Preparing Root Vegetable Gratin
Creating a delightful root vegetable gratin can be a rewarding experience, especially as the comforting aroma fills your kitchen. Let’s walk through this step-by-step process so you can impress family and friends with this hearty dish.
Clean and peel the vegetables
First things first—cleanliness is key in the kitchen! Start by thoroughly washing your root vegetables to remove any dirt. After cleaning, peel them with a vegetable peeler. A good tip to remember: always peel the red beets last, as they tend to stain everything in their path. Trust me, you don’t want to walk around with crimson hands while preparing your meal!
Slice the vegetables properly
Once your vegetables are all prepped, it’s time to slice them. Use a mandoline slicer for precision and uniformity, which is fabulous for even cooking. If you’re more comfortable with a knife, take your time to make thin, even rounds, which ensures that every piece cooks uniformly. This might take a little patience, but it’s totally worth it in the end! Keep each type of vegetable separate in bowls to make the next steps smooth and organized.
Mix the vegetables with cream and seasoning
Now, let’s flavor things up! Pour about ¼ cup of heavy cream over each type of sliced vegetable. Then, add a sprinkle of dried thyme and a generous pinch of salt and pepper—these seasonings will elevate your dish. Don’t forget to toss in about half an ounce of Parmesan cheese into each bowl and mix thoroughly until everything is well-coated. This step is crucial because it allows each vegetable to absorb those rich flavors.
Preheat the oven and prepare the baking dish
While you’re mixing, go ahead and preheat your oven to 400°F (200°C). Grease an oval roasting pan with a touch of oil or butter. This ensures that your root vegetable gratin won’t stick and makes for easy serving later on.
Layer the vegetables and pour the remaining cream
It’s time for the fun part—layering! Start by pouring the remaining ¼ cup of heavy whipping cream into the bottom of your prepared pan. Add in the minced garlic for a burst of flavor. Then, begin arranging your stacked vegetables: sweet potatoes, beets, and parsnips, ensuring each layer looks visually appealing. Finally, pour any leftover cream mixture over the top and add a touch more salt and pepper for good measure.
Bake and add the cheese
Cover your pan with foil and pop it into the preheated oven. Bake for about 30 minutes, or until the vegetables are softened. After the first half of baking, remove the foil and sprinkle the top with shredded Gruyere and any remaining Parmesan cheese. Return it to the oven for an additional 20 minutes, until the cheese is beautifully golden and bubbling.
And there you have it—an effortless yet impressive root vegetable gratin that’s perfect for family dinners or cozy gatherings. Enjoy the warmth and comfort of this delicious dish; your taste buds will thank you!
