Chicken Parmesan-Stuffed Spaghetti Squash

This filling, hearty stuffed spaghetti squash is a lower-carb version of your traditional chicken Parmesan with pasta. This chicken Parmesan recipe is still full of cheesy goodness, but has the added benefit of sweet winter squash. If you can't find two small squashes, use one (3-pound) squash and cut each half into two portions when ready to serve.

Nutrition Profile:


  • 2 (1 1/2 pound) spaghetti squashes

  • 1 ½ tablespoons olive oil

  • 1 pound boneless.skinless chicken breasts, cut into 1-inch cubes

  • 2 cups chopped yellow onion

  • 5 cloves garlic, chopped

  • 1 cup lower-sodium marinara sauce

  • ½ teaspoon crushed red pepper

  • ¼ cup shredded low-moisture, part-skim mozzarella cheese

  • ¼ cup grated Parmesan cheese


  1. Preheat oven to 400 degrees F. Cut squash in half lengthwise; scoop out and discard seeds. Place squash, cut-side down, on a parchment paper-lined rimmed baking sheet. Bake until tender when pierced with a knife, about 40 minutes. (Alternatively, place 2 squash halves in a large microwaveable dish with 2 tablespoons water; microwave on High until tender when pierced with a fork, about 11 minutes. Repeat with the remaining squash halves.) Let the squash cool for 10 minutes. Scrape out the strands with a fork, leaving a 1/2-inch border on the sides and bottom of each shell. Place the squash strands in a large bowl and set aside.

  2. Increase oven temperature to 450 degrees F. Heat oil in a large skillet over high heat. Add chicken; cook, stirring occasionally, until just browned, about 2 minutes. Add onion and garlic; cook, stirring occasionally, until soft, about 4 minutes. Remove from heat; stir in marinara sauce and crushed red pepper. Add the chicken mixture to the bowl with the squash; toss to combine. Spoon the mixture evenly into the squash shells. Top with mozzarella and Parmesan.

  3. Bake until the cheese is melted, 8 to 10 minutes. Let stand for 5 minutes before serving.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
