Ingredients You’ll Need
Nothing fancy here, just simple, wholesome ingredients that work together to create a symphony of flavors and textures. Each is carefully chosen to contribute either sweetness, creaminess, or a fragrant herbal note that makes this dish unforgettable.
- 2 medium beets, peeled and diced: These give a beautiful color and subtle natural sweetness.
- 3–4 medium parsnips, peeled and sliced into rounds: Add earthiness and a tender bite that complements the beets perfectly.
- 1 large yellow onion, sliced thinly: Creates a soft, caramelized base that enriches the casserole.
- 2 cloves garlic, minced: Adds a burst of savory aroma that’s simply irresistible.
- 2 tbsp olive oil (for roasting): Helps to caramelize the veggies and elevate their natural flavors.
- Salt and pepper, to taste: Essential for balancing and boosting every ingredient’s flavor.
- 1 cup vegetable broth (or chicken broth for extra flavor): Creates depth and moisture in the creamy sauce.
- 1 cup heavy cream or coconut cream (for a dairy-free option): Adds that irresistibly smooth and rich texture to the sauce.
- 1 tbsp fresh thyme (or 1 tsp dried thyme): Brings a gentle herbaceous note to brighten the dish.
- 1 tbsp fresh rosemary, chopped (or 1 tsp dried rosemary): Provides a warm, pine-like aroma that enhances the winter vibe.
- 1 tbsp Dijon mustard (for a bit of tang): Lifts the creamy sauce with subtle sharpness and complexity.
- ½ cup grated Gruyère cheese (or cheddar for a sharper flavor): Melts beautifully and adds a nutty, savory finish.
- ½ cup breadcrumbs (optional, for topping): Gives an irresistible crispy, golden crust on top.
- 1–2 tbsp butter (for greasing the casserole dish): Ensures the casserole doesn’t stick and adds a touch of richness.
How to Make Cozy Winter Vegetable Casserole with Beets & Parsnips Recipe
Step 1: Prep and Roast the Veggies
Start by preheating your oven to 400°F (200°C) and greasing your casserole dish with butter to prevent sticking and add richness. Next, toss the diced beets and sliced parsnips in olive oil, salt, and pepper. Spread them out evenly on a baking sheet, flipping halfway through to ensure they roast evenly. These veggies will soften and caramelize beautifully in about 25 to 30 minutes. The roasting brings out their natural sweetness and develops that deep, comforting flavor you crave during winter.
Step 2: Sauté the Onion and Garlic
While your veggies roast, heat some olive oil or butter in a skillet over medium heat to soften the onion until it’s golden and tender, roughly 8 minutes. Adding the garlic later keeps its flavor fresh and vibrant. This step creates a fragrant and flavorful base that will infuse the cream sauce with irresistible warmth.
Step 3: Craft the Creamy Herb Sauce
Whisk together vegetable broth, heavy cream, Dijon mustard, fresh thyme, rosemary, salt, and pepper in a small bowl. Pour this mixture into the skillet with the softened onions and garlic, letting it simmer to marry all those wonderful flavors. After about 5 minutes, you’ll have a luxuriously creamy sauce that perfectly coats the roasted roots.
Step 4: Assemble the Casserole
Layer your roasted beets and parsnips evenly in the prepared casserole dish. Pour the fragrant cream and onion mixture over the top, being sure to cover every nook and cranny of those tender vegetables. This layering is crucial for allowing the sauce to soak in and create that signature creamy texture of this Cozy Winter Vegetable Casserole with Beets & Parsnips Recipe.
Step 5: Add Cheese and Optional Breadcrumbs
Sprinkle the grated Gruyère cheese or cheddar evenly across the top. If you love a crunchy topping, add breadcrumbs over the cheese—they’ll toast up beautifully while baking, adding both texture and flavor.
Step 6: Bake to Golden Perfection
Cover the dish with foil and bake for 25 minutes first to let everything meld and get heated through without drying out. Then remove the foil and bake an additional 10 to 15 minutes until the top is golden, bubbly, and irresistibly crispy. Letting the casserole rest for 5 minutes before serving will help it set and makes for easy slicing.
How to Serve Cozy Winter Vegetable Casserole with Beets & Parsnips Recipe
Garnishes
Fresh herbs like parsley or extra thyme sprigs on top elevate the dish’s aroma and appearance beautifully. A light sprinkle of Parmesan cheese can add an extra touch of savory richness that pairs well with the Gruyère’s nuttiness.
Side Dishes
This casserole is a wonderful star on its own, especially when paired with a warm crusty bread to soak up every last bit of creamy sauce. It also shines alongside roast chicken, turkey, or lamb, providing a hearty winter vegetable side that rounds out the meal perfectly.
