How to Roast Brussels Sprouts and Asparagus
Step 1 — Preheat: Preheat the oven to 450°F (about 230°C). A hot oven helps the sprouts develop a crisp, caramelized exterior.
Step 2 — Prepare the vegetables: Wash and dry the vegetables thoroughly — less surface moisture yields better browning. Quarter the Brussels sprouts. Trim the tough asparagus ends and cut spears into uniform pieces if desired.
Step 3 — Season the sprouts: Place the quartered sprouts in a bowl. Grate or quickly shave about 2 tablespoons of very cold butter over them (using cold butter helps it cling and create crisping). Add about 1/4 tsp salt and toss to coat.
Step 4 — Roast the sprouts: Arrange the sprouts in a single layer on a large baking sheet so they have room to brown. Roast at 450°F for 10–13 minutes, stirring once or twice so the edges brown evenly.
Step 5 — Add asparagus and almonds: While the sprouts roast, coat the asparagus with the remaining grated butter and a pinch of salt. When the sprouts have roasted 10–13 minutes, remove the pan, add the asparagus and sliced almonds, toss, reduce the oven to 400°F, and return to roast another 8–12 minutes until the asparagus is tender and the sprouts are golden. For extra browning, broil for 30–60 seconds at the end, watching closely so nothing burns.
Step 6 — Make the sauce: Whisk together the lemon juice, Dijon mustard and maple syrup with a pinch of salt until smooth. Taste and adjust the balance of sweet, tangy and salty to your preference.
Serve: Transfer the roasted vegetables to a serving platter, drizzle generously with the maple-Dijon sauce and sprinkle any extra toasted almonds on top. The dressing brightens the dish and balances the roasted flavor.
Tips for Perfect Roasted Brussels Sprouts and Asparagus
- Keep the oven hot (440–450°F) to promote browning instead of steaming.
- Quarter or halve sprouts so more flat surface touches the pan for better caramelization.
- Broil briefly at the end (30–60 seconds) if you want deeper charring — monitor closely.
- Choose smaller sprouts for a sweeter, less bitter flavor.
- Roast asparagus only until just tender to retain its bright green color and texture.
- If using frozen sprouts, roast longer to evaporate extra moisture and achieve crispiness.
Variations and Add-Ins
- Garlic & balsamic: Add minced garlic in the last 8–10 minutes of roasting and finish with a splash of good balsamic before serving.
- Bacon & mushrooms: Stir in chopped cooked bacon or sauteed mushrooms for a heartier flavor.
- Make it a meal: Add roasted sweet potato, carrots, cooked grains or beans to turn this into a complete main course.
- Sweet crunch: Toss in dried cranberries, cherries, or other nuts and seeds for texture and sweetness.
Serving Suggestions
This side pairs well with roasted or grilled chicken, pork, meatballs, or a grain bowl. It also complements vegetarian mains like stuffed mushrooms or a hearty grain salad.
