this Recipe

Ingredients:

• 1 tablespoon olive oil
• 1 large onion, thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• 1/2 teaspoon dried rosemary
• 1/4 teaspoon ground nutmeg
• 1 pound Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
• 1 pound sweet potatoes, peeled and thinly sliced (about 1/8 inch thick)
• 1 pound parsnips, peeled and thinly sliced (about 1/8 inch thick)
• 1 cup heavy cream
• 1 cup whole milk
• 1/2 teaspoon salt, or to taste
• 1/4 teaspoon black pepper, or to taste
• 8 ounces Gruyere cheese, shredded (about 2 cups)
• 4 ounces Parmesan cheese, finely grated (about 1 cup)
• 2 tablespoons butter, cut into small pieces
• Fresh parsley, chopped, for garnish (optional)

Preparing the Vegetables and Aromatics

Okay, let’s get started! The key to a great gratin is even cooking, and that starts with uniformly sliced vegetables. So, grab your mandoline or a very sharp knife and let’s get slicing!

1. Sauté the Aromatics: In a large skillet, heat the olive oil over medium heat. Add the sliced onion and cook, stirring occasionally, until softened and translucent, about 8-10 minutes. You want them to be nice and sweet, but not browned.
2. Add Garlic and Herbs: Add the minced garlic, dried thyme, and dried rosemary to the skillet. Cook for another minute, stirring constantly, until fragrant. Be careful not to burn the garlic! Burnt garlic is no fun.
3. Season with Nutmeg: Stir in the ground nutmeg. This adds a lovely warmth and depth of flavor to the gratin.
4. Remove from Heat: Take the skillet off the heat and set aside. We’ll be layering this aromatic mixture with the vegetables later.

Layering the Gratin

Now comes the fun part – building our cheesy masterpiece! We’ll be layering the vegetables, cheese, and cream in a way that ensures everything cooks evenly and gets wonderfully cheesy.

1. Preheat Oven: Preheat your oven to 375°F (190°C). This is crucial for even cooking.
2. Grease Baking Dish: Grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the gratin from sticking and make it easier to serve.
3. First Vegetable Layer: Arrange about one-third of the potato slices in a single layer on the bottom of the prepared baking dish. Slightly overlap the slices for even coverage.
4. First Sweet Potato Layer: Arrange about one-third of the sweet potato slices over the potato layer, again slightly overlapping.
5. First Parsnip Layer: Arrange about one-third of the parsnip slices over the sweet potato layer, slightly overlapping.
6. Aromatic Mixture: Spoon about one-third of the sautéed onion and garlic mixture over the vegetables. Distribute it evenly.
7. Cheese Layer: Sprinkle about one-third of the Gruyere cheese and one-third of the Parmesan cheese over the onion mixture.
8. Repeat Layers: Repeat layers of potatoes, sweet potatoes, parsnips, onion mixture, and cheeses two more times, ending with a layer of the remaining Gruyere and Parmesan cheese. Make sure you are distributing the ingredients evenly across the layers.

Adding the Cream and Baking

The cream is what brings everything together, creating that luscious, creamy texture we all crave in a gratin. Don’t skimp on the cream – it’s what makes this dish so decadent!

1. Combine Cream and Milk: In a medium bowl, whisk together the heavy cream and whole milk.
2. Season the Cream: Stir in the salt and pepper. Taste and adjust seasoning as needed. Remember, the cheese is also salty, so don’t overdo it.
3. Pour Cream Mixture: Carefully pour the cream mixture over the layered vegetables and cheese. Make sure the liquid reaches all the layers. You might need to gently press down on the vegetables to help the cream seep through. The cream should almost cover the top layer of vegetables.
4. Dot with Butter: Dot the top of the gratin with the butter pieces. This will help the top get golden brown and crispy.
5. Cover with Foil: Cover the baking dish tightly with aluminum foil. This will help the vegetables cook through without burning the cheese.
6. Bake: Bake in the preheated oven for 45 minutes.
7. Remove Foil: Remove the foil and continue baking for another 30-45 minutes, or until the vegetables are tender and the top is golden brown and bubbly. A knife inserted into the center should meet little resistance. If the top is browning too quickly, you can loosely tent it with foil.
8. Rest: Let the gratin rest for at least 15-20 minutes before serving. This allows the sauce to thicken slightly and makes it easier to slice.

