First things first, shred that beautiful rotisserie chicken. I usually do this while it's still a bit warm, it's easier. Then, get your veggies ready. Dice your onion – try not to cry, hon! – and mince that garlic. You want everything prepped and ready to go before you even think about turning on the stove. This is where I always forget to take the chicken off the bone, oops! It's worth the little bit of effort for a smooth cooking process.

Heat a large oven-safe skillet over medium heat with a splash of olive oil. Add your diced onion and let it soften, about 5-7 minutes, until it's translucent and smelling sweet. Then, toss in the minced garlic for just a minute or so, until it's fragrant. Don't let it burn, that's a mistake I've made too many times, and it makes everything bitter, ugh! This step is key for building flavor for your Rotisserie Chicken Shepherd's Pie.

Sprinkle the flour over the onions and garlic, stirring constantly for about a minute. This creates a roux, a fancy word for a thickener. Slowly whisk in the chicken broth and milk, stirring until the sauce starts to thicken and smooth out. Add the Worcestershire sauce, salt, and pepper. Stir in the shredded rotisserie chicken and frozen mixed vegetables. Let it simmer gently for 5-7 minutes, until the sauce is bubbly and the veggies are tender. It should smell absolutely divine now! This is the heart of your Rotisserie Chicken Shepherd's Pie.

While your filling simmers, get those potatoes peeled and chopped into even chunks. Boil them in salted water until they're fork-tender, about 15-20 minutes. Drain them really well – no watery mash, please! Mash them with plenty of butter, heavy cream (or milk), and a good pinch of salt and pepper until smooth and fluffy. I like mine with a few small lumps, honestly, it adds character! Don't overmix, or they'll get gluey, a mistake I learned the hard way.

Pour the chicken and vegetable filling into your oven-safe skillet (if it's not oven-safe, transfer it to a 9x13 inch baking dish). Spread the mashed potatoes evenly over the top of the filling. You can use a fork to create little peaks and valleys, which get wonderfully crispy. Sprinkle that sharp cheddar cheese generously over the potatoes. This is the fun part, making it look pretty, even if it's a bit messy, that's okay! A little kitchen chaos is part of the charm.

Pop your Rotisserie Chicken Shepherd's Pie into a preheated oven at 375°F (190°C) for 25-30 minutes, or until the filling is bubbling around the edges and the mashed potato topping is golden brown and crispy. If you want extra color, you can even broil it for a minute or two at the very end, but watch it like a hawk! Let it rest for 10 minutes before serving. It's hard, but trust me, it helps it set and keeps all that deliciousness together.
