Kielbasa-&-Swiss Spaghetti Squash Casserole


Zesty sauerkraut, Swiss cheese and rye bread add Reuben-esque flavor to this surprisingly addictive spaghetti squash skillet recipe. If you can't find seeded rye bread, add 1/2 to 1 teaspoon caraway seeds to the mixture in Step 2. Serve with a green salad tossed with red-wine vinaigrette.

Nutrition Profile:


  • 1 2 1/2- to 3-pound spaghetti squash, halved lengthwise and seeded

  • 2 large eggs, beaten

  • 1 cup refrigerated sauerkraut, squeezed dry and chopped

  • 1 cup fresh rye breadcrumbs, preferably seeded rye

  • ½ cup chopped turkey kielbasa (3 ounces)

  • 1 bunch scallions, sliced, white and green parts separated

  • ¼ teaspoon ground pepper

  • 2 tablespoons extra-virgin olive oil

  • ½ cup shredded Swiss cheese


  1. Place squash cut-side down in a microwave-safe dish; add 2 tablespoons water. Microwave, uncovered, on High until the flesh is tender, about 10 minutes. (Alternatively, place squash halves cut-side down on a rimmed baking sheet. Bake in a 400 degrees F oven until the squash is tender, 40 to 50 minutes.)

  2. Meanwhile, combine eggs, sauerkraut, breadcrumbs, kielbasa, scallion whites and pepper in a large bowl. Let the squash cool for about 10 minutes, then use a fork to scrape it from the shells into the bowl with the sauerkraut mixture.

  3. Position rack in upper third of oven; preheat broiler.

  4. Heat oil in a large cast-iron or enamel-coated skillet over medium-high heat. Spread the squash mixture evenly in the skillet. Reduce heat to medium and cook, undisturbed, until browned on the bottom, 5 to 8 minutes. Sprinkle with cheese and the reserved scallion greens. Broil until browned on top, 4 to 6 minutes.


Cut Down on Dishes: A rimmed baking sheet is great for everything from roasting to catching accidental drips and spills. For effortless cleanup and to keep your baking sheets in tip-top shape, line them with a layer of foil before each use.

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.)
