One of the best things about this Grilled Brussels Sprouts Foil Packets Recipe is how straightforward and minimal the ingredient list is. Each item plays a crucial role in bringing out the best taste, texture, and aroma of the sprouts, while keeping the cooking process stress-free and approachable.

  • ½ pound Brussels sprouts: Fresh and halved for even grilling and the perfect tender-crisp bite.
  • ½ yellow onion: Sliced thickly to add a subtle sweetness and complement the savory sprouts.
  • 2 tablespoons olive oil: Helps to coat the veggies evenly, promoting caramelization and adding richness.
  • 1 teaspoon garlic powder: Delivers a warm, fragrant depth without overpowering the fresh flavors.
  • ½ teaspoon salt: Enhances natural flavors and balances the sweetness of the onion.
  • Freshly ground pepper: Adds a little gentle heat and complexity, sprinkled to taste.

How to Make Grilled Brussels Sprouts Foil Packets Recipe

Step 1: Prep Your Grill and Veggies

Start by preheating your grill to about 400 degrees Fahrenheit; this hot temperature will ensure a lovely char while keeping the insides tender. Meanwhile, give your Brussels sprouts a good rinse and pat them completely dry. Drying is key because moisture will steam the sprouts rather than grill them, and we want that irresistible grilled texture.

Step 2: Toss the Brussels Sprouts and Onions

In a large bowl, combine the halved Brussels sprouts with the thick slices of yellow onion. Drizzle in the olive oil, sprinkle on the garlic powder, salt, and freshly ground pepper. Toss everything together until the veggies are thoroughly coated—this step ensures every bite is flavorful and juicy.

Step 3: Prepare the Foil Packets

Lay out a large sheet of heavy-duty aluminum foil and add the tossed vegetables in an even layer. Cover with a second large piece of foil and seal the edges by folding carefully to create a packet. Don’t forget to poke a small hole in the top with a fork or knife to let steam escape—this little vent balances the cooking environment perfectly.

Step 4: Grill to Perfection

Place the foil packets directly over the heat on your grill. Let the Brussels sprouts and onions cook for 20 to 25 minutes, turning the packets occasionally if needed. You’ll know they’re ready when the sprouts are tender and have a yummy, slightly charred aroma wafting through the air. The foil locks in moisture while adding intimate smoky grill flavor—pure magic!

The main layer is made up of vibrant green Brussels sprouts, halved to show their leafy texture and light toasted edges in tan and brown. Beneath and mixed among them are thick slices of translucent white onions with some light golden and charred spots. The vegetables are scattered unevenly, giving a rustic and well-roasted look. The foil itself has a few dark brown burnt spots and wrinkles around the edges. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

Fresh herbs like chopped parsley or a sprinkle of lemon zest can brighten these grilled Brussels sprouts beautifully and add a fresh contrast to their smoky flavor. A final drizzle of balsamic glaze or a sprinkle of grated Parmesan also takes them to the next level if you want a little extra flair.

Side Dishes

This Grilled Brussels Sprouts Foil Packets Recipe pairs wonderfully with grilled meats like chicken, steak, or fish, but it’s just as fantastic alongside veggie burgers or a hearty quinoa salad. The smoky, savory flavor holds up well and complements a variety of barbecue plates effortlessly.

Creative Ways to Present

For a fun twist, serve the grilled sprouts and onions directly in their foil packet for a rustic presentation that keeps everything warm at the table. Alternatively, pile them atop toasted baguette slices with a smear of goat cheese for an impressive appetizer that will have everyone asking for seconds.

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftovers (though that’s rare!), transfer them to an airtight container and keep them refrigerated for up to 3 days. The flavors meld nicely overnight, making the sprouts even tastier the next day.

Freezing

While freezing is possible, it’s not ideal for maintaining the best texture since Brussels sprouts can become mushy when thawed. If you must freeze, cool completely, place in a freezer-safe container or bag, and consume within 1 month for best results.

Reheating

To reheat, unwrap the foil packet and warm the sprouts gently in a 350-degree oven for about 10 minutes or until heated through. You can also toss them back on the grill for a few minutes to revive that fresh grilled char and crispness.

FAQs

Can I make this recipe without a grill?

Absolutely! You can roast these Brussels sprouts foil packets in the oven at 400 degrees Fahrenheit for about 20-25 minutes. The oven will caramelize and soften the veggies similarly, though you’ll miss out on the smoky grill flavor.

Do I need to use foil packets? Can I grill them in a basket or directly on the grates?

Foil packets are great for keeping the sprouts moist and infusing flavor while making clean-up easy. You can use a grill basket, but the sprouts might cook faster and char differently. Direct grilling without protection risks burning and losing small sprouts through the grates.

How can I add some heat to this recipe?

Simple! Toss in a pinch of crushed red pepper flakes or a dash of cayenne pepper when seasoning the sprouts. This adds a balanced kick that complements the smokiness perfectly.

Are these Brussels sprouts vegan and gluten-free?

Yes, this Grilled Brussels Sprouts Foil Packets Recipe is entirely plant-based and naturally gluten-free, making it perfect for a variety of dietary needs and lifestyle choices.

Can I double the recipe for a larger group?

Definitely. Just increase the amounts of ingredients accordingly and create multiple foil packets. Make sure not to overcrowd the packets so the heat circulates properly and everything cooks evenly on the grill.

Final Thoughts

This Grilled Brussels Sprouts Foil Packets Recipe takes a humble vegetable and transforms it into a flavorful, easy side that will impress family and friends. Its simple ingredients and fuss-free technique mean anyone can nail it, even if you’re not a grill master. Next time your grill heats up, give this recipe a try—I promise it will become a delicious habit you look forward to every grilling season!

  • ½ yellow onion, cut into thick slices

Seasonings & Oils

  • 2 tablespoons olive oil
  • 1 teaspoon garlic powder
  • ½ teaspoon salt, plus more to taste
  • Freshly ground black pepper, to taste


Instructions

  1. Preheat Grill: Preheat your grill to 400 degrees Fahrenheit to prepare for cooking your Brussels sprouts in foil packs.
  2. Prepare Brussels Sprouts and Onions: Wash the Brussels sprouts thoroughly and pat them dry. Cut the Brussels sprouts in half and slice the yellow onion into thick pieces.

  4. Assemble Foil Pack: Place the seasoned Brussels sprouts and onions onto a large piece of heavy-duty aluminum foil. Cover with another large piece of foil and tightly seal the edges by folding the foil together, creating a secure packet.
  5. Poke Vent Hole: Use a fork or knife to carefully puncture a hole at the top of the foil pack to allow steam to escape during grilling.
  6. Grill Vegetables: Place the foil packet directly over the heat on the preheated grill. Grill for 20-25 minutes, flipping once halfway through if desired, until the Brussels sprouts are tender and have a slight char.
