Slow Cooker Garlic Butter Chicken & Mushrooms

This recipe transforms simple chicken breasts and canned mushrooms into a rich, velvety dish. The slow cooking process allows the chicken to soak up the garlic-infused butter, while the mushrooms add an earthy depth and a nice texture contrast.

  • Prep time: 10 minutes

  • Cook time: 4–6 hours (Low) or 2–3 hours (High)

  • Servings: 4 people

Ingredients

  • 4 large Boneless, skinless chicken breasts

  • 2 cans (4 oz each) Sliced mushrooms, drained (or 1 lb fresh cremini mushrooms)

  • 1/2 cup Unsalted butter, sliced into pats

  • 4 cloves Garlic, minced

  • 1 tsp Dried thyme or Italian seasoning

  • 1/2 tsp Onion powder

  • Salt and Pepper to taste

  • Optional: 1/4 cup chicken broth (if you prefer more “gravy”)

  • Garnish: Fresh parsley

Instructions

  1. Layer the Chicken: Place the chicken breasts in a single layer at the bottom of the slow cooker. Season both sides generously with salt, pepper, and onion powder.

  2. Add Mushrooms: Pour the drained canned mushrooms (or fresh slices) directly over the chicken.

  3. Season & Butter: Sprinkle the minced garlic and dried herbs over the top. Place the pats of butter evenly across the chicken and mushrooms.

  4. Cook: Cover and cook on Low for 4–6 hours or High for 2–3 hours. The chicken should reach an internal temperature of 165°F (74°C).

  5. Serve: Shred the chicken slightly or serve whole, spooning the garlic butter sauce and mushrooms from the bottom of the pot over the meat.

Recipe Notes & Tips

  • Canned vs. Fresh: The image shows canned mushrooms, which are convenient and hold their shape well. If using fresh, they will release more liquid, creating a thinner but very flavorful sauce.

  • Don’t Overcook: Chicken breasts can become “woody” or dry if left on Low for more than 6 hours. Check them early!

  • Thicker Sauce: If you want a creamy gravy, stir in 2 tablespoons of heavy cream or a cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) during the last 30 minutes of cooking.

Q&A

Q: Can I use chicken thighs instead? A: Absolutely! Chicken thighs are more forgiving in the slow cooker and will stay even juicier than breasts. Cook them on Low for 5–6 hours.

Q: What should I serve this with? A: It pairs perfectly with mashed potatoes, egg noodles, or crusty bread to soak up the garlic butter. For a low-carb option, try cauliflower rice or steamed green beans.

Q: Can I freeze the leftovers? A: Yes. Store in an airtight container for up to 3 months. Thaw in the fridge overnight before reheating gently on the stovetop.
