VEGAN Crispy Garlic Parmesan Brussels Sprouts Recipe

Hey! If you love crispy, garlicky little green bombs of joy, you’re in the right place. I made this vegan version of Crispy Garlic Parmesan Brussels Sprouts because someone (me) refused to believe “vegan parmesan” couldn’t be just as satisfying as the real thing. Spoiler

Ingredients
  

  • Ingredients for Crispy Garlic Parmesan Brussels Sprouts
  • I kept this simple and pantry-friendly. Bold the essentials? Done.
  • 1 pound Brussels sprouts trimmed and halved
  • 3 tablespoons olive oil or avocado oil if you want higher smoke point
  • 4 cloves garlic minced (fresh = better)
  • 1 teaspoon salt adjust to taste
  • ½ teaspoon black pepper
  • 1 teaspoon Italian seasoning or a pinch of oregano + basil
  • ½ cup vegan Parmesan see quick recipe below
  • Zest of 1 lemon adds brightness
  • Optional: red pepper flakes for heat
  • Vegan Parmesan quick homemade version — totally optional but I recommend it
  • 3/4 cup raw cashews soaked 15–30 minutes if you want an ultra-fine powder
  • 3 tablespoons nutritional yeast
  • 1/2 teaspoon fine salt
  • Zest of 1/2 lemon optional, but yum
  • Pulse in a food processor until crumbly-fine. Store leftovers in the fridge.
  • FYI: You can use store-bought vegan Parmesan if you’re short on time.

Equipment

  • Mixing bowl (large)
  • Baking sheet (rimmed)
  • Parchment paper (or a reusable silicone mat)
  • Oven (set to 400°F / 200°C)
  • Sharp knife and cutting board
  • Measuring spoons
  • Spatula or tongs
  • Food processor (optional — for vegan Parmesan)

Method
 

  1. I keep my steps friendly and direct. You can do this.
  2. Preheat the oven to 400°F (200°C). Line your baking sheet with parchment. Don’t skip lining — cleanup wins lives.
  3. Prep the sprouts. Trim the stem ends and halve each sprout. If a sprout looks huge, quarter it so everything cooks evenly.
  4. Mix flavor. In your large mixing bowl, combine the sprouts, olive oil, minced garlic, salt, pepper, and Italian seasoning. Toss until every piece glistens. Want them extra crispy? Use slightly less oil and make sure the sprouts stay dry before oiling.
  5. Spread on the sheet. Arrange sprouts cut-side down in a single layer. Overcrowding? That makes them steam, not roast. Don’t overcrowd. Seriously.
  6. Roast for 25–30 minutes, flip once halfway (around 12–15 minutes) so both sides crisp. Watch the edges — you want deep golden-brown, not charcoal.
  7. Finish immediately. Pull the tray, sprinkle with the vegan Parmesan and lemon zest while still hot, and toss gently so the heat melds the flavors. Add red pepper flakes if you like a little drama.
  8. Serve hot. Eat right away for best crunch. Leftovers lose crispness fast, but I’ll tell you how to rescue them below.
  9. Hacking extra crispiness — pro-ish tips
  10. Want a sprout that crunches loud enough to annoy someone in the next room? Try these:
  11. Cut-side down = instant caramelization. Don’t fight the law of roast.
  12. Dry sprouts = crisp sprouts. After washing, dry thoroughly. I pat them with a towel. No one wants water in their crunch.
  13. Space them out. Single layer, remember? Give them breathing room.
  14. Don't stir too often. Flip once. Repeated poking loses heat.
  15. High heat works. 400°F is my happy place for these. If you want extra browning, bump to 425°F and shave a few minutes off the time. Watch closely.
  16. Use cornstarch (optional): Toss sprouts lightly in 1 tablespoon cornstarch before oiling for an ultra-crisp exterior. Yes, it works.

Notes

Variations & swaps — because life is full of choices

  • Air fryer: Roast at 375°F (190°C) for 12–15 minutes, shaking the basket halfway.
  • Pan-seared: Heat a skillet with oil and sear cut-side down until brown, then add a splash of water and cover for a minute to cook through. Uncover and crisp again.
  • Add nuts: Toss with toasted pine nuts or sliced almonds for texture.
  • Make it smoky: Add a pinch of smoked paprika or swap half the olive oil for a little bacon-flavored vegan crumble (if you’re into that).
  • Make it low-oil: Spray lightly with oil or use 2 tbsp oil and roast a little longer. Still tasty.
