Ingredients

• 8 ounces (225g) frozen Brussels sprouts — Look for whole or halved sprouts that are firm and free from freezer burn.
• 2 tablespoons extra virgin olive oil — Use a good quality olive oil for the best flavor and health benefits.
• Salt and pepper to taste — Freshly ground black pepper and sea salt or kosher salt work beautifully.

How To Make Roasted Frozen Brussels Sprouts

Step 1: Preheat Your Oven

Preheat your oven to 425°F (220°C). A high temperature is key to achieving that crispy, caramelized exterior on the Brussels sprouts.

Step 2: Prepare the Brussels Sprouts

Take your frozen Brussels sprouts straight from the freezer — no need to thaw. Place them in a large mixing bowl.

Step 3: Toss with Olive Oil and Seasoning

Drizzle the olive oil over the frozen Brussels sprouts, then sprinkle with salt and freshly ground black pepper. Toss well to ensure every sprout is evenly coated with oil and seasoning.

Step 4: Arrange on a Baking Sheet

Spread the Brussels sprouts out in a single layer on a rimmed baking sheet. Make sure they have some space between them to allow for even roasting and crisping.

Step 5: Roast the Brussels Sprouts

Place the baking sheet in the preheated oven. Roast for about 25-30 minutes, stirring or shaking the pan halfway through cooking to promote even browning. The Brussels sprouts should be golden brown and crispy on the edges when done.

Step 6: Serve Immediately

Once perfectly roasted, transfer the Brussels sprouts to a serving dish. Taste and adjust seasoning with a little more salt and pepper if needed. Serve hot and enjoy the crispy, flavorful goodness!

Expert Tips

• Don’t overcrowd the pan: Give the Brussels sprouts plenty of room on the baking sheet to ensure they roast rather than steam.
• Use high heat: Roasting at 425°F (220°C) helps to caramelize the natural sugars and get that satisfying crisp texture.
• Turn halfway through: Stirring or shaking the pan around the halfway point promotes even browning and prevents burning.
• Choose quality olive oil: Since this recipe is simple, the olive oil’s flavor really shines through. Use extra virgin olive oil for the best taste.
• Season generously: Salt brings out the flavor and helps with caramelization, so don’t be shy with it.

Variations and Customizations

• Add garlic: Toss in 2-3 minced garlic cloves with the olive oil before roasting for a fragrant, savory twist.
• Lemon zest and juice: Brighten the dish by adding fresh lemon zest and a squeeze of lemon juice after roasting.
• Parmesan cheese: Sprinkle grated Parmesan cheese over the hot Brussels sprouts right after roasting for a cheesy, salty finish.
• Spicy kick: Add a pinch of red pepper flakes or a dash of cayenne pepper to the olive oil for some heat.
• Balsamic glaze: Drizzle balsamic reduction over the roasted sprouts for a sweet and tangy contrast.
• Herbs: Fresh herbs like thyme, rosemary, or parsley can be tossed in after roasting for added freshness and aroma.

How to Store Leftovers

If you have leftovers, let the roasted Brussels sprouts cool completely before storing. Place them in an airtight container and refrigerate for up to 3-4 days. To reheat, spread them out on a baking sheet and warm in a 375°F (190°C) oven for about 10 minutes until heated through and crispy again. Avoid microwaving if possible, as this can make them soggy. You can also add leftover Brussels sprouts to salads, grain bowls, or omelets for quick meals.

FAQ

Can I use fresh Brussels sprouts instead of frozen?

Absolutely! If using fresh Brussels sprouts, trim the ends and halve them before roasting. The roasting time may be slightly shorter, around 20-25 minutes. The method is essentially the same and just as delicious.

Do I need to thaw the frozen Brussels sprouts before roasting?

No need to thaw! Roasting them straight from frozen helps maintain their texture and prevents sogginess. Just be sure to toss them well with olive oil and spread them out on the baking sheet.

Can I use a different oil for roasting?

Yes, you can substitute extra virgin olive oil with other oils that have a high smoke point, such as avocado oil or grape seed oil. However, olive oil adds a lovely flavor that complements Brussels sprouts beautifully.

How do I get the Brussels sprouts extra crispy?

To get them extra crispy, make sure to roast at a high temperature (425°F/220°C) and avoid overcrowding the pan. Tossing them halfway through cooking helps too. If you want even crispier edges, you can finish with a quick broil for 1-2 minutes, but watch carefully to avoid burning.
