Step‑by‑Step Instructions for Scalloped Potatoes Au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures the oven is hot enough for perfect baking, leading to that golden, bubbly top we all love. Prepare your 2.5-3 quart casserole dish by greasing it lightly with butter or cooking spray, preventing any sticking during baking.
Step 2: Prepare the Vegetables
While the oven heats, scrub and slice the red potatoes into 1/8-inch rounds—aim for even thickness for consistent cooking. Slice the onion thinly, as well, allowing its sweet flavor to melt into the layers. You’ll have perfectly tender layers once baked, enhancing the overall texture of your Scalloped Potatoes Au Gratin.
Step 3: Layer the Potatoes and Onions
Arrange the potato and onion slices in the greased casserole dish, standing them upright and tightly packed. This method not only creates a visually stunning dish but also ensures even cooking. Each layer will soak in the creamy cheese sauce, making every bite rich and satisfying.
Step 4: Sauté the Garlic
In a medium saucepan over medium-low heat, melt the butter until it’s bubbling gently. Add the minced garlic and sauté for about 1-2 minutes until fragrant, stirring constantly to prevent burning. This step enhances the garlic flavor, infusing the creamy sauce destined for your scalloped potatoes.
Step 5: Create the Roux
Whisk in the all-purpose flour, cooking for 2-3 minutes until it forms a light golden roux. This crucial step helps to eliminate the raw flour taste and creates a thick base for your cheese sauce. The roux should be smooth and free of lumps, providing a perfect foundation for the creamy goodness to come.
Step 6: Add the Half-and-Half
Gradually whisk in the half-and-half, stirring continuously until the mixture thickens and becomes bubbly, about 5-7 minutes. You should see gentle bubbles forming, indicating it’s nearly ready. At this stage, add the dry mustard, salt, and ground black pepper to season your rich sauce perfectly.
Step 7: Incorporate the Cheeses
Once thickened, remove the saucepan from heat and stir in the shredded cheddar and Gruyère cheeses. Continue to mix until the cheeses melt completely, creating a smooth, creamy sauce. Taste the sauce to adjust seasoning if necessary, ensuring each bite of your Scalloped Potatoes Au Gratin will be flavorful.
Step 8: Pour the Sauce Over the Layers
Carefully pour the luscious cheese sauce over the layered potatoes and onions, making sure to cover all the edges. This allows the sauce to seep through the layers, ensuring that every bite is creamy and delicious. Be mindful to evenly distribute the sauce to prevent any dry spots while baking.
Step 9: Bake Covered
Cover the casserole dish tightly with aluminum foil, ensuring it doesn’t touch the cheese sauce. Bake in the preheated oven for 1 hour. This initial covered baking allows the potatoes to steam and cook through, resulting in tender layers smothered in creamy goodness.
Step 10: Bake Uncovered
After one hour, carefully remove the foil and continue to bake uncovered for an additional 20-30 minutes. This will give your scalloped potatoes a beautiful golden-brown top. Look for a bubbly, slightly browned surface and tender potatoes when testing for doneness with a fork.
Step 11: Cool Before Serving
Once baked, remove your Scalloped Potatoes Au Gratin from the oven and allow it to cool for at least 15 minutes before serving. This resting period helps the layers set, making it easier to cut clean servings. The delightful aroma will fill your kitchen, inviting everyone to the table!
