For the Casserole

• 2 large spaghetti squash
• 2 cups broccoli florets (150 g)
• 2 Tbsp olive oil (30 mL)
• 1 16-oz jar Alfredo sauce (about 1 ½ cups, 453 g)
• 1 cup shredded mozzarella cheese (divided, 100 g)

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

Step 1: Preheat the Oven

Preheat your oven to 400°F (204°C). This ensures that your casserole cooks evenly right from the start.

Step 2: Prepare Spaghetti Squash

1. Cut each spaghetti squash in half lengthwise.
2. Scoop out the seeds from each half.
3. Drizzle most of the olive oil inside each half and rub it to coat evenly.
4. Place cut-side down on a baking sheet.
5. Prick the outside with a fork to allow steam to escape.

Step 3: Add Broccoli

1. Spread broccoli florets onto the same baking sheet.
2. Drizzle with remaining olive oil, tossing to coat evenly.

Step 4: Roast

Roast in the preheated oven for about 30 minutes. Check until the squash is fork-tender but still slightly firm. The broccoli should be lightly browned; if it cooks faster, remove it early.

Step 5: Spaghettify

Once cooked, flip over each spaghetti squash half to cool enough to handle. Use a fork to scrape out strands from inside each half into a large bowl.

Step 6: Assemble

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 gently pack it into an even layer. Sprinkle remaining mozzarella cheese on top.

Step 7: Broil

Switch your oven to broil mode. Place your casserole dish under the broiler for just a few minutes—watch closely until the cheese melts and turns golden brown.
