Ingredients
  

  • 2 ½ pounds Brussels sprouts , trimmed and cut in half through the stem
  • 1 small onion , minced
  • 4 garlic , minced
  • 2 teaspoons fresh thyme , minced
  • 1 tablespoon all-purpose flour
  • 1 tablespoon extra virgin olive oil , divided
  • 3 tablespoon unsalted butter , melted or extra virgin olive oil
  • 1-½ cups heavy cream , at room temperature
  • ¾ cup water
  • 1 cup Panko Bread Crumbs
  • ½ cup finely grated grana padano , shredded, divided
  • ½ cup parmesan cheese , grated
  • 2 teaspoons knorr chicken flavored bouillon , adjust to taste
  • ¾ teaspoon kosher salt , divided
  • ¼ teaspoon ground black pepper
  • ¼ teaspoon cayenne pepper
  • ¼ teaspoon freshly grated Nutmeg

Instructions
 

Prepare Brussels Sprouts:

  • Adjust the oven rack to the middle position and heat to 450°F. Grease a 9x13-inch broiler-safe baking dish.
  • Toss Brussels sprouts with oil, ½ teaspoon kosher salt, and ¼ teaspoon ground black pepper in the baking dish. Bake until well browned and tender, about 30-35 minutes. Then, cool on a wire rack for 5 or up to 30 minutes.

Prepare Panko Topping:

  • In a medium saucepan, melt 1 tablespoon butter over medium heat. Add panko, cooking until golden, around 3 minutes. Transfer to a bowl and mix in ¼ teaspoon each of kosher salt and black pepper. Set aside.

Make Cream Sauce:

  • In the same saucepan, melt 2 tablespoons butter. Add onion and garlic, cooking until softened, about 5 minutes. Stir in flour and cook for 1 minute. Whisk in cream, water, and chicken-flavored bouillon. Bring to a boil, then remove from heat. Whisk in ¼ cup Grana Padano, Parmesan, nutmeg, cayenne, and ¼ teaspoon black pepper until smooth. Taste and adjust seasoning with salt if needed.

Assemble & Bake:

  • Pour cream mixture over Brussels sprouts in the dish, stirring to combine. Sprinkle evenly with panko mixture and remaining ¼ cup Grana Padano. Bake until bubbling and golden brown on top, 5-10 minutes. Let cool on a wire rack for about 10 minutes before serving.

Notes

How to Store & Re-Heat:
Store in an airtight container in the refrigerator for up to 2 days. Reheat in the oven uncovered at 350°F for 10-15 minutes or use the microwave with 30-second intervals until heated through.
Make Ahead & Freeze:
Prepare a day ahead and reheat in a preheated oven at 350°F (175°C) until warm and crispy on top. We do not recommend freezing Brussels Sprouts Gratin, as it can affect the texture.
