Effortlessly elevating your kabob game starts with mastering the technique of how to cut onions for kabobs. Begin by selecting a fresh, firm onion. Slice off the top and root, then cut the onion in half. Peel the skin away and make horizontal cuts into each half without going all the way through. Next, make vertical cuts to create evenly sized onion chunks. As you slice, keep the root end intact – this will hold the onion together. Thread these carefully cut onion pieces onto your skewers with your favorite ingredients and grill to savory perfection. Your kabobs are now ready to impress!
