How to Make Alfredo Spaghetti Squash Casserole (5 Ingredients!)

Step 1: Preheat the Oven

Preheat your oven to 400°F (204°C). This temperature is perfect for roasting vegetables and ensuring your casserole cooks evenly.

Step 2: Prepare the Spaghetti Squash

1. Cut each spaghetti squash in half lengthwise and scoop out the seeds.
2. Drizzle most of the olive oil inside each half.
3. Rub to coat evenly and place cut-side down on a baking sheet.
4. Prick the outer skin with a fork for even cooking.

Step 3: Roast the Veggies

1. Spread broccoli florets onto the same baking sheet.
2. Drizzle with remaining olive oil and toss to coat well.
3. Roast in the oven for about 30 minutes until squash is fork-tender but still firm, and broccoli is lightly browned.

Step 4: Spaghettify

Once roasted, flip the spaghetti squash halves over to cool slightly. Use a fork to scrape out strands from inside each squash half into a large bowl.

Step 5: Assemble Your Casserole

In your large bowl, combine spaghetti squash strands, roasted broccoli, Alfredo sauce, and ½ cup of mozzarella cheese. Pour this mixture into a large casserole dish and pack it gently into an even layer. Top with remaining mozzarella cheese.

Step 6: Broil to Perfection

Switch your oven setting to broil. Place the casserole dish under the broiler for just a few minutes. Watch closely until the cheese melts and turns golden brown for that perfect finish!

Common Mistakes to Avoid

Many people make simple mistakes when preparing Alfredo spaghetti squash casserole. Here are some common pitfalls to watch out for.

• Skipping the roasting step: Not roasting the spaghetti squash properly can lead to a mushy texture. Make sure to roast until fork-tender but firm to preserve the right consistency.
• Overcooking broccoli: If you cook the broccoli too long, it can become soggy. Add it to the oven later or check it early to ensure it’s perfectly roasted.
• Using the wrong size squash: Smaller spaghetti squashes may not provide enough strands. Choose large ones to ensure you have enough for a hearty casserole.
• Not measuring the sauce: Too much or too little Alfredo sauce can alter the flavor balance. Stick to about 1 ½ cups for optimal taste.
• Neglecting cheese distribution: Evenly distributing mozzarella helps create that delicious, gooey top layer. Sprinkle it evenly for best results.
