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 temperature is essential for achieving that perfect bubbly and golden crust on your Garlicky Creamy Brussels Sprouts Au Gratin. While the oven heats, gather your ingredients and equipment, including a large skillet and a casserole dish to prepare for the next steps.
Step 2: Sauté the Garlic
In a large skillet, melt 2 tablespoons of butter over medium heat. When the butter starts to foam, add 3 minced garlic cloves and sauté for about 1 minute until fragrant. Be careful not to let the garlic brown too much, as it can become bitter. The goal is to create a fragrant base that will elevate the flavor of your creamy Brussels sprouts.
Step 3: Cook the Brussels Sprouts
Add the trimmed and halved Brussels sprouts to the skillet with the garlic. Cook them for approximately 8-10 minutes, stirring occasionally, until they begin to caramelize around the edges and become tender. You want the sprouts to retain a slight crispness, which will add texture to the final dish.
Step 4: Incorporate the Cream and Spices
Once the Brussels sprouts are perfectly cooked, stir in 1 cup of heavy cream, a pinch of nutmeg, and season with salt and pepper. Bring the mixture to a gentle simmer over medium heat, allowing the cream to thicken slightly while you stir everything together. This savory blend will create a luscious sauce for your creamy Brussels sprouts.
Step 5: Melt in the Cheeses
Remove the skillet from the heat and add ½ cup each of parmesan, cheddar, and fontina cheese, stirring until fully melted and combined. The cheeses will add a wonderful creaminess and flavor to your Garlicky Creamy Brussels Sprouts Au Gratin. Make sure to incorporate the cheese well, so every bite is rich and indulgent.
Step 6: Transfer to a Casserole Dish
Pour the cheesy Brussels sprout mixture into a prepared casserole dish, spreading it evenly. If you’d like, sprinkle additional cheese on top for an extra cheesy crust. This will create a beautiful, golden layer that enhances the appeal of your dish when baked, ensuring a delightful presentation at your dinner table.
Step 7: Bake to Perfection
Place the casserole dish in the preheated oven and bake for 20 minutes. Keep an eye on the dish as it bakes; you’ll know it’s ready when the edges are bubbling, and the top is beautifully golden brown. This final baking step melds the flavors together and gives that satisfying creaminess to your Garlicky Creamy Brussels Sprouts Au Gratin.

Tips for the Best Creamy Brussels Sprouts
-
Don’t Overcook: Sauté Brussels sprouts just until they caramelize; overcooking makes them mushy. A slight crunch adds great texture to your gratin.
-
Quality Cheese Matters: Use high-quality cheeses for the best flavor. Avoid pre-shredded options, as they often contain anti-caking agents that can affect melting.
-
Bake Until Bubbly: Watch for bubbling around the edges while baking; this indicates that your creamy Brussels sprouts are perfectly cooked and ready to be enjoyed.
-
Nutmeg Wisely: A little goes a long way! Too much nutmeg can overwhelm the dish, so start with just a pinch to add warmth without overpowering the other flavors.
-
Make it Your Own: Feel free to experiment with variations like adding thyme or swapping in other cheese blends. Customize the recipe while keeping it deliciously creamy!

Creamy Brussels Sprouts Recipe FAQs
How do I select the best Brussels sprouts?
Absolutely! When choosing Brussels sprouts, look for firm, compact sprouts with bright green coloring. Avoid any that have dark spots or yellowing leaves, as these can indicate overripeness or poor quality. Ideally, they should feel heavy for their size.
What is the best way to store leftover Creamy Brussels Sprouts?
Store your leftover creamy Brussels sprouts in an airtight container in the refrigerator for up to 3 days. When you are ready to enjoy them again, reheat gently in the microwave or oven to retain their luscious creaminess—around 15 minutes at 350°F (175°C) should do the trick!

How can I avoid mushy Brussels sprouts in my dish?
Very! To prevent Brussels sprouts from becoming mushy, sauté them just until they begin to caramelize, typically around 8-10 minutes. This slight crispness is essential, as they will soften further during the baking process. Keep an eye on them, and stir occasionally for even cooking.
