Blue Cheese Potatoes Au Gratin recipe


  • Author: Sophia

Ingredients

Scale

  • Potatoes:

    • 3 pounds Potatoes: Choose starchy potatoes that hold their shape well during baking and become wonderfully creamy. Russet potatoes are a classic choice and work beautifully. Yukon Gold potatoes are another excellent option, offering a slightly buttery flavor and creamy texture. Avoid waxy potatoes like red potatoes or new potatoes, as they won’t become as tender and creamy in the au gratin.

  • Blue Cheese:

    • 6 ounces Blue Cheese: The star of the show! The type of blue cheese you choose will significantly impact the final flavor profile.

      • Gorgonzola: A milder, creamier Italian blue cheese. It’s a great choice if you’re new to blue cheese or prefer a less intense flavor. It will melt beautifully into the sauce.
      • Roquefort: A stronger, sharper French blue cheese made from sheep’s milk. Roquefort provides a more pronounced blue cheese flavor and a slightly crumbly texture. Use this if you want a bolder taste.
      • Stilton: A rich and complex English blue cheese, often described as having nutty and salty notes. Stilton offers a good balance of flavor and intensity.
      • Danish Blue: A sharper and saltier blue cheese with a pungent aroma. Use Danish Blue sparingly if you are sensitive to strong flavors.

    • For this recipe, a good quality Gorgonzola or a balanced Stilton is highly recommended for a delicious and approachable flavor. You can also use a combination of blue cheeses for added complexity.

  • Dairy Delights:

    • 2 cups Heavy Cream: Heavy cream is essential for creating a rich and decadent cheese sauce. It provides the necessary fat content for a smooth and luxurious texture.
    • 1 cup Whole Milk: Milk thins out the heavy cream slightly, creating the perfect consistency for the sauce while still maintaining richness. Whole milk is preferred for its higher fat content, which contributes to a creamier sauce. You can use 2% milk, but the sauce might be slightly less rich.

  • Aromatics and Flavor Enhancers:

    • 2 cloves Garlic, minced: Fresh garlic adds a subtle savory depth to the sauce that complements the blue cheese beautifully.
    • 4 tablespoons Unsalted Butter: Butter is used to create the roux, the base of the cheese sauce, and adds richness and flavor. Unsalted butter allows you to control the saltiness of the dish.
    • 4 tablespoons All-Purpose Flour: Flour is used to thicken the butter and create the roux, which is essential for a smooth and creamy cheese sauce.
    • 1/4 teaspoon Ground Nutmeg: A pinch of nutmeg adds a warm, subtle spice that enhances the overall flavor profile of the au gratin. It’s a classic pairing with creamy potato dishes.
    • Salt and Freshly Ground Black Pepper: Seasoning is crucial! Salt enhances all the flavors, and freshly ground black pepper adds a touch of spice and complexity. Be mindful of the salt content of your blue cheese, and adjust seasoning accordingly.

  • Optional Enhancements:

    • 1 cup Gruyere Cheese, grated (or other melting cheese): For an extra cheesy topping and a beautiful golden-brown crust, consider adding a layer of grated Gruyere, Fontina, or sharp cheddar cheese on top of the potatoes before baking. Gruyere melts beautifully and adds a nutty, slightly sweet flavor.
    • Fresh Thyme or Parsley, chopped: Fresh herbs add a touch of brightness and visual appeal. Chopped fresh thyme or parsley can be sprinkled over the finished au gratin for a fresh, herbaceous note.


Instructions

Step 1: Potato Preparation

  • Preheat Oven: Preheat your oven to 375°F (190°C).
  • Prepare Potatoes: Wash and peel the potatoes. For the best texture and even cooking, slice the potatoes thinly and evenly. A mandoline slicer is ideal for achieving uniform slices (about 1/8 inch thick), but you can also use a sharp knife. If using a knife, aim for consistent thickness.
  • Soak Potatoes (Optional but Recommended): If you have time, soak the potato slices in cold water for about 30 minutes. This helps remove excess starch, preventing them from becoming gummy and ensuring a creamier texture. Drain and thoroughly pat the potato slices dry with paper towels. Drying the potatoes is important for the sauce to adhere properly.

Step 2: Making the Blue Cheese Sauce

  • Melt Butter: In a medium saucepan over medium heat, melt the butter.
  • Make Roux: Whisk in the flour and cook for 1-2 minutes, stirring constantly, until the roux is smooth and slightly golden. This cooks out the raw flour taste and is crucial for a smooth sauce.
  • Add Milk and Cream: Gradually whisk in the milk and heavy cream, whisking constantly to prevent lumps from forming. Continue whisking until the sauce is smooth and begins to thicken slightly.
  • Add Garlic and Nutmeg: Stir in the minced garlic and ground nutmeg. Season with salt and freshly ground black pepper to taste. Remember that blue cheese is salty, so start with less salt and adjust later.
  • Melt Blue Cheese: Reduce the heat to low and crumble the blue cheese into the sauce. Stir continuously until the blue cheese is melted and the sauce is smooth and creamy. Taste and adjust seasoning as needed. Don’t overheat the sauce once the blue cheese is added, as it can become grainy.

Step 3: Assembling and Baking the Au Gratin

  • Butter Baking Dish: Lightly butter a 9×13 inch baking dish.
  • Layer Potatoes and Sauce: Arrange a layer of potato slices in the bottom of the prepared baking dish, slightly overlapping them. Pour about one-third of the blue cheese sauce evenly over the potatoes. Repeat layers of potatoes and sauce two more times, ending with a layer of sauce. Ensure the sauce covers the potatoes completely to prevent them from drying out during baking.
  • Optional Cheese Topping: If using Gruyere or another cheese topping, sprinkle it evenly over the top layer of sauce.
  • Bake: Bake in the preheated oven for 50-60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly. If the top is browning too quickly, loosely cover the dish with aluminum foil for the last 15-20 minutes of baking.
  • Broil for Browning (Optional): For an even more golden and crisp top, you can broil the au gratin for the last 1-2 minutes of baking, watching carefully to prevent burning.
  • Rest: Remove from the oven and let the Blue Cheese Potatoes Au Gratin rest for 10-15 minutes before serving. This allows the sauce to set slightly and the flavors to meld together.
  • Garnish (Optional): Garnish with chopped fresh thyme or parsley before serving, if desired.
