How to Make Garlicky Creamy Brussels Sprouts Au Gratin
Step 1: Preheat the Oven
Position a rack in the center of your oven and preheat it to 375ºF. Preheating ensures that your Brussels sprouts bake evenly and helps achieve that perfect bubbly cheese topping.
Step 2: Prepare the Ingredients
While the oven heats up, clean and trim those lovely brussels sprouts. Then, shred your fontina, cheddar, and parmesan cheese. Combining them beforehand makes it easy to incorporate into the sauce later.
Step 3: Infuse the Butter with Garlic
In an oven-proof pan (like a cast iron skillet), melt the butter over medium heat with minced garlic. Allowing the garlic to infuse into the butter creates a beautiful flavor base for your creamy sauce. Just be careful not to let it brown; we want soft garlic rather than crispy bits!
Once fragrant, turn off the heat and stir in your heavy cream along with salt, pepper, garlic powder, and nutmeg. Mixing in half of your combined shredded cheeses at this stage adds richness to your sauce.
Step 4: Combine Everything
Add those halved brussels sprouts into your creamy mixture. Stir well so each sprout gets coated in that luscious sauce! Spread them out in an even layer for consistent cooking. Finally, sprinkle the remaining cheese over top – because we all know more cheese is always better!
Step 5: Bake Until Perfectly Melty
Pop your pan into the preheated oven for about 18-25 minutes. Keep an eye on them until you see that glorious cheese melting and bubbling away! Once they look golden brown and delicious, take them out and serve warm alongside your favorite main dishes.
And there you have it—a delightful dish of Garlicky Creamy Brussels Sprouts Au Gratin that’s sure to impress! Enjoy every bite!
Pro Tips for Making Garlicky Creamy Brussels Sprouts Au Gratin
Making the perfect Garlicky Creamy Brussels Sprouts Au Gratin is all about those little details that elevate the dish. Here are some pro tips to ensure your dish turns out absolutely delightful!
- Use fresh Brussels sprouts: Fresh Brussels sprouts provide a crisp texture and vibrant flavor that frozen varieties simply can’t match. Look for bright green sprouts that feel firm to the touch.
- Don’t rush the garlic: Gently infusing the butter with garlic allows its flavors to deepen without burning. Burnt garlic can taste bitter, so keep an eye on it while it simmers.
- Mix cheeses for depth: Combining different types of cheese, like sharp cheddar and creamy fontina, adds layers of flavor that make your au gratin irresistible. Feel free to experiment with your favorite cheese blends!
- Bake until bubbly: For a perfectly melted and golden cheese topping, bake until you see the cheese bubbling and lightly browning. This not only enhances the flavor but also adds a lovely visual appeal.
- Let it rest before serving: Allowing the dish to rest for a few minutes after baking will help it set up nicely, making it easier to serve and enhancing the overall flavor.
