Ingredients

Scale

Brussels Sprouts

  • 1 1/2 lbs Brussels sprouts

Cheese Sauce

  • 1/4 cup butter
  • 1/4 cup flour
  • 2 cups 2% milk
  • 4 oz Frigo® Crumbled Blue Cheese

Topping

  • 1/4 cup sliced almonds

Instructions

  1. Preheat and Prepare Brussels Sprouts: Preheat your oven to 350°F (175°C). Bring a large pot of salted water to a boil. Cook the Brussels sprouts in the boiling water for 3 minutes until just tender. Drain the sprouts well and transfer them to a greased baking dish.
  2. Make the Roux and Sauce: In a saucepan, melt the butter over medium-low heat. Stir in the flour and whisk continuously until smooth, cooking for about 3 minutes to eliminate the raw flour taste. Gradually whisk in the 2% milk and increase the heat to medium. Continue whisking until the sauce thickens to a creamy consistency. Remove the sauce from heat.
  3. Add Cheese and Season: Crumble the blue cheese into the warm sauce and stir gently until the cheese melts completely into the sauce. Season the sauce to taste with salt (use sparingly) and freshly ground black pepper.
  4. Combine and Top: Pour the cheesy blue cheese sauce evenly over the prepared Brussels sprouts in the baking dish. Sprinkle the top with the sliced almonds for a crunchy finish.
  5. Bake the Gratin: Place the baking dish in the preheated oven and bake for 25 minutes, or until the top is golden brown and bubbly, and the almonds are lightly toasted.

Notes

  • You can prepare the gratin up to Step 3 a day in advance. Cover and refrigerate until ready to bake.
  • For best results, bring the dish to room temperature before baking if refrigerated.
  • Make sure to use salted water when boiling the sprouts to enhance their flavor.
  • Adjust seasoning to taste, but be cautious with salt since blue cheese is naturally salty.
  • For a nuttier flavor, toast the sliced almonds lightly before sprinkling on top.
