Kittencal's Ground Beef-Mushroom Pasta Casserole

"I have listed the water as optional if you are using a thick rich prepared pasta sauce then add it in, adjust the chili flakes to suit heat level, for ease --- for ease I have canned mushrooms listed you may of coarse use fresh sauteed if desired."

  1. This actually took me and hour and half to prepare so time to make should be amended somewhat. Simmering the sauce alone is 45 mins. leaving only 10 to complete the rest of the recipe? The results were pretty good but it made so much that we had a lot of leftovers. I'll probably do this one again but will cut the recipe way back to serve only two of us. Thanks Kitten, as always your recipes are top notch.
  2. I'm assuming the oven temperature should be at 350 degrees. Easy to make since I had a jar of marinara sauce. I added fresh mushrooms while cooking the beef,onions and garlic. Cut down on the cheese a bit to cut down on the calories. Quick, satisfying meal. Thanks!
  3. Wow!!! What an easy and fabulous tasting dish, great comfort food. Made as posted and baked for 35 minutes @ 375 F. Came out nice and bubbly. Thanks for another wonderful pasta meal. *Made for Kittencal Cook-A-Thon*


  1. Yumminess although I did not simmer the sauce for more than 10 minutes. I like to tweak my marina sauce with 2 tsp of onion powder, some Italian seasoning, a bit of sweetener, and a 1/2 tsp garlic powder. Its a good ratio of pasta/meat/sauce. I will make this again and again I'm sure. Thanks for a great basic recipe!
