Cheesy Twice-Baked Butternut Squash

(4)

These stuffed roasted butternut squash halves get the same treatment as a twice-baked potato, with a garlicky creamed spinach mixture blended together with the roasted squash. The mixture is scooped back into the skin, then broiled to melt the nutty Gruyère cheese on top. This sweet and savory dish is simple enough for a weeknight or makes an excellent vegetarian main course for your holiday table.

Whether you’re looking for a side to go with your main dish or a vegetarian main, this Cheesy Twice-Baked Butternut Squash is it! Sweet butternut squash becomes slightly caramelized and gets a creamy flavor spike from cream cheese infused with spicy garlic and woody sage and thyme. Antioxidant-rich baby spinach adds color and a mild grassiness, while nutty Gruyère gets all melty and is complemented by crunchy, toasty hazelnuts. A drizzle of sticky balsamic glaze finishes this dish off with style. Keep reading for our expert tips, including easy ingredient swaps.

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! 

  • Instead of homemade creamed spinach, you can use prepared spinach-artichoke dip. 
  • Pecans can be used instead of hazelnuts, or you can skip the nuts altogether. For the best flavor, toast nuts before using in a recipe. To toast hazelnuts, spread in a single layer in a small baking pan and bake in a 350°F oven until golden and fragrant, 5 to 7 minutes, stirring the nuts or shaking the pan once. Transfer to a small bowl or plate to cool before finely chopping.
  • Parmesan or aged white Cheddar can be used instead of Gruyère.
  • Instead of squash halves, you can use frozen, thawed mashed butternut squash. Combine it with the creamed spinach, spoon it into ramekins or a casserole dish, sprinkle with Gruyère and bake.

Nutrition Notes

  • Butternut squash is a hearty winter squash loaded with fiber, antioxidants, vitamins A and C, and potassium. Altogether, the nutrients in butternut squash have been linked to reduced inflammation and disease risk, healthy digestive and immune systems, and a healthy heart and blood pressure.
  • Baby spinach is rich in many of the same nutrients that butternut squash is rich in—fiber, antioxidants and vitamins A, C and K. The folate in spinach is important for healthy cell growth and function, and the antioxidants in spinach—lutein and zeaxanthin—support healthy vision. The vitamin C in spinach and butternut squash will help your body more easily absorb the iron from the spinach. 
  • Melty Gruyère cheese brings protein, calcium and vitamin B12 to this dish. Cheese is also a good source of probiotics—those beneficial gut bacteria necessary for a healthy, flourishing microbiome.
  • Hazelnuts are a type of nut loaded with healthy unsaturated fats. Nuts also provide antioxidants for reducing inflammation, complex carbs for energy, and fiber to help keep things moving along. The combo of fiber, plant protein and fat in nuts helps to keep you satisfied and full longer. Regularly including nuts in your diet has been linked to lower cholesterol levels and a healthy heart.

Ingredients

  • 1 (2-pound) butternut squash, halved lengthwise and seeded

  • 3 teaspoons extra-virgin olive oil, divided

  • 2 teaspoons minced garlic

  • 1 teaspoon chopped fresh thyme, plus additional leaves for garnish

  • 1 teaspoon chopped fresh sage, plus small leaves for garnish

  • 3 cups baby spinach (3 ounces)

  • 2 ounces reduced-fat cream cheese, softened

  • ½ teaspoon ground pepper

  • ¼ teaspoon salt

  • ½ cup shredded Gruyère cheese

  • ¼ cup finely chopped toasted hazelnuts

  • 1 tablespoon balsamic glaze

Directions

  1. Preheat oven to 400°F with a rack 6 inches from broiler. Line a large rimmed baking sheet with foil.

  2. Brush cut sides of squash halves with 1 teaspoon oil; place cut-sides down on the prepared baking sheet. Roast until fork-tender, 30 to 35 minutes. Let cool slightly on the baking sheet. Turn on the broiler.

  3. Meanwhile, heat the remaining 2 teaspoons oil in a large nonstick skillet over medium heat. Add 2 teaspoons garlic and 1 teaspoon each thyme and sage; cook, stirring constantly, until fragrant, about 1 minute. Add 3 cups spinach; cook, tossing or stirring constantly, until wilted, about 1 minute. Stir in 2 ounces cream cheese, ½ teaspoon pepper and ¼ teaspoon salt; cook, stirring constantly, until the cream cheese is melted and coats the spinach, about 1 minute. Remove from heat.

  4. Scoop out the squash flesh, leaving a ¼-inch border, and place in a large bowl; mash with a fork or spoon until smooth. Fold the spinach mixture into the mashed squash until fully combined. Spoon into the squash shells (about 1 cup per half). Sprinkle with ½ cup Gruyère.

  5. Return the stuffed squash halves to the foil-lined baking sheet; broil until the cheese is melted and browned, 2 to 3 minutes. Top with ¼ cup hazelnuts and drizzle with 1 tablespoon balsamic glaze. Cut the squash halves in half to serve. Garnish with thyme and sage leaves, if desired.

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.)
