The cooking time will vary slightly based on the size of the chicken breasts, but do not overcook them or they’ll be dry.
Try serving on soft burger buns to make Mississippi chicken sandwiches, or rolled in tortillas with yellow rice.  The chicken has a lot of flavor and does well paired with something plain.

I love making things from scratch but there’s no need to be snobby about seasoning packets. There’s a time and a place for super easy recipes. This is a go-to dinner when I’m feeling drained and don’t have the energy for a lot of work.

You’ll need the following for this simple slow cooker meal:

  • Ranch seasoning mix. This blend of herbs and spices can typically be found in the spice aisle or with the salad dressings. It infuses the chicken with a tangy, herby flavor that’s hard to replicate, but in a pinch, a combination of dried parsley, dill, garlic powder, and onion powder can be used.
  • Au jus seasoning mix. Located near the gravy mixes or soup stocks, this savory ingredient adds a depth of flavor to meats that is both rich and comforting. If you’re out, mixing beef bouillon with a dash of soy sauce and a sprinkle of garlic and onion powders can offer a similar umami-rich profile.
  • Pickled pepperoncini peppers. You’ll find these tangy, mildly spicy peppers in the pickle aisle, and they add a bright, zesty kick to the dish. If pepperoncini isn’t your style or you can’t find them, banana peppers make a great substitute without losing the dish’s characteristic zip.

If you don’t have seasoning packets, you can makke your own. To be clear, I would never (NEVER!) o this! The whole point of this recipe is how easy is it. But just in case, here you go 😉:

Homemade Ranch Seasoning Mix:

  • 1 tablespoon dried parsley
  • 1 teaspoon dried dill
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon dried basil
  • 1/2 teaspoon pepper

Simply mix these spices together and use in place of a packet of ranch seasoning mix.

Homemade Au Jus Seasoning Mix:

  • 2 teaspoons beef bouillon granules or 1 cube crushed
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon garlic powder
  • A pinch of black pepper
  • A pinch of salt (optional, depending on the saltiness of your bouillon)
  • 1/2 teaspoon soy sauce or Worcestershire sauce (to be added to the liquid in the recipe)

Combine the dry ingredients and use as a substitute for one packet of au jus mix. Remember to add the soy sauce or Worcestershire sauce to the cooking liquid to fully replicate the depth of flavor found in au jus mixes.

  • Slow cooker. The cornerstone of this recipe, a slow cooker allows the chicken and seasonings to meld over several hours, resulting in tender, flavorful meat that practically falls apart.
  • Large spoon or spatula. Essential for mixing the ingredients without making a mess and for serving the finished dish, a sturdy spoon or spatula will ensure you can scoop out every delicious bite.
  • Meat thermometer. To guarantee that your chicken is cooked safely and to perfection, a meat thermometer is a must; it removes all guesswork, ensuring the internal temperature is just right.
  • Cooking spray. A quick spritz inside the slow cooker before adding your ingredients helps prevent sticking, making cleanup a breeze.

🔍 FAQs

Do you need to chop or pre-cook the chicken?

Absolutely not. The whole point of this recipe is to be easy! 😊

Should I use fresh or frozen chicken breasts?

Either will work just fine. If you use frozen, just make sure they are thawed before adding them to the slow cooker.

👩🏻‍🍳 Expert tips

  • Choosing the Right Chicken. Opt for chicken breasts that are roughly the same size to promote even cooking. If the breasts are thick, consider butterflying them for more uniform thickness and better seasoning coverage.
  • Layering Ingredients. When adding your ingredients to the slow cooker, place the chicken at the bottom so it’s directly in the heat. Then, add your seasonings before the butter and peppers to allow the spices to seep into the meat as it cooks.
  • Managing Moisture. If you prefer a thicker sauce, remove the cooked chicken at the end, and set the slow cooker to high with the lid off. Mix a tablespoon of cornstarch with water and stir it into the juices to thicken.
  • Balancing Flavors. Seasoning packets can vary in saltiness. If you’re sensitive to salt or using homemade seasonings, start with less. Taste as you go, and adjust accordingly before serving.
  • Serving Suggestions. If serving with noodles or potatoes, use some of the cooking liquid to flavor them.
  • Utilizing Leftovers. Shred any leftover chicken and use it as a filling for tacos, sandwiches, or as a protein boost for salads.
  • Slow Cooker Care. To prevent cracking your ceramic slow cooker insert, always allow it to reach room temperature before cleaning it. This is especially important if using cold water.

  1. 5 stars
    This recipe is one of my go to’s. It works equally well with chicken, beef or pork roast. Especially delish served with rice and the yummy gravy. I have substituted pickled Jalapenos when pepperoncini peppers weren’t available, made this gluten free with gf gravy packet and have added veggies to the roast, like potatoes and carrots. Just a terrific recipe to have in your kitchen recipe arsenal.

  2. Hi Katie, could you cook this in the slow cooker on high for 2-3 hours instead of on low for 4-5, also can you omit the peppers all together?
    Thank you 🙂
