This festive collection brings together three dependable Christmas sides: rosemary-garlic roast potatoes, maple-glazed carrots, and crisp Brussels sprouts with cranberries and pecans. They share an oven-friendly approach, use familiar ingredients, and add a mix of savory, sweet, and tart flavors to the holiday table.
Ingredients
- For the rosemary-garlic roast potatoes: 2 pounds Yukon Gold potatoes, peeled if desired and cut into 1½-inch pieces
- 3 tablespoons olive oil
- 1 teaspoon kosher salt, plus more for the cooking water
- ½ teaspoon black pepper
- 2 garlic cloves, finely grated or minced
- 1 tablespoon chopped fresh rosemary
- For the maple-glazed carrots: 1½ pounds carrots, peeled and cut into evenly sized batons
- 1 tablespoon olive oil
- 2 tablespoons unsalted butter, melted
- 1½ tablespoons pure maple syrup
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- 1 teaspoon chopped fresh thyme leaves
- For the Brussels sprouts: 1½ pounds Brussels sprouts, trimmed and halved lengthwise
- 1½ tablespoons olive oil
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ⅓ cup dried cranberries
- ⅓ cup pecans, roughly chopped
- 1 tablespoon balsamic vinegar
Instructions
- Heat the oven and prepare pans. Set a rack in the upper-middle position and heat the oven to 425°F (220°C). Line two large rimmed baking sheets with parchment for easier cleanup. Give the vegetables room to brown; use a third pan if needed rather than crowding them.
- Parboil the potatoes. Put the potato pieces in a large saucepan, cover with cold water by about an inch, and add a generous pinch of salt. Bring to a boil, then simmer for 8–10 minutes, until the outsides are tender but the centers are still firm. Drain well and leave in the colander for 2 minutes so steam can escape.
- Season the potatoes. Return the drained potatoes to the warm, dry pan and shake gently to roughen their edges. Toss with the olive oil, salt, and pepper. Spread them on one baking sheet in a single layer, cut sides down where possible. Roast for 20 minutes before turning.
- Prepare the carrots and sprouts while the potatoes roast. Toss the carrots with the olive oil, melted butter, maple syrup, salt, pepper, and thyme. Arrange them in one layer on the second pan. In a bowl, toss the Brussels sprouts with their olive oil, salt, and pepper; keep them on the same pan if there is room, or use another sheet. Place sprouts cut sides down for better browning.
- Roast the vegetables. After the potatoes have roasted for 20 minutes, turn them. Put the carrot and Brussels sprout pans in the oven. Roast everything for another 20–25 minutes, checking the carrots and sprouts after 18 minutes. The potatoes should be deeply golden and crisp, carrots tender when pierced, and sprouts browned at the edges. Rotate pans between racks if one side cooks faster.
- Finish each side. Stir the garlic and rosemary into the hot potatoes as soon as they come out of the oven; adding garlic near the end helps prevent it from burning. Toss the roasted carrots in their pan juices. Stir the cranberries and pecans into the sprouts during their final 5 minutes of roasting, then drizzle with balsamic vinegar and toss. Taste and adjust seasoning before serving.
Tips
- Cut vegetables into similar-sized pieces so they finish at about the same time. Smaller carrots may cook faster; remove them when tender rather than waiting for larger pieces.
- For crisp potatoes, drain them thoroughly and let steam escape before adding oil. A crowded pan traps moisture and encourages steaming instead of browning.
- If you only have one oven rack or limited pan space, roast the potatoes first and keep them loosely covered in a warm oven. Roast the other vegetables afterward; refresh potatoes at 425°F for 5–8 minutes before serving.
- For nut allergies, omit the pecans or replace them with toasted pumpkin seeds. Keep the seeds separate until serving so they stay crisp.
Serving Suggestions
Serve these sides warm alongside roast turkey, glazed ham, roast chicken, or a vegetarian main such as lentil loaf. Their different textures and flavors balance rich gravies and sauces: potatoes are savory and crisp, carrots are gently sweet, and sprouts bring tart fruit and a little crunch. Put each dish in its own serving bowl so guests can choose portions, and bring extra salt, pepper, and balsamic vinegar to the table.
Variations
Swap rosemary for chopped parsley or sage in the potatoes, or finish them with a tablespoon of grated Parmesan. For a citrus note, add a teaspoon of orange zest to the carrots after roasting; honey can replace maple syrup in the same quantity. The Brussels sprouts are also good with pomegranate seeds instead of cranberries, added after roasting, or with toasted hazelnuts instead of pecans. If using salted butter, reduce the added salt in the carrots slightly and taste before serving.
Storage and Reheating
Cool cooked vegetables promptly and refrigerate them in separate airtight containers within 2 hours of cooking. They keep for 3–4 days in a refrigerator at 40°F (4°C) or colder. Reheat potatoes on a baking sheet at 400°F for 8–12 minutes to restore some crispness. Warm carrots and Brussels sprouts in a covered oven-safe dish at 350°F for about 10–15 minutes, or microwave in short intervals until steaming hot throughout. Add a splash of water to carrots if their glaze has thickened. Avoid reheating the full batch more than once, and discard food left at room temperature longer than 2 hours (1 hour if the temperature is above 90°F).
Frequently Asked Questions
Can I prepare these Christmas sides ahead?
You can peel and cut the potatoes and carrots up to a day ahead; store them separately in cold water in the refrigerator, then drain and dry very well before cooking. Trim and halve Brussels sprouts a day ahead and refrigerate them in a covered container. For the best texture, roast the vegetables close to serving time.
Can I cook all three sides at the same time?
Yes, if your oven has enough space for the pans without blocking airflow. The vegetables roast at the same temperature, but they may finish at different times, so check each pan separately. Rotate the sheets and swap rack positions once if your oven heats unevenly.
How do I know when the vegetables are done?
Potatoes should have crisp, browned edges and a tender center; test with a small knife. Carrots should be easily pierced but not falling apart. Brussels sprouts should be browned on their cut faces and tender when pierced. Add a few minutes of roasting if needed.
Can I use baby carrots or frozen Brussels sprouts?
Baby carrots can be used whole if they are small, or halved lengthwise if thick; check them early because their size varies. Fresh sprouts give the best roasted texture. Frozen sprouts tend to release more moisture, so thaw them fully, pat them very dry, and expect less crisp browning.
How can I keep the sides warm before dinner?
Hold finished vegetables in separate oven-safe dishes in a 200°F oven for up to about 30 minutes. Keep potatoes uncovered so they do not soften, and cover the carrots and sprouts loosely to reduce drying. For food safety, keep hot food at 140°F or above; refrigerate leftovers promptly after the meal.
