  • Place squash on a baking sheet, and bake 40 minutes, or until tender. Remove from heat, cool, and shred pulp with a fork.

  • Reduce oven temperature to 350 degrees F (175 degrees C). Lightly grease a casserole dish.

  • In a skillet over medium heat, cook the ground beef until evenly brown. Drain, and mix in the green pepper, red pepper, red onion, and garlic. Continue to cook and stir until vegetables are tender.

  • Mix the shredded squash and tomatoes into the skillet, and season with oregano, basil, salt, and pepper. Cook and stir until heated through. Remove skillet from heat, and mix in 2 cups cheese until melted. Transfer to the prepared casserole dish.

  • Bake 25 minutes in the preheated oven. Sprinkle with remaining cheese, and continue baking 5 minutes, until cheese is melted.

Cook's Note:

You can use bulk sausage in place of the ground beef, if you prefer.

Fantastic! I did not change a thing and this recipe was perfect. I cut the squash in half lengthwise, scooped out the seeds, then microwaved cut side down in 1/4 inch of water in a casserole dish for 13 minutes. It turned out just right in less than half the time. Read More

This recipe definitely needs some tweaking. A little on the bland side. The salt shaker was making it's way around the table at our house. I love the kid-friendliness of this squash though. I told them it was spaghetti and they did not question it.:) Would not make it again as is but there is something to build on here... Read More

This is really tasty. I did have to change a few things because of my diet. Used Ground Turkey, Cabot 50% light cheddar cheese from Sam's (melts good), and I cut the squash in half, covered with plastic wrap and baked 10 min in microwave. (faster than oven) Read More

This recipe is awesome!! My brother in law loved it and he doesn't eat veggies. I doubled the meat because that's what my husband likes, the extra lb was hot italian sausage. I used italian seasoning instead of the individual ones , ended up using 1 1/2 cans of tomatoes because of the added meat and doubled the cheese. YUM!!! I can't wait for a party so I can suprise everyone with this dish! Original recipe would have been perfect too, just changed it for my family's tastes. Thanks!! Read More

Very good base recipe if a little bland - it needs a little tweaking to be truly delicious. Next time I'll increase the onion and all the seasonings add a little cayenne pepper for zing and throw in a can of tomato paste and some sliced mushrooms. A few tips: Start with a big pot - the recipe as-is was waaay too big for my skillet and I had to transfer it to a soup pot halfway through. Also the toasted seeds of the spaghetti squash made a great snack. I coated them with a teaspoon of butter and some Worcestershire sauce ground mustard garlic powder paprika and salt then toasted them for 25 minutes while the casserole was in the oven (stirring halfway through). Fabulous! Read More

This was excellent using homegrown spaghetti squash! Instead of using the nutritional info (it seemed high) I figured this out according to my weight watchers points system. This made 8 cups of food and each half cup serving was 4 points...a great meal in my book! Thanks for posting this! Read More

This dish is delicious! If no one told you that the "noodles" were squash you would swear it was pasta. It doesn't have that squashy taste. The dish was easy to prepare and very flavorful. I think the cooking time should be reduced a little bit maybe to only 20 minutes but otherwise I recommend it highly! Read More

This was great! I used zucchini instead of the bell pepper and mozzarella cheese. It was excellent and good leftover as well. Will definitely make again. Read More

My husband really liked this. I didn't have diced tomatoes so I used crushed and it was really good. I also substituted slices of chicken for the ground beef and my husband noted that the chicken "made the dish." Read More

Great recipe for using spaghetti squash. To make it easier to cut the squash cook whole in microwave for five to seven minutes. Take out cut and return halves to microwave to finish cooking another 10 to 7 minutes or so. This is so much easier than trying to cut through a raw squash. Save seeds. These are delicious baked in the oven with a little salt and/or pepper or seasoning of your choice. Read More
