This Garlic Mashed Potato Chicken Bake gives you a full holiday dinner in one dish, minus the chaos of juggling ten pans.
You don’t need fancy gadgets or chef skills—just a casserole dish, an oven that (mostly) works, and the willpower not to eat all the mashed potatoes before it’s time. It keeps things simple, hearty, and perfect for feeding a crowd without turning your kitchen into a disaster zone.
With creamy potatoes, tender chicken, and golden baked goodness, this dish checks every comfort food box. It’s the kind of meal that makes everyone at the table pause mid-bite, and honestly, that might be the real Thanksgiving miracle.
Equipment
You don’t need a professional kitchen to pull this off. But you do need a few trusty tools—think of them as your Thanksgiving sidekicks.
Essentials:
- 9×13 baking dish (your stage for the casserole magic)
- Large mixing bowls (because potatoes don’t mash themselves)
- Potato masher or hand mixer (your arm workout for the day)
A sturdy cutting board and sharp knife will help you slice chicken and garlic without making it a struggle. Keep a whisk handy for blending sauces. Don’t forget oven mitts—unless you’re into mild hand burns.
| Tool | Why You Need It |

| Baking dish | Holds everything together |
| Masher | Smooth potatoes, less drama |
| Mixing bowls | Keep ingredients from staging a coup |
