    OVEN ROASTED VEGETABLES TITLE IMAGE

    Like roasted potatoes, vegetables roasted in the oven are very easy and delicious. 

    It isn’t a recipe that takes much planning but creates a comfort food meal with deep flavors. 

    Change up the recipe with what you have on hand! Suggested swaps are included below.

    Easy Oven Roasted Vegetables

    Roasted vegetables is one of the easiest side dish recipes for any meal. You can pick your favorite vegetables (with two guidelines). 

    Roasting the vegetables over higher heat helps caramelize their natural sugars to give them a delicious flavor and texture. 

    Adding the rosemary maple mustard drizzle in this roasted vegetable recipe is perfection.

    The simple oil and seasoning makes these roasted veggies a favorite.

    Recipe Ingredients + Notes

    The Vegetables

    We selected a variety of cool weather vegetables that are colorful and delicious when roasted.

    Brussels sprouts. These look like tiny cabbages and are delicious when roasted. They are often sold on the stalk. Just cut the individual sprouts from the stalk and proceed with the recipel

    Butternut Squash. Probably the favorite and most easy to find of the winter squashes. It’s delicious in butternut squash noodles and butternut squash soup.

    It’s a great addition to any roasted vegetable combo.

    Timesaving Tip: grocery stores often sell fresh peeled, cubed butternut squash. This will save you the time preparing it. 

    Sweet Potato. Packed with flavor and nutrition, sweet potatoes add great flavor. As they cook the caramelize crust adds a savory compliment to their naturally sweet flavor. 

    Any color sweet potato can be used. Yams can be substituted too.

    Carrots. Use larger carrots cut into 1-inch long pieces. Any color carrots can be used too!

    Onion. Choose a large onion and cut it into 1/8’s wedges. As the vegetables cook the onion will separate and evenly spread amongst the other vegetables. 

    Any color onion can be used. Red onions are a bit sweeter when roasted.

    Garlic. Whole peeled garlic cloves are added to the vegetables.

    The Maple Mustard Sauce

    This delicious sweet and savory sauce makes these vegetables a superstar dish. It’s simple and easy to prepare.

    Olive Oil. Coats the vegetables perfectly for roasting adding some delicious flavor.

    Maple Syrup. This adds a sweet note to the sauce. 

    Whole Grain Mustard. Also called Country Mustard, this style of mustard is rustic with whole mustard seeds in it. It has a great homey texture and delicious Dijon-type flavor. It’s less tangy than yellow mustard.

    Salt. I recommend using Kosher salt. It’s a less salty flavored salt and distributes well when sprinkled over food.

    Fresh Rosemary. Strong, aromatic rosemary punches up the flavor of the roasted vegetables. It’s added in sprigs so easy to remove when eating.

    How to Substitute Different Vegetables

    There are two tricks to making perfect roasted vegetables: 

    1. Choose vegetables that have a similar density 
    2. Cut the vegetables into similar sizes 

    This ensures all the vegetables will cook in the same amount of time.

    This recipe uses winter vegetables and root vegetables which are more dense with lower moisture. 

    If you wanted to swap in something here are some other suggestions:

    Beets

    Turnips

    Regular potatoes or yams

    Rutabaga

    Radishes

    Other winter squash; acorn, pumpkin, delicata. NOTE: delicata and acorn squash do not need to be peeled. The skin is edible.

    How to Swap in Shorter Cooking Vegetables

    The smaller the vegetables are cut the faster they will cook. If mixing longer cooking and shorter cooking vegetables, cut the long cook type into a smaller size.

    How to Make it – Step-by-Step

    Preheat oven to 425 degrees.

    Arrange vegetables in a single layer on a sheet pan. Add rosemary sprigs on top. NOTE: the sheet pan can be lined with parchment paper if desired.

    Drizzle evenly with the sauce.

    Roast for cook time of 40-45 minutes. Flip the vegetables once or twice during cooking. Cook until the vegetables are cooked through (not mushy) and slightly charred.

    Pro Tips

    Keep vegetables in a single layer for even cooking.

    Turn the vegetables one to two times during cooking for even cooking.

    What to serve with Roasted Vegetables

      Roasting veggies is one of my very favorite techniques for coaxing big flavors out of humble ingredients. Even more amazing drizzled with this yummy sauce! And thanks for the great tips, like about subbing different veggies in a way that they’ll still roast properly and even saving time by purchasing butternut squash already prepped at the grocery store!
