FAQ spaghetti squash:

Why is spaghetti squash called spaghetti squash?

It definitely has a unique name, but there’s a reason for it. This is because once it’s cooked, it literally comes apart and resembles spaghetti. It’s long and stringy (but tender) and is one of the main foods that people use to replace noodles or other foods that are high in carbs.

What does spaghetti squash taste like?

It’s a tad bit sweet, but not like acorn squash or sweet potato. It becomes very tender once cooked long enough and I find that it doesn’t really have an overly big taste of anything. This is why it’s such a versatile food.

How do you know when the squash is cooked?

If it’s whole, you’ll know it’s done by using a fork or sharp knife and poking it. If it’s tender, it’s done. If you’ve already cut it in half, the easiest way to see if it’s done is to take a fork and scrape at the inside of the squash a bit. If it’s tender and starts to pull away easily, that’s a big indicator that it’s ready to be pulled and served.

Ingredients for Baked Spaghetti Squash Recipe:

2 medium spaghetti squash, cut in half lengthwise and seeds removed
2 tablespoons olive oil, divided
1 teaspoon salt
½ teaspoon ground black pepper
1 small onion, peeled and diced
2 garlic cloves, peeled and minced
1-pound extra lean ground beef
24-ounce jar spaghetti sauce (lowest carb possible)
1 ½ cups shredded mozzarella cheese
¾ cup freshly grated parmesan cheese

Directions for Baked Spaghetti Squash:

Preheat the oven to 375F degrees.
Line a large baking sheet with foil. Use 1 tablespoon of the olive oil to brush the inside of each spaghetti squash half, then sprinkle with the salt and pepper. Turn the squash halves over, cut side down, onto the baking sheet.

Roast the spaghetti squash at 375F for 45 minutes until the squash is fork-tender.
As the spaghetti squash is baking, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and sauté until softened. Add the minced garlic and sauté for 1 minute.

Crumble the ground beef into the pan and cook until fully browned, then drain off any excess fat.
Reserve 1 cup of the spaghetti sauce and set aside. Next, add the remaining spaghetti sauce to the ground beef mixture; cover and simmer on low for 10 minutes.

After the squash is finished baking, carefully turn them over with a spatula and use a fork to fluff up the “spaghetti” in each shell. Add ¼ cup of the spaghetti sauce to each half of the squash and stir into the squash with a fork.

Sprinkle each squash half with the freshly grated parmesan cheese, then scoop the meat sauce onto each spaghetti squash half, then top with the shredded mozzarella cheese.
You will bake the stuffed squash spaghetti bowls at 375F for 15 minutes, or until the cheese is melted.

Cool the squash halves slightly, then serve hot.
