Oven Roasted Brussels Sprouts Recipe

As a recipe developer, I finally cracked an oven roasted Brussels sprouts method that yields crispy results every time using simple Halved Brussel Sprouts and only 10 minutes of prep.

I used to think Brussels sprouts were boring, until I found a way to make them sing in the oven. I love tossing them with olive oil and a sprinkle of grated Parmesan cheese then letting heat work its magic.

It sounds simple but the result is this addictive mix of char and crunch that makes you want more. I’ve tried Skillet Roasted Brussel Sprouts, and even Halved Brussel Sprouts methods, but this version keeps the edges dark and the insides tender.

I can’t promise you’ll stop at one serving, and honestly sometimes I dont either.

Ingredients

• Crunchy little cabbages, high in fiber and vitamin C, good for digestion and fullness
• Adds richness and browning, mostly healthy fats, helps absorb vitamins, tastes nutty
• Brings out natural flavors, helps crisp edges, use sparingly if your watching sodium
• Gives mild heat and aroma, pairs well with lemon and cheese, simple kick
• Garlic adds savory depth and aroma, can be sharp raw or mellow roasted
• Adds tangy sweet notes, helps caramelize and balances bitterness, a little goes far
• Salty umami finish, gives nutty savory boost and crisp brown bits when roasted

Ingredient Quantities

• 1 1/2 pounds Brussels sprouts, trimmed and halved
• 2 tablespoons olive oil or avocado oil
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon garlic powder or 2 cloves garlic, minced
• 1 tablespoon balsamic vinegar, optional
• 2 tablespoons grated Parmesan cheese, optional
• 1 tablespoon lemon juice, optional

How to Make this

1. Preheat oven to 425°F (220°C) and place a rimmed baking sheet in the oven while it heats so it’s hot when the sprouts hit it.

2. Trim ends off the 1 1/2 pounds Brussels sprouts, cut them in half through the stem, and pat them very dry with a towel — wet sprouts steam instead of crisp.

3. In a large bowl toss the halved sprouts with 2 tablespoons olive or avocado oil, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and 1/2 teaspoon garlic powder or the minced 2 garlic cloves until evenly coated.

4. Spread the sprouts cut-side down in a single layer on the hot rimmed sheet; do not crowd them. Use two pans if needed so air can circulate and they can crisp.

5. Roast for 20 to 25 minutes until deep golden brown and crispy on the edges; flip or shake the pan once about halfway through if you want more even browning.

6. If your oven has a convection setting use it and check early; convection usually speeds things up and gives extra crisp.

7. For balsamic glaze, either drizzle 1 tablespoon balsamic vinegar over the sprouts in the last 2 minutes and return to oven to caramelize, or toss with it off the heat for a fresher tang — both work, your choice.

8. Remove from oven, immediately toss with 1 tablespoon lemon juice and 2 tablespoons grated Parmesan if using, taste and add a pinch more salt or pepper if needed.

9. Let sit a minute or two so the cheese melts just a bit, then transfer to a serving bowl. Theyre best hot and crispy so serve right away.

10. Quick tips: dry them well, cut-side down = better browning, dont overcrowd, and a hot pan equals crunch. Enjoy.

Equipment Needed

1. Rimmed baking sheet, preheated in the oven (use two if you need more room)
2. Parchment paper or silicone baking mat, optional for easier cleanup
3. Sharp chef’s knife to trim and halve the sprouts
4. Cutting board
5. Large mixing bowl to toss sprouts with oil and seasonings
6. Measuring spoons for oil, salt, pepper and garlic
7. Clean kitchen towel or paper towels to pat sprouts very dry
8. Spatula or tongs to spread, flip or shake the pan
9. Oven mitts or potholders and a serving bowl for plating

Oven Roasted Brussels Sprouts Recipe Substitutions and Variations

• Olive oil or avocado oil: swap with melted butter or ghee (same amount) for a richer, nutty flavor, or use grapeseed/canola oil if you want a neutral oil with a higher smoke point.
• Kosher salt: use fine sea salt or table salt but cut the amount down since those are saltier — start with about half to three quarters of the listed amount and taste.
• Garlic powder or fresh garlic: try 1 teaspoon jarred minced garlic, 1/2 teaspoon onion powder, or a tablespoon of roasted garlic for a sweeter, mellow garlic note.
• Grated Parmesan cheese: swap with Pecorino Romano or Asiago for a sharper, saltier bite, or use nutritional yeast for a dairy free, cheesy flavor.

Pro Tips

1) Dry them like crazy before they hit the pan. I pat them with a towel and let them sit a few minutes, wet sprouts steam not crisp so this is the biggest game changer, trust me.

2) Heat the baking sheet in the oven first so the sprouts get an instant sear when they meet it. If your pan is too crowded use a second sheet, otherwise theyll steam instead of browning.

3) Arrange the sprouts cut side down and dont flip them a million times. A single flip or a quick shake about halfway through gives the best deep golden color and crispy edges.

4) Brighten and finish off after they come out of the oven. Toss with lemon or a splash of balsamic and sprinkle the Parmesan right at the end so the acid pops and the cheese melts just enough without burning.
