How to Make Vegan Roasted Vegetables

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

Transfer chopped vegetables to a large bowl.
Combine the sauce ingredients and drizzle over the vegetables.
Toss the vegetables to ensure they’re coated.
Transfer vegetables to prepared pans.
Place the pans in the oven and bake for 25 to 30 minutes, until the vegetables are a desired level of tenderness.
Allow them to cool slightly and then serve immediately.

Key Ingredients

Here are the ingredients you’ll need for this recipe, including substitution ideas:

Bell peppers — You’ll need at least two bell peppers. I like to mix up the colors and do one red and one yellow or orange bell peppers. You can use green, but the flavor is a bit stronger.
Zucchini — I prefer using two smaller zucchini instead of one larger one because the smaller zucchinis have better texture.
Yellow squash — Again, I will choose a smaller yellow squash over a larger one for texture purposes.
Carrots — I use about 2 large carrots for this recipe.
Red onion — You’ll need one medium-sized red onion. I love the flavor they add to roasted vegetables.
Cherry tomatoes — If you’re going to add tomatoes to this dish, cherry tomatoes are the way to go. I love everything about them in this dish.
Broccoli florets — You really only need part of a head of broccoli, but they’re so good when roasted in this sauce, that sometimes I’ll add more.
Lemon juice — I highly recommend lemon juice from a freshly squeezed lemon because it’s so much more flavorful.
Dried thyme
Tahini — If you’re not familiar, tahini is basically sesame seed butter. It’s so perfect for this recipe because of its neutral flavor. You can substitute almond butter.
Tamari — I use tamari (or coconut aminos) to keep these roasted veggies gluten-free. If gluten is not on your radar, feel free to substitute soy sauce.

No Oil Roasted Vegetables

You’ll note from the ingredients that this is an oil-free roasted vegetable recipe. Personally, I find this to be my magic sauce and it’s very similar to the one used in this Kale Salad recipe.

If you don’t have tahini and/or you want to add some oil, you can substitute tahini for olive oil. Or you can add a tablespoon of olive oil to the current sauce ingredients.

Freezing Instructions

A common question I hear is, “can you freeze roasted vegetables?”

Thankfully, the answer is yes! In fact, sometimes I’ll make a double batch just so I can enjoy them fresh and freeze some for later. Here’s how to do it:

Prepare roasted vegetables according to the directions.
Allow them to cool.
Transfer in a single layer to a tray lined with waxed paper or parchment paper.
Freeze for 30 minutes.
Once frozen, transfer the veggies to a freezer bag or container.
To reheat, transfer frozen veggies to an oven heated to 300°F/149°C and cook until heated through, around 8 to 10 minutes.

Frequently-Asked Questions

What temperature is best for roasting veggies?

I find the best temperature for roasting veggies is 400°F/205°C. This gets the veggies nice and tender while creating some caramelization, but not too much. Be sure to give veggies room on the pan to allow air to circulate between them.

Is roasted food healthy?

Roasting is a healthy form of cooking because it preserves a lot of nutrients from the veggies.

Notes

Freezer Suggestions

Once the veggies come to room temperature, transfer them to a freezer bag. They can keep frozen for up to 2 months. To reheat, place them in an oven preheated to 350°F/175°C and cook for 5 to 10 minutes.

Starchy Vegetables

You can add chopped potatoes and chopped beets to the mix. First, peel the beets and chop them. They have enough sugar content that they should cook fine in this mix. However, if adding chopped potatoes (peeled or unpeeled), you should steam them for a few minutes first, to help them get tender. Place a saucepan over medium-high heat and bring about 2 inches of water to a boil. Reduce heat to simmer and place a steamer basket in the water. Add the chopped potatoes and cook for up to 10 minutes, until the potatoes are just fork-tender. Then remove them and add them to the mix with the rest of the vegetables.

Sauce Suggestions

Feel free to double the sauce if you have more vegetables or you’d like to drizzle it over freshly roasted veggies before serving.

You can add any of the following to the sauce:

Up to a tablespoon of olive oil
1 tablespoon of brown mustard
Additional herbs, such as basil, rosemary, sage, or parsley.
