Low Carb Mexican Spaghetti Squash Boats

I loved all the suggestions I got on my Easy Low Carb Mexican Casserole, and I have been on a bit of a Mexican binge lately. I’ve also been fascinated with all the different Spaghetti Squash boat recipes I see and share on the Zen Facebook Page – they tend to be well received.

I haven’t had a Spaghetti Squash in ages. When I tried to use them to sub as pasta, I just wasn’t impressed. Too much trouble for something that didn’t really have the texture or taste of pasta. But after reading some tips on preparing Spaghetti Squash, I thought I might give it another go. So when I saw some Spaghetti Squash in the grocery store, a little light bulb went off in my brain. “Why not combine the two?”

Hello Low Carb Mexican Spaghetti Squash Boats!

I was very happy with how my Low Carb Mexican Spaghetti Squash boats turned out! I hope you will like them, too.

  • 1 spaghetti squash (Cut in half)
  • 1 pound hamburger
  • 1 tablespoon liquid Smoke® (Optional)
  • 1 1/2 teaspoons Beef Base (Optional)
  • 1 tablespoon minced garlic
  • 1 tablespoon dried onion (flaked)
  • 1 onion powder
  • 1 1/2 tablespoons chili powder
  • 1 teaspoon cumin
  • 1 cup Monterey jack cheese (shredded)
  • 1/4 cup salsa (fresh)
  • 3 tablespoons sour cream


  • Preheat oven to 425 degrees
  • Cut the Spaghetti Squash in half and remove the seeds and pulp from the middle of the squash.

  • Place squash cut-side down on a cookie sheet covered in parchment paper or a silicone bake mat (for easier clean-up).

  • A few minutes after the squash gets started, put your hamburger in a skillet to get it going.
  • Add liquid smoke and beef base to hamburger if using.
  • This would be a great time to grate your cheese! (Pre-shredded cheese has more carbs from the stuff they add to keep it from sticking, and the freshly-grated does taste better anyway.)
  • Add minced garlic, the dried onion, the onion powder, your chili powder and cumin to cook with the hamburger.
  • Cook the squash about 35 minutes, until lightly browning and the squash strands easily separate from the outside of the squash with a fork. If you've timed it right, your hamburger should be getting brown about the time your squash is done. (Mine was in a little too long, because Martha Steward lied and said it would take an hour!)
  • Remove squash and reduce oven heat to about 325.
  • Use a fork to separate the stringy strands of your squash from the outer skin.

  • With the Hamburger skillet on medium heat, mix in those lovely Spaghetti squash strands and let them fry together for about 5 minutes to soak up the flavor of your spices.

  • Layer the hamburger mix and shredded cheese in the squash shells - mix first, then cheese, mix, cheese. You will have leftover hamburger mix!

  • Pop these back in the oven with the lower heat setting about another 10 minutes, letting the cheese get good and gooey.
  • I added about a tablespoon and a half of sour cream to each one and some fresh salsa on top.

Recipe Notes

I'd use ground beef at least 80% lean. When I made this recipe again using fattier ground beef, it was too greasy.

    • I counted it as 3 because there was a lot of leftover hamburger/squash mix! More than I could neatly stuff in the two halves. I used the leftovers as a side dish but they could feed somebody else in a bowl.

  • Been wanting to try taco sqaush when i use it as regular spaghetti I get sick to my stomach and cant eat hope this doesnt so it too

  • 5 stars
    Here is what I do. i cook my spaghetti squash in the microwave. Keep in whole, piece a few little holes in it with a fork or knife. Microwave for six minutes. Check, add time if needed. It will be soft to the touch. Let it cool, slice, and remove seeds. I usually do mine ahead if time since it’s so hot to handle. This is just my way, less dishes.
