Ingredients
- 5 red potatoes, cubed
- 4-5 carrots, peeled and cubed
- 1 red onion, chopped
- 1 ½ cups chopped butternut squash
- 10-15 Brussels sprouts, sliced in half
- ¼ cup olive oil
- 2 lemons, zested and juiced
- 2 tablespoons fresh rosemary, chopped
- 2 garlic cloves, minced
- 1 teaspoon freshly ground black pepper
- 1 teaspoon kosher salt
How to Make Roasted Fall Vegetables
This recipe is incredibly simple, but there are a few tricks that will help you achieve tender vegetables with those beautiful golden-brown edges.
Step 1: Preheat the Oven. Preheat your oven to 425°F. Line a large rimmed baking sheet with nonstick foil or parchment paper.
Step 2: Prepare the Vegetables. Next, wash and prepare all of your vegetables.
Cube the red potatoes and carrots, chop the red onion and butternut squash, and slice the Brussels sprouts in half.
Place all of the chopped vegetables into a large bowl.
Try to cut your vegetables into similarly sized pieces, approximately 1 to 1½ inches, so they cook as evenly as possible.
Step 3: Make the Lemon Rosemary Dressing. In a small bowl, whisk together the olive oil, fresh lemon juice and zest, chopped rosemary, and minced garlic.
Pour the mixture over the vegetables and toss until everything is evenly coated.

Step 4: Arrange on the Sheet Pan. Arrange the vegetables on your prepared baking sheet. This part matters… don’t overcrowd the pan. Try to leave a little space between the vegetables. When vegetables are packed too closely together, they can steam instead of roast.
If necessary, divide the vegetables between two sheet pans.
Sprinkle evenly with kosher salt and freshly ground black pepper.
Step 5: Roast. Finally, roast the vegetables for 20 minutes. Remove the pan from the oven and stir or flip the vegetables. Return to the oven and roast for another 15 to 20 minutes, or until the vegetables are fork-tender and have golden, caramelized edges.
The exact cooking time will depend on how large or small you cut your vegetables.
Serve immediately and enjoy!

The Secret to Perfectly Roasted Vegetables
If you’ve ever roasted vegetables only to end up with a soft or soggy sheet pan, there are a few easy ways to get better results.
Cut Everything to a Similar Size
Aim for pieces approximately 1 to 1½ inches in size. Uniform pieces will cook more evenly.
Don’t Overcrowd the Pan
This is one of the most important tips for roasting vegetables. Spread the vegetables into a single layer with some space between the pieces. If your pan looks crowded, use a second baking sheet.
Use High Heat
Roast the vegetables uncovered at 425°F. The high oven temperature helps create those delicious browned and caramelized edges.
Flip the Vegetables
Stir or flip the vegetables after about 20 minutes so more of their surface comes into contact with the hot baking sheet.
Know When They’re Done
Your roasted vegetables are ready when they’re fork-tender with golden-brown, caramelized edges.
Varying Roasting Veggie Times
How Long Does It Take to Roast Vegetables at 425°F?
Not every vegetable cooks at the same rate, which is important when you’re creating your own sheet pan vegetable combinations.
Longer-Cooking Vegetables: 40-45 Minutes
These heartier vegetables generally need the most time:
- Potatoes
- Sweet potatoes
- Carrots
- Butternut squash
- Beets
- Brussels sprouts
- Onions
Medium-Cooking Vegetables: 25-30 Minutes
These vegetables don’t need quite as long:
- Broccoli
- Cauliflower
- Asparagus
- Green beans
Quick-Cooking Vegetables: 15-20 Minutes
Add these later if you’re combining them with heartier vegetables:
- Bell peppers
- Zucchini
- Mushrooms
- Cherry tomatoes
When combining vegetables with significantly different cooking times, add the quicker-cooking vegetables partway through roasting or cook them separately.
Frequently Asked Questions
Can I Substitute Other Vegetables?
Absolutely. Think of this recipe as a starting point for creating your own roasted vegetable combinations.
Sweet potatoes can be substituted for some of the red potatoes or squash. You can also add broccoli, cauliflower, bell peppers, mushrooms, or other vegetables you already have on hand.
Just remember to account for the different cooking times when mixing heartier root vegetables with quicker-cooking produce.
What Can You Serve with Roasted Fall Vegetables?
These lemon rosemary roasted vegetables pair well with just about any main dish.
Serve them alongside roasted chicken, turkey, pork, steak, or your favorite plant-based protein.

Are Roasted Fall Vegetables Good for Meal Prep?
Yes! This recipe is an easy way to prepare several vegetables at once.
Divide the roasted vegetables into meal-prep containers with rice or another grain and your favorite protein for easy lunches throughout the week.
You can also add leftover roasted vegetables to salads, grain bowls, wraps, or breakfast dishes.
How to Store Leftover Roasted Vegetables
Allow leftover vegetables to cool before transferring them to an airtight container.
Store them in the refrigerator for 3 to 4 days.
Reheat them in the oven or microwave, or enjoy them cold as part of a salad or grain bowl.
Freezing isn’t recommended because the vegetables can become mushy after they’re frozen and reheated.
