Step‑by‑Step Instructions for Garlicky Creamy Brussels Sprouts
Step 1: Preheat the Oven
Begin by preheating your oven to broil, allowing it to reach a high temperature of around 500°F (260°C). This will ensure that your Garlicky Creamy Brussels Sprouts Au Gratin gets that perfect golden crust on top. While it warms up, gather your ingredients and prepare your cast iron skillet for the next steps.
Step 2: Sauté the Garlic
In your preheated skillet, melt a generous tablespoon of butter over medium heat. Add minced garlic and sauté for about 1-2 minutes until fragrant and lightly golden, stirring regularly to prevent burning. You want the kitchen to fill with the heavenly aroma of garlic, indicating it’s time to move on to the Brussels sprouts.
Step 3: Prepare the Brussels Sprouts
Next, add trimmed and halved Brussels sprouts to the skillet, stirring them into the fragrant garlic-butter mixture. Cook for about 5 minutes, tossing occasionally, until the sprouts begin to soften and take on a touch of color. This step enhances their flavor, ensuring a delightful bite in your finished dish.
Step 4: Incorporate the Cream
Pour in a cup of heavy cream, adjusting the amount for desired richness, and stir to combine thoroughly with the Brussels sprouts. Allow the mixture to simmer for about 2-3 minutes over medium heat, allowing the cream to warm and blend with the garlic and sprouts. You will notice a rich, creamy sauce forming, ready for the cheese.
Step 5: Add the Cheeses
Sprinkle a mix of white cheddar, fontina, and parmesan cheeses evenly over the creamy Brussels sprouts, ensuring an even distribution. Allow the cheese to melt into the mixture over medium heat for an additional 2-3 minutes, stirring gently. You’ll see the cheese start to blend beautifully into the creamy sauce, creating a luscious base.
Step 6: Broil to Perfection
Carefully transfer the skillet to your preheated broiler, positioning it on the top rack. Broil for about 5-7 minutes, keeping a close watch until the cheese is bubbly and golden brown. The bubbling action and rich color indicate that your Garlicky Creamy Brussels Sprouts Au Gratin is nearly ready to be served.
Step 7: Serve and Garnish
Once broiled to perfection, remove the skillet from the oven, taking care to protect your hands. Let it sit for a minute before serving hot. If desired, garnish with fresh parsley for a pop of color and added freshness. Your delicious Garlicky Creamy Brussels Sprouts Au Gratin is a stunning centerpiece for your holiday table!

Expert Tips for Garlicky Creamy Brussels Sprouts
-
Choose Fresh Brussels: Use fresh, bright green Brussels sprouts for the best flavor. Avoid any that are yellowed or wilted.
-
Butter vs. Oil: While butter adds richness, olive oil can be a lighter alternative and suitable for a dairy-free dish.
-
Adjust Garlic Levels: Sauté garlic until just golden—overcooking leads to bitterness. Adjust the amount based on your family’s flavor preference.
-
Broil Carefully: Keep a close eye while under the broiler. Cheese can burn quickly; you want it to be bubbly and golden without becoming charred.
-

Garlicky Creamy Brussels Sprouts Au Gratin Recipe FAQs
How do I select the best Brussels sprouts?
When choosing Brussels sprouts, look for fresh, bright green sprouts that are firm to the touch. Avoid any that have yellowed leaves or dark spots all over, which indicate overripeness. The smaller the Brussels sprout, the sweeter they tend to be, so aim for medium-sized ones for the best flavor in your dish.
What’s the best way to store leftovers?
Store any leftover Garlicky Creamy Brussels Sprouts Au Gratin in an airtight container in the refrigerator for up to 3 days. This method helps preserve their creamy texture and flavors. When you’re ready to reheat, place them in a preheated oven at 350°F (175°C) for about 15-20 minutes to enjoy them as if freshly made!
Can I freeze Garlicky Creamy Brussels Sprouts Au Gratin?
Absolutely! To freeze your Brussels sprouts au gratin, allow the dish to cool completely, then transfer it to an airtight freezer-safe container. It can be frozen for up to 2 months. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight and reheat in the oven until warmed through. Just keep in mind that the cheese topping may be less crispy after freezing.
What if my cheese doesn’t melt properly?
If you find that your cheese isn’t melting as you’d like, check the heat setting on your stovetop. It’s important to cook over medium heat before broiling to ensure the cheese melts thoroughly. Don’t be shy to give it a good stir when adding the cheese, so it mixes well with the creamy sauce. Also, keep a close eye while broiling; it can burn quickly, but you want it to be bubbly and golden.
Are there any dietary considerations for pets or allergies?
Yes, if you have pets at home, it’s important to note that garlic can be toxic to dogs and cats, so it is best to keep this dish away from them. Additionally, while this recipe is gluten-free, be sure to double-check your cheese brands to confirm they are gluten-free if that’s a concern. For those with dairy allergies, consider using dairy-free cream and cheese alternatives to enjoy a similar flavor without the allergens.
Can I make this dish ahead of time?
Absolutely! You can prep your Garlicky Creamy Brussels Sprouts Au Gratin up to the point of adding the cheese. Simply follow all the steps until that point, cover it, and refrigerate.
