Chicken Spaghetti Recipe Notes
Making this chicken spaghetti recipe casserole is an easy way to put the sparkle back in dinner. People often assume that chicken spaghetti is made with a tomato-based sauce but that doesn’t have to be the case. Sit back and read on to see how to create the most amazing dreamy creamy chicken spaghetti casserole recipe that will satisfy the heartiest appetites.
Success depends on techniques, even simple ones. For instance, be sure to remove your roux from the heat when you add your milk/beer base to thicken up the sauce. Leaving it on the heat too long can scorch the flour and completely change the flavor of your sauce.
Speaking of which, you’ll want to sauce your spaghetti pasta while it’s hot. The heat helps the sauce evenly coat and stick to the warm starchy pasta for a superior restaurant-style flavor.
Chicken Spaghetti Ingredients Notes
The right ingredients are vital to the intense robust flavor of this recipe. Here’s what you need to know about the stuff in this incredible dish!
Spaghetti pasta – Be sure to salt your pasta water. I like to use 1-2 tablespoons per gallon of water. The spaghetti pasta will absorb the salted pasta water as it cooks, essentially flavoring the pasta from the inside out.
Veggies – You must sauté your veggies, preferably in butter. Sautéing veggies before adding them to recipes helps coax out their sweeter more mellow flavors and combats bitterness. Besides, it’s the first step in the recipe.
Roux – Taking the time to heat your spices and flour for just a minute or two before moving to the next step makes you look like a Rockstar in the kitchen.
First, it perks up your spices for an aromatic complexity you won’t believe. Second, it gets rid of that ‘flour’ flavor so your sauce tastes like you want it to.
Cheese – So here’s the thing. There is something to be said for the convenience of pre-shredded cheese. It just works!
But, if you want a super creamy sauce for this spaghetti casserole, then consider shredding cheese off a block. Pre-shredded cheeses typically have anticoagulants and stabilizers added to them which does affect their melting characteristics.
Cheesy Chicken Spaghetti Storing Tips
Storing this is super simple. Once those hungry tummies are satisfied and everyone is feeling all warm and fuzzy, you can take an inventory of your cheesy chicken spaghetti casserole recipe. If there are leftovers, they’ll need to go into the fridge in an airtight container.
Can You Freeze This?
So, here’s the thing. Cheese sauce can sometimes be as finicky as pasta in arctic temperatures. If you must freeze, it’s best to only freeze the homemade sauce and make fresh pasta when you’re ready to throw it in the oven.
Cheese sauce expands in the freezer, so leave room for expansion in the freezer-safe bag/container. It freezes best in the colder temperatures of a deep freezer and you’ll need to mix it well upon thawing. If there is separation, it may help to add just a little cream to retrieve that creamy texture again.
Chicken Spaghetti Bake Make Ahead Tips
Making a chicken spaghetti bake ahead casserole can totally simplify a crazy busy schedule. There isn’t a lot of work involved in getting this chicken spaghetti casserole recipe into the oven, so it only takes a few minutes. Using rotisserie chicken and pre-shredded cheese adds flavor and makes things even simpler.
How Long Can You Keep This In The Fridge?
This recipe will stay fresh and yummy in the fridge for up to 4 days, if nobody knows its in there. Once people find it though, it tends to get gobbled up!
