Chicken With Spaghetti Squash

This chicken with spaghetti squash recipe is delicious, elegant, and so easy to make!

In this recipe, we quickly steam the squash in the microwave. Meanwhile, we pan-sear the chicken breasts and make the garlic-butter sauce. The final step is to shred the cooked squash and top it with the pan-seared garlic butter chicken.

The squash is a perfect low-carb swap for regular pasta that soaks up all the garlic sauce flavors. Not only does it taste amazing, but the spaghetti squash lightens it up and provides additional vitamins and fiber.

I also appreciate that the squash can be cooked, shredded, and refrigerated ahead of time. At dinnertime, all that’s left is to prepare the chicken portion, reheat the squash, and serve.

If you prep it ahead, you can cook the squash several different ways. While the microwave is the quickest method, roasting it in the oven adds delicious flavor and is equally simple. You can also make spaghetti squash in the slow cooker, to have it already prepped for you when you’re reading to cook. The choice is yours!

Garlic Chicken and Spaghetti Squash Ingredients

This dish is made with clean and simple ingredients. Aside from the spaghetti squash, most ingredients are already in your fridge and pantry.

spaghetti squash: a great low-carb substitute for spaghetti. The tender shreds of golden squash have a nutty flavor.
chicken breasts: use boneless, skinless chicken breasts or thighs.
Italian seasoning: to add flavor to the chicken and sauce.
olive oil: prevents the chicken from sticking to the skillet.
lemon juice: adds fresh citrus flavor.
unsalted butter: browns the garlic and creates a rich sauce that coats the chicken and squash.
garlic: an aromatic that gives the sauce a wonderful aroma and flavor.
half and half: makes the sauce super creamy.
red pepper flakes: for a little extra kick.
grated Parmesan cheese: aged, sharp Parmesan adds a whole new depth of flavor.
chopped fresh parsley: for garnish, definitely optional.

How to Make Garlic Butter Chicken with Spaghetti Squash

Are you ready to make one of the best chicken recipes of your life? Good! Let’s get to it.

Microwave the spaghetti squash
Cut the squash in half, scoop out the seeds, and prick the skin with a fork. Place one half into a baking dish, fill the cavity with water, and cover the second half. Microwave for 10 minutes or until the skin is softened and the squash shreds easily. See other methods of cooking spaghetti squash here, if you have more time.
Pan-sear the chicken
Season both sides of the chicken with Italian seasoning, salt, and black pepper. In a large skillet, sear the chicken until the internal temperature reaches 165F; squeeze the lemon juice over the chicken and set it onto a plate.
Homemade garlic butter
In the same skillet, brown the garlic with the butter, then slowly add in the half and half and seasonings. Stir in the Parmesan and continue to stir until the sauce is thickened. Add the chicken.
Serve
Use a fork to shred the spaghetti squash. Scoop the squash onto a plate and top with chicken, the garlic butter sauce, and chopped parsley.

Serving Chicken Spaghetti Squash

Leftover Spaghetti Squash and Chicken

In the rare case that you have leftovers, you can pack this meal away for a satisfying lunch or dinner later in the week. Place the squash and chicken in individual airtight containers and refrigerate for up to 3 days.

To reheat, add 1 to 2 tablespoons of water to the dish, cover with plastic wrap, and microwave for 2 to 3 minutes until the chicken is heated through and the squash is tender. *The plastic wrap creates a steaming effect which prevents the chicken and sauce from drying out.
