Cheesy Chicken Spaghetti Squash Recipe

While spaghetti squash isn't quite as neutral-tasting as noodles, it too tends to take on the flavor of the sauce and cheese it's topped with. As developer Erin Johnson says of this cheesy chicken spaghetti squash recipe, "I like making this dish when I want the flavors of chicken spaghetti, but don't want the pasta." To make this winter squash look a little more noodle-like, Johnson likes to cut the squash into rings before baking it. This spaghetti squash slicing secret, she explains, "creates longer strands, making the overall appearance more reminiscent of pasta."

This particular chicken spaghetti (squash) dish is not Italian-style, since Johnson opts to use a cream-style sauce made from condensed soup. She kicks up the flavor with the addition of sliced jalapeños and also tells us, "I like to top this with salsa and sour cream and serve it with a side salad."

What Tweaks Can I Make To This Cheesy Chicken Spaghetti Squash Recipe?

While some recipes can't stand for too much alteration, this isn't one of them. As Johnson tells us, "This recipe is very substitution-friendly." One substitution you may need to make involves the soup. If you can't find cream of chicken and mushroom, Johnson says, "You can also use just cream of chicken condensed soup." Cream of mushroom soup would work, as well.

Johnson also suggests switching up the bell pepper colors and adding (or subtracting) jalapeños to alter the spice level, while she notes that you can always add some other vegetables if you wish. The cheese, too, can be swapped -- Johnson says, "I like to use Colby Jack cheese, but cheddar or pepper Jack are also great substitutions." If you'd like to replace the boneless, skinless chicken breasts with thighs, these will probably cook at the same rate because the meat is cut into pieces, but a handy thermometer will let you know for sure.

Does Cheesy Chicken Spaghetti Squash Make Good Leftovers?

This cheesy chicken spaghetti squash casserole is a fairly sizable one as it makes six servings, but there's no need to worry if you can't finish it all up in a single day. Johnson says that any leftovers should be good for up to 3 days in the refrigerator, while they can also be frozen if you need to keep them for a longer period of time. If you freeze individual portions in microwave-safe containers, you can have a meal in minutes the next time you want some cheesy chicken goodness.

If you're into meal prepping, Johnson says the casserole works for that, as well. "I like to prep all the ingredients and then mix [them] together immediately before baking," she says, but also notes that the casserole, once assembled, can be refrigerated for a day before being cooked. You could also pre-assemble that same casserole and freeze it, as well, then thaw it overnight in the refrigerator before baking it as per the recipe directions.
