An easy weeknight meal

What to serve with this Creamy Chicken Spaghetti
Baked chicken spaghetti is rich and super filling, so it doesn’t need heavy side dishes. You with bread sticks or garlic bread, and a cucumber salad or fresh green salad dressed with vinaigrette.
Can you freeze Creamy Chicken Spaghetti?
Chicken spaghetti freezes exceptionally well, so go ahead and make it in advance. Once you place it in the casserole dish, you don’t need to bake it first, just freeze for up to four month.
Line your dish with parchment paper and let it freeze solid, then transfer to a large freezer bag. That way you don’t have to tie up your casserole dish for months. The chicken spaghetti is already pre-formed for the dish, so all you have to do is slide it back in when you’re ready to reheat.
You can cook this directly from frozen (but be careful, most glass dishes cannot go from freezer to oven). Cover it in foil to prevent the cheese topping from overcooking. Cook at 350°F for about an hour, or until it is piping hot throughout!
Top Tips
- You can use wholewheat pasta. Just make sure you allow a bit extra time for the cook, to make sure the pasta is done.
- You can pretty much use any vegetable you want. You’ll want to add harder vegetables (think root vegetables like carrots and parsnips) earlier on with the onions and bell peppers.
- To add extra spice – use a spicy cheese blend like habanero cheddar.
- If the casserole is browning too quickly – cover the casserole with tented aluminium foil.
