Ingredients

  • 6 ounces whole-wheat pasta, such as rotini or elbows

  • 3 tablespoons extra-virgin olive oil, divided

  • 1 small onion, chopped

  • 8 ounces white mushrooms, halved if large, sliced

  • ½ teaspoon salt, divided

  • ½ teaspoon ground pepper, divided

  • 2 cloves garlic, minced

  • 2 tablespoons all-purpose flour

  • 1 ½ cups whole milk

  • 1 teaspoon Dijon mustard

  • ¾ cup grated Parmesan cheese, divided

  • 2 cups chopped or shredded cooked chicken

  • 1 (10 ounce) package frozen chopped spinach, thawed and squeezed dry

Directions

  1. Preheat oven to 400°F.

  2. Bring a large pot of water to a boil. Add pasta and cook according to package directions. Drain and set aside.

  3. Meanwhile, heat 2 tablespoons oil in a large ovenproof skillet over medium heat. Add onion; cook, stirring, until softened, about 2 minutes. Add mushrooms and 1/4 teaspoon each salt and pepper; cook, stirring, until softened, 4 to 6 minutes. Add garlic; cook, stirring, for 1 minute. Transfer the mixture to a large bowl.

  4. Add the remaining 1 tablespoon oil to the pan. Sprinkle in flour; cook, stirring, for 1 minute. Gradually add milk and mustard; cook, whisking constantly until the sauce thickens, 2 to 3 minutes. Remove from heat and stir in 1/2 cup Parmesan and the remaining 1/4 teaspoon each salt and pepper. Add the pasta, chicken, spinach and the mushroom mixture. Stir until well coated. Smooth the top and sprinkle with the remaining 1/4 cup Parmesan.

  5. Bake until bubbling, about 15 minutes.

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.)
