Philly Cheesesteak Spaghetti Squash Casserole Recipe

Cooking Directions

• STEP 1.Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
• STEP 2.Cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the halves cut-side down on the baking sheet and roast for 40-45 minutes, or until the flesh is tender.

• STEP 4.Push the onions and peppers to one side of the skillet and add the thinly sliced steak. Cook for 2-3 minutes, or until the steak is browned and cooked to your desired level of doneness.
• STEP 5.Using a fork, scrape the flesh of the roasted spaghetti squash into a large bowl. Add the cooked onions, peppers, and steak to the bowl and toss to combine.
• STEP 6.Transfer the mixture to a greased casserole dish and top with slices of provolone cheese.
• STEP 7.Bake for 10-15 minutes, or until the cheese is melted and bubbly.
• STEP 8.Serve hot and enjoy!

Cooking Tips

• Make sure to choose a spaghetti squash that feels heavy for its size and has a firm skin.
• For a shortcut, you can use pre-cooked steak or roast beef slices instead of cooking the steak from scratch.
• Feel free to customize the toppings by adding mushrooms, jalapenos, or any other ingredients you like in your Philly cheesesteak.

• Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
