What ingredients go into this recipe
A few basic ingredients are used to make brussels sprouts gratin starting with fresh brussels sprouts (or as some say brussel sprouts). Next is the au gratin sauce which is made of milk, shaved or shredded parmesan cheese, cream cheese, butter, chicken bullion powder (this is the secret making it soooo good!), garlic powder, red wine vinegar, salt and pepper to taste and fresh parsley for garnish.
How to make this recipe
STEP 1: Soak the brussels sprouts first in lightly salted water for 10-20 minutes. Cut the base or the stem ends of the brussels sprouts, pulling off any yellow outer leaves. Slice each one in half and spread them in a 9-inch baking dish.
STEP 2: In a medium saucepan heat the butter, milk, and cream cheese on medium heat until the cheese melts. Then stir in the flour, chicken bullion, garlic powder, vinegar, and quickly mix it to thicken. After the cheese sauce is ready pour it over the brussels sprouts.
STEP 3: The sauce is thick so you may need to use the back of a spoon to spread it out evenly.
STEP 4: After the cheese sauce is on, sprinkle parmesan cheese evenly on top.
STEP 5: Cover the brussels sprouts gratin with foil and bake for 25 minutes, and remove the foil and bake uncovered for 5 more minutes. Sprinkle with salt and pepper to taste and fresh parsley and serve right away!
