Cheesy, rich, and comforting, this Chicken Tetrazzini is a dinner that everyone will love. This baked chicken spaghetti casserole is made from scratch and comes together quickly by using cooked chicken.
We love baked pasta dishes! If you are the same, this Baked Penne is always a hit. My kids devour it! This Cheesy Kielbasa Pasta Casserole is one of my personal favorites.
Sometimes, the only thing that will cut it is comfort food.
And that’s exactly what this Chicken Tetrazzini is.
Chicken, pasta, mushrooms – all in a creamy, cheesy sauce. If this isn’t comfort food, then I don’t know what is!
What is Chicken Tetrazzini?
I actually had to look this one up, because in my head, I was thinking this was an Italian dish.
But I was wrong.
Chicken Tetrazzini was invented in the early 1900s by a chef at the Palace Hotel in San Francisco. He made this dish for opera star Luisa Tetrazzini. Of course, there is another story that says it originated in New York City at the Knickerbocker Hotel. Regardless of its origination, it’s a dish we all love!
Chicken Tetrazzini has spaghetti (or a similar long and skinny pasta) that is coated in a creamy cheese sauce. There are a lot of variations out there. Most of them use a cream of something soup. But this recipe is from scratch! I have no problem with canned cream soup, but I personally just don’t really like them. But really, it takes so little time to make it all from scratch, you won’t even miss the ease of the canned soup.
Ingredients
Scroll down to the recipe card at the end of the post for full amounts and instructions.
- Butter: This is just to cook the mushrooms. You could also use olive oil, or another cooking oil, if desired.
- Mushrooms: Mushrooms are a traditional tetrazzini ingredient, but you do you and leave them out if you aren’t a mushroom fan.
- Garlic: This adds so much flavor! I always like to use freshly minced garlic.
- Salt & Pepper: Both for seasoning.
- Flour: The flour will thicken the sauce slightly. I use all-purpose flour.
- Broth: I use a low-sodium chicken broth. This is the base of your sauce, and adds way more flavor than water, and doesn’t make the sauce overly rich.
- Half and Half: If you don’t have half and half on hand, you can use a mixture of milk and cream. If you use all milk, the sauce won’t be very thick, but if you use all cream, the sauce will be overly rich.
- Cheese: I use a mild or medium cheddar. Feel free to change this up if you want!
- Spaghetti: Again, traditionally chicken tetrazzini is made with spaghetti. But I’m all about breaking the rules to make the recipe works for you, so feel free to change up the pasta.
- Chicken: Using cooked, shredded or cubed chicken will help speed up this recipe. If you don’t have any on hand, you can use a rotisserie chicken.
How to Make Chicken Tetrazzini
STEP 1: Melt the butter in a skillet, I like to use my cast iron skillet, and add the mushrooms. Cook them until they are softened.
STEP 2: Add the garlic, salt, and pepper and cook for another minute.
STEP 3: Sprinkle in the flour and stir it around. It will clump up a little bit, but don’t worry. You just want to make sure the mushrooms get coated.
STEP 4: Stir in the broth and the half and half and stir, stir, stir until it is all blended together. Reduce the heat, and then cook it until the sauce is slightly thickened. It should coat the back of a spoon.
STEP 5: Remove the skillet from the heat, and add in 3 cups of the cheese. Stir this until the cheese is melted.
STEP 6: Add the cooked pasta and the chicken and stir it all together. It’s really thick and cheesy at this point, but stir as well as you can. I find that it is easiest with tongs.
STEP 7: Pour the mixture into a greased baking dish.
STEP 8: Sprinkle the remaining cheese on top, then cover the dish with foil. Bake for 10 minutes, then remove the foil and cook for another 10-15 minutes.
Tips and Tricks
This is best when it is piping hot, so be ready to serve it when it’s hot. When it comes to room temperature, the sauce tends to not stay as creamy.
That being said, leftovers are great once heated up! They heat up well in the microwave. If heating in the oven, you might want to drizzle a little bit of chicken broth in.
This recipe is easy to half if you don’t want as much or if you are feeding less people.
