Cheesy Spaghetti Squash With Meat Sauce

Share to...

Baked spaghetti squash is one of my favourite Fall recipes to make, and they are inexpensive to purchase.

Spaghetti squash, when cooked, looks like spaghetti once you fork it out, but it’s not.

The cooked squash has a buttery subtle taste that melts in your mouth and is perfect as a side dish.

My recipe is also a keto spaghetti squash menu item for those who want to try it.

We buy a double pack of spaghetti squash at Costco Canada for $4.99 at least twice during the season.

Today, I’m going to share how to bake spaghetti squash so it doesn’t go mushy. (I know from experience)

Then, I’m going to stuff the baked spaghetti squash with an Italian homemade meat sauce.

Finally, I will top it with two of the best Italian cheeses and broil it until it’s bubbly and golden.

Now that I have you drooling, let me show you how it’s done.

What Is Spaghetti Squash

Spaghetti squash or vegetable spaghetti is a group of cultivars of Cucurbita pepo subsp. pepo.

They are available in a variety of shapes, sizes, and colours, including ivory, yellow and orange, with orange having the highest amount of carotene. Its center contains many large seeds.

For many people, squash looks like one of those vegetables that look too difficult to use.

To cook spaghetti squash, you need a few kitchen tools and 2 ingredients.

We both love pasta, so instead of loading up on carbs, we thought we’d bake a spaghetti squash.

The first time we baked it in the oven, it turned out to be too mushy because we baked it too long.

We found that the squash was the consistency of a mashed yam or potatoes but still delicious.

Since every spaghetti squash is different in size, it will bake at different times.

Generally, we find 40 minutes at 350 degrees will do the trick for us, and we have an old wonky oven.

By that, I mean if any recipe calls for the oven temp to be at 400 degrees or above, it stays at 350.

We’ve set the fire alarms off every time baking something at 400 degrees, so that’s a big NO.

Personally, I think our stove has done its time over the years and is ready to move on.

Preheat your oven to 350 degrees.

On a cutting board, cut the squash length-wise and split it open.

Inside you’ll find seeds that look like pumpkin seeds which you can roast and taste delicious.

These are pumpkin seeds getting ready to bake. You can bake spaghetti squash seeds also.

Scoop out all of the seeds, give the squash a run under cold water, and let it drip dry for a minute.

Using a liberal amount of butter, baste the inside of each squash add salt and pepper.

Flip the squash over so the butter side is down on a parchment-lined baking sheet or roasting pan.

We bake our squash for 40 minutes at 350 degrees, and it’s perfect once I do my testing.

I test it once during the cooking process, and if I can stick a fork through the squash, it’s done.

If you’re unsure about your oven temp or toaster oven, check on it at the 30-minute mark.

I wouldn’t go over 40 minutes baking the squash because you don’t want to mush it.

When you use a fork, you should be able to pull strands of squash out like it was a bowl of pasta.

Now it’s time for the sauce.

How To Make Italian Bolognese Sauce

I’ve made bolognese sauce on the blog before, and it’s simple to make ahead of time.

That’s what we do as it cuts down on the process, especially if it’s a work night or the kids have sports.

Ingredients NeededClick the link above for the full recipe.

Note: We had two leftover BBQ Italian sausages, so I cut them up and added them to the sauce.

Whatever sauce we had left, I turned that into a keto chilli the next day.

  • 1lb Ground Beef and 1lb Ground Pork
  • 1/4 cup extra-virgin olive oil
  • 2 bay leaves
  • 2 teaspoons sea salt
  • 1 teaspoon fresh black pepper
  • 4 cups of whole tomatoes Run through a mill or crushed (San Marzano is the best and you can find them at Costco Canada.}
  • 1/2 cup dry red wine (any will do) eliminate this if you are KETO
  • 2 Tablespoons Tomato Paste
  • 1/2 cup of Chicken Stock Broth
  • 3/4 cup chopped celery
  • 1 carrot chopped fine 1/2 cup
  • 1/2 clove of minced garlic
  • 1 medium diced white onion 3/4 cup

Types Of Italian Cheeses We Buy

Two of the best Italian cheeses you can buy are Saputo mozzarella and Parmigiano Reggiano.

If you’re ambitious, you can make mozzarella at home, although I’ve never tried it before.

Another great cheese is Grana Padano and Romano cheese which is a bit salty but delicious.

Differences Between Grana Padano And Parmigiano Reggiano Cheese

The Grana Padano cheese is less expensive than the Reggiano and a great alternative.

Costco Canada sells all three, or you can find it a local grocery stores, cheese companies or an Italian grocer.

Grana is softer, butterier and it tastes slightly more delicate. Cheese experts can even taste smells of broth or steamed vegetables.

Parmigiano generally has a more decisive flavor and the longer it maturates, the more the aromatic notes become recognizable.

You’ll never find me wasting money on canned grated cheese or pre-grated cheeses in plastic containers.

Just don’t do it.

Buy it fresh in a chunk and grate it yourself because a little goes a long way, and the taste is amazing.

Save up for a blog which generally costs about $23 or less when on sale at Costco.

You can buy smaller pieces at Zehrs, which we’ve purchased found in the cheese bunkers by the deli.
