Ingredients

  • Olive oil cooking spray [I use my EVO]
  • 1 lb spicy Italian turkey sausage casings removed
  • 1/4 onion diced
  • 2 cloves garlic minced
  • 1 1/4 cup ricotta cheese WW can use fat free
  • 1 egg
  • 1 1/2 cups homemade tomato sauce or a no sugar added jarred sauce like Rao's
  • 1 cooked spaghetti squash about 4 cups of squash
  • 2/3 cup mozzarella cheese
  • 1 tablespoon parmesan cheese
  • Fresh basil
  • Salt and pepper

Instructions

  • Spray a pan with olive oil cooking spray, saute onion until soft. Add turkey sausage and brown until cooked through. Add garlic and cook for an additional minute. Remove from heat.
  • Discard seeds from the squash and use a fork to remove your "spaghetti." To remove excess moisture from the squash, place it in a clean kitchen towel and give it a squeeze. Then season the squash with a little salt and pepper.
  • Stir an egg, parmesan cheese, and a sprinkle of pepper into the ricotta.
  • Preheat your oven to 375 degrees F. Spray a casserole dish with a olive oil cooking spray and begin the layering process.
  • First, spoon about half of your sauce on the bottom of the casserole dish.
  • Next, add the cooked sausage. Layer spaghetti squash over the sausage then add the rest of the sauce and some fresh chopped basil.
  • Finally, top sauce with the ricotta cheese mixture and then add the shredded mozzarella.
  • Bake until cheese is melty and bubbly - about 15-20 mins. To brown the cheese, broil on low for 5-10 minutes at the end, but watch carefully. It sneaks up on you!
  • Remove from oven and let sit for a few minutes. If there is excess water at the bottom of your pan, you can carefully try to drain it out from the corner of the pan or serve with a slotted spoon.
  • Garnish with fresh basil before serving!

Notes

21 Day Fix: 1 1/2 RED, 1/2 BLUE, 1 1/2 GREEN (per serving)
WW: 9 points (per serving) [Calculated using hot italian turkey sausage, part skim mozzarella cheese, and fat free ricotta cheese]
To Prep Ahead:
  • This Spaghetti Squash Lasagna is an excellent candidate for meal prep. You can assemble it up to 24 hours before baking.  Just follow the recipe instructions up to the point of baking, then cover the baking dish with foil and refrigerate. When you're ready to enjoy it, simply bake as directed.
  • Another option is to prep the tomato sauce, squash and meat/veggie mixture up to three days in advance.  Then all you have to do is assemble and bake the lasagna the day you want to eat it. 
To Store:
  • If you have leftovers or want to store a fully cooked lasagna, allow it to cool to room temperature. Store any remaining lasagna in an airtight container in the refrigerator for up to 3-4 days.
To Freeze:
  • To freeze Spaghetti Squash Lasagna, wrap individual portions or the entire dish tightly with plastic wrap or aluminum foil. Place the wrapped lasagna in an airtight container or a resealable freezer bag to prevent freezer burn. Frozen lasagna can be stored for 2-3 months.
To Reheat:
  • Reheat in a preheated oven at 350°F until the lasagna is heated through, typically about 15-20 minutes for individual portions or 30-40 minutes for the entire dish.
  • Alternatively, you can microwave individual servings on a microwave-safe plate for 2-4 minutes or until hot.  
  • To reheat frozen lasagna, it's best to thaw it in the refrigerator overnight and then follow the reheating instructions above.
