Ingredients You'll Need
The beauty of this recipe lies in its simplicity—just a handful of ingredients that, when combined and roasted to perfection, create something far greater than the sum of their parts. Each component has been carefully selected to contribute specific flavors and textures that harmonize beautifully.
Brussels Sprouts: Choose firm, bright green sprouts with tightly packed leaves. Avoid any with yellowing leaves or black spots. For this recipe, medium-sized sprouts work best—too small and they'll overcook, too large and they won't cook through evenly. If you can find them still on the stalk, that's your freshest option.
Butternut Squash: Look for squash with a matte, tan skin that's free from cuts or soft spots. The heavier it feels for its size, the more moisture and sweetness it contains. Whole squash stores for weeks in a cool, dry place, making this a great pantry staple for impromptu roasting sessions.
Fresh Thyme: This woody herb is essential for the earthy, aromatic notes that define this dish. Fresh thyme has a much more vibrant flavor than dried, with subtle floral and minty undertones. Strip the leaves by running your fingers backward along the stem—it's oddly satisfying!
Garlic: Fresh garlic cloves, smashed and roughly chopped, infuse the vegetables with their pungent aroma. Adding garlic in two stages—first with the squash, then fresh with the sprouts—creates layers of garlicky goodness without any bitter, burnt flavors.
Extra Virgin Olive Oil: Use a good quality oil for roasting. It helps conduct heat evenly, prevents sticking, and carries the flavors of the herbs and seasonings. The slight fruity bitterness of olive oil complements the natural sweetness of the vegetables.
Sea Salt and Black Pepper: Don't be shy with the seasoning! These vegetables can handle more salt than you might think. Use kosher salt for even distribution and freshly cracked black pepper for the best flavor.
How to Make Roasted Brussels Sprouts and Butternut Squash with Garlic and Thyme
Preheat and Prepare
Position your oven rack in the center and preheat to 425°F (220°C). This high temperature is crucial for achieving proper caramelization. Line a large rimmed baking sheet with parchment paper or a silicone baking mat. The rim prevents vegetables from rolling off, while the lining ensures easy cleanup later.
Prep the Butternut Squash
Carefully cut the squash in half lengthwise using a sharp chef's knife. Scoop out the seeds with a spoon (save them for roasting later if you're feeling thrifty!). Peel the squash using a vegetable peeler, then cut into 1-inch cubes. Consistent sizing ensures even cooking—too small and they'll turn to mush, too large and they'll remain crunchy.
Prepare the Brussels Sprouts
Trim the stem ends of the Brussels sprouts, removing any yellowed outer leaves. Cut each sprout into quarters through the stem, creating wedges that will roast beautifully. This cut exposes maximum surface area for browning while keeping the leaves intact. If you have particularly large sprouts, you might need to cut them into sixths.
First Seasoning Stage
In a large bowl, toss the butternut squash cubes with 2 tablespoons olive oil, half the minced garlic, 1 teaspoon salt, ½ teaspoon pepper, and the fresh thyme leaves. The squash needs a head start in the oven, so season it separately. Use your hands to ensure every cube is evenly coated with oil and seasonings.
Initial Roasting
Spread the seasoned squash in a single layer on the prepared baking sheet. Roast for 15 minutes, until just starting to soften and develop golden edges. This head start is crucial because squash takes longer to cook than Brussels sprouts. Don't overcrowd the pan—use two sheets if necessary for proper browning.
Add Brussels Sprouts
While the squash roasts, toss the Brussels sprouts with the remaining tablespoon of olive oil, salt, and pepper. After 15 minutes, remove the baking sheet and add the sprouts to the pan, stirring everything together. Return to the oven and roast for another 15-20 minutes, stirring once halfway through.
Final Garlic Addition
In the last 5 minutes of roasting, add the remaining minced garlic and give everything a good stir. Adding garlic late prevents it from burning and becoming bitter. The heat will mellow its pungency while still maintaining that wonderful aromatic quality.
Check for Doneness
The vegetables are ready when the Brussels sprouts are crispy and browned on the outside, tender inside, and the squash is caramelized and fork-tender. Total cooking time should be 30-35 minutes. If you want extra crispy sprouts, broil for 1-2 minutes at the end, watching carefully to prevent burning.
Rest and Serve
Remove from oven and let rest for 5 minutes. This brief rest allows the vegetables to settle and makes them easier to serve. Taste and adjust seasoning if needed—sometimes a final sprinkle of flaky sea salt makes all the difference. Serve hot or at room temperature.
Expert Tips
Dry Your Vegetables
After washing, thoroughly dry your vegetables with a clean kitchen towel. Excess moisture creates steam, which prevents proper caramelization and leaves you with soggy vegetables instead of crispy, browned perfection.
Don't Crowd the Pan
Give your vegetables room to breathe! Overcrowding leads to steaming rather than roasting. Use two pans if necessary, positioning racks in upper and lower thirds of oven and rotating halfway through cooking.
Preheat Your Pan
Place your empty baking sheet in the oven while it preheats. Starting with a hot pan jump-starts the caramelization process and prevents vegetables from sticking. Just be careful when adding vegetables to the hot pan!
