Dinner Party Quality: Just 4 ingredients. It tastes so elegant, no one will believe you didn’t spend hours at the stove

Spray the inside of your slow cooker with nonstick cooking spray or lightly grease it with a bit of oil to make cleanup easier.
Place the chicken breasts in a single layer on the bottom of the slow cooker. If they’re very thick, you can slice them in half horizontally so they cook more evenly.
Scatter the sliced mushrooms evenly over the chicken.
In a medium bowl, whisk together the Marsala wine and condensed cream of mushroom soup until mostly smooth and combined. It doesn’t have to be perfect—just well mixed.
Pour the Marsala-soup mixture over the chicken and mushrooms, making sure everything is coated in the sauce.
Cover and cook on LOW for 4–6 hours or on HIGH for 2 1/2–3 1/2 hours, or until the chicken is cooked through and tender (internal temperature should reach 165°F).
Once done, taste the sauce and adjust with salt and pepper if desired. For a creamier texture, you can gently shred or slice the chicken in the slow cooker and stir it back into the sauce.
Serve the chicken and mushrooms with plenty of sauce spooned over your choice of mashed potatoes, pasta, rice, or another favorite side.
Variations & Tips
• Thicker, creamier sauce: If you like a thicker sauce, whisk 1–2 tablespoons of cornstarch with 2 tablespoons of cold water, then stir it into the slow cooker during the last 20–30 minutes of cooking. Let it cook on HIGH until slightly thickened. • Add a touch of cream: For a richer, more indulgent sauce, stir in 1/4–1/2 cup of heavy cream or half-and-half during the last 15 minutes of cooking. • Use chicken thighs: Boneless, skinless chicken thighs work beautifully here and stay extra tender. Use the same amount by weight and keep the cook time about the same. • Extra mushrooms and onions: If you love mushrooms, bump the amount up to 12–16 ounces. You can also add 1 small sliced onion to the slow cooker with the mushrooms for more flavor. • No Marsala on hand: If you can’t find Marsala wine, you can substitute with a mix of dry sherry and a splash of white wine, or even chicken broth in a pinch (just know it won’t have the classic Marsala flavor, but it will still be tasty and comforting). • Meal prep tip: This is a great make-ahead meal. You can add the chicken, mushrooms, and sauce mixture to a large freezer bag, lay it flat, and freeze. Thaw in the fridge overnight, then dump everything into the slow cooker in the morning. It also reheats well for lunches—store leftovers in an airtight container in the fridge for up to 3–4 days.
