    About Thanksgiving Roasted Vegetables

    With an expansive Thanksgiving meal spread including turkey, sweet potato casserole, squash casseroles, gravy, cranberry sauce, rolls, dressing/stuffing, etc. it might be hard to fit some veggies on your plate.

    Thanksgiving can be quite the feast, and most people skip the veggies in favor of the items that don't always have much to offer in the nutritional department.

    While restriction and diets are terrible & harmful, food can make you feel physically good or bad, energized versus bloated.

    That's why you'll love Thanksgiving Roasted Veggies because they are a delicious way to add veggies to your Thanksgiving or holiday table.

    Don't worry; you don't need to forgo your Thanksgiving favorites and eat salad for Thanksgiving (though this wonderful fall salad would be a tasty choice).

    But what if you added a new soon-to-be favorite dish to your Thanksgiving table? One that makes you want to make room on your plate for veggies!

    That's where this perfect side dish of thanksgiving vegetables come in.

    What are Roasted Veggies for Thanksgiving

    Thanksgiving Vegetables are simply roasted vegetables using veggies that are best in the fall/winter season. Using seasonal veggies gives you the most nutrients while also minding your budget since seasonal veggies are typically less expensive.

    Make a huge batch of roasted vegetables thanksgiving because people will definitely go back for seconds. Even someone who laughs at vegetables on their plate at Thanksgiving ends up loving these.

    Another thing great about this simple recipe, despite its serious nutritious value, is that everyone can enjoy thanksgiving roasted veggies — vegetarians, vegans, carnivores, and those with any of the top eight food allergens (peanuts, tree nuts, soy, eggs, wheat, fish, shellfish, and dairy).

    Plus, you can adapt the veggies you use to the ones that you enjoy and your guests prefer.

    olive oil, red onion, mushroom, yellow onion, Brussels sprouts, sweet potatoes, dried thyme, garlic, salt, and white wine vinegar

    Ingredients

    Veggies: Favorites for this recipe include seasonal vegetables like Brussels sprouts, sweet potatoes, onions, and mushrooms. Sometimes I'll add bell pepper. No need to be super strict with ingredients; simply use whatever is on sale or looks the freshest at the grocery store.

    For onions, red onion, yellow onions, white onion, or sweet onions are all good choices. Mushrooms can be white (button) or baby portobello mushrooms. Potatoes can be any type — regular potatoes, red potatoes, sweet potatoes, or a combo.

    Oil: Olive oil, avocado oil, or canola oil are good options for roasting veggies.

    Herbs: Rosemary and thyme are the two herbs that taste good for Thanksgiving roasted veggies. You can use fresh herbs or dried.

    Salt: Kosher salt, sea salt, or table salt will all work.

    Garlic: Fresh garlic is preferred, but garlic powder can be substituted here. You can also use garlic salt in place of the garlic cloves and salt.

    Vinegar: White wine vinegar is what I typically use, but apple cider vinegar, red wine vinegar, balsamic vinegar, or lemon juice would all work well. The vinegar isn't completely mandatory, but I like how it brightens the flavor of the veggies. Skip it if needed.

    Recipe Tips

    How to Fix a Mistake

    • Not browning: If your veggies are taking a really long time or they're not getting golden brown, they likely are too crowded on the baking sheet. Simple move half of the veggies to another baking sheet, and put them back in the oven. Roast until they are golden brown.
    • Too dry: Add an extra teaspoon or two of oil. After cooking, you can sprinkle the veggies with lemon juice, too.

    Make-Ahead Ideas

    You can roast the veggies in advance for up to three days and store in the fridge in an airtight container. When you're ready to serve, reheat them in the oven until they are warmed through and crispy again. You can also serve them at room temperature.

    Storage Suggestions

    Store the roasted vegetables in an airtight container in the fridge for up to 5 days.

    Freezing is not recommended as the texture will be less than desirable when defrosted. However, if you plan to use the leftover roasted vegetables in soup or on a Roasted Veggie Pizza, freezing them will be fine. Do not freeze for longer than one month.

    If you want to use the leftovers creatively, you can make Leftover Thanksgiving Frittata. You can also toss them into Turkey Quinoa Soup.

    To reheat:

    • In the oven: Place on a baking sheet in a 350°F oven, and heat for about 10-15 minutes until warmed through.
    • In a skillet: In a dry skillet over medium heat, add the veggies and cook for about 5 minutes, stirring often, until warm.

    Variations

    Ingredient Options

    Vegetables: The vegetables can be adjusted depending on your preferences. Vegetables that taste good roasted include onions, mushrooms, carrots, all kinds of potatoes, brussels sprouts, beets, cauliflower, broccoli, parsnips, tomatoes, eggplant, and squash.

    Herbs: Fresh rosemary and fresh thyme both work well. Dried herbs are a good alternative. You can skip the herbs if you want.

    Vinegar: White wine vinegar, red wine vinegar, apple cider vinegar, balsamic vinegar, and lemon juice can all be used. It can also be omitted if needed.

    Alternative Prep and Cooking

    This roasted vegetable recipe can also be made in the air fryer. Follow the direction but cook in an air fryer. Check out this recipe for air fryer bell peppers for tips.

    How to Make Allergy-Friendly

    Luckily, this festive side dish is naturally vegan, gluten-free, dairy-free, nut-free, soy-free, and egg-free. You can adjust the vegetables depending on your taste preferences or if certain veggies work better for your dietary preferences.
