Ingredients

- 1 cup chicken broth
- 2 tablespoons olive oil
- 2 tablespoons butter, softened
- 1 tablespoon paprika
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary

Choosing the Best Ingredients
Choose a whole chicken that fits comfortably inside your slow cooker with the lid fully closed. A chicken between 4 and 5 pounds works well in most standard slow cookers.
Fresh garlic gives the cooking juices a deep, comforting flavor. Use plenty of garlic because it softens as the chicken cooks and becomes mild and delicious.
Chicken broth creates a savory base beneath the chicken. Use low-sodium broth if possible so you can control the final seasoning.
Dried thyme, rosemary, and Italian seasoning add a classic roast chicken flavor. Fresh herbs can also be used if you have them available.
How to Make Slow Cooker Garlic Herb Whole Chicken
Place the sliced onion in an even layer on the bottom of the slow cooker. Add half of the minced garlic and pour in the chicken broth.
Pat the chicken dry with paper towels. In a small bowl, mix the olive oil, softened butter, paprika, thyme, rosemary, Italian seasoning, garlic powder, onion powder, salt, black pepper, and remaining minced garlic.
Rub the seasoning mixture all over the outside of the chicken. Lift the skin gently if desired and rub a little seasoning underneath for even more flavor.
Place the lemon halves inside the chicken cavity if using. Set the chicken breast-side up on top of the onions in the slow cooker.
Cover with the lid and cook on low for 6 to 7 hours or on high for 4 to 5 hours. The chicken is ready when the thickest part of the thigh reaches 165°F.
Carefully remove the chicken from the slow cooker using large spatulas or tongs. Let it rest for 10 minutes before carving.
Spoon some of the garlic herb juices and onions from the slow cooker over the chicken. Sprinkle with fresh parsley before serving if desired.
How to Make the Skin Golden
A slow cooker makes the chicken tender and juicy, but the skin stays soft. If you would like a golden finish, place the cooked chicken on a baking sheet.
Brush it lightly with some of the slow cooker juices. Broil for 3 to 5 minutes, watching closely, until the skin becomes lightly browned and crisp around the edges.
This extra step is optional, but it gives the chicken a beautiful roasted appearance for serving.
Tips for the Best Slow Cooker Chicken
Place the chicken on top of the onions instead of directly in the broth. This helps it cook evenly and allows the flavorful juices to circulate underneath.
Use a meat thermometer to check the chicken. The thickest part of the thigh should reach 165°F before serving.
Let the chicken rest before carving. This gives the juices time to settle into the meat and makes the chicken easier to cut.
Save the cooking juices. They are full of garlic, herbs, and chicken flavor and can be spooned over rice, potatoes, or vegetables.
Easy Variations
For lemon herb chicken, use the lemon inside the chicken and add extra fresh thyme or rosemary.
For a smoky version, add 1 teaspoon smoked paprika and a small pinch of cayenne pepper.
For a buttery garlic chicken, add an extra tablespoon of softened butter to the seasoning mixture.
For a Mediterranean-style chicken, add sliced olives, oregano, lemon, and a few cherry tomatoes to the slow cooker.
For a sweeter herb chicken, add 1 tablespoon honey to the butter and olive oil mixture before rubbing it over the chicken.
What to Serve with Slow Cooker Whole Chicken
This chicken is delicious with creamy mashed potatoes, roasted potatoes, rice, or buttered noodles. Spoon the warm garlic herb juices over the side dish for extra flavor.
Serve it with roasted carrots, green beans, broccoli, corn, or a simple green salad for a balanced family dinner.
Crusty bread or dinner rolls are also perfect for soaking up the flavorful broth from the slow cooker.
Make-Ahead Instructions
You can prepare the onion, garlic, broth, and seasoning mixture one day ahead. Keep everything covered in the refrigerator until you are ready to cook.
For an easy morning start, season the chicken the night before and refrigerate it in a covered dish. In the morning, place the ingredients in the slow cooker and begin cooking.
This recipe is great for busy days because dinner is mostly ready by the time you come home.
Storing Leftovers
Remove the chicken meat from the bones and store it in an airtight container with a few spoonfuls of the cooking juices.
Keep leftovers in the refrigerator for up to four days. Reheat gently in the microwave, skillet, or oven until hot.
Use leftover chicken in sandwiches, wraps, chicken salad, tacos, soups, pasta dishes, and casseroles.
Can You Freeze It?
Yes. Shred or chop the leftover chicken and place it in freezer-safe containers or bags with a little cooking juice.
Freeze for up to three months. Thaw overnight in the refrigerator, then reheat gently for easy meals.
Frozen slow cooker chicken is especially helpful for quick weeknight soups, sandwiches, and casseroles.
Common Mistakes to Avoid
Do not add too much broth. The chicken naturally releases juices as it cooks, so one cup is enough for a flavorful sauce.
Avoid opening the slow cooker lid often. Each time the lid is lifted, heat escapes and can add extra cooking time.
Do not carve the chicken immediately after cooking. A short resting time helps keep the meat juicy.
Make sure the chicken fits comfortably in the slow cooker. The lid should close completely for even cooking.
Frequently Asked Questions
Can I use frozen chicken?
For the most reliable results, use a fully thawed whole chicken. It will cook more evenly and be easier to season.
Can I cook vegetables with the chicken?
Yes. Add chopped carrots, potatoes, celery, or small onions beneath the chicken. The vegetables will absorb the flavorful juices as they cook.
What size slow cooker do I need?
A 6-quart slow cooker works well for a 4- to 5-pound chicken. Use a larger slow cooker for a bigger bird.
Can I use boneless chicken instead?
Yes. Chicken thighs or breasts can be used, but they will cook faster than a whole chicken. Check them earlier and cook until they reach 165°F.
What can I do with the bones?
Use the bones and leftover cooking juices to make a simple homemade chicken broth. Simmer them with water, onion, celery, and carrots for a flavorful stock.
