Camila's Tips
Choose smaller Brussels sprouts, no larger than a golf ball in size, as they tend to be sweeter, more tender, and less bitter than larger ones. This makes them a better choice for cooking in dishes like Brussels Sprouts Gratin.

- 2 teaspoons knorr chicken flavored bouillon , adjust to taste
- ¾ teaspoon kosher salt , divided

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.
