## Ingredients You’ll Need

* **Sweet Potatoes:** The star of the show! Choose firm, evenly shaped sweet potatoes for even roasting. Aim for about 2 large sweet potatoes, approximately 1.5 pounds total.
* **Assorted Vegetables:** This is where you can get creative! Some great options include:
* **Brussels Sprouts:** Trimmed and halved (about 1 pound).
* **Carrots:** Peeled and chopped into 1-inch pieces (about 1 pound).
* **Red Onion:** Cut into wedges (1 large).
* **Butternut Squash:** Peeled, seeded, and cubed (about 1 pound).
* **Bell Peppers:** Cored, seeded, and chopped (1-2 peppers, any color).
* **Broccoli Florets:** (About 1 head).
* **Cauliflower Florets:** (About 1 head).
* **Olive Oil:** Extra virgin olive oil is preferred for its flavor and health benefits (about ¼ cup).
* **Maple Syrup:** Use pure maple syrup for the best flavor. Grade A dark amber or Grade B are excellent choices (about 2-3 tablespoons).
* **Fresh Thyme:** Adds a fragrant and earthy note. Fresh thyme is best, but dried can be substituted (about 2 tablespoons fresh, or 1 teaspoon dried).
* **Garlic:** Minced garlic adds a pungent and savory element (2-3 cloves).
* **Salt and Pepper:** To taste. Sea salt and freshly ground black pepper are recommended.
* **Optional:**
* **Balsamic Vinegar:** A drizzle of balsamic vinegar after roasting adds a touch of acidity and complexity.
* **Red Pepper Flakes:** For a hint of heat.
* **Pecans or Walnuts:** Toasted and chopped, for added texture and crunch.

## Step-by-Step Instructions

### 1. Prepare the Vegetables

* **Wash and Dry:** Thoroughly wash all of the vegetables and pat them dry with a clean kitchen towel. This will help them roast properly and prevent them from steaming.
* **Chop the Vegetables:** Cut the vegetables into uniform sizes, about 1-inch pieces. This ensures that they cook evenly. Keep in mind that some vegetables cook faster than others, so adjust the size accordingly. For example, broccoli florets can be slightly larger than carrot pieces. Larger pieces are generally better than smaller; smaller pieces will overcook and burn easier.
* **Peel When Necessary:** Peel the sweet potatoes, carrots, and butternut squash if using. Red onions do not need to be peeled, just remove the outer papery layer.
* **Remove Seeds and Cores:** Remove the seeds and cores from bell peppers and butternut squash. Halve or quarter brussels sprouts.

### 2. Make the Thyme-Maple Glaze

* **Combine Ingredients:** In a small bowl, whisk together the olive oil, maple syrup, minced garlic, fresh thyme (or dried), salt, and pepper. Mix well until the ingredients are emulsified.

### 3. Toss the Vegetables with the Glaze

* **Large Bowl:** Place all of the chopped vegetables into a large bowl. The bowl needs to be large enough to comfortably toss all the vegetables without spilling.
* **Pour and Toss:** Pour the thyme-maple glaze over the vegetables. Use your hands or a large spoon to toss the vegetables until they are evenly coated with the glaze. Make sure every piece gets a little love! Thorough coating helps with caramelization and flavor penetration.

### 4. Roast the Vegetables

* **Preheat Oven:** Preheat your oven to 400°F (200°C). Make sure your oven rack is positioned in the center of the oven for even heat distribution.
* **Prepare Baking Sheet(s):** Line a large baking sheet (or two, if necessary) with parchment paper. Parchment paper makes cleanup easier and prevents the vegetables from sticking to the pan.
* **Arrange Vegetables:** Spread the vegetables in a single layer on the prepared baking sheet(s). Avoid overcrowding the pan, as this will cause the vegetables to steam instead of roast. If necessary, use two baking sheets. Overlapping vegetables will cause uneven cooking and soggy textures.
* **Roast:** Roast for 30-40 minutes, or until the vegetables are tender and slightly caramelized. Flip the vegetables halfway through the roasting time (around 20 minutes) to ensure even browning. The exact roasting time will depend on the size of your vegetable pieces and your oven. Start checking for doneness around 30 minutes and adjust the time accordingly. You’ll know they’re ready when they are easily pierced with a fork and have some nice brown, caramelized edges.

