Preheat your oven to 400 degrees Fahrenheit. This initial step is crucial; a hot oven helps in achieving that perfect caramelization on your veggies.
In an extra-large bowl, place the chopped sweet potatoes, cauliflower, bell pepper, zucchini, acorn squash, and Brussels sprouts. Ensure you have a good mix to create a colorful medley.
Pour olive oil over the vegetables. This will not only help with cooking but also enhance the flavors. Remember, a good quality olive oil makes a difference!
Sprinkle the dried basil, dried oregano, black pepper, kosher salt, cinnamon, and garlic powder onto the vegetable mixture. This blend of spices will infuse the veggies with warmth and complexity.
Now, using your hands, toss everything together until all the veggies are well coated in oil and spices. This step is where the magic begins; the oil helps the spices stick and flavors meld.
Prepare a baking sheet by lining it with parchment paper or lightly greasing it. This will prevent sticking and make cleanup a breeze.
Spread the coated vegetables in an even layer on the baking sheet. Make sure they aren't overcrowded; this ensures they roast rather than steam.
Place the baking sheet in the preheated oven. Let the vegetables roast for about 30 to 40 minutes.
Halfway through cooking, take the baking sheet out and flip the veggies. This will help achieve an even roasting, giving that beautiful golden-brown color.
Once the veggies are tender and caramelized, remove them from the oven. The delightful aroma will fill your kitchen, tempting everyone to gather around!
