Preheat your oven to 425°F.
Peel and cut the sweet potato and butternut squash into 1.5-2 inch chunks. Cut the red onion into thick wedges (8 wedges from one onion works well). Peel the garlic cloves but leave them whole. Cut the lemon into wedges if using.
Add all the vegetables (sweet potato, butternut squash, red onion, and garlic) to a large bowl. Drizzle with 2 tablespoon avocado oil and sprinkle with 1 teaspoon salt and ½ teaspoon pepper. Toss until everything is evenly coated.
Spread the vegetables in a single layer on a large rimmed baking sheet. Don't overcrowd the pan—use two sheets if needed. Tuck the lemon wedges and fresh herb sprigs throughout if using.
Roast at 425°F for 45-50 minutes, stirring once halfway through (around the 25-minute mark), until the vegetables are fork-tender and caramelized at the edges.
Squeeze the roasted lemon wedges over the vegetables before serving for extra brightness.
Notes
Cut size matters: Keep vegetable pieces around 1.5-2 inches for even cooking and nice caramelization. Smaller pieces will get crispier; larger pieces stay more tender inside.Don't overcrowd the pan: Use two baking sheets if needed. Crowded vegetables steam instead of roast, which means no golden, caramelized edges.Oil choice: Avocado oil works best for high-heat roasting because of its high smoke point, but olive oil works fine too and adds nice flavor.Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat in a 400°F oven for 8-10 minutes to restore some of the crispy edges.
