Tips and Tricks

I recommend using avocado oil here because we are roasting at high heat, and it is one of the only keto-friendly oils with a high enough smoke point to be safe.
It doesn’t have to be exact, but aim for about 8 cups total of vegetables.
Ensure that you cut the vegetables so that everything is as close as possible to a uniform size.
Make sure that you don’t overcrowd the veggies as this can cause them to steam rather than roast. Use two baking sheets if needed.
I usually use parchment on everything, but this is one recipe where I don’t. First, most parchment paper is safe to a maximum temperature of 420° F. Secondly, direct contact with the making sheet is necessary to get the charr you are looking for.

Frequently Asked Questions

Are roasted vegetables keto?

That depends. Many roasted veggie recipes include vegetables like sweet potatoes, beets, and butternut squash that are not considered keto-friendly. But as long as the vegetables you are using are keto-friendly, then yes, roasted vegetables are keto.

Can you make this recipe ahead?

You can, but for the best texture, I recommend cooking just before serving. If you do want to cook this ahead, consider omitting the eggplant and zucchini as they lose their texture quickly and can get mushy.