Creative Ways to Present
For a more elegant presentation, serve individual portions in small ramekins or cast iron skillets. You can also layer the casserole in clear glass dishes to showcase the vibrant hues of beets and parsnips, making the dish as eye-catching as it is delicious.
Make Ahead and Storage
Storing Leftovers
This Cozy Winter Vegetable Casserole with Beets & Parsnips Recipe keeps well in an airtight container in the fridge for up to 3 days. The flavors continue to develop, making leftovers just as delightful as the fresh bake.
Freezing
If you want to save some for later, this casserole freezes beautifully. Assemble and bake it, then cool completely before wrapping tightly with foil and plastic wrap. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil for about 20 minutes or until warmed through. For a quicker option, microwave in a covered dish, stirring halfway for even heating. If the topping loses its crispiness, briefly broil for a couple of minutes to refresh that golden crust.
FAQs
Can I make this casserole dairy-free?
Absolutely! Simply substitute the heavy cream with coconut cream and use a dairy-free cheese or omit cheese entirely. Coconut cream adds luscious texture without overpowering the flavors.
What if I don’t have fresh thyme or rosemary?
Dried herbs work perfectly here—just use about one-third of the amount called for fresh, as dried herbs have a more concentrated flavor. Thyme and rosemary are essential for that cozy, fragrant touch.
Can I add other root vegetables?
Yes! Carrots, sweet potatoes, or turnips can be wonderful additions or substitutes. Just adjust roasting times as needed so everything becomes tender without turning mushy.
Is this casserole suitable for meal prepping?
Definitely! It’s a great make-ahead meal since it reheats well and tastes just as comforting the next day. Perfect for busy weekdays or cozy weekend dinners.
How can I make the topping extra crispy?
Be sure to add the breadcrumbs after the cheese, and bake uncovered for the last 10 to 15 minutes. You can also dot some butter on top before baking to enhance browning and crispness.

Sauce
- 1 cup vegetable broth (or chicken broth for extra flavor)
- 1 cup heavy cream or coconut cream (for a dairy-free option)

Topping
- ½ cup grated Gruyère cheese (or cheddar for a sharper flavor)
- ½ cup breadcrumbs (optional, for topping)
- 1–2 tbsp butter (for greasing the casserole dish)
Instructions
- Prepare Oven and Dish: Preheat the oven to 400°F (200°C). Grease a 9×9-inch or similar casserole dish with butter or cooking spray to prevent sticking.
- Roast Beets and Parsnips: In a large bowl, toss the diced beets and parsnips with olive oil, salt, and pepper. Spread them evenly on a baking sheet and roast for 25–30 minutes, flipping halfway through, until tender and caramelized. Use parchment paper if desired to ease cleanup, especially due to beet staining.
- Sauté Onion and Garlic: While the vegetables roast, heat a small amount of olive oil or butter in a skillet over medium heat. Add the thinly sliced onion and cook for about 8 minutes until soft and golden. Add the minced garlic and sauté for an additional minute until fragrant.
- Make Creamy Sauce: In a small bowl, whisk together vegetable broth, heavy cream, Dijon mustard, thyme, rosemary, salt, and pepper. Pour the mixture into the skillet with the onions and garlic, then simmer for about 5 minutes to allow flavors to meld and sauce to thicken slightly.
- Assemble the Casserole: Transfer the roasted beets and parsnips evenly into the prepared casserole dish. Pour the creamy onion sauce over the vegetables, ensuring even coverage.
- Add Cheese and Breadcrumbs: Sprinkle the grated Gruyère cheese evenly over the casserole. If a crunchy topping is desired, add breadcrumbs over the cheese layer as well.
- Bake Covered: Cover the casserole dish with aluminum foil and bake in the preheated oven for 25 minutes to let the flavors combine and ingredients heat through.
- Bake Uncovered: Remove the foil and bake for an additional 10–15 minutes or until the top is golden brown, bubbly, and, if using, the breadcrumbs are toasted and crispy.
- Rest and Serve: Remove the casserole from the oven and allow it to rest for about 5 minutes before serving. This helps the casserole set and makes it easier to slice.
Notes
- For a dairy-free version, substitute heavy cream with coconut cream and use a suitable dairy-free cheese or omit cheese topping.
- Breadcrumb topping is optional but adds a delightful crunch.
- To prevent beet stains on baking sheets, line with parchment paper.
- Works well as a side dish or a vegetarian main course.
- Serve with crusty bread or alongside roast meats for a full meal.
