Now is the perfect time for this dish. Nothing captures the essence of autumn like roasted vegetables. This recipe combines Brussels sprouts, butternut squash, and cranberries for a side that is both simple and impressive. It requires minimal hands-on work and delivers maximum flavor.
Why This Recipe Works
- High-heat roasting caramelizes the vegetables, creating deep, sweet flavors.
- The cranberries add a necessary pop of tartness that balances the dish.
- Using a single sheet pan makes preparation and cleanup straightforward.
- Simple seasoning with olive oil, salt, and pepper lets the natural flavors shine.
Ingredients
- 1 ½ pounds Brussels sprouts, trimmed and halved
- 1 medium butternut squash (about 2 pounds), peeled, seeded, and cut into ¾-inch cubes
- 1 cup fresh cranberries
- 3 tablespoons olive oil
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- 2 tablespoons pure maple syrup
- ½ cup chopped pecans
Equipment Needed
- Large rimmed baking sheet
- Parchment paper (optional, for easier cleanup)
- Large mixing bowl
- Sharp chef’s knife
- Cutting board
- Vegetable peeler
- Measuring cups and spoons
Instructions
Step 1: Prepare the Oven and Vegetables
Preheat your oven to 425°F. While the oven heats, prepare your vegetables. Rinse the Brussels sprouts under cool water. Trim off the dry stem ends, remove any loose or discolored outer leaves, and cut each sprout in half from top to bottom. For the butternut squash, use a sharp vegetable peeler to remove the tough outer skin. Cut the squash in half lengthwise and scoop out the seeds and stringy pulp with a spoon. Cut the squash halves into ¾-inch cubes. This size ensures the squash and Brussels sprouts will cook at a similar rate. Place the prepared Brussels sprouts and squash cubes in a large mixing bowl. Add the fresh cranberries to the bowl as well. This initial prep is the most active part of the recipe; everything else is largely hands-off roasting.
Step 2: Season and Toss
Pour 3 tablespoons of olive oil over the vegetables in the bowl. Sprinkle with 1 teaspoon of kosher salt and ½ teaspoon of freshly ground black pepper. Using your hands or a large spoon, toss everything thoroughly until every piece is lightly and evenly coated with the oil and seasoning. The oil is crucial as it helps conduct heat, promotes browning, and prevents sticking. Ensure the cut sides of the Brussels sprouts are facing up when you place them on the pan later, as this flat surface area will caramelize best. Tip: For an even more hands-off approach, you can toss the vegetables directly on the parchment-lined baking sheet to save washing the mixing bowl.
Step 3: Arrange and Roast
Line a large rimmed baking sheet with parchment paper for easy cleanup, if desired. Spread the seasoned vegetables out in a single, even layer. It is critical that the pieces are not crowded or piled on top of each other. Overcrowding will cause the vegetables to steam instead of roast, resulting in a soggy texture rather than crisp, caramelized edges. Place the baking sheet on the center rack of your preheated 425°F oven. Roast for 20 minutes. Do not stir or shake the pan during this initial roast. This allows the surfaces in contact with the hot pan to develop a deep, flavorful sear.
Step 4: Add Sweetness and Nuts
After 20 minutes, carefully remove the baking sheet from the oven. The vegetables should be starting to brown on the edges. Drizzle 2 tablespoons of pure maple syrup evenly over the vegetables. Sprinkle ½ cup of chopped pecans over the top. Using a spatula, gently toss and stir everything together, turning the vegetables to expose new surfaces to the heat. The maple syrup will glaze the vegetables and help the pecans toast. Spread everything back into an even layer. Tip: Toasting the pecans in a dry skillet for a few minutes before adding them can enhance their nutty flavor, but it’s not required as they will toast in the oven.
Step 5: Final Roast and Serve
Return the baking sheet to the oven. Continue roasting for another 15 to 20 minutes. Start checking at the 15-minute mark. The dish is done when the Brussels sprouts are tender with deeply browned, crispy leaves, the squash cubes are fork-tender and caramelized on the edges, and the cranberries have burst and become jammy. The pecans should be fragrant and lightly toasted. Total roasting time will be 35 to 40 minutes. Remove from the oven and let cool for 5 minutes on the pan before transferring to a serving dish. This brief rest allows the flavors to settle. Serve warm. Tip: For a finishing touch, a drizzle of balsamic glaze or a sprinkle of fresh thyme leaves just before serving adds a nice layer of complexity.
Tips and Tricks
For consistently sized squash cubes, cut the neck of the squash into rounds, then cube those rounds. The bulbous bottom can be cut into planks first. If using frozen cranberries, do not thaw them; add them directly from the freezer to prevent them from becoming too mushy too quickly. To make this dish ahead, you can chop the vegetables a day in advance. Store the chopped Brussels sprouts and squash separately in airtight containers in the refrigerator. The Brussels sprouts may develop a stronger odor if stored cut for too long. For extra crispy Brussels sprouts, ensure they are completely dry after washing before tossing with oil. Any residual water will promote steaming. If your oven has a convection setting, you can use it at 400°F; it may reduce cooking time by a few minutes and promote more even browning.
Recipe Variations
- Protein Addition: Add 12 ounces of diced chicken sausage or cubed tofu to the sheet pan at the beginning of roasting for a complete one-pan meal.
- Cheese Finish: After roasting, sprinkle with ¼ cup of crumbled goat cheese, feta, or shaved Parmesan while still warm. The residual heat will slightly melt the cheese.
- Spice It Up: Add ¼ teaspoon of crushed red pepper flakes or a pinch of cayenne pepper to the oil and salt seasoning for a subtle heat.
- Herb Swap: Instead of black pepper, toss the vegetables with 1 teaspoon of dried rosemary or thyme before roasting. Fresh herbs like sage or thyme can be added in the last 5 minutes of cooking.
- Sweet Potato Swap: Replace the butternut squash with an equal weight of sweet potatoes, peeled and cubed. The cooking time will be similar.
Frequently Asked Questions
Can I use frozen Brussels sprouts and squash? Yes, but results will differ. Frozen vegetables release more water. Roast them from frozen on a preheated pan at 425°F, but expect less caramelization and a slightly softer texture. You may need to extend the cooking time by 5-10 minutes.
How do I store and reheat leftovers? Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a 350°F oven for 10-15 minutes or in an air fryer for 5-7 minutes to restore crispiness. Microwaving will make the vegetables soft.
Can I make this recipe vegan? This recipe is naturally vegan as written. Ensure your maple syrup is pure maple syrup and not a blend with honey or other non-vegan ingredients. The optional cheese toppings in the variations would not be vegan.
My vegetables are browning too quickly. What should I do? If the edges are darkening before the centers are tender, the oven temperature may be too high or the rack position too high. Lower the temperature to 400°F, move the rack to a lower position, and loosely tent the pan with aluminum foil for the remainder of the cooking time.
What can I substitute for pecans? Walnuts, sliced almonds, or pumpkin seeds (pepitas) are excellent substitutes. Add them at the same time as the maple syrup so they toast without burning.
Summary
This sheet pan recipe delivers deep, caramelized flavor with minimal effort. Roasted Brussels sprouts and squash are balanced by tart cranberries and sweet maple syrup. It’s a versatile, crowd-pleasing side dish perfect for autumn meals.
