6 servings


  • 1 tablespoon olive oil

  • 2 cups diced butternut squash (3/4-inch; 10 oz.)

  • 1 shallot, minced

  • 4 cups thinly sliced stemmed kale, preferably lacinato

  • 1 tablespoon water

  • 8 large eggs

  • 3 large fresh sage leaves, minced, plus extra for serving

  • ¼ teaspoon salt

  • ¼ teaspoon ground pepper

  • ¼ cup crumbled goat cheese

  • 6 slices whole-wheat bread, toasted


  1. Preheat oven to 400 degrees F.

  2. Heat oil in a medium nonstick ovenproof or cast-iron skillet over medium-high heat. Add squash and cook, stirring occasionally, until just fork-tender, about 10 minutes. Add shallot; cook for 1 minute. Stir in kale by the handful. Add water; cover and reduce heat to medium-low. Cook until the kale is tender, about 5 minutes. Remove from heat; spread the mixture evenly in the pan.

  3. Whisk eggs, sage, salt, and pepper in a large bowl. Pour the egg mixture over the squash and kale in the pan. Sprinkle evenly with cheese. Bake until set in the center, 8 to 12 minutes.

  4. Holding the pan over a cutting board and using a large spatula, lift and slide the frittata out of the pan and onto the cutting board. Cut into wedges and sprinkle with sage. Serve with toasts.


To make ahead: Prepare squash and kale (Step 2) and refrigerate for up to 1 day.

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.)
