Ingredients You’ll Need for Slow Cooker Garlic Butter Chicken

When it comes to making slow cooker garlic butter chicken, the ingredients are simple, familiar, and probably already waiting in your kitchen. Each one plays an important role in creating that buttery, garlicky flavor that makes this dish so comforting. Here’s a closer look at what you’ll need:

  • Chicken Breasts (4 pieces, about 1.5 pounds)
    Boneless, skinless chicken breasts are the star of the show. They stay tender and juicy as they cook low and slow, soaking up all that buttery garlic flavor. If you prefer, you can swap them out for boneless chicken thighs, which offer even more richness.
  • Unsalted Butter (½ cup, or 1 stick)
    Butter is the heart of this dish. It creates a silky sauce that coats every bite of chicken, carrying the garlic and spices beautifully. Use unsalted butter so you can better control the seasoning.
  • Garlic (6 cloves, minced)
    The name says it all—garlic is essential here. Freshly minced garlic gives the sauce its bold, savory punch. Don’t be shy with the garlic; this recipe was made for garlic lovers.
  • Onion Powder (1 teaspoon)
    A pantry staple that adds depth and a subtle sweetness to balance the savory flavors.
  • Smoked Paprika (1 teaspoon)
    This spice gives a warm, smoky undertone that makes the chicken taste like it simmered over a wood fire. Regular paprika works too, but smoked paprika takes it to another level.
  • Italian Seasoning (1 teaspoon)
    A blend of herbs like oregano, basil, thyme, and rosemary adds just the right amount of earthy flavor. It ties the butter and garlic together perfectly.
  • Salt and Black Pepper (to taste)
    Simple but essential. They season the chicken inside and out, making sure each bite is balanced.
  • Lemon Juice (from 1 fresh lemon)
    A squeeze of lemon juice brightens up the rich garlic butter sauce, keeping the dish from feeling too heavy. That little zing of citrus is what makes this recipe taste fresh and lively.
  • Fresh Parsley (1 tablespoon, chopped, for garnish)
    A sprinkle of parsley at the end adds color, freshness, and just a hint of herbal flavor. It’s the finishing touch that makes your plate look and taste restaurant-worthy.

How to Make Slow Cooker Garlic Butter Chicken (Step by Step)

Making slow cooker garlic butter chicken is one of the easiest and most rewarding things you can do on a busy weeknight. You’ll spend just a few minutes prepping, and then your slow cooker will do all the heavy lifting while your kitchen fills with that incredible buttery garlic aroma. Let’s walk through it step by step:

Step 1: Prepare the Garlic Butter Sauce

Start by melting the butter in a small microwave-safe bowl or on the stovetop. Once melted, stir in the minced garlic, onion powder, smoked paprika, Italian seasoning, salt, and pepper. This flavorful mixture is what transforms simple chicken into a savory, comforting dish. Think of it as liquid gold—it’s the heart of your slow cooker garlic butter chicken.

Step 2: Arrange the Chicken in the Slow Cooker

Place the chicken breasts directly into your slow cooker. Don’t worry about browning them first—this recipe is all about simplicity. Arrange them in an even layer so each piece gets coated with the sauce.

Step 3: Pour on the Garlic Butter Mixture

Slowly drizzle the garlic butter mixture over the chicken, making sure every breast is fully coated. Use the back of a spoon to spread it if needed. This step ensures that the flavor seeps into the chicken as it cooks low and slow.

Step 4: Add Fresh Lemon Juice

Squeeze the juice of one lemon over the chicken. The lemon adds brightness and helps balance the richness of the butter. It might seem like a small step, but it makes a huge difference in flavor.

Step 5: Set It and Forget It

Cover the slow cooker with the lid and set it to cook on low for 6 hours. During this time, the chicken will gently cook in the garlic butter sauce until it’s tender, juicy, and infused with flavor. This is the beauty of slow cooker garlic butter chicken—you can go about your day while dinner takes care of itself.

Step 6: Finish and Garnish

Once the cooking time is up, carefully remove the chicken using tongs. You can serve the breasts whole for a classic look, or shred them if you prefer a more rustic presentation. Spoon some of the rich garlic butter sauce over the top and garnish with freshly chopped parsley.

Step 7: Serve with Comforting Sides

This dish pairs perfectly with mashed potatoes or fluffy rice—both soak up the sauce beautifully.

It’s another slow cooker favorite that fits right in with the same cozy, family-style vibe.

Tips and Tricks for Perfect Slow Cooker Garlic Butter Chicken

  • Don’t skip the lemon. It cuts the richness beautifully.
  • Double up! You can easily double this recipe for a crowd—just don’t overpack the slow cooker.
  • For creamier sauce, stir in a splash of heavy cream at the end.
  • Storage hack: Shred leftovers and use them in wraps or over pasta the next day.

Storage

Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently on the stove with a splash of chicken broth (or water) to keep it juicy.

FAQs

Yes! Boneless thighs work beautifully and stay extra tender.
