Instructions

Preheat your oven to 375°F (190°C) and prepare the Brussels sprouts by washing, trimming, and halving them.
Melt unsalted butter in a skillet over medium heat, then sauté diced onion until translucent. Stir in garlic and red pepper flakes and sauté for an additional 1-2 minutes.
Add flour to the skillet and stir to combine, cooking for 1-2 minutes until lightly golden.
Gradually whisk in chicken broth and heavy cream, cooking until slightly thickened, about 3-5 minutes. Season with salt and pepper.
Remove from heat and mix in gruyère and parmesan until melted and creamy.
Gently fold the halved Brussels sprouts into the cheese sauce until fully coated.
Pour the mixture into a greased 9×13 inch baking dish and top with crispy fried onions.
Bake for 30-35 minutes until golden brown and bubbly.

Notes

For added flavor, consider mixing in cooked bacon or pancetta with the cheese sauce.
Allow the casserole to rest for 5-10 minutes before serving for easier serving.
You can prepare the casserole ahead, refrigerate, and bake just before serving.
