Ingredients

Spaghetti Squash:

  • 1 large spaghetti squash cut in half, seeds removed
  • 2 Tbsp. oil olive or avocado
  • ½ tsp. salt
  • ¼ tsp. pepper

Lasagna Filling:

  • 2-3 Tbsp. oil olive or avocado
  • 2 cloves garlic
  • 1 small sweet onion finely chopped
  • 1 small green bell pepper finely chopped
  • 1 lb. ground beef 93/7
  • 24 oz. spaghetti sauce
  • 2 tsp. Italian seasoning
  • 1 tsp. salt
  • ¼ tsp. pepper
  • 1 cup ricotta cheese
  • 1 cup mozzarella cheese
  • Parmesan grated, optional
  • Parsley finely chopped, optional

Instructions

  • Bake Spaghetti Squash: Preheat oven to 425°F. Cut one large spaghetti squash in half, lengthwise. Scoop out and discard seeds. Drizzle 1 tablespoon olive oil in each half of the squash and sprinkle with equal amounts of salt and pepper. Place halves face-down on a parchment paper or aluminum foil-lined baking sheet. Roast squash in preheated oven for 45-50 minutes, or until squash is tender and shreds easily with a fork.
    1 large spaghetti squash, 2 Tbsp. oil, ½ tsp. salt, ¼ tsp. pepper
  • Make the Filling: While the squash is baking, combine olive oil, garlic, onions, and bell peppers in a medium-sized skillet over medium heat. Sauté for 3-4 minutes. Push vegetables to the side of the skillet and add ground beef. Cook beef over medium heat for 6-8 minutes, or until meat is cooked through. Add spaghetti sauce, Italian seasoning, salt and pepper. Stir until combined. Reduce heat to low, cover and simmer for 5 minutes.
    2-3 Tbsp. oil, 2 cloves garlic, 1 small sweet onion, 1 small green bell pepper, 1 lb. ground beef, 24 oz. spaghetti sauce, 2 tsp. Italian seasoning, ¼ tsp. pepper, 1 tsp. salt
  • Make the Boats: Once spaghetti squash is completely cooked, shred the inside of each half with a fork to form “noodles.” Divide the ground beef sauce evenly between the two halves of the spaghetti squash. Next, add 4 oz. ricotta cheese into each boat. Lastly, top each half with ½ cup mozzarella cheese.

  • Bake and Serve: Return spaghetti squash boats to the oven and continue baking for 5-10 minutes, or until cheese melts and begins to brown. Serve with Parmesan and parsley and enjoy!

Notes

Prep-Ahead Instructions:
Feel free to bake the spaghetti squash a day or two early and make the filling, but keep them separate.
Storage Directions:
You can store any leftovers in an airtight container in the refrigerator for up to 3-4 days.
This recipe will also freeze well when stored in freezer-safe containers for up to 6 months. Just note, the spaghetti squash "noodles" will get quite a bit watery after thawing.
If you'd like, you can cook and prepare the meat sauce and freeze that.  When you're ready to thaw it out simply bake a spaghetti squash, add in the meat sauce and cheeses, and serve away!
Recipe Tips
  • Just enough. Don't overdo it with the oil or salt before baking the squash or it will be mushy.
  • Save time. It's so quick and easy to buy a bottle of sauce from the grocery store.
  • Less is best. Look for a meat with a lower fat ratio for the best results.
  • Pay attention. Grab a squash that is medium-sized for the most flavor and appealing texture in "noodles."
