    Keto Roasted Vegetables are satisfying and flavor-packed. They are easy enough for any night of the week and make a great low carb holiday side. I can't help but feel a little virtuous when I serve this colorful dish.

    When it comes to easy sides, I am not sure it gets any better than roasted vegetables.

    These Keto Roasted Vegetables are easy to make and work beautifully for meal prep.

    What Do You Serve with Roasted Keto Vegetables?

    • If there is a more classic combination that a whole roasted chicken and roasted veggies I don't know what it is. This Keto Roasted Chicken makes a great combination.
    • These veggies are fabulous with a steak! Try this Keto Steak Marinade or this Keto Flank Steak and be prepared for compliments all around.
    • This Air Fryer Chicken is easy to make and is always a hit at my house!
    • Instant Pot Rosemary Chicken and Instant Pot Italian Chicken are so full of flavor and super-simple to make.

    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.
    • 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 like to salt the eggplant and let it sit on paper towels for about 30 minutes before proceeding. It isn't necessary, but it will help to prevent bitterness.
    • 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.

    How to Make Keto Roasted Vegetables

    First, start by preheating your oven to 450 degrees. Spray a baking sheet with avocado oil.

    Chop the veggies so that they are about the same size.

    Cutting board with chopped onion, zucchini, brussels sprouts, red pepper, eggplant, cauliflower, and broccoli.

    Place the chopped vegetables in a large bowl and toss with the oil and seasonings.
