Why This Recipe Works
The secret to this dish’s success lies in roasting the Brussels sprouts to golden perfection before smothering them in the Alfredo sauce. The crispy edges of the sprouts add a wonderful contrast to the silky, cheesy sauce. It’s a side dish that feels luxurious yet easy to make!
Your Grocery List
- 1 lb Brussels sprouts, trimmed and halved
- 2 tablespoons olive oil
- Salt and pepper, to taste
- 2 tablespoons butter
- 2 cloves garlic, minced
- 1 cup heavy cream
- 3/4 cup grated Parmesan cheese
- 1/4 teaspoon nutmeg (optional)
- Fresh parsley, for garnish (optional)
Techniques and Tips for Perfect Brussels Sprouts
For the best results, follow these tips to ensure your sprouts and sauce turn out perfectly:
- Roast at High Heat: Preheat your oven to 400°F and spread the Brussels sprouts in a single layer to ensure even caramelization.
- Don’t Overcrowd: Give the sprouts space on the baking sheet to prevent steaming instead of roasting.
- Whisk the Sauce: Stir the Alfredo sauce continuously to prevent it from separating, and use freshly grated Parmesan for a smoother texture.
Storing and Reheating Leftovers
This dish is so good you might not have leftovers, but if you do, here’s how to handle them:
- Storage: Store leftover Brussels sprouts in Alfredo sauce in an airtight container in the fridge for up to 3 days.
- Reheating: Reheat gently on the stovetop over low heat, adding a splash of milk or cream to loosen the sauce if needed. Avoid microwaving, as it can cause the sauce to separate.
- Next-Day Twist: Toss leftovers with pasta or serve over rice for a quick and easy meal!
