Chicken & Spaghetti Squash Recipe

While dreaming up a healthier pasta dish, I decided to experiment with spaghetti squash. After a few tries, I settled on this delicious casserole bursting with flavor but not fat. Christina Morris, Calabasas, California
TOTAL TIME: Prep: 45 min. Bake: 20 min. YIELD:5 servings


  • 1 medium spaghetti squash (4 pounds)
  • 1 can (14-1/2 ounces) diced tomatoes, undrained
  • 2 tablespoons prepared pesto
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon Italian seasoning
  • 1/4 cup dry bread crumbs
  • 1/4 cup shredded Parmesan cheese
  • 1 pound boneless skinless chicken breasts, cut into 1/2-inch cubes
  • 1 tablespoon plus 1 teaspoon olive oil, divided
  • 1/2 pound sliced fresh mushrooms
  • 1 medium onion, chopped
  • 1 garlic clove, minced
  • 1/2 cup chicken broth
  • 1/3 cup shredded cheddar cheese


  • 1. Cut squash in half lengthwise; discard seeds. Place squash cut side down on a microwave-safe plate. Microwave, uncovered, on high for 14-16 minutes or until tender.
  • 2. Meanwhile, in a blender, combine the tomatoes, pesto, garlic powder and Italian seasoning. Cover and process until blended; set aside. In a small bowl, combine bread crumbs and Parmesan cheese; set aside.
  • 3. In a large skillet, cook chicken in 1 tablespoon oil until no longer pink; remove and keep warm. In the same skillet, saute mushrooms and onion in remaining oil until tender. Add garlic; cook 1 minute longer. Stir in the broth, chicken and reserved tomato mixture. Bring to a boil. Reduce heat; simmer, uncovered, for 5 minutes.
  • 4. When squash is cool enough to handle, use a fork to separate strands. In a large ovenproof skillet, layer half of the squash, chicken mixture and reserved crumb mixture. Repeat layers.
  • 5. Bake, uncovered, at 350° for 15 minutes or until heated through. Sprinkle with cheddar cheese. Broil 3-4 in. from the heat for 5-6 minutes or until cheese is melted and golden brown. Yield: 5 servings.

"This was delicious. Followed advice from others, drained spaghetti squash, added diced zucchini . I used Italian diced tomatoes, doubled the sauce recipe, and 1 1/2 lbs of diced chicken. My husband likes a lot of meat and sauce. I would make this again and may add carrots next time."

"This was much better than eating spaghetti squash only with sauce! We used precooked, coated chicken strips & grated Parmesan cheese. It was not watery. Could have used more sauce, though."

"@ sirsingalot...whenever using spaghetti squash, ALWAYS place shredded squash directly into a colander & allow it to drain before using/eating. Otherwise you will have a watery outcome!"

"This was ok for me but I found it a bit watery. Definitely needed more salt or hot pepper flakes to kick it up a notch. First experience with Spaghetti Squash, but will work with it again sometime. I didn't have shredded Parmesan so I substituted grated mozzarella cheese. Maybe that made a difference, I don't know. Any suggestions on how to fix this to make it better and did anyone else have a "watery" problem?"

"This was great! All the flavors melded in perfectly. My husband was hesitant at first to try, but was pleasantly surprised afterward. We only added a bit of salt to suit our taste, but is still great as-is (and healthier w/out salt!)."
