My Go-To Spaghetti Squash “Pasta” Bake
This is, in all seriousness, one of my favorite go-to weeknight dinners. This dish layers tender squash threads with seasoned ground beef, arrabbiata sauce, and melted mozzarella for a high-protein, veggie-forward dinner. Image: Liza Graves
I’m always looking for ways to add more vegetables to my meals. I am truly one of those people that the more vegetables I eat, the better I feel, as a rule. This spaghetti squash bake checks all those boxes — and it’s become one of my favorite weeknight dinners.
I’m also gluten-free (unfortunately, I have been for 20 years!). But even if I weren’t, I would still love this dish, as you can eat a lot of it without the heavy feeling that pasta can leave you with.
When it comes to spaghetti squash, they used to dry up on my counter before I would cook them. Why? I’m terrified of them. Those things are rock-hard, and I’ve come too close to losing a finger too many times (if even in my mind). So instead, I’ve learned to cook spaghetti squash whole. The trick is to poke about 20 small slits into the skin with a paring knife before it goes in the oven. If you skip this step, you risk a squash-explosion situation.
Trust me. Make those slits!

Pop that squash in a 400-degree oven for an hour. The beauty of this approach? You can come home from work, pick the kids up from school, toss it in the oven, and go about your evening. No biggie.
After an hour, take it out and let it sit for 15 minutes, then slice it open. The seeds scoop out easily when the squash is cooked.
Then, use a fork to pull out those beautiful squash threads. Place them in a large, shallow, oven-safe bowl and season with seasoning salt (I’m partial to Lawry’s) and black pepper.
While the squash is cooling, brown some ground beef and warm up your favorite arrabbiata sauce. I use Rao’s because it’s got great flavor without any weird ingredients. Layer the sauce over the squash, add the ground beef, and top with mozzarella — fresh or shredded, your choice.
Back in the oven it goes for five to 10 minutes, just until the cheese melts and starts to brown.
The final touch? Chopped Castelvetrano olives and green onions. The olives add this briny, buttery flavor that cuts through the richness, and the green onions give it freshness.
It’so delicious, you’ll never miss the pasta.
