Ingredients

You only need a handful of high-quality ingredients to make this magic happen:

The Veggies

• Brussels Sprouts – 1.5 lbs, fresh. Trim the woody ends and cut them in half vertically.
• Olive Oil – 2 tablespoons, for the initial roast.
• Salt and Black Pepper – To taste.
• Garlic Powder – 1/2 teaspoon (optional, for extra kick).

The Creamy Sauce

• Boursin Cheese – 1 wheel (5.2 oz), Garlic & Fine Herbs flavor. This is the star ingredient.
• Heavy Cream – 1/2 cup. This helps thin the cheese into a pourable sauce.
• Parmesan Cheese – 1/3 cup, grated. Adds a nutty, salty finish and helps brown the top.
• Mozzarella Cheese – 1/2 cup, shredded (optional, for extra cheese pull).
• Red Pepper Flakes – A pinch, for a subtle heat contrast.

Instructions

Follow these steps to ensure perfectly cooked sprouts and a sauce that doesn’t break.

Step 1: Prep and Roast the Sprouts

1. Preheat your oven to 400°F (200°C). Grease a 9×13 inch baking dish or a medium casserole dish.
2. Place the trimmed and halved Brussels sprouts directly into the baking dish (or on a sheet pan if you prefer).
3. Drizzle with olive oil and season with salt, pepper, and garlic powder. Toss well to coat.
4. Arrange the sprouts cut-side down. This helps them caramelize and get that delicious golden-brown color.
5. Roast for 20–25 minutes until they are tender-crisp and browned.

Step 2: Make the Cream Sauce

1. While the sprouts are roasting, place the Boursin cheese and heavy cream in a small microwave-safe bowl.
2. Microwave in 30-second intervals, stirring in between, until the mixture is smooth and combined. Alternatively, you can do this in a small saucepan over low heat.
3. Stir in half of the parmesan cheese.

Step 3: Combine and Bake

1. Remove the sprouts from the oven. If you roasted them on a sheet pan, transfer them to your baking dish now.
2. Pour the creamy Boursin sauce evenly over the roasted sprouts. Give it a gentle toss if you want them fully coated, or leave it poured over top for a layered look.
3. Sprinkle the remaining parmesan (and mozzarella if using) over the top.
4. Return the dish to the oven and bake for another 10–15 minutes. The sauce should be bubbling, and the cheese on top should be melted and golden.

Step 4: Serve

1. Let the dish sit for 5 minutes before serving to allow the sauce to thicken slightly.
2. Garnish with extra black pepper or red pepper flakes if desired.

Tips for the Best Boursin Sprouts

Want to ensure perfection? Keep these tips in mind:

Don’t Skip the Pre-Roast

Some recipes suggest boiling sprouts, but roasting concentrates their flavor and adds sweetness. Cooking them in the sauce from raw can lead to a watery dish, so stick to the roasting method.

Size Matters

Try to choose Brussels sprouts that are similar in size so they cook evenly. If you have some giant ones, quarter them instead of halving them.

Customize the Cheese

While Garlic & Fine Herbs Boursin is the classic choice, try the Shallot & Chive or Cracked Black Pepper varieties for a different twist.

Variations to Try

Make this dish your own with these delicious additions:

• Add Bacon: Crumble crispy cooked bacon over the top before serving for a salty, smoky crunch.
• Add Nuts: Toasted pecans or walnuts added in the last 5 minutes of baking provide a wonderful textural contrast.
• Lemon Zest: Grate fresh lemon zest over the finished dish to cut through the richness of the cream.
• Caramelized Onions: Mix in some caramelized onions with the sauce for deep, savory sweetness.

Serving Suggestions

These sprouts are versatile enough to pair with almost anything:

• Steak Dinner: The richness pairs perfectly with a grilled ribeye or filet mignon.
• Roast Chicken: Serve alongside a classic herb-roasted chicken and mashed potatoes.
• Holiday Table: It is the perfect companion to roast turkey or glazed ham.

Frequently Asked Questions

Can I make this ahead of time?

Yes! You can roast the sprouts and make the sauce a day in advance. Store them separately in the fridge. When ready to serve, combine them in the dish and bake at 350°F until hot and bubbly (you may need to add a few minutes to the baking time).

Is this recipe keto-friendly?

Yes, Brussels sprouts are relatively low in carbs, and the high-fat cheese and cream make this an excellent option for keto or low-carb diets.

Can I use frozen Brussels sprouts?

Fresh is best for texture. Frozen sprouts tend to release a lot of water and become mushy, which can water down your beautiful cheese sauce. If you must use frozen, thaw and pat them very dry before roasting.
