You guys are seriously going to LOVE this spaghetti squash pizza casserole!  When eating low carb, I find that the foods people tend to crave the most are pizza and pasta.  Well this recipe satisfies those cravings, without all the carbs (and guilt)!  This is true comfort food at its finest and a meal even my picky toddler loves.  Roasted spaghetti squash that is scraped out of the shell resembles (in my opinion) angel hair pasta and the great thing is that spaghetti squash on its own lacks a lot of flavor so you can pretty much add it to any dish or sauce and it works great!

I’ve always loved using spaghetti squash in the place of pasta and since pizza is one of my husband’s favorite guilty pleasures, I thought this would be the perfect combo for a delicious weeknight meal.  This an easy dish to throw together using just a few simple ingredients and I’m certain your family will love it!

INGREDIENTS YOU’LL NEED

  • Spaghetti Squash
  • Ground beef or turkey (you could use ground chicken too or keep this meatless!)
  • Favorite marinara (I love Rao’s)
  • Onion
  • Garlic
  • Italian herbs
  • Mozzarella cheese
  • Pepperonis
  • Red pepper flakes (optional)

I kept this recipe pretty simple and classic, but you could also add in other veggies such as chopped bell pepper or mushrooms, and have fun by adding all your favorite pizza toppings!  My husband loves olives, but I’m not a fan so I left them out 😉  I also like to top this with fresh basil or parsley!

HOW TO MAKE SPAGHETTI SQUASH PIZZA CASSEROLE

  1. Roast spaghetti squash.  To roast the squash, cut the squash in half lengthwise (making sure to use a good knife) and scoop out all the seeds.  Brush with just a little bit of olive oil, sprinkle with salt and pepper, then place both halves cut side down on a baking sheet.  Bake in the oven at 375 degrees F for about 35 to 40 minutes.
  2. Make your meat sauce.  While the squash is roasting, sauté the onion and garlic in a large skillet with a little olive oil then add the ground beef and cook until crumbled and browned.  Stir in the seasonings, salt and pepper, then pour in the marinara and mix until everything is combined.  Bring the sauce to a boil, then reduce heat and let the sauce simmer for about 10 minutes.
  3. Shred spaghetti squash.  Remove squash from the oven and let cool for a few minutes until it’s easier to handle.  Using a fork, scrape out all the insides of the squash and add to the sauce that’s simmering on the stove.  Toss with the meat sauce and cook for about 3 minutes, just so all those flavors can heat through.
  4. Assemble pizza casserole.  Transfer the spaghetti squash and meat sauce to a 9×13 casserole dish lightly coated with nonstick spray.  Top with shredded mozzarella cheese, arrange pepperonis and sprinkle with additional Italian seasoning (and red pepper flakes if you like a little spice!)
  5. Bake and enjoy!  Pop the pizza casserole in the oven (uncovered) and bake at 375 degrees F for about 25 minutes.  Serve and enjoy!
