30-Minute Vegetarian Spaghetti Squash Boats

These Vegetarian Spaghetti Squash Boats are super healthy and ready in just 30 minutes. Filled with a vegan bolognese sauce and topped with vegan cheese!

I was recently interviewed for a Podcast and one of the food-related questions was, “What is your favorite cuisine?”

Hands down, my answer is and always will be: Italian food.

Give me a big bowl of pasta with a chunky tomato sauce and some fresh basil and I’m a happy camper. There’s nothing more comforting to me than a simple, tomato-based dish.

But in all honesty, sometimes I’m just not feeling a super carb-heavy and grain-heavy meal. I find if I have too many dinners like that I feel weighed down, bloated and puffy.

Which is precisely why I am so pumped it’s spaghetti squash season!

What’s great about spaghetti squash, aside from the fact it’s a wonderful grain-free pasta alternative, is that it’s actually quite simple to make. All you have to do is slice it in half and bake it for about 20 minutes and you’re done!

In fact, these vegetarian spaghetti squash boats take just 30 minutes to make, is packed with protein and is SO cozy!

the BEST canned tomatoes are definitely Tuttorosso Tomatoes!

Just like with most incredible Italian pasta recipes, the real secret to this heart-warming dish is the sauce.

I’ve made riffs on this red lentil bolognese before, but the main difference here is the tomatoes.

I’m sure you’ve heard me talk about Tuttorosso Tomatoes before, and I’m so excited to be partnering with them again in today’s post because their tomatoes are hands down the BEST canned tomatoes I’ve ever tasted. Not only do they actually look like tomatoes when you open the can (unlike others that are a soggy, soupy mess), but I’ve actually seen first-hand how they are packed and shipped.

Their tomatoes are family farmed, have no additives, preservatives, colors or flavorings, they are all non-GMO, and their cans are 100% recycled with non-BPA linings.

And guess what? The flavor is like they were picked right off the vine! (<– because they actually are!)

the BEST canned tomatoes are definitely Tuttorosso Tomatoes!

We are using Tuttorosso’s diced tomatoes with basil, oregano and garlic in this recipe because the consistency makes for the absolute perfect chunky tomato sauce.

We just add the tomatoes, lentils, some hummus, herbs, nutritional yeast and water into a pan, and let it bubble on the stove while the squash is roasting.

Once the squash is done, scoop out the seeds, flip it over, fill them with sauce, sprinkle with some (vegan) cheese, bake for another 5 mins and bingo.

Dinner on the table in under 30 minutes!

Preheat the oven to 425ºF. Cut the squash in half, lengthwise and put them face down in a baking dish. Add enough water to cover the squash by 1/4″. Roast squash for 20 minutes.

While the squash is cooking, add the remaining ingredients (minus the cheese) into a saucepan. Start with just 1/2 cup of water and add more as needed. Bring the pot to boil, then reduce and simmer until thickened, about 10 – 15 minutes. 

Once squash is done roasting, remove from oven, flip over and scoop out the seeds. Fill each squash half with about 1 cup of sauce. Sprinkle with cheese.

Place the squash back into the oven and turn the oven to broil. Broil for 2 – 3 minutes, watching carefully so the cheese doesn’t burn.

Remove and serve immediately!
