  • Tomatoes – Add a juicy texture and natural sweetness to the dish, enhancing overall flavor. Use cherry or grape tomatoes for a sweeter option. If tomatoes aren’t available, you can substitute with sun-dried tomatoes for a concentrated flavor.
  • Carrots – Contribute sweetness, a satisfying crunch and they caramelize nicely when roasted. If you want to change it up, try using parsnips for a similar sweetness with a slightly different flavor. Sweet potatoes can also work well for a more earthy taste.
  • Yellow Bell Pepper – Provide a sweet, mild flavor and a bright pop of color. If yellow peppers aren’t available, you can use red or orange peppers, which offer similar sweetness. Zucchini can also be a good alternative, though it has a different texture.
  • Asparagus – Adds a unique flavor and tender-crisp texture when roasted. Green beans can serve as a good substitute, providing a similar crunch. Alternatively, you can use snap peas for a sweet and crunchy element.
  • Broccoli – Adds a hearty texture and a slight bitterness that balances the sweetness of other vegetables. Cauliflower can be a great substitute if you want a milder flavor. You can also use Brussels sprouts for a similar crunch and taste.
  • Red Onion – Provides a sharp, slightly sweet flavor and it caramelizes beautifully when roasted. If you prefer a milder taste, you can use yellow or white onions. Shallots also work well for a more delicate flavor.
  • Olive Oil – Helps to roast the vegetables evenly, preventing them from drying out while adding a rich, savory flavor. It also aids in the absorption of fat-soluble vitamins from the vegetables. You can substitute avocado oil for a similar flavor with a higher smoke point. For a different taste, try using sesame oil, but use it sparingly due to its strong flavor.

Serving Suggestions

While these rainbow vegetables are delicious served alongside any main dish, you can turn this into a meal in and of itself with a few quick twists. Make a grain bowl with quinoa, rice, or barley, and add in beans like chickpeas, navy beans, or black beans for protein. If you’re in a rush, toss it with pasta and pack it to go, to enjoy warm, at room temperature, or chilled. If you’re trying to eat more leafy greens, turn it into a delicious salad with a base of arugula or spinach instead. Here are a few more ideas to get you started:

  • Pair with a Protein – Serve your roasted vegetables alongside a plant-based protein like grilled tofu or savory roasted chickpeas. This adds heartiness to your meal and makes it more satisfying.
  • Add a Zesty Dressing – Drizzle a zesty dressing, such as cilantro-tahini or oil-free dill dressing, over the vegetables before serving. This extra flavor can really elevate the dish!
  • Garnish with Fresh Herbs – Top these roasted veggies with fresh herbs like parsley, basil, or cilantro. The herbs add a pop of color and freshness that complements the roasted flavors.
  • Make It a Grain Bowl – Transform your roasted vegetables into a grain bowl by adding quinoa, brown rice, steamed white rice, or farro. This creates a filling and nutritious meal that’s easy to customize.
  • Use as a Tasty Topping – Chop the roasted vegetables and use them as a topping for mini heart pizzas or flatbreads. This adds a burst of flavor and color, making your dish even more appealing.

FAQs

Can I make these rainbow vegetables oil-free?

Yes! You’ll want to use a silicone mat to make sure nothing sticks to the pan. Lightly mist the vegetables with water to make sure the seasonings stick and spritz them again every 10 – 15 minutes while baking.

Can I make these roasted veggies in an air fryer?

You bet, we love air fryer roasted vegetables! Air fryers are pretty small though, so you will have to cook this in two or three batches. Air fry at 370 degrees for 20 – 24 minutes or until crispy (but not burned). You can prepare them in batches and specifically select the cooking time for each vegetable if you’d like to be really precise. 

Can I double this sheet pan recipe for a crowd?

You sure can—the more the merrier! Use two sheet pans to keep everything spread out in one even layer, and rotate the sheets halfway through roasting.

How long will my roasted vegetable leftovers keep?

Stored in an airtight container in the fridge, this dish should keep nicely for up to one week.
