Dear Reader, I’m so excited to share this Baked Mushroom Fettuccine Alfredo, a riff on the TikTok baked feta pasta. This idea was suggested to me by a Dear Reader Allison P. after I posted my upgrade to the original Uunifetapasta by Jenni Häyrinen. This makes the creamiest, dreamiest mushroom fettuccine Alfredo sauce with very little effort! This is a pushy recipe Dear Reader!
