A flavorful and tender chicken dish slow-cooked in a rich beer and barbecue sauce blend.
Heat the canola oil in a large skillet over medium-high heat.
Ensure the oil is hot before adding the chicken to prevent sticking.
Season the chicken breasts with salt and pepper, then brown them on both sides in the skillet.
Don't overcrowd the skillet; brown the chicken in batches if necessary.
Transfer the browned chicken to the slow cooker.
Arrange the chicken in a single layer for even cooking.
Add the sliced onions to the slow cooker, spreading them over the chicken.
Slice the onions thinly for quicker cooking and better integration into the sauce.
In a mixing bowl, combine the dark beer and barbecue sauce, then pour the mixture over the chicken and onions.
Mix the sauce thoroughly to ensure even flavor distribution.
Cover the slow cooker and cook on high for 3-4 hours or on low for 7-8 hours.
Check the chicken's doneness by ensuring it reaches an internal temperature of 165°F (74°C).
Serve the chicken with the sauce spooned over it, garnished with fresh herbs if desired.
