Vegetarian Spaghetti Squash Lasagna l SimplyScratch.com #meatlessmonday

I have a little meatless for your Monday.

It was about time that SS had a vegetarian lasagna. And since squash is in season, why not use spaghetti squash as the “pasta” and while we’re at it, layer it with a veggie loaded sauce! And of course, lasagna isn’t lasagna without allthecheese?

This lasagna is a recipe I developed for Simply Organic. I decided to omit the traditional ricotta layer because I wanted to keep it light. The end result being a fresh, flavorful lasagna spiced perfectly with rosemary, basil and oregano and did I mention this lasagna is actually good for you? Except maybe all the cheese… but it’s not like you’re going to peel off the top layer, fold it up and eat it like a sandwich.  Ha-um that would be crazy. Yeah, I mean who would do such a thing? ME. I did the thing. However the over abundance of veggies totally cancels the calories of the cheese, right?

squash prep

First prepare the spaghetti squash:

Start by trimming the ends off of the spaghetti squash. Cut it in half, remove the seeds and place cut-side-down in a large baking dish. Roast the squash halves in a 375° oven for about an hour or until a knife glides effortlessly when pierced. Keep your oven preheated at the same temp for the lasagna.

Then remove and let cool off until safe to touch. Use a fork and scrape the flesh of the squash to form the spaghetti strands.

To Make The Sauce You Will Need:

  • olive oil
  • butter
  • yellow onion, chopped
  • carrot, grated
  • zucchini, sliced into 1/4 inch thick half moons (about 1 1/2 cups)
  • yellow squash, sliced into 1/4 inch thick half moons (about 1 1/2 cups)
  • crimini mushrooms/baby portobellos (about 3 medium-sized)
  • fresh garlic, minced
  • 1-1/2 teaspoons rosemary
  • 1/2 teaspoon basil
  • 1/2 teaspoon oregano
  • 1 can (28 ounce) crushed tomatoes
  • 1/2 cup pinot noir
  • 1 teaspoon sugar
  • sea salt
  • freshly ground black pepper

add in onion and carrot

In a 10-inch pan, add 1 teaspoon olive oil and sauté a diced yellow onion (about 1 cup) and 1 medium carrot (that has been grated) together until they are soft.

add to a bowl and set aside

Once soft, transfer them to a clean plate and get going on the rest of the vegetables.

saute squash and zucchini

Increase the heat to medium-high adding more oil if needed. Add 1 medium zucchini and summer squash (that were halved and sliced) to the pan and sauté until golden and they are just starting to turn soft. Try not to stir too much so they can brown.

mushrooms

Turn the heat back down to medium and add in 1 cup finely chopped cremini mushrooms.

garlic

Cook for a minute or two before adding in 2 cloves minced fresh garlic and cook for 2 minutes.

To the skillet, add the sautéed onions and carrots back in along with the 1-1/2 teaspoons rosemary, 1/2 teaspoon both dried basil and oregano, 1 (28 ounce) can crushed tomatoes and 1/2 cup dry red wine. You can totally substitute broth for the wine!

simmer until thick

Lastly, season with 1/2 teaspoon sugar and kosher salt and black pepper to taste. Let the sauce simmer for 15-20 minutes until it has thickened slightly.

Smells heavenly.

Next, add half of the spaghetti squash and season with a pinch of salt and pepper.

cheese

Top with half of the sauce and sprinkle with 1/2 cup freshly grated mozzarella and 1/4 cup grated Parmesan.

ready to bake

Top that with the remaining spaghetti squash, sprinkle with a little more kosher salt and pepper and top with the remaining sauce and cheese. Since the sauce and squash are already cooked, you really only need to get the cheese melted and golden brown on top.

Slip the lasagna onto the middle rack of your preheated 375° oven and bake for 25 to 30 minutes.
