Tips from the EatingWell Test Kitchen

These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too! 

  • A very sharp chef’s knife is the best way to cut the spaghetti squash into even rounds. If the squash has a particularly tough skin, pierce it with a fork in 4 or 5 different places and microwave it for 3 to 4 minutes to soften it for slicing.
  • Scraping around the squash rings in a circular motion will create nice, long strands of squash.
  • You can use white-wine vinegar instead of the white balsamic vinegar and sub curly kale or spinach instead of the lacinato kale.
  • Use a spatula to transfer the nests to a plate to avoid everything falling out the bottom, or remove the squash skin and serve in a bowl. 

Nutrition Notes

  • Spaghetti squash is the delicious, low-carb base of this recipe. Since it’s filled with B vitamins, eating this type of squash is great for your metabolism. It also contains potassium, calcium and fiber—all important nutrients for heart health. Spaghetti squash is a hydrating vegetable that also adds a delicious texture to any savory meal. 
  • Mushrooms are a source of B vitamins and plant-based protein, which help to maintain a good metabolism. Your mushrooms may also be a source of vitamin D if they were grown in ultraviolet light—look for it on the label. Vitamin D is an inflammation-lowering nutrient and is essential for your body to absorb calcium. 
  • Kale is a powerhouse of antioxidants—vitamin C for lowering inflammation and lutein and zeaxanthin for healthy eyesight and vision. Kale is also high in vitamin K, which is essential for proper blood clotting, which is important to remember if you are on blood-thinning medication. 
  • Cannellini beans are a source of muscle-building plant-based protein. They are also an excellent source of fiber—great for your digestive health. When choosing your canned beans, you can look for no- or low-sodium beans or rinse your beans after draining to keep sodium levels low—important for heart health.

Ingredients

Original recipe (1X) yields 4 servings

  • 1 large spaghetti squash (2½ to 3 pounds)

  • 6 tablespoons extra-virgin olive oil, divided

  • 1 (8-ounce) package sliced cremini mushrooms (about cups)

  • ¾ teaspoon salt, divided

  • 4 teaspoons white balsamic vinegar

  • 1 teaspoon Dijon mustard

  • 2 cups loosely packed stemmed and chopped lacinato kale

  • ¼ teaspoon crushed red pepper

  • 1 (15-ounce) can no-salt-added cannellini beans, rinsed

  • 4 teaspoons grated Parmesan cheese

  • 2 teaspoons chopped fresh oregano

Directions

  1. Preheat oven to 425°F. Trim squash ends and cut squash crosswise into 4 equal rounds, about 1½ to 2 inches wide. Scoop out seeds and discard. Place the squash rounds on a large rimmed baking sheet; brush the cut sides and interior with 1 tablespoon oil. In a small bowl, combine 1 (8-ounce) package sliced mushrooms, 1 tablespoon oil and ¼ teaspoon salt; toss to coat. Spread in an even layer around the squash rounds. Roast for 20 minutes.

  2. Meanwhile, whisk 4 teaspoons vinegar, 1 teaspoon mustard and ¼ teaspoon salt together in a small bowl. Gradually whisk in 3 tablespoons oil until smooth. Set aside, uncovered, at room temperature until ready to use.

  3. Divide 2 cups chopped kale among the centers of the squash rings; drizzle the kale with the remaining 1 tablespoon oil and sprinkle with ¼ teaspoon crushed red pepper. Roast for 10 minutes. Sprinkle rinsed beans around the squash rings; roast until the squash is tender, the kale is wilted, the mushrooms are browned and the beans are heated through, about 5 minutes.

  4. With a fork, shred the squash in the centers of the rings into long strands; gently stir to distribute the kale evenly. Sprinkle with the remaining ¼ teaspoon salt. Divide the mushrooms and beans among the squash nests (about ½ cup each). Drizzle with the vinaigrette and sprinkle with 4 teaspoons Parmesan and 2 teaspoons oregano.

Frequently Asked Questions

  • How do I choose the best spaghetti squash?

    You want to choose the best-looking and heaviest spaghetti squash available. The ideal color is golden yellow, and the skin should be smooth, matte and free of blemishes. Also, check the stem—it should be dry and never green.

  • What should I serve with spaghetti squash nests?

    These spaghetti squash nests are an excellent vegetarian main dish. Pair them with your favorite side salad to round out the meal.

  • Is this recipe vegetarian?

    Yes, as long as you use vegetarian Parmesan cheese that isn’t made with animal rennet. If you’re following a strict vegetarian diet, it’s important to check Parmesan labels as it’s traditionally made using animal rennet enzymes, though vegetarian versions made with vegetable-based enzymes can also be found at the supermarket.

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.)
