Excellent Gluten-Free Substitution For Traditional Pasta
It's been a long, long time since I've had traditional pasta, which I ate a lot of when my diet consisted of high-carbohydrate and high-processed foods.
Since I now eat gluten-free, I honestly thought I'd never be able to eat pasta again, until now.
Therefore, I was so excited when I came across this recipe from Lexi's Clean Kitchen.
It transforms a regular spaghetti bake recipe into a gluten-free version and I made a few changes to it to make it 100% vegan.
Can Be Meal-Prepped To Save Time
The most time-consuming part of this recipe is baking the spaghetti squash, which takes about 45-50 minutes.
Although it's "inactive time", it's still time waiting to get dinner on the table.
Another alternative is to make the spaghetti squash in advance, or meal prep it.
The rest of the recipe can be assembled in about 5 minutes, then you only need about 20 minutes to warm it in the oven before serving.
Made With Clean Ingredients
This recipe is made with 9 clean ingredients, such as spaghetti squash, avocado oil, organic pasta sauce, baby spinach, ground flax seeds, garlic, nutritional yeast, ground cayenne pepper, and Himalayan pink salt.
You can even garnish it with fresh chopped basil for an extra touch.
This healthy recipe is plant-based, vegan, gluten-free, dairy-free, soy-free, nut-free, egg-free, paleo-friendly, and can be Medical Medium® compliant with substitutions.
Frequently Asked Questions
How Can I Make This Recipe Medical Medium® Compliant?
There are two simple substitutions to keep in mind if you need this recipe to be 100% Medical Mediuim® compliant:
- Nutritional Yeast - This ingredient is not a compliant ingredient and would need to be eliminated. You could replace it with gluten-free breadcrumbs as a substitute.
- Marinara Pasta Sauce - You will need to make sure the pasta sauce is in a BPA-free container, has a minimal ingredient list, and does not contain citric acid.
Other than that, all other ingredients in the recipe are Medical Medium® compliant!
Karielyn's Expert Tips + Ingredient Substitutions
Spaghetti Squash: The sizes of spaghetti squash vary, but if you get a medium-large size it should be enough for 4 servings. If you don't like or can't find spaghetti squash, you could substitute it with gluten-free, grain-free, or corn-free pasta.
Avocado Oil: Can be substituted with organic extra-virgin olive oil.
Baby Spinach: While this gives the recipe extra nutritional value, it could be omitted if you prefer.
Marinara Pasta Sauce: As a time-saver, you can use a store-bought organic pasta sauce, but make sure it is in a BPA-free container, has a minimal ingredient list, and does not contain citric acid.
*Nutritional Yeast: This is added as a non-dairy replacement for Parmesan cheese. However, if you need the recipe to be 100% Medical Medium® compliant, it will need to be omitted.
Garlic: Freshly crushed garlic will give the best flavor and nutrients, but you could substitute it with organic garlic powder - just adjust the amount to your preference.
Cayenne Pepper: This could be substituted with organic red pepper flakes - just adjust the amount to your preference. If you don't like spicy foods or will be serving this to children, it can be omitted.
Himalayan Pink Salt: This is my salt of preference, however, it can always be substituted with sea salt.
Fresh Basil: This is used as a garnish on top and for extra flavor, but if you don't have any, it can be omitted.
Serving Size: This recipe will make approximately (6) cups. Nutritional information is for 1 1/2 cups which is (1) serving.
