Vegetables: use a knife and cutting board to slice any larger potatoes in halves and then give each potato a prick or 2 with a fork. Next use a vegetable peeler to peel the carrots and then chop into chunky pieces. Use a knife to slice the mini corn cobs in halves and then slice the mushrooms into halves to thin slices.
Chicken seasoning: add the chicken stock, olive oil, garlic powder, onion powder, paprika and Italian seasoning to a small glass jug then use a mini whisk to stir them till consistently combined and then set aside.
Chicken drumsticks: place the chicken legs flat on a chopping board and season them with the salt and pepper. Once done, rotate them to the other side and season this side with salt and pepper also.
Corn cobs and seasoning: next place the sliced corn cobs into the slow cooker and then pour the remaining chicken seasoning over the top. Then take a pair of tongs and gently toss to combine everything ensuring the seasoning is covering the chicken and vegetables.
Cook: now pop the lid on the slow cooker and let the dish cook for either 3 hours on high or 7 hours on low. In the final hour remove the lid and add the sliced mushrooms and then let them cook for a further hour. Once the 4 hours of cook time or 8 hours of cook time is up, you can remove the lid from the slow cooker and turn the heat off.
Air fry or grill (optional step): use a pair of tongs to remove the cooked chicken legs and place them onto a wire air fry rack or baking tray. Air fry or grill the chicken legs for 8-10 minutes to brown and crisp up the skin a little. Then return them to the slow cooker with the rest of the cooked dish.
To serve: portion the chicken legs with potatoes, carrots, corn and mushrooms into serving bowls. Drizzle a little gravy over the top and provide forks and spoons for serving. Garnish with chopped fresh parsely and a sprinkle of cracked black pepper.
