Step 1: Prepare and Season Your Poultry
Pat the poultry completely dry with paper towels. Remove any giblets from the cavity if using a whole bird. In a small bowl, combine salt, pepper, and smoked paprika. Massage olive oil all over the poultry, then generously apply the spice mixture under the skin and inside the cavity. Let rest at room temperature for 20 minutes.
Pro tip: For maximum flavor penetration, prepare this seasoning step the night before and refrigerate uncovered for crispier skin.
Step 2: Build Your Flavor Foundation
Layer the quartered onion in the bottom of your slow cooker or Dutch oven, creating a natural rack. Scatter the smashed garlic cloves, thyme, rosemary, and bay leaves around the onion. Tuck the lemon halves alongside, cut-side up. Add optional vegetables in a single layer.
Insider trick: Sear the poultry skin-side down in a hot skillet for 3-4 minutes before slow cooking for deeper flavor.
Step 3: Add Liquid and Set Temperature
Place the seasoned poultry on top of the aromatic bed, breast-side up. In a measuring cup, combine chicken broth, white wine, and soy sauce. Pour gently around (not over) the poultry—liquid should come one-third up the sides. Set slow cooker to LOW for 6 hours or oven to 275°F if using a covered Dutch oven.
Step 4: Monitor and Baste (Optional)
Baste every 2 hours by drizzling cooking liquid over the poultry. Check liquid levels and add ½ cup warm broth if needed. Minimize lid opening to maintain temperature.
Step 5: Check Doneness and Rest
Insert an instant-read thermometer into the thickest part of the thigh—it should read 165°F for chicken or 175°F for dark meat. Transfer poultry to a cutting board and tent with foil for 10-15 minutes before carving.
Finishing touch: For crispy skin, brush with pan juices and broil on high for 3-5 minutes until golden.
