Add the cashews, grapeseed oil, lemon juice, apple cider vinegar, rosemary, and sea salt to a high-powdered blender. Blend for about 1 minute on medium-high speed, until smooth, and it looks like a thick paste that resembles cream cheese. **NOTE: If too thick, add a little warm water (1 Tbsp at a time), until desired consistency is formed.
In a medium saucepan, heat butter on medium-high heat and add garlic and sauté for a minute or so. Next, add flour and whisk until well incorporated and bubbly.
Slowly add Almond milk and pumpkin puree, whisking frequently. Once mixture becomes thick, add 1 1/2 cups vegan cream cheese, whisking frequently again. Add nutritional yeast, ground mustard, cajun seasonings, lemon juice, and red pepper flakes. Continue to whisk sauce until well combined.
Once fully combined, add drained pasta and toss in sauce carefully.
Garnish with red pepper flakes (optional) and enjoy!
Bon Appetite!
