TikTok Feta Pasta Who?

Remember that TikTok feta pasta that broke the internet?! If you haven't made it, stop what you are doing and give it a try because it's absolutely DELISH! I loved it so much that I decided to create a lighter, more macro-friendly version.

Introducing this perfectly tasty Baked Feta Spaghetti Squash. It's just like the viral recipe, but it packs way more volume and flavor, in my humble opinion. Instead of pasta noodles, I roasted and shredded a spaghetti squash for a low-carb swap. I also mixed in some delicious pesto sauce and fresh herbs to add some more cheesy, savory flavor.

And it's still perfectly creamy thanks to some delicious and melty feta cheese! What more could you ask for?

Trust me—one bite of this Baked Feta Spaghetti Squash casserole will completely satisfy your comfort food cravings and have you also going back for seconds.

Spaghetti Squash Feta Cheese Casserole Ingredients

Cooking Spray: This is important to use so our ingredients don't stick to our dishes.

Everything But The Bagel Seasoning: In my opinion, this is one of Trader Joe's BEST seasonings! It literally tastes just like an everything bagel. And it brings unreal flavor to this dish.

Spaghetti Squash: This is the big yellow squash you'll find at the grocery store. I used a medium-sized one.

Garlic: I used minced garlic for convenience, but you can chop up some cloves if you'd like.

Ground Turkey: I used 99% lean ground turkey.

Onion: I used a white onion for sweetness.

Italian Seasoning: Such yummy, hearty flavor!

Spinach: We'll be chopping this up real small so we get a little bit in each bite.

Feta Cheese: Has the best flavor. One of my favorite cheeses. I used an 8oz block.

Tomatoes: I used cherry tomatoes, but if there is a tomato you like better, feel free to use that.

Thyme and Basil: I used about 4 stalks of each.

Knorr Pesto Seasoning Packet: I love using these packets for a super convenient way to add more flavor. Just prepare according to package instructions!

Mozzarella Cheese: I used fat-free, shredded mozzarella.

The kitchen equipment you'll need for this Spaghetti Squash Feta Cheese Casserole Recipe

To make this Spaghetti Squash Feta Cheese Casserole recipe, you'll need a skillet, small saucepan, casserole dish, cutting board, chef’s knife, mixing spoon, measuring cups + spoons, baking sheet, strainer, rubber spatula, and parchment paper.

How to make this Spaghetti Squash Feta Cheese Casserole Recipe

1. Preheat your oven to 400°F.
2. Cut your spaghetti squash in half and use a spoon to remove the seeds from the center. Spray the squash with cooking spray or brush with olive oil. Then, sprinkle with Everything but the Bagel seasoning and place face down on a baking sheet.
3. Bake for 25-30 minutes or until the squash can be shredded with a fork.
4. While the squash is baking, grease a casserole dish. Then, place the block of feta cheese, fresh herbs, sliced cherry tomatoes, and diced onion in the dish.
5. Place casserole dish in the oven on the same rack as the squash and bake for 30 minutes.
6. Next, let's start preparing the ground turkey. Heat a skillet to medium-heat and spray with cooking oil. Then, add the ground turkey, minced garlic, and Italian seasoning. Cook until the meat is done.
7. Grab a small sauce pot. Add the Knorr Pesto Seasoning packet and cook according to instructions on the bag. NOTE: If you want to make this more macro-friendly, spray cooking spray into the pesto instead of using olive oil. You’ll have to spray a decent amount, but I’ve done it before and it works.
8. Once the spaghetti squash, feta, and vegetables are done baking, remove from the oven. Shred the spaghetti squash with two forks and place into the casserole dish with the baked feta and vegetables.
9. Fold in chopped spinach immediately. The heat from the other ingredients will make the spinach wilt just like we want.
10. Then, stir in the cooked ground turkey. Add the pesto sauce and keep stirring. 
11. Top the casserole with mozzarella cheese. Broil at 500°F for 3-5 minutes or until cheese starts to bubble/brown.
12. Serve hot or put into meal prep containers for the week!

questions and answers

How should I store this Spaghetti Squash Feta Cheese Casserole?
Store it in the refrigerator in an airtight container for up to 5 days.

Is this good for meal prep?
Yes! It's actually one of my favorite meal prep recipes. Just portion out into your containers and grab & go as needed. Makes a great lunch or dinner!

Is it possible to speed up the cooking process?
If you have a pressure cooker, you can use it to cook your spaghetti squash a little faster. Slice the squash in half, scoop out the seeds, and cook on high for 3 minutes. Then, manually release the pressure. You can do this while your oven preheats for the final bake to save some time.

Can I make this without meat?
Of course! All you would have to do is omit it.

What other protein could I use in this Spaghetti Squash Feta Cheese Casserole recipe?
I recommend ground or grilled chicken. A salmon filet would go great with the flavors in this recipe. If you take the salmon route, however, cook the fish separately.

What other cheese can I use besides feta cheese?
I think goat cheese, ricotta, or chevre would be delicious and keep this recipe nice and creamy. If you’re dairy free, vegan feta would also work. I've seen it done in many of the vegan remakes of the famous TikTok pasta. Note if you do use vegan feta, it's likely going to be more crumbly than melty.
