If your go-to pasta order is fettuccini alfredo, youll quickly fall in love with this creamy, cheesy chicken spaghetti casserole. The nutty, salty asiago cheese makes for a rich and decadent sauce, but a squeeze of lemon juice and a handful of fresh herbs keep the flavors balanced. Because it finishes under the broiler, the dish is easy enough for even the busiest of weeknights. Serve with garlic bread or a simple side salad, and a glass of crisp white wine for the adults. If you want to try a different protein, opt for cooked shrimp or crab instead of rotisserie chicken.
