Crispy Oven-Roasted Brussels Sprouts with Garlic and Parmesan

This easy oven-roasted Brussels sprouts recipe delivers perfectly crispy, caramelized sprouts every time. Roasted with a whole head of garlic, onion, olive oil, and simple seasonings, these sprouts make a versatile side that’s great year-round — from weeknight dinners to holiday spreads.

If your first Brussels sprouts experience involved overcooked, mushy frozen vegetables, try fresh sprouts roasted in the oven — the difference is dramatic. Roasting concentrates sweetness and produces browned, slightly crisp edges while keeping the centers tender. For even cooking, cut sprouts to roughly the same size and give them space on the sheet pan so hot air can circulate. Once prepped, this recipe is mostly hands-off: toss with oil and spices, then let the oven do the work.

What You Need for Oven Roasted Brussels Sprouts

These flavorful roasted Brussels sprouts use fresh, simple ingredients:

• Brussels sprouts (fresh)
• Head of garlic
• Onion (minced)
• Olive oil
• Salt and pepper
• Garlic powder

Oven Roasted Brussels Sprouts Variations

Roasted Brussels sprouts are a fantastic base for experimenting. Try one of these simple variations to change the flavor profile:

• Oil choices: Olive oil gives classic flavor and helps the sprouts caramelize. For a milder or slightly sweeter note, use avocado oil or coconut oil respectively. Don’t skimp — the oil is key to crisp, browned edges.
• Seasoning blends: Keep it simple with salt, pepper, and garlic powder, or switch to a spice blend. Two tasty options are a curry-turmeric mix (about 2 teaspoons curry powder + 1/2 teaspoon turmeric + a pinch of salt) or a savory taco-style seasoning.
• Balsamic finish: Toss roasted sprouts with a splash of balsamic vinegar for a sweet, tangy glaze.
• With bacon: Add cooked, crumbled bacon for a smoky, savory element.
• Cheesy: Sprinkle 1/4 cup grated Parmesan over the sprouts about halfway through roasting for a nutty, salty finish.

Storage

These roasted Brussels sprouts keep well and make excellent leftovers. Once completely cooled, store them in an airtight container in the refrigerator for up to 5 days.

Best ways to reheat:

• Stovetop: Heat a little olive oil in a skillet over medium. Add the sprouts and sauté about 4–6 minutes until heated through and crisped up.
• Oven: Spread sprouts on a baking sheet and warm in a 350ºF oven for about 10 minutes.

Make Ahead

Trim, wash, and dry sprouts up to 2 days in advance and store them in an airtight container in the fridge. When ready to roast, finish the recipe as written.

Serving Suggestions

Oven-roasted Brussels sprouts are a holiday favorite but also shine year-round. Serve them as a side for roasted or grilled meats, toss them into grain bowls, or add them to breakfast scrambles. They pair particularly well with roasted chicken thighs, stuffed pork chops, or a simply seared steak. For a vegetarian option, add them to a harvest grain bowl for texture and savory depth.

By: Lee Funke

Prep: 15 mins • Cook: 30 mins • Total: 45 mins • Servings: 6

Ingredients

• 2 lbs. Brussels sprouts
• 1 head garlic
• 1/2 medium white onion, minced
• 3 tablespoons olive oil
• 1/8 teaspoon salt, or more to taste
• 1/4 teaspoon ground pepper
• 1/2 tablespoon garlic powder

Instructions

1. Preheat the oven to 400ºF. Line a baking sheet with parchment paper or aluminum foil, or spray the pan lightly with nonstick spray.
2. Prepare the Brussels sprouts and garlic: rinse sprouts under warm water, pat dry, trim the stem ends, and halve them lengthwise. If some sprouts are much larger, quarter them so pieces are uniform. Trim the top of the garlic head so the cloves are exposed but the bulb stays intact. Place sprouts and garlic on the prepared baking sheet.
3. Add the minced onion to the baking sheet with the sprouts.
4. Drizzle olive oil over the sprouts and onion. Sprinkle with salt, pepper, and garlic powder. Use your hands to toss and evenly coat all pieces with oil and seasonings.
5. Arrange sprouts cut-side down and spread them so they are not touching; do not overcrowd the pan. Place the garlic head cut-side down on the pan.
6. Bake 25–30 minutes, tossing the sprouts and flipping the garlic head every 10 minutes. The sprouts are done when browned and crispy at the edges and tender inside.
7. Let cool about 10 minutes. Squeeze the roasted garlic cloves from their skins and toss the softened garlic into the sprouts before serving.

Tips & Notes

• Storage: Store leftover sprouts in an airtight container in the refrigerator for up to 5 days.
• Reheating: Reheat on the stovetop with a little olive oil for best texture, or warm in a 350ºF oven for about 10 minutes. The microwave can be used in a pinch, but the texture will be softer.
• Make ahead: Wash, trim, and dry sprouts up to 2 days before roasting and refrigerate until ready to use.
• Customizations: Add a splash of balsamic vinegar after roasting, stir in crumbled bacon, or top with grated Parmesan for extra flavor.
