I’m a firm believer that people who don’t like vegetables just haven’t had the right vegetables prepared the right way yet. And by “right,” I mean right for them. Everyone has different taste buds, and what tastes amazing to one person won’t taste amazing to another.

And to be honest, even though I do like most vegetables, if I have to pick between another serving of vegetables or a bowl of ice cream, nine times out of ten, the ice cream will win.

But this recipe? This is one of the one-in-ten times I will go for the extra vegetables.

I hope you love it as much as I do! (And if not, more for me, right? 😉)

How to Make Keto Oven Roasted Vegetables {Quick Overview}

This is just a quick overview of some of the steps involved in making the low carb roasted vegetables. For the recipe in detail, including exact measurements used at each step, scroll to the recipe card at the end of the post.

Preheat oven and add vegetables to a large bowl.

In small bowl, prepare sauce as noted on the recipe card.

Add sauce to vegetables and toss to coat.

Then add them to a large rimmed baking sheet in a single layer. If your baking sheet isn’t large enough, use two.

Drizzle on balsamic vinegar.

TIP: If you’re not eating keto, you can add more balsamic vinegar to taste. Balsamic vinegar has about 2.7g net carbs per tablespoon, so it can add up quickly if you’re watching your carb intake.

  • These are best served fresh out of the oven.
  • To reheat, it’s preferable that you use the oven instead of the microwave because they will lose their crispness in the microwave.

Can I eat Oven Roasted Vegetables on the Keto Diet?

You can eat oven roasted vegetables on the keto diet as long as you use low carb vegetables and avoid heavy carb vegetables. Eating heavy carb vegetables will knock you out of ketosis by pushing your daily carb intake too high.

Which Oven Roasted Vegetables are Keto-Friendly?

Vegetables that are low carb are keto-friendly. Vegetables that are low carb include broccoli, cauliflower, zucchini, yellow squash, peppers and onions. High carb vegetables like potatoes, corn, and certain squash varieties should be avoided when on a low carb or keto diet.

Do All Vegetables Have the Same Bake Times?

Bake times vary depending on the type of vegetable you are using. Some vegetables bake much faster than others so finding the right mix of vegetables to cook evenly in the oven can be tricky.

Typically, the more dense a vegetable is the more water it has in it. Those particular types of vegetables will take longer to bake in the oven.

Most low carb veggies will bake very well in the oven. However, you will need to be aware of the differing cook times because some vegetables bake faster than others.
