- Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic; it should just release its aroma. This is a flavor-building step that enhances the overall taste of your Cheesy Au Gratin Potatoes Recipe.
- Sprinkle the flour over the onion and garlic mixture. Cook for 1-2 minutes, stirring constantly, to create a roux. This helps to thicken the sauce and prevents it from being too runny. It’s essential for a creamy, dreamy Cheesy Au Gratin Potatoes Recipe.

Repeat this layering process two more times, ending with a layer of cheese sauce. Your Cheesy Au Gratin Potatoes Recipe should fill the kitchen with amazing aromas by now!
- Sprinkle the remaining 1 cup of shredded cheddar cheese over the top. This creates a beautiful golden crust as it bakes. While your Cheesy Au Gratin Potatoes Recipe is developing these flavors, take a moment to appreciate creating something special for your family!
- Cover the baking dish with foil and bake for 30 minutes. Remove the foil and continue baking for another 20-25 minutes, or until the potatoes are tender and the top is golden brown and bubbly. In my kitchen, this flavorful Cheesy Au Gratin Potatoes Recipe typically takes about an hour to bake fully.
- Let the Cheesy Au Gratin Potatoes Recipe rest for 10-15 minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together. Garnish with fresh parsley for a pop of color and freshness.
This process, tested over numerous family gatherings, ensures a Cheesy Au Gratin Potatoes Recipe that’s both delicious and comforting. Don’t be surprised if your Cheesy Au Gratin Potatoes Recipe develops a slight variation each time you make it – that’s the beauty of homemade cooking!
