Before you start
Before you begin, ensure your chicken thighs are trimmed of any excess fat and sliced into uniform pieces if preferred, though leaving them whole is perfectly fine for slow cooking. Mince your garlic finely to ensure its flavor permeates the entire sauce evenly.
Prepare your pasta in a separate pot of boiling salted water until it reaches an al dente consistency, then drain and set aside. Ensure your slow cooker is clean and ready for use before layering in the ingredients.
Ingredients at a glance (12)
- 2 lb boneless chicken thighs
- 1 lb thick-sliced cremini mushrooms
- 1 cup dry Marsala wine
- 1 cup beef stock
- 4 cloves garlic, minced
- 4 tbsp butter
- 8 oz cream cheese
- 1/2 cup heavy cream
- 16 oz fettuccine, cooked al dente
- 1 tsp fresh thyme
- 2 tbsp chopped parsley
- 1/4 cup shaved parmesan
Instructions
Initial layering
- Combine initial ingredientsPlace the boneless chicken thighs, thick-sliced cremini mushrooms, dry Marsala wine, beef stock, minced garlic, and butter into the slow cooker basin. Ensure the ingredients are evenly distributed to allow for uniform cooking throughout the process.Look for Ensure the lid is securely closed.Tip Layer the chicken on the bottom to ensure it stays submerged in the liquid for optimal tenderness.
At the start, the ingredients are layered neatly in the slow cooker, ready to begin the slow transformation. The mushrooms, garlic, and chicken are submerged in the liquid base, and the butter is placed on top to melt slowly as the cooker heats up, creating a fragrant base for the upcoming simmer.
Slow simmering
- Slow cook the chickenSet the slow cooker to the LOW setting and allow the mixture to cook for four hours. This slow process ensures the chicken becomes incredibly tender and the mushrooms release their deep, earthy flavor into the wine and stock base.Look for The chicken is tender and fully cooked.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid lifting the lid during the first few hours to maintain the consistent internal temperature required for safe cooking.
After four hours, the kitchen will be filled with the rich, aromatic scent of Marsala wine and savory chicken. The chicken thighs should be thoroughly cooked and tender, while the mushrooms have softened significantly, contributing their earthy essence to the dark, flavorful liquid that has developed in the slow cooker.
Final assembly
- Finish with cream and pastaOnce the four hours are complete, whisk in the cream cheese and heavy cream until the sauce is smooth and glossy. Gently toss in the pre-cooked al dente fettuccine and fresh thyme until well combined. Serve immediately topped with chopped parsley and shaved parmesan.Look for The sauce is thick, creamy, and coats the pasta perfectly.Tip If the sauce is too thick, add a tablespoon of pasta water to adjust the consistency to your preference.
The final phase brings everything together as the cream cheese and heavy cream are whisked into the sauce, creating a smooth, pale, and incredibly creamy consistency.
Once the fettuccine and fresh thyme are tossed in, the dish is ready, featuring a glossy coating on the pasta and a perfect balance of savory and creamy elements.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent even heating. Ensure all ingredients fit comfortably within the vessel. Another frequent error is using a sweet Marsala wine instead of a dry one; the sweet variety can make the final dish cloying and unbalanced.
Finally, avoid overcooking the pasta before adding it to the sauce; it should be firm enough to withstand the final toss without turning into a mushy texture.
How to tell it’s done
The chicken is done when it reaches an internal temperature of 165°F (74°C). The meat should be tender enough to shred with a fork, and the sauce should have thickened into a glossy, creamy consistency that coats the back of a spoon.
The mushrooms should be soft and fully infused with the savory Marsala wine base, providing a deep, umami flavor that defines this classic dish.
