How to make Roasted Autumn Vegetables

Preheat oven to 425 degrees.
Wash and dry the potatoes, carrots, and Brussels sprouts.
Cut the potatoes in half using a sharp knife and place them into a large bowl.
Peel the onion and cut it into quarters. Place into the large bowl.
Peel the butternut squash and remove the seeds. Cut into 1/2 inch squares, then add them to the bowl.
Cut the ends off the Brussels sprouts, then cut them in half and add to the bowl.
Peel and slice carrots into 2-to 3-inch sticks, about 1/4 inch thick. Add to bowl.
Add in the pecan halves.

Combine the olive oil, garlic powder, salt, and pepper in a small bowl, then mix well. Pour over cut vegetables. Toss until everything is well coated.
Spread out evenly in a single layer onto a large sheet pan.

Roast in the oven for 15 minutes.
Remove from the oven and stir the vegetables around, trying to flip most of them over.
Place back in the oven for another 30 – 50 minutes or until the potatoes are fork-tender.

Top with shredded parmesan cheese before serving. (Optional)

Pro Tips for Ultra-Crispy Vegetables

Use high heat: 425°F is the sweet spot for deep caramelization without burning. Drop to 400°F for delicate vegetables or go to 450°F for faster browning on sturdier vegetables.
Do not crowd: Use two sheet pans so steam can escape. Space between pieces matters.
Preheat the pans: Place empty sheets in the oven while it heats. Vegetables sizzle on contact and brown faster.
Dry before oiling: Pat the cut vegetables dry so the oil sticks and the edges remain crisp.
Optional crunch: Toss starchy vegetables with 1/2 to 1 teaspoon cornstarch per pound before roasting. Skip this for beets and squash if you prefer a glossy finish.
Stir once: Flip or stir at the halfway mark to promote even browning.

Finish With Flavor (Choose One or More)

Toss the roasted veggies in a sauce for a flavor boost, or serve one or more sauces on the side.

Maple-Dijon + Thyme: 1 tbsp maple syrup + 1 tbsp Dijon + 1 tsp ACV + pinch salt + chopped fresh thyme. Toss warm veg and serve.
Lemon-Tahini + Parsley: 2 tbsp tahini + juice of 1/2 lemon + warm water to thin + pinch garlic powder + chopped parsley.
Brown-Butter Sage + Pecans: 2 tbsp butter browned with 6 sage leaves. Stir in 2 tbsp chopped toasted pecans and a pinch of salt.

Make-Ahead, Storage, and Reheating

Day-Before Plan: Roast to about 90% doneness. Cool completely. Refrigerate and store flat in a single layer if possible.
Oven Reheat: Preheat the oven to 425°F and place the sheet on a preheated rack for 10–12 minutes. Toss with finishing sauce and serve.
Air Fryer Refresh: Set to 390°F for 4–6 minutes, shaking the basket once during cooking.
Fridge: Up to 4 days. Freezer: Texture softens, but it’s still fine for grain bowls and hashes.

Tips & Tricks

Cater to different tastes by creating a custom vegetable mixture. Omit or add vegetables of your choice. If your family hates carrots, leave them out!
Use the best quality seasonal vegetables for the freshest and cheapest produce. Choose seasonal favorites from a farmers’ market that may not be available in your local grocery store.
Be sure to cut the vegetables into similar sizes to ensure even cooking.
Add a savory flavor with a packet of dry onion soup mix or ranch dressing mix instead of the garlic, salt, and pepper. Or create your own flavor combination using spices you have on hand.
For easy cleanup, line your sheet pan with aluminum foil or parchment paper before adding the vegetables.
For best results, use a large baking sheet so you can arrange the vegetables in an even layer.

Air Fryer and Convection Oven Instructions

Air Fryer

Preheat to 390°F. Work in batches for airflow.
Cook 12–16 minutes depending on cut size, shaking 2–3 times.

Convection Oven

Roast at 400°F. Start checking 20% earlier than standard times.
Rotate sheets if using two racks.
