These crispy Brussels sprouts chips are about to become your new obsession, and honestly, you might want to hide them from yourself because they disappear faster than regular potato chips.

The secret is slicing them paper-thin and roasting them until they’re golden and crispy, transforming humble Brussels sprouts into an addictive snack that even vegetable skeptics will devour.

You’ll get that perfect combination of crispy edges and tender centers, with a nutty flavor that’s enhanced by garlic powder and a hint of Parmesan cheese.

This recipe proves that healthy snacking doesn’t have to be boring – these chips deliver all the satisfying crunch you crave with a fraction of the calories.

The best part is how simple they are to make: just slice, season, and bake until golden, then try not to eat the entire batch straight from the pan.

Fair warning though – once you master this technique, you’ll find yourself buying Brussels sprouts by the pound and wondering why anyone bothers with regular chips.

Ingredients

For the Brussels Sprouts Chips

½ pound Brussels sprouts, firm and bright green
1 tablespoon extra virgin olive oil, plus additional as needed
½ teaspoon garlic powder (optional but recommended)
½ teaspoon kosher salt
¼ teaspoon ground black pepper
1 tablespoon finely grated Parmesan cheese (optional)

Instructions

Preparation

1 Position a rack in the upper third of your oven and preheat to 400°F (200°C). Generously coat a rimmed baking sheet with nonstick spray. If you’re doubling the recipe, place one rack in the upper third and one in the lower third, then grease 2 baking sheets for optimal air circulation.
2 Trim off a small portion of the stem end from each Brussels sprout using a sharp knife. Using a mandoline slicer or sharp knife, carefully slice the Brussels sprouts lengthwise from tip to stem into thin, uniform slices about ⅛-inch thick. The mandoline slicer ensures consistent thickness for even cooking. If leaves separate during slicing, discard any brown or damaged ones but keep the larger green leaves – they’ll become extra crispy and delicious. Transfer sliced Brussels sprouts to a large mixing bowl as you work.

Seasoning and Coating

3 Add the extra virgin olive oil, garlic powder, kosher salt, and black pepper to the bowl with the sliced Brussels sprouts. Using your hands or tongs, toss thoroughly to ensure every piece is evenly coated with oil and seasonings. The Brussels sprouts should glisten with oil – add an additional ½ tablespoon olive oil if needed to prevent burning and ensure crispy results.

Baking Process

4 Spread the seasoned Brussels sprouts in a single layer on the prepared baking sheet, ensuring pieces don’t overlap. Overcrowding leads to steaming rather than crisping. Bake for 10 minutes until the edges begin to turn golden brown.
5 Remove the pan from the oven and use a silicone spatula to flip and redistribute the Brussels sprouts, promoting even browning on all sides. Spread them back into a single layer and sprinkle with Parmesan cheese if using. Return to the oven and continue baking for 5 additional minutes until they’re deeply golden and crispy. If using two pans, switch their rack positions at this point for uniform cooking. Watch carefully during the final minutes to prevent burning – they can go from perfectly crispy to burnt very quickly.

Recommended Equipment and Kitchen Tools

Recommended Tools (for best results)

Mandoline slicer – Creates uniform thin slices that cook evenly, resulting in consistently crispy chips rather than a mix of burnt and undercooked pieces
Rimmed baking sheet – The raised edges prevent Brussels sprouts from sliding off while allowing proper air circulation for maximum crispiness
Large mixing bowl – Provides adequate space for thoroughly coating all Brussels sprouts with oil and seasonings without spillage
Silicone spatula – Won’t scratch your baking sheet and makes flipping delicate Brussels sprouts easier than metal tools

Helpful Upgrades

Kitchen scale – Measuring Brussels sprouts by weight (½ pound) rather than estimating ensures consistent results every time you make this recipe
Parchment paper – While nonstick spray works, parchment paper provides foolproof release and easier cleanup, especially important with cheese

Nice-to-Have Options

Microplane grater – Creates the finest Parmesan cheese texture that adheres better to the Brussels sprouts and melts more evenly
Tongs – Useful for tossing Brussels sprouts with seasonings and flipping them during baking without breaking delicate pieces

It’s suitable for most dietary restrictions and provides a satisfying crunch without processed ingredients. The high fiber content promotes satiety and digestive health, making these chips a smart alternative to traditional snack foods.

Smart Swaps and Ingredient Substitutions

Common Substitutions:

Extra virgin olive oil → Avocado oil (1:1 ratio) for higher smoke point and neutral flavor, or melted coconut oil for subtle sweetness
Garlic powder → Fresh minced garlic (1 clove) mixed with oil, though powder distributes more evenly
Kosher salt → Sea salt or Himalayan pink salt (same amount) for different mineral profiles

Budget-Friendly Swaps:

Parmesan cheese → Pecorino Romano or aged Asiago for similar sharp, nutty flavors at lower cost
Extra virgin olive oil → Regular olive oil or vegetable oil, though you’ll lose some flavor complexity
Fresh Brussels sprouts → Frozen Brussels sprouts (thawed and patted dry), though texture will be slightly less crispy

Pantry Emergency Substitutions:

Garlic powder → Onion powder or Italian seasoning for different but complementary flavors
Black pepper → White pepper or red pepper flakes for heat variation
Parmesan → Aged cheddar (finely grated) or nutritional yeast for cheese-like flavor

Pro Tips for Substitutions:

Store grated Parmesan in the freezer to prevent clumping and extend shelf life
When using fresh garlic instead of powder, add it during the last 5 minutes of baking to prevent burning

Pro Tips and Troubleshooting

Professional Techniques

Use a mandoline slicer set to ⅛-inch thickness for restaurant-quality uniformity – inconsistent slicing leads to uneven cooking with some pieces burning while others remain chewy. Pat Brussels sprouts completely dry after washing and before slicing to prevent steaming during roasting. Don’t skip the oil coating – every piece needs to glisten with oil to achieve maximum crispiness and prevent burning.

Common Mistakes and Solutions

Overcrowding the pan is the biggest culprit behind soggy chips. Brussels sprouts need space for air circulation – use two pans if necessary rather than cramming everything onto one sheet. Skipping the flip at the 10-minute mark results in uneven browning. Opening the oven door frequently releases heat and extends cooking time, so resist the urge to check constantly.

Storage and Make-Ahead

These chips are best enjoyed immediately while at peak crispiness, but leftovers can be stored in an airtight container for up to 2 days. Recrisp in a 350°F (175°C) oven for 3-5 minutes before serving. Make-ahead prep: Slice Brussels sprouts up to 4 hours in advance and store in the refrigerator, then season and bake when ready to serve.

Recipe Scaling

When doubling, use two baking sheets and rotate positions halfway through baking for even results. For larger batches, stagger baking times by 5 minutes to manage multiple pans effectively without losing track of doneness.

These Brussels sprouts chips prove that healthy snacking can be just as satisfying as reaching for a bag of regular chips, and once you experience that perfect combination of crispy texture and savory flavor, you’ll understand why they’re destined to become your new favorite guilt-free indulgence.
