Ingredients for Tomato Feta Baked Spaghetti Squash

Gathering the right ingredients is the first step to creating this delightful dish. Here’s what you’ll need:

  • Spaghetti Squash: This is the star of the show! It’s a low-carb alternative to pasta, with a mild flavor that pairs beautifully with the filling.
  • Grape Tomatoes: These little gems add sweetness and juiciness. You can also use cherry tomatoes if that’s what you have on hand.
  • Baby Bella Mushrooms: Their earthy flavor enhances the dish. Feel free to swap them for any mushrooms you prefer, like button or portobello.

How to Make Tomato Feta Baked Spaghetti Squash

Step 1: Preheat the Oven

First things first, preheat your oven to 400°F (200°C). Preheating is crucial because it ensures even cooking. You want that perfect golden-brown finish on your veggies and feta. Trust me, it makes a world of difference in flavor and texture!

Step 2: Prepare the Spaghetti Squash

Now, let’s tackle the spaghetti squash. Carefully cut it in half lengthwise using a sharp knife. Be cautious—squash can be tough! Scoop out the seeds with a spoon, creating a hollow space for the filling. This step is essential for achieving that delightful spaghetti-like texture later on.

Step 3: Mix the Filling

In a large bowl, combine the grape tomatoes, baby bella mushrooms, fresh basil, and garlic. Drizzle in the olive oil, then sprinkle with salt and black pepper. Mix everything well, allowing the flavors to meld together. The vibrant colors and aromas will have your mouth watering in anticipation!

Step 4: Fill the Squash

Next, it’s time to fill those squash halves! Spoon the tomato mixture generously into each half, making sure to pack it in. Crumble the feta cheese on top, letting it nestle into the filling. This is where the magic happens, as the feta melts and mingles with the veggies during baking.

Step 5: Bake the Dish

Place the filled squash halves on a baking sheet and pop them into the oven. Bake for 40-50 minutes, or until the squash is tender. To check for doneness, poke it with a fork; it should easily pierce through. Your kitchen will smell heavenly!

Step 6: Serve and Enjoy

Once baked, remove the squash from the oven. Use a fork to scrape the flesh into strands, mixing it with the filling. Serve warm, and enjoy this delicious Tomato Feta Baked Spaghetti Squash. It’s a dish that’s sure to impress!
