Step‑by‑Step Instructions for Garlicky Creamy Brussels Sprouts Au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C); this ensures the perfect baking temperature for your Garlicky Creamy Brussels Sprouts Au Gratin. While the oven heats, gather your ingredients and prepare your cooking area. Setting the oven first saves time by allowing it to reach the ideal temperature as you prepare the dish.
Step 2: Prepare Brussels Sprouts
Trim the ends off the Brussels sprouts and carefully slice each one in half. Melt 2 tablespoons of butter in a large skillet over medium heat, then add the halved sprouts. Sauté for about 5–7 minutes until they are lightly browned and tender, tossing occasionally to achieve even cooking and a lovely golden color on the outer leaves.
Step 3: Make the Garlic Cream Sauce
Add 3 minced garlic cloves to the skillet with the sautéed Brussels sprouts, stirring for about 1 minute until fragrant. Next, pour in 1 cup of heavy cream and season with salt, pepper, and a pinch of nutmeg. Stir the mixture gently while it heats, allowing the flavors to mingle for approximately 2–3 minutes until it begins to simmer.
Step 4: Incorporate Cheeses
Reduce the heat to low and sprinkle in 1 cup of grated white cheddar cheese, 1/2 cup of grated parmesan, and 1 cup of fontina cheese. Stir continuously until the cheeses melt into a velvety sauce, about 3–4 minutes. Ensure everything is well combined and creamy before moving to the next step; this creates the indulgent sauce that will coat the Brussels sprouts beautifully.
Step 5: Bake
Transfer the mixture to a greased casserole dish, spreading it evenly. If desired, sprinkle additional cheese on top for an enhanced crust. Bake in the preheated oven for 20 minutes, or until the top is golden brown and bubbly. Keep an eye on it during the last few minutes to achieve that perfect crispiness without burning.
Step 6: Serve
Once the Garlicky Creamy Brussels Sprouts Au Gratin is out of the oven, let it sit for about 5 minutes to allow the sauce to set. Optionally, garnish with freshly chopped parsley for a touch of color before serving. This creamy delight, with its crispy topping, is now ready to be the star of your festive feast!

Garlicky Creamy Brussels Sprouts Au Gratin Recipe FAQs
How do I select the best Brussels sprouts?
Absolutely! Look for Brussels sprouts that are bright green and firm to the touch. Avoid any that have dark spots or are soft, as these can indicate overripeness. If you’re opting for frozen, ensure that they are well-packaged without any ice crystals.

What should I do if my cheese clumps while melting?
If you find your cheese clumping, don’t panic! This often happens if the cheese is added to a sauce that’s not hot enough. To remedy this, keep the cream sauce on medium-low heat and add cheese gradually, stirring continuously until it’s melted and smooth. This will ensure a beautifully creamy sauce!
Are there any dietary considerations for this recipe?
Very much so! This Garlicky Creamy Brussels Sprouts Au Gratin can be adjusted to suit various dietary needs. To keep it gluten-free, make sure any packaged ingredients are labeled gluten-free.
