Method
- Pat chicken breasts dry and pound to even thickness (about 3/4 inch throughout). Season both sides generously with salt and black pepper. Lightly dredge in flour, shaking off excess.
- Heat olive oil in a large skillet over medium-high heat until shimmering. Sear floured chicken for 3-4 minutes per side until golden-brown. Chicken doesn't need to be cooked through. Transfer to slow cooker.
- In the same skillet with remaining oil and browned bits, add sliced mushrooms, diced shallot, and minced garlic. Add more oil if pan looks dry. Sauté for 5-8 minutes, stirring occasionally, until mushrooms release liquid, it evaporates, and mushrooms turn golden brown. Shallot should be translucent and garlic fragrant.
- Pour Marsala wine into skillet with mushroom mixture. Scrape up all browned bits from bottom of pan using a wooden spoon. Let wine simmer for 2-3 minutes to reduce slightly.
- Pour mushroom and wine mixture over chicken in slow cooker. Add chicken broth, fresh thyme sprigs, and bay leaves. Stir gently to distribute liquid and mushrooms.
- Cover and cook on Low for 4-5 hours or High for 2-3 hours until chicken reaches 165°F and is tender enough to cut easily with a fork.
- Remove chicken and place on a plate. Fish out and discard thyme sprigs and bay leaves. Whisk heavy cream into sauce. For thicker sauce, stir in cornstarch slurry and cook on High for 10-15 minutes until thickened.
- Return chicken to slow cooker and turn in sauce to coat completely. Serve hot, spooning extra sauce and mushrooms over each portion. Garnish with fresh thyme if desired.
Notes
Storage: Store chicken and sauce together in airtight container for up to 4 days. Sauce thickens in refrigerator—add broth or cream when reheating. Searing importance: Don't skip the searing and sautéing—these steps create caramelized flavors that can't be achieved by slow cooking alone. Wine substitute: Dry white wine or dry sherry work but won't have Marsala's unique sweet-nutty quality. White wine with 1 tbsp balsamic vinegar gets closer. Chicken thighs: More forgiving than breasts. Check at 4 hours on Low. Cream tip: Add at end to prevent curdling. Never add to boiling liquid. Lighter: Use half-and-half instead of heavy cream. Make-ahead: Sear and sauté night before, refrigerate, assemble in morning.
