How to Make Au Gratin Brussels Sprouts

  1. Wash and trim 1 pound of Brussels sprouts. Halve or quarter larger sprouts.
  2. Bring a large pot of salted water to a boil. Add the Brussels sprouts and cook until tender-crisp, about 5-7 minutes. Drain well.
  3. Preheat oven to 375°F (190°C).
  4. Melt 4 tablespoons of butter in a medium saucepan over medium heat.
  5. Whisk in 4 tablespoons of all-purpose flour and 1/2 teaspoon of salt. Cook for 1-2 minutes, stirring constantly, until a smooth paste forms (roux).
  6. Gradually whisk in 1 1/2 cups of milk and 1/2 cup of sour cream. Continue whisking until smooth.
  7. Bring to a simmer, stirring frequently, until the sauce has thickened slightly, about 2-3 minutes. Do not boil.
  8. Remove from heat and stir in 1 cup of grated Parmesan cheese.
  9. Pour the cheese sauce over the cooked Brussels sprouts in a shallow baking dish.
  10. Sprinkle 1/2 cup of shredded cheddar cheese over the top.
  11. Bake for 15-20 minutes, or until the cheese is melted, bubbly, and lightly browned.
