Ingredients
- Sweet Potatoes: If you're out of sweet potatoes, try butternut squash for a similar texture and slightly nuttier flavor.
- Brussels Sprouts: Fresh Brussels sprouts take on a delightful crispy texture when roasted. No Brussels sprouts on hand? Try broccoli florets or even chopped zucchini.
- Red Onion: Adding a bit of bite and a pop of color, red onions really make this dish come alive. Yellow onions or shallots can be used as a substitute if needed.
- Avocado Oil: This is my go-to oil for roasting due to its high smoke point. However, olive oil or even coconut oil would work just fine. I don’t like to cook with extra-virgin olive oil at high temperatures.
- Maple Syrup: This adds a touch of natural sweetness that caramelizes beautifully in the oven. Honey or agave syrup can be used as a substitute.
- Sea Salt: If you don't have sea salt, regular table salt or kosher salt will do the trick.
- Crushed Red Pepper Flakes: Feel free to adjust the quantity based on your spice preference or omit it altogether. You could use garlic powder for flavor without the heat.
- Toasted Pecans: These add a delightful crunch and nutty flavor. Feel free to use other nuts. Walnuts or even slivered almonds would be a great alternative. For a nut-free alternative, try a combination of pumpkin seeds and dried cranberries.

Tips and Tricks
- Size Matters: When chopping up your veggies, aim for uniformity. Same-sized pieces mean even cooking, which is key to getting that perfect tender-crisp texture we all love.
- Know Your Oven: Every oven heats a little differently, and very few are true to what the temperature setting reads. I recommend using a reliable oven thermometer in your oven so that you can ensure it is heating to the correct temperature.
- Single Layer Rule: Resist the temptation to overcrowd your baking sheet. Giving each piece its own space allows for better roasting and that dreamy caramelization.
- Sweet Mix-up: For an autumnal twist, try swapping half of the sweet potatoes with diced apples. The mix of savory and sweet is simply divine.
- Pecan Magic: Toasting the pecans before topping the dish enhances their flavor and crunch. Just be sure to keep a close eye on them - they can go from toasty to burnt very quickly.
- Finish Strong: If you would like an extra pop of flavor, drizzle with a little balsamic vinegar or balsamic reduction. You can also add a sprinkle of fresh herbs. Fresh thyme is particularly nice.
- Leftovers Love: If you have leftovers, toss them with some cooked quinoa or farro for a quick and hearty lunch the next day.
Storage Suggestions
Let your roasted vegetables cool down, and then transfer them to a sealed container. You can store them in the fridge for up to four days.
If you've made a big batch and think you won't finish it within that time frame, no worries! These roasted beauties freeze well too.
Just make sure they're in a freezer-safe container or bag, and they can last up to 3 months in the freezer.
Reheating is a breeze. If they're refrigerated, just a couple of minutes in the microwave or a quick sauté on the stovetop will do the trick. If they're coming from the freezer, let them thaw in the fridge overnight before reheating.
