This cheesy roasted garlic scalloped potatoes recipe is an excellent choice for adding a rich, comforting side dish to your Thanksgiving meal. The combination of three cheeses—sharp cheddar, mozzarella, and gouda—gives the dish a perfect balance of sharpness, creaminess, and meltiness, which elevates the classic scalloped potatoes to a gourmet level. Using roasted garlic adds a subtle sweetness and depth of flavor, amplifying the savory taste without overpowering the delicate texture of the potatoes. Incorporating a shallot provides a gentle aromatic note that complements the richness of the cheeses and cream base. The recipe calls for a simple but effective cream sauce made with unsalted butter, flour, heavy cream, and whole milk, creating a smooth and velvety texture that coats the thin slices of russet potatoes perfectly. The 45 minutes covered baking allows the potatoes to cook through evenly while bonding with the cheesy sauce. Removing the cover for an additional 30 minutes encourages a golden-brown crust to form on top. To enhance the flavor profile, a blend of seasonings—including onion powder, paprika, cayenne pepper, garlic powder, white pepper, and Goya Red Cap Adobo—adds layers of subtle heat and earthiness. These spices work together to enliven the dish without overwhelming it. Adding bacon bits provides a smoky and salty crunch that contrasts wonderfully with the creamy and tender potatoes. The final broil for 3 to 5 minutes melts any extra cheese on top and crisps the bacon for a delightful finishing touch. For best results, use fresh high-quality cheeses and roast the garlic until it's soft and caramelized. Thinly slice the potatoes for quicker cooking and even layering. This dish can be prepared a day ahead and reheated, allowing the flavors to meld beautifully. Overall, this scalloped potato recipe is practical, flavorful, and visually appealing—making it an ideal addition to your Thanksgiving essentials list and suitable for any festive occasion requiring a standout side dish.