Save Those Leaves
Don't discard the outer leaves that fall off when cutting Brussels sprouts. Toss them with a little oil and spread on the pan—they'll turn into crispy, chip-like treats that are absolutely addictive.
Season Generously
Vegetables need more seasoning than you think. Salt draws out moisture and concentrates flavors. Season in layers—first when tossing with oil, then taste and adjust after roasting for optimal flavor.
Make It Your Own
While thyme is classic, try rosemary, sage, or oregano. Add a splash of balsamic vinegar in the final minutes, or toss with toasted nuts before serving for extra crunch and protein.
Variations to Try
Autumn Harvest Version
Add diced apples and dried cranberries in the last 10 minutes of roasting. The apples provide sweetness and moisture, while cranberries add tart pops of flavor. Finish with toasted pecans for a true autumn celebration.
Mediterranean Twist
Replace thyme with oregano and add kalamata olives, sun-dried tomatoes, and crumbled feta cheese after roasting. A squeeze of fresh lemon juice brightens all the flavors and transports you to the Mediterranean coast.
Spicy Maple Glaze
Whisk together 2 tablespoons maple syrup with 1 teaspoon sriracha and brush over vegetables during the last 5 minutes of roasting. The sweet-spicy combination creates an irresistible glaze that makes these vegetables completely addictive.
Protein-Packed Power Bowl
Serve over quinoa or farro with roasted chickpeas, sliced avocado, and a tahini-lemon dressing. This transforms the side dish into a complete, satisfying vegetarian meal packed with plant-based protein and healthy fats.
Holiday Special
Add roasted chestnuts and fresh pomegranate arils for a festive touch. The chestnuts provide buttery richness while pomegranate seeds offer bright, jewel-like color and tart crunch that makes this dish holiday-table worthy.
Asian-Inspired Version
Use sesame oil instead of olive oil, add ginger and soy sauce, and finish with sesame seeds and scallions. This fusion approach works beautifully and pairs wonderfully with Asian-style main dishes.
Storage Tips
Proper storage is key to maintaining the quality and safety of your roasted vegetables. While they're best enjoyed fresh from the oven, these vegetables store remarkably well and can be repurposed in countless ways throughout the week.
Refrigerator Storage
Store cooled vegetables in an airtight container in the refrigerator for up to 4 days. Line the container with paper towels to absorb excess moisture and prevent sogginess. For best results, store in shallow containers to promote rapid cooling.
Freezing Instructions
While freezing will soften the vegetables, they still work well in soups, stews, and purees. Spread cooled vegetables on a baking sheet to freeze individually, then transfer to freezer bags for up to 3 months. This prevents them from freezing into one solid block.
Reheating Methods
For best results, reheat in a 400°F oven for 8-10 minutes until heated through and crispy. Alternatively, microwave for 1-2 minutes, though this won't restore crispiness. A quick sauté in a hot pan with a touch of oil works wonders for reviving texture.
Make-Ahead Strategy
Prep vegetables up to 3 days ahead and store separately in the refrigerator. The squash can be peeled and cubed, while Brussels sprouts can be trimmed and quartered. Store in zip-top bags with a paper towel to absorb moisture, then roast when ready to serve.
Frequently Asked Questions
Fresh vegetables will always give you the best results for roasting, but in a pinch, you can use frozen. If using frozen Brussels sprouts, thaw completely and pat very dry before roasting. For frozen butternut squash, skip the thawing and add directly to the pan, but expect longer cooking times and less caramelization. Keep in mind that frozen vegetables contain more moisture, so they won't get as crispy as fresh ones.
Soggy vegetables usually result from overcrowding the pan, insufficient oven temperature, or excess moisture. Make sure vegetables are dry before tossing with oil, spread in a single layer with space between pieces, and ensure your oven is fully preheated to 425°F. If needed, use two baking sheets rather than crowding one pan. Also, avoid stirring too frequently—let them develop that golden crust before moving them around.
Great news—this recipe is naturally vegan and gluten-free! All ingredients (vegetables, olive oil, herbs, salt, and pepper) contain no animal products or gluten. If you want to add toppings like cheese or nuts, simply choose plant-based cheese for vegan diets, and ensure any packaged toppings are certified gluten-free if that's a concern for your dietary needs.
Burnt garlic turns bitter and can ruin your entire dish. The key is adding it in stages. Add half the garlic with the squash at the beginning, then add the remaining garlic during the last 5 minutes of roasting. You can also toss garlic with a bit of oil before adding—it helps protect it from direct heat and prevents burning.
These versatile vegetables complement countless main dishes. Try them alongside roasted chicken, grilled steak, baked salmon, or pork tenderloin. They work beautifully with vegetarian proteins like lentil loaf, quinoa-stuffed bell peppers, or marinated tofu. During the holidays, they pair perfectly with turkey, ham, or prime rib. The earthy, sweet flavors complement both rich and light proteins equally well.
Absolutely! This recipe scales beautifully for large gatherings. When doubling, use two baking sheets and rotate their positions halfway through cooking. You may need to increase cooking time by 5-10 minutes since you'll have more vegetables in the oven. For very large crowds, consider making multiple batches rather than overcrowding pans, ensuring each vegetable gets properly caramelized.
