How to Make Cheesy Root Vegetable Gratin
Step 1: Preheat Your Oven
Start by preheating your oven to 400˚F. This ensures that your gratin bakes evenly and reaches that lovely golden-brown top.
Step 2: Prepare the Veggies
Slice those sweet potatoes, parsnips, and beets into very thin rounds. Using a mandoline makes this task quick and easy! Each vegetable should go into its own bowl; this will help keep everything organized as you layer them later.
Step 3: Mix the Creamy Coating
Pour 4 tablespoons of cream over the sweet potatoes and parsnips while adding just 2 tablespoons over the beets. Top each bowl with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme. Don’t forget to season generously with salt and pepper before tossing everything together until well coated!
Step 4: Set Up Your Baking Dish
Pour the remaining ¼ cup cream into the bottom of your greased baking dish. Sprinkle it with another ½ ounce of Parmesan along with the minced garlic. This creamy base adds richness to every layer.
Step 5: Layer Those Veggies
Now comes the fun part! Grab a stack of sweet potato slices and stand them up at an angle at one end of the baking dish. Follow this with rows of parsnips and then beets until you’ve created an eye-catching display—aim for about six rows total.
Step 6: Season & Cover
Sprinkle some salt, pepper, and any leftover Parmesan on top. Cover the dish tightly with foil to lock in moisture while baking.
Step 7: Bake Away!
Place your covered gratin in the oven for about 30 minutes or until those vegetables are soft. This step allows all those flavors to mingle beautifully.
Step 8: Add Gruyere & Uncover
Once soft, uncover your dish and sprinkle shredded gruyere on top. This will melt into gooey perfection!
Step 9: Finish Baking
Put it back in the oven uncovered for another 18 to 20 minutes until it’s fork-tender and bubbly with lightly browned cheese on top.
Step 10: Garnish & Serve
Finish with fresh thyme leaves sprinkled over top—it adds such a lovely touch! Serve warm and watch everyone fall in love with this delightful Cheesy Root Vegetable Gratin!
Pro Tips for Making Cheesy Root Vegetable Gratin
Creating the perfect Cheesy Root Vegetable Gratin is all about technique and a little love. Here are some pro tips to ensure your dish turns out beautifully every time!
- Use a Mandoline for Perfect Slices: Slicing vegetables evenly is crucial for even cooking. A mandoline helps you achieve thin, uniform slices that will cook perfectly in the oven.
- Don’t Skip the Seasoning: Be generous with salt and pepper! These ingredients enhance the natural sweetness of the root vegetables, making each bite more flavorful.
- Layering is Key: When stacking your vegetables, try to alternate colors. This not only adds visual appeal but also allows flavors to blend beautifully as they bake.
- Let it Rest Before Serving: Allowing your gratin to sit for about 10 minutes after baking lets the layers set and makes serving easier. Plus, it gives the flavors a chance to meld together.
- Experiment with Cheese: While we love gruyere, don’t be afraid to mix things up! Try adding different cheeses like mozzarella or cheddar for a unique twist on flavor and texture.
