If you love brussels sprouts but also find yourself never being able to get them perfectly crispy on the outside and tender on the inside, rest assured you will learn everything you need to know in this recipe. Let’s get to it!

How to Make Oven-Roasted Brussels Sprouts with Garlic

Making brussels sprouts in the oven only requires a handful of ingredients you likely already have in your pantry and 15 minutes of cooking time. Below, find a quick overview of the recipe before you get to work.

  • Clean & Slice the Brussels: Using a sharp knife, slice the brussels in half, remove the wilted and tough outer layers, and rinse them under a colander.
  • Make the Marinade: In a large bowl, whisk together the lemon zest, lemon juice, pressed garlic cloves, olive oil, black pepper, and kosher salt.
  • Toss the Brussels: Toss the halved brussels sprouts in the marinade until evenly coated. Next, assemble them in a single layer on a rimmed baking sheet.
  • Bake the Brussels: In an oven heated to 420°F, bake the brussels for 15 minutes on the middle oven rack until they turn golden brown.
  • Top with Feta Cheese: Remove the brussels from the oven and immediately top them with crumbled feta cheese. Enjoy!

Tips & Tricks for Cooking Brussels Sprouts in the Oven

Below, find a couple of tips and tricks to help you make the best oven-roasted brussels sprouts.

  • Remove the tough and/or wilted outer leaves. Each brussels sprout will have a couple of tough or wilted layers that have a bland taste. After slicing, remove and toss them for best results.
  • Do not blanch or boil your brussels before roasting. Refrain from blanching or boiling your brussels before roasting them to prevent them from turning mushy.
  • Assemble the brussels in a single layer. For the crispiest brussels, lay them out in a single layer on the baking sheet and refrain from stacking them. Creating as much surface area as possible for the heat to hit them is key!
  • Play around with the seasonings. If you like a little extra tang, mix in some balsamic vinegar to your marinade. If feta cheese isn’t your thing, swap it from freshly grated parmesan cheese or goat cheese. Don’t be afraid to get creative!

Serving Brussels Sprouts

Eat brussels sprouts alongside your favorite protein for a well-rounded meal. A couple of great options include lamb shish kabobs, grilled ribeye steak, and one-pan roasted chicken and potatoes. You can also serve them as one of the many side dishes paired with your Thanksgiving turkey.

Storing Leftovers

  • Refrigerator: Store leftover brussels sprouts in an airtight container in the fridge. They should stay fresh for up to a week.
  • Freezer: Freeze leftover brussels sprouts by first letting them cool completely. Next, lay them in a single layer on a baking sheet lined with parchment paper. Once completely frozen, transfer them to a freezer-safe bag and store them for up to 6 months.

Reheating Tip: The best way to reheat refrigerated or frozen brussels sprouts is in a conventional oven or air fryer to return them to a crispy state. Refrain from microwaving them or they will turn out soggy.
