Place the chicken breasts in the bottom of your slow cooker.
Pour the chicken broth over the chicken, making sure it’s nearly covered.
Add the cream of chicken soup, garlic powder, onion powder, and a pinch of salt and pepper. Stir gently to combine.
Cover the slow cooker and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is tender and easily shredded.
Using two forks, shred the chicken directly in the slow cooker.
Stir in the egg noodles, butter, and heavy cream, making sure the noodles are submerged in the liquid.
Cover and cook on high for 30-40 minutes, stirring occasionally, until the noodles are tender but still slightly firm (al dente).
If using, add the frozen peas and cook for an additional 5 minutes until warmed through.
Taste and adjust seasoning with salt and pepper as needed.
Serve warm, enjoying the creamy, comforting goodness of homemade Amish-style chicken and noodles.
Enjoy!
