Swaps and Variations for Dietary Needs or Pantry Gaps

How to Make Roasted Crispy Parmesan Garlic Brussels Sprouts
- Preheat and Prep: Set your oven to 400°F. Clean and trim the Brussels sprouts. Halve them if large or leave whole for a “smashed” version.
- Season and Toss: In a large bowl, combine sprouts, minced garlic, olive oil, salt, pepper, and half of the Parmesan cheese. Toss to coat thoroughly.
- Roast the Sprouts: Spread the mixture in a single layer on a parchment-lined baking sheet, cut side down for maximum browning. Roast for 15 minutes.
- Flip and Roast Again: Stir or flip the sprouts and roast another 10–15 minutes, until fork tender and deeply golden.
- Add Cheese and Broil: Sprinkle remaining Parmesan on top and broil for 5–10 minutes, watching closely, until cheese is bubbling and crispy.
- Serve: Plate the Roasted Crispy Parmesan Garlic Brussels Sprouts immediately, or let them cool and serve at room temperature.
Pro Tips for the Best Crispy Brussels Sprouts
• Slice sprouts into quarters for extra crunch

• Don’t overcrowd the pan — space is key to crispiness
• Add bacon, honey drizzle, or lemon zest for a twist
• Use enough oil to coat the sprouts evenly
• Pre-shredded sprouts save time and still roast well
• For ultra-crispy results, finish under the broiler
• Use Panko breadcrumbs mixed with Parmesan before broiling for a crusty topping

Frequently Asked Questions
Can I make Roasted Crispy Parmesan Garlic Brussels Sprouts ahead of time?
Yes, you can prepare the ingredients up to two days in advance and store them in an airtight container in the refrigerator. Roast and broil them just before serving for the crispiest texture and freshest flavor.
Why aren’t my Brussels sprouts getting crispy in the oven?
To achieve that golden, crispy finish, make sure the sprouts are cut-side down on the baking sheet, spaced out in a single layer. Overcrowding traps steam and leads to sogginess. Also, use enough oil to coat them evenly, and don’t skip the broil step at the end.
Can I use frozen Brussels sprouts for this recipe?
While you can technically use frozen Brussels sprouts, they tend to release water during roasting and won’t crisp up like fresh ones. For the best texture and flavor, stick with fresh Brussels sprouts that are trimmed and halved.
