The recipe I am sharing today is a completely Trader Joe's Mac and Cheese Casserole! Their macaroni is a bit larger than traditional elbows, so it perfectly takes in the sauce. The unexpected cheddar is sharp and nutty and adds tons of flavor to the casserole. I topped my dish with bread crumbs mixed with Trader Joe's Mushroom Umami Seasoning for even more kick! This seasoning is a mixture of salt, dried mushrooms, dried onion, mustard seed, red pepper and thyme. Is is a savory, earthy and sort of hot spice.
