How to Make Cheesy Root Vegetable Gratin
Step 1: Preheat Your Oven
Preheat your oven to 400ËšF. This step is crucial as it ensures that your gratin cooks evenly and gets that beautifully golden top. While the oven warms up, take a moment to grease your baking dish with softened butter. This will help prevent sticking and add extra flavor.
Step 2: Prepare Your Vegetables
Slice your sweet potatoes, parsnips, and beets into very thin rounds—using a mandoline makes this super easy! Transfer each vegetable into its own bowl so you can mix them with their respective seasonings. This separation helps maintain their distinctive flavors while they cook.
Step 3: Season Each Vegetable
Pour cream over each bowl of sweet potatoes and parsnips, then add cream over the beets. Top each bowl with grated Parmesan and thyme. Don’t forget to season generously with salt and pepper! Toss everything well so every piece is coated; this step enhances their natural flavors during baking.
Step 4: Assemble Your Gratin
Pour remaining cream into the bottom of your greased baking dish along with some Parmesan and minced garlic. Start layering your vegetables by standing them up on their sides—this not only looks stunning but allows each layer to soak up all that delicious creaminess while cooking.
Step 5: Bake It Up!
Once all layers are arranged beautifully in your baking dish, season the top with salt, pepper, and remaining Parmesan before covering it with foil. Bake for about 30 minutes until vegetables soften beautifully.
Step 6: Add Cheesy Goodness
After half an hour, remove the foil and sprinkle shredded gruyere on top. Pop it back in the oven uncovered for another 18 to 20 minutes until everything is fork-tender and has formed a lovely golden crust.
Step 7: Serve & Enjoy!
Once done baking, sprinkle fresh thyme leaves over the top before serving. This final touch adds brightness to your Cheesy Root Vegetable Gratin! Gather around the table with loved ones and enjoy every delicious bite together.
Pro Tips for Making Cheesy Root Vegetable Gratin
