For Tuscan Chicken and Spaghetti Squash

Spaghetti Squash – This is the base of the dish and a low-carb alternative to pasta. Once cooked, it pulls into tender strands that soak up the creamy sauce beautifully.

Boneless, Skinless Chicken – Cut into bite-size pieces so it cooks quickly and evenly. Chicken breasts work well here, staying tender in the cream sauce.

Salt & Pepper – Simple seasoning to enhance the natural flavors of the chicken and sauce.

Italian Seasoning – Adds classic Tuscan-style herbs that tie the dish together.

Butter – Used to cook the chicken and build the base of the sauce, adding richness and depth.

Garlic – Brings bold, savory flavor and aroma to the dish.

Shallot – Milder and slightly sweeter than onion, it adds subtle complexity to the sauce.

Sun-Dried Tomatoes – These add a concentrated, slightly tangy flavor that balances the creaminess of the sauce.

For the Creamy Tuscan Sauce

Heavy Cream – Creates the rich, silky base of the sauce and coats every strand of squash.

Parmesan Cheese – Adds saltiness and umami while helping the sauce thicken slightly.

Baby Spinach – Wilts gently into the sauce, adding color, freshness, and nutrients.

Fresh Parsley (Optional) – A light, fresh garnish that brightens the finished dish.

Notes

Ingredients

1 medium spaghetti squash
1 pound boneless, skinless chicken, cut into bite-size pieces
salt
pepper
1 teaspoon Italian seasoning
2 tablespoons butter
4 cloves garlic, minced
1 shallot, minced
2 tablespoons sun-dried tomatoes, packed in oil, drained and julienned
1 cup heavy cream
1/3 cup Parmesan cheese, grated
3 ounces baby spinach
fresh parsley, optional, for garnish

Instructions

Use a knife to carefully pierce the spaghetti squash several times through the center. Place it on a microwave-safe plate and cook on high for 8–12 minutes, or until tender. Set aside to cool while preparing the chicken.
Season the chicken pieces with salt, pepper, and Italian seasoning.
Heat 1 tablespoon of the butter in a large, deep skillet over medium-high heat. Add the chicken and cook for about 7 minutes, until fully cooked and no longer pink inside.
Transfer the chicken to a plate and loosely cover with aluminum foil to keep warm.
Add the remaining butter to the same skillet. Stir in the garlic and shallot and cook for 1–2 minutes, just until fragrant and slightly softened.
Add the sun-dried tomatoes and cook for 1 additional minute.
Pour in the heavy cream and allow it to heat until bubbling gently, about 1–2 minutes.
Remove the skillet from the heat and stir in the Parmesan cheese and spinach. Return the chicken and any juices from the plate back into the pan.
Once the spaghetti squash is cool enough to handle, cut it in half lengthwise, scoop out the seeds, and use a fork to scrape the flesh into strands.
Add the squash to the skillet and toss until evenly coated in the cream sauce.
Garnish with fresh parsley if desired, then serve warm.

Notes & Tips

To streamline prep, the spaghetti squash can be cooked ahead of time and reheated before adding it to the sauce.
Oven roasting is another option for the squash: halve it lengthwise, remove the seeds, drizzle with olive oil, and season with salt and pepper. Roast at 350°F for 45–60 minutes, until tender.
Store leftovers in an airtight container in the refrigerator and enjoy within 3–5 days.

Save

1. Can I get anything ready ahead of time?

Absolutely. If you’re short on time, you can cook the spaghetti squash in advance and keep it in the fridge until you’re ready to use it. Garlic, shallot, and sun-dried tomatoes can also be prepped earlier in the day. Come dinner time, everything comes together fast.

2. What’s the easiest way to cook the spaghetti squash?

Microwaving is hands-down the quickest option—poke it, zap it, done. That said, if you love a slightly deeper, roasted flavor and have the time, the oven method works beautifully too. Both get you those lovely spaghetti-like strands.

3. Can I swap the chicken for something else?

Yes! This sauce is very forgiving. Shrimp is fantastic here (just cook it quickly and don’t overdo it), and turkey works well too. Think of the sauce as the star—you can build around it.

4. My sauce feels a bit thin—what should I do?

Easy fix. Let it bubble gently for an extra minute or two before adding the squash, or stir in a little more Parmesan. Once the cheese melts and the squash is added, everything thickens up nicely.

5. Is this a full meal on its own, or should I add a side?

It’s definitely filling enough to stand alone, but if you want to round it out, a simple green salad or some roasted veggies on the side are perfect. Nothing fancy needed—this dish already does a lot of the heavy lifting.
