How To Make Roasted Vegetables
Once you know how to roast vegetables, you’ll make them all the time. Let me show you how to roast veggies, and I’ll share my best tips along the way, so that your keto roasted vegetables turn out perfect each and every time.
Preheat the oven. This step is obvious, but worth pointing out because it’s important! The key to the best oven roasted vegetables? A hot, hot oven! Mix up the balsamic oil. Whisk together the olive oil, balsamic vinegar, garlic powder, Italian seasoning, sea salt, and black pepper.
Chop your veggies and toss them with balsamic oil. Drizzle the balsamic oil over the vegetables and toss to coat evenly.
TIP #1: It’s important to cut your vegetables into uniform-sized pieces, so that they cook evenly. TIP #2: If you have any veggies that usually have a longer cook time than others you’re pairing them with, cut those into smaller pieces so that they cook faster. In this case, I picked veggies that all cook at a similar rate, so I cut them into pieces of about the same size.
Arrange vegetables in pan. Place the vegetables in a single layer on the prepared baking sheet.
TIP #3: Do not overcrowd the pan! This is an important step to the best baked vegetables. Make sure each vegetable piece is touching the pan. TIP #4: Use either a foil lined pan, or if you don’t like using foil, just a greased baking sheet. I don’t recommend parchment paper, which tends to get soggy and produces less browned roasted vegetables.
Roast the vegetables. They are done when they have shrunk and turn brown. The browning is what makes them taste so good. Want to see your family devour a pan of veggies? Put these balsamic vegetables in front of them.
Best Vegetables To Roast
Deciding the best vegetables to roast doesn’t have to be complicated! My favorite low carb vegetables to roast include broccoli, cauliflower, zucchini, eggplant, bell peppers, onions, tomatoes, cabbage, asparagus, mushrooms, Brussels sprouts, celery root, and radishes. I have a detailed bulleted list for you below, so you’ll know exactly how long to roast vegetables of all kinds. Also, check my guide on keto vegetables (and the full keto food list) for a full line-up of veggies you can eat on a low carb diet. You can roast most of them!
Which Keto Roasted Vegetables To Make Together?
Choosing the best vegetables to roast is important, but it’s just as important to choose ones that will go well together. Don’t just pick a bunch and hope for the best! The key to roasting mixed vegetables is to choose ones that cook at a similar speed. How do you know that? The primary factors are the hardness of the vegetables and the water content. In particular, root vegetables take longer to roast than others, but most of these are higher in carbs as well. My oven roasted vegetables recipe combines veggies that take about the same amount of time to cook, so they work perfectly together.
How Long To Roast Vegetables In The Oven?
The keto oven roasted vegetables I picked for this recipe – broccoli, cauliflower, zucchini, bell peppers, and red onions – will take about 30 minutes in the oven. Here is a guide for approximately how long to roast vegetables at 400 degrees or 425 degrees (the times are pretty similar):
Asparagus – 12-20 minutes. Notice asparagus takes less time than most veggies, so often is better on its own. Here’s a basic roasted asparagus recipe. Bell peppers – 20-35 minutes. You can roast peppers until they are just crisp tender, or for longer to make them soft and sweet. Bok choy – 15-20 minutes. Try garlic roasted bok choy like this. Broccoli – 25-30 minutes. It’s a must for my balsamic roasted veggies recipe, or you can pair it with cauliflower for parmesan broccoli and cauliflower. Brussels sprouts – 30-45 minutes. The time will vary widely depending on the size of your sprouts. Here’s an easy roasted Brussels sprouts recipe. Butternut squash – 40-45 minutes for cubes. This is a bit higher in carbs so not suitable on its own for keto, but fine for low carb. Here’s a garlic roasted butternut squash recipe. Cabbage – 30-35 minutes. Cabbage takes longer to roast, but it’s worth the wait to get the edges caramelized. My favorite way to make it is cabbage steaks. Cauliflower – 25-30 minutes for florets. You can also make whole roasted cauliflower or garlic roasted cauliflower. Celery root, rutabagas & jicama – 35-45 minutes. These are all great potato replacements for keto French fries. Cherry tomatoes – 15-25 minutes. This will vary a bit depending on their size, but the good news is it’s tough to overcook them. Eggplant – 30-35 minutes. Here’s how to roast eggplant slices. Green beans – 20-25 minutes. Or, try garlic parmesan roasted green beans. Mushrooms – 25-30 minutes. You can throw them in with the recipe below, or make balsamic roasted mushrooms separately. Radishes – 30-40 minutes. Try this crispy roasted radishes recipe! Red or white onion – 25-35 minutes. Most people wouldn’t roast onions on their own, but they pair well with other veggies. I love including them with my balsamic vegetables! Zucchini – 15-30 minutes. Zucchini has a wide range depending on how soft you want it and the size. You can roast it for a longer time like you do in this balsamic roasted vegetables recipe (below), or pair it with quick-roasting veggies, such as in these salmon foil packets.
These are estimates based on veggies cut into large pieces, as shown above. Larger pieces will take longer, and smaller pieces will be less time. TIP: You can combine ones that have a similar cook time, OR cut the ones that have a longer cook time into smaller pieces.
Are Roasted Vegetables Keto?
Yes, oven roasted vegetables are keto diet approved, as long as you use low carb vegetables. Many roasted vegetables recipes feature lots of root vegetables, which are often times a little too high in carbohydrates to be keto. This low carb roasted vegetables recipe utilizes the best vegetables to roast… all keto and low carb options! It has just 8 grams net carbs for generous 1-cup serving. But you don’t have to be keto to enjoy these simple roasted veggies. Everyone will love them!
Can You Make Balsamic Roasted Vegetables Ahead?
Yes, you can make these keto friendly roasted vegetables ahead of time. Keto roasted veggies are just as delicious when they are re-heated, so roast them up and eat them throughout the week. I love them warm, but they are also delicious served up cold or at room temperature. Try them on a cold roast vegetable salad for a veggie-filled meal, or just serve them up with your favorite protein for an easy lunch or dinner.
