How to Make Cheesy Roasted Root Vegetable Gratin
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C).
While it warms up, grab a 9×13-inch baking dish and grease it with a tablespoon of olive oil.
This step is crucial; it prevents the gratin from sticking and adds a hint of flavor.
The anticipation builds as the oven heats, and you can almost smell the cheesy goodness already!
Step 2: Mix the Vegetables
In a large bowl, combine your sliced potatoes, carrots, parsnips, and onion.
Season them generously with salt, pepper, garlic powder, and thyme.
Toss everything together until the vegetables are evenly coated.
This is where the magic begins!
The colors and aromas will start to mingle, making your kitchen feel like a cozy haven.
Step 3: Layer the Ingredients
Now comes the fun part—layering!
Start by placing half of the vegetable mixture in your greased baking dish.
Sprinkle half of the shredded cheddar cheese over the veggies, letting it melt into the layers.
Next, pour half of the heavy cream over the cheese, ensuring it seeps into the vegetables.
Repeat this process with the remaining veggies, cheese, and cream.
Finally, top it all off with a generous sprinkle of grated Parmesan cheese for that irresistible golden crust.
Step 4: Bake the Gratin
Cover your baking dish with aluminum foil and pop it into the preheated oven.
Bake for 45 minutes, allowing the vegetables to soften and the flavors to meld.
After that, remove the foil and bake for an additional 15-20 minutes.
This step is key for achieving that beautiful golden-brown top that makes your gratin so inviting!
Step 5: Cool and Serve
Once your gratin is out of the oven, let it cool for about 5-10 minutes.
This cooling time allows the layers to set, making it easier to serve.
Scoop out generous portions and enjoy this cheesy delight alongside your favorite protein or salad.
Trust me, your family and friends will be asking for seconds!

Tips for Success
- Use a mandoline slicer for perfectly even vegetable slices, ensuring even cooking.
- Don’t rush the cooling time; it helps the gratin hold its shape when serving.
