Step 1:

Place a large frying pan over medium-high heat and pour some oil. Once the oil is hot, add the chicken thighs and cook until lightly brown on both sides for about 5 minutes. After that, remove them from the pan and place them in the slow cooker.

Step 2:

Add the butter to the pan and let it melt. Once melted, add the onion and saute for about 5 minutes until softened while stirring occasionally.

Step 3:

Add the garlic and cook for another minute. Next, stir in the flour, salt, pepper, thyme, and celery salt. Let it cook for about 2 minutes. Pour in the stock and lemon juice. Stir and let it come to a boil, then pour into the slow cooker over the chicken.
