture over the chicken pieces in the slow cooker making sure all pieces are covered
- Slow Cook:
- Cover the slow cooker and set to low Let the chicken cook undisturbed for four to five hours or until the meat is fall off the bone tender
- Cook the Pasta:
- About twenty minutes before serving bring a large pot of salted water to a boil Add the fettuccine and cook per package instructions until just al dente Drain well so the pasta does not dilute the sauce
- Finish the Sauce:
- When the chicken is done cooking remove it gently and set aside on a plate Turn off the slow cooker Whisk the cubed cream cheese into the hot sauce in the cooker until completely melted and velvety smooth
- Serve:
- Heap the hot drained pasta onto plates Top with the tender chicken Pieces then generously ladle the rich mushroom Alfredo sauce over everything If you love extra cheese sprinkle with shredded Parmesan before bringing the plate to the table

My favorite part of this dish is the velvety sauce that comes together when cream cheese meets the slow cooked chicken juices. The first bite always takes me back to a snowy night when we gathered around the table all cozy and warm sharing a big family style plate.
Storage tips
Leftovers cool down well and can be kept in an airtight container in the fridge for up to three days. For best results reheat gently on the stovetop with a splash of milk or broth to refresh the sauce.
Ingredient substitutions
If you prefer boneless chicken thighs those are equally delicious and extra tender after slow cooking. Fresh mushrooms work in place of jarred just cook them a bit to remove some moisture before adding. You can swap in penne or linguine if fettuccine is not in the pantry.
Serving suggestions
Serve with a simple green salad and a wedge of lemon on the side for freshness. Garlic bread is always welcomed at my table. A light vegetable like steamed broccoli makes this a complete meal.
Cultural and historical context
Alfredo sauce was first born in Rome as a simple butter and parmesan creation. Our household version uses pantry shortcuts and cream cheese for comfort and convenience. I love how this recipe bridges quick home cooking with an Italian American classic.

If you have not had homemade Alfredo from the slow cooker this is your sign to try it The hands off approach makes it perfect for busy days and the result truly feels like a restaurant dinner right at home
