How to Make Thanksgiving Roasted Vegetable Medley Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 425°F (220°C). This high temperature is key to achieving that beautifully caramelized exterior on your vegetables while keeping the insides tender and flavorful.
Step 2: Toss the Vegetables
In a roomy mixing bowl, bring together the halved Brussels sprouts, carrot pieces, diced sweet potatoes, chopped red onion, and cauliflower florets. Make sure each veggie is chopped into pieces of similar size to ensure even cooking.
Step 3: Season Generously
Drizzle the 3 tablespoons of olive oil over your vegetable mix, then sprinkle the dried thyme, dried rosemary, garlic powder, salt, and pepper. Use your hands or a large spoon to toss everything until the veggies are evenly coated—this step guarantees every bite has that herbaceous, savory flavor.
Step 4: Prepare for Roasting
Spread the seasoned vegetables evenly on a large baking sheet, laying them out in a single layer. Avoid overcrowding so the veggies roast instead of steam, which is essential for achieving that perfect crispy edge we all love.
Step 5: Roast to Perfection
Slide the baking sheet into your preheated oven and roast for 25 to 30 minutes. Be sure to stir the vegetables halfway through cooking; this simple step promotes even browning and mouthwatering caramelization on all sides.
Step 6: Rest and Garnish
Once the vegetables turn tender and golden, take them out and let them cool a moment. The flavors will settle beautifully here. Then, transfer the veggies to a serving platter and sprinkle fresh chopped parsley on top for a bright, herbal touch.
How to Serve Thanksgiving Roasted Vegetable Medley Recipe

Garnishes
For an extra burst of freshness and color, sprinkle chopped fresh parsley over the roasted vegetables just before serving. You could also add a squeeze of fresh lemon juice or a sprinkle of toasted nuts to elevate texture and brightness.
Side Dishes
This Thanksgiving Roasted Vegetable Medley Recipe pairs wonderfully with classic mains like roasted turkey, baked ham, or a savory stuffing. It’s also fabulous alongside mashed potatoes or cranberry sauce, creating a balanced plate with varied flavors and textures.
Creative Ways to Present
For a fun twist, serve the roasted vegetable medley in individual mini cast-iron skillets or rustic wooden bowls, and top with a sprinkle of goat cheese or crumbled feta. This adds creaminess and a tangy contrast, making the dish feel extra special for your holiday guests.
Make Ahead and Storage
Storing Leftovers
Got some Thanksgiving Roasted Vegetable Medley Recipe leftovers? No problem! Store them in an airtight container in the refrigerator for up to 4 days. Keeping them cool helps preserve their bright flavors and textures.
Freezing
You can freeze the medley by laying the roasted vegetables on a baking sheet to freeze individually first, then transferring them to a freezer-safe container or bag. They keep well for up to 2 months, making this dish a convenient ready-to-go side anytime you crave those comforting roasted veggie flavors.
Reheating
To enjoy your leftovers at their best, reheat the vegetables in a hot oven around 400°F (205°C) for 10 to 15 minutes. This method helps restore crispiness, rather than microwaving which can make them soggy.
FAQs
Can I use fresh herbs instead of dried?
Absolutely! Fresh thyme and rosemary can be used, but reduce the amount by about half because fresh herbs tend to be more potent. Adding them near the end of roasting preserves their delicate flavor.
What if I want to add more vegetables?
You can definitely mix in other veggies like parsnips, butternut squash, or green beans. Just keep the pieces similar in size and adjust roasting time accordingly to ensure everything cooks evenly.
Is olive oil the best choice for roasting?
Olive oil is great for its flavor and health benefits, but you can also use avocado oil or grapeseed oil, which have higher smoke points for roasting at 425°F if you prefer.
How do I prevent the vegetables from getting mushy?
To keep your medley perfectly roasted and not mushy, cut the vegetables evenly, avoid overcrowding the pan, and roast at a high temperature. Stirring halfway through also helps crisp them up.
Can I make this recipe vegan?
The Thanksgiving Roasted Vegetable Medley Recipe is naturally vegan as written, with just veggies, herbs, and olive oil—making it an easy and inclusive side for everyone at your table.
