Ingredients You’ll Need
The ingredients for the Spiralized Winter Veggie Gratin Recipe are simple but thoughtfully chosen. Each vegetable adds its own sweetness and earthiness, while the herbs and cheeses elevate the flavor profile beautifully. When shopping, try to pick firm, fresh winter veggies for the best texture and spiralizing experience.

- Carrots: Choose thick carrots for thicker spirals that hold their shape after baking.
- Butternut squash: Adds creamy texture and subtle nuttiness that’s essential for winter dishes.
- Parsnips: They bring an earthy, slightly sweet depth that balances the other veggies.
- Olive oil: Adds richness and helps coat the veggies evenly with herbs.
- Fresh thyme: Its aromatic notes complement the veggies and cheese beautifully.

- Freshly ground black pepper: Adds just enough heat and complexity.

I love playing around with this Spiralized Winter Veggie Gratin Recipe depending on what herbs or cheeses I have on hand. It’s a flexible dish, so feel free to adjust the seasonings or even swap in other winter veggies that you enjoy – it all turns out delicious.

How to Make Spiralized Winter Veggie Gratin Recipe
Step 1: Prep and Roast the Spiralized Veggies
Preheat your oven to 400°F and lightly spray a 9” x 13” casserole dish with olive oil spray to prevent sticking. In a large bowl, toss together the spiralized sweet potato, carrots, butternut squash, and parsnips. Drizzle with olive oil and add fresh thyme, oregano, parsley, kosher salt, and freshly ground pepper. Toss everything well to coat the veggies evenly.
Spread the mixture into your prepared dish and roast for 40 to 50 minutes, stirring gently halfway through so the veggies cook evenly and develop a bit of caramelization. You’ll know they’re done when they’re fork-tender and fragrant with herbs. This roasting step is key to unlocking the natural sweetness and creating that melt-in-your-mouth texture I love.
Step 2: Make the Creamy Cheese Sauce
While the veggies roast, melt butter in a medium non-stick pan over medium heat. Add chopped shallots and cook them gently for about 4 to 5 minutes until they’re soft and fragrant, which adds lovely sweetness to the sauce. Sprinkle in the flour to form a roux and whisk continually for 1 to 2 minutes to cook off the raw taste.
Slowly add the milk, stirring constantly so the roux fully incorporates and the sauce thickens without lumps. Reduce heat to medium-low and cook the sauce for another 4 minutes until it’s creamy and smooth. Stir in fresh thyme, parmesan, and half of the Gruyere cheese, letting the cheese melt right into the sauce, which gives it that rich, indulgent flavor layer.
Step 3: Combine, Bake, and Serve
Pour the cheesy sauce evenly over the roasted spiralized veggies in the casserole dish. Sprinkle the remaining Gruyere cheese across the top to create a golden, bubbly crust as it bakes. Pop it back in the oven for 10 minutes, just long enough to let the cheese melt and lightly brown.
Once out of the oven, sprinkle the remaining fresh parsley for a pop of color and fresh herb flavor. Serve warm, and get ready for those cozy compliments! This is exactly the kind of dish that makes any meal feel special without making you sweat in the kitchen.
Pro Tips for Making Spiralized Winter Veggie Gratin Recipe
- Choose Similar Size Veggies: Picking veggies of similar size ensures they spiralize evenly and cook uniformly.
- Don’t Overcrowd the Pan: Spread veggies in a single layer while roasting to get even caramelization and tenderness.
- Whisk Constantly for Smooth Sauce: When adding milk to the roux, whisk continuously to avoid lumps and get a silky finish.
- Use Fresh Herbs: Fresh thyme and parsley really lift the flavors—don’t substitute dried here unless you have no choice.
How to Serve Spiralized Winter Veggie Gratin Recipe
Garnishes
I always finish this gratin with a generous sprinkle of fresh Italian parsley—it adds a lovely bright, fresh contrast to the rich cheesy sauce. Sometimes, I’ll also add a light dusting of extra Parmesan right before serving for an extra flavor boost.
Side Dishes
This dish pairs beautifully with roasted chicken or turkey, especially around the holidays. I also like serving it alongside a crisp green salad with vinaigrette—it balances the richness perfectly and makes for a well-rounded meal.
Creative Ways to Present
For special occasions, I sometimes bake the gratin in individual ramekins to create personalized servings that look stunning on a holiday table. Another fun idea is layering spiralized veggies in a glass casserole for a colorful, show-stopping effect before baking.
Make Ahead and Storage
Storing Leftovers
Leftover Spiralized Winter Veggie Gratin keeps wonderfully in an airtight container in the fridge for up to 3 days. I recommend letting it cool completely before storing to maintain the sauce’s creaminess and prevent sogginess.
Freezing
I’ve frozen this gratin successfully by portioning it into freezer-safe containers before baking. When ready to eat, thaw in the fridge overnight, then bake freshly to reheat and bring back that bubbly top and tender texture.
Reheating
The best way I’ve found to reheat the gratin is in the oven at 350°F for about 15-20 minutes, covered loosely with foil to prevent the top from burning while warming through. This keeps it creamy without drying out.
FAQs
-
Can I use frozen spiralized vegetables for this recipe?
While fresh spiralized veggies are ideal for the best texture and roasting results, you can use frozen ones if you drain any excess moisture well and roast for a slightly longer time to avoid sogginess. Just keep an eye on their tenderness as you go.
-
Is this recipe suitable for gluten-free diets?
Yes! Simply swap the all-purpose flour with gluten-free flour when making the sauce roux and ensure your other ingredients (like cheese) are gluten-free certified. The rest of the recipe is naturally gluten-free thanks to the veggies and fresh herbs.
-
What if I don’t have a spiralizer?
No spiralizer? No problem! You can use a vegetable peeler to create thin ribbons or a mandoline slicer to make thin slices of the vegetables. While the texture might change slightly, the gratin will still be delicious and tender.
-
Can I prepare this recipe ahead of time?
Absolutely! You can prep and roast the veggies in advance, make the sauce separately, then assemble and bake the gratin just before serving. This makes it a great dish to prep ahead during busy holiday cooking.
