These roasted veggies are healthy, plant based, vegetarian and gluten-free, and even better: beautiful and delicious! We’ve chosen what we think is the best vegetable mix and seasoning blend, and we’re sharing all our roasting tips below.

Why are these the best roasted vegetables?

What makes the best roasted vegetables? Well, lots of things. This recipe uses what we think is the best mix of vegetables and the perfect seasoning blend. Of course, you can use any veggies you like. But we carefully selected each vegetable to be the best mixture we could create! Here’s what we chose and why:

1. Cauliflower, and a little broccoli: Cauliflower roasts up tender and perfectly caramelized. Add a little broccoli for color, but since it can be a little bitter when roasted don’t add too much.
2. Sweet potato: Sweet potatoes bring a tender sweetness to the pan and a bright orange color.
3. Red & yellow peppers: Peppers have a beautifully sweet flavor when roasted, and they don’t take too long to roast.
4. Red onion: Red onion brings sweetness and rounds out the rainbow with a purple color.
5. Seasoning blend: Our best seasoning blend is simple: garlic powder and Old Bay seasoning! It adds the perfect savory blend to the mix.

Even better, the vegetables we chose take only 30 minutes to roast! And you don’t even need to stir. Let’s move on to the method…

How to make roasted vegetables: a tutorial

Roasting vegetables is very easy! While it’s not a fast method, it’s absolutely worth the time investment: and most of it is hands off. Even better, it makes two full sheet pans of vegetables: enough for 8 people as a side. It’s also perfect for making for weekend meal prep and eating throughout the week! Here are the basic steps for this recipe:

Step 1: Chop the vegetables.

This is the most time consuming part of the recipe. If you’re not sure the best way to chop vegetables, we’ve got your back! Our Knife Skills course shows you exactly how to cut 20 fruits and vegetables. Here are the techniques you’ll need for this recipe:

• How to Cut Cauliflower Here’s a method for how to chop florets perfectly: without the mess. The broccoli you can simply chop into florets: no secrets there!
• How to Cut an Onion Fast forward to the method at 1:30, then cut into 1/2-inch slices.
• How to Cut a Bell Pepper Use the method for cutting 1/2-inch strips, then simply cut those in half.
• How to Cut a Sweet Potato All you’ll do is cut it in half lengthwise, then in half lengthwise again, then slice each quarter into pie-shaped slices.

Step 2: Coat with olive oil and seasoning blend.

This recipe makes two large baking sheets of roasted vegetables. Typically we mix our veggies in a bowl with olive oil and seasoning, but because there are so many vegetables for this recipe, you can just place them onto two parchment lined baking sheets and mix with half the olive oil and seasonings. Use your hands to mix them up and make sure everything is evenly coated!

Why use parchment paper when roasting vegetables? It helps with cleanup! No hidden flavor difference here: just cleanup help. We do not recommend using silicone baking mats for roasting vegetables! Baking mats result in veggies that are a little soggier: parchment paper makes the most crispy veggies.

The best seasoning mix? A blend of garlic powder and Old Bay seasoning! It brings in the perfect savory element: you won’t be able to stop eating it. What’s Old Bay and what if you can’t find it? See the section below.

Step 3: Bake at 450 degrees for 30 minutes, rotating the pans after 20 minutes. Do not stir!

Our trick for the best roasted vegetables? Bake at very high heat! We always roast our vegetables at 450 degrees Fahrenheit because it makes them crispy on the outside and tender on the inside. Roasting them at a lower temperature just makes them overall tender: which is nice, just not the best.

Another tip for roasting vegetables is: you don’t necessarily need to stir! This recipe we customized so that you don’t even need to stir: all you need to do is rotate the baking pans after 20 minutes. This way, the bottom of the veggies gets perfectly browned.

And that’s it: how to make the best ever roasted vegetables! Let us know if you try them in the comments below.

What’s Old Bay, and what’s a substitute for it?

Old Bay is an American seasoning blend that’s often used to season seafood: famously in shrimp boils. (Try our Sheet Pan Shrimp Boil, for example!) The main ingredients in Old Bay are paprika, celery salt, black pepper, and crushed red pepper flakes. You can find Old Bay in your grocery store in the spices aisle, or buy Old Bay online.

What’s a substitute for Old Bay? If you can’t find it, for the 2 teaspoons specified in this recipe, use 1 teaspoon paprika and 3/4 teaspoon kosher salt (throw in a few pinches of celery seed if you have it for that classic celery flavor).
