    Now you have all the ingredients available, so start preparing your meal step by step from the instructions given below. You will surely enjoy this journey because this recipe will not make you tired or bored. It is just so much fun!

    Step 1 – Bake the Spaghetti Squash First

    Firstly, preheat your oven to 400 F, slice the squash into two pieces, take a spoon and take out all the seeds.

    Once it is softened, separate the squash in a bowl, add ½ tablespoon olive oil, and squeeze the salt and pepper according to your preference. 

    Prepare a baking sheet along with cooking spray and foil. Place the squash carefully in the oven and let it bake for 25 minutes. 

    When the squash is baking, please wait for it to cool down. Then scratch it out with a fork and place it in a bowl or plate. 

    Questions that may arise regarding this vegetable spaghetti:

    How to soften spaghetti squash?

    If the squash is hard, then let me tell you it is very easy to make it soft. Just microwave it for 4-5 minutes so it becomes cookable in the oven.

    Does spaghetti squash need to be refrigerated?

    Yes, you can store it in a dry and cool place, like a fridge, for about a month or two because it will be devastated if you keep it outside the dark and cool spot for a long time. 

    Step 2 – Prepare the Sauce

    To save time:

    • Starting making the sauce while baking the spaghetti squash takes time.
    • Take a pan and put it on medium-high heat.
    • Add two tablespoons of olive oil.
    • Add the chopped onions and minced garlic; cook them for about 5-10 minutes. 

    Add crushed tomatoes, Italian seasonings, red pepper flakes, and salt and pepper, according to your preference. Stir them for approximately 10 minutes and keep checking until it gets thick in texture.

    Note: if you like less thickness in sauce, add a small amount of water to make the sauce liquid. 

    But make sure you only add a little water so the sauce can be set on lasagna fillings and the top. 

    Well, the thick the sauce, the more creamy and delicious it will be. Not only taste, but it will also make your dish look pleasing and mouth-watering.

    Step 3 – Mixture of Ricotta Cheese with Squash

    You are almost there! Take out the baked spaghetti squash in a bowl and add 1 cup of ricotta cheese along with a pinch of salt and pepper, ½ cup of shredded mozzarella cheese, and sprinkles of spinach. 

    Mix these ingredients well, remove any excess you notice, and place the mixture in another bowl. Keep in mind that everything is well stirred, so you do not feel any inconvenience in the other-making process. 

    Step 4 – Place the Lasagna in Baking Dish

    Before setting up all the ingredients in the dish, preheat the oven to 375 F. Now take hold of a baking dish of about 8 x 11 inches and layer each component of the lasagna you made. 

    Firstly, spread out the sauce you made, then apply the half mixture of ricotta and spaghetti squash. Again, use the sauce as the second layer starts making its place with sauce, ricotta, and squash mixture. 

    After setting up the three layers, add the remaining sauce with the sprinkles of mozzarella cheese (the favorite part of lasagna for everyone).

    Step 5 – It’s Time to Bake, Serve and Enjoy!

    Once your baking dish is ready, place it into the oven and bake for 30-35 minutes until it boils well. Also, keep checking after every few minutes, so you do not burn your dish or something. 

    When the lasagna is cooked well, let it cool for a few minutes and garnish it with sprinkles of spinach or basil (you can also add any seasoning if you are a spicy food lover). 

    That’s a wrap! You are all set to serve spaghetti squash lasagna with drinks or salads, whatever you want. This delicious lasagna itself is enough when you are starving so badly.
