Step 1

Pre-heat oven to 400 degrees F.

Step 2

Slice your spaghetti squash in half lengthwise and scoop out the seeds.

Step 3

For easy cutting, feel free to microwave for 4-5 minutes to soften it up just a tad. The knife slides through much easier this way!

Step 4

Next grab a lipped baking sheet or a rimmed baking dish.

Step 5

Rub the cut side of the squash with a teeny bit of olive oil.

Step 6

Place inside a baking dish or atop rimmed baking sheet and roast face-down for about 40 minutes, or until tender and easily pierced with a fork.

Step 7

Cooking time will vary a bit depending on the size of your squash so adjust accordingly. Once ready, the once rock-hard exterior of the squash will be visibly softened with a tender interior.

Step 8

While the squash roasts, start prepping your cheese and veggies.

Step 9

Chop your onion, garlic, mushrooms, spinach and tomato, separately, then set aside.

Step 10

Bring a pan or skillet to medium-high heat with a drizzle of olive oil.

Step 11

Sauté onion until tender and slightly golden, then add garlic and mushrooms and continue to cook until softened. Set aside.

Step 12

In a large bowl, combine ricotta, egg white, freshly grated parmesan cheese, fresh chopped spinach, Italian seasoning, basil, and garlic powder.

Step 13

Drain your mushroom/onion mixture and add to the bowl along with your chopped tomato.

Step 14

Mix well, adding a little salt and pepper to taste.

Step 15

Once your squash is ready, allow to cool slightly, then use a fork to separate the squash's interior into spaghetti-like strands.

Step 16

Remove a little of the squash will help you better stuff these bad boys.

Step 17

Take a little out and add your filling to the squash, swirling to mix.

Step 18

Top with remaining spaghetti squash strands and stir.

Step 19

Next add a few spoonfuls of your favorite spaghetti sauce on top and finish off with your grated mozzarella cheese. Add extra of either if desired.

Step 20

Add an optional pinch of crushed red pepper flakes on top (skip if sensitive to heat) and bake at 350 degrees F for around 20 minutes until hot and bubbly.

Step 21

For golden flecks of mozzarella, switch oven to broil on HIGH for 2 minutes at the end and remove once bubbling.

Step 22

Serve piping hot with a healthy side salad or roasted veggies for a balanced meal that's sure to rock your plate! Enjoy!
