Instructions

Preheat the oven to 400F and line a baking sheet with parchment paper. Cut the ends of the squash and carefully slice in half lengthwise. Scoop out the seeds, drizzle with olive oil, and season with salt and pepper. Arrange cut-side down and bake until tender, 30-45 minutes. Remove from the oven and let cool slightly. Use a fork to scrape the squash and create long spaghetti-like strands.

Towards the end of the squash baking, cook onion and mushroom in a large pan over low-medium heat. You want the onion to be soft and translucent and the mushroom cooked down a bit.

Turn off the heat and mix in black olives, spaghetti squash, salt, and pepper. Stir in marinara until well combined.

Transfer mixture to a 9x13-inch casserole dish, top with vegan shredded cheese, and any additional toppings.

Reduce the oven temperature to 375F. Bake for 25 minutes or until heated through and cheese has melted. Remove from oven and let cool slightly. Serve and enjoy!

Tips & Tricks (5)

Drain Spaghetti Squash Thoroughly 💧
After roasting and shredding, place squash in a fine-mesh strainer and press gently for 5-10 minutes to remove excess moisture, preventing a watery casserole and ensuring better texture.
Sauté Vegetables First 🍄
Pre-cook mushrooms and onions for 3-4 minutes to release their moisture and concentrate flavors, creating a richer, more developed taste in your final dish.
Layer Strategically for Even Cooking 🔄
Alternate layers of squash, marinara, vegetables, and cheese rather than mixing everything together to ensure even heat distribution and better flavor in each bite.
Use High-Quality Vegan Cheese 🧀
Choose a vegan cheese blend that melts well (look for ones with tapioca starch) and add half before baking and half in the last 5 minutes for optimal melting and browning.
Rest Before Serving ⏱️
Let the casserole cool for 5-10 minutes after baking before serving to allow it to set properly, making it easier to portion and preventing the filling from being too loose.
