I love making these colorful roasted vegetables because they’re simple, flavorful, and a favorite side dish for building quick, well-balanced meals. I pair these easy roasted vegetables with chicken, pork tenderloin, salmon, steak, and even scrambled eggs.

Recipe Highlights
Easy vegetables. Roasting brings out the natural sweetness and flavor of vegetables while creating deliciously caramelized edges and tender centers.
Just one sheet pan. I love the simplicity of tossing everything onto one large baking sheet, seasoning quickly, and letting the oven do the work.
Easy to customize. This recipe is incredibly flexible and works with almost any sturdy vegetables that are good for roasting, making it a great clean-out-the-fridge side dish option. It’s also a nice side dish option when serving someone with food intolerances, since they naturally gluten free, dairy free, and vegetarian.
Perfect for meal prep. A batch of roasted vegetables makes it easy to add a flavorful serving of vegetables to lunches and dinners throughout the week. They’re perfect for adding to grain bowls, salads, and pasta dishes as an easy way to work in more vegetables.

Ingredient Notes And Substitutions
Here’s what I gather to make these sheet pan roasted veggies:
- Sweet potato: Sweet potatoes add natural sweetness, color, and a soft, creamy texture when roasted. I recommend cutting them into ½- to ¾-inch cubes so they cook at a similar rate as the other vegetables.
- Cauliflower: Cauliflower develops delicious browned edges when roasted and adds a hearty texture. Bite-size florets work best.
- Green beans: Green beans add fresh flavor and a little crunch. I trim the ends before adding them to the pan.
- Brussels sprouts: Halving the Brussels sprouts helps them cook through. It creates plenty of surface area for those golden, caramelized edges.
- Red onion: Red onion becomes sweeter and more tender as it roasts, adding a delicious contrast to the other vegetables.
- Garlic: Fresh minced garlic adds savory flavor throughout the vegetables, and I love that the garlic gets lightly roasted along with everything else. Garlic powder also works in a pinch.
- Avocado oil: A little avocado oil helps the vegetables brown and crisp in the oven while helping the seasonings adhere to the vegetables. Extra virgin olive oil also works just fine.
- Salt and pepper: A sprinkle of fine kosher salt and sea salt and ground black pepper are all that’s really needed to make the natural sweet and savory flavors of the veggies pop.
- Dried herbs: Dried herbs are optional, but Italian seasoning, thyme, rosemary, or oregano can add another layer of flavor. If I have them on hand, I might sprinkle fresh herbs over the veggies after roasting. A little Parmesan cheese, paprika, fresh squeezed lemon juice, or red pepper flakes also are great seasoning options.
- Other vegetables: Regular potatoes, red potatoes, broccoli florets, carrots, zucchini, yellow squash, asparagus, winter squash, butternut squash, turnips, and parsnips are all excellent choices for roasting. I love mixing and matching vegetables based on what is available in the refrigerator. Keep in mind that vegetables roast at different rates depending on their density and moisture content, so cutting everything into appropriately sized pieces helps it cook more evenly. If using softer veggies, like mushrooms, bell peppers, cherry tomatoes, beets, or chopped eggplant, add them to the sheet pan later since they have a faster roasting time and are more delicate.

Prepare And Roast The Vegetables
Here are some of my tricks and tips after making these roasted vegetables in my own home kitchen so many times:
- Cut the veggies evenly: The key to great roasted vegetables starts with cutting the vegetables into pieces that are relatively similar in size. Denser vegetables, such as sweet potatoes and Brussels sprouts, need enough time to become tender, while smaller or more delicate vegetables can cook more quickly.
- Season the veggies: Next, I toss all of the vegetables with avocado oil directly on a large sheet pan. This means I don’t need to dirty an extra bowl and I can make sure every piece gets lightly coated with oil. I don’t use parchment paper so the veggies come in contact with the high heat of the pan. Then I spread everything into a single, even layer before seasoning with salt and pepper. The vegetables should have enough space around them to allow the hot air to circulate.
- Roast the veggies: These vegetables roast at 375°F. I like to stir and toss them about halfway through cooking with a flat spatula. To know they’re done, I look for vegetables that are fork-tender with some browned, caramelized edges. The exact cooking time can vary depending on the size of the pieces and the vegetables used. So looking for visual cues is more helpful than relying on the clock alone.

Don’t Overcrowd The Pan
One of the biggest secrets to perfectly roasted vegetables is giving them enough room so hot air can circulate around the individual pieces and create those ideal caramelized edges. I recommend using a large 18 x 13-inch sheet pan for about 7 cups of raw vegetables.
When the vegetables are packed too tightly together, moisture gets trapped between the pieces. Instead of roasting and developing those delicious golden, caramelized sides, the vegetables essentially steam.
If everything doesn’t fit comfortably in a single layer, I recommend using two sheet pans rather than crowding one. A little extra space makes a big difference in texture and browning.

Favorite Ways To Serve Them
I love serving these roasted vegetables alongside this pork tenderloin recipe, which is especially convenient since they roast at the exact same temperature. These veggies are also a nice complement to roasted chicken, salmon, steak, pork chops, or burgers for a simple, balanced meal. Adding a protein to a container of these roasted vegetables makes an especially easy meal prep lunch or dinner.
I’ve also used these leftover roasted veggies in grain bowls along with rice, lentils, or quinoa. Or tossed them into salads, added them to wraps, mixed them into pasta dishes, or simply drizzled balsamic glaze over top. Having a container of these roasted vegetables ready in the refrigerator makes it so much easier to add a flavorful serving of vegetables to almost any meal.

Storing And Reheating Leftovers
I store leftover roasted vegetables in an airtight container in the refrigerator for up to 3 days. They make a great meal prep component because they can be portioned out throughout the week for lunches and dinners.
For the best texture, I recommend reheating roasted vegetables in the oven, toaster oven, or air fryer rather than in the microwave. The dry, circulating heat helps bring back some of those crispy, caramelized edges.
Frequently Asked Questions
They can work in a pinch. But for the best texture and flavor, I much prefer roasting raw hard veggies instead of pre-frozen ones. Frozen vegetables contain more moisture, so overcrowding the pan can make them steam rather than roast. If using them, thaw and drain them first, then pat dry to remove as much moisture as possible.
The biggest factors are avoiding overcrowding, using enough oven heat, and giving the vegetables plenty of space on the pan. I also recommend spreading the vegetables into a single layer and flipping them halfway through cooking. If the pan looks crowded, divide the vegetables between two sheet pans so moisture can escape and the edges have room to caramelize.
