This dish was very good , I also put my own twist to it one thing i did is i cooked the squash in the pressure cooker for 5 minuets with some seasonings, it raked out of the skin beautifully I used cheddar cheese and some baby spinach cooked it at 375 degrees in the oven came out awesome my wife couldn't believe it, very good recipe.

Extremely hearty and flavorful, and a good solution for low-carb diets when real pasta is not allowed. I agree with the others who noted the not-so-pretty appearance of the dish. My solution was to not mix everything up---keep the spaghetti squash in a separate dish, toss with a bit of butter, and serve the other vegetables in the sauce on top of the squash. Much more attractive!

Very good. Agree that this is not a pretty looking dish, but the taste is great. I used canned mushrooms, didn't have fresh, and added a few TBSP of homemade marinara as I only had a few fresh grape tomatoes. I also added a good heavy pinch of crushed red pepper to give the dish a bit of zip. I used cottage cheese as that is what I had, might try ricotta next time to make it look a bit prettier. Overall a keeper, I had it as a filling main dish for just me, would probably pair it with some grilled chicken or pork for my carnivore family. Thanks for posting!
