Spaghetti squash is just begging to be used as its namesake, isn't it? That's why this Paleo Spaghetti Squash & Meatball Casserole Recipe needs to get made, stat.

If you can't imagine spaghetti without plump meatballs nestled among the strands, you probably immediately thought of spaghetti and meatballs when you first heard of spaghetti squash. (Me, too). I quickly learned that spaghetti squash isn't literally a squash that tastes like spaghetti and meatballs, and it's much more versatile than that. (See, for example, spaghetti squash chow mein).

Still, this simple gluten free recipe has been a long time comin', and I'm glad it's finally ready to share on the DoYouEvenPaleo!

Legit conversation that happened with my spouse the first time I made this spaghetti squash & meatball casserole:

Him: "I'm surprised you're eating this!"

Me: "Why? It's good."

Him: "But you haven't eaten pasta in... years."

Me: "... This isn't pasta."

Him: "What? No way. What is it, then?"

Apparently my husband didn't really get spaghetti squash until that night. But, nonetheless, he adored this casserole even though he's a squash hater.

Isn't it a little weird that spaghetti squash is the only squash that gourd-haters seem to like? Meanwhile, I'd rather be inhaling a feast of roasted kabocha squash. Awwww yeah.

Not to say I don't like spaghetti squash. I just don't bother with it most of the time.

But when you're prepping meatballs and the thought for a big, hearty, cook-once-and-eat-for-the-week casserole pops into your head, you've got to pursue that shit.

Frankly. casseroles are my favorite use for spaghetti squash. The stringy gourd makes an excellent base for all types of combinations, like Chicken Bacon Ranch. Unlike other squashes, spaghetti squash is pretty neutral, so the other add-ins impart the flavor.

Moving on. Let's talk about the sauce. One recurring theme of this blog is no bland food. I made this casserole a number of times, tweaking the sauce and meatballs until I hit on the right amount of spice. Because seriously, spaghetti sauce shouldn't taste like tomato sauce. You've got to have notes of basil, oregano, and parsley. Ah, now that's a good marinara!

Instructions

Preheat the oven to 400 degrees F.
Carefully cut the spaghetti squash in half lengthwise. Remove the seeds. Place the squash cut side down on a rimmed baking sheet. Cook for 45 minutes or until squash is tender. Use a fork to separate out the spaghetti squash strands from the peel. Let cool enough to handle. Measure out 8 cups spaghetti squash for the recipe (give or take - a little more or a little less won't hurt anyone).
Reduce the oven to 350 degrees F.
Heat the olive oil in a skillet over medium heat. Add the onion and garlic, sautéing for about 5 minutes or until onion has softened and turned translucent. Remove from heat.
In a large bowl, mix cooked spaghetti squash, sautéed onion and garlic, tomato sauce, tomato paste, basil, parsley, oregano, salt, and pepper until the spaghetti squash is coated evenly.. Place in a large 9x13 casserole dish.
In a separate medium bowl, mix the meatball ingredients - be careful not to over-mix, or the meatballs will turn out tough! Form meatballs and arrange in rows across spaghetti squash and sauce mixture. Bake for 40 minutes or until meatballs are cooked through. Garnish the finished casserole with some fresh parsley, if desired. This casserole will keep in a tightly sealed container in the fridge for up to a week. Serve warm.
