  • 1.5 lbs brussel sprouts
  • 2 tbsp extra virgin olive oil
  • 1/2 tsp freshly cracked black pepper
  • 1 tsp kosher salt

For the Sauce:

  • 2 tbsp salted butter
  • 1.5 tbsp gluten-free flour I use Bob's Red Mill 1 to 1 baking flour. You can sub regular, all-purpose flour here.
  • 1/4 cup dry white wine
  • 1/2 cup heavy cream
  • 3/4 cup chicken broth

Instructions

  • Preheat oven to 400℉ and center rack in the center of the oven.

Why does my stomach hurt so bad after eating brussel sprouts? ›

Why do my Brussels sprouts taste weird? ›

How do you get the bitterness out of Brussels sprouts? ›
