In a large pot of salted, boiling water, cook pasta according to package directions.
To make the creamy alfredo sauce, melt butter in a skillet over medium heat. Add garlic, stirring frequently, until fragrant, about 1 minute. Add mushrooms. Whisk in flour about 1 minute more.
Slowly add in chicken broth, thyme and basil. Whisk constantly until well blended, about 2 minutes. Stir in half and half and parmesan until thickened, about 2 minutes. Add more half and half if the sauce is too thick. Season with salt and pepper.
Stir in pasta, ham, bacon and peas. Toss gently until well combined. Garnish with parsley.
In a large bowl, whisk the first 10 ingredients together. Then dip each slice of bread into the egg mixture. Arrange slices in the prepared dish. Pour the remains of the egg mixture on top. Cover and refrigerate overnight.
Remove from fridge 30 minutes prior to baking it. Preheat oven to 350F. In a small bowl combine the first eight topping ingredients. Spread on top of French Toast.
Bake, uncovered, for 40-45 minutes. Let stand 10 minutes before serving. Drizzle with syrup.
