Method
Preparation
- Begin by patting the chicken breasts dry with a paper towel. Prepare your vegetables: dice the onion, slice the mushrooms, and mince the garlic for added flavor.
- (Optional) In a skillet, melt butter over medium heat and sauté the onions and mushrooms until they are softened and fragrant, about 3-5 minutes. This step deepens the flavor but can be skipped if time is tight.
- Place the chicken breasts directly into the crockpot. Pour in the chicken broth, adding in the sautéed vegetables if you chose to sauté them; otherwise, just toss them in raw.
- Stir in the Dijon mustard, Worcestershire sauce, salt, and pepper until well mixed into the broth.
Cooking
- Cover the crockpot and cook on low for 4-6 hours or on high for 2-3 hours, until the chicken is tender and easily shreds with a fork.
- About 30 minutes before you plan on serving, remove the chicken from the slow cooker and mix the flour with a bit of cold water to create a slurry. Stir this into the crockpot liquid to help thicken it further.
- Shred the chicken using two forks and reintroduce it back into the crockpot. Cook uncovered on high for an additional 20-30 minutes to allow the sauce to thicken nicely.
- Turn off the heat and gently stir in the sour cream until it’s fully incorporated. Taste and adjust seasoning if necessary. Optionally garnish with fresh parsley before serving.
Notes
Taste the broth before serving; add extra seasoning if desired, as personal preferences on salt and spice can vary. Make ahead: Prepare the chicken and sauce the night before; simply reheat once you’re ready to serve. Store leftovers in airtight containers and freeze for up to 3 months.
