What are the best ways to cook spaghetti squash?

I find that there are 3 ways to cook spaghetti squash fast: using the microwave, the oven and the instant pot!

You can also just cut the spaghetti squash in half (creating 2 boats), scooping out the seeds and placing it in a 400F oven for 45-50 minutes.

How do you make the creamy green chili sauce?

The creamy green chili sauce is made from:

Soaked Cashews
Water
Canned green chili
Lime juice
Cilantro
Garlic powder
Salt

Simply combine the ingredients in a high speed blender until smooth. Store in the fridge for up to 5 days.

How to soak cashews for blending

You want to use soaked cashews so they are soft and easy to blend. There are 3 super simple ways to soak cashews:

Simply add fresh, filtered water to a bowl of cashews and allow it to sit out at room temperature for about 8 hours. Drain the water before using the cashews.
Bring water to a boil, add the cashews and allow to boil 2-3 minutes. Drain the water before using the cashews.
Add water and cashews to a microwave safe container. Microwave on high for 2-3 minutes. Drain the water before using the cashews.

Instructions:

Step 1: Cut the spaghetti squash and remove the seeds (see the tip above on how to make spaghetti squash easier to cut).

Step 2: Cook the spaghetti squash. You can roast it in the oven or follow these super simple tips on how to make spaghetti squash fast in the oven, microwave or Instant Pot.

Step 3: While the spaghetti squash bakes, make the creamy green chili sauce. Combine all the ingredients for the sauce in a high speed blender until smooth (takes about 1 minute to blend).

Step 4: While the spaghetti squash is cooking, start a cast iron skillet over medium to medium high heat. Add frozen peppers and cook through, which will take about 7-10 minutes. You want the liquid from the peppers to cook off. Turn off the heat once done cooking.

Step 5: Carefully scrape out the spaghetti strands from the squash. You will want to allow the squash to cool slightly.

Tip: If you are worried about your spaghetti squash bake getting soggy, add the spaghetti squash strands to a colander and gently press the squash with a wooden spoon to help remove excess liquid.

FAQ’s

How long does this recipe last in the fridge?

This recipe can be stored in the fridge for 5 days in an airtight container. Simply reheat in the oven, on the stove or in the microwave.

Can you freeze this recipe?

This recipe can be made in advance and frozen, however because of how squash defrosts, it will likely be watery and less enjoyable, so I would instead freeze the spaghetti squash and make the rest of the dish fresh.

You can freeze cooked spaghetti squash for later use. Simply cook the squash, scrape out the strands and store in a freezer safe container. You may want to undercook the spaghetti squash slightly so when you are defrosting it, it doesn’t get mushy. Be sure to use the tip about pressing out excess water once defrosted!

Substitutions:

Cashews: If you cannot have cashews or do not have them on hand, you can also use hemp hearts. You do not need to soak hemp hearts ahead of time.
Spaghetti squash: If you do not have spaghetti squash on hand, you can also make thinly cut butternut squash noodles. Simply spiralize the butternut squash and cook in the oven for about 12 minutes at 400F.
Canned green chilis: you can also make your own roasted green chilis, however, I rarely have the time for this! There are some great recipes on how to make your own roasted green chilis!
Cilantro: If you don’t love cilantro, simply leave it out of the recipe.
