Ingredients in pesto spaghetti squash

The spaghetti squash will act as its own bowl in this amazing dish. Just grab a fork and start eating! Besides a spaghetti squash for every two people who will be eating (you each get half), you’ll need these ingredients:

  • Chicken breasts
  • Red onion
  • Red pepper
  • Pesto
  • Bocconcini cheese

Pretty simple ingredient list right?!

Chicken Pesto Spaghetti Squash

How to make stuffed spaghetti squash

This is a pesto spaghetti squash simple recipe with just a few steps. Most of the cooking is hands-off in the oven.

  1. Prepare the spaghetti squash. Make a dotted line along where to plan to cut the squash. Microwave it for about three to five minutes to soften the skin. Follow the prepared line and cut the squash in half. Scoop out the seeds. Season the squash with olive oil, salt and pepper.
  2. Bake the spaghetti squash for 35 minutes at 425F.
  3. Dice the chicken breasts and saute in oil.
  4. Add red onion and red pepper to the pan.
  5. Toss with pesto and remove from heat.
  6. Scrape the spaghetti squash with a fork to make long strands.
  7. Mix chicken with the spaghetti squash and top with cheese.
  8. Bake for ten minutes until the cheese melts.

Ingredient substitutions

You can easily substitute other kinds of meat for the chicken in this pesto spaghetti squash recipe. Cubes of turkey, pork or beef will all work. Some may take a little longer to cook than others through. If you want to make this a vegetarian dish, you can omit the meat and double the veggies and cheese.

You can add more veggies or substitute for ones you like better. Any of these taste great with spaghetti squash:

  • Tomatoes
  • Mushrooms
  • Carrots
  • Olives
  • Spinach or kale
  • Broccoli
  • Eggplant
  • Zucchini

You can also change up the sauce you use. You could replace the pesto with balsamic vinegar or a tomato based pasta sauce, or even jarred alfredo sauce!

Making it in the Instant Pot

If you want to make pesto spaghetti squash even quicker, you can use your Instant Pot to cook the squash.

  1. Pour a cup of water into the bottom of the Instant Pot. The Instant Pot works when the water creates steam and builds pressure inside the pot.
  2. Place the trivet inside the pot. While you need the water, you don’t want your squash to sit in it and get soggy.
  3. You don’t even need to cut the squash. Just pierce it a few times with a knife so that it vents and put the whole thing on the trivet.
  4. Set the Instant Pot to cook on high pressure for 15 minutes. This will perfectly cook at three pound squash. If yours is especially big, you can add another three minutes to the cooking time.
  5. Allow the pressure to release naturally for at least ten minutes.
  6. Remove the squash. Cut it in half and remove the seeds. Then you can scrape it into noodles.

What to serve with spaghetti squash

This chicken spaghetti squash recipe has protein and lots of veggies. A serving size is one-half of a squash with lots of stuffing. This makes a great lunch or a light dinner. Other dishes that go well with spaghetti squash are:

  • Meatballs – just like spaghetti!
  • Bacon and fried eggs
  • Pork chops
  • Any type of roast
  • Shrimp
  • Seared scallops

If you choose to make this spaghetti squash as is, you can just serve a side salad or some garlic bread as a delicious side in case you aren't interested in keeping this dish low carb.

Extra topping ideas

If you want to really heap on the flavors, find other toppings for your pesto spaghetti squash.

Replace an ingredient that you don’t love or add more goodness to the recipe with any of these options:

  • Garlic
  • Parmesan cheese and butter
  • Cream sauce
  • Goat cheese
  • Parsley and basil

Chicken Pesto Spaghetti Squash

Storing & reheating this recipe

A cooked spaghetti squash can be stored in the refrigerator for up to one week. Once the toppings are all together and inside the squash, you should eat it within four to five days because it contains meat.

The best way to reheat pesto spaghetti squash is in the oven so the squash does not get mushy. However, you can put it in the microwave for a minute at a time until it is warm all the way through.

Freezing spaghetti squash

If you want to prepare more than one spaghetti squash at a time, you can freeze what you have left. The best way to do this is to cook the squash and use your fork to create noodles. Remove the noodles from the shell and store them in an airtight container or bag. I recommend you let the strands sit in a colander before storing them to let any extra moisture drain off.

Spaghetti squash is good for eight months when stored this way.

Spaghetti squash is best if you let it thaw completely before reheating. Let it sit in the refrigerator overnight to thaw. Then you can use it in any recipe, including mixing it with chicken and pesto like this recipe.

    Hey there! I am so excited to try this recipe as I LOVE spaghetti squash. The store that I shop at does not have bocconcini cheese, so is there another cheese that would work really well with this recipe?
