Choosing the Right Vegetables for Roasted Brussels Sprouts & Butternut Squash
Best Brussels Sprouts for Roasting
Look for bright green Brussels sprouts with tightly packed leaves. Smaller sprouts tend to be sweeter and cook more evenly. Avoid specimens with yellowing leaves, which indicate age, or spots, which suggest decay. Fresh Brussels sprouts should feel firm and heavy for their size.
Selecting Perfect Butternut Squash
Choose butternut squash that feels heavy for its size with a matte (not glossy) skin. The skin should be uniform in color without green lines, which indicate immaturity. The stem should be intact, dry, and firm. A good butternut squash will have a sweet, nutty aroma at the stem end.
Seasonal Substitutions
If Brussels sprouts aren’t available, try using broccoli florets or cabbage wedges. Sweet potatoes make an excellent substitute for butternut squash, offering similar sweetness and a complementary texture when roasted.
Ingredients & Prep for Roasted Brussels Sprouts & Butternut Squash
Vegetable Prep Essentials
Brussels Sprouts: Trim the woody stem ends and remove any discolored outer leaves. For even cooking, cut larger sprouts in half through the stem end, leaving smaller ones whole.
Butternut Squash: Peel completely using a sharp vegetable peeler. Cut in half lengthwise, scoop out seeds, then dice into 1-inch cubes for even cooking.
Seasonings & Oil
- Extra virgin olive oil: 3-4 tablespoons
- Fresh garlic: 3-4 cloves, minced
- Fresh thyme: 2 tablespoons, leaves only
- Fresh rosemary: 1 tablespoon, finely chopped
- Sea salt: 1 teaspoon
- Freshly ground black pepper: ½ teaspoon
- Optional: ¼ teaspoon red pepper flakes for heat
Finishing Touches
- 2 tablespoons maple syrup or honey (drizzled during last 10 minutes)
- ¼ cup toasted pecans or walnuts, roughly chopped
- 2 tablespoons dried cranberries
- Fresh lemon zest from one lemon
Step-by-Step Cooking Instructions for Roasted Brussels Sprouts & Butternut Squash
Pre-Cooking Prep for Roasted Vegetables
- Preheat your oven to 425°F (220°C) with the rack positioned in the middle.
- Line a large rimmed baking sheet with parchment paper or foil for easier cleanup.
- In a large bowl, toss the prepared Brussels sprouts and butternut squash cubes with olive oil, minced garlic, thyme, rosemary, salt, and pepper until evenly coated.
- Spread the vegetables in a single layer on the baking sheet, ensuring they’re not overcrowded. Use two sheets if necessary – crowding leads to steaming instead of roasting.
Roasting Method for Brussels Sprouts & Butternut Squash
- Place the baking sheet in the preheated oven and roast for 20 minutes.
- Remove from oven, stir gently with a spatula to ensure even browning.
- Return to oven and roast for another 10-15 minutes until the vegetables are caramelized on the outside and tender when pierced with a fork.
- If using maple syrup or honey, drizzle it over the vegetables during the last 10 minutes of roasting for beautiful caramelization.
Doneness Check for Roasted Vegetables
Your Brussels sprouts should be golden brown with crispy edges and tender centers. The butternut squash should be caramelized on the outside and easily pierced with a fork. If the butternut squash is done but the Brussels sprouts need more time, remove the squash pieces and continue roasting the sprouts.
Finishing Your Roasted Brussels Sprouts & Butternut Squash
Transfer the roasted vegetables to a serving dish. Immediately toss with toasted nuts, dried cranberries, and fresh lemon zest while still hot. The residual heat will release the aromatic oils in the lemon zest, enhancing the dish’s flavor profile.

Pro Tips for Perfect Roasted Brussels Sprouts & Butternut Squash
Avoiding Common Roasting Mistakes
• Don’t overcrowd the pan – vegetables need space to caramelize properly
• Cut vegetables into similar-sized pieces for even cooking
• Pat vegetables completely dry before roasting to encourage browning
• Use a high enough temperature (425°F is ideal) for proper caramelization
• Season generously – vegetables need more salt than you might think
Tool Recommendations
• Sharp chef’s knife for efficient vegetable prep
• Y-shaped vegetable peeler for easy squash peeling
• Heavy-duty rimmed baking sheet that won’t warp at high temperatures
• Parchment paper for easy cleanup and to prevent sticking
Storage & Reheating of Roasted Vegetables
Store leftovers in an airtight container in the refrigerator for up to 3 days. For best reheating results, spread vegetables on a baking sheet and warm in a 350°F oven for 10 minutes until heated through. Avoid microwave reheating, which will make the vegetables soggy.

FAQs About Roasted Brussels Sprouts & Butternut Squash
Can I prepare this dish ahead of time?
Yes! You can prep all vegetables up to 2 days in advance and store them in airtight containers in the refrigerator. For best results, roast just before serving, but the dish can also be completely prepared up to 4 hours ahead and reheated at 350°F for 10-15 minutes.
Why are my roasted vegetables soggy instead of crispy?
Soggy vegetables usually result from overcrowding the pan, which causes steaming rather than roasting. Make sure your vegetables are arranged in a single layer with space between pieces. Also, ensure your oven is fully preheated to 425°F before roasting.
Can I freeze leftovers?
While possible, freezing will alter the texture of the roasted vegetables. If you must freeze, store in an airtight container for up to 1 month and use in soups or purées rather than as a side dish.
How do I make this recipe vegan?
This recipe is naturally vegan if you use maple syrup instead of honey as a sweetener. All other ingredients are plant-based.
