Step-by-Step Instructions for https://kitchenbyannak.com/wp-content/uploads/2024/04/Potato-bake-with-sour-cream-cheese-and-garlic-2.jpg?v=1726168889
Step 1: Preheat Oven
Start by preheating your oven to 400°F (200°C). While it’s heating, generously grease a 3-quart baking dish with softened butter to prevent the Cheesy Root Veggie Gratin from sticking. This initial step sets the scene for the creamy goodness that will soon fill your kitchen with delightful aromas.
Step 2: Slice Vegetables
Now, thinly slice your sweet potatoes, parsnips, and beets. For uniform slices, a mandoline works wonders! Keep each vegetable in separate bowls to maintain their unique colors and flavors as you will mix them later. Aim for slices about 1/8 inch thick to ensure even cooking throughout the dish.
Step 3: Mix Cream & Seasoning
In three separate bowls, pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Add freshly grated Parmesan cheese and chopped fresh thyme to each, then season generously with salt and pepper. Toss each bowl to coat the vegetables evenly, infusing them with rich flavors before assembling the gratin.
Step 4: Prepare Baking Dish
At the bottom of your greased baking dish, pour the remaining ¼ cup of cream and sprinkle in minced garlic alongside a bit more Parmesan. Use a spatula to distribute this mixture evenly across the base, laying a flavorful foundation for your Cheesy Root Veggie Gratin.
Step 5: Layering
Begin layering your vegetables by staggering rows of sweet potatoes, parsnips, and beets. Alternate them in beautifully colored layers until your baking dish is filled to the brim with vibrant veggies. This not only enhances the visual appeal but also ensures every forkful is delightfully packed with flavor.
Step 6: Initial Bake
Carefully season the top layer with additional salt and pepper, then finish with the remaining Parmesan. Cover the dish tightly with aluminum foil and bake in the preheated oven for about 30 minutes. This initial bake allows the veggies to begin softening, creating a tender base for your rich gratin.
Step 7: Add Final Cheese Layer
After 30 minutes, remove the foil to reveal your bubbling gratin. Sprinkle Gruyere cheese generously over the top, creating a melty layer that will enhance the dish. Return it to the oven uncovered and bake for another 18-20 minutes, or until the cheese is melted and turns a lovely golden brown.
Step 8: Garnish & Serve
Once out of the oven, let your Cheesy Root Veggie Gratin cool for a few minutes before slicing. To finish, sprinkle with fresh thyme for a touch of brightness and aroma. Serve hot and relish the warm, comforting flavors that make this dish truly special!

Cheesy Root Veggie Gratin Recipe FAQs
How do I select ripe sweet potatoes and parsnips?
Absolutely! When choosing sweet potatoes, look for smooth skins without blemishes or dark spots. They should feel firm and not have any soft spots. For parsnips, you want them to be creamy-white and firm; avoid any that have dark spots or are overly soft as these can indicate they are past their prime.
What is the best way to store leftover Cheesy Root Veggie Gratin?
Very! Store any uneaten gratin in an airtight container in the refrigerator for up to 3 days. If you want to maintain maximum freshness, reheat in the oven, ideally at 350°F (175°C) until hot throughout, which typically takes about 15–20 minutes.
Can I freeze Cheesy Root Veggie Gratin? If so, how?
Absolutely! To freeze, first allow the gratin to cool completely. Then wrap it tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, simply defrost it in the fridge overnight and reheat in a 350°F (175°C) oven for about 20–30 minutes until heated through.
What if my gratin isn’t cooking evenly?
Don’t worry! If you find that your gratin is cooking unevenly or not browning properly, it may be because the vegetable slices are not uniform or packed too tightly together. For the best results, ensure all veggies are thinly sliced with a mandoline for consistency and layered loosely in the dish to allow even cooking and proper heat circulation.
Are there any dietary considerations for allergies in this recipe?
Very! Since this gratin contains dairy, be cautious if you or your guests have lactose intolerance or dairy allergies. For a dairy-free version, consider using coconut cream and plant-based cheeses that melt well, such as cashew cheese or a dairy-free cream alternative.
Can I prepare the gratin ahead of time?
Yes! To prepare in advance, simply layer the veggies in the dish, cover tightly with plastic wrap, and refrigerate for up to 24 hours before baking. When ready, remove the cover and add extra cooking time, about 10–15 additional minutes, as the vegetables will be cold when they go into the oven. This makes it easy to serve a delicious home-cooked meal while saving time on busy weeknights.