Serving and Garnishing

Finally, the moment we’ve all been waiting for – serving this delicious gratin! A little garnish adds a touch of elegance and freshness.

1. Garnish (Optional): Sprinkle the chopped fresh parsley over the gratin before serving. This adds a pop of color and a fresh, herbaceous flavor.
2. Serve Warm: Serve the gratin warm as a side dish or a vegetarian main course. It pairs perfectly with roasted chicken, pork, or beef.
3. Enjoy!: Dig in and enjoy the creamy, cheesy goodness!

Tips for Success:

• Even Slicing is Key: Uniformly sliced vegetables ensure even cooking. A mandoline is your best friend here, but a sharp knife and a steady hand will also do the trick.
• Don’t Overcrowd the Pan: If your baking dish is too small, the vegetables will steam instead of bake, resulting in a soggy gratin. Use a 9×13 inch dish or divide the mixture between two smaller dishes.
• Adjust Seasoning: Taste the cream mixture before pouring it over the vegetables and adjust the seasoning as needed. Remember that the cheese is salty, so don’t overdo it with the salt.
• Let it Rest: Resist the urge to dig in immediately! Letting the gratin rest for 15-20 minutes allows the sauce to thicken and makes it easier to slice.
• Variations: Feel free to experiment with different root vegetables, such as carrots, celery root, or turnips. You can also add other cheeses, such as Fontina or Gouda.

Make Ahead Instructions:

You can assemble the gratin up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, let it sit at room temperature for 30 minutes before baking as directed. You may need to add 10-15 minutes to the baking time.

Storage Instructions:

Store leftover gratin in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until heated through.

Conclusion:

So, there you have it! This Cheesy Root Vegetable Gratin is more than just a side dish; it’s a celebration of comforting flavors and textures, all baked into one gloriously cheesy masterpiece. I truly believe this recipe is a must-try for anyone looking to elevate their weeknight dinners or impress guests at a special occasion. The combination of sweet and earthy root vegetables, the creamy béchamel sauce, and that perfectly browned, bubbly cheese topping is simply irresistible. It’s a dish that’s both satisfying and surprisingly elegant, making it a winner in my book.

Why is it a must-try? Well, beyond the incredible taste, it’s also incredibly versatile. You can easily adapt it to your own preferences and dietary needs. Not a fan of parsnips? Swap them out for more carrots or sweet potatoes. Want to add a little kick? A pinch of red pepper flakes to the béchamel sauce will do the trick. And the best part? It’s relatively simple to make, even for beginner cooks. The most time-consuming part is prepping the vegetables, but once that’s done, it’s just a matter of layering and baking. Trust me, the effort is well worth the reward.

Serving Suggestions and Variations

This Cheesy Root Vegetable Gratin is fantastic on its own as a vegetarian main course, especially during the colder months. But it also pairs beautifully with a variety of proteins. Think roasted chicken, grilled steak, or even a simple pan-seared salmon. For a complete meal, serve it alongside a fresh green salad with a light vinaigrette.

Looking for variations? Here are a few ideas to get you started:

• Add some greens: Stir in some chopped kale or spinach to the vegetable mixture for added nutrients and flavor.
• Spice it up: Incorporate a pinch of nutmeg or smoked paprika into the béchamel sauce for a warm, comforting flavor.
• Go vegan: Use a plant-based milk and cheese alternative to make a delicious vegan version of this gratin. Nutritional yeast can add a cheesy flavor to the sauce.
• Add some protein: Layer in some cooked lentils or chickpeas for a heartier, more filling dish.
• Experiment with cheese: Try different types of cheese, such as Gruyere, Fontina, or even a sharp cheddar, to create unique flavor profiles.

I personally love serving this gratin with a sprinkle of fresh herbs, like thyme or rosemary, for a touch of freshness. A drizzle of truffle oil (if you’re feeling fancy!) can also elevate the dish to another level. And don’t forget a side of crusty bread for soaking up all that delicious sauce!