### 5. Finishing Touches (Optional)

* **Balsamic Drizzle:** Once the vegetables are roasted, you can drizzle them with a balsamic glaze for added flavor and tang. A little goes a long way!.
* **Red Pepper Flakes:** If you like a little heat, sprinkle some red pepper flakes over the roasted vegetables.
* **Toasted Nuts:** Sprinkle chopped toasted pecans or walnuts over the vegetables for added crunch and flavor.
* **Fresh Herbs:** Garnish with a sprinkle of fresh thyme or parsley for a pop of color and freshness.

### 6. Serve and Enjoy!

* **Serve Hot:** Serve the roasted sweet potatoes and vegetables immediately while they are hot and tender. They can be served as a side dish, a vegetarian main course, or even as a topping for salads or grain bowls.
* **Storage:** Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.

## Tips for Perfect Roasted Vegetables

* **Don’t Overcrowd the Pan:** As mentioned earlier, overcrowding the pan will cause the vegetables to steam instead of roast. If necessary, use two baking sheets or roast the vegetables in batches.
* **Cut Vegetables into Uniform Sizes:** This is crucial for even cooking. Smaller pieces will cook faster than larger pieces, so try to keep the size consistent.
* **Use High Heat:** Roasting at a high temperature (400°F/200°C) helps the vegetables caramelize and develop a delicious flavor.
* **Don’t Skimp on the Oil:** Olive oil is essential for helping the vegetables roast and prevents them from sticking to the pan. Make sure to coat the vegetables evenly.
* **Season Generously:** Don’t be afraid to season the vegetables generously with salt and pepper. This will enhance their flavor.
* **Flip Halfway Through:** Flipping the vegetables halfway through the roasting time ensures even browning on all sides.
* **Use Fresh Thyme:** Fresh thyme has a much more intense and vibrant flavor than dried thyme. If you can find it, definitely use fresh.
* **Adjust Roasting Time:** The exact roasting time will depend on your oven and the size of your vegetables. Start checking for doneness around 30 minutes and adjust the time accordingly.
* **Let Them Rest:** While you want to serve immediately, let the vegetables rest for a few minutes after they come out of the oven. This allows the juices to redistribute and the flavors to meld together.

## Variations and Substitutions

* **Vegetables:** Feel free to experiment with different vegetables depending on your preferences and what’s in season. Some other great options include parsnips, turnips, fennel, and radishes.
* **Herbs:** If you don’t have thyme, you can substitute other herbs such as rosemary, sage, or oregano.
* **Sweetener:** If you don’t have maple syrup, you can use honey or agave nectar as a substitute.
* **Spice:** Add a pinch of red pepper flakes for a touch of heat, or a dash of smoked paprika for a smoky flavor.
* **Nuts:** Try adding different types of nuts such as walnuts, pecans, or almonds. Toast them before adding them to the vegetables for extra flavor and crunch.
* **Cheese:** Sprinkle crumbled feta cheese or goat cheese over the roasted vegetables for a tangy and creamy finish.
* **Lemon Juice:** A squeeze of lemon juice at the end can brighten up the flavors.
* **Vinegar:** Try different vinegars instead of balsamic. Apple cider vinegar or sherry vinegar work well.

## Frequently Asked Questions (FAQ)

* **Can I use frozen vegetables?** While fresh vegetables are preferred for roasting, you can use frozen vegetables in a pinch. Make sure to thaw them completely and pat them dry before roasting.
* **Can I prepare this dish ahead of time?** You can chop the vegetables and make the thyme-maple glaze ahead of time. Store them separately in the refrigerator until you’re ready to roast. Do not toss the vegetables with the glaze until just before roasting, as this can cause them to become soggy.
* **How do I prevent the vegetables from burning?** Make sure to spread the vegetables in a single layer on the baking sheet and avoid overcrowding the pan. You can also lower the oven temperature slightly if you notice the vegetables are browning too quickly.
* **Can I add protein to this dish?** Yes! Toss in chickpeas, lentils, or tofu before roasting to add protein and make it a complete meal.
* **My sweet potatoes are still hard after 30 minutes, what should I do?** Sweet potatoes can sometimes take longer to cook, especially if they are cut into larger pieces. Continue roasting them, checking every 5-10 minutes, until they are fork-tender. You can also try covering the baking sheet with foil for the last 10 minutes to help them soften up without burning.
