How to Make Mexican Spaghetti Squash Casserole

Now that you have all your ingredients ready, let’s dive into making this delicious Mexican Spaghetti Squash Casserole. Follow these simple steps, and you’ll have a hearty meal that’s sure to impress!

Step 1: Preheat the Oven

First things first, preheat your oven to 350°F (175°C). Preheating is crucial because it ensures even cooking. You want that cheese to melt perfectly and the casserole to bake just right!

Step 2: Prepare the Spaghetti Squash

Next, grab your spaghetti squash. Cut it in half lengthwise and scoop out the seeds. Place the halves cut-side down on a baking sheet. Bake for about 30-40 minutes until tender. The goal is to achieve a soft texture that easily pulls into strands.

Step 3: Cook the Ground Turkey

While the squash is baking, heat a skillet over medium heat. Add the ground turkey and cook until it’s browned. Make sure to break it apart with a spatula. This step is key for flavor, so don’t rush it! You want that turkey to be nicely browned.

Step 4: Combine the Ingredients

Once the turkey is cooked, it’s time to add the chopped bell peppers, corn, black beans, green chiles, diced tomatoes, enchilada sauce, chili powder, cumin, and salt. Stir everything together and let it cook for a few minutes. This is where the magic happens, and your kitchen will start to smell amazing!

Step 5: Add the Spaghetti Squash

Now, take your baked spaghetti squash and scrape out the strands with a fork. Add these strands to the skillet mixture. Gently fold everything together, ensuring the squash is well incorporated. This is the heart of your low-carb Mexican spaghetti squash casserole!

Step 6: Mix in the Eggs

In a separate bowl, beat the eggs and then mix them into the casserole mixture. The eggs act as a binder, helping to hold everything together. This step is essential for achieving that perfect casserole texture!

Step 7: Transfer and Top with Cheese

Transfer the mixture to a greased baking dish. Spread it out evenly, and then sprinkle your cheese on top. I love a generous layer of cheese because it adds that gooey, melty goodness we all crave!

Step 8: Bake to Perfection

Finally, pop the casserole in the oven and bake for 25-30 minutes. You’ll know it’s done when the cheese is melted and bubbly. Let it cool for a few minutes before serving. Trust me, the wait will be worth it!

Tips for Success

• Use a sharp knife to cut the spaghetti squash; it makes the process easier.
• Don’t skip the rinsing step for black beans; it helps reduce sodium.
• Feel free to customize with your favorite veggies or proteins for a personal touch.
• Let the casserole cool slightly before serving; it helps it set up nicely.
• Store leftovers in an airtight container for up to 4 days.

Equipment Needed

• Baking Sheet: A standard sheet works, but a rimmed one prevents spills.
• Skillet: A non-stick skillet is great for browning turkey without sticking.
• Baking Dish: Any oven-safe dish will do; glass or ceramic is ideal.
• Fork: Use it to scrape the spaghetti squash into strands.
• Mixing Bowls: A couple of bowls for mixing ingredients and eggs.

Variations To Try

• Vegetarian Delight: Swap the ground turkey for extra beans or lentils for a hearty vegetarian option.
• Spicy Kick: Add diced jalapeños or use hot enchilada sauce for a spicier version of this casserole.
• Cheesy Goodness: Experiment with different cheeses like pepper jack or cheddar for a unique flavor twist.
• Herb Infusion: Toss in fresh cilantro or parsley before serving for a burst of freshness.
• Southwestern Style: Incorporate corn salsa or roasted corn for an extra layer of flavor.

Serving Suggestions

• Pair with a fresh green salad for a light and refreshing contrast.
• Serve with tortilla chips and guacamole for a fun, Tex-Mex twist.
• A dollop of sour cream or Greek yogurt on top adds creaminess.
• Enjoy with a chilled glass of iced tea or a fruity mocktail.
