This is not your average broccoli and cheddar gratin, it is a hyped up version that is more gourmet. It's made with Gruyere cheese, broccoli, scallions all topped with toasted panko breadcrumbs, for a delicious crunch.
3 T.olive oil
6 c. broccoli florets from a small head of broccoli
kosher salt, to taste
3 garlic cloves, minced
1 c. heavy cream
1/2 t. freshly grated nutmeg
1 c. grated Gruyere cheese
1/4 c. thinly sliced scallions, white and green parts
1/2 c. panko breadcrumbs, toasted
Place a large skillet over medium-high heat; add olive oil and then the broccoli and a pinch of salt. Cook, stirring occasionally, for 1 minute. Add garlic; cook until garlic becomes fragrant, about 1 minute.
Reduce heat to medium, add cream and nutmeg, and cook until the cream reduces slightly and the broccoli is cooked through, about 2 minutes. Add the Gruyere and cook, stirring constantly until the cheese is melted, about 1 minute.
Remove from the heat, stir in the scallions, top with the toasted panko breadcrumbs, and serve.
