Ingredients
  

  • 1 lb Brussels sprouts trimmed of outer leaves and sliced in half
  • pink salt to taste
  • Freshly cracked black pepper to taste
  • Olive oil spray
  • 1 tbsp butter
  • 5 cloves garlic minced
  • 1 cup heavy cream
  • 2 ounces cream cheese cubed
  • 1 tsp fresh thyme leave chopped (or 1 tbsp dried, crushed)
  • 1 cup freshly grated Parmesan cheese
  • 5 ounces Gruyère cheese about 1 1/3 cups, shredded and divided (can sub Swiss or white cheddar)
  • 1/2 cup keto breadcrumbs (can substitute ground pork rinds) *See Notes

Instructions
 

  • Preheat oven to 400 degrees F.
  • Butter a cast iron skillet or a small casserole dish.
  • Add the Brussels sprouts and season with salt and pepper. Spray olive oil over the Brussels sprouts and place in the lower third of the oven.
  • Bake for 15 minutes, toss and bake an additional 10 minutes.
  • Meanwhile, heat a medium skillet over medium heat. Add butter and let it melt, add the garlic and cook until fragrant, about 1 to 2 minutes.
  • Add the heavy cream and cream cheese and whisk until the cream cheese is incorporated into the heavy cream.
  • Cook over medium-low heat for about 4 minutes, stirring, until the sauce thickens.
  • Add the thyme, salt, pepper, parmesan cheese, and 1 cup of shredded cheese and stir until the cheese is melted and incorporated into the sauce.
  • Pour over the Brussels sprouts, and top with the remaining shredded cheese and breadcrumbs.
  • Bake for 15 minutes until the top is lightly browned and bubbly.

Notes

To make keto breadcrumbs cut the crust off of 2 to 3 slices of keto bread and toast until medium-dark. You want it dry but not burnt.
When the toast cools tear it into pieces and pulse in a food processor until you have panko-like breadcrumbs.
