Ingredients For Spaghetti With Broccoli

Spaghetti: This is the base of your dish, providing a hearty texture. I opted for gluten free spaghetti making this dish suitable for those who have gluten sensitivities. 

Broccoli Florets : a healthy and flavorful addition to any dish. They have a vibrant green color, crunchy texture, and they are packed with nutrients, including vitamins C and K.

Cashews: these nuts give the sauce a creamy and buttery texture with a rich flavor when soaked and blended.

Sweet Potato: adds a subtle sweetness and creamy texture to the sauce. It also boosts the nutritional value with its high vitamin A content.

Nutritional Yeast Flakes: These flakes impart a cheesy, umami flavor to the sauce, enhancing its richness while offering extra protein and vitamins, particularly vitamin B12.

Onion, garlic: onion adds flavor to the sauce, adding sweetness and depth.

How To Make Spaghetti With Broccoli

For this pasta and broccoli recipe, I cooked gluten-free spaghetti, then made a creamy cashew sauce with white sweet potato, then added broccoli for added nutrients. Broccoli is good for health, especially for our little ones. It is a powerful anti-oxidant and a great source of Vitamin C, beta-carotene, lutein and zeaxanthin. Antioxidants prevent damage to our cells.

Broccoli contains calcium and Vitamin K, which are both beneficial for bone health and prevention of osteoporosis. For more benefits of broccoli, check here.

  1. Michelle, I love your recipes and this one was wonderful, esp the sauce. Thank God cashews are not one of my allergies.

    1. Catherine, thank you very much. I’m so happy you enjoyed it. Cashew produces one of the creamiest sauces so I love it but soaked sunflower seeds are great as a substitute.

    1. Charlene, I believe it will be very gritty. If you have a regular blender, better to use it and blend 2-3 times taking breaks in between each blend to allow the motor to cool.

  2. I have issues with using raw cashews. I’ve been substituting silken tofu for the cashews in other recipes. Would that work here?
