Ingredients
- Brussels Sprouts: 1.5 pounds, look for firm, bright green sprouts of similar size. Brussels sprouts are packed with vitamins C and K, as well as fiber. Smaller sprouts tend to be sweeter and more tender. If you can’t find fresh Brussels sprouts, frozen can be used in a pinch, but be sure to thaw and thoroughly dry them before roasting.
- Pancetta: 4 ounces, diced. Pancetta, Italian cured pork belly, offers a wonderful salty, savory flavor. If you can’t find pancetta, bacon (thick-cut is preferable) or even prosciutto can be used as a substitute.
- Walnuts: ½ cup, roughly chopped. Walnuts provide a satisfying crunch and nutty flavor. To enhance their flavor, toast them lightly in a dry pan or oven before adding them to the Brussels sprouts. Pecans or hazelnuts can also be used.
- Olive Oil: 2 tablespoons, extra virgin. Olive oil is essential for roasting, providing moisture and helping the Brussels sprouts caramelize beautifully.
- Garlic: 2 cloves, minced. Garlic adds a pungent aroma and flavor. Use fresh garlic for the best results.
- Balsamic Vinegar: 1 tablespoon, good quality. Balsamic vinegar adds a touch of sweetness and acidity, balancing the savory flavors.
- Maple Syrup: 1 teaspoon (optional). A tiny bit of maple syrup enhances caramelization and adds a subtle sweetness. This is optional but recommended!
- Salt and Pepper: To taste. Seasoning is key! Don’t be shy with the salt and pepper, as they bring out the flavors of all the ingredients.
- Red Pepper Flakes: ¼ teaspoon (optional). For a touch of heat, add a pinch of red pepper flakes.
Ingredient Science & Substitution Tips: Roasting Brussels sprouts brings out their natural sugars, leading to caramelization and a sweeter flavor. The pancetta adds fat and salt, which further enhances the sprouts’ natural flavors. Walnuts provide healthy fats and a satisfying crunch. If you’re looking for a vegetarian option, omit the pancetta and add a sprinkle of smoked paprika for a similar smoky flavor. Nutritional yeast can also be added for a cheesy, umami-rich flavor.
Expert Tips for Perfect Brussels Sprouts
Here are some of my expert tips, gathered from years of making this recipe:
- Don’t overcrowd the pan: Overcrowding will steam the Brussels sprouts instead of roasting them. Use a large baking sheet or two smaller ones.
- Preheat the oven properly: A hot oven is crucial for achieving crispy Brussels sprouts. Make sure your oven is fully preheated before adding the baking sheet.
- Toss with olive oil and seasonings evenly: Ensure that all the Brussels sprouts are coated with olive oil and seasonings for uniform cooking and flavor.
- Roast at a high temperature: A high temperature (400°F or 200°C) promotes caramelization and crisping.
- Don’t be afraid to experiment with flavors: Try adding different herbs, spices, or nuts to customize the recipe to your liking. A touch of lemon zest can brighten up the flavors.
Testing Notes: In my testing, I found that preheating the baking sheet for a few minutes before adding the Brussels sprouts helps them crisp up even more. I also experimented with different types of vinegar, and balsamic vinegar was the clear winner, providing the perfect balance of sweetness and acidity. Also, roasting the walnuts separately, lightly before adding them to the sprouts, gives them an added crunch and avoids burning.
FAQ: Your Brussels Sprouts Questions Answered
Why are my Brussels sprouts bitter?
Bitterness in Brussels sprouts can be caused by overcooking or using older, larger sprouts. Choose smaller, younger sprouts, and avoid overcooking them. Roasting them at a high temperature can also help reduce bitterness.
Can I make this recipe ahead of time?
Yes, you can roast the Brussels sprouts and pancetta ahead of time and then reheat them before serving. However, the walnuts are best added fresh for maximum crunch. Store the roasted sprouts and pancetta separately in the refrigerator for up to 2 days.
How do I store leftover Brussels sprouts?
Store leftover Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven or microwave before serving.
Can I freeze Brussels sprouts with walnuts and pancetta?
Freezing is not recommended as the texture of the Brussels sprouts may become mushy. The walnuts may also lose their crispness.
What other vegetables can I add to this dish?
You can add other root vegetables like sweet potatoes, carrots, or butternut squash. These will roast nicely alongside the Brussels sprouts and complement the other flavors.
Can I make this recipe vegetarian?
Yes, simply omit the pancetta. To add a smoky flavor, use smoked paprika or a dash of liquid smoke.
